Draw a number line from –2 to 2. Put tick marks every one-tenth unit. Graph a point with the given coordinate.

1 answer:

7 0

Okay! I drew the graph and I got Point Q is 0.1 unit to the right of 1.

Knowing the order of the numbers is the best way to get the answer.

Answer:

± 60

Step-by-step explanation:

aₙ = a₁ * rⁿ⁻¹

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶ (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴ (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2 or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60

The ratios are Surface area ⇒ 4 : 25 Height ⇒ 2 : 5 and Volume ⇒ 8 : 125

<h3>How to determine the ratios?</h3>

The scale factor is given as:

m : n = 2 : 5

For the area, we take the square of the ratios.

i.e.

Area = 2^2 : 5^2

Evaluate

Area = 4 : 25

For the volume, we take the cube of the ratios.

i.e.

Volume = 2^3 : 5^3

Evaluate

Volume = 8 : 125

The given scale factor can be used for the height of the model and the original bicycle

Hence, the ratios are

Surface area ⇒ 4 : 25

Height ⇒ 2 : 5

Volume ⇒ 8 : 125
