Cell Phone Towers
Towers
Assessment Practice
14. The table shows the number of cell phone towers a company will build
as the number of its customers increases.
PART A
is the relationship between number of towers and number of customers
proportional? Explain,
Customers
(thousands)
5.25
252
6.25
300
7.25
348
9.25
444
PART B
if there are 576 towers, how many customers does the company have?
Write a proportion you can use to solve.
1. The relationship between number of towers and number of customers is proportional.
2. When there are 576 towers, the number of customers that the company is 27648 customers.
How to calculate the value?From the information, the table shows the number of cell phone towers a company will build as the number of its customers increases.
When there are 5.25 towers, the customers are 252. This will be:.
= 252 / 5.25
= 48
Also, when it's 6.25, the customers are 300. This will be:
= 300/6.25
= 48
Therefore, there's a constant value of 48. This illustrates proportionality.
When there are 576 towers, the number of customers that the company have will be:
= 576 × 48
= 27648

Answer:
8.66
Step-by-step explanation:
You're solving for b.
first, use the formula
c = a^2 +b^2
b = c^2 -a^2 = 10^2 - 5^2 = 8.66025

Answer:
m = 21
Step-by-step explanation:
-5 = 2 - [tex]\frac{m}{3}[/tex]
Multiply both sides of the equation by 3.
-15 = 6 - m
Swap sides so that all variable terms are on the left hand side.
6 - m = -15
Subtract 6 from both sides.
-m = -15 - 6
Subtract 6 from −15 to get −21.
-m = -21
Multiply both sides by −1.
m = 21

Find the measures of two supplementary angleš if the difference between the
measures of the two angies is 35º
Answer:
<1 = 107.5 degrees
<2 = 72.5 degrees
Step-by-step explanation:
<1 = x
<2 = x -35
x + x - 35 = 180
2x = 180+35
x = 215/2
x = 107.5
<1 = 107.5
<2 = 72.5

Six times the quantity, x-2, is 24. Find the number
Answer:
x = 6
Step-by-step explanation:
it states 6 times the quantity x - 2, so the expression would be 6 ( x - 2 ) = 24. first multiply because you cannot add or subtract unlike terms. so 6 multiplied by x and -2, the expression would be (6x - 12) = 24. add 12 to 12 so you cancel the coefficient. but when adding to the constant add to the sum. now it is 6x = 36. since 6x is multiplication, divide 6x by 6 to isolate the variable, but divide the answer, 36 divided by 6 is 6. therefore x = 6. hope this helps

Determine the intercepts of the line
x intercept : ?,?
y intercept: ?,?
Answer:
x-intercept: 3 or (3,0)
y-intercept: -10 or (0,-10)
Step-by-step explanation:
1. The intercepts of a graph are points at which the graph intersects with the x - or y-axis.
2. Given the information above, the line intersects with the x-axis at (3,0) and the y-axis at (0,-10).
Therefore, the x-intercept is 3 or (3,0) and the y-intercept is -10 or (0,-10).

Divide 2y2 + 8 by 2y + 4. Which expression represents the quotient and remainder?
y – 2 –
y + 2 –
y + 2 +
y – 2 +
When 2(y^2) + 8 is divided by 2y + 4 is equal to (y - 2) + (16 / (2y + 4)). The expression represents the quotient is the 2y + 4. While the expression represent the remainder is 16 / (2y + 4). The remainder of the given expression can also be solve using the remainder theorem.
Answer:
We need to perform division of 2y2 + 8 by 2y + 4. To solve this problem, we need to use the long method of division such as shown below:
y - 2 r. 16
-----------------------
2y+4 √2y2 + 0y + 8
- (2y2 + 4y)
-----------------------
0y2 - 4y + 8
- (-4y -8)
-----------------------
0y + 16
The answer is y-2 + (16/(2y+4)) on which the remainder is 16 / (2y+4).

Which of following is the graph of y = -(x + 1)2 -3? o ty 2 ?? 덕 a -2 2 4 n DONE
Answer:
Neither of the graphs shown.
Step-by-step explanation:
Given the quadratic equation, y = - (x + 1)² - 3, where a = -1, and the vertex is the minimum value that occurs at point (-1, -3). It is easier to tell which graph corresponds to the given equation due to the coefficient, a. In quadratic fucntions, if a < 0, then it means that it is a downward-facing parabola. The value of a makes the parent function wider or narrower.
Also, the parabola is shifted 1 unit to the left, as defined by h = -1, and 3 units downward, defined by k = -3.
I'm not sure if there are other graphs as options. Since neither one of the graphs shown applies to the given quadratic equation, I'm including a screenshot of the correct graph for your reference, where it shows where the vertex is located, along with the y-intercept, (0, -4) -- just in case. Hopefully this helps.

CAN ANYBODY HELP ME What is the 100th term in the sequence beginning with -45, -43, -41, -39, ...?
Group of answer choices
153
150
155
200
55
Answer:
153
Step-by-step explanation:
Since the given sequence is arithmetic because it has common difference.
-43-(-45) ,= -43+45 = 2
-41+43 = 2
-39+41 = 2
Therefore, the common difference is 2.
General Term
[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]
Since we want to find the 100th term, substitute n = 100.
We know common difference which is 2 and defined as 'd'; substitute d = 2
a1 means first term so:-
[tex] \displaystyle \large{a_{100}= - 45 + (100 - 1)2} \\ \displaystyle \large{a_{100}= - 45 + (99)2} \\ \displaystyle \large{a_{100}= - 45 + 198} \\ \displaystyle \large{a_{100}= 153}[/tex]
what is the slope of the line whose equation is 13x+y-5=0?
Answer:
-13
Step-by-step explanation:
1. To find the slope, it'd be much to convert the line from standard form to slope-intercept form, meaning we have to solve for y. (y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.)
2. (Solving)
Step 1: Subtract 13x from both sides.
[tex]13x + y - 5 - 13x = 0 - 13x[/tex] [tex]y - 5 = -13x[/tex]Step 2: Add 5 to both sides.
[tex]y - 5 + 5 = -13x + 5[/tex] [tex]y = -13x + 5[/tex]3. As you can see, -13 is in the place of m, the slope.
Therefore, the slope of the equation 13x + y - 5 = 0 is -13.
