Terry is trying to place a satellite dish on the roof of his house at the recommended height of 18 feet. His house is 32 feet wide, and the height of the roof can be described by the function below,where x is the distance along the width of the house. Where should Terry place the dish? h(x) = -3/2 | x - 16 | + 24 A: No place is high enough B: Right at top C: 12 or 20 feet from the edge D: 4 or 28 feet from the edge
Answer:
C: 12 or 20 feet from the edge
Step-by-step explanation:
We are told the recommended height is 18 feet and that the function describing the height is;
h(x) = -(3/2)|x - 16| + 24
This means that;
-(3/2)|x - 16| + 24 = 18
Multiply through by -2/3 to give;
|x - 16| + 24(-2/3) = 18(-2/3)
|x - 16| - 16 = -12
Add 16 to both sides to get;
|x - 16| = 16 - 12
|x - 16| = 4
Add 16 to both sides to get;
Expanding the absolute value problem, we have;
x - 16 = 4 or -(x - 16) = 4
Thus;
x = 16 + 4 or -x + 16 = 4
x = 20 or x = 16 - 4
x = 20 or x = 12
Since x is the distance along the width of the house, then Terry should place the dish 12 or 20 feet from the edge

a phone company advertises a new plan in which the customer pays a fixed amount of $25 per month for unlimited calls in the country and $0.10 per minute for international calls. if a costumer uses 65 international minutes, how much do they owe?
Answer:
$31.50
Step-by-step explanation:
To solve this problem, create the equation
y = 0.10x + 25
Where x is equal to the number of international minutes and y is equaled to the total price paid. Since we are give the number of international minutes (the x), plug this into the equation and solve for y.
y = 0.10(65) + 25
y = 6.5 + 25
y = 31.5 or $31.50
For how many different pairs of positive integers (a,b) with greatest common factor 1, and with a>b, does ab=30!
Answer:
4 pairs
Step-by-step explanation:
Given
ab = 30
Where
a > b
Required
Determine number of pairs (a,b)
To do this, we simply test values for a and b that satisfy the required condition.
First,
Take a = 30
Substitute 30 for a in ab = 30
30 * b = 30
b = 30/30
b = 1
The pair is (30,1)
Take a = 15
Substitute 15 for a in ab = 30
15 * b = 30
b = 30/15
b = 2
The pair is (15,2)
Take a = 10
Substitute 10 for a in ab = 30
10 * b = 30
b = 30/10
b = 3
The pair is (10,3)
Take a = 6
Substitute 6 for a in ab = 30
6 * b = 30
b = 30/6
b = 5
The pair is (6,5)
There exist no other pair that satisfy the given condition.
Counting the above pairs, there are just 4 pairs.
find the two angle measures from the diagram 3x+10 3x-28 there's 3 answer's 71,71 109 ,109 109,71 last question brainiest u will get
Answer:
109 and 71Step-by-step explanation:
3x + 10 + 3x - 28 = 180
6x = 180 - 10 + 28
x = 198/6
x = 33
substitute the value of x = 33 back into the equation to solve for each angle
= 3x + 10
= 3(33) + 10
= 109
= 3x - 28
= 3(33) - 28

What is the y intercept of the line represented by the equation
3x+2y = 6?
Answer:
3
Step-by-step explanation:
To identify the y-intercept represented by the given equation, we need to get the equation into slope-intercept from:
[tex]y=mx+b[/tex]
[tex]m=slope[/tex]
[tex]b=y-intercept[/tex]
Start with:
[tex]3x+2y=6[/tex]
Subtract [tex]3x[/tex] from both sides of the equation:
[tex]2y=-3x+6[/tex]
Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]2[/tex]:
[tex]y=-1.5x+3[/tex]
Identify the y-intercept:
[tex]b=3[/tex]

The numbers of copies of a college textbook sold quarterly over the past four years are: Since the time series has trend and seasonal pattern, to forecast the quarterly sales of the textbook, the following regression equation was found: stack y t with overparenthesis on top equals 2120 space minus 620 space Q t r 1 space minus space 1320 space Q t r 2 space plus space 290 space Q t r 3 space plus space 24 space t , where Q t r 1 , Q t r 2and Q t r 3 are dummy variables corresponding to Quarters 1, 2 and 3, and t = time period. The sales forecast for Quarter 3 of the next year is
Answer:
The predicted sales for the 4th quarter next year are 2168
Step-by-step explanation:
We formulate the given equation
Yt= 2120 - 620 Qtr 1 t -1320 Qtr 2 t + 290 Q tr3 t + 24 t
Taking the quarter 1 , 2 and 3 to be dummy variable the predicted sales for the 4th qtr are
Now put the values for the corresponding time period as 1,2 and 3
Yt= 2120 - 620 Qtr 1(0) -1320 Qtr 2(0) + 290 Q tr3 (0) + 24 (1)
Y(1)= 2120 + 24 = 2144 ( for year =1)
Y(2)= 2120+ 48= 2168 ( for year =2)
Y(3)= 2120 + 72= 2192 ( for year =3)
where t is the number of years.
So for the next year the fourth quarter sales are predicted to be 2168.
The sales forecast for Quarter 3 of the next year is 2192.
What is a sales forecast?It should be noted that a sales forecast simply means an expression for the expected sales revenue.
In this case, the sales forecast for Quarter 3 of the next year will be calculated thus:
= 2120 + 24(3)
= 2120 + 72
= 2192
Therefore, sales forecast for Quarter 3 of the next year is 2192.

Step-by-step explanation:
-4(x+6) + 2(x-2) First, distribute the -4 to x+6
-4x - 24 + 2(x-2) Now distribute the 2 into x-2
-4x - 24 + 2x - 4 Combine like terms
-4x + 2x - 24 - 4
-2x - 28 This might be your answer but if you are looking for what x is equal to then keep following along.
If you are solving for x then most likely the equation says that it is equal to zero
-2x - 28 = 0 Add 28 to both sides
-2x = 28 divide both sides by -2
x = -14
What is the area of a triangle if the top is 3 the left side is 6 and the right side is 6.7
the answer is 120.6 I'm pretty sure
Answer:
9.525 units squared
Step-by-step explanation:
I'm assuming the 3 is the base of the triangle so I split 3 in half and got 1.5 for 2 right triangles. I then did the area of a right triangle formula 1/2 base x height
1/2(1.5 x 6)=4.5
1/2(1.5 x 6.7) =5.025
Add these two together
5.025+4.5=9.525

Your friend says the absolute value equation |3x+8|-9=-5 has no solution because the constant on the right side of the equation is negative. Is your friend correct?
Make sure to show the work and solution the problem, as well as the explanation.
Answer:
No, ur friend is not correct
| 3x + 8 | - 9 = -5 You have to get the absolute value (and everything in it) on one side of the equal sign, and everything else on the other side. So we have to get that -9 across the equal sign by adding 9 to both sides.
| 3x + 8 } = -5 + 9
| 3x + 8 | = 4 So that number is not negative anymore.
now u can set up ur 2 equations and solve for x, your 2 equations would be:
3x + 8 = 4 and 3x + 8 = -4
** If that -9 would not have been there, then ur friend would have been correct.

In 1998, the population of country C was 38 million, and the exponential growth rate was 1% per year
Answer:
Step-by-step explanation:
Formula for the exponential graph is given by the function,
[tex]P(t) = P_0(1 + r)^t[/tex]
Where [tex]P(t)[/tex] = population after 't' years
[tex]P_0[/tex] = Initial population
r = rate of increase
t = Number of years
In 1988, population of a country C was 30 million.
A). Function for the population will be,
[tex]P(t)=38(1+0.01)^t[/tex]
[tex]=38(1.01)^t[/tex]
B). Population in year 2020,
[tex]P(22)=38(1.01)^{22}[/tex]
= 47.30 million
C). Doubling time means the duration in which [tex]P_0[/tex] becomes [tex]2(P_0)[/tex].
[tex]P(t)=2P_0[/tex]
[tex]2P_0=P_0(1.01)^t[/tex]
[tex](1.01)^t=2[/tex]
By taking log on both the sides of the equation,
t[log(1.01)] = log2
t = [tex]\frac{\text{log}(2)}{\text{log}(1.01)}[/tex]
= [tex]\frac{0.30103}{0.004321}[/tex]
t = 69.66 years

Answer:
the radius is 5 ft.
Step-by-step explanation:
radius = 1/2 diameter
10/2 = 5
R= 5
Answer: 5 feet
This one is easy. Because the radius of a circle (or a semicircle) is half of the diameter, you can simply divide the diameter by 2.
