Answer:

110.4622 = 110 (as followers cannot be in decimals).

Step-by-step explanation:

Given, growth rate is 1% = 0.01.

and it is for every 12 hours.

now, f(x) = f(1 + r)^t. where f= 100 (initial followers)

r = 0.01.

t =10 (1 for every 12 hours. so, 5 days = 120 hours = 10 times)

⇒ f(x) = 100(1+0.01)¹⁰ = 110.4622 = 110 followers.

D. $8,962.50

P stands for principal

R stands for rate

T stands for time

A=$7,500(1+ (0.039×5))=$8,962.5

A=$8,962.50

So Jake will have $8,962.50 of interest after 5 years.

PLEASEEE HELP !! What is the value of x ?

Shtirlitz [24]

Answer:

x = 20 cm

Step-by-step explanation:

The triangles given are similar triangles because they share the same angles. Because they are similar, their side lengths are in the same ratio, or proportion to one another. The left side of the larger triangle has a length of 121cm + 11cm = 132cm where the smaller triangle only has a length of 11 cm. We can put these lengths into a ratio:

$\frac{larger}{smaller}=\frac{132}{11}=\frac{12}{1}$
