Calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26
HELP!!!!
Answer:
we get Rate of change = -3
Step-by-step explanation:
We need to calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26
The rate of change can be calculated using slope formula: [tex]Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table, we can take any 2 points
Suppose we take (-1,7) and (2,-2)
We have: [tex]x_1=-1, y_1=7,x_2=2, y_2=-2[/tex]
Putting values in formula and finding rate of change
[tex]Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:change=\frac{-2-7}{2-(-1)}\\Rate\:of\:change=\frac{-9}{2+1}\\Rate\:of\:change=\frac{-9}{3}\\Rate\:of\:change=-3[/tex]
So, we get Rate of change = -3

Here are two circles. Their centers are A and F. What is the same about the two circles?
Both the circle A and F have same radius and diameter.
What is Radius of circle?Any circular object's radius is the measurement from the centre to its outermost border or boundary. A radius is a dimension that applies to spheres, semispheres, cones with circular bases, and cylinders with circular bases in addition to circles.
It is possible to define a circle as the locus of a point moving in a plane while maintaining a constant distance from a fixed point. The radius of a circle is the distance from any point on the circle to its center. The fixed point is referred to as the centre of the circle.
Given:
We have Two circles named A and F.
Now, the radius of circle A is 4cm
So, the diameter of Circle A is 4 x2 = 8 cm
Now, the Diameter of Circle F is 8 cm
Hence, both the circle A and F have same radius and diameter.

Can someone please explain how to do number 9.
Answer:
x<15, probably
Step-by-step explanation:
maybe multiply 2 to each side to eliminate the fraction. so 3x+15<60. subtract 15 to isolate the variable term so 3x<45. divide by 3 to isolate x so x<15. check the work. is the inequality true for all values of x less than 15? let's try the first possible integer value, 14, to be sure. 3(14)+15= 57. so 57/2<30. now 57/2 is 28.5 and 28.5<30 so it seems right

Given that the following is a Rhombus, find the missing sides.
Answer:
AE = 6
AC = 12
BD = 16
AB = 10
Step-by-step explanation:
In a rhombus, which is equilateral, the diagonals bisect each other so,
AE = EC so 6
AC = AE + EC, which is 6+6
BD = ED + EB or 8+8
AB = BC so 10

Calories consumed by members of a track team the day before a race are normally distributed, with a mean of 1,600 calories and a standard deviation of 100
calories. If a normal curve is sketched using these data, what is the range for 3 standard deviations to the right and to the left of the mean?
O 1,400-1,800
O 1,500-1,700
O 1,300-1,900
O 0-3,200
20 POINTS
plz help
Thank you
Answer:
The solution is 1,300-1,900
Step-by-step explanation:
Simply put:
The standard deviation is 100. Because the range is 3 standard deviations, you add and subtract 300 from 1,600 instead of the normal 100.
So,
1,600 - 300 = 1,300
1,600 + 300 = 1,900
So, your answer is the third option: Between 1,300 and 1,900
The correct answer is 1,300 - 1,900.

let f(x) = x^3+3x^2-x-3. Find the polynomial function each of whose roots are two less than the roots of f(x)
Step-by-step explanation:
f(x) = x³ + 3x² - x - 3 = x²(x + 3) - (x + 3)
= (x² - 1)(x + 3) = (x + 1)(x - 1)(x + 3).
The roots of f(x) are x = -3, -1 and 1.
=> The new roots are x = -5, -3 and -1.
=> g(x) = (x + 5)(x + 3)(x + 1) = x³ + 9x² + 23x + 15.
What is the solution to the gaming systems of linear equations 2X plus 3Y equals 13 for a 6+ 6Y equals 14
Answer:
(9/2, 4/3) or just x = 9/2, y = 4/3. (it's the same thing)
Step-by-step explanation:
First, multiply the first equation 2x + 3y = 13 by 2, so that you get 4x + 6y = 26. Now you have the same coefficient for y. Now, subtract the second equation 6y = 8 (i simplified it first) from the first one that is doubled. After that, you would have just one equation, 4x = 18. So x = 18/4 = 9/2. Substitute x to solve for y, and you'd get 4/3.

Answer:
(x, y) = (-6, 8 1/3)
Step-by-step explanation:
The system of equations appears to be ...
2x +3y = 136x +6y = 14Dividing the first equation by 2 gives ...
3x +3y = 7
Subtracting the first equation from this, we get ...
(3x +3y) -(2x +3y) = (7) -(13)
x = -6
Then substituting for x in the first equation, we have ...
2(-6) +3y = 13
3y = 25 . . . . . . . . add 12
y = 25/3 = 8 1/3 . . . . divide by 3
The solution is (x, y) = (-6, 8 1/3).

Urgent Question!!!
Step-by-step explanation:
Coordinates of Point R = (0, y).
We have PR = QR.
=> (-2 - 0)² + (6 - y)² = (9 - 0)² + (3 - y)².
=> 4 + (6 - y)² = 81 + (3 - y)²
=> y² - 12y + 40 = y² - 6y + 90
=> 6y + 50 = 0
=> y = -25/3.
Hence the answer is (0, -25/3).
Coordinates of Point S = (x, 0).
We have PS = QS.
=> (-2 - x)² + (6 - 0)² = (9 - x)² + (3 - 0)²
=> (-2 - x)² + 36 = (9 - x)² + 9
=> x² + 4x + 40 = x² - 18x + 90
=> 22x = 50
=> x = 25/11.
Hence the answer is (25/11, 0).
here,
coordinates of P(-2,3)
coordinates of Q(9,3)
coordinates of R(0,0)
now,
PR=QR
or, 0-(-2)+0-3=(0-9)+(0-3)
or, 2-3= -9-3
or, -1 = -12
