Answer:

The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3

Step-by-step explanation:

Formula:

V=πr^2h

radius=2

height=15

V=π(2)^2*15

π(4)*15

4*15=60

60π

π=3.14

60(3.14)

188.4

Since its volume you have to cube it

188.4 cm^3

MrRissso [65]

Answer:

1. x=20 ; the angles are 90 degrees31 degrees 59 degrees

2. x=16; the angles are 16 degrees  92 degrees 72 degrees

Step-by-step explanation:

1. 180=90+31+(3x-1)

180-90-31=3x-1

59=3x-1

60=3x

x=20

plug in x for the third angle

2. 180= x+5x-8+3x+44

180=9x+36

180-36=9x

144=9x

x=16

plug in x to all the angles to find the real value

Which ordered pair does NOT lie on the graph of h(x)=-2x + 7
Rus_ich [418]

Answer:

A

Step-by-step explanation:

To determine if the ordered pairs lie on the graph, substitute the x- coordinate of the point into the equation and if the value agrees with the y- coordinate of the point then it lies on the graph

A

x = - 2 : y = -2(- 2) + 7 = 4 + 7 = 11 ≠ 3 ← (-2,3) not on graph

B

x = - 1 : y = - 2(- 1) + 7 = 2 + 7 = 9 ← (- 1, 9) lies on graph

C

x = 3 : y = -2(3) + 7 = - 6 + 7 = 1 ← (3, 1) lies on graph

D

x = 4 : y = - 2(4) + 7 = - 8 + 7 = - 1 ← (4, - 1) lies on graph

If the width of the garden is w, then the maximum area available is a square, giving you w² as the dimensions. So:
w²=-w²+28w
2w²=28w
w=14
The perimeter is 14 x 4, or 56 feet
