Answer 1

Answer:

Answer:

Step-by-step explanation:

1. f(-2) = 6 * 1/3^-2

f(-2) = 6 * 9

f(-2) = 54

2. y = -3 * 4^3

y = -3 x 64

y = -192

3. f(4) = 1/4 * 2^4

f(4) = 1/4 * 16

f(4) = 4

Let me know if I am right!

How do you do this ?

Answers

T is 71 degrees. We know this because the area of a triangle is 180 degrees, you add the angles given 27+82 which equals 109 then subtract that from 180 to find the missing angle “T” 180-109=71

Answer:

71 degrees

Step-by-step explanation:

The angles in a triangle add to 180 degrees, so

∠M + ∠A +∠T = 180

We know ∠M is 82 degrees, and ∠A is 27 degrees, so we can substitute them in.

82+27+∠T=180

109+ ∠T=180 Combine like terms by adding 82 and 27

109-109+ ∠T=180-109 Subtract 109 from both sides to get ∠T by itself

∠T=71

So, the m∠T is 71 degrees

What is 1/3 added to 1/4

Answers

If you would like to calculate 1/3 added to 1/4, you can do this using the following steps:

added to ... +
1/3 + 1/4 = 4/12 + 3/12 = (4 + 3) / 12 = 7/12

The correct result would be 7/12.

If you find a common denominator wich would be 12 then 1/3 turns to 4/12 and 1/4 turns into 3/12 youadd and its 7/12 and it cant be simplifed for the reason that 7 is a prime number
