Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes
Eduardwww [97]
For ax^2+bx+c=0 the discriminant is b^2-4ac

there are 3 basic cases of what happens for different discriminants
1. if the discriminant is less than 0, then there are no real zeroes
2. if the discriminant is 0, then it has 1 zero
3. if the discriminant is greater than 0, it has 2 zeroes


so given
0=3x^2-7x+4
a=3,b=-7,c=4
thus the discriminant is (-7)^2-4(3)(4)=49-48=1
the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0

the answer is the equation has two zeroes because the discriminant is greater than 0

This Question: 1 pt
horrorfan [7]

Answer: the length of the field is 70 yards. The width of the field is 35 yards

Step-by-step explanation:

Let L represent the length of the rectangular athletic field.

Let W represent the width of the rectangular athletic field.

A rectangular athletic field is twice as long as it is wide. This means that

L = 2W

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If the perimeter of the athletic field is 210 yards, it means that

210 = 2(L + W)

L + W = 210/2 = 105

Substituting L = 2W into L + W = 105, it becomes

2W + W = 105

3W = 105

W = 105/3 = 35

L = 2W = 2 × 35

L = 70

Julian jogs 222 kilometers east, 444 kilometers north, and then 777 kilometers west. how far is julian from his starting positio
lawyer [7]
If you would like to know how far is Julian from his starting position, you can calculate this using the following steps:

First, you have to make a right triangle, where the hypotenuse of this triangle will actually be the distance we are looking for. The distances of the other two sides are 444 kilometers, and 777 kilometers - 222 kilometers; to be exact: 444 kilometers and 555 kilometers.

The distance we are interested in ... d:
d^2 = 444^2 + 555^2
d^2 = 197136 + 308025 = 505161
d = sqrt(505161)
d = <span>710.7 kilometers
</span>
The correct result would be <span>710.7 kilometers.</span>

Which of them are functions and not functions?
elena-s [515]
Number 15 is the only function on the page because a function is when even input has a different output. so 2 numbers can’t be equal to the same output. 14 is the only one that fits that description. 13 implies that’s it’s not a function bc there are only 3 outputs (1,2, or 3) and there are 4 inputs meaning that every input will not have a different output making it not a function

2/3 divided by 9/10 simplified step-by-step
Ksivusya [100]

Answer:

20/27

Step-by-step explanation:

2/3 is the dividend,

9/10 is the divisor,

20/27 is the quotient.

Remember: 2/3 divided by 9/10

2/3 ÷ 9/10 = 2/3 x 10/9. Hence, instead of performing the division, multiplying 2/3 with the reciprocal of 9/10 is the easiest method to find what is 2/3 divided by 9/10 in fraction form.
