Answer: 4,862 students will attend the college in the next four years

Step-by-step explanation: If the college starts out with 4,000 students you need to find 5% of 4,000. To do this you would multiply 4,000 by 0.05, you should get 200. So 5% of 4,000 is 200 so the next year there will be 200 more students then last year meaning the next year will have 4,200 student. So now you'll repeat the same step multiply the number of students (now 4,200) by 0.05, then add the answer to the number of students from the previous year. So year two is:

4,200x0.05=210

4,200+210=4,410

repeat these steps till you have four years worth.

Answer:

So the first step is asking you to write the explanation on your own paper (Easy! :)

The whole equation is designed for you to get the variable "x" by itself so that you know what number it is equal to. In order to do this you need to follow the steps.

So for the second step you need to add 1 to both sides. This step is so that you can get rid of the 1 on the left side, to do this you need to add 1 because this will cancel out on the left side since you are substracting it. BUT if you add one on the left side, you also need to add it to the right side!!! (Whatever you do on one side of the equal sign you need to do on the other side)! So add one on both sides this will get rid of the 1 on the left and turn the 6 to a 7 on the right side.

NEXT STEP (Multiply both sides by -2) So (-1/2) is the same as saying 1 divided by -2 which is -0.5 as a decimal. If you want to cancel out a fraction you want to multiply it by the denominator (aka bottom number), in this case that number is -2. So if you multiply (-1/2) by -2 this cancels that fraction out on the left side and it disappears, BUT you must do it on the right side too! So you multiply 7 by -2 which is equal to -14.

Now you're left with 5x = -6! Your final step is to get rid on the 5 on the left side. To do this you simply divide it by 5 so that it cancels out on the left side and you're left with x. BUT you still divide on the right side, so x is equal to (-6/5).

I hope this helps!

It is all about getting x by itself.

explanation: congruent angles are about 48° they could be much more higher but in this case they aren't. And as you could see congruent angles aren't like that.

The rule is If two angles have the same measure then they are congruent.

Congruent angles are marked with the same number of "arcs".

Note: This picture isn't mine, it's an example of what a congruent angle could look like.

Step-by-step explanation:

To find the midpoint, add the two x-terms and divide by 2. That's the x coordinate of the midpoint.  Do the same for the two y terms; that's the y coordinate of the midpoint.  In this case, add -4 + 0 and divide by 2 to get -2, the add 7 and 3 to get 10 and divide by 2 to get 5.

[tex]\boxed {\boxed {\sf ( - \frac{9}{2}, -1) \ or \ (-4.5, -1) }}[/tex]

Step-by-step explanation:

We are asked to find the midpoint of a line segment. When you find the midpoint, you essentially find the average of the x-coordinates and the y-coordinates. The midpoint formula is:

[tex](\frac {x_2+x_1)}{2}, \frac{y_2+y_1}{2})[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the line segment. we are given the endpoints R (-6, 1) and S (-3, -3). If we match the value and the corresponding variable we see that:

Substitute the values into the formula.

[tex]( \frac{-3 + -6}{2} , \frac{ 1+ -3}{2} )[/tex]

Solve the numerators.

[tex](\frac {-9}{2}, \frac {-2}{2})[/tex]

Divide.

[tex]( - \frac {9}{2}, -1})[/tex]

The fraction can also be written as a decimal.

[tex](-4.5 , -1)[/tex]

The midpoint of the line segment RS is (-9/2, -1) or (-4.5, -1).

What is the probability of drawing a red card or a queen from a standard deck of 52 cards?

7 over 13

15 over 26

1 half

1 over 26

The probability for red card or queen is given as 15/26. The correct option is (B).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total number of red cards in the deck is 26.

And, the number of queens in the deck is 4.

Now, the probability of getting red card is given as,

P(red cards) = Number of red cards ÷ Total number of cards

⇒ P(red cards) = 26/52 = 1/2.

Similarly, the probability of queen is,

P(queen) = 4/52 = 1/13

Thus, the probability of drawing a queen or red card is given as,

P(red card or queen) = P(red card) + P(queen)

⇒ P(red card or queen) = 1/2 + 1/13 = 15/26.

Hence, the probability of drawing a red card or a queen from a standard deck of 52 cards is 15/26.

Step-by-step explanation:

Answer:

f'(x) = 5x^4 + 2x + 3x^2

Step-by-step explanation:

To find the derivative of this equation we can do two things.

One method is to use the product rule, which states that when f(x) consists of two functions multiplied to each other (meaning f(x) = g(x) * h(x)), the derivative is f'(x) = g'(x)*h(x) + g(x)*h'(x). In simple language, the derivative is found by finding the derivative of x² + 1 and multiplying it with the normal function of x³ + 1, after which you add the product of the nnormal function of x² + 1 and the derivative of x³ + 1.

it might be clearer when I show you:

[tex]f(x) = (x^2 + 1)(x^3 + 1)\\f'(x) = (2x)(x^3 + 1) + (x^2 + 1)(3x^2)\\Simplify:\\f'(x) = 2x^4 + 2x + 3x^4 + 3x^2 = 5x^4 + 3x^2 + 2x\\[/tex]

If you are not familiar with this rule you can first write out the function and then use the basic rule:

[tex]f(x) = (x^2 +1)(x^3+1) = x^5 + x^2 + x^3 + 1\\f'(x) = 5x^4 + 2x + 3x^2[/tex]

Answer:

3 nickels and 5 quarters

Step-by-step explanation:

Let n = number of nickels

q = number of quarters

q = n+2

.25q + .05n = 1.40

Using the first equation and replacing q in the second equation

.25( n+2) + .05n = 1.40

Distribute

.25n+.50 +.05n = 1.40

Combine like terms

.30n +.5 = 1.40

Subtract .5 from each side

.3n +.5-.5 = 1.40-.4

.3n = .9

Divide by .3

.3n/.3 = .9/.3

n = 3

q = n+2

q=5

Step-by-step explanation:

Let the

Nickel coin = x

Quarter coin = y

y = n + 2

0.25y + 0.05x = 1.4

0.25(x + 2) + 0.05x = 1.4

0.25x + 0.5 + 0.05x = 1.4

0.25x + 0.05x = 1.4 - 0.5

0.30x = 0.9

x = 0.9/0.3

x = 3

y = 3 + 2 = 5
