BRAINLIEST!!! 2. Use the unit circle to find the value of cot (–90°).

Sholpan [36]

Answer:

cot(- 90)° = 0

Step-by-step explanation:

Using the identity

cot x = $\frac{cosx}{sinx}$ , then

cot(- 90)° = $\frac{cos(-90)}{sin(-90)}$ = $\frac{0}{-1}$ = 0

The function f(x)=−2(0.25)x+1 is shown. Select from the drop-down menus to correctly describe the end behavior of f(x).

Viktor [21]

Answer:

cos 59° = x/16

x = 16 cos 59°

x = 8.24

BC is given 23 mi

Maybe AB is needed

AB = √34² + 23² = 41 (rounded)

BC² = AB² - AC²

BC = √(37² - 12²) = 35

Let the angle is x

cos x = 19/20

x = arccos (19/20)

x = 18.2° (rounded)

Added point D and segments AD and DC to help with calculation

BC² = BD² + DC² = (AB + AD)² + DC²

Find the length of added red segments

AD = AC cos 65° = 14 cos 65° = 5.9

DC = AC sin 65° = 14 sin 65° = 12.7

Now we can find the value of BC

BC² = (19 + 5.9)² + 12.7²

BC = √781.3

BC = 28.0 yd

All calculations are rounded

The weight of water is 62 1/2 per cubic feet. Water that weighs 325 lbs will fill how many cubic feet

yulyashka [42]

Water that weighs 325 lbs will fill 5.2 cubic feet.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. The weight of water for 1 cubic feet is 62.5

2. The weight of water for 'X' cubic feet is 325

3. To find x, form an equation:

Cubic feet : Weight of water

1 : 62.5

X : 325

4. Cross multiply

X x 62.5 = 1 x 325

62.5X = 325

5. Make X the subject

X = $\frac{325}{62.5}$

6. Solve to find X

X = 5.2 cubic feet

Therefore, water that weighs 325 lbs will fill 5.2 cubic feet.
