Help pls this geometry killing me??!!!

kondaur [170]

Answer:

Step-by-step explanation:

The triangle AEC is a right triangle and 2 sides are already filled in.

The hypotenuse is 10 and one side is 6.

So, this is a 3-4-5 right triangle.

Thus, the remaining side EC is 8.

Since EC is congruent to ED, then segment CD is 8+8=16

Given: Right triangles CES and RST. In two or more complete sentences, explain what additional information is needed to prove tr

masya89 [10]

You know one angle is 90 degrees because they are right triangles. In order to prove CES congruent to RST, you would need two legs, three angles, or a leg and an included angle.

For the funtion f(x)= (x+7)^5, Find f^-1 (x)

quester [9]

Answer:

The inverse of function $f(x)= (x+7)^5$ is $\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}$

Option A is correct option.

Step-by-step explanation:

For the function $f(x)= (x+7)^5$ , Find $f^{-1} (x)$

For finding inverse of x,

First let:

$y=(x+7)^5$

Now replace x with y and y with x

$x=(y+7)^5$

Now, solve for y

Taking 5th square root on both sides

$\sqrt[5]{x}=\sqrt[5]{(y+7)^5}\\\sqrt[5]{x}=y+7\\=> y+7=\sqrt[5]{x}\\y=\sqrt[5]{x}-7$

Now, replace y with $f^{-1} (x)$

$f^{-1} (x)=\sqrt[5]{x}+7$

So, the inverse of function $f(x)= (x+7)^5$ is $\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}$

Option A is correct option.

Find the volume of each sphere 40mm

Anastasy [175]

The formula for finding the volume of a sphere is $V=\frac{4}{3} \pi r^3$

If 40mm is the radius of the sphere, the volume will be about $2.68\times10^5$ mm.
