Find the measure of the missing angles.

Karolina [17]

Answer:

angles b and c should be 153° each.

Step-by-step explanation:

We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°

How is an equation like an expression? How is it different?

morpeh [17]

Answer:

See explanation.

Step-by-step explanation:

An expression is a set of terms that are combined using addition, subtraction, multiplication, or division. The following are examples of expressions:

$2x-1$

$5y+8$

$2$

Note: expressions do not equal anything.

In contrast, equations are expressions that equal at least one term. The following are examples of equations:

$2y-4=26$

$4x-4=0$

$x=10$

$y=x+2$

Note: equations do equal a term, as shown in the examples.

A sheet of cardboard 12 inches square is used to make an open box by cutting out squares of equal size from the four corners and

GrogVix [38]

Answer:

$x=6+3\sqrt{2}$ is the size of the square

Step-by-step explanation:

Let the side of the square cut from the cardboard be “x”

Size of the square base = $12 -2x$ , height of the box = x

Volume of square box = Area * height = $(12-2x)^2 * x$

Differentiating the above equation and equating it to zero, we get –

d/dx $((12-2x)^2 * x)$

d/dx ${(144 + 4x^2 -48x)*x}$ = d/dx $(144x + 4x^3 -48x^2)$

d/dx $(144x + 4x^3 -48x^2) = 0$

$144+8x^2-96X= 0\\18 +X^2-12X = 0$

On solving above equation, we get –

$x=6+3\sqrt{2} \\ x=6-3\sqrt{2}$

Answer:

-3/4a^3b^2
3.2·10^-1
-0.1a^(n+1)

Step-by-step explanation:

To find the cube root, divide all of the exponents by 3. For a cube root, the sign is unchanged.

A) ∛(-27/64a^9b^6) = -∛(3^3/4^3·a^9·b^6) = -3/4a^3b^2

B) 9.6×10^-8 ÷ (3×10^-7) = (9.6/3)×10^(-8-(-7)) = 3.2×10^-1

C) ∛(-0.001a^(3n+3)) = -∛(0.1^3·a^(3n+3)) = -0.1a^(n+1)

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6

vodka [1.7K]

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial $-3x^4+2x^3-x^2+6$ through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial $-3x^4+2x^3-x^2+6$ .
