Step-by-step explanation:

The slope perpendicular to it is not defined as it goes infinitely in both sides and the slope parallel to it is 0

Answer:

Perpendicular slope: undefined

Parallel slope: zero

Step-by-step explanation:

y = -8 results in a horizontal line crossing -8 on the y-axis, with a slope of zero: 0/-8. A vertical line would be perpendicular and has an undefined slope because 0 is the denominator . A line parallel to y = -8 would be any line with a slope of zero and crosses the y-axis. Parallel lines have the same slope.

use the formula a=p(1+r/n)nt to find the compound interest account . zakk deposited $5600.0in an account which compounded 1.9%qu
Komok [63]

Answer:

A=\$6,768.75  

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=10\ years\\ P=\$5,600\\ r=0.019\\n=4  

substitute in the formula above  

A=\$5,600(1+\frac{0.019}{4})^{4*10}  

A=\$5,600(1.00475)^{40}=\$6,768.75

Can someone please answer this question I need it today please show work and please answer it correctly i
svlad2 [7]

Answer:

24) $495

25) 14%

26) 25/X = 83/100

27) 0.7p

28) x + .085x and 1.085x

29) $221.90

30) $24.10

31) $6.13

32) 40%

Step-by-step explanation:

24) 600 - (600 × 0.25) = 450

450 × 1.10 = 495

25) (106 - 93) ÷ 93 = 0.13978

0.13978 × 100 = 13.978 ~ 14

27) 1.0 - 0.3 = 0.7

28) 1.00 + 0.085 = 1.085

29) 100% - 15% = 85%

240 × 0.85 = 204

204 × 1.0875 = 221.85

30) 25.89 × 4 = 103.56

103.56 + 179.99 = 283.55

283.55 × 0.085 = 24.10175

31) 8.75 × 0.70 = 6.125

32) 80 - (80 × 0.40) = 48
