1. A motorboat leaves a harbor and travels at an average speed of 15 mph toward an island. The average speed on the return trip

jenyasd209 [6]

Answer:

30 miles

Step-by-step explanation:

Let d represent the distance to the island. The relation between time, speed, and distance is ...

time = distance/speed

so the total time for the round trip is ...

d/15 +d/10 = 5

Multiplying by 30, we get

2d +3d = 150

d = 150/5 = 30

The island was 30 miles from the harbor.

-5(11-3t) = -6t - 4 what does t equal?

Inessa [10]

-5(11-3t) = -6t -4

distribute -5 to the parentheses

-55+15t = -6t -4

isolate t; add -6t from both sides

-55+21t = -4

add 55 from both sides

21t = 51

divide t

t = 2.4 (rounded)

Which function can be used to represent the graphed geometric sequence

11111nata11111 [884]

ANSWER

$f(x)=80( \frac{1}{4}) ^{x-1}$

EXPLANATION

The term of the sequence are;

$80,20,5,...$

The first term of the sequence is,

$a_1=80$

The common ratio is

$r = \frac{20}{80}$

$r = \frac{1}{4}$

The sequence is given by the formula

$f(x)=a_1r^{x-1}$

When we substitute the values into the formula we get,

$f(x)=80( \frac{1}{4}) ^{x-1}$

The correct answer is A
