A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.

Answers

Answer:

519.8 feet

Step-by-step explanation:

A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.

We solve this question using the Trigonometric function of Sine

sin theta = Opposite/ Hypotenuse

Theta = 12°

Hypotenuse = 2500 feet

Opposite = Height of the hill = x

Hence,

sin 12 = x/ 2500 feet

Cross Multiply

x = sin 12 × 2500 feet

x = 519.77922704 feet

Approximately = 519.8 feet

The height of the hill is 519.8 feet

if -1 is a root of f(x), which of the following must be true
A. a factor of f(x) is (x-1)
B. a factor of f(x) is (x+1)
C. both (x-1) and (x+1) are factors of f(x)
D. neither (x-1) nor (x+1) is a factor of f(x)

Answers

Option (B) is correct, A factor of f(x) is x+1.

What is function?

A function is a combination of different types of variable and constants in which for the different values of x the value of function y is unique.

Given that,

Function f(x) has one root, which is -1.

Implies that,

for the function f(x),

x = -1,

or (x+1) = 0,

So, (x+1) is the factor of the function f(x).

d) The intersection is on the vertical axis.

Step-by-step explanation:

a) A(2,4)

B (2,2)

Vecto BA (4, 2)

Vecto n (-4,2)

We have:

(2 - 4) x (X - (-2)) + (2 - (-2)) x (Y - 2) = 0

=> -2X + 4Y - 12 = 0

=> Y = X/2 +3

Let's find the value of y if (6,y) lies on the  plane:

The graph of F(x), shown below, resembles the graph
of G(x) x2, but it has been changed somewhat. Which of the
following could be the equation of F(x)?

A. F(x) = 6x2 - 2
B. F(x) = – x2 - 2
C. F(x) = 0.6x2 - 2
D. F(x) = x2 - 2

Answers

A. [tex]f(x)=0.6x^{2} -2[/tex], is the correct answer.

[tex]g(x)=x^{2}[/tex] is shifted down [tex]2[/tex] units and is bigger by 0.6 units, which makes the new equation: [tex]f(x) =0.6x^{2} -2[/tex].

The equation of the transformed function is F ( x ) = 0.6x² - 2

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) = x²

And , the graph of the function is shifted 2 units down and stretched by a a scale factor of 0.6 units

So , the transformed function is

F ( x ) = 0.6x² - 2

Hence , the transformed function is F ( x ) = 0.6x² - 2 and the graph is plotted

Step-by-step explanation:

The experimental probability that a person selected at random is going to City B is 19/50.

What is the experimental probability?

Experimental probability is a probability that is determined on the basis of a series of experiments.

The table shows the results of a survey of 100 people selected at random at an airport.

The total number of responses is;

The experimental probability that a person selected at random is going to City B is given by;

[tex]\rm Probability =\dfrac{Responses \ from \ city \ B}{Total \ responses}\\\\ Probability =\dfrac{38}{100}\\\\ Probability =\dfrac{19}{50}[/tex]

Step-by-step explanation:

The increase is (62 - 37), or 25, ounces.  Comparing this to the original quantity (37 oz), we divide 25 oz. by 37 oz., obtaining 0.676 (a ratio).  Multiplying this ratio by 100%, we get 68% (to the nearest percent).

Donovan spent $5.75 at the fruit stand. He bought 3 apples and 2 oranges. He spent the rest of the money on bananas.

Answers

The question is incomplete:

Donovan spent $5.75 at the fruit stand. He bought 3 apples and 2 oranges. He spent the rest of the money on bananas. The image with the price per fruit is attached. How many bananas did Donovan buy?

A. 1 banana

B. 2 bananas

C. 3 bananas

D. 4 bananas

Answer:

D. 4 bananas

Step-by-step explanation:

First, you have to consider that the total amount paid is equal to adding up the results of multiplying the price for each fruit for the number of fruits purchased which would be:

Total cost=(3*0.75)+(2*1.25)+0.25x, x is the number of bananas

Total cost=2.25+2.5+0.25x

Now, you can replace the total cost with 5.75 that is the amount Donovan spent and solve for x:

5.75=2.25+2.5+0.25x

5.75-2.25-2.5=0.25x

1=0.25x

x=1/0.25

According to this, the answer is that Donovan bought 4 bananas.

Step-by-step explanation:

From the question, we have;

∠1 and the 90° are supplementary angles

∴ ∠1 = 180° - 90° =  90°

2) ∠2 is vertically opposite to the 90° angle, therefore;

∠2 = 90°

3) ∠3 is vertically opposite to ∠1 , therefore;

∠3 = 90°

4) ∠4 is the corresponding angle to the given 90° angle, therefore;

∠4 = 90°

5) ∠5 is the corresponding angle to ∠1, therefore;

∠5 = ∠1 = 90°

6) ∠6 and ∠2 are corresponding angles;

∴ ∠6 = ∠2 = 90°

2. The volume of a cylinder varies jointly with its height and the square of the radius. A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. Another spice container is 3 inches tall with a radius of 1.5 inches, what would be the volume?

Answers

Answer:

Volume=21.195 cubic inch

Step-by-step explanation:

The volume of a cylinder varies jointly with its height and the square of the radius is expressed as

V∝hr^2

Introducing our constant of proportionality,K we have that

V =Khr^2

Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that

V =Khr^2

7.85=K 2.5 X 1^2

K=7.85/2.5 x1

K=3.14

Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?

V =Khr^2

V=3.14 X 3 X 1.5^2

Area = L × W squared units.

Given;

Width of painting= 25m

Length of painting= 34m

Area of rectangle = L x W

= 25 x 34
