Answers

Answer 1
Answer:

Answer:

A. d = 59°

Step-by-step explanation:

We know that the 3 angles added up together are a straight line or 180°. Therefore,

m∠d° = 180 - (57 + 64)
Answer 2
Answer:

Answer: D. 59

Step-by-step explanation:

57 + 64 + d = 180°

121 + d = 180°

nicole and adam are each saving money for a car. the total amount of money nicole will save is represented by the function f(x)=36+4x. the total amount of money adam will save is represented by the function g(x)=x^2+15. after how many weeks, x, will they have the same amount of money saved? explain.

Answers

They will have the same amount of money after 7 weeks.

We first set these equal to each other:
36+4x=x²+15

We want to gather all of the variables on one side.  Subtract 4x from both sides:
36+4x-4x=x²+15-4x
36=x²-4x+15

We want the equation to be equal to 0 to solve it, so subtract 36 from both sides:
36-36=x²-4x+15-36
0=x²-4x-21

We can factor this expression.  We want factors of -21 that sum to -4; -7(3)=-21 and -7+3=-4:
0=(x-7)(x+3)

Using the zero product property, we know that x-7=0 or x+3=0; this means x=7 or x=-3.  Since a negative number of weeks makes no sense, the answer is 7 weeks.

Help D: An object is dropped from a small plane. As the object falls, its distance, d, above the ground after t seconds, is given by the formula d = –16t2 + 1,000. Which inequality can be used to find the interval of time taken by the object to reach the height greater than 300 feet above the ground?A.-16t^2+1000<300

B. -16t^2+1000<_ 300

C. -16t^2+1000>_300

D.-16t^2+1000>300

Answers

Answer:

D. -16t^2+1000>300 is the correct answer.

Step-by-step explanation:

It is given that Distance, d above ground  with time 't' is given by the formula:

d = -16t^2+1000

The negative sign with 16t^2 indicates that the distance is decreasing with square of time. i.e. value is getting subtracted from a value 1000.

For example, if t = 0, d = 1000 feet

If t = 2, d = -16* 4 + 1000 = 936 feet

We can clearly see that when 't' is increasing, the distance 'd' is decreasing.

And at a certain time, the object will be on ground when d = 0 feet.

Inequality for the distance greater than 300 feet i.e.

d > 300 feet

Hence, the inequality will be:

-16t^2+1000 >300  is the correct answer.
