You invest $15,000 in a savings account with an annual interest rate of 2.5% in
almond37 [142]

Answer:

\$16,990.62  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=5\ years\\ P=\$15,000\\ r=2.5\%=2.5/100=0.025\\n=4  

substitute in the formula above

A=15,000(1+\frac{0.025}{4})^{4*5}  

A=15,000(1.00625)^{20}  

A=\$16,990.62

What is the vertex of the graph of the function below? <br><br>y = x2 + 8x + 12
Vera_Pavlovna [14]
Hello, 

The\,\,formula\,\,for\,\,the\,\,vertex\,\,of\,\,a\,\,quadratic\,\,equation\,\,is:  \\  V=( -\frac{b}{2a},f(-\frac{b}{2a}) )

That means that we must first obtain x, then we replace x in the function to get y, so:

x=- \frac{b}{2a}  \\  \\ x=- \frac{8}{2*(1)}  \\  \\ \boxed{x=-4} \\  \\ Reeplacing \,\,x: \\ y=(-4)^{2} +8*(-4)+12 \\ y=16-32+12 \\ \boxed{y=-4}

Answer: V=(-4 , -4)
