Find the volume of the square pyramid below

Snowcat [4.5K]

Answer:

Step-by-step explanation:

The volume (V) of a pyramid is

V = $\frac{1}{3}$ area of base × perpendicular height (h)

area of square base = 4² = 16 and h = 4, hence

V = $\frac{1}{3}$ × 16 × 4 = $\frac{64}{3}$ = 21 $\frac{1}{3}$ ft³

The graph of a piecewise defined function is given. evaluate f(-2), f(0), f(1)

vfiekz [6]

Answer:

Step-by-step explanation:

because when x = -2 on the graph the y is -2 (-2,-2)

when the x values is 0 the y value is 1 (0,1)

and when x is 1 the y value is 2. (1,2)

hope this helps. have a good day

the vertices of ABC are points A(1,1), B(4,1), and C(4,5). find the cosines of the angles of the triangle.

pickupchik [31]

Answer:

cos(A) = 3/5
cos(B) = 0
cos(C) = 4/5

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between the cosine of an angle and the sides of the triangle.

Cos = Adjacent/Hypotenuse

<h3>Angle A</h3>

In the given triangle, the hypotenuse is AC. The side adjacent to angle A is AB, so its cosine is ...

cos(A) = AB/AC

cos(A) = 3/5

<h3>Angle B</h3>

The right angle in the triangle is angle B. The cosine of a right angle is 0.

cos(B) = 0

<h3>Angle C</h3>

The side adjacent to angle C is CB, so its cosine is ...

cos(C) = CB/AC

cos(C) = 4/5
