Answers

Answer:

[tex]2x^8-6x^7+11x^6-2x+10[/tex]

If lines r and s are parallel, what would be the measurement of angle 6 if angle 1 was 2x+4 and angle 2 was 6x+8?

Answers

Answer: 134

Step-by-step explanation:

Angle 1 and 2 are supplementary and Angle 2 is congruent to Angle 6

Thus, first solve for x

8x+12=180

x = 21

Then solve for angle 2 which is congruent to angle 6

6(21) + 8 = 134

Find the area of this figure around your answer to the nearest 100. use 3.14 to approximate 3.14 as pi

Answers

Answer:

Area = 49.12 ft²

Step-by-step explanation:

The area of the figure = area of triangle + area of half of a circle

= ½*bh + ½(πr²)

b = 6 ft

h = 8 ft

r = ½ of 8 ft = 4 ft

π = 3.14

Plug in the values

Area of the figure = ½*6*8 + ½(3.14*4²)

Area = 24 + 25.12

Area = 49.12 ft²

Answer:

19 cm³

Step-by-step explanation:

The figure cam be decomposed into two cuboid.

✔️Dimension of cuboid 1:

L = 2 cm

W = 1 cm

H = 8 - 3 = 5 cm

Volume = L * W * H

Volume = 2*1*5 = 10 cm³

✔️Dimension of cuboid 2:

L = 3 cm

W = 1 cm

H = 3 cm

Volume = L*W*H = 3*1*3

Volume = 9 cm³

✅Volume of the irregular figure = 10 + 9 = 19 cm³

The population of a city has been increasing by 2% annually. In 2000, the population was 315,000. Predict the population of the city in 2020. Round your answer to the nearest thousand.​

Answers

Answer:

In 2020 there will be 468,073 people.

Step-by-step explanation:

Giving the following information:

Growth rate (g)= 2% = 0.02

Population 2,000= 315,000

Number of periods (n)= 20 years

To calculate the population in 2020, we need to use the following formula:

FV= PV*(1+g)^n

FV= 315,000*(1.02^20)

FV= 468,073

In 2020 there will be 468,073 people.
