The y intercept. Plz help I’m so confused and I may ask some questions later as long as I don’t have to pay. Thank you so much I

If you are trying to find the y intercept then you have already found it, it is 4. From that point you would then draw the rest of the slope.

Instead of drawing from (0,0) you would go up 4 units and then do rise over run (7/3) to plot your line.

7 times as much as the sum of 1_3 and 1_4

kherson [118]

If your underscores are supposed to be spaces, the verbal expression translates to 7(13 + 14).

This becomes 7(27) = 189

What annual rate of interest is required to triple an investment in 7 years if it were compounded quarterly?

Jobisdone [24]

Answer:

Option C) 16.01%

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

$t=7\ years\\P=\$x\\A=\$3x\\n=4$

substitute in the formula above

$3x=x(1+\frac{r}{4})^{4*7}$

$3=(1+\frac{r}{4})^{28}$

Apply log both sides

elevated both sides to 1/28

$\sqrt[28]{3}=(1+\frac{r}{4})$

Multiply by 4 both sides to remove fraction

$4\sqrt[28]{3}=4+r$

subtract 4 both sides

$r=4\sqrt[28]{3}-4$

$r=0.1601$

convert to percentage

$r=0.1601*100=16.01\%$
