Write a polynomial that represents the area of the shaded region.

Answer:

height (h) = 15

Step-by-step explanation:

To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

Answer:

d = 25.12

Step-by-step explanation:

volume = 144 pie cm cubed

h = 9

d = (144 pie cm cubed / 9) / 2

d = 25.12

Answer:

Step-by-step explanation:

Just comparing the given y= +(x-2)^2 + 4 to

                                            y = (x - h)^2 + k

reveals that the vertex is at (h, k):  (2, 4) and that the graph opens up.

The correct graph is the one in the upper left hand area of the illustration.

Answer:

Hello! The answers will be in explanation :D

Step-by-step explanation:

a) You can use a linear regression calculator online to get the equation. You would get the equation: y = 4.87x + 2.28

b) The slope would be 4.87, m is the slope in the slope-intercept equation. The slope represents that for each puppy that is at birth, their adult weight adds 4.87 pounds each time.

c) The value of the correlation coefficient is 0.989. Again, you could always search up a correlation coefficient calculator online and get the same solution I have.

Hope this helps! ^^

Answer:

Part C. Perform a linear regression and interpret the results.

a. Use a calculator to perform a linear regression. Round the values your calculator gives you for a and b to the nearest hundredth. (2 points)

y = ___4.87____x + ____2.28___

b. What is the slope of the regression equation? What does this mean in terms of birth weight and adult weight? (2 points)

The slope of the regression equation is 4.87. This means that as the puppies get older they will get heavier at a rate of 7.87

c. What is the value of the correlation coefficient? (1 point)

The Correlation coefficient has a value of 0.989

Step-by-step explanation:

supplementary means the angles add up to 180

Answer:

To find the perimeter of a polygon, you just have to add the values of each side.

For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

Answer:

The leading coefficient, a.

Step-by-step explanation:

In a quadratic equation:

y = a*x^2 + b*x + c

The leading coefficient is the coefficient hat that multiplies the variable with the highest power.

In this case, is easy to see that the leading coefficient is a.

We call this the "leading" coefficient because is the coefficient that most impact has on the equation's behavior.

In the case of the quadratic equation, we know that x^2 is always a positive number and is the part that grows faster.

Then if a is a positive number, a*x^2 will be positive, and because this is the part that grows faster, the arms of the parabola will open upwards.

If a is negative, then a*x^2 will be negative, and this will cause that the arms of the parabola open downwards

Then the sign of a defines the direction of the parabola.

And a also defines the width of the parabola.

If a is a really larger number, then

a*x^2 grows really fast

This means that in a small increase of x, we may see a large increase in y, so we will have a "thin" parabola.

On the other hand, if a is really small, a large increase of x will not cause a large increase on y, so we will see a wider parabola.

Then the coefficient a (or variable, depending on which thing are you changing) is the one that controls the parabola's direction and width.

Answer:

Indian system of numeration:

With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.

For instance, a million would be:

= 10,00,000

Distance to moon in Indian numeration = 3,84,014 km

International System of Numeration:

Here a comma separates a maximum of 3 digits. A million here would be:

= 1,000,000

Distance to moon is therefore:

= 384,014 km

Step-by-step explanation:

Answer:

The information we have is:

The boat can hold 170 L of fuel

The boat uses 34L each hour.

With this information, we can find the total amount of time that the boat can be used.

If the boat is used x hours, then it needs:

x*34L of fuel.

And the maximum amount of fuel that the boat can use uis170 L

Then we can solve:

x*34L = 170L

Now we can divide both sides by 34L to isolate x.

x = 170L/34L = 5

This means that the boat can be used for 5 hours.

For any two rational numbers a and b,  

(a+b),(a−b),(b−a) & (a×b) are all rational numbers.

Thus, rational numbers are closed under addition, subtraction and multiplication. (for the first one)

Answer: 56

Step-by-step explanation:

Since we are informed that Isaac’s dad built a shelf for his video games that is 42 inches wide and that each video game is 6/8 inches wide.

The number of video games that Isaac can fit on the shelf will be gotten by dividing the length of the shelf by the width of each video game. This will be:

= 42 ÷ 6/8

= 42 × 8/6

= 56

Therefore, Isaac can fit 56 video games on the shelf.

Answer:

90 km/h

Step-by-step explanation:

To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.
