Answer:

QS = 16

Step-by-step explanation:

We can find QS by using the Pythagorean Theorem for Δ SQT

ST = 24/2 or 12

QT = 20

QS² + 12² = 20²

QS² + 124 = 400

QS² = 256

QS = √256, which is 16

Answer:

4

Step-by-step explanation:

x must equal 2 and 2 to the power of 2 is 4

Answer:

4

Step-by-step explanation:

Original equation: 3x-1=5

Add 1 on both sides: 3x=6

Divide by 3 on both sides: x=2

If x=2, then x^2 = 4.

Answer:

if i'm doing it right then sin p, but i'm not entirely sure...sorry

Step-by-step explanation:

Answer:

Cos P

Step-by-step explanation:

there's no way this can be sin so that cancels out to answers because this is a 90 60 30 triangle It can't be R because either way that's never going to equal Q

( maybe wait for second opinion)

Hope I helped!!

Answer:

x=−2 and y=−5

Step-by-step explanation:

Solve3x−2y=4for x:

3x−2y=4

3x−2y+2y=4+2y(Add 2y to both sides)

3x=2y+4

3x /3 = 2y+4 /3 (Divide both sides by 3)

x= 2 /3 y+ 4 /3

Substitute  2 /3 y+ 4 /3 for x in6x−2y=−2:

6x−2y=−2

6( 2 /3 y+ 4 /3 )−2y=−2

2y+8=−2(Simplify both sides of the equation)

2y+8+−8=−2+−8(Add -8 to both sides)

2y=−10

2y /2 = −10 /2 (Divide both sides by 2)

y=−5

Substitute−5 for y in x=

2 /3 y+ 4 /3 :

x= 2 /3 y+ 4 /3

x= 2 /3 (−5)+ 4 /3

x=−2(Simplify both sides of the equation)

Answer:

187 Books

Step-by-step explanation:

First you need to figure out the area of the closet. To do this you need to do 20 x 25 x 30 which equals 15,000. Then you should figure out the area of the books. To do this you would do 8 x 5 x 2 which equals 80. Then do 15,000 divided by 80 and you get 187.5 but you cant fit half a book in so then you round down and you get 187.

Answer:

[tex]y = 2 {(x - 3)}^{2} + 1[/tex]

Answer:

D) 2(x - 3)² + 1

Step-by-step explanation:

First off:

the equations are in y = a(x-h)²+k format.

So, that means that since the vtx is (3, 1), the answers could only be c or d

The difference between the two is one parabola is reflected (negative) and the other is facing up. Since (1, 9) is above the vtx, only D is the one that passes through (1, 9) because it is the only one facing upward to touch that point.
