I’d say D because 10 to the 5th power is 100000 and multiple by 8.2 makes 820000

Brian made a tasty burger. the diameter of the burger was 5cm. what was the area of burger
Vadim26 [7]
19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
                    =3.14 times 2.5 times 2.5
                    =19.625cm squared

I need help with number 10 please I’m so confused on how to do it!
Solnce55 [7]

Given:

A figure.

m \angle C D A=9 x+3 and m \angle E D A=6 x+5

To find:

What kind of figure and the value of x

Solution:

All four sides are congruent.

Diagonals bisect each other.

There the given figure is rhombus.

Diagonals bisect the angles.

⇒ m \angle C D A=m \angle E D A

9 x+3=6x+5

Subtract 3 on both sides.

9 x+3-3=6x+5-3

9 x=6x+2

Subtract 6x from both sides.

9 x-6x=6x+2-6x

3x=2

Divide by 3 on both sides.

$\frac{3x}{3} =\frac{2}{3} $

$x=\frac{2}{3} $

The value of x is \frac{2}{3}.

Find x in this 45°-45°-90° triangle.<br><br><br><br> x =
Zielflug [23.3K]
Use a^2 + b^2 = c^2

the triangle must be isosceles because the two angles are the same

1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706

Pls Help!!! Worth 99 Pts!!
Alenkasestr [34]
First, for end behavior, the highest power of x is x^3 and it is positive. So towards infinity, the graph will be positive, and towards negative infinity the graph will be negative (because this is a cubic graph)

To find the zeros, you set the equation equal to 0 and solve for x
x^3+2x^2-8x=0
x(x^2+2x-8)=0
x(x+4)(x-2)=0
x=0   x=-4   x=2

So the zeros are at 0, -4, and 2. Therefore, you can plot the points (0,0), (-4,0) and (2,0)

And we can plug values into the original that are between each of the zeros to see which intervals are positive or negative.
Plugging in a -5 gets us -35
-1 gets us 9
1 gets us -5 
3 gets us 21

So now you know end behavior, zeroes, and signs of intervals

Hope this helps<span />
