The 7th term of the sequence to the nearest thousandth is 223.949

<h3>What are geometric sequences?</h3>

These are sequence that increases in an exponential form.

The formula for calculating the nth term of a geometric sequence is expressed as:

Tn = ar^n-1

Given the following parameters

a = 75

r = 1.2

n = 7

Substitute the given parameter into the formula

T7 = 75(1.2)^6
T7 = 223.949

Hence the 7th term of the sequence to the nearest thousandth is 223.949

Scilla [17]

Answer:

A. 8

Step-by-step explanation:

6.0061 x 10^7

/ = 6/8 x 10^7/10^6

7.8483 x 10^6

0.75 x 10^7-6

0.75 x 10^1

A: 0.75 = 7.5 = 8.

A ladder 15 feet long leans against the top of a structure at a 60 degree angle to the ground. What is the height of the buildin

Goshia [24]

Answer:

height of the building is 12.99 feet.

Step-by-step explanation:

given, try to analyse:

ladder 15 feet long.
60 degree angle to the ground.

the height of the building is opposite to the angle 60° and given hypotenuse, the ladder of 15 feet long.

using sine rule:

$sin(x) = \frac{opposite}{hypotenuse}$

$sin(60) = \frac{opposite}{15}$

$opposite = sin(60) *15$

$opposite = 12.99feet$

Therefore the height of the building is 12.99 feet.

18. Find the inverse of {(4, -1), (3, -2), (6, 9), (8, 5)}.

nadezda [96]

An inverse function will simply reverse the coordinate pairs of the original function. If f(x)=(x,y), f^-(x)=(y,x).

So 18 is H

...

If f(x)=y=3x-4, to find the inverse function, solve for x, and then reverse the labels as seen below...

y=3x-4

y+4=3x

(y+4)/3=x so the inverse function is:

y=(x+4)/3
