Answer:

(12^11)(19×7)

Step-by-step explanation:

12^13–12^12+12^11

(12^11)(12² - 12 + 1)

(12^11)(144 - 12 +1)

(12^11)(133)

(12^11)(19×7)

Therefore,

12^13–12^12+12^11 is a multiple of 19 and 7.

12^13–12^12+12^11 is divisible by 19 and 7.

A.) f(x) = x^2 because 2 > 1. So f(2) = 4.

A is correct.

B.) f(x) = x^2 because 5 > 1. So f(5) = 25.

B is incorrect.

C.) f(x) = 2x because -2 < 1. So f(-2) = -4.

C is incorrect.

D.) f(x) = 5 because x = 1.

D is correct.

So the answer is A and D.

5. Carla babysits and tutors to make extra money. She babysits for $5 an hour and tutors for $10 an hour.
HACTEHA [7]

Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

<h3>How to graph the inequality?</h3>

Let x represents hours babysitting and y represents hours tutoring

So, we have:

Earnings = Rate of babysitting * x + Rate of tutoring* y

This gives

Earnings = 5x + 10y

He wants to earn at least $95.

This means that:

5x + 10y ≥ 95

See attachment for the graph of the inequality

From the attached graph, two possible solutions are: (5, 7) and (8, 5.5)

This means that Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

Work out size of angle x
myrzilka [38]

Answer:

Step-by-step explanation:

Comment

You are given values for the adjacent side of <x and the hypotenuse of a right triangle. This defines the Cosine of an angle

Equation

Cos(x) = a/c the way you have labeled it.

Givens

a = 9

c = 18

Solution

Cos(x) = a / c

Cos(x) = 9 / 18

cos(x) = 1/2

x = cos-1(1/2)

x = 60 degrees

Answer

x = 60
