Perpendicular lines, slope is opposite and reciprocal. so if the slope of line c is -4 then the slope of line d will be 1/4

Hope it helps

Find the amount A accumulated after investing $4800 for 17 years at an interest rate 6.2% compounded quarterly.

Nostrana [21]

Answer:

A = $13,660.81

Step-by-step explanation:

P (principal) = $4,800.00

I (interest) = $8,860.81

First, convert R as a percent to r as a decimal

r = R/100

r = 6.2/100

r = 0.062 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 4,800.00(1 + 0.062/4)(4)(17)

A = 4,800.00(1 + 0.0155)(68)

A = $13,660.81

16. Solve for the angle x.<br> cos(¹/2x) = ¹/2

Basile [38]

Answer:

We know that ,

$\rightarrow \tt \cos( \frac{\pi}{3} ) = \frac{1}{2}$

So ,

$\: \rightarrow \tt \cos( \frac{1}{2}x ) = \cos( \frac{\pi}{3} ) \\ \\ \rightarrow \tt \frac{1}{2}.x = \frac{\pi}{3} \\ \\ \rightarrow \tt x = \frac{2\pi}{3}$

we can add 2 pi to it since there will be no change in the value

Also,

$\: \rightarrow \tt \cos( \frac{14\pi}{6} ) = \frac{1}{2} \\ \\ \\ \rightarrow \tt \frac{1}{2} x = \frac{14\pi}{6} \\ \\ \rightarrow \tt x = \frac{7\pi}{3}$
