The volume of a solid right pyramid with a square base is V units3 and the length of the base edge is y units.
Evgen [1.6K]

Answer:

Height of the pyramid = 3v/y² units

Step-by-step explanation:

We are given;

- The volume of a solid right pyramid with a square base = v units³

- The length of the base edge = y units

The formula for volume of a pyramid is given as;

V = ⅓ x base area x height.

Since the base is square, we will use the formula for square area which is A = side × side.

Thus, v = ⅓ × (y × y) × height

Making height the subject, we have;

Height = 3v/y²

height of the pyramid would be given by the expression 3v/y² units

State the x- and y-intercepts of the line with the equation y= -2x+4
grandymaker [24]

Answer:

x-intercept: (2,0)

y-intercept: (0,4)

Step-by-step explanation:

x-intercept: when y = 0

y = -2x + 4

0 = -2x + 4

x = 2

y-intercept: when x = 0

y = -2x + 4

y = -2(0) + 4

y = 4

How do you find the x-intercepts if given the following polynomial in factored form?
elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

You know the intercepts occur at x = 0, so set each part of the factored form equal to zero and solve for x.

The first part, plain X = 0, so X = 0 is a root, an x-intercept

The second part (X-2)^2 = 0, so X = 2 is another root. Since the function is being squared, this root will happen twice. The function crosses this root twice.

The third part (x+4) = 0, so x = -4 is another root.

Finally, (x+1) so x = -1 is another root.

So you have X = 0, X = 2, X = -4, X = -1 as your x-intercepts

Pls help on this question ​
sveticcg [70]

Answer:

178.571429

Step-by-step explanation:

Area of square - 10*10 m = 100m

Area of the semicircle = Diameter = 10m, so the radius = 5m

Area of circle = \pi r^{2}

=> Area = 22/7 * 25

=> 78.5714286

Area of figure = 78.5714286 + 100 = 178.571429

Hope it helps :)
