Answer:

x = -1

y = 4

Step-by-step explanation:

i believe this shape is a rhombus because the diagonals are perpendicular and bisectors, meaning m∡A = m∡B = m∡C = m∡D

so AC = CB = BC = DA

y + 1 = 2y - 3

1 = y - 3

4 = y

Plugging in 4 for 'y' means all sides are equal to 5

find x: 2x + 7 = 5

2x = -2

x = -1

Integration of the following function

DerKrebs [107]

Answer: None of the above

Step-by-step explanation:

Given

$\frac{\mathrm{d} \bar{c}}{\mathrm{d} x}=-6x^{-2}+\frac{1}{6}$

$d\bar{c}=\left ( -6x^{-2}+\frac{1}{6}\right )dx$

Now, integrating both sides

$\int d\bar{c}=\int \left ( -6x^{-2}+\frac{1}{6}\right )dx$

$\bar{c}=-6\frac{x^{-2+1}}{-2+1}+\frac{1}{6}x+k_1$

$\bar{c}=6x^{-1}+\frac{1}{6}x+k_1$

What is the radius of a sphere if its surface area is 2,122.64 square inches? (Use 3.14 for .)

Lady_Fox [76]

$\bf \textit{surface area of a sphere}\\\\
SA=4\pi r^2~~
\begin{cases}
r=radius\\
------\\
SA=2122.64
\end{cases}\implies 2122.64=4\pi r^2
\\\\\\
\cfrac{2122.64}{4\pi }=r^2\implies \cfrac{530.66}{\pi }=r^2\implies \sqrt{\cfrac{530.66}{\pi }}=r$

HELP ASAP ILL GIVE YOU BRAINLEST

stellarik [79]

Answer:

f(x) = (8/3)x(x - 1).

Step-by-step explanation:

The vertex form of the function is

y = a(x - 1/2)^2 - 2/3 where a is some constant.

Now the roots are 0 and 1 so

For x = 0

0 = a(-1/2)^2 - 2/3

1/4 a = 2/3

a = 2/3 / 1/4 = 8/3.

So the function is

f(x) = (8/3)(x - 1/2)^2 - 2/3.

3 f(x) = 8(x - 1/2)^2 - 2

= 8(x^2 - x + 1/4) - 2

= 8x^2 - 8x + 2 - 2

3 f(x) = 8x(x - 1)

f(x) = (8/3)x(x - 1).
