Katherine invested $86,000 in an account paying an interest rate of 52%
earnstyle [38]

Answer: $4,331‬

Step-by-step explanation:

I will assume that the question meant 5.2% not 52% as this is quite excessive.

Katherine after 13 years.

Convert the variables;

n = 13 years = 13 * 365 = ‭4,745‬ days

r = 5.2% = 5.2/365 = 5.2/365%

Future value = P * ( 1 + r)^n

= 86,000 * (1 + 5.2/365%)⁴⁷⁴⁵

= $169,068

Michael after 13 years;

If compounded continuously, the formula is;

Future value = Pe^rt

= 86,000 * e⁰.⁰⁵ ˣ ¹³

= $164,737

Difference = 169,068 - 164,737

= $4,331‬

mylen [45]

in order to solve these equations, you need to divide the number by the varible. so #5 is 2.5y=5. you would divide 5 by 2.5, to get 2. the answer would be y=2

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Match the linear equations with their x-
jolli1 [7]

Answer:

Part 1) x-2y=2 ----> (2,0) and (0,-1)

Part 2) -3x+3y=7 ----> (-7/3,0) and (0,7/3)

Part 3) 7x-y=21 ----> (3,0) and (0,-21)

Part 4) 3x-5y=-20 ----> (-20/3,0) and (0,4)

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

The x-intercept is the value of x when the value of y is equal to zero

Part 1) we have

x-2y=2

1) <u><em>Find the x-intercept</em></u>

For y=0

x-2(0)=2\\x=2

the x-intercept is (2,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

0-2y=2\\y=-1

the y-intercept is (0,-1)

Part 2) we have

-3x+3y=7

1) <u><em>Find the x-intercept</em></u>

For y=0

-3x+3(0)=7\\x=-\frac{7}{3}

the x-intercept is (-7/3,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

-3(0)+3y=7\\y=\frac{7}{3}

the y-intercept is (0,7/3)

Part 3) we have

7x-y=21

1) <u><em>Find the x-intercept</em></u>

For y=0

7x-(0)=21\\x=3

the x-intercept is (3,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

7(0)-y=21\\y=-21

the y-intercept is (0,-21)

Part 4) we have

3x-5y=-20

1) <u><em>Find the x-intercept</em></u>

For y=0

3x-5(0)=-20\\x=-\frac{20}{3}

the x-intercept is (-20/3,0)

2) <u><em>Find the y-intercept</em></u>

For x=0

3(0)-5y=-20\\y=4

the y-intercept is (0,4)

Please help me with my work
vaieri [72.5K]
,so first split them into separate shapes (refer to pic) then calculate each one
I started with the triangle
8×6=48 and 48÷2=24 so the triangles area its 24
next the rectangle
12×8=96
and I did the triangle shape cut out of the square
4×3=12 12÷2=6 so its area is 6
and the squares area is 8×8=64
but u need to subtract 6 from 64 because that area is missing
then you get 64-6=58
then add all the areas
58+24+96 to get your answer of 178m
