Will the standard form of 8.5 × 10–3 be more or less than 1? Explain what effect the negative exponent has.
Answers
The value is less than 1 and the impact of the negative exponent is that it moves the decimal point to the left
What is standard form?Standard form can be defined as a mathematical way of writing large or too small numbers in a defined manner.
Given the standard form;
8.5 × 10–3
The negative exponent (-3) indicates an addition of three zeros ruled out from the start.
It could be written as;
0. 0085
This is 0. 9915 less than the value of 1
The impact of the negative value is that it moves the decimal point to the left.
Thus, the value is less than 1 and the impact of the negative exponent is that it moves the decimal point to the left

To manufacture scooters, the manufacturer has a fixed cost of 34,400$$ plus a variable cost of n $$ per scooter. Find 100$$, the number of scooters that need to be produced so that the average cost per scooter is 180$$.
Answers
Answer:
The number of scooters that need to be produced so that the average cost per scooter is $180 is 430 scooters.
Step-by-step explanation:
Note: This question is not properly structured/written. The question is therefore rewritten properly before answering the question as follows:
To manufacture scooters, the manufacturer has a fixed cost of $34,400 plus a variable cost of $100 per scooter. Find n, the number of scooters, that need to be produced so that the average cost per scooter is $180.
The explanation of the answer is now provided as follows:
The number of scooters can be calculated as follows:
Variable cost per scooter = $100
n = number of scooter = ?
Total variable cost = Variable cost per scooter * n = $100 * n = $100n
Total cost = Fixed cost + Total variable cost = $34,400 + $100n
Average cost per scooter = Total cost / n = $180 ................ (1)
Substituting the value for Total cost into equation (1) and solve for n, we have:
($34,400 + $100n) / n = $180
$34,400 + $100n = $180n
$34,400 = $180n - $100n
$34,400 = $80n
n = $34,400 / $80
n = 430
Therefore, the number of scooters that need to be produced so that the average cost per scooter is $180 is 430 scooters.

The endpoints of CD are (-2,-4) and D (6,2). What are the coordinates of the midpoint of CD?
Answers
The midpoint of the line segment CD whose coordinates (-2,-4) and D (6,2) will be (2, -1).
What is the mid-point of the line segment?Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).
Then the coordinate of the mid-point of the line segment is given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
The endpoint of the segment CD is given as C(-2, -4) and D(6, 2). Then the mid-point of the line segment CD will be
(x, y) = [(-2 + 6) / 2, (-4 + 2) / 2]
(x, y) = (4/2, -2/2)
(x, y) = (2, -1)
The midpoint of the line segment CD whose coordinates (-2,-4) and D (6,2) will be (2, -1).

[tex](f . g)(x) =4(5^x)[/tex] ---- (3)
[tex](f / g)(x) = \frac{4}{5^x}[/tex] ----- (4)

[tex]F(t) = \frac{9}{5}t^2 + 32[/tex] ---- (9)
[tex]T(t) = (t - 2)^2 - 4[/tex] --- (10)
Step-by-step explanation:
Given
[tex]f(x) = 3[/tex]
[tex]g(x) = 4 - 6x[/tex]
Solving (1): (f + g)(x)
[tex](f + g)(x) = f(x) + g(x)[/tex]
So, we have:
[tex](f + g)(x) = 3 + 4 - 6x[/tex]
[tex](f + g)(x) = 7 - 6x[/tex]
Solving (2): (f - g)(x)
[tex](f - g)(x) =f(x) - g(x)[/tex]
So, we have:
[tex](f - g)(x) =3 - (4 - 6x)[/tex]
[tex](f - g)(x) =3 - 4 + 6x[/tex]
[tex](f - g)(x) =-1 + 6x[/tex]
[tex](f - g)(x) = 6x - 1[/tex]
Given
[tex]f(x) = 4[/tex]
[tex]g(x) = 5^x[/tex]
Solving (3): (f . g)(x)
[tex](f . g)(x) =f(x) * g(x)[/tex]
So, we have:
[tex](f . g)(x) =4 * 5^x[/tex]
[tex](f . g)(x) =4(5^x)[/tex]
Solving (4): (f / g)(x)
[tex](f / g)(x) = \frac{f(x)}{g(x)}[/tex]
So, we have:
[tex](f / g)(x) = \frac{4}{5^x}[/tex]
Given
f(x) = x + 1
g(x) = -8 - 8x
Solving (5): (f + g)(x)
[tex](f + g)(x) = f(x) + g(x)[/tex]
So, we have:
[tex](f + g)(x) = x + 1 -8-8x[/tex]
Collect Like Terms
[tex](f + g)(x) = x -8x+ 1 -8[/tex]
[tex](f + g)(x) = -7x-7[/tex]
Solving (6): (f - g)(x)
[tex](f - g)(x) = f(x) - g(x)[/tex]
So, we have:
[tex](f - g)(x) = x + 1 -( -8-8x)[/tex]
[tex](f - g)(x) = x + 1 +8+8x[/tex]
Collect Like Terms
[tex](f - g)(x) = x +8x+ 1 +8[/tex]
[tex](f - g)(x) = 9x+ 9[/tex]
Solving (7): (f . g)(x)
[tex](f . g)(x) = f(x) . g(x)[/tex]
So, we have:
[tex](f . g)(x) = (x+1) . (-8 - 8x)[/tex]
Factorize
[tex](f . g)(x) = (x+1) .(-8) (1 + x)[/tex]
Rewrite as:
[tex](f . g)(x) = (x+1) .(-8) (x+1)[/tex]
[tex](f . g)(x) = (-8)(x+1) (x+1)[/tex]
[tex](f . g)(x) = (-8)(x+1)^2[/tex]
Solving (8): (f / g)(x)
[tex](f / g)(x) = \frac{f(x)}{g(x)}[/tex]
So, we have:
[tex](f / g)(x) = \frac{(x+1)}{(-8-8x)}[/tex]
Factorize
[tex](f / g)(x) = \frac{(x+1)}{-8(1+x)}[/tex]
[tex](f / g)(x) = \frac{1}{-8}[/tex]
[tex](f / g)(x) = -\frac{1}{8}[/tex]
Solving (9):
From the question, we have that:
[tex]F(c) = \frac{9}{5}c + 32[/tex]
[tex]C(t) = t^2[/tex]
Required
Determine function F in terms of c
The implication of this question is to solve for [tex]F(c(t))[/tex]
If [tex]F(c) = \frac{9}{5}c + 32[/tex] and [tex]C(t) = t^2[/tex],
Then
[tex]F(c(t)) = \frac{9}{5}*t^2 + 32[/tex]
[tex]F(c(t)) = \frac{9}{5}t^2 + 32[/tex]
This can be rewritten as:
[tex]F(t) = \frac{9}{5}t^2 + 32[/tex]
Solving (10):
[tex]T(h) = h^2 - 4[/tex]
[tex]h(t) = t - 2[/tex]
Required
Find [tex]T(h(t))[/tex]
If [tex]T(h) = h^2 - 4[/tex] and [tex]h(t) = t - 2[/tex], then
[tex]T(h(t)) = (t - 2)^2 - 4[/tex]
This is gotten by substituting t -2 for h
The solution can be rewritten as:
[tex]T(t) = (t - 2)^2 - 4[/tex]
