The instantaneous rate of change in the percent of households that used the internet for electronic banking in the year 2000 is; 6.8%
How to find the instantaneous rate of change?Formula for instantaneous rate of change is;
f'(x) = (f(b) - f(a))/(b - a)
From the table showing the the percent of households that used the internet for electronic banking in the year 2000, we can find the instantaneous rate of change as;
f'(2000) = (f(2001) - f(1999)]/(2001 - 1999)
f'(2000) = (21.6 - 8)/(2001 - 1999)
f'(2000) = 13.6/2
f'(2000) = 6.8

Solve for x in the equation below.

x-6 = 7
e
Answer:
x=13
Step-by-step explanation:
Given the following: f(x) = 3x - 7; g(x) = 13- 2x; and h(x) = 6x
h(g(g(x))) equals 13æ - 9.
True
False
We will see that:
h(g(g(x)) = -78 + 24x
Which means that the statement is false.
Is the statement true?
Here we have that:
g(x) = 13 - 2x
h(x) = 6x
Now we want to find the composition of functions:
h(g(g(x))
First, let's find g(g(x)) = 13 - 2*g(x) = 13 - 2*(13 - 2x) = 13 - 26 + 4x
g(g(x)) = -13 + 4x
Now let's evaluate h(x) in that:
h(g(g(x)) = 6*g(g(x)) = 6*(-13 + 4x) = -78 + 24x
This is not equal to what we have in the question, so we conclude that the statement is false.

If sis equal to 16,c is equal to 14m and b is equal to 19m ,find the angles of 5he triangle ABC with following work steps
Answer:
Below in bold.
Step-by-step explanation:
a = 16, b = 19 and c = 14.
By the Cosine Rule:
cos A = (a^2 - b^2 - c^2) / -2bc, so:
cos A = ( 16^2 - 19^2 - 14^2) / (-2*19*14)
= -301 / - 532
= 0.565789
m < A = 55.54 degrees.
Now Using the Sine Rule:
a / sin A = b / sin B
16 / sin 55.54 = 19/sin B
sin B = 19 * sin 55.54 / 16
= 15.666 / 16
= 0.979125
m < B = 78.27 degrees.
Finally
m < C = 180 - 55.54 - 78.27 = 46.19 degrees.

if the roots of the polynomial function are -9 and 7 - i, then the other factor of the polynomial function is x - (7 + i)
How to determine the other factor?The roots of the polynomial function are given as:
-9 and 7 - i
The root is 7 - i is a complex number.
This means that its conjugate must also be a root of the factor.
The conjugate of 7 - i is 7 + i
So, we have:
x = 7 + i
Equate to 0
x - (7 + i) = 0
Hence, the other factor of the function is x - (7 + i)

What is
-7+13+8X -2
Please help meee step by step
Answer:
-1/2 = x
OR
-0.5 = x
Step-by-step explanation:
1) Isolate x from the equation by making it equal to zero
(Reminder that everything crossing over to the other side of the equation changes it's symbols from positive to negative, and vice-versa is the original symbol was negative)
-7 + 13 + 8x - 2 = 0
-7 + 13 - 2 = -8x
2) Add up common terms on the left side
-9 + 13 = -8x
4 = -8x
3) Divide the entire equation by the number that would leave "x" by itself the factor or number that leaves the number by itself is negative eight since its the number with the equation (-8)
4/-8 = -8x/-8
-1/2 = x
OR

Answer:
∠ FLW = 112°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FLW is an exterior angle of the triangle , then
∠ FLW = x + 32 , that is
2x - 48 = x + 32 ( subtract x from both sides )
x - 48 = 32 ( add 32 to both sides )
x = 80
Then
∠ FLW = 2x - 48 = 2(80) - 48 = 160 - 48 = 112°

If m8=23, find each measure. Give your reasoning
The measure of each angle and their reasoning are explained for all in the explanation below.
We are given that;
m∠8=23°
a). From the given image, we see that;
m∠1 and m∠8 are supplementary angles and as such they sum up to 180°;
Thus; m∠1 + m∠8 = 180°
m∠1 = 180° - m∠8
m∠1 = 180 - 23
m∠1 = 157°
b). We see that m∠1 and m∠2 are angles that form a straight line.
Sum of angles on a straight line equals 180°. Thus;
m∠1 + m∠2 = 180°
m∠2 = 180 - 157
m∠2 = 23°
c). We see that m∠3 and m∠1 are vertically opposite angles and they must be equal. Thus
m∠3 = m∠1
Thus; m∠3 = 153°
d). We see that m∠4 and m∠2 are vertically opposite angles and they must be equal. Thus
m∠4 = m∠2
Thus; m∠4 = 23°
e). We see that m∠5 and m∠1 are corresponding angles and are therefore equal. Thus;
m∠5 = m∠1
m∠5 = 157°
f). We see that m∠6 and m∠8 are vertically opposite angles and as such;
m∠6 = m∠8
Thus, m∠6 = 23°
g). We see that m∠7 and m∠5 are vertically opposite angles and are therefore equal. Thus;
m∠5 = m∠7
m∠5 = 157°
