Answer:
9.5 in
Step-by-step explanation:
The receiver is placed at the focus of the parabola at a distance of 1/4a from the vertex. Here that would be 1/(4*(1/38)) or 38/4 inches or 9.5 in
The receiver lies 9.5 inches far from the vertex of the cross-section.
Given that,
The cross-section (with units in inches) of a parabolic satellite dish can be modeled by the equation y=1/38 x².
To determine how far is the receiver from the vertex of the cross-section.
A parabola is a cross-section cut out of the cone and represented by an equation, y =4ax².
Here,
The receiver is located near the parabola's focus, 1/4a away from the vertex. That would be 1/(4×(1/38)) or 38/4 inches or 9.5 in. in this case.
Thus, the receiver lies 9.5 inches far from the vertex of the cross-section.

[tex]\boxed{\sf Slope=-\frac{1}{2}}[/tex]
Step-by-step explanation:
To find a slope, we use two points of a line, we can find slope of a line by finding the rise over run.

A certain book had an original rating of 27 out of 30 points on a survey chart. Each month, the rating fell by 3 points. Express the number of points as a function of m, the number of months since the release.
(A) f(m)=3m (B) f(m)=3m−27 (C) f(m)=30−3m (D) f(m)=27−3m (E) f(m)=3−27m
Answer:
D.) f(m)=27−3m
Step-by-step explanation:
Given that:
Original rating = 27
Total possible rating points = 30
Drop in rating point per month = 3
m = number of months since release :
Hence,
F(m) = original rating - drop in rating per month * number of months since release
F(m) = 27 - 3(m)
F(m) = 27 - 3m
One month the store sold 12 electric guitars.If that Was 60% of their sales for the month how many guitars did they sell that month
Answer:

1/2 + z/7 = 5/14
What is Z?
nvm thts confusing sorry
Answer:
z = -1
Step-by-step explanation:
1/2 + z/7 = 5/14
Multiply both sides of the equation by 14
7 + 2z = 5
Subtract 7
2z = -2
Divide both sides by 2
z = -1
Plug -1 in for z to check
1/2 + (-1/7) = 5/14
The slope is 9 (write it as a fraction ) ———and the y intercept is ———
Answer:
The slope is 9/1 (I don't know if you have to write x) and the y-intercept is 22.50
Step-by-step explanation:
if the slope is 2x the y intercept is 12. If the slope is 4x then the y-intercept is 15 . Every time your x increases by 2 your y-intercept goes up by three. In the question, it's asking you to find out the one for the number 9. 8+2 is 10 not nine so you divide 3 by 2 and get 1.5 so 21+1.5 is 22.50

5. Amy has 10 yd of fence to put around a tree. She uses all the fence to make six
sections that are the same length. Which expression does NOT equal the length of one
of these sections in yards?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
From the question, we are informed that Amy has 10 yd of fence to put around a tree and that she uses all the fence to make six sections that are the same length.
The expression that will be equal to the length of one of these sections in yards will be:
= 10 yards / 6
= 1.67 yards or 1 2/3 yards
This means that any option that you see that is different from the answer above will be the answer based on your question.
Find the equation of the line that has a slope of 1/2 and passes through the point (-4,6).
A. x - 2y = -16
B. x + y = -16
C. 2x - y = 8
D. x + 2y = -8

A baby was born with a weight of 7 pounds and then began to gain 1.25 pounds per month. Write an equation for W, in terms of t, representing weight, in pounds, of the newborn baby t months after birth.
Answer:
7+1.25m=t
Step-by-step explanation:
The equation that represents the weight of the baby will be W = 1.25 t + 7.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
A child was brought into the world with a load of 7 pounds and afterward started to acquire 1.25 pounds each month.
Let 'W' be the weight of the baby and 't' be the number of months. Then the equation is given as,
W = 1.25 t + 7
The equation that represents the weight of the baby will be W = 1.25 t + 7.

Step-by-step explanation:
2x2x2x5 equals 40
what's the midpoint of (-10,3) and (0,9)
Answer:
To find the midpoint we need to find the point which is the same distance between the x and y values in both points. For example the distance to a point that will be shared among the 2 x's is -5. -10 (x1) and 0 (second x value) are both 5 units away from -5. to -5 is the x of our new point: (-5, y)
Now do the same for the y value:
9-3=6
6 is the y value of our new point
(-5, 6) is your answer

a farmer harvests crops on 2/5 acre of land in 1/3 hour.
At what rate, in acres per hour, does the farmer harvest crops?
put your answer in the box
A fraction is a way to describe a part of a whole. The rate at which the farmer is harvesting his crop is 1.2 Acres/hour.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that the farmer can harvest 2/5 acre of the land in 1/3 hours, therefore, the area in which the farmer can harvest crops in 1 hour will be thrice 2/5.
[tex]\rm Rate\ of\ harvesting = \dfrac{\text{Total land harvested}}{\text{Total time taken by the farmer}}\\\\\\\rm Rate\ of\ harvesting = \dfrac{\frac25}{\frac13} = \dfrac{2 \times 3}{1 \times 5}\\\\\\\rm Rate\ of\ harvesting = \dfrac{6}{5}\ Acres/hour = 1.2 \ Acres/hour[/tex]
Hence, the rate at which the farmer is harvesting his crop is 1.2 Acres/hour.
