Answer:

C

Step-by-step explanation:

in trangle NET the angles are 81 and  34 so the other angle must be 180-81-34=65, the other triangle has the same measurments for angles 81-34-65 so the triangles are similar because of AA similarity theorem

Can someone please answer this and explain it?

Answer:

Velocity = displacement / time

Distance = 3t^2 +2t +6 to find distance you need to plug in time = 2 sec

Distance = 3(2)^2 +2(2) +6

Distance = 3(4) +4 + 6

Distance = 12 + 4 +6

Distance = 22 meters

In this problem the displacement is the distance.

so

Velocity = 22 meters / 2 second

Velocity = 11 meters/second

Does this help?

Write in index form 12 × 12 × 12 × 12 × 12 × 12 × 12 × 12
iris [78.8K]

Answer:

\sf{12^{8} }

Step-by-step explanation:

12 × 12 × 12 × 12 × 12 × 12 × 12 × 12 = \sf{12^{8} }

\sf{12^{8} } = 429,981,696

An easy way to think of this is that there are 12 is being multiplied by itselg 8 times (there are 8 12s). Similar to how squared numbers work...

Hope this helps! If you need further explanation, let me know!

Find the area of a circle with a circumference of 6.28 units
viktelen [127]

Answer:

area of the circle = 3.14 square units

Step-by-step explanation:

Circumference of the circle formula is 2\pir

where r is the radius of the circle

given circumference = 6.28

2\pir = 6.28

Value of pi is 3.14

2*3.14 * r= 6.28

6.28 r = 6.28

divide by 6.28 on both sides

r = 1

radius = 1

Area of the circle = \pi r^2

= 3.14 *1*1 = 3.14
