Answer:

Step-by-step explanation:

I think the first part of that is asking for the equation for the line of symmetry, although I do not have access to your drop down menu to know for sure!  The axis of symmetry is the equation that splits the parabola into 2 parts that are mirror images of each other.  In this type of parabola, it will be an "x = " equation.  The line that splits the parabola in half is the line x = -2.  The function is increasing where the y values are going up.  This happens in the interval  (-∞, -2].

The function is decreasing where the y values are going down.  This happens in the interval [-2, ∞)

Can someone help me with this?​

Answer:

1. AE= 312

2. AC = 161

Step-by-step explanation:

Hey there!

In order to solve the first question, we need to think of possible "C" values

Then after finding the "C" value, we can then find the "A" and "E" values

So:

AC = 24 and CE = 13

What factors do 24 and 13 have in common?

Well, only 1 since 13 is a prime number]

So this means that C has to be 1

Now we know that A is 24 and E is 13

Now we have to multiply them together

24 x 13 is 312

So AE= 312

Now we go on to the second question

We can use the same strategy we used for number one

Instead of finding what C is, we need to find out what E is, since there is E in both of the statements

So:

CE = 7 and AE = 23

What common factors do these two numbers have?

Again, only 1, meaning that E can only be 1

Now we know that C is 7 and A is 23

Since we know this, we can multiply these two numbers together and get our final answer: 161

So AC = 161

A solenoid has a magnetic field of magnitude 0.50T when carrying a current of 400 A. The solenoid is 8.0 m long. What is the num
mixer [17]

Answer:

The correct answer is "995.22 turns".

Step-by-step explanation:

The given values are:

Magnetic field,

B = 0.50 T

Current,

i = 400 A

Length of solenoid,

L = 8.0 m

As we know,

⇒ B=\mu_0ni

then,

⇒ n=\frac{B}{\mu_0i}

On substituting the given values, we get

⇒    =\frac{0.50}{4 \pi\times 10^{-7}\times 400}

⇒    =\frac{0.50}{5.024\times 10^{-4}}

⇒    =995.22 \ turns
