  451. No, the angles are wrong.

Step-by-step explanation:

450. AB = 15, BC = 10, and CD= 7. Find the length DA.

  This cannot be done without additional information about the sort of figure that ABCD is. If these are points on a line segment, we need to know their order. If these are points on a quadrilateral, we need to know its description in more detail.

If these are points ordered ABCD on a line, then AD = 15+10+7 = 32.

The difference is:

Answer:

- 1 and 7

Step-by-step explanation:

to find h(0) substitute x = 0 into h(x)

h(0) = 4(0) - 1 = 0 - 1 = - 1

to find h2) substitute x = 2 into h(x)

h(2) = 4(2) - 1 = 8 - 1 = 7

Answer:

To find the pattern we need to subtract the given integers.

Thus, we ned to subtract the 2nd term from the 1st rems and 3rd from 2nd and so on...

⇒(-3)-(-1)=-2

Now,

(-1)-3= -4

Now,

3-9=-6

Now the defferences between the given terms are, -2, -4, -6

So here we see the difference between the terms are mutiples of 2 increasing according to their places, but interestingly we are not actually subtracting from any of the terms to get the next number, we are adding as you can see it in the last 2 terms 3&9 as only when we add 6 to 3 we get 9 and not when we subtract, so the pattern will be,

The derivative of the function is

A) dw/dz=z^5 (7z-18)

B) dh/dx=192x^11+36x^5-6x^2+19

C) dy/dx=24x^2-38x-15

In mathematics, the derivative of a function measures the sensitivity to change of the function value with respect to a change in its argument. It is the rate of change of a function with respect to a variable.

A) w = z^7 – 3z^6 + 14

dw/dz=7z^6-18z^5

dw/dz=z^5 (7z-18)

B) h(x) = 16x^12 + 6x^6 – 2x^3 + 19x – 7

dh/dx=192x^11+36x^5-6x^2+19

C) y = (8x + 5)(x^2 – 3x)

dy/dx=  d/dx  [8x+5]*〖(x〗^2-3x)+(8x+5)*d/dx[x^2-3x]

dy/dx=(8*  d/dx  [x}+d/dx[5])*〖(x〗^2-3x)+(8x+5)*(d/dx[x^2]-3 d/dx[x])

dy/dx=(8*1+0)(x^2-3x)+(8x+5)(2x-3*1)

dy/dx=8(x^2-3x)+(2x-3)(8x+5)

dy/dx=24x^2-38x-15

Note: The question is incomplete. The complete question probably is: Find the derivative of the following function: A) w = z^7 – 3z^6 + 14 B) h(x) = 16x^12 + 6x^6 – 2x^3 + 19x – 7 C) y = (8x + 5)(x^2 – 3x).

Answer: It is the distance that -5 is form 0 on the number line

Step-by-step explanation:

We can define the absolute value of any number:

IxI as:

"The distance between the point x and the origin in the coordinate axis"

If we are in one dimension, x is just a value, and the coordinate axis will be a number line.

Then we could rewrite this as:

"is the distance between the value x and the 0 in the number line"

So:

IxI = x if x > 0

IxI = -x if x < 0.

Then:

I -5 I

Is the distance between the number -5, and the 0 in the number line, and this is:

I - 5 I = 5.

4.25 x 13 = 55.25

4.25 x 12 = 51

13.70 x 92 = 1260.4

3.28 x 130 = 426.4

The weight of the Avery's lunch box using given weights is equal to 0.92 pounds (rounded to two decimal places).

Total weight of the backpack= 2 2/3 pounds

                                                = 8/3 pounds

The weight of the each book =7/8 pounds.

Let x be the weight of the lunch box in pounds.

An equation that represents the total weight in Avery's backpack,

2(7/8) + x = 8/3

To solve for x, simplify and solve for x,

⇒14/8 + x = 8/3

Multiplying both sides by 24 the least common multiple of 8 and 3 to clear the fractions,

⇒42 + 24x = 64

Subtracting 42 from both sides,

⇒24x = 22

Dividing both sides by 24,

⇒x = 22/24

Simplifying the fraction,

⇒x = 11/12

     =  0.92 pounds (rounded to two decimal places).

Therefore, the  weight of the lunch box is equal to 0.92 pounds (rounded to two decimal places).

Monica still needs to gain 167/24 pounds or approximately 6.96 pounds to reach her goal of being able to donate blood.

To calculate how many more pounds Monica still needs to gain, we need to add up the weights gained and subtract the weight lost.

Weight gained in the first week: 1/3 pound

Weight gained in the second week: 1/6 pound

Weight gained in the third week: 1/6 pound

Weight gained in the fourth week: 5/8 pound

Weight lost in the fifth week: 1/4 pound

Let's add up the weights gained:

1/3 + 1/6 + 1/6 + 5/8 = (8/24) + (4/24) + (4/24) + (15/24) = 31/24 pounds

Now, let's subtract the weight lost:

31/24 - 1/4 = (31/24) - (6/24) = 25/24 pounds

Monica has gained a total of 25/24 pounds. Since she needs to gain 8 pounds to be able to donate blood, she still needs to gain an additional:

8 - (25/24) = (192/24) - (25/24) = 167/24 pounds

Answer:

We all watched NASA's space shuttle videos where the announcer names the countdown "T-5 hours". That means that there are 5 hours till the liftoff. Why not input your own data and see how many hours left till your final countdown? Use this time calculator for making fast and effective hours from now calculator.

Step-by-step explanation:

To calculate the work required to pull the rope up to the top of the building, we need to first find the total weight of the rope.

The rope weighs 3 pounds per 20 feet, so for 200 feet, it weighs:
(3 pounds / 20 feet) x 200 feet = 30 pounds
Therefore, the total weight of the rope is 30 pounds.
To lift the rope up to the top of the building, we need to overcome the force of gravity acting on the rope. The force of gravity is equal to the weight of the rope, which is 30 pounds.
To calculate the work required, we can use the formula:
Work = Force x Distance
In this case, the force is 30 pounds and the distance is 200 feet (the height of the building).
So,
Work = 30 pounds x 200 feet = 6,000 foot-pounds
Therefore, it takes 6,000 foot-pounds of work to pull the rope up to the top of the building.

You are at the top of a 200-foot tall building, and a rope that weighs 3 pounds per 20 feet dangles from the roof, with the lower end touching the ground. We need to find how much work it takes to pull the rope up to the top of the building.
First, let's determine the weight of the entire rope:
Since the rope weighs 3 pounds per 20 feet, we need to find out how many 20-foot sections are in a 200-foot rope.
200 feet / 20 feet = 10 sections
Now, multiply the number of sections by the weight per section:
10 sections * 3 pounds = 30 pounds (total weight of the rope)
Next, we need to calculate the work required to pull the rope up. Work (W) is defined as force (F) multiplied by distance (d):
W = F * d
In this case, the force required is equal to the weight of the rope (30 pounds) and the distance is the height of the building (200 feet):
W = 30 pounds * 200 feet = 6,000 foot-pounds
So, it takes 6,000 foot-pounds of work to pull the rope up to the top of the 200-foot tall building.

The calculation for the P-value of a hypothesis test about a population mean is based on the mathematical properties of the sampling distribution of the statistic. Option C is the correct answer.

The P-value, in hypothesis testing, is the probability of observing a test statistic at least as extreme as the one calculated from the observed data, assuming the null hypothesis to be true. The smaller the P-value, the less likely it is that the results observed are due to chance alone.

The significance level, alpha (α), is the threshold used to determine whether a P-value is statistically significant. A P-value of less than the significance level suggests that the null hypothesis should be rejected, and the data are statistically significant. To compute the P-value, one must first calculate the test statistic from the sample data.

The sampling distribution of the statistic under the null hypothesis is then employed to calculate the P-value. If the P-value is less than or equal to the significance level, we can reject the null hypothesis. If the P-value is greater than the significance level, we fail to reject the null hypothesis.

Therefore, c is correct.

Based on the calculations, the sum of the areas of the rectangles is equal to: A. 0.25 square unit.

Mathematically, the area of a rectangle can be calculated by using this formula;

A = LW

Where:

By critically observing the figure (see attachment), we can logically deduce the following information:

Width of rectangle A = 2 units

Width of rectangle B = 2 units.

Width of rectangle C = 4 units.

Next, we would determine the length and area of each of the rectangle.

The length of the first rectangle is given by:

Length of rectangle, y = 3^-x

Length of rectangle, y(0) = 3⁻⁰ = 1 units.

Length of rectangle, y = 3^-x

Length of rectangle, y(2) = 3⁻² = 0.11 unit.

Area of first rectangle = 2(0.11)

Area of first rectangle = 0.22 square unit.

For the second rectangle, we have:

Length of second rectangle, y = 3^-x

Length of second rectangle, y(4) = 3⁻⁴ = 0.012 unit.

Area of second rectangle = 2(0.012)

Area of second rectangle = 0.025 square unit.

For the third rectangle, we have:

Length of third rectangle, y = 3^-x

Length of third rectangle, y(8) = 3⁻⁸ = 0.00015 unit.

Area of third rectangle = 4(0.00015)

Area of third rectangle = 0.0006 square unit.

Now, we can calculate the sum of the areas of the rectangles:

Total area = 0.22 square unit + 0.025 square unit + 0.0006 square unit.

Total area = 0.246 ≈ 0.25 square unit.

Total area of rectangle = 0.25 square unit.

The first step used in the elimination method is to align the coefficients of one chosen variable in both equations.

To solve a system of equations using elimination, the first step is to align the coefficients of one variable in both equations.

This involves multiplying one or both equations by a constant to create equal coefficients for the chosen variable.

This allows for easy elimination when adding or subtracting the equations.

Once the coefficients are aligned, you can proceed to the next step of eliminating one variable by adding or subtracting the equations.

After eliminating one variable, the resulting equation will have only one variable, which can then be solved for its value.

This value can be substituted back into either of the original equations to find the value of the other variable. Finally, the solution to the system of equations is the values of both variables.

In conclusion, the first step used in the elimination method is to align the coefficients of one chosen variable in both equations.
