What is the measure of arc BD?

1 answer:

5 0

Since there is no specific situation or measurements for this, we just assume a circle with an arc BD. It has arbitrary values. In a circle, an arc can be measured by the measure of an arc. A measure of an arc is an angle that an arc makes at the center of a circle which it is a part. It has degrees units. It can be calculated when the length of an arc is given by using certain equations. The measure of an arc and the length of an arc always goes together.

Answer:

$3^64^{11}$

Step-by-step explanation:

It appears you're trying to simplify ...

$(3^{-2}4^{-5}5^0)^{-3}\cdot\dfrac{4^{-4}}{3^3}\cdot 3^3$

The final factor cancels the denominator of the fraction, so we have ...

$3^{(-2)(-3)}4^{(-5)(-3)-4}=3^64^{11}$

_____

The applicable rules of exponents are ...

(ab)^c = (a^c)(b^c)

(a^b)(a^c) = a^(b+c)

(a^b)^c = a^(bc)

Solve for x if 2(5x + 2)2 = 48

kicyunya [14]

x = 2

step 1 :

(2 • (5x + 2) • 2) - 48 = 0

step 2 :

4 • (5x + 2) - 48 = 0

Pulling out like terms :

20x - 40 = 20 • (x - 2)

step 4 :

20 • (x - 2) = 0

Equations which are never true :

Solve : 20 = 0

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

Solve : x-2 = 0

Add 2 to both sides of the equation :

x = 2

Answer:

g(-1) = 4

Step-by-step explanation:

Given:

g(x) = $\frac{3x^2 - 2x + 7}{2x + 5}$

To find g(-1), substitute x = -1

Thus:

g(-1) = $\frac{3(-1)^2 - 2(-1) + 7}{2(-1) + 5}$

g(-1) = $\frac{3 + 2 + 7}{-2 + 5}$

= $\frac{3 + 2 + 7}{-2 + 5}$

= $\frac{12}{3}$

g(-1) = 4
