Answer 1
Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40


1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

Which expression represents the series 1+5+25+125+625?

Answers

it is a geometric sequence
an=a1(r)^(n-1)
a1=first term
r=common ratio
n=which term
first term is 1
common ratio is 5
an=1(5)^(n-1)

that is the equatin/formulf for the nth term

if you want a summation formula of the sequence to the nth term
Sn=(a1(1-r^(n)))/(1-r)
in this case
Sn=(1(1-5^(n)))/(1-5) or
Sn=(1-5^(n))/(-4)
so in this case
up to 5th term

S5=(1-5^(5))/(-4)
S5=(1-3125)/(-4)
S5=(-3124)/(-4)
S5=781


anyway
a_(n)=(5)^(n-1) is the nth term
and
Sn=(1-5^(n))/(-4) is the summation up to the nth term


1(5)^0 + 1(5)^1 + 1(5)^2...

The expression representing the series would be

f(x) = 5^(x-1)

A banana bread recipe calls for 3/4 cup butter. One tablespoon equals 1/16 cup. How many tablespoons of butter are needed to make the banana bread?

Answers

Answer:

Banana recipe will require 12 table spoons of butter.

Step-by-step explanation:

Banana bread recipe requires the butter = (3)/(4) cups

Since (1)/(6) cup = 1 table spoon

Therefore, 1 cup = (1)/((1)/(16)) = 16 table spoons

Therefore, (3)/(4) cup of butter = (3)/(4)* 16

= 12 table spoons of butter

So Banana recipe will require 12 table spoons of butter.

3/4 of a cup is the same as 12/16 of a cup. if one tablespoon is 1/16 of a cup, then 12 tablespoons of butter are required
