Solve the equation by factoring. z2 − 6z − 27 = 0

1 answer:

7 0

The answer is x= 9 and -3

You must fine 2 number that multiply to equal -27 and add to equal -6

(x-9) (x+3)
Then equal the parts of the binomial to zero

x - 9 = 0
x + 3 = 0

You must get x by its self.
When you do so, you'll have the answer as -3 and 9

HELP PLS!!!!!! Select the correct location on the number line.

Elza [17]

Answer:

Point E on the number line represents the approximate volume of a cylinder with a radius of 4 units and height of 4 units.

Step-by-step explanation:

It is given that the radius of the cylinder is 4 units and the height of the cylinder is 4 units.

The volume of the cylinder is

$v = \pi \: r {}^{2} h$

Where, r is radius and h is height of the cylinder.

Substitute r=4, h=4, π=3.14 in the above formula.

$v = (3.14)(4) {}^{2} (4)$

$v = 200.96$

The volume of the cylinder is 200.96. Therefore, point E on the number line represents the approximate volume of a cylinder with a radius of 4 units and height of 4 units.

What is the height of the beach sign?

bagirrra123 [75]

To find the height of this umbrella you need to use the tangent function.

$tan 45 = \frac{8}{x}$
$(tan 45)(x) = 8
$
$x = \frac{8}{tan 45}$
$x = \frac{8}{1}$
$x = 8$

The height of the umbrella is 8.

Hope this helps :)
