Follow PEMDAS!
First E (exponent) so you'd do 2^2=4
Then S (subtract) so you'd do 3-4=-1
your answer is -1
f(2.5) means x is equal to 2.5.
Replace x in the equation with 2.5 and solve:
6(2.5) + 1.5 = 15 + 1.5 = 16.5
f(2.5) = 16.5
the answer is circle idk if it's right but it could be I'm in high school I've been through algebra 1 now in geometry
Answer:
8.245*10^6
Step-by-step explanation:
scientific notation is known as c*10^n
c : any number from 1-10
n : the power of base 10
the number in our case between 1 and 10 is 8.245
but then we want to move the decimal 6 spaces to the right, so we multiply that by 10^6
