Answer:
a52=64.4
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =3.2 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
4.4-3.2 =1.2
d=1.2
n = the term number we are looking for
an = 3.2 +1 .2(n-1)
We are looking for the 52nd term so n=52
a52 = 3.2 +1 .2(52-1)
= 3.2 + 1.2(51)
= 3.2+61.2
= 64.4
B. 16=n*32; 50%
Step by step explanation:
16 divide 32= 1/2
1/2*100= 50
Answer: f(x)= 8
Step-by-step explanation:
First you would plug in F(3) into the equation
replace the x with a three
f(x)=2(3)+2
then multiply the 2 and 3 because when you see a number next to another number in parenthesis you multiply them
f(x)=6+2
Then lastly you would add the result of your multiplied numbers with the two which gives you f(x)=8.
<u>f(x)=8</u>
Answer:
4+5=9
27÷9=3
they sold 3 types of each because if you do 3×5=15 and 3×4=12 and add 12 and 15 you get 27.
