Step-by-step explanation:

y and x are proportional:

y = kx

When x is 29, y is 275.5.

275.5 = 29k

k = 9.5

y = 9.5x.  When y is 408.5:

408.5 = 9.5x

x = 43

A relationship that can be modeled as a line that passes through the origin (y = kx) is a proportional relationship.

3. How much interest does $5300 earn at a rate of 2.8% interest compounded quarterly after 6
azamat

Answer:

The interest is I=\$74.46

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=6/12=0.5\ years\\ P=\$5,300\\ r=0.028\\n=4  

substitute in the formula above  

A=5,300(1+\frac{0.028{4})^{4*0.5}

A=5,300(1.007)^{2}  

A=\$5,374.46  

<em>Find the interest</em>

I=A-P

substitute

I=\$5,374.46-\$5,300=\$74.46

30 Use the method of completing the square to determine the vertex of f(x) = x² - 14x - 15.
agasfer [191]

Answer:

<h2>x² - 14x - 15 =  (x − 7)² − 64</h2><h2>Then the coordinates of the vertex are (7 , -64)</h2>

Step-by-step explanation:

x² - 14x - 15 = x² - 14x + (49 - 49) - 15

                  = (x² - 14x + 49) - 49 - 15

                  =  (x² - 14x + 7²) - 49 - 15

                  =  (x − 7)² − (49 + 15)

                  =  (x − 7)² − 64

x² - 14x - 15 =  (x − 7)² − 64

Then the coordinates of the vertex are (7 , -64)
