The amount a basketball coach spends at a sporting goods store depends on the number of basketballs the coach buys. The situation is represented by the function rule a= 13b.
Make a table of values and graph the function rule. Is the graph continuous or discrete? Explain.
Suppose the coach spent $117 before tax. How many basketballs did she buy?
Answers
The graph is discrete and the coach can buy 9 basketballs with $117.
What are Continuous and Discrete Functions?Continuous functions are those functions for which the value of function can take any number on a certain interval.
Discrete functions, on the other hand, takes separate and distinct values for the function.
The function here is,
a = 13 b
where a is the amount spending on the store and b is the number of basketball she buys.
(a) The table is shown below:
b : 0 1 2 3 4
a : 0 13 26 39 52
The graph is discrete because the function values are discrete.
(b) If the coach spent $117,
a = 117
b = a / 13
b = 117 / 13
b = 9
Hence the graph of the function is discrete and the coach can buy 9 basketballs with the given amount.

500 Bhadgaule caps bought for Rs. 200000 in Nepali market are sold in Britain after paying
5% export tax then 150% profit was made. Find the selling price of each Cap in Pound Sterling.
[£ 1 = Rs. 155.63]
Answers
Answer:
Selling price of each cap = £6.75 (Approx.)
Step-by-step explanation:
Given:
Number of caps = 500
Cost of caps = Rs. 200,000
Export tax = 5%
Profit = 150%
£ 1 = Rs. 155.63
Find:
Selling price of each cap
Computation:
Cost of 1 cap = 200,000 / 500
Cost of 1 cap = Rs 400
After Add export tax = 400 + 400(5%)
After Add export tax = Rs 420
After profit = 420 + 420(150%)
After profit = Rs 1050
Selling price of each cap = 1,050 / 155.63
Selling price of each cap = £6.75 (Approx.)

x = 120/29
Step-by-step explanation:
-1/6(x + 18) + 1/5(x + 5) = x - 6
-1/6x - 3 + 1/5x + 1 = x - 6
-1/6x + 1/5x + 1 - 3 = x - 6
-1/6x + 1/5x - 2 = x - 6
-5/30 + 6/30x = x - 6 + 2
1/30x = x - 4
1/30x - x = -4
-29/30x = -4
-29/30x • 30/29 = -4 • 30/29
-x = -4/1 • 30/29
-x = -120/29
-x/-1 = 120/29/-1

Meal tickets at a large school cafeteria cost $4 for children and $9 for adults. On a certain day,
if 14 times as many children's tickets were bought as adult meal tickets, and the total revenue
from selling all tickets was $2,584, about how many children bought meal tickets?
Answers
Answer:
Let's define:
C = number of children tickets bought
A = number of adult tickets bought.
We know that "On a certain day, if 14 times as many children's tickets were bought as adult meal tickets"
Then we have:
C = 14*A
And we also know that:
"the total revenue from selling all tickets was $2,584"
Then:
C*$4 + A*$9 = $2,584
Then we have a system of equations:
C = 14*A
C*$4 + A*$9 = $2,584
The first step to solve these is to isolate one of the variables in one of the equations, and then replacing it in the other equation. We can already see that C is already isolated in the first equation, then we can just replace it in the second one to get:
(14*A)*$4 + A*$9 = $2,584
A*$56 + A*$9 = $2,584
A*$65 = $2,584
A = $2,584/$65 = 39.75
Here we should have a whole number, (So one of the numbers given may be incorrect) This is because we can not have a 0.75 of a ticket sold.
In this case, we know that:
C = A*14
C = 39.75*14 = 546.5
We could round this up to get a whole number; 547
About 547 children tickets were sold.

Add 11 to both sides
[tex]3x-11+11>7x+9+11[/tex]

Subtract 7 from both sides

If $120.99 is charged for 654 units of electricity
used, find the cost of one unit of electricity,
plz help me solving this question step by step this is important for me
Answers
Answer:
The cost of one unit of electricity is $0.185
Step-by-step explanation:
Amount charged = $120.99
Units of electricity used = 654
The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.
So that,
cost of one unit of electricity = [tex]\frac{120.99}{654}[/tex]
= 0.185
cost of one unit of electricity = $0.185
This implies that the cost of electricity used is charged at $0.185 per unit.
Thus for 654 units of electricity used, the cost would be;
654 x $0.185 = $120.99

OA (2,00)
OB. (5,00)
OC. (-00, 2)

Answers
Answer:a
Step-by-step explanation:
The function h(x) is increasing on the interval (5, ∞).
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
The function h(x) = |x − 5| + 2 is increasing on an interval where the derivative is positive.
If x < 5, then h(x) = -(x-5) + 2 = 7-x, and if x > 5, then h(x) = x - 5 + 2 = x - 3. Thus,
h'(x) =[tex]\left \{ {{ -1, for x < 5} \atop { 1, for x > 5}} \right.[/tex]
Since h'(x) is positive for all x > 5, the function h(x) is increasing on the interval (5, ∞).

The reason for this is that they are a pair of vertical angles and so both of the angles will be the same.
As it's a circle and circles add up to 360 degrees, the other 2 angles would be 59 degrees each as 360-252 = 108 and 108/2 = 59 degrees. They are also vertical.

Step-by-step explanation:
Perimeter of the figure = sum of all its side lengths
Thus:
Perimeter = (x - 4) + (x + 3) + (x - 2) + x + (x + 1)
Perimeter = x - 4 + x + 3 + x - 2 + x + x + 1
Collect like terms
Perimeter = x + x + x + x + x - 4 + 3 - 2 + 1
Perimeter = 5x - 2
