lianna [129]

ANSWER

Period: 2π , amplitude: 4

EXPLANATION

The graphed function is

y =  4\cos(x)

The amplitude of this function is

|4|  = 4

The period is 2π because there is no phase shift hence the period is still equal to the parent function.

At another theater, workers have to cut a new trap door. The door can be no more than 137 square feet in area, with whole-number
otez555 [7]

Answer:

Step-by-step explanation:

Given:

trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long

⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in

⇒ 77inches by 105 inches

⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long

⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in

⇒ 160 inches by 92 inches

⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long

⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in

⇒ 66 inches by 148 inches

⇒ 9,768 square inches

130 square feet convert to square inches.

130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches

Perimeter = 2(160 + 117)

P = 2(277)

P = 554 inches

If h(x) = 5 + x and k(x) = StartFraction 1 Over x EndFraction, which expression is equivalent to (k circle h) (x)?
finlep [7]

Answer:A

Step-by-step explanation: to multiply fractions by a whole, you would set 5+x over 1, then you would have:

(5+x)/1 * 1/x

When multiplied, you get:

(5+x) * 1 / 1 * x

When you multiply anything by 1, it is just itself, so you end up with:

(5 + x) / x
