Step-by-step explanation:
The exterior angles are ∠2, ∠3, ∠5 and ∠6.
What are exterior angles?Angles that are found outside or external to any geometric shape are called exterior angles.
They are also sometimes known as external angles or turning angle.
An exterior angle is made by extending one of the lines of the shape beyond the point of intersection.
Given is a figure, we need to find which of angles in the figure are exterior angles,
So, according to the definition of exterior angles,
The exterior angles are :-
∠2, ∠3, ∠5 and ∠6, because they are outside the figure as well as they are formed by the point of intersections.
Hence, the exterior angles are ∠2, ∠3, ∠5 and ∠6.

Answers
The solution for the equation 7x-4 = -18 is x = -2
The equation given is, 7x - 4 = -18.
We will try to solve this equation using elimination method in the following steps.
7x-4= -18
⇒ 7x-4+4 = -18+4
⇒7x = -14
⇒7x/7 = -14/7
⇒x = -2 is the solution for the given equation.
In the first step, we added 4 on both sides to eliminate -4 on the left side.
In the next step, we divided the both sides by 7 to eliminate the 7 on the left side. Finally, we got the solution as x = -2.

Use the inverse of the coefficient matrix to solve the system of equations.

2x+3y+4z = -10
−x−4y−8z = −66
Answers
Answer:
(x, y, z) = (-62, 50, -9)
Step-by-step explanation:
You want the solution to this system of equations using the inverse of the coefficient matrix.
x+2y+3z = 11
2x+3y+4z = -10
−x−4y−8z = −66
Inverse matrixThe inverse of the coefficient matrix is the transpose of the cofactor matrix, divided by the determinant. There are some shortcuts that can be used to make the computation easier. Easiest is letting a calculator find the matrix inverse. (See the first attachment.)
SolutionThe solution to the set of equations is the product of the inverse matrix and the constant vector on the right of the equal signs. That, too, can be found using a calculator. (See the second attachment.)
The solution is (x, y, z) = (-62, 50, -9).

According to the attached figure, the angle W is also corresponding, so in the triangle CEG one of the angles will be 14°
Angle Z
The sum of the interior angles of a triangle is 180°, so for triangle CEG:

Z + 14 + 78 = 180
Z = 88

Answers
The average rate of change of the given function f over the intervals-
f(x) = x²/8 ; x=a=1
the average rate of change of f(x) over the time interval [a, a + h] is
rc= [f(a +h) - f(a) ] / [(a +h)-a] = [(a +h)²/8 - a²/8] /h = 1/h [ (a²/8 +a*h/4+ h²/8) - a²/8]
= a /4+ h/8
then
rc= a/4+ h/8
for x=a=1 and h=1
rc= 1/4 + 1/8 = 0.375
for a=1 and h=0.1
rc= 1/4 + 0.1/8 = 0.2625
for a=1 and h=0.01
rc= 1 /4+ 0.01/8 = 0.25125
for a=1 and h=0.001
rc= 1/4 + 0.001/8 = 0.250125
for a=1 and h=0.0001
rc= 1 /4+ 0.0001/8 = 0.2500125
when h goes smaller , the average rate of change gets closer to the instantaneous rate of change of f(x) in x=a=1 (the derivative of f in a=1) , that is
