Answer:

Step-by-step explanation:

The greater the magnitude of the leading coefficient, the narrower the parabola.

Widest: f(x) = 0.5x²

Next: f(x) = -x²

Next: f(x) = 2x²

Narrowest: 3x²

(largest to smallest)

1. f(x)= 0.5x^2

2. f(x)= -x^2

3. f(x)= -2x^2

4. f(x)= 3x^2

hope this helps, loves!! :)

What if it is that cool pirate money that is shaped weird? I hear it is 11/12 foot long and ¾ wide. What is the square foot of t
cestrela7 [59]

If you are asking how to find the square feet of the "weirdly shaped pirate money" you'd need to multiply the length and width. So:

11/12 * 3/4 = 33/48

So the answer is 33/48 square feet

If you are not asking for this answer word your question better please.

Answer: Angle DCE would be 12

Step-by-step explanation:

Assuming that angle BCD is right then just set up equation to equal to 90

4x+10+2x+8=90

then solve

6x+18+90

6x=72

x=12

A coin is tossed, and a standard number cube is rolled. What is the probability that the coin shows heads and the number cube sh
Genrish500 [490]
The correct answer to this question is this one: "C. One-Fourth."

The total possibility that the head and even no on dice appears is 3.

The total possible choices are 12 {head ->(1,2,3,4,5,6) & tail->(1,2,3,4,5,6)}. so the probability is 3/12= 1/4.


These are independent events so the total probability will be the product of the individual probabilities:

Perform the following operations and write the answers in radical form.
strojnjashka [21]

Given:

Part A: \sqrt{7}+\sqrt{3}+\sqrt{98}-\sqrt{18}

Part B: 3 \sqrt{5}-3 \sqrt{11}+2 \sqrt{121}-3 \sqrt{90}

To find:

The simplified radical form.

Solution:

Part A: \sqrt{7}+\sqrt{3}+\sqrt{98}-\sqrt{18}

\sqrt{98}=\sqrt{7^2 \times 2} =7 \sqrt{2}

\sqrt{18}=\sqrt{3^2 \times 2} =3 \sqrt{2}

Substitute these in the given expression.

\sqrt{7}+\sqrt{3}+\sqrt{98}-\sqrt{18}=\sqrt{7}+\sqrt{3}+7\sqrt{ 2}-3\sqrt{ 2}

Add or subtract the coefficient of same radical.

                                    =\sqrt{7}+\sqrt{3}+(7-3)\sqrt{ 2}

                                    =\sqrt{7}+\sqrt{3}+4\sqrt{ 2}

Part B: 3 \sqrt{5}-3 \sqrt{11}+2 \sqrt{121}-3 \sqrt{90}

2 \sqrt{121}=2\sqrt{11^2}

           =2\times 11

           = 22

3 \sqrt{90}=3\sqrt{3^2 \times 10}

           =3\times 3 \sqrt{10}

           =9 \sqrt{10}

Substitute these in the given expression.

3 \sqrt{5}-3 \sqrt{11}+2 \sqrt{121}-3 \sqrt{90}=3 \sqrt{5}-3 \sqrt{11}+22-9 \sqrt{10}
