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.

Answer:
C. on edge
Step-by-step
The graph that represents the function, based on the maximum and minimum values, and the period of the function, y = cos(4·x) is the option;
On a coordinate plane, a function has a maximum value at 1, and a minimum at negative 1. It completes one period at π/2. It crosses the x-axis at (0, 1)What is the period of a function?The period of a function is the length of the smallest interval over which the function repeats its values.
The function y = cos(4·x) has a maximum value of 1 and a minimum value of -1. '
The period of the function is; 2·π/|4| = π/2, which indicates that the function completes a cycle in an interval of π/2.
The function crosses the y-axis at x = 0, at which y = cos(4 × 0) = 1
The above information indicates that the graph that represents the function is the one that has a maximum of 1 and a minimum, of -1, completes a period at π/2, crosses the y-axis at (0, 1)
The correct option is therefore;
On a coordinate plane, a function has a maximum at 1, and minimum at negative 1. It completes one period at π/2. It crosses the y-axis at (0, 1)

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

Write an equation of a parabola in standard form that has a vertex of (-3,-4) and passes through (1,4)
As we know vertex -
[tex]y=a(x+3)^2-4[/tex]
Passes through (1,4). Substitute x = 1 and y = 4
[tex]4=a(1+3)^2-4\\4=a(4)^2-4\\4=16a-4\\4+4=16a\\16a=8\\a=\frac{8}{16}\\a=\frac{1}{2}[/tex]
Therefore the vertex equation is [tex]y=\frac{1}{2}(x+3)^2-4[/tex]
Since you want the "standard" form then..
[tex]y=\frac{1}{2}(x^2+6x+1)\\y=\frac{1}{2}x^2+3x+\frac{1}{2}[/tex]
So the standard form is 1/2x^2 + 3x + 1/2

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.

The cost of a compact disc is $18. Mrs. Meridth bought 3 discs and received a 15% discount. If the sales tax is 8.8%, find the total price. Show each step.
Answer:
$49.572
Step-by-step explanation:
Given that :
Cost per disc = $18
Number of disc purchased = 3
Discount received = 15%
Sales tax = 8%
Original cost : cost per dic * number purchased
Original cost = $18 * 3 = $54
Discounted price = (100 - 15)% * $54
Discounted price = $45.9
Sales tax :
(100 + 8)% of $45.9
108% * $45.9
= $49.572
Total price = $49.572
