Answer:

D

Step-by-step explanation:

7^-2 = 1/7^2

The negative means you flip it

1/7^2 times 7^6 is 7^6/7^2 (just multiply).

using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)

D is the only one that equals 7^4, as 2 times 2 is 4.

2. The acute angle below has a degree measurement that is one fifth of the degree measure of the obtuse
Ksenya-84 [330]

Answer:

Acute angle = 30°

Obtuse angle = 150°

Step-by-step explanation:

Method 1:

Let x represent the measurement of the obtuse angle

Obtuse angle = x

Acute angle = ⅕ of x = x/5

Thus:

x + x/5 = 180° (angels on a straight line)

Solve for x

(5x + x)/5 = 180

Multiply both sides by 5

5x + x = 180 × 5

6x = 900

x = 900/6

x = 150

Obtuse angle = 150°

Acute angle = x/5 = 150/5 = 30°

Method 2:

Since acute angle = ⅕ of the obtuse angle, therefore,

Obtuse angle = 5*acute angle

Let acute angle = x

Obtuse angle = 5x

Equation:

5x + x = 180° (angles on a straight line)

Solve for x

6x = 180

x = 180/6

x = 30

Acute angle = x = 30°

Obtuse angle = 5x = 5*30 = 150°

What is the rule for the sequence 3, 6, 18, 72, 360...?
Naddik [55]
You need to multiply another number each time.
For Example:
3x2=6
6x3=18
18x4=72
72x5=360
360x6= 2,160

It's a pattern

Evaluate the limit. lim x-positive infinity 8n^2 +5n +2/3+2n
Zolol [24]

Answer: 3

Step-by-step explanation:

So in summary, if the highest degree in the numerator and denominator equal, you can use the coefficients to determine the limit, if the highest degree in the numerator is larger than the highest degree of the denominator, the limit will be infinity.
