f(x)=x^2-5x+6

↝ f(4) equals to substituting x = 4 in the equation.

Thus,

f(4)=4^2-5(4)+6\\f(4)=16-20+6\\f(4)=22-20\\f(4)=2

Therefore, f(4) = 2

Gianna put $1000 in a savings account for 18 months, The interest on the account is 3.5%. How much will Gianna earn in interest?
zimovet [89]

Answer:

amount of interest = 52.5

amount at the end of the period = 1052.5

Step-by-step explanation:

use the formula for simple interest

PRT/100

P is the principle

R is the rate of interest charged

T is the Time taken

18 months  = 1 years 6 months ( 1.5 years)

1000 * 3.5 * 1.5 = 5250

5250/100 = 52.5

the amount of interest = <u>52.5</u>

the amount she will have at the end of the period

= 1000 +52.5

= <u>1052.5</u>
