Find the length of the base of a square pyramid if the volume is 128 cubic inches and has a height of 6 inches.

Alex777 [14]

$The\ value\ of\ the\ square\ pyramid:V=\dfrac{1}{3}BH\\\\B=128in^3;\ H=6in\\\\subtitute:\\\\\dfrac{1}{3}B\cdot6=128\\\\2B=128\ \ \ |divide\ both\ sides\ by\ 2\\\\B=64\ (in)\\\\a-the\ length\ of\ the\ base\\\\B=a^2\\\\a^2=64\to a=\sqrt{64}\to\boxed{a=8\ (in)}$

If $(2x+5)(x-3)=14$, find the sum of the possible values of $x$.

MA_775_DIABLO [31]

Answer:

x = 1/4 ± 1/4√233

Step-by-step explanation:

(2x + 5)(x - 3) = 14

~Use FOIL on the left side

2x² - 6x + 5x - 15 = 14

~Combine like terms

2x² - x - 15 = 14

~Subtract 14 to both sides

2x² - x - 29 = 0

~Use the quadratic formula and simplify

x = 1/4 ± 1/4√233

Best of Luck!

I'm really confused on this one please answer !!!!!!!

Sedbober [7]

The formula for finding the area of a rug: $A = s^2$

Plugging in the values we know, we can solve for s.

$79 = s^2$

Take the square root of both sides.

$\sqrt{79} = s$

$\sqrt{79}$ is approximately equal to 8.89

So, 8.89 feet is the answer.

If |u| = 10, |v| = 8, and the angle formed between them is 60°, then u · v = ?

Gre4nikov [31]

U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
