A because -1/4x is your slope and the +5 would just be shifted over to the 5 on the y-axis

Answer: y = -1/4x +5 (option A)

Step-by-step explanation:

you should substitute the point in the equation so, you have to use "+c" instead of the "-3". the equation you have to use is y = -1/4x + c

(4,4)

y = -1/4x + c

4 = -1/4(4) + c

4 = -1 + c

4+1=c

c = 5

So the -3 in the equation should be replaced with 5 in the equation and that's the parallel line passing through the point (4,4)

therefore the equation is -   y = -1/4x +5

A person invests 10000 dollars in a bank. The bank pays 6.75% interest compounded monthly. To the nearest tenth of a year, how l
Savatey [412]

Answer: it will take 20.6 years

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $37900

P = $10000

r = 6.75% = 6.75/100 = 0.0675

n = 12 because it was compounded 12 times in a year.

Therefore,

37900 = 10000(1 + 0.065/12)^12 × t

37900/10000 = (1 + 0.00542)^12t

3.79 = (1.00542)^12t

Taking log of both sides, it becomes

Log 3.79 = 12t × log 1.00542

0.579 = 12t × 0.00234752004

0.579 = 0.02817t

t = 0.579/0.02817

t = 20.6 years

What is the area of this composite figure
zloy xaker [14]

Answer:

Area of Triangle = 1/2 bh

                    A = 1/2 (16 cm x 10 cm)

                   A = 160 cm2/2

                    A = 80 square cm

Area of Circle = \pid2/4

                  A = 3.14 x (16 cm)2 / 4

                  A = 3.14 x 256 cm2 / 4

                 A = 803.84 cm2 / 4

                 A = 200.96 cm2

        Area of Half Circle = 200.96 cm2 / 2

                 A = 100.48

Composite Figure = Area of Triangle + Area of half Circle

Area of Composite Figure = 80 cm2 + 100.48 cm2

Area of Composite Figure = 180.48 cm2
