Find the vertex of the parabola.

1 answer:

Gnesinka [82]4 years ago

4 0

Answer:

The vertex is (3,4)

Step-by-step explanation:

f (x) = x^2 - 6 x + 13

Completing the square

-6/2 = -3 and squaring it = 9

= x^2 -6x +9 +4

= ( x-3) ^2 +4

The equation is now in vertex form

a( x-h) ^2 +k

where the vertex is ( h,k)

The vertex is (3,4)

How do you solve -10+2y=7

Eva8 [605]

Answer

y = $\frac{17}{2}$

Step-by-step explanation:

-10 + 2y = 7

Add 10 to both sides of the equation

2y = 7 + 10

Add 7 and 10

2y = 17

divide each term in 2y=17 by 2

$\frac{2y }{2} = \frac{17}{2}$

Divide y by 7

y = $\frac{17}{2}$

Beth will borrow $10,000 which earns 4% compound interest and she will repay that amount in 20 years. How much interest was earn

Serggg [28]

Answer:

$I=\$11,911.23$

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 amount that she will repay

P is the amount borrowed

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

$t=20\ years\\ P=\$10,000\\ r=0.04\\n=1$

substitute in the formula above

$A=10,000(1+\frac{0.04}{1})^{1*20}$

$A=10,000(1.04)^{20}$

$A=\$21,911.23$

Find out the interest

$I=A-P$

substitute the values

$I=\$21,911.23-\$10,000=\$11,911.23$
