Answer:

A = pi x r²

Step-by-step explanation:

pi = 3.14      r : the radius  

Answer:

I think it's the second one A = pi r2

To find the missing angle measurement, we will use the Angle Sum Property to create an algebraic equation that can solve for a missing angle given two angles in a right triangle.

We are given an angle of 27º and 90º (refer to the square in the bottom right-hand corner.

We know that all of the angles in a triangle must add up to 180º using the Angle Sum Property.

Create an equation to find the missing value.

[tex]27 + 90 + x = 180[/tex]

Combine the constants on the left side of the equation.

[tex]27 + 90 + x = 180[/tex]

[tex]117 + x = 180[/tex]

Subtract 117 from both sides of the equation.

[tex]117 - 117 + x = 180 - 117[/tex]

[tex]\boxed{x = 63}[/tex]

The final answer is x = 63º.

Answer:

63 degrees

Answer:

a. From x = -2 to x = 0, the average rate of change for both functions is negative

d. The quadratic function, y = x², has an x-intercept at the origin

Step-by-step explanation:

From x = -2 to x = 0, the rate of change is negative because both functions are going in a downward slope. The quadratic function y = x² touches the x-axis right at (0, 0), meaning it has an x-intercept at the origin.

The second answer is incorrect because y = x² does not intersect the other parabola at (2, 3). The third is incorrect because y = x² + 3 does not even touch the x-axis. The fifth is incorrect because the rate of change is negative, not positive. Finally, the sixth is incorrect because y = x² + 3 does not intersect the other parabola at (2, 7). Hope this helps! Feel free to ask any questions!

Answer:

Um.. well I don't know what is your question, but I think you meant square root and the answer is 7 because it is a perfect square.

Step-by-step explanation:

Answer: x²-22/3x+7/3=0

Step-by-step explanation:

For the solutions to be 1/3 and 7, the equations must be x-1/3 and x-7 because they will equal zero.

(x-1/3)(x-7)=???

x·x= x²

x·(-1/3)=(-1/3x)

x·(-7)=(-7x)

(-7)·(-1/3)=7/3

x²-1/3x-7x+7/3=0 ⇒ x²-22/3x+7/3=0

Since this is in the quadratic form (ax²+bx+c), this is the final answer.

Hope that this helped! Have a great day!!

Answer:

A

Step-by-step explanation:

histogram's report ranges

ex.

60 people in 20 - 29

20 people in 30 - 39

10 people in 40 - 49

A) Histogram is suitable for this data, as large number of scores are reported as ranges

Histogram is a form of graphical representation of data, presenting a group of data points in particular ranges.

Dot plot presents data simply by number of dots, on various data points.

In this case : students scores are not in individual numerical units, but in range. Scores : 20 to 29 ... 60 to 69

So, Histogram is suitable in this case, and not Dot Plot

I think that to answer this you need to calculate the total amount of probibilities divided by the number of pets which is 3

Answer:

The first 2 on top is not a function. The 3rd one on top and the bottom 2 are functions.

Step-by-step explanation:

The x-value cannot have more than 1 y-value or else when you plot the points on the graph, it doesn't meet the vertical line test. The vertical line test indicates whether or not the graph is a function. Different x-values can have the same y-value.

Function examples: (3,-4), (5,0), (0,-4), (1,2)

Not a Function examples: (0,8), (2,-1), (0,-2), (-5,3)

Answer:

Step-by-step explanation:

First one is 19. The work is 7+7+5=19

Second one is 22.  The work is  12+5+5=22

Third one is 15.  The work is 3+3+3+3+3=15

Answer:

I got 5 for you, the answer is x+4=10 or x+2=10, that's the error. You don't seperate them in parenthises like that, you have to multiply them together. This means it has to be x+4 times x+2. I'll try the others too, but no guarantess here.

Answer:

104 m

Step-by-step explanation:

First, find the area of the rectangle, getting 8m * 10m, or 80m

Next, add the area of the triangle, 1/2 * 6m * 8m, or 24m.

Add them together and you get a total of 24 meters.

I = $ 2000

P = $ 5000

r = 8%

[tex]I = P * \frac{r}{100}*t\\\\t =\frac{ I * 100}{P*r}\\\\t =\frac{2000*100}{5000*8}\\\\ = 5[/tex]
