Nicole deposits $2,136 in a savings account paying 5.36% interest. To the nearest dollar, how much money does Nicole have in tot
jeka57 [31]

we know that


The simple interest formula is equal to


A=P(1+rt)


where


A is the Final Investment Value


P is the Principal amount of money to be invested


r is the rate of interest  

t is Number of Time Periods


in this problem we have


t=9\ years\\ P=\$2,136\\ A=?\\r=0.0536


substitute in the formula above


A=2,136(1+0.0536*9)


A=2,136(1.4824)

A=\$3,166.41  

Round to the nearest dollar

A=\$3,166  

therefore

<u>the answer is the option D</u>

\$3,166

Determine the number of x-intercepts that appear on a graph of each function. f (x) = (x - 6)2(x + 2)2
Tpy6a [65]
<span>The number of x-intercepts that appear on the graph of  the function
</span>f(x)=(x-6)^2(x+2)^2 is two (2): x=6 (multiplicity 2) and x=-2 (multiplicity 2)


Solution
x-intercepts:
f(x)=0→(x-6)^2 (x+2)^2 =0

Using that: If a . b =0→a=0 or b=0; with a=(x-6)^2 and b=(x+2)^2

(x-6)^2=0
Solving for x. Square root both sides of the equation:
sqrt[ (x-6)^2] = sqrt(0)→x-6=0
Adding 6 both sides of the equation:
x-6+6=0+6→x=6 Multiplicity 2

(x+2)^2=0
Solving for x. Square root both sides of the equation:
sqrt[ (x+2)^2] = sqrt(0)→x+2=0
Subtracting 2 both sides of the equation:
x+2-2=0-2→x=-2 Multiplicity 2
