In 1979, the price of electricity was $0.05 per kilowatt-hour. The price of electricity has increased at a rate of approximately 2.05% annually. If t is the number of years after 1979, create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10. Fill in the values of A, b, and c for this situation. Do not include dollar signs in the response.
c=A(b)^x
The equation that can be used to determine the number of years it would take for the price to be $0.10 is 0.10 = 0.05(1.0205)^t.
What is the equation that models the increase?
The equation that would be used is an exponential equation. An exponential equation is used because the rate of increase is a compound growth.
Exponential equations usually have this form: FV = PV( 1 + r)^t
Where:
FV = future value PV = present value r = rate of growth t = time0.10 = 0.05(1.0205)^t.

Daniela fue a la florería a comprar rosas rojas para regalar a su madre el día de su cumpleaños. Si una rosa cuesta $2.550 ¿Cuánto cuesta 2 docenas?
Answer:
2 docenas cuestan $61.200.
Step-by-step explanation:
Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:
12*2=24
Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:
$2.550*24=$61.200
De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.

G (x ), represents transformations on the parent function of y = (½) x Write the equation for g (x ).
Complete Question:
g(x), represents transformations on the parent function of [tex]y = (\frac{1}{2})^x[/tex].
Write the equation for g (x ) with the following transformations:
Reflect over y-axis, and shift right 7
Answer:
[tex]g(x) = (\frac{1}{2})^{-x-7}[/tex]
Step-by-step explanation:
Given
[tex]y = (\frac{1}{2})^x[/tex]
Represent the function as:
[tex]f(x) = (\frac{1}{2})^x[/tex]
Taking the transformations, one after the other:
Reflect over the y-axis.
This is represented by the rule: (x,y) ==> (-x,y)
So, we have:
[tex]f'(x) = (\frac{1}{2})^{-x}[/tex]
Shift right 7 units
This is represented by (x,y) = (x - b, y)
Where b represents the number of units
So, we have:
[tex]f'(x-7) = (\frac{1}{2})^{-x-7}[/tex]
Hence:
[tex]g(x) = (\frac{1}{2})^{-x-7}[/tex]

Y= -6/5x-7 and y=2/5x+1
Answer:
x = -5
y = -1
Step-by-step explanation:
Y= -6/5x-7 and y=2/5x+1
then:
-6/5x - 7 = 2/5x + 1
simplify:
-8/5x = 8
divide both sides by 8:
-1/5x = 1
multiply both sides by 5:
-x = 5
x = -5
y = 2/5(-5) + 1 = -2 + 1 = -1

A university will add fruit juice vending machines to its classroom buildings if the student body president is convinced that more than 20 percent of the students will use them. A random sample of n students will be selected and asked whether or not they would use the vending machines. A large-sample test for proportions at the significance level of a = 0.05 will be performed. The null hypothesis that the proportion of all students who would use the vending machines is 20 percent will be tested against the alternative that more than 20 percent of all students would use them. For which of the following situations would the power of the test be highest?
A .The sample size is n = 750, and 20 percent of all students actually use the vending machines.
B. The sample size is n = 750, and 50 percent of all students actually use the vending machines.
C. The sample size is n = 1,000, and 55 percent of all students actually use the vending machines.
D. The sample size is n = 1,000, and 25 percent of all students actually use the vending machines.
E. The sample size is n = 500, and 50 percent of all students actually use the vending machines.
Answer:
The power of the test will be highest for;
C. The sample size is n = 1,000, and 55 percent of all students actually use vending machines
Step-by-step explanation:
For a large sample test for proportions, we have;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]
Where;
[tex]\hat p[/tex] = The percentage of the hypothesized proportion = 20% = 0.20
p = The actual proportion
n = The size of the sample
The power of the test increases when;
The sample size 'n' is large
When the true vale of the measured items in the test is much larger than the value set as the null hypothesis
When the significant level is high
Therefore, we have;
The power of the test will be highest when the sample size is n = 1,000, and 55 percent of all students actually use vending machines

Solve for x in the diagram below.
Answer:
x = 20°
Step-by-step explanation:
here's your solution
=> it is given that whole angle is 90°
=> so, x + (3x + 10) = 90°
=> x + 3x + 10 = 90°
=> 4x + 10 = 90°
=>4x = 90 - 10
=> 4x = 80°
=.
=> x = 80/4
=> x = 20°
one angle is 20° and other 70°
hope it helps
Answer:
20 is your answer
x+3x+10=90 being right angle
4x=90-10
x=80/4=20
