Answer:

Below

Step-by-step explanation:

-2x^2 + 11 is a quadratic equation since the degree is 2.

It's not a linear one since it does not give a straight line after graphing it

Answer: A

Step-by-step explanation:

For this problem, let's think about the properties of the listed expressions.

We can eliminate B. We know that a linear line is a straight line. It doesn't curve at all. A linear line should not have a power such as the one in the problem. The only power it should have is to the power of 1. Therefore, we can eliminate B.

We can eliminate C. A cubic expression has a cubed in it, meaning it is to the power of 3. The given problem is in power 2. Therefore, we can eliminate C.

We can eliminate D. Though you may think this is an exponential expression because the given expression has an exponent, this is not the case. An expoenetial function actually has x as the exponent, not a number. Therefore, we can eliminate D.

Since we have eliminated D, A is the correct answer.

Answer:

1/60 probabiliity

Step-by-step explanation:

You have two independent events that you want to put together.

Let Pr. mean "probability"

Pr(5 from 10 cards and 2 on a dice ) = Pr(5 from 10 cards) * Pr( 2 on a dice)

Pr(5 from 10 cards and 2 on a dice ) =(1/10) * (1/6)

= 1/60

Pr(5 from 10 cards and 2 on a dice ) =0.0167

or 1.67% probability

Hey there! I'm happy to help!

Let's look at our diameters.

1*10^2^1\\5*10^2^2

We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.

\frac{5*10^2^2}{1*10^2^1} \\

We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x

\frac{5*10^2^2}{1*10^2^1} = 5*10=50

Therefore, your answer is 50.

Have a wonderful day! :D
