hey please help. this has to do with exponential functions. i have to do 225 problems before midnight. it’ll mean a lot!!!
Answers
Answer:
Explanation:
To complete the missing values, we have to evaluate the function at the x-values given.
For example, to find the number below x = -1, we will put in x = -1 into y = (1/6)^x.
Putting in x = - 1 in y = (1/6)^x gives
[tex]y=(\frac{1}{6})^{-1}[/tex]which simplifies to give
[tex]y=\frac{1}{1/6}[/tex][tex]\rightarrow y=6[/tex]Similarly, for the missing value below x = -2, we put in x = - 2 into y = (1/6)^x to get
[tex]y=(\frac{1}{6})^{-2}[/tex]which simplifies to give
[tex]y=\frac{1}{(1/6)^2}[/tex][tex]\begin{gathered} \rightarrow y=6^2 \\ \rightarrow y=36 \end{gathered}[/tex]Similarly, for the missing value below x = 2, we put in x = 2 in y = (1/6)^x to get
[tex]y=(\frac{1}{6})^2[/tex]which simplifies to give
[tex]y=\frac{1}{36}[/tex]Hence, the missing value to be put in is 36.
To summerise, the missing values are

A is the point (-6, 5) and B is the point (-2,-3). (a) Find the equation of the straight line, I, that passes through point A and point B. Give your answer in the form y=mx+c.
Answers
The linear equation that passes through the point (-6, 5) and B is the point (-2,-3) is:
y = -2x - 7
How to find the linear equation?
A general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:
s = (y₂ - y₁)/(x₂ - x₁)
In this case, we have the points (-6, 5) and (-2,-3), then the slope is:
s = (-3 - 5)/(-2 + 6) = -8/4 = -2
Then we have:
y = -2*x + c
To find the value of the constant we use one of the points, I will use (-2, -3) to get:
-3 = -2*(-2) + c
-3 = 4 + c
-3 - 4 =c
-7 = c

You are offered two different sales jobs. The first company offers a straight commission of 6% of the sales. The second company offers a salary of $ 270 per week plus 2% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good?
Answers
One needs to sell $6750 worth of goods to make the straight commission be at least good to the secondary offer
Straight offer = 6% commission on the sales
Second offer = $270 + 2% of the sales
For the straight offer to be competitive with the second offer it should be able to cover the fixed income of $270
Let x be the sales made in the week
Formulating the equation we get the following:
6% of x = 270 + 2% of x
6/100x = 270 + 2/100x
4/100x = 270
x = 6750
So, for sales up to $6750, the second job offer is good, while for sales more than $6750 the first job offer is good

a cylinder shaped popcorn
Answers
Answer
Option C is correct.
Volume = 1,413 in³
Explanation
The volume of a cylinder is given as
Volume = πr²h
where
π = pi = 3.14
r = radius of the cylinder = ½ (Diameter) = ½ (10) = 5 inches
h = height of the cylinder = 1.5 feet = 1.5 (12 inches) = 18 inches
The conversion from feet to inches was done using 1 feet = 12 inches
So, we can calculate the volume now
Volume = πr²h
Volume = (3.14) × (5²) × (18)
Volume = 1,413 in³

Rudy has $90,000 in a savings account that earns 10% interest per year. The interest is not compounded. How much interest will he earn in 1 year?
Answers
The total interest earned by Rudy on the principal is $9000
Amount in Rudy's saving account = $90,000
Interest rate per year = 10%
The formula for simple interest is given:
A loan or deposit's principal amount serves as the foundation for simple interest. Compound interest, on the other hand, is calculated based on both the initial principal and the interest that is added to it each period.
Simple interest = P*R*T/100
where P = principal amount invested
R = rate of interest
T = time in years
Substituting the values in the formula we get:
Simple interest = 90000*10*1/100
= 9000
So, the interest amount is $9000

What are trigonometric functions?The trigonometric functions are real functions that connect the angle of a right-angled triangle to the ratios of its two side lengths. They are also known as circular functions, angle functions, or goniometric functions[1][2]. They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.
Given; tan t = 1
And the given condition is π/2 < t < 3π/ 2
this mean t lies in the 2nd quadrant because the value of t lies between 90 and 270 degrees.
This means tan t = tan (90 + 45)= cot 45 = 1
thus t = 235 degree
And thus sin t = sin 135 ° = sin (90+ 45) = cos 45 ° = 1/ √2

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of 4.3% per hour. How many hours does it take for the size of the sample to double? Note this is a continuous exponential growth model. Do not round any intermediate computations, and round your answer to the nearest hundredth.
Answers
Answer:
16.12 hours
Explanation:
A continuous exponential growth model is given below:
[tex]P(t)=P_oe^{rt}[/tex]• The growth rate, r = 4.3% = 0.043
,• t = time in hours
,• Po = Initial population
,• P(t) = Present population
We want to find the number of hours it takes the population to double. That is if the initial population, Po = 1
• The present population, P(t) = 1 x 2 = 2.
Substitute these values into the model above to get:
[tex]2=1(e^{0.043t})[/tex]Since natural logarithm(ln) is the inverse of exponential, take the natural logarithm of both sides to remove the exponential operator.
[tex]\begin{gathered} \ln (2)=\ln (e^{0.043t}) \\ \ln (2)=0.043t \end{gathered}[/tex]Divide both sides by 0.043.
[tex]\begin{gathered} \frac{\ln (2)}{0.043}=\frac{0.043t}{0.043} \\ t=\frac{\ln(2)}{0.043} \\ t\approx16.12 \end{gathered}[/tex]It will take 16.12 hours for the size of the sample to double.

The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). The cost for using 17 HCF of water is $32.13 and the cost for using 35 HCF IS 61.83. . What is the cost for using 19 HCF of water?
Answers
If the cost for using 35 HCF IS 61.83. . the cost for using 19 HCF of water is :$68.31.
How to find the cost price?Straight line: y=mx+b, m=slope, b=y-intercept
Let y=cost of using 19 HCF water
Let x =amount of water used
m=∆y/∆x =(61.83 - 32.13) / (35-19)
m=∆y/∆x =29.7 /16
m=∆y/∆x = 1.85625
m=∆y/∆x = 1.86 ($/HCF) (approximately)
equation: y=1.86x+b
Solving for b using point (19, 32.13)
32.13 =1.86×19+b
32.13=35.34+b
b=35.34 -32.13
b=3.21
equation:
f(x)=1.86x+3.21
f(25)=1.86×35+ 3.21
= 68.31
Cost of using 35 HCF water= $68.31

Angle JKL is an equilateral triangle jk=13x+5 KL=17x-19 and JL=8x+35
Answers
The value of x is 6, then the value of JK is 83, KL is 83 and JL is 83.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
An equilateral triangle is a shape with three sides that have an equal measure of side length.
The 3 sides of triangle JKL are equal to each other, therefore we can equate any of the two sides together to find the unknown variable called x.
So, JK = KL
JK = 13x + 5
KL + 17x - 19
13x + 5 = 17x - 19
Collect like terms;
17x - 13x = 19 + 5
4x = 24
x = 24/4
x = 6
We can now proceed to find the sides;
JK = 13x + 5
13 x 6 + 5
= 78 + 5
= 83
JK = 83
KL = 17x - 19
= 17 x 6 - 19
= 102 - 19
= 83
KL = 83
JL= 8x + 35
= 8 x 6 + 35
= 48 + 35
= 83
JL = 83
Hence, The value of x is 6, then the value of JK is 83, KL is 83 and JL is 83.
