Answer:

4000

Step-by-step explanation:

A=P(2)^(t/d)

A=future amount

P=starting amount

t=time elapsed

h=doubling time

given

P=10^3

t=6

d=2

A=10^3(2)^(6/2)

A=10^3(2)^2

M<1 and m<2 are vertical angles if m<1 = 106° and M<2 equals 20x - 14 find M<2

Answers

Answer:

Answer:

m∠2= 86

Step-by-step explanation:

since they are vertical angles, that means they are both equal to eachother.

so lets set them equal!

17x+1=20x-14

17x+15=20x

15=3x

x=5

now input x into m∠2

m∠2 = 20(5) – 14 = 86

In the last 4 seasons, Luis scored 14,18, 15, and 25 goals. How many goals does he need to score this year, to end the season with an overall average of 20 goals per season? O A. 29 O B. 27 O C. 30 O D. 28​

Answers

Answer:

28

Step-by-step explanation:

For Luis to get a mean of 20 he would need:

14 + 18 + 15 + 25 + x (unknown number of goal he needs) / 5 = 20

Therefore 14 + 18 + 15 + 25 + x = 100

Solve for x to get 28

f varies inversely as the square of d. When d=2, f = 6. Find d when f is 1.5

Answers

Answer:

d = 4

Step-by-step explanation:

Given f varies inversely as d² then the equation relating them is

f = [tex]\frac{k}{d^2}[/tex] ← k is the constant of variation

To find k use the condition when d = 2, f = 6 , then

6 = [tex]\frac{k}{2^2}[/tex] = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

24 = k

f = [tex]\frac{24}{d^2}[/tex] ← equation of variation

When f = 1.5 , then

1.5 = [tex]\frac{24}{d^2}[/tex] ( multiply both sides by d² )

1.5d² = 24 ( divide both sides by 1.5 )

d² = 16 ( take the square root of both sides )

d = [tex]\sqrt{16}[/tex] = 4

What is the area of the trapezoid?
9 yd
8 yd
13 yd

Answers

Answer:

area = 88 yd²

Step-by-step explanation:

area = 1/2(b1 + b2)h = 1/2(9 + 13)(8) = 88 yd²

Answer:

88 yd^2.

Step-by-step explanation:

Area of a trapezoid = 1/2 * h * (a + b) where h = height, a and b are lengths of 2 parallel side.

Area = 1/2 * 8(9+13)

= 4 * 22

= 88 yd^2.

Answers

Answer:

y - 9 = -3/2 (x - 6)

Step-by-step explanation:

Equation of line: 4x - 6y - 15 = 0

Equation of perpendicular line: bx - ay + k = 0

                                                 = -6x - 4y + k = 0 → (equation 1)

Since the equation passes through (6,9)

-6(6) - 4(9) + k = 0

-36 -36 + k = 0

-72 + k = 0

k = 72

Substituting the value of in equation 1,

∴ Equation of perpendicular line = -6x -4y + 72 = 0

dividing by -2,

3x + 2y - 36 = 0

This equation is the simplified version of Option 1.

                                                   

y - 9 = -3/2 (x - 6)

y - 9 = (-3x + 18)/2

2y - 18 = -3x + 18

3x + 2y - 36 = 0

Question 2 is b i think

I honestly have no clue how to do this

Answers

Answer:

Angle 1: 95 degrees

Angle 2: 85 degrees

Angle 3: 95 degrees

Step-by-step explanation:

Vertical angles are opposite and equal so in this case angle 1 and 3 are vertical and so are 2 and 85°

So that means angle 2 also equals 85 degrees and because of supplementary angles the other angle must add up to equal 180 degrees

85 + ? = 180

?=95

So both angle 1 and 3 equal 95 degrees
