a = 1/2bh, solve for b

If j(x) = 4^(x - 2), the solving the given expression [j(x + h) - j(x)]/h gives;

[j(x + h) - j(x)]/h = (4^(x - 2))(4^(h) - 1)]/h

We are given the function as;

j(x) = 4^(x - 2)

Now, we want to solve the expression;

[j(x + h) - j(x)]/h

This gives us;

j(x + h) = 4^(x - 2 + h)

Thus, our expression is now;

[j(x + h) - j(x)]/h = [4^(x - 2 + h) - 4^(x - 2)]/h

Now, according to laws of exponents, we know that;

y³ × y² = y³ ⁺ ²

Thus;

4^(x - 2 + h) = 4^(x - 2) × 4^h

Therefore;

[4^(x - 2 + h) - 4^(x - 2)]/h = (4^(x - 2))(4^(h) - 1)]/h

The solution to the equation g(x) = 6x - 9 whenx = -8b is g(-8b) = -48b - 9

From the question, the equation of the function is given as

g(x) = 6x - 9

Also, we have the value of the variable to be

x = -8b

So, we substitute -8b for x in the equation of the function

g(x) = 6x - 9

The above equation becomes

g(-8b) = 6(-8b) - 9

Open the brackets in the above expression

g(-8b) = -48b - 9

The above equation cannot be firther simplified

Hence, the solution is g(-8b) = -48b - 9

The velocity of the body under simple harmonic motion is equal to - 5√3 / 2. (Correct choice: B)

Simple harmonic motion is a kind of self-sustained periodic motion that observed the following formula:

y = y' + Δy · cos ωt     (1)

Where:

The equation for the velocity of the body in simple harmonic motion is found differentiating (1):

v = - ω · Δy · sin ωt      (2)

If we know that ω = 1, t = 2π / 3 and Δt = 5, then the velocity of the body is:

v = - 1 · 5 · sin (2π / 3)

v = - 5 · sin (2π / 3)

v = - 5 · √3 / 2

v = - 5√3 / 2

Probability is expressed as

number of favorable outcomes/number of total outcomes

In a standard deck of cards, the total number of cards is 52.

There are 13 spades in a standard deck. Thus,

probability of selecting a spade = 13/52 = 1/4

There are 26 red cards in a standard deck of cards. Since the first card was replaced, the total number of cards remains 52.

probability of selecting a red card = 26/52 = 1/2

There are 4 queens in a standard deck of cards. Since the second card was also replaced, total number of cards is still 52. Thus,

Probability of selecting a queen = 4/52 = 1/13

Thus, the probability that the first card will be a spade, the second card will be a red card, and the third card will be a queen is

1/4 x 1/2 x 1/13

The expression used to depict area will be 9 / (3x - 1).

A rectangle may be defined as a closed figure with four sides and four interior angles. The interior angles are 90°.

The given expression for area = 27x - 9

Factorize 27x - 9

Taking 9 as greatest common factor outside, we get

27x - 9 = 9(3x - 1)

We know that the area of rectangle with dimensions length by breadth is given by:-

Area = Length x Breadth

It is a trigonometric function, hence there is no rule to find the minimum value of the function as there is for a quadratic function, for example.

Since there is no rule, we have to sketch the graph of the function in the given domain of 0 < x < 6.

Using a graphing calculator, the graph of the function is given at the end of the answer, with minimum point at (5.647, -1.76), hence the correct option is:

Walter's daily wage = $ 50

Tips = 15% of the total cost of the dinner he serves

Tuesday earnings = $ 170

Therefore,

Tips = 170 - 50

Tips = 120

For finding the cost of the dinners, we use Direct Rule of Three, as follows:

Percentage Cost

15 120

100 x

_____________________

120 * 100 = 15 * x

12,000 = 15x

Dividing by 15 at both sides:

15x/15 = 12,000/15

x = 800

The total cost of the dinners Walter serverd on Tuesday was $ 800

The width of the smaller rectangle is 4 inches.

A rectangle has four sides, but because the sides are paired, it only has two distinct dimensions. The width is traditionally the shortest of these two dimensions, but when the rectangle is shown lying on its side, the horizontal side is commonly referred to as the width.

Given:

The dimensions of the smaller rectangle are:

Length = 8 inches

Width = x inches

The dimensions of the larger rectangle are:

Length = 10 inches

Width = 5 inches

Using proportion we determine the value of x,

[tex]\frac{8}{x} = \frac{10}{5}[/tex]

Cross-multiply the terms,

8 × 5 = 10x

x = 40/10 = 4

Therefore, the width of the smaller rectangle is 4 inches.
