Answer:

-2x +4

Step-by-step explanation:

We can write the polynomial p(x) in terms of the factors (x+2) and (x-3) as ...

p(x) = (x+2)(x-3)q(x) +ax +b

Where ax+b is the remainder from division by x^2 -x -6 = (x+2)(x-3). The values of 'a' and 'b' can be found from ...

p(-2) = 8 = -2a +b

p(3) = -2 = 3a +b

Subtracting the first equation from the second gives ...

(3a +b) -(-2a +b) = (-2) -(8)

5a = -10

a = -2

Then the first equation tells us ...

8 = -2(-2) +b

4 = b

So, the remainder from division by (x^2 -x -6) is (-2x +4).

A figure is composed of a semicircle and a right triangle. Determine the area of the shaded region. Use 3.14 for π and round to

Aliun [14]

Answer:

$A=9.5\ ft^2$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of triangle plus the area of semicircle

$A=\frac{1}{2}bh+\frac{1}{2}\pi r^{2}$

we have

$b=4\ ft$

Find the height of the right triangle applying the Pythagorean Theorem

$5^2=h^2+4^2$

$h^2=9\\h=3\ ft$

The radius of the semicircle is half the height of triangle

$r=3/2=1.5\ ft$

substitute in the formula

$A=\frac{1}{2}(4)(3)+\frac{1}{2}(3.14)(1.5)^{2}$

$A=6+3.5=9.5\ ft^2$

Write the equation in standard form 3x + 1 = 2y

yulyashka [42]

The standard form of an equation is
$ax + by = c$

In the question, we have the following formula
$3x + 1 = 2y$

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)
$3x - 2y + 1 = 0$

Finally we subtract 1 from both sides (since we need the number on the right side)
$3x - 2y = - 1$

Hence, 4. is the correct answer.
