6 0

Answer:

D

Step-by-step explanation:

Using the sine ratio in the right triangle

noting that sin45° = \frac{1}{\sqrt{2} } ← exact value

sin45° = \frac{opposite}{hypotenuse} = \frac{8}{h}

Multiply both sides by h, then

h ×\frac{1}{\sqrt{2} } = 8

Multiply both sides by \sqrt{2}

h = 8\sqrt{2} → D

3) Solve the System of Equations using Elimination/Combinations. (5 points)
Schach [20]

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

- 2x - y = - 4 → (1)

x + 2y = 5 → (2)

Multiplying (2) by 2 and adding result to (1) will eliminate x- term

2x + 4y = 10 → (3)

Add (1) and (3) term by term to eliminate x

0 + 3y = 6

3y = 6 ( divide both sides by 3 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

x + 2(2) = 5

x + 4 = 5 ( subtract 4 from both sides )

x = 1

solution is (1, 2 )

What is the volume of a sphere with a diameter of 6 m, rounded to the nearest tenth of a cubic meter?
seraphim [82]

Answer:113 cubic meter

Step-by-step explanation:

Diameter=6

Radius=r=6/2

Radius=r=3

π=3.14

Volume of sphere=4/3 x π x r x r x r

Volume of sphere=4/3 x 3.14 x 3 x 3 x 3

Volume of sphere=(4x3.14x3x3x3) ➗ 3

Volume of sphere=339.12 ➗ 3

Volume of sphere=113.04

Volume of sphere =113 cubic meter

-8x times 5 to the power of 3 would equal -1000x right?
marusya05 [52]
No. If you write it out, it would be -8*5 which is -40. (-40)^3 is -64000. So your answer would be -64000x
