H (t) = -t2 + t + 12 <br> Solve by using quadratic formula

Sedaia [141]

The quadratic formula is:

$x=\frac{-b+\sqrt{(b)^2-4(a)(c)}}{2a}$

and

$x=\frac{-b-\sqrt{(b)^2-4(a)(c)}}{2a}$

Let's identify our a, b, and c values:

a: -1

b: 1

c: 12

Plug in the values for a, b, and c into the equation. Let's do the first equation:

$x=\frac{-1+\sqrt{(1)^2-4(-1)(12)}}{2(-1)}$

Simplify everything in the radical:

$x=\frac{-1+\sqrt{49}}{-2}$

Simplify the radical:

$x=\frac{-1+7}{-2}$

Combine like terms:

$x=\frac{6}{-2}$

Simplify:

$x=-3$

This is one solution, now, let's solve for the other equation:

Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:

$x=\frac{-1-7}{-2}$

Combine like terms:

$x=\frac{-8}{-2}$

Simplify:

$x=4$

Your final answers are:

$x=-3$

$x=4$

Cos2a=1-2sin^2a for all values of a.

pickupchik [31]

$cos2a= cos^{2} a- sin^{2} a \\ but \ cos^{2} a + sin^{2} a=1 \\ i.e. \ cos^{2} a=1- sin^{2} a$
Therefore,
$cos2a=1- sin^{2} a- sin^{2} a \\ =1-2 sin^{2} a$

What is the volume of the cube when one side is 2 1/2 in

oksian1 [2.3K]

Answer:

15 5/8 in³ (=15.625 in³)

Step-by-step explanation:

recall

volume of cube = length ³

given length = 2 1/2 = 5/2 inches

volume of cube,

= (5/2) ³

= 5³ / 2³

= 125 / 8

= 15 5/8 in³
