Answer:

218 ft²

Step-by-step explanation:

To solve, let's find the areas of the shapes that they give us.

Remember, the area of a  rectangle is length * height and the area of a triangle is base * height * 0.5

Area of 10 by 11 rectangle:

10 * 11 = 110

Area of triangle:

8 * 12 * 0.5 = 48

Area of 10 by 6 rectangle:

10 * 6 = 60

To find the area of the entire figure, add up these areas.

110 + 48 + 60 = 218

Thus, the area of the figure is 218 ft²

I hope this helps! Feel free to ask any questions!

Answer:  Srry if I'm wrong 252

Step-by-step explanation:

10 x 6= 60

8 x 12= 96

8 x 12= 96

10 x 11= 110

60 + 96 + 96 +110= 252.

Yolanda deposits $300 per month in an account with an APR of 6%, while Zach deposits $3600 at the end
bonufazy [111]

Answer:

Yolanda will have a balance of $34,043.10 in 14 years.

Step-by-step explanation:

This is an Ordinary annuity question where you pick the hint from the equal and recurring monthly payment.

To find the Future value of Yolanda's savings after 14 years, use Future value of annuity formula FVA = \frac{PMT}{r}[1-(1+r)^{-t} ]\\

PMT= recurring payment = $300

r = discount rate; monthly rate in this case = 6% / 12 =0.5% or 0.005 as a decimal.

t = total duration ; 14 *12 = 168 months

Next, plug in the numbers into the FVA formula;

FVA = \frac{300}{0.005} [ 1-(1+0.005)^{-168} ]

FVA = 60,000 * 0.5673849

FVA = 34,043.0969

Therefore, Yolanda will have a balance of $34,043.10 in 14 years

Find the exact length of the curve. x = 1 + 6t2, y = 4 + 4t3, 0 ≤ t ≤ 3
vovangra [49]

x=1+6t^2\implies\dfrac{\mathrm dx}{\mathrm dt}=12t

y=4+4t^3\implies\dfrac{\mathrm dy}{\mathrm dt}=12t^2

The length of the curve C is given by

\displaystyle\int_C\mathrm ds=\int_0^3\sqrt{\left(\frac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt

=\displaystyle\int_0^3\sqrt{144t^2+144t^4}\,\mathrm dt

=\displaystyle12\int_0^3t\sqrt{1+t^2}\,\mathrm dt

=\displaystyle6\int_0^3 2t\sqrt{1+t^2}\,\mathrm dt

=\displaystyle6\int_0^3\sqrt{1+t^2}\,\mathrm d(1+t^2)

=6\cdot\dfrac23(1+t^2)^{3/2}\bigg|_0^3

=4(10^{3/2}-1)

=40\sqrt{10}-4

Prove that DE is parallel to BC. <br> Please help, will award brainliest.
Gennadij [26K]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes.

To find D and E use the midpoint formula

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2}, \frac{y_{1}+y_{2}  }{2} )

Here (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(2, - 2) , then

D = (\frac{4+2}{2}, \frac{6-2}{2} ) = (3, 2 ) and

let (x₁, y₁ ) = B(2, - 2\frac{-4+2}{-2-2} ) and (x₂, y₂ ) = C(- 2, - 4 ), then

E = ( \frac{4-2}{2}, \frac{6-4}{2} ) = (1, 1 )

Use the slope formula to find slopes of DE and BC

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = D(3, 2) and (x₂, y₂ ) = E(1, 1), then

m_{DE} = \frac{1-2}{1-3} = \frac{-1}{-2} = \frac{1}{2}

Repeat with (x₁, y₁ ) = B(2, - 2) and (x₂, y₂ ) = C(- 2, - 4), then

m_{BC} = \frac{-4+2}{-2-2} = \frac{-2}{-4} = \frac{1}{2}

Since the slopes are equal then DE and BC are parallel lines
