A couple wants to install a square mirror that has an area of 500 square inches.To the nearest tenth of an inch what length of wood trim is needed to go around the mirror

A couple wanted to install a square mirror that has:

Area of the mirror = 500 square inches.

x = nearest tenth of an inch , length of wood needed

s = sides of square

Area = s2

500 (area) = s2 | √

x = √500

=> √ 5 x 100

=> √ 5 x √100

=> 10 √ 5

=> approximately 22.4

Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4

:)

The answer is around 22.4 :) hope this helps!

given that sine theta = 0, and cosine theta is less than zero, find the exact values of the other two trig functions

Answer:

θ = π + periods of 2π

Sin (π + 2π) = 0

Cos (π + 2π) = -1

Tan (π + 2π) = 0

Step-by-step explanation:

Sin (θ)=0 implies that θ only can be 0 or π plus periods of 2π:

θ = 0+2π

θ = π+2π

For Cos(θ) the values only can be:

Cos (0+2π) = 1 and

Cos (π+2π) = -1

from this, only Cos (π+2π) < 0

So θ only can be θ=π+2π

Answer:

Below.

Step-by-step explanation:

The tangent is 0.

The secant is -1.

The cosecant and cotangent are undefined.

Paul graphe% the equatior y=6+x Which point does the graph not pass through? (0,6) (9,15) (6,12) (12,20)

You have to substitute the x points for x & the y points for y: (0,6) (9,15) (6,12) (12,20)

y = 6 + x

6 = 6 + 0

6 = 6

y = 6 + x

15 = 6 + 9

15 = 15

y = 6 + x

12 = 6 + 6

12 = 12

y = 6 + x

20 = 6 + 12

20 = 18

The point that does NOT pass through is (12,20).
