Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes the discriminant and the number of zeros? The equation has one zero because the discriminant is 1. The equation has one zero because the discriminant is a perfect square. The equation has two zeros because the discriminant is greater than 0. The equation has no zeros because the discriminant is not a perfect square.

Answers

The correct option is: The equation has two zeros because the discriminant is greater than 0.

Explanation:

First, remember the following conditions:
1. If the discriminant is less than zero, there will be no zeros.
2. If the discriminant is equal to zero, there will be one zero.
3. If the discriminant is greater than zero, there will be two zeros.

For the general equation of the form 
ax^2 + bx + c = 0, the discriminant is b^2 - 4ac.

Let's find the discriminant and then compare it with the conditions mentioned above.

Given Equation:
3x^2 -7x + 4 =0

a = 3, b = -7, c = 4

Now find the discriminant:

b^2 - 4ac
(-7)^2 - 4(3)(4)
Discriminant = 1

As the discriminant is greater than 0 (which in this case is 1), the equation has two zeros (as mentioned in the above conditions).

2. The line BC in the figure above is the ___ of the cylinder.A. slant height
B. axis
C. altitude
D. vertex

Answers

Answer:

BC denotes the axis of the cylinder in the given figure.

Step-by-step explanation:

Given an oblique cylinder. It is three dimensional shape having sides not perpendicular to the base. it means it is leaning toward one side left or right as shown in figure below.

We have to determine what BC denotes.

Height is always perpendicular to the base so the given line BC is the axis of the cylinder . When there is a slant to the cylinder axis is also not perpendicular to the base.

Thus, BC denotes the axis of the cylinder in the given figure.

The line BC in the figure above is the AXIS of the cylinder.

Axis of the cylinder is the line formed by the centers of the bases of a cylinder.

Please help! Correct answer only!For a fundraiser, there is a raffle with 100 tickets. One ticket will win a $150 prize, and the rest will win nothing. If you have a ticket, what is the expected payoff?


$ ___

Answers

Answer:

Expected Payoff ⇒ $ 1.50 ; Type in 1.50

Step-by-step explanation:

Considering that 1 out of the 100 tickets will have a probability of winning a 150 dollar prize, take a proportionality into account;

100 - Number of Tickets,\n1 - Number of Tickets You Can Enter,\n\n1 / 100 - Probability of Winning,\n$ 150 - Money Won,\n\nProportionality - 1 / 100 = x / 150, where x -

Thus, Solution ; Expected Payoff ⇒ $ 1.50

If lines ab and cd are parallel, which of the following statements are true? Check all that apply.

A. Ab and cd are skew lines
B. Ab and cd are perpendicular
C. Ab and cd intersect at a single point
D. Ab ll cd
E. Ab is perpendicular to cd
F. Ab and cd are coplanar

Answers

The correct answers are:
(D) ab ll cd 
(F) a
b and cd are coplanar

Explanation:
The symbol for parallel is " 
ll ". Therefore, if we translate the given sentence, ab and cd are parallel, into the Mathematical terms, we can write it as:

ab ll cd (Option D)

Where ab = line
cd = line

Furthermore, the lines ab and cd are coplanar because they form the plane. In other words, you can say that the lines ab and cd lie on the same plane. (Option F)

Hence the correct answers are:
(D) ab ll cd 
(F) ab and cd are coplanar
If lines ab and cd are parallel, the following statements that are true are letters D, F. 
D. Ab ll cd 
F. Ab and cd are coplanar

Explain how to do 63 is 90% of what number

Answers

To do this, you must first turn 90 percent into a decimal, by dividing it by 100.  The decimal should be .90 .  

Now, you must divide 63 by .90 which will give you the number that 63 is 90% of.  The answer should be 70.

To help you understand this, think about finding 90% of 70.  To do this you could do 70 times .90 (decimal form of 90%) which would give you 63 as your answer.  This is because 70 is being multiplied not by 1 (its fullself), but by .90 which will give you 90% of 70.

Finally, the opposite of multiplying is dividing so to find 90% of 63 you do the opposite.  You divide instead of multiply since you are trying to find what 63 is 90% of.

Remember to study and work on finding the lesser number that represents the percentages of the full numbers and turning them into values, and vice versa, like in this question.  So for example, finding what number is 10% of 90.  You would have to multiply 90 by .10  .  The answer would be 9.

To recap, the answer you should come up with for your question is 70.

I hope this helps!
