Answers
Answer:
[tex]\frac{1}{7w^{2} }[/tex]
Step-by-step explanation:
The expression can be simplified only if you take the same quantity out of both the top and bottom.
You can simplify the numbers by taking a factor of 3 out of the expression.
The numerator changes to 1 (because 3 / 3 = 1) and the denominator changes to 7 (because 21 / 3 = 7).
The variables can be eliminated through subtraction. The numerator variable is completely removed because you can subtract w³ from w⁵. This makes the denominator w² (because w⁵ - w³ = w²).
which of the following expresses the possible number of positive real solutions for the polynomial equation shown below
Answers
The polynomial equation x³ - 4x² - 7x + 28 = 0, has solutions -√7, √7, and 4, among which √7 and 4 are positive real solutions. Hence we have two positive real solutions. Hence, option D is the right choice.
In the question, we are asked for the number of positive real solutions for the polynomial equation, x³ - 4x² - 7x + 28 = 0.
To find the solutions, we do as follows:
x³ - 4x² - 7x + 28 = 0,
or, (x³ - 7x) - (4x² + 28) = 0 {Grouping},
or, x(x² - 7) - 4(x² - 7) = 0 {Taking common},
or, (x - 4)(x² - 7) = 0 {Grouping},
or, (x - 4)(x + √7)(x - √7) = 0 {Using the formula: [tex]a^2 - b^2 = (a+b)(a-b)[/tex]}.
By the zero-product rule, the solutions are:
x - 4 = 0, or, x = 4,
x + √7 = 0, or, x = -√7,
x - √7 = 0, or, x = √7.
Thus, the positive real solutions are 4, and √7. Hence, there are two positive real solutions.
Thus, the polynomial equation x³ - 4x² - 7x + 28 = 0, has solutions -√7, √7, and 4, among which √7 and 4 are positive real solutions. Hence we have two positive real solutions. Hence, option D is the right choice.

A local pizza parlor has the following list of toppings available for selection. The parlor is running a special to encourage patrons to try new combinations of toppings. They list all possible three-topping pizzas (3 distinct toppings) on individual cards and give away a free pizza every hour to a lucky winner. Find the probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni.
Answers
The probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni is 1/560 given that there are 16 toppings to choose from. This can be obtained by finding the total number of all possible three-topping pizzas (3 distinct toppings) using combination formula and finding the probability.
What is the required probability?Given that there are 16 toppings,
the total number of all possible three-topping pizzas,
ⁿCₓ = [tex]\frac{n!}{x!(n-x)!}[/tex] = 16!/[3!(16-3)!] = 16!/[3!(13)!] = 14×15×16/3×2 =560
Probability of choosing pizza topped with ham, artichoke hearts, and pepperoni,
P(ham, artichoke hearts, pepperoni) = 1/560
Hence the probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni is 1/560 given that there are 16 toppings to choose from.

y < 2x + 3
y > −2x + 3
y < −2x + 3
Answers
The linear inequality of the given graph is: D. y < -2x + 3.
How to Determine the Linear Inequality of a Graph?First, using two points on the line, (0, 3) and (1.5, 0), find the slope (m).
Slope (m) = change in y / change in x = (3 - 0) / (0 - 1.5)
Slope (m) = 3/-1.5 = -2.
Next, substitute (x, y) = (0, 3) and m = -2 into y = mx + b to find the value of b.
3 = -2(0) + b
3 = 0 + b
b = 3
Substitute m = -2 and b = 3 into y < mx + b (the shaded part is at the left, so we use the "<" sign)

The expected cost to Palmetto Insurance Company for each year Miranda has the policy is illustrated.
How to illustrate the information?Term policy amount = $50000
x (age) 50 51 52 53 54
p (death) 0.0032 0.0035 0.0038 0.0041 0.0044
1. Expected cost to Palmetto Insurance Company for each year Miranda has the policy
= P(death for a given year)*term policy amount
Thus, when x = 50
Expected cost = P(x) * 50000 = 0.0032*50000 = $160
Thus, when x = 50
Expected cost = P(x) * 50000 = 0.0032*50000 = $160
Thus, when x = 51
Expected cost = P(x) * 50000 = 0.0035*50000 = $175
Thus, when x = 52
Expected cost = P(x) * 50000 = 0.0038*50000 = $190
Thus, when x = 53
Expected cost = P(x) * 50000 = 0.0041*50000 = $205
Thus, when x = 54
Expected cost = P(x) * 50000 = 0.0044*50000 = $220
Thus, the table will become
x (age) 50 51 52 53 54
p (death) 0.0032 0.0035 0.0038 0.0041 0.0044
Expected cost 160 175 190 205 220
2) For company to make $500 profit
They should charge $500 more than their expected cost
= $(500 + 160 + 175 + 190 + 205 + 220)
= $1450
Thus, they need to charge $1450 overall or (1450/5 = $290 per year)

a) m< TRV = 60° (given)
m<TRS = 4x° (given)
Thus, it can be concluded from the diagram that:
<TRV ≅ m<BRW (vertically opposite angle property)
Also,
m<TRS ≅ m<VRW (vertically opposite angle property)
But,
m<VRW = m<VRZ + m<ZRW
Thus,
m<TRV ≅ m<BRW = 60°
m<TRV + m<BRW + m<TRS + m<VRW = [tex]360^{o}[/tex]
60° + 60° + m<TRS + m<VRW = [tex]360^{o}[/tex]
m<TRS + m<VRW = [tex]360^{o}[/tex] - [tex]120^{o}[/tex]

2m<TRS = [tex]240^{o}[/tex] (since m<TRB = m<VRW )

The length of the radius of the circle is 4.9cm.
What is circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.
The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.
Calculation for the length of the radius of the circle-
In order to overcome this issue, we must first translate the angle from radians to degrees.
The central angle of circle is 7/6π rads = 210 degrees.
Length of the arc is 18 cm.

Taking as the most likely 3 (because a 39 year old is more likely than a 9 year old, 69 year old, or 99 year old to have a child who doesn’t already know their father’s age) we’ll try 39, 40. 3+9=12, 4+0=4, 12/3=4, this is a possible solution.

c. 15 hours
d. 2½ hours
Answers
Answer:
b, 20 hours
Step-by-step explanation:
First, find out how many times 66 (what Vinny made) goes into 165. (what Vinny wants to make) the answer is 2.5. Then, multiply 8 by 2.5 as well. You get 20. The answer is b, 20.
