Answer:
Step-by-step explanation:
Givem the profit function
p(x) = −2000x2 + 18000x − 15000
We are to generate the price range that will generate a monthly profit of at least $25,000
Substitute into the function we have;
25000 = −2000x2 + 18000x − 15000
Divide through by 1000
25 = -2x²+18x-15
Rearrange
-2x²+18x-15-25 = 0
2x²-18x+40 = 0
Divide through by 2
x²-9x+20 = 0
Factorize
x²-5x-4x+20 = 0
x(x-5)-4(x-5) = 0
x-4 = 0 and x-5 = 0
x = 4 and x = 5
Hence the price range that will generate a monthly profit of at least $25,000 is between $4 and $5 inclusive

whats the equation of the line shown below
Answer:
y = -3x + 3.
Step-by-step explanation:
The marked points on the line are (0, 3) and (1, 0) so:
the slope is (3 - 0) / (0 - 1) = -3.
The y-intercept is y = 3.
Therefore the equation of this line is y = -3x + 3.

Cost of boots: $99.99 Markup: 9% What is the new cost
Answer:
The new cost is $108.98
Step-by-step explanation:
Mark up is the amount that is added to cost price of a product for profit.
Given
Cost price of boots = C = $99.99
Mark up = 9%
First of all we will calculate markup and then add it to the cost price of boots to find the new cost.
[tex]Mark\ up = M = 9\%\ of\ 99.99\\= 0.09*99.99\\=\$8.99[/tex]
The new cost will be:
[tex]C_n = Cost\ price + mark\ up\\C_n = 99.99+8.99\\= 108.98[/tex]
The new cost is $108.98

1a. Write an equation to represent the following situation. The movie tickets cost $9 for adults (a) and $6 for children (c). The total cost was $132.
1b. If 10 children attended, how many adults were there?
2a. Write an equation to represent the following situation. A seventh grade class went on a field trip. 4 buses (b) and 3 vans (v) were used to take all 152 students.
2b. If vans carry 8 students each, how many students are on each bus?
Answer:
1a. 9a+6c=132
1b. There were 8 adults
2a. 4b+3v=152
2b. There are 32 students on each bus
Step-by-step explanation:
Answer:
1 a. $132= 9a + 6c
1b. 8 adults
2a. 152= 4b + 3v
2b. 32 students per bus
Step-by-step explanation:
1b. 132= 9a +60, so 132 subract 60 = 72, then divide by 9, so 72/9= 8 adults
2b. 152=4b + 24, so 152 subract 24 =128, then divide by 4, 128/4= 32 students per bus

Answer:
62
Step-by-step explanation:
180-56=124
124/2= 62
62+62+56=180
Answer:
x = 62 degrees
Step-by-step explanation:
This is an isosceles triangle from the two lines drawn. This means that the other angle is also x degrees.
we know a triangle is 180 degrees total and this triangle has a 56 degree for one angle and for the two other angles they have the same value.
This means
180 = 56 + x + x
180 = 56 + 2x
180-56 = 2x
124/2 = x
x = 62

A rotating sprinkler that sprays water at a radius of 11 feet is used to water a lawn. Determine the area of the lawn that is being watered. Use 3.14 for pi. Round to the nearest tenth.
Answer:
69.1²feet
Step-by-step explanation:
area = pi x r²
11x2= 22
22x 3.14 = 69.08
69.1
The area of the lawn that is being watered is, 380.1 feet².
What is area of circle?The area of a circle is π multiplied by the square of the radius. The area of a circle, (A) when the radius 'r' is given is πr2. π is approximately 3.142
here, we have,
area = pi x r²
so,
11^2= 121
121x 3.14
= 380.1
Hence, The area of the lawn that is being watered is, 380.1 feet².
