Answers

Answer 1

Answer:

[tex]\begin{gathered} f(-4)=-\frac{4}{3} \\ f(1)=4 \\ f(3)=1 \end{gathered}[/tex]

Step-by-step explanation:

These types of functions are called Piecewise-defined functions since it use a different formula for different parts of its domain because it has a point of discontinuity.

We have the following function:

[tex]f(x)=\begin{cases}-\frac{1}{3}x^2+4\rightarrow ifx\ne1^{} \\ \text{ 4 if x=1}\end{cases}[/tex]

So, to find f(-4), we need to substitute x=-4 into the function for x≠1.

[tex]\begin{gathered} f(-4)=\frac{-1}{3}(-4)^2+4 \\ f(-4)=-\frac{1}{3}(16)+4 \\ f(-4)=-\frac{16}{3}+4 \\ f(-4)=-\frac{4}{3} \end{gathered}[/tex]

Now, for f(1) we know that the outcome is 4.

[tex]f(1)=4[/tex]

Then, for f(3), substitute x=3 into the function for x≠1.

[tex]\begin{gathered} f(3)=-\frac{1}{3}(3)^2+4 \\ f(3)=-\frac{1}{3}(9)+4 \\ f(3)=1 \end{gathered}[/tex]

Omar and Zina Aboud found that the dealers cost of the base price was $16.558.16 and the dealer's options cost was $611.60. The consumer paid the $476.00 destination charge. If the percent of the dealer's cost is 92% and the percent of dealer's options cost is 88%, find the car's sticker price.

Answers

We want to calculate the sticker price. The sticker price is given by the formula

[tex]\text{sticker price = base }price+\text{ options + destination charge}[/tex]

We are told that the destination charge is 476. We should determine the base price and the options to find the price sticker.

We are told that the dealer's cost of the base price is 92% of the pase price. So we have the equation

[tex]16558.16=\frac{92}{100}\cdot\text{base price}[/tex]

so if we divide both sides by 92 and multiply by 100 we get

[tex]\text{base price = }16558.16\cdot\frac{100}{92}=17998[/tex]

Now, applying the same principal for the options, we have

[tex]611.60=\frac{88}{100}\text{options}[/tex]

which means that

[tex]\text{options}=611.6\cdot\frac{100}{88}=695[/tex]

Replacing these values in the original equation we have that

[tex]\text{sticker price = }17998+695+476=19169[/tex]

so the sticker price would be 19169

Answers

John recieved the greater discount and the original price of the bike is $120

John purchased the bike at a 20% discount off the original

price.

Let the price of the bike be x

The price at which John purchased the bike is x - 20% of x

= x - (20/100)x

=(80/100)x

Raul brought the bike at original price.

Raul's cost price is x

x is greater than (80/100)x

Raul purchased at a greater price than John, so the greater discount is recieved by John.

John got discount = (20/100) x

He saved = $24

(20/100)x = 24

2. The design of the Trieste was based on the design of a hot air balloon built by Auguste Piccard, Jacques's father. In 1932, Auguste rode in his hot-air balloon up to a record-breaking height.A. Auguste's ascent took 7 hours and went up 51,683 feet. Write a relationship y = kx to represent his ascent from his starting location.B. Auguste's descent took 3 hours and went down 52,940 feet. Write another relationship to represent his descent. C. Did Auguste Piccard end up at a greater or lesser altitude than his starting point? How much higher or lower?

Answers

ANSWER

A. y = 7383.3x

B. y = 17646.7x

C. Lesser altitude; 1257 feet

EXPLANATION

A. We want to write a proportional relationship between the time it took him to ascend and the total height he reached:

y = kx

where x = time taken

y = distance (height reached)

k = constant of proportionality

We have to find k for the relationship.

So, we have that:

[tex]\begin{gathered} 51683\text{ = k }\cdot\text{ }7 \\ \Rightarrow\text{ k = }\frac{51683}{7} \\ k\text{ = }7383.3\text{ ft/hr} \end{gathered}[/tex]

This constant of proportionality (between distance and time) is called speed.

Therefore, the relationship for his ascent is:

y = 7383.3x

B. For his descent, we also have to find k in:

y = kx

We have that:

[tex]\begin{gathered} 52940\text{ = k }\cdot\text{ 3} \\ k\text{ = }\frac{52940}{3} \\ k=\text{ }17646.7\text{ ft/hr} \end{gathered}[/tex]

Therefore, the relationship for his descent is:

y = 17646.7x

C. To find out if he reached a greater or lesser altitude than his starting point, we have to subtract his altitude during ascent from his altitude during descent.

If the value is positive then he ended up at a lesser altitude but if it is negative, he ended up on a greater altitude.

That is:

52940 - 51683

= 1257 feet

Since it is positive, that means that he descended more feet than he ascended and so, he ended up at a lesser altitude than his starting point, 1257 higher.

A sequence of positive integers with 2020 terms is called an FT sequence if each
term after the second is the sum of the previous two terms. For example, if the
first two terms of an FT sequence are 8 and 7, the sequence would begin
8,7,15, 22, 37,.... For some positive integer m, there are exactly 2415 FT sequences
where the first two terms are each less than 2m and the number of odd-valued
terms is more than twice the number of even-valued terms. What is the value of m?

(A) 21
(B) 69
(C) 115
(D) 35
(E) 105

Answers

The value of m will be 35.

Consider the FT 0, 1, 1, 2, 3, 5, 8, 13, 21, 24,45,.......

The numbers are arranged in order of even, odd, odd, even, odd, odd, even, odd, odd, even,.......

Hence, the loop contains 3 elements. If the number of terms is 2020 terms, then we have 673 loops + 1 element. (That is 3* 673 +1 = 2020) The last element will start the new loop and it is an even number.

In the other hand with 2019 terms, we have number of odd = 2* number of even. But the last term is even. That makes number of odd < twice number of even and it contradicts with the condition.

However in this case, the 2020th term is even and so there are fewer than twice as many odd valued terms as there are even-valued terms.

Thus, there are m2 + m × (m − 1) FT sequences that satisfy the required conditions.

Since there are 2415 such FT sequences, we may solve m2 + m × (m − 1) = 2415 by trial and error.

Evaluating m2 + m × (m − 1) when m = 30, we get 302 + 30 × 29 = 1770, and so m is greater

than 30.

When m = 33, we get 332 + 33 × 32 = 2145.

When m = 34, we get 342 + 34 × 33 = 2278.

When m = 35, we get 352 + 35 × 34 = 2415, as required.

Leonard is 68 years less than quadruple Sheldon's age. In 12 years, Leonard's age will be 24 years less than two times Sheldon's age. What are their 2 ages?

Answers

Sheldon is 16 4/7 years old, while Leonard is 21 1/7.

We are given the correlations between two numbers in this sort of query, specifically the data when their ages are contrasted now and in the future.

Let x represent Leonard's age.

We can infer Sheldon's age from the question as being 4x - 68.

The following equation results from the question:

x + 12 = 2((4x - 68) + 12) - 24

Fix x,

=> x + 12 = 2(4x - 68 + 12) - 24

x + 12 = 2(4x - 56) - 24

x + 12 = 8x - 112 - 24

x - 8x = -136 - 12

-7x = - 148

x = 148 / 7 or 21 1/7

Now, simply multiply 4x by 68 to get Sheldon's age.

=> 4x - 68

=> 4 * 148/7 - 68

=> 592/7 - 68

=> 116/7 or 16 4/7

Leonard is therefore 21 1/7 years old, while Sheldon is 16 4/7.

What is the slope of the line that passes through the points (4, -2) and (4, 10)?
Write your answer in simplest form.

Answers

The slope of the line that passes through the points (4, -2) and (4, 10) is 0. The slope of a line is 0 if it is horizontal. This function is constant.

What is slope?

The ratio of the "vertical change" to the "horizontal change" between (any) two unique points on a line is used to compute slope. The ratio can also be written as a quotient ("rise over run"), which produces the same number for every two distinct points on the same line. A declining line has a negative "rise." The line might be useful, as determined by a road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.

The slope's absolute value serves as a gauge for a line's steepness, incline, or grade. A steeper line is indicated by a slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical.

If a line rises from left to right, it is said to be growing. The slope is upward, or m>0.

If a line slopes downward from left to right, it is diminishing. The slope, m0, is negative.

The slope of a line is 0 if it is horizontal. This function is constant.

A line's slope is ambiguous if it is vertical.

In other terms, the rise is (y2 y1) = y. The rise of a road between two points is the difference in the altitude of the road at those two sites, say y1 and y2. The run, or (x2 x1) = x, is the difference in distance from a given point measured along a level, horizontal line for relatively small distances where the Earth's curvature may be disregarded. Here, the ratio of the altitude change to the horizontal distance between any two places on the line is used to define the slope of the road between the two points.

In mathematical language, slope m of the line is

Answers

Answer:

C A submarine goes 3.8 feet below the surface of the ocean and then goes 2.5 feet farther down

Explanation:

Option A

[tex]\begin{gathered} 4.3^0F\approx4^0F \\ 1.9^0F\approx2^0F \\ \text{Estimated change in temperature=}4^0F-2^0F=2^0F \end{gathered}[/tex]

Option B

[tex]\begin{gathered} 4.1\text{ meters}\approx4\text{ meters} \\ 2.3\text{ meters}\approx2\text{ meters} \\ \text{Estimated change in the balloons's height}=4-2=2\text{ meters} \end{gathered}[/tex]

Option C

A sample of 342 students at a university is surveyed. The students are classified according to gender ("female" or "male"). They are also classified according tomajor ("blology", "business", "engineering", "mathematics", or "computer science"). The results are given in the contingency table below.Biology Business Engineering Mathematics Computer scienceFemale4623501837Male4815461544What is the relative frequency of male students in the sample?Round your answer to two decimal places.0Х5.?

Answers

The relative frequency of an event is the quotient of the division between the event and the total number of the sample

From the given table

Add the numbers of males to find their total

[tex]48+15+46+15+44=168[/tex]

Then add the numbers of females and males to find the total of the sample

[tex]168+46+23+50+18+37=342[/tex]

Now, divide the number of males by the total to find the relative frequency

[tex]\begin{gathered} R\mathrm{}F=\frac{168}{342} \\ R\mathrm{}F=0.4912280702 \end{gathered}[/tex]

Round it to 2 decimal places, then

The relative frequency of the male students = 0.49

Read the excerpt from "An Image of Africa: Racism in Conrads Heart of Darkness.But more important by far is the abundant testimony about Conrad's savages which we could gather if we were so inclined from other sources and which might lead us to think that these people must have had other occupations besides merging into the evil forest or materializing out of it simply to plague Marlow and his dispirited band. For as it happened, soon after Conrad had written his book an event of far greater consequence was taking place in the art world of Europe. This is how Frank Willett, a British art historian, describes it:Gauguin had gone to Tahiti, the most extravagant individual act of turning to a non-European culture in the decades immediately before and after 1900, when European artists were avid for new artistic experiences, but it was only about 19045 that African art began to make its distinctive impact. One piece is still identifiable; it is a mask that had been given to Maurice Vlaminck in 1905. He records that Derain was "speechless" and "stunned" when he saw it, bought it from Vlaminck and in turn showed it to Picasso and Matisse, who were also greatly affected by it. Ambroise Vollard then borrowed it and had it cast in bronze . . .
