Use the information given to write the equation for the quadratic function.
a. The x-intercepts are (-4, 0) and (3,0), and the parabola opens down.
b. The vertex is (-8, -2), and the parabola opens up.

Answers

Answer 1

Answer:

y = -x² - x/22 + 6/11

Step-by-step explanation:

Standard form, is y = ax² + bx + c

We need to use standard form (though we could use vertex form, but it is easier to do standard form)

Substitute the x and y values that they give into y = ax² + bx + c

Because the parabola passes through...

(-4, 0), then 0 = (-4)²a + (-4)b + c

(3, 0), then 0 = 9a + 3b + c

(-8, -2), then -2 = 64a - 8b + c

So, we get this system:

16a − 4b + c = 0

9a + 3b + c = 0

64a − 8b + c = −2

Because you are learning about parabolas, I am assuming that you can solve a system, but the answers are:

a = -x²/22

b = -x/22

c = 6/11

So, the equation of the parabola is:

y = -x²/22 - x/22 + 6/11

I hope this helps! Feel free to ask any questions!

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

[tex]\rm \rightarrow \dfrac{(27)^{b/3}}{(9)^{a/2}}[/tex]

Simplify the expression, then we have

⇒ (∛27)ᵇ / (√9)ᵃ

⇒ 3ᵇ / 3ᵃ

⇒ 1/3ᵃ⁻ᵇ

⇒ 1/3²

⇒ 1/9

The value of the given expression will be 1/9.

The mass of Parcel A was 0.7 kg. Parcel B was heavier than Parcel A.
Parcel C had the same mass as Parcel B. The total mass of the three
parcels was 2.5 kg. What was the mass of Parcel C?​

Answers

Answer: 0.9kg

Step-by-step explanation:

Since we are informed that Parcel C had the same mass as Parcel B, let their mass be represented by x.

Therefore,

Parcel A + Parcel B + Parcel C = 2.5

0.7 + x + x = 2.5

0.7 + 2x = 2.5

2x = 2.5 - 0.7

2x = 1.8

x = 1.8/2

x = 0.9

The mass of parcel C is 0.9kg

you have to know that the sum of angles of any quadrilateral shape is equal to 360 after finding the value of X we substituted it in the unknown angles .

A triangle has sides with lengths of 5 centimeters, 12 centimeters, and 15 centimeters. Is it a right triangle

Answers

Answer:

No

Step-by-step explanation:

You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.

This is not true since 144+25 is 169, not 196

Answer:

No, it is not a right triangle.

Step-by-step explanation:

You can determine whether a triangle is a right triangle by using the pythagorean theorem.

a^2 + b^2 = c^2

c will always be the longest side of the triangle, so in this case you need to substitute 5 and 12 in for a and b and see if it simplifies to 15.

5^2 + 12^2 = c^2

25 + 144 = c^2

c^2 = 169

c = 13

C would be 13, not 15, so the triangle is not a right triangle
