Answer:

D (last one), $x^2+y^2=45$

Step-by-step explanation:

We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}$

$d=3\sqrt{5}$

Since equation of circle is: $x^2+y^2=r^2$ we have to square the distance we just found, which gives us 45.

Answer:

x^2 + y^2 = 45

Step-by-step explanation:

(x − a ) ^2 + ( y − b ) ^2 =r^2

= (-3-0)^(2)+(6-0)^(2)

=45

Tell the maximum number of zeros that the polynomial function may have. then use descartes' rule of signs to determine how many

Marta_Voda [28]

F(x) = -4x^7 +x^3 -x^2 +5

a) It is a degree 7 polynomial, so will have 7 zeros (some may be repeated).

b) has 3 sign changes, so 1 or 3 positive real zeros. If odd powers have their signs reversed, the signs are changed to +--+, so there are 2 sign changes. There will be 0 or 2 negative real zeros.

____
There is actually 1 positive real zero and 0 negative real zeros. This means there are 3 conjugate pairs of complex zeros.

A cylinder is placed within a cube. The diameter of the cylinder is equal to the length of each side of the cube. What is the vo

pochemuha

The volume of a shape is the amount of space in it.

The volume outside the cylinder, but inside the cube is 214.6 cubic inches

The given parameter is:

$l = 10$ ---- length of the cube

So, the volume of the cube is:

$V_1 = l^3$

$V_1 = 10^3$

$V_1 = 1000$

The volume of the cylinder is:

$V_2 = \pi r^2h$

The diameter (d) of the cylinder equals the length of the cube.

This means that:

$d = l$

$d = 10$

Divide by 2 to calculate the radius of the cylinder

$r = \frac{10}{2}$

$r = 5$

Also, the height of the cube is::

$h =l$

$h =10$

So, we have:

$V_2 = \pi r^2h$

$V_2 = \pi \times 5^2 \times 10$

$V_2 = \pi \times 25 \times 10$

$V_2 = \pi \times 250$

$V_2 = 785.4$

So, the volume (V) outside the cylinder is:

$V = V_1 - V_2$

$V = 1000 - 785.4$

$V = 214.6$

Hence, the volume outside the cylinder is 214.6 cubic inches

The Math Club is sponsoring a bake sale. If their goal is to raise at least $300, how many pies must they sell at $6.00 each in

soldi70 [24.7K]

Given:
bake sale at least $300
price of each pie is $6.00
let the number of pies be represented by x.

Write the inequality:
6x > 300

Solve the inequality:
6x > 300
÷6 ÷6
x > 50

Graph the inequality.
y = 6x

x is the number of pies sold; x at least 50 and gradually increases.
y is the total sales
