Answer:
(x -2)^2 + (y-6)^2 = 16
Step-by-step explanation:
The equation of a circle is of the form
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- 2)^2 + (y-6)^2 = 4^2
(x -2)^2 + (y-6)^2 = 16
Answer: 32
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
Perimeter = 2 * width + 2 * length
= 2*11 + 2(x + 5) = 50
2x + 10 + 22 = 50
2x = 50 - 10 - 22
2x = 18
x = 9

Answer:
- straight time: $699.20
- overtime: $165.60
- total pay: $864.80
Step-by-step explanation:
(a) Maria's straight time pay is ...
(38 h)×($18.40 /h) = $699.20
__
(b) Maria's overtime pay is ...
(6 h)×(1.5×$18.40 /h) = $165.60
__
(c) Her total pay is the sum of her straight time pay and her overtime pay:
$699.20 +165.60 = $864.80
Answer:
Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:
where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,
For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:
