Answer:

arc BC = 140

Step-by-step explanation:

Comment

Pick a point inside the circle. It should look like this point is the center of the circle. Call this point D. Draw lines CD and BD

CD makes a right angle with AC

BD makes a right angle with AB

The central angle formed by The given information above is

<BDC = 360 - 90 - 90 - 40

<BDC = 140.

Answer The arc measurement of BC = 140

What is the value of x? 3x + (6x - 6) = 4(2x-2)

olya-2409 [2.1K]

Answer:

x = -2

Step-by-step explanation:

To start, let's add on the first side to get 3x + 6x - 6 = 9x - 6. For the second side, we need to distribute the 4 to get 4(2x) + 4(-2), or 8x + (-8) or 8x - 8. Setting these equal, we subtract 8x from both sides to get x - 6 = -8, and adding 6 to both sides gives x = -2.

Find a degree 4 polynomial having zeros -8,-1,4 and 5 and the coefficient of x^4 equal 1.

Keith_Richards [23]

Answer:

x^4 -53x^2 +108x +160

Step-by-step explanation:

If a is a zero, then (x-a) is a factor. For the given zeros, the factors are ...

p(x) = (x +8)(x +1)(x -4)(x -5)

Multiplying these out gives the polynomial in standard form.

= (x^2 +9x +8)(x^2 -9x +20)

We note that these factors have a sum and difference with the same pair of values, x^2 and 9x. We can use the special form for the product of these to simplify our working out.

= (x^2 +9x)(x^2 -9x) +20(x^2 +9x) +8(x^2 -9x) +8(20)

= x^4 -81x^2 +20x^2 +180x +8x^2 -72x +160

p(x) = x^4 -53x^2 +108x +160

_____

The graph shows this polynomial has the required zeros.

Which of the following expressions are equivalent to - -a/b

riadik2000 [5.3K]

Answer:

B) $-\frac{a}{-b}$

Step-by-step explanation:

1. First, we have to know that two negatives equal positive.

2. Given the information above, $-\frac{-a}{b}$ can simplify to $\frac{a}{b}$ .

3. Let's go through each answer choice and see which one also simplifies to $\frac{a}{b}$ .

$\frac{a}{-b}$
$-\frac{a}{b}$

$-\frac{a}{-b}$
$\frac{a}{b}$

Therefore, the answer is B) $-\frac{a}{-b}$ .
