Answer:

  4)  6x

  5)  2x +3

Step-by-step explanation:

We can work both these problems at once by finding an applicable rule.

  [tex]\text{For $f(x)=ax^n$}\\\\\lim\limits_{h\to 0}\dfrac{f(x+h)-f(x)}{h}=\lim\limits_{h\to 0}\dfrac{a(x+h)^n-ax^n}{h}\\\\=\lim\limits_{h\to 0}\dfrac{ax^n+anx^{n-1}h+O(h^2)-ax^n}{h}=\boxed{anx^{n-1}}[/tex]

where O(h²) is the series of terms involving h² and higher powers. When divided by h, each term has h as a multiplier, so the series sums to zero when h approaches zero. Of course, if n < 2, there are no O(h²) terms in the expansion, so that can be ignored.

This can be referred to as the power rule.

Note that for the quadratic f(x) = ax^2 +bx +c, the limit of the sum is the sum of the limits, so this applies to the terms individually:

  lim[h→0](f(x+h)-f(x))/h = 2ax +b

__

4. The gradient of 3x^2 is 3(2)x^(2-1) = 6x.

5. The gradient of x^2 +3x +1 is 2x +3.

__

If you need to "show work" for these problems individually, use the appropriate values for 'a' and 'n' in the above derivation of the power rule.

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?

Answers

Answer:

7

Step-by-step explanation:

6,300 divide by 900 would equal 7

Answer:

7 beams

Step-by-step explanation:

To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:

6,300 ÷ 900 = 7

So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

Help me do 1/6+1/4 make sure the demonator is the same

Answers

Answer: [tex]\boxed{\boxed{\sf\frac{5}{12}=0.416666667}}[/tex]Solution Steps:

______________________________

1.) Find the LCF of 6 and 4: [tex]6,4=12[/tex]

 - We do this because in order to add these, they must have the same denominator. So you must find the LCF, (Least Common Factor) of 6 and 4.

2.) Convert the fractions to have the same denominator: [tex]\frac{1}{6}=\frac{2}{12}[/tex] [tex]\frac{1}{4}=\frac{3}{12}[/tex]

 - [tex]\frac{1}{6}[/tex] changes to [tex]\frac{2}{12}[/tex] by multiplying the numerator and denominator by 2. And  [tex]\frac{1}{4}[/tex] changes to [tex]\frac{3}{12}[/tex] because you multiply the numerator and denominator by 3.

3.) Add the numerators: [tex]2+3=5[/tex]

 - Since both fractions have the same denominator all you have to do is add the numerators together.

Brandon says that the absolute value of a number and the opposite of a number is the same thing. Is Brandon correct? Use examples to help you explain.

Answers

Answer:

No, Brandon is not correct in making that statement

Step-by-step explanation:

No, Brandon is not correct in making that statement. The absolute value of a number is the total distance between that number and 0. Brandon most likely states this because the absolute value of a negative number such as -5 would actually be the opposite, which is 5. This is not true for the absolute value of a positive such as 5, which instead is actually just 5. Meaning that the absolute value of a positive integer is the same value and NOT the opposite.

- The new apartment you ałe about to sign a one-year lease on is $1,500 per month. The lease
requires you to put up first month's rent and a $750 security deposit to move in. In addition,
keeping your cat will cost an additional $300 for a pet deposit. How much do you need to write a
check for to the landlord at the time of move in?

Answers

Answer:

Total amount = $2550

Step-by-step explanation:

To move in the apartment payments to be done,

1). First month rent = $1500

2). Security deposit = $750

3). Pet deposit = $300

Total payment to be done = 1500 + 750 + 300

                                            = $2550

Therefore, total amount to be paid = $2550

I will write a check of $2550.

How many Terminating Zeros are at the end of 631! when this number is multiplied out

Answers

Answer:

3 zeros

Step-by-step explanation:

When The factorial is the product of all integers that are less than or equal to n but that is greater than or equal to 1. so that The factorial value of 0 is by definition equal to 1. so that suppose that For negative integers, factorials are not defined. so we can do The factorial and can be seen as the result of multiplying a sequence of descending natural numbers (such as 3 × 2 × 1).

          Thus The factorial symbol is the exclamation mark !. like this

Using The factorial formula is  

        If n is a natural number greater than or equal to 1, then

             n! = n x (n - 1) x (n - 2) x (n - 3) ... 3 x 2 x 1

When If n = 0, then n! = 1, by convention it. Thus, The factorial of 631 is calculated, through its definition, can we this way: 631! = 631 • 630 • 629 • 628 ... 3 • 2 • 1

Answers

Answer:

56π

Step-by-step explanation:

1. Approach

To find the radius of a circle, use the formula;

[tex]A = r^{2}[/tex]π

To find the area of the shaded region, find the area of the larger circle, and then subtract the area of the smaller circle from it.

It is given that the larger circle has a radius of 9, and the smaller has a radius of 5.

2. Area of the larger circle

[tex]A = r^{2}[/tex]π

Substitute in known value (use 3.14 for π)

[tex]A = (9)^{2} * 3.14[/tex]

A = 254.47

3. Area of the smaller circle

[tex]A = r^{2}[/tex]π

Substitute in known value (use 3.14 for π)

[tex]A = (5)^{2} * 3.14[/tex]

A = 78.54

4. Area of the shaded region

Subtract the area of the smaller circle from the area of the larger circle;

254.47 - 78.54 = 175.93

Answer:

x=13

Step-by-step explanation:

According to the question

3x+5x-14=90

8x-14=90

8x=90+14

8x=104

x=104/8

x=13

180 = 90 + 3x + 5x - 14
180 - 90 + 14 = 3x + 5x
104 = 8x
104/8 = x
x = 13

Checking:
3(13) + 90 + 5(13) - 14 = 180
180 = 180
So x=13

Answer:

-1 < x ≤ 3

Step-by-step explanation:

First, we need to simplify this inequality.

9 > -5x + 4 ≥ -11 (Given)

5 > -5x ≥ -15 (Subtract 4 on both sides)

-1 < x ≤ 3 (Divide -5 on both sides)

Note that the signs flip due to dividing by a negative number.

Answer:

[tex]-1<x\leq3[/tex]

Step-by-step explanation:

Let's take two equations from this and them put them back together! So:

9>-5x+4

and

[tex]-5x+4\geq -11[/tex]

For the first one:

9>-5x+4

Subtract 4 from both sides

5>-5x

Then divide by -5 (Remember to change the direction of the sign!):

-1<x

Now onto the second one:

[tex]-5x+4\geq -11[/tex]

Subtract 4 from both sides:a

[tex]-5x\geq -15[/tex]

Then divide by -5 (Remember to change the direction of the sign!):

[tex]x\leq 3[/tex]

Now add the equations back together:

5 + m > 4 or 7m< -35

Answers

Answer:

Solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]

The graph of the inequality is shown in figure attached.

Step-by-step explanation:

We need to Solve each compound inequality [tex]5 + m > 4\: or\: 7m< -35[/tex]

Solving the inequalities

For solving compound inequalities we solve both inequalities simultaneously and find the value of m.

For solving 5+m > 4, we subtract 5 from both sides.

While solving 7m < -35, we divide both sides by 7 to get value of m

Applying these functions we get:

[tex]5 + m > 4\: or\: 7m< -35\\m>4-5\:or\:m<\frac{-35}{7}\\m>-1\:or\:m<-5[/tex]

So, solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]

The graph of the inequality is shown in figure attached.
