Which is the correct calculation for the volume of the prism? A prism has a length of 6 units, height of 7 units, and width of 4

EastWind [94]

Answer: $V=168\ units^3$

Step-by-step explanation:

Given

Length of Prism $l=6\ units$

Height of prism $h=7\ units$

width of prism $b=4\ units$

Now Volume of a prism is given by

$V=l\times b \times h$

$V=6\times 4\times 7$

$V=168\ units^3$

What does it mean to be a factor of a polynomial

Leokris [45]

A factor of polynomial P(x) is any polynomial which divides evenly into P(x). For example, x + 2 is a factor of the polynomial x2 – 4. The factorization of a polynomial is its representation as a product its factors. For example, the factorization of x2 – 4 is (x – 2)(x + 2).

Identify holes in the graph of the function.

snow_lady [41]

Answer: x = 0

Step-by-step explanation:

The hole in the graph (a discontinuity) exist where the function doesn't exist. Because anything divided by zero is undefined, then the function would not exit at 0, thus having a hole/discontinuity.

Find the missing length indicated. x=

guapka [62]

Answer: x = 120

Step-by-step explanation:

Here we have 3 triangles, one big and two smaller ones, one at the left and other at the right.

Now, the right sides is shared by the right smaller triangle and the big triangle, if this length is Z, we have that (using the angle in top of it, A, such that 64 is adjacent to A.)

Cos(A) = 64/Z

Cos(A) = Z/(64 +225)

We can take the quotient of those two equations and get:

$1 = \frac{64*(64 + 225)}{Z^2} = \frac{18496}{Z^2}$

Then:

Z = √(18,496) = 136.

now, we have that for the smaller triangle one cathetus is equal to 64 and the hypotenuse is equal to 136.

Then, using the Pythagorean theorem:

64^2 + x^2 = 136^2

x = √(136^2 - 64^2) = 120
