The question refers to the plot of the plate's function of the angle of inclination. When the hot side is tilted both upward and downward over the range of +90°, the discontinuous formulas must be used in different ranges of 0.

It refers to the plot of the function of the angle of inclination of a plate. It is a graph that shows the relationship between the angle of inclination and the plate's function. A plate is tilted on its hot side both upward and downward over a range of +90°. The graph shows that different discontinuous formulas are needed for different ranges of 0. A discontinuous formula refers to a formula that consists of two or more parts, each with a different equation. The two or more parts of a discontinuous formula have different ranges, such that each range requires a different equation. These formulas are used in cases where the same equation cannot be applied throughout the entire range.

The expression "x - y + z" can be simplified and rearranged using the associative property and commutative property of addition. Let's break it down step by step:

1. x - y + z

According to the associative property of addition, the grouping of terms does not affect the result when only addition and subtraction are involved. Therefore, we can choose to group "y" and "z" together:

2. x + (-y + z)

Next, using the commutative property of addition, we can rearrange the terms "-y + z" as "z + (-y)":

3. x + (z + (-y))

Now, we have the expression "x + (z + (-y))". According to the associative property of addition, we can group "x" and "z + (-y)" together:

4. (x + z) + (-y)

Finally, we can rewrite the expression as "(x + z) - y", which is equivalent to "(x - y) + z":

5. (x + z) + (-y) = (x - y) + z

Therefore, "x - y + z" is indeed the same as both "x - (y + z)" and "(x - y) + z" due to the associative and commutative properties of addition.

Answer:

5.6ft squared

Step-by-step explanation:

4x7 = 28 divided by 5 which is 5.6

1. Factorize the numerator:

x¹⁰ - 1 = (x - 1) (x⁹ + x⁸ + x⁷ + … + x² + x + 1)

Then

\(\displaystyle \lim_{x\to1} \frac{x^{10}-1}{x-1} = \lim_{x\to1} (x^9+x^8+\cdots+x+1) = \boxed{10}\)

2. Recall that

\(\displaystyle \lim_{x\to0} \frac{1-\cos(x)}x = 0\)

Then

\(\displaystyle \lim_{x\to0} \frac{1-\cos(2x)}x = 2 \lim_{x\to0} \frac{1-\cos(2x)}{2x} = 2\times0 = \boxed{0}\)

3. If f(x) = x² + 2x, then f'(x) = 2x + 2 and f''(x) = 2. This follows from the power rule for differentiation.

If you wish to show this using the definition, then

\(\displaystyle f'(x) = \lim_{h\to0} \frac{f(x+h) - f(x)}h\)

\(\displaystyle f'(x) = \lim_{h\to0} \frac{\left((x+h)^2 + 2(x+h)\right) - \left(x^2+2x\right)}h\)

\(\displaystyle f'(x) = \lim_{h\to0} \frac{x^2 + 2xh + h^2 + 2x + 2h - x^2 - 2x}h\)

\(\displaystyle f'(x) = \lim_{h\to0} \frac{2xh + h^2 + 2h}h\)

\(\displaystyle f'(x) = \lim_{h\to0} (2x + h + 2)\)

\(\displaystyle f'(x) = 2x+2\)

and

\(\displaystyle f''(x) = \lim_{h\to0} \frac{f'(x+h) - f'(x)}h\)

\(\displaystyle f''(x) = \lim_{h\to0} \frac{(2(x+h)+2) - (2x+2)}h\)

\(\displaystyle f''(x) = \lim_{h\to0} \frac{2x + 2h + 2 - 2x - 2}h\)

\(\displaystyle f''(x) = \lim_{h\to0} \frac{2h}h\)

\(\displaystyle f''(x) = \lim_{h\to0} 2\)

\(\displaystyle f''(x) = 2\)

Answer:

SA = 10,800 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 40

w = 60

h = 30

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 60(40) + 30(40) + 30(60) )

SA = 2 ( 2400 + 1200 + 1800 )

SA = 2 ( 5400 )

SA = 10,800 ft²

Answer:

42 minutes

Step-by-step explanation:

6x7=42

Answer:

1) 3 people do 4 walls in 32 minutes

We make the assumptions that all people work at the same rate and each person starts and finishes at the same time. Since there are 3 people, each person does 1/3 of the total work. Therefore each person finishes their portion of the job in 32 minutes

2) 3 * 1/3 = 1 person does 4 * 1/3 = 4/3 walls in 32 minutes

The unit rate (the rate for 1 person to do 1 wall) is as follows

3) 1 person does 4/3 * 3/4 = 1 wall in 32 * 3/4 = 24 minutes

Since we need 4 people to do 7 walls then 1 person needs to do 1/4 of the work. So the following is true

4) 4 * 1/4 = 1 person does 7 * 1/4 = 7/4 wall

As we said before in #3

1 person does 1 wall in 24 minutes

So we conclude

5) 1 person does 1 * 7/4 = 7/4 walls in 24 * 7/4 = 42 minutes

And finally

6) 1 * 4 = 4 people do 7/4 * 4 = 7 walls in 42 minutes

Answer:

Answer:

A ≈ 28.5

Step-by-step explanation:

a, b, c

P = a + b + c

Semiperimeter s = \(\frac{a+b+c}{2}\)

A = \(\sqrt{s(s-a)(s-b)(s-c)}\)

~~~~~~~~~~~~~~~

\(P_{ABC}\) = 4.3 + 2.89 + 6.81 = 14

s = 14 ÷ 2 = 7

\(A_{ABC}\) = \(\sqrt{7(7-4.3)(7-2.89)(7-6.81)}\) = √14.75901 ≈ 3.84

\(P_{BCD}\) = 8.59 + 7.58 + 6.81 = 22.98

s = 22.98 ÷ 2 = 11.49

\(A_{BCD}\) = \(\sqrt{11.49(11.49-8.59)(11.49-7.58)(11.49-6.81)}\) = √609.7343148 ≈ 24.6928

\(A_{ABCD}\) = 3.84 + 24.6928 ≈ 28.5

That's an awful lot of points to give away. Ten or 15 should be enough.

Completing the square.

1. First of all you can find the minimum or maximum immediately.

2. Second it cuts out the need to use the givens (a, b, c) in the quadratic formula which can at times be very cumbersome.

3. It gives you the opportunity to estimate the x and y roots without calculating them. Estimating on a test is a very valuable asset.

There are 256 possible outcomes for the string of 8 heads/tails that can be produced when flipping a coin eight times.

When a coin is flipped eight times, there are two possible outcomes for each individual flip: heads or tails.

Since each flip has two possibilities, the total number of possible outcomes for eight flips can be calculated by multiplying the number of possibilities for each flip together.

Therefore, the number of possible outcomes for eight coin flips is:

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 2^8 = 256

we can conclude the limit limx→1f(x) does not exist.

What do you mean by limit?

A limit is a mathematical notion that is founded on the idea of closeness. It is mostly used to give values to some functions at positions when none are defined in a way that is consistent with values close by.

According to the limit   limx→1−f(x)=3.

Answer:

Yes and no.  It depends on how you set up the problem.  You can set it up as an addition or a subtraction problem.  As a subtraction problem you would use zero pairs, but it you rewrote the expression as an addition problem then you would not need zero pairs.

Step-by-step explanation:

You can:

You can add 7 zero pairs.

_ _ _ _ _ _ _ _ _ _ _  The 4 negative and 7 zero pairs.  

            + + + + + + +

I added 7 zero pairs because I am told to take away 7 positives, but I do not have any positives so I added 7 zero pairs with still gives the expression a value to -4, but I now can take away 7 positives.  When I take the positives away, I am left with 11 negatives.

_ _ _ _ _ _ _ _ _ _ _.

I can rewrite the problem as an addition problem and then I would not need zero pairs.

- 4 - 7 is the same as -4 + -7  Now we would model this as

_ _ _ _

_ _ _ _ _ _ _

The total would be 7 negatives.

Answer:

B) Is the answer.

Step-by-step explanation:

If you have 15 quarters and 32 pennies, you have more than twice the amount of pennies that you do quarters. There is a small chance that it could be a dime or a nickel but this is unlikely. The chance of a quarter and penny falling out is much greater than a dime or nickle.

Answer:

-24x^4 + 16x^3

Step-by-step explanation:

Because exponents of a variable rely on an exponential change rather than a linear change, x^4 and x^3 are not like terms and cannot be combined. A simpler explanation is this:

2^4 + 4^8

You can't add these values, you need to simplify the exponents first. There is no way to add exponents this way without first simplifying them. So if you use variables instead of constants, simplifying the exponents is impossible and thus adding an x^4 term and x^3 term is impossible.

It really comes down to how much you can simplify it without being able to add both terms. Fortunately for you, it's really simple here. Since you're subtracting a negative, you're adding a positive! So:

-24x^4 - -16x^3 = -24x^4 + 16x^3

Answer: y = 2(x + 2)² - 5

Step-by-step explanation:

          We are going to use the completing the square method to transform this quadratic equation from standard form to vertex form.

Given:

     y = 2x² + 8x + 3

Factor the 2 out of the first two terms:

     y = 2(x² + 4x) + 3

Add and subtract \(\frac{b}{2} ^2\):

     y = 2(x² + 4x + 4 - 4) + 3

Distribute the 2 into -4 and combine with the 3:

     y = 2(x² + 4x + 4) - 5

Factor (x² + 4x + 4):

     y = 2(x + 2)² - 5

The series -15+(-10)+(-5)+0+...  is a converge series

How to find convergent and divergent series?

A series or sequence is convergent if the terms are approached to infinity, but it is divergent if the terms never become constant  and continue to increase or decrease, and never approach to infinity.

Using the series -15+(-10)+(-5)+0+...

There is a constant addition of +5 to the terms

+15-5=(-10)

(-10)+5=-5

(-5)+5=0

(0)+5=5,

Using the parameters, the series is convergent and will continue to increase to infinity as +5 is added to all the terms.

In conclusion, convergent series have terms to infinity while divergent series have no terms to infinity.

Answer:

X=7,-4

Step-by-step explanation:

-3=(37-3x)^(1/2)-x

Add x to each side

X-3=(37-3x)^(1/2)

Change radical to root

X-3=sqrt(37-3x)

Square each side

(X-3)^2=37-3x

Expand the left side: (x-3)*(x-3)=x^2-6x+9

X^2-6x+9=37-3x

Add 3x to each side

X^2-3x+9=37

Subtract 9 from each side

X^2-3x=28

Make it =0: subtract 28 from each side

X^2-3x-28=0

Convert to product form (a)*(b)=0 so that by making either a or b zero you solve the equation. What two numbers add to -3 and multiply to -28? -7 and 4. So we get (x-7)*(x+4).

(X-7)*(x+4)=0

Now we just make x-7=0 or x+4=0.

(7)-7=0 or (-4)+4=0

X=7 or X=-4.
