A circle is drawn on the (x,y) coordinate plane so that the center is at the point (-3,0). If the radius of the circle is 5, then each of the following points lie on the circle's circumference EXCEPT:
Answers
Answer:
2,5
Step-by-step explanation:
since radius is 5
each point lies on the circumference that has 5 or -5 in its y coordinates must have -3 in its x coordinate because -3 is the center
then option number 1 is incorrect
second option is correct , -3 + ( -5 ) = -8
third option is correct, -3 + 5 = 2
fourth is correct, -3 is the center and 5 steps on y axis
fifth is the same as fourth but opposite direction
so the first one is the exception

#6 find the slope in the graph MULTIPLE CHOICE
Answers
I'm assuming problem 6 is the graph on the right.
If so, then the slope is 1/2
Start at a point like (0,-1) which is the y intercept. Move up 1 and to the right 2 to arrive at (2,0) which is the x intercept.
The movement pattern "up 1, right 2" determines the slope directly
slope = rise/run = 1/2
rise = 1 = go up 1
run = 2 = go to the right 2
------------------------------
You could also pick two points from the blue line, then use the slope formula. If we picked (0,-1) and (2,0), then
m = (y2-y1)/(x2-x1)
m = (0-(-1))/(2-0)
m = (0+1)/(2-0)
m = 1/2

A rectangle is 12 cm longer than it is wide. If its length and width are both decreased by 2 cm, its area is decreased by 108 cm². Find its original dimensions.
Answers
Let the width be "x" cm.
Then the length is "x+12" cm
And the area = x(x+12) = x^2+12x cm^2
----------------------------
Change the dimensions:
width = "x-2" cm
length = "x+10" cm
New area = (x-2)(x+10) = x^2 + 8x - 20 cm^2
------------------
Equations :
Old area - New area = 108 cm^2
x^2+12x -(x^2 + 8x - 20) = 108
4x + 20 = 108
4x = 88
x = 22 cm (original width)
x+12 = 24 cm (original length)

Average rate of change = -4
Step-by-step explanation:

-8 ≤ x ≤ -3 or [-8, -3] in interval notation
Average rate of change of the function can be solved using the formula:
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( b \right) -f \left( a \right) }{ b-a }[/tex]
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ -3 - (-8) }[/tex]

[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ 5 }[/tex]
Substitute x = -3 to the given function for f(-3) and x = -8 for f(-8)
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ f \left( -3 \right) -f \left( -8 \right) }{ 5 }[/tex][tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ { \left[( -3 \right) }^{ 2 } +7 \left( -3 \right) +10]- { \left[( -8 \right) }^{ 2 } +7 \left( -8 \right) +10] }{ 5 }[/tex]
[tex]\mathrm{Average\:rate\:of\:change} = \dfrac{ [9-21+10]-[64-56+10] }{ 5 }[/tex]

a circular pool has a circumference of 28 feet what is the radius of the pool in feet
Answers
Answer:
The formula for circumference of s circle is pi x diameter.
If the circumference is 28 we can divide it by pi to get the Diameter.
28/ pi = 8.9126768131461388030574907488608042739297 rounded to 8.91 (2dp)
The radius is half of the diameter, so this means 8.91 / 2 = 4.46 ft (rounded to 2dp)
Use the leading coefficient and degree of the polynomial function f(x) = x3 – 7x2 + 10x to determine the end behavior of its graph. Select all the correct statements. A. As x → ∞, y → ∞. B. As x → ∞, y → −∞. C. As x → −∞, y → ∞. D. As x → −∞, y → −∞. E. As x → ∞, y → 0.
Answers
Given:
The function is
[tex]f(x)=x^3-7x^2+10x[/tex]
To find:
The end behavior of its graph.
Solution:
We have,
[tex]f(x)=x^3-7x^2+10x[/tex]
Here, leading coefficient is 1 which is positive and degree of function is 3 which is odd.
For odd degree and positive leading coefficient, the end behavior is
[tex]f(x)\to \infty\text{ as }x\to \infty[/tex]
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
Using this, we get
[tex]\text{As }x\to \infty, y\to \infty[/tex]
[tex]\text{As }x\to -\infty, y\to -\infty[/tex]
Therefore, the correct statements are A and D.
We want to study the end behavior of the given polynomial.
The two correct statements are A and D.
As x → ∞, y → ∞As x → −∞, y → −∞The polynomial is:
f(x) = x^3 - 7*x^2 + 10*x.
We can see that the degree of this polynomial is odd, this means that the behavior on the negative side is opposite to the one in the positive side.
In this case, the leading coefficient is one, so it is positive. This will mean that, for large positive values of x, f(x) will be positive.
For large (in absolute value) negative values of x, f(x) will be negative.
Then the end behavior is given by:
As x → ∞, y → ∞As x → −∞, y → −∞So the two correct statements are A and D.

The perimeter of the triangle below is 27 cm. Find the measure of the shortest and the
longest sides.
X
2x
3x – 3
Answers
Answer:
Measure of the shortest side is 5 cm
Measure of the longest side is 12 cm
Step-by-step explanation:
Given:
Perimeter of ∆ = 27 cm
Side lengths of ∆: x, 2x, and 3x - 3
Required:
Measure of the shortest side and measure of the longest side.
SOLUTION:
Sum of all sides of the ∆ = Perimeter
[tex] x + 2x + (3x - 3) = 27 [/tex]
Solve for x
[tex] x + 2x + 3x - 3 = 27 [/tex]
Collect like terms
[tex] 6x - 3 = 27 [/tex]
Add 3 to both sides
[tex] 6x = 27 + 3 [/tex]
[tex] 6x = 30 [/tex]
Divide both sides by 6
[tex] x = \frac{30}{6} [/tex]
[tex] x = 5 [/tex]
Length of each side of the ∆:
x = 5 cm
2x = 2(5) = 10 cm
3x - 3 = 3(5) - 3 = 15 - 3 = 12 cm
Measure of the shortest side is 5 cm
Measure of the longest side is 12 cm
