Let's use a formula in order to find how much the interior angles are supposed to add up to.

(n-2)×180; n is the number of angles.

(5-2)×180= 3×180=540

We need for the interior angles to add up to 540. Let's make an equation.

100+102+108+121+x=540

431+x=540; let's find x.

540-431= 109

So, X= 109°

What’s the length of AZ. If A is between Y and Z, Y A = 22, AZ = 16x, and Y Z = 166

VLD [36.1K]

Answer:

c) 144

Step-by-step explanation:

Since A is between Y and Z,

$YZ = YA + AZ$

$116 = 22 + 16x\\16x = 116 - 22\\16x = 144\\x = 9$

however, the question asks for $the length of AZ$ , not the value of x.

Thus,

$AZ = 16x$

$AZ = 16\\$ × $9$

$AZ = 144$

Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)

Free_Kalibri [48]

Answer:

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$

Step-by-step explanation:

Let the equation of the give cubic function is,

f(x) = p(x - a)(x - b)(x - c)

Here, a, b, c and d are the x-intercepts of the given graph.

Since, x-intercepts given in the graph are x = -5, 1 and 4,

Equation of the curve will be,

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

Since, the graph of this function passes through (2, -2) also

-2 = p(2 + 5)(2 - 1)(2 - 4)

-2 = -p(14)

p = $\frac{2}{14}$

p = $\frac{1}{7}$

Therefore, equation will be,

f(x) = $\frac{1}{7}(x+5)(x-1)(x-4)$

Find the Area Of each circle.

Levart [38]

The area of the circle A and B is 86.54 inches and 124.62 mm

According to the statement

we have given that the radius of the circle A and b and we have to find the area of the given circle.

So, we know that the

The area enclosed by a circle of radius r is πr².

So, For area of the circle

For condition A :

diameter = 10.5 inches

then radius = 5.25

Area = πr²

Area = 3.14*27.56

Area = 86.54 inches

Now, For condition B :

radius = 6.3 mm

Area = πr²

Area = 3.14*39.69

Area = 124.62mm

So, The area of the circle A and B is 86.54 inches and 124.62 mm
