The answer is 42

the equation x2-11+42 means that 7 and 6 added equal 11 but multiplied equal 42

So, I'm assuming that the x represents multiplication...
Because multiplication has a higher precedence over addition, we'll multiply the numbers first:
18 + 48
Then we simply add:
66

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include you

mote1985 [20]

Answer: a) The figure can be reasonably divided into two geometries:

• a rectangular prism

• a hemisphere.

b) The volume of the rectangular prism is given by

V = lwh

V = (10 cm)(5 cm)(4 cm) = 200 cm³

The volume of the hemisphere is given by

V = (2π/3)r³

V = (2π/3)(3 cm)³ = 18π cm³

c) The total volume of the figure is

total volume = (prism volume) + (hemisphere volume)

V = 200 cm³ + 18π cm³

V ≈ 256.549 cm³

Find the equation of the line.<br> Use exact numbers.

Citrus2011 [14]

Answer:

y = 4x + -9

Step-by-step explanation:

The y intercept which is -9, is the point in which the graph crosses the x-axis

In order to find the slope we need to identify two clear points on the graph.

- (0, -9)

- ( 1, -5)

Now that we have our two points we need to find the distance between them.

As you can see on the attachment the distance between the two points is 4 units up and 1 unit to the right, therefore the slope is 4/1 = 4.

Final Answer: y = 4x + -9
