The closed bracket at 5 means there is a closed circle.

The fact it goes to negative infinity means the graph goes infinitely to the left.

Solve (x + 9)² = 25.

ollegr [7]

The answer is x = -4.
Applying the square root property of equality basically means that we need to take the square roots of both sides.

$\sqrt{(x+9)^{2} }= \sqrt{25}$

Which turns into: $x+9=5$

Then we can isolate x by subtracting 9 from both sides: $x=-4$

Calculate the volume of the cylinder. Use button, not 3.14. Round answer to the tenth place.

Volgvan

Answer:

68.69 m^3

Step-by-step explanation:

Volume of cone = $\frac{1}{3}\pi r^{2}h$

= $\frac{1}{3}\pi (2.9^{2})(7.8)$

= $\frac{1}{3}\pi (65.6)\\$

= $\frac{1}{3}(206)$

$= 68.69 m^3$

Aliun [14]

Answer:

(1): "*-5x2y" was replaced by "*(-5x2y)".

(2): "x2" was replaced by "x^2". 1 more similar replacement(s).

Equation at the end of step

2

:

3xy2 • -5x2y

STEP

3

:

Multiplying exponential expressions :

3.1 x1 multiplied by x2 = x(1 + 2) = x3

Multiplying exponential expressions :

3.2 y2 multiplied by y1 = y(2 + 1) = y3

I believe the answer is ( -3•5x3y3)
