What is the measure of AC ? (First Picture)

kondaur [170]

Answer:

Part 1) $arc\ AC=33\°$

Part 2) $arc\ BC=130\°$

Step-by-step explanation:

Part 1) What is the measure of AC ?

we know that

The inscribed angle is half that of the arc it comprises.

so

$m$

substitute the values and solve for x

$2.5x+4=\frac{1}{2}(7x-2)$

$5x+8=(7x-2)$

$7x-5x=8+2$

$2x=10$

$x=5\°$

Find the measure of arc AC

$arc\ AC=7x-2=7(5)-2=33\°$

Part 2) What is the measure of BC ?

we know that

The inscribed angle is half that of the arc it comprises.

so

$m$

substitute the values

$65\°=\frac{1}{2}(arc\ BC)$

$2*65\°=(arc\ BC)$

$arc\ BC=130\°$

Choose the correct simplification of <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%5E5b%5E6%7D%7Ba%5E4b%5E4%7D%20%20" id="Tex

Rashid [163]

The correct simplification will be: (b) ab²

$\frac{a^5 b^6}{a^4 b^4}$

Here we will use the property of exponents for division of two exponential terms with same bases. The original property is : $\frac{x^m}{x^n} = x^m^-^n$

It means if the bases are same , then we will just subtract the exponents while dividing two terms.

Using this property:

$\frac{a^5}{a^4} = a^5^-^4 = a^1 = a$

and $\frac{b^6}{b^4} = b^6^-^4 = b^2$

So, $\frac{a^5 b^6}{a^4 b^4} = ab^2$

Write the equation in slope-intercept form<br><br> slope=5 and y-intercept is -6

4vir4ik [10]

Slope intercept form can be written as y = mx + b

m is the slope and b is the y-intercept

Your equation is y = 5x - 6
