The exponential function is given by f(x) = 7ˣ
Exponential Function
An exponential function is in the form:
y = abˣ
Where a is the initial value of y, b is the multiplier, y and x are variables.
Given the y-intercept is (0,1), hence:
1 = ab⁰
a = 1
Also f(2) = 49, hence:
49 = (1)(b)²
b = 7
The exponential function is given by f(x) = 7ˣ

Two lines, M and N, are represented by the following equations:
Line M: y = x + 3
Line N: y = −2x + 6
Which of the following options shows the solution to the system of equations and explains why? Please do it quickly
Group of answer choices
(1, 4), because the point does not lie on any axis
(1, 4), because one of the lines passes through this point
(1, 4), because both lines pass through this point
(1, 4), because the point lies between the two axes
Answer:
The answer is (1,4) because both lines pass through this point.
Step-by-step explanation:
To find a solution to a system of equations, both lines have to pass through the same point. If both lines intercept at the same point, that means that point is the solution to the system of equations.
One study, based on responses from 1,017 randomly selected teenagers, concluded that 39% of teenagers cite grades as their greatest source of pressure. use a 0.05 significance level to test the claim that fewer than half of all teenagers in the population feel grades are their greatest source of pressure
Answer:
The hypothesis formulae will be
H0 : p = 0.5
Ha : p < 0.5
we will reject H0.
Step-by-step explanation:
Number of responses ( n ) = 1017
percentage( p ) = 39% = 0.39
significance level ( ∝ ) = 0.05
P0 = 50% = 0.5
Test the claim that fewer than half of all teenagers feel the pressure
The hypothesis formulae will be
H0 : p = 0.5
Ha : p < 0.5
Perform the test statistic
Test statistic ( Z ) = -6.957
P-value < 0.05 we will reject H0.

You love watching movies on your phone! Unfortunately each movie uses about
0.75GB. For this billing cycle, you’ve already used up 3 GB and your cellular plan
has a 15 GB data limit. How many movies can you watch without going over your
data limit?
1) Let M represent the number of movies you watch. Write an INEQUALITY to
model the number of movies that can be watched without going over the
data limit. Solve the inequality and show all of your work.
Answer:
[tex].75M+3<15[/tex]
[tex]M<16[/tex]
Step-by-step explanation:
This is a linear inequality so you would solve it as any normal linear system:
Subtract 3 from both sides to isolate the M term :
[tex].75M<12\\[/tex]
Divide each side by .75 to isolate M:
[tex]M<16[/tex]
That means you can watch less than 16 movies and stay under your 15GB limit.

Answer:
H = .298
Step-by-step explanation:
First lets plug in 1.5 for R and 16 for Surface area to get the following
2*pi*1.5^2+2*pi*h = 16 We are solving for H or height
Lets simplify this out a bit to get
16 = 14.13+6.28h
Subtract 14.13 from both sides
1.87 = 6.28h
h= .298
To check our answer lets plug the height into the equation
2*pi*1.5^2+2*pi*.298 = 16
Yes the height or H is .298
To check your answer just plug back what you got before into the equation
The angle measurements in the diagram are represented by the following expressions.
Answer:
x = 20 , ∠ A = 125°
Step-by-step explanation:
∠ A and ∠ B are alternate angles and are congruent, then
6x + 5 = 4x + 45 ( subtract 4x from both sides )
2x + 5 = 45 ( subtract 5 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20
Then
∠ A = 6x + 5 = 6(20) + 5 = 120 + 5 = 125°

Answer:
y = 7
Step-by-step explanation:
The slope is ...
m = (7 -7)/(0 -4) = 0
The y-intercept is the point (0, 7), so the slope-intercept equation is ...
y = mx +b
y = 0·x +7
Simplifying this puts it in standard form:
y = 7

A toy rocket is launched from a platform that is 48 feet high. The rocket’s height above the ground is modeled by h = -16t 2+ 32t + 48. a. Find the maximum height of the rocket.
Answer:
The maximum height of the rocket is 64 ft.
Step-by-step explanation:
The -t^2 term tells us that the graph of this function is a parabola that opens down. The x-coordinate of the axis of symmetry is
-b
x = -----------
2a
which here is:
-32
x = ------------ = 1
2(-16)
The value of this function at t = 1 is
h(1) = -16(1)^2 + 32(1) + 48, or 64 ft
The maximum height of the rocket is 64 ft.
