f(x)=x^2. What is g(x)
Answer:
D
Step-by-step explanation:
The standard form for a parabola is ax^2+bx+c. In this equation, b=0 and c=0. For g(x), you would plug in your y-value that was given (which is 4) and you would plug in your x-value that that given (which is 1). Use PEMDAS. The correct answer is the one that is true.
A. g(x) = (4x)^2
4 = (4(1))^2
4 = 16. (not true)
B. g(x) = 1/4 x^2
4 = 1/4 (1)^2
4 = 1/4 (not true)
C. g(x) = 16x^2
4 = 16(1)^2
4 = 16 (not true)
D. g(x) = 4x^2
4 = 4(1)^2
4 = 4. (true --> correct answer)

At what rate is the tip of the shadow moving away from the pole when the person is 25 ft from the pole?
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question and the graph in the attached file.
[tex]\to \frac{12}{l}= \frac{5.5}{l-x}\\\\\to 12(l - x) = 5.5l\\\\\to 12l - 12x = 5.5l\\\\\to 12l -5.5l = 12x\\\\\to 6.5l =12x\\\\\to 12x = 6.5l \\\\\to x = ( \frac{6.5}{12})l \\\\[/tex]
Calculating the Derivative of the above value:
[tex]\to \frac{dx}{dt} = (\frac{6.5}{12}) \frac{dl}{dt}\\\\\to \frac{dl}{dt} = (\frac{12}{6.5}) \frac{dx}{dt}\\\\\to \frac{dx}{dt} = 2 \\\\ \to \frac{dl}{dt} = ( \frac{12}{6.5} \times 2)[/tex]
[tex]=\frac{24}{6.5} \\\\= \frac{48}{13} \ \frac{ft}{sec}[/tex]
by subtracting the rate of the shade from that of the man:
[tex]\to \frac{48}{13} - 2 \\\\ \to \frac{48-26}{13} \\\\ \to \frac{22}{13} \ \frac{ft}{sec}[/tex]

Answer:
C.-85
Step-by-step explanation:
An arithmetic sequence is a sequence where the difference between each consecutive term is the same.
The nth term of an arithmetic sequence.
= a + (n - 1)d
The 61st term of the sequence is 85.
What is an arithmetic sequence?
It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8 is an arithmetic sequence.
We have,
-5, -7/2, -2, -1/2, 1
a = -5
d = -7/2 + 5
d = 3/2
Now,
The nth term of an arithmetic sequence.
= a + (n - 1)d
Now,
n = 61
61st term:
= -5 + (61 - 1)(3/2)
= -5 + 60 x 3/2
= -5 + 30 x 3
= -5 + 90
= 85
Thus,
The 61st term of the sequence is 85.

A study conducted on American families shows that 18% of these families have medical bills of more than $10,000. Find the probability that among 5 randomly selected American families, at least one has medical bills of more than $10,000.
Answer:
the probability is 0.6293
Step-by-step explanation:
The computation of the probability is shown below:
Given that
n = 5
P = 0.18
As it represents the binomial distribution
P(X = x) = [tex]^NC_x[/tex]× p^x × (1 - p) ^(n - x)
P(X > 1) = 1 - P(X < 1)
= 1 - P(X = 0)
= 1 - ( [tex]^5C_0[/tex]× (0.18) ^0 × (0.82) ^5)
= 1 - 0.3707
= 0.6293
hence, the probability is 0.6293
A company has actual unit demand for three consecutive years of 124, 126, and 135. The respective forecasts for the same three years are 120, 120, and 130. Which of the following is the resulting MAD value that can be computed from this data? A. 3 B. 5 C. 15 D. 123
Answer:
B. 5
Step-by-step explanation:
Computation for Which of the following is the resulting MAD value that can be computed from this data
Using this formula
MAD Value=[(Actual unit demand-Respective forecasts)/Number of years]
Let plug in the formula
MAD Value = [(124 - 120) + (126 - 120) + (135 - 130)]/3 years
MAD Value =(4+6+5)/3 years
MAD Value = 15/3 years
MAD Value = 5
Therefore the MAD value that can be computed from this data is 5

Which expression gives the measure of angle
XYZ in the diagram below?
A. (154° + 46°)
B. 154° + 46°
c. 1/2 (154° -46° )
D. 154° - 46°
Answer:
C. 1/2(154-46) hope this helps :)
Step-by-step explanation:
The measure of the angle XYZ will be [tex]\frac{1}{2} (154^0 -46^0 )[/tex] i.e. option C.
What is angle ?Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
We have,
Arc ST = 46°, and
Arc XZ = 154°
Now,
We know that the measure of the arc is same as that of central angle.
Now,
Join X and T,
Now,
We know that, the angle subtended at the center is the average of the measure of arc intercepted by its angle and its vertical angles.
So,
Angle XTZ [tex]=\frac{154}{2}[/tex]
And,
Angle SXT [tex]=\frac{46}{2}[/tex],
Now,
∠XTZ = ∠XYZ + ∠SXT [Exterior angle is equal to the sum of interior opposite angles]
So,
∠XYZ = ∠XTZ - ∠SXT
Now,
Substituting the values,
We get,
∠XYZ [tex]=\frac{154}{2}-\frac{46}{2}[/tex]
i.e.
∠XYZ [tex]=\frac{1}{2} (154-46)[/tex]
So, measure of angle XYZ is [tex]\frac{1}{2} (154-46)[/tex] .
Hence, we can say that the measure of the angle XYZ will be [tex]\frac{1}{2} (154^0 -46^0 )[/tex] i.e. option C.

natalie went skydiving, she jumped out of the plane at 3,080 feet above the ground. at 1,710 feet above the ground her parachute deployed, and instead of continuing to fall, she rose 35 feet. at this point, how far is she from the plane?
Answer: 1675 feet
Step-by-step explanation: Starting at 3080 feet she falls 1710. We subtract 1710 from 3080 and get her position at 1370 feet above the ground. She then rises 35 feet. 1370+35 = 1405 feet above the ground.
We know that the plane is 3080 feet above the ground, and that Natalie is only 1405 feet above the ground. We just have to find the difference in their positions in order to find out how far she actually is from the plane. 3080-1405 = 1675 feet

Consider the systems of equations below.
System A)
X^2 + y = 17
Y = -1/2x
System B)
Y = x^2 - 7x + 10
Y = -6x + 5
System C)
Y = -2x^2 + 9
8x - y = -17
Determine the number of real solutions for each system of equations.
System A) ____
SystemB) ____
System C) ____
Based on the systems of equations given, the number of real solutions for each system is:
System A - 2 solutions. System B - 0 solutions. System C - 1 solution. How many solutions will the systems of equations give?To find out the number of solutions, you should plot the equations on a graph.
When system A is plotted as shown attached, you notice that line y = 1/2x intersects x² + y² = 17 twice. It therefore has two solutions.
When system B is plotted, y = -6x + 5 does not intercept y = x² + 7x + 10 which means that there are no real solutions.
System C shows only one real solution because 8x - y = -17 intercepts y = -2x² + 9 once.

Write an equation for the line that passes through (-2,4) and (0,7)
Answer:
y = 3/2x + 7
Step-by-step explanation:
The slops is rise over run, so in this case the slope is 3/2 because it goes up 3 units while going 2 units to the right.
The points (0,7) is on the y axis. This means that 7 is the y intercept
With this information, we can follow the format of the slope intercept equation: y = mx + b
m stands for the slope and b stands for the y intercept. Plugging the information in, our equation is:
y = 3/2x + 7

Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
