Help me out please!!!! (Operations of Functions) Giving alot of points for this if you answer these both two correctly.
Answers
Answer:
1) 20
2) 4
Step-by-step explanation:
1)
I) Substitute t with 2:
2² + 5(2) + 6
II) Simplify/Evaluate:
2² + 5(2) + 6
4 + 10 + 6
14 + 6
20
2)
I) Setup the equation:
g(t) = 5t - 2 = 18
5t - 2 = 18
II) Solve it:
Reorder the terms:
-2 + 5t = 18
Add 2 to each side of the equation:
-2 + 2 + 5t = 18 + 2
Simplify:
0 + 5t = 18 + 2
5t = 18 + 2
5t = 20
Divide each side by 5:
t = 4

PLEASE HELP WILL MARK BRAINLIEST!!! A movie theater is offering a special summer pass. Passholders pay $8 per movie for the first 5 movies and watch additional movies for free, up to a maximum of 15 movies. The function C gives the total cost, in dollars, for a passholder to watch n movies.
1. Is function C a piecewise function? Explain your reasoning.
2. Draw a graph to represent C.
3. Describe, as completely as possible, the domain of C.
4. Describe, as completely as possible, the range of C.
Answers
The equation to describe this will be y = 8x. It is assumed that Pass holders pay $8 each movie for the first five films. After five films, up to fifteen films, additional films are free. This will be represented by the function y = 40.
What is meant by equation?When two expressions are joined by an equal sign, a mathematical statement is called an equation. An equation is something like 3x - 5 = 16. By solving for x, we discover that x equals 7, which is the value for the variable. An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."Equations can be classified as either conditional equations or identities. Any value of the variables results in an identity being true. Only certain values of the variables in a conditional equation result in truth.To learn more about equation, refer to:

* HELP* A book sold 39,900 copies in its first month of release. Suppose this represents 8.2% of the number of copies sold to date. How many copies have been sold to date? Round your answer to the nearest whole number
Answers
Answer:
Total copies sold= 486,585
Step-by-step explanation:
Giving the following information:
Number of copies sold in the first month= 39,900
% of copies sold in the first month= 8.2%
To calculate the total number of copies sold, we need to use the following formula:
Total copies sold= Number of copies sold in the first month/% of copies sold in the first month
Total copies sold= 39,900 / 0.082
Total copies sold= 486,585

Answer:
Remember that the roots are the values of the variable when the expression equals 0.
a: 4 + 3 = 7 and 4*3 = 12 so we have (x + 3)(x + 4) with roots -3, -4
b: -4 + -2 = -6 and -4*-2=8 so we have (t-2)(t-4) with roots 2, 4
c: 2*-4 + 6 = -2 and -4*6=24 so we have (2n+6)(n-4) with roots -3, 4
d: -7+-4 = -11 and -7*-4=28 so we have (y-4)(y-7) with roots 4, 7
Sara hina and arsalan has rupees 930 if Sara has 7 more than Hina and arsalan has 3 times what sara has how much do they have
Answers
Answer:
Step-by-step explanation:
Let us represent:
Number of rupees that:
Sara has = x
Hina = y
Arsalan = z
Sara,Hina and arsalan has rupees 930
x + y + z = 930..... Equation 1
if Sara has 7 more than Hina
x = y + 7
y = x - 7
Arsalan has 3 times what sara has
z = 3x
We substitute x - 7 for y and 3x for z in Equation 1
x + y + z = 930..... Equation 1
x + x - 7 + 3x = 930
5x - 7 = 930
5x = 930 + 7
5x = 937

A polling firm wants to use a one-sample z interval to estimate what proportion of voters in a country plan on
voting for a certain candidate. They want the margin of error to be no more than £3% at 99% confidence.
What is the smallest sample size required to obtain the desired margin of error?
Answers
Answer:
1844
Step-by-step explanation:
For polling firm survey on voters, the smallest sample size which is required to obtain the desired margin of error, is 1850.
What is margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
[tex]MOE=z\times\dfrac{\sigma}{\sqrt{n}}[/tex]
Here, z is the critical value and n is the sample size.
Here, a polling firm wants to use a one-sample z interval to estimate, the number of proportion of voters in a country plan on voting for a certain candidate.
The margin of error for this test is 3% or 0.03 and the confidence interval is 99 percent.
The z value on the confidence interval of 99 percent is 2.576. Here, the standard deviation for this survey is 50 percent, or 0.50.
Put the value in the above formula as,
[tex]0.03=(2.576)\times\dfrac{0.5}{\sqrt{n}}\\n\approx1850[/tex]
Hence, for polling firm survey on voters, the smallest sample size which is required to obtain the desired margin of error, is 1850.

A rectangle has sides of length 8cm and 3.2cm. Calculate the angle between the diagonal and a shorter side.
Answers
Answer:
The angle is 68.2 degrees
Step-by-step explanation:
Let us have the shorter side as the width
In that case, the opposite will be the length which is 8 cm
The diagonal is the hypotenuse
The short side is the adjacent
The trigonometric ratio that links the opposite and the adjacent is the tan
tan of an angle is the ratio of its opposite to the adjacent
In this case,
tan theta = 8/3.2
theta = arc tan (8/3.2)
theta = 68.2 degrees

Answer:
The scale Myra should use is one graph unit = 400 km or;
←--→ = 400 km
Step-by-step explanation:
The question relates to the representation of scale drawing
The actual distance between Perth and Sydney = 3294 kilometers
The given coordinates of Perth on the grid = (1.3, 3.4)
The given coordinates of Sydney on the grid = (9.2, 3.3)
The measure of the distance between Perth and Sydney, 'd', is given by using the following formula for finding the distance between two points given their 'x', and 'y' coordinates;
[tex]d = \sqrt{\left (x_{2}-x_{1} \right )^{2}+\left (y_{2}-y_{1} \right )^{2}}[/tex]
Therefore, by substitution, we have;
[tex]d = \sqrt{\left (9.2-1.3 \right )^{2}+\left (3.3-3.4 \right )^{2}} = \sqrt{\left (7.9 \right )^{2}+\left (-0.1 \right )^{2}} = \dfrac{\sqrt{6242} }{10} \approx 7.9[/tex]
d ≈ 7.9 units
Therefore, we have;
7.9 units of the graph = 3294 kilometers
1 unit of the graph ≈ 3294/7.9 km = 416.962025316 km ≈ 416.96 km
Therefore, the scale Myra should use for her map is 1 unit = 400 km.
Determine the number of solutions given the graph.
