The equations that describe the given circles are:
x^2 + y^2 = 4
x^2 + y^2 = 64
How to get the equations for the circles?
For a circle of radius R, centered at the point (a, b), the equation is:
(x - a)^2 + (y - b)^2 = R^2
In this case, we have two circles, both centered on (0, 0), but one has a radius of 2 units and the other a radius of 8 units, then we have two equations:
x^2 + y^2 = 2^2 = 4
x^2 + y^2 = 8^2 = 64
These are the two equations that describe the given circles.

Joseph's grandparents get him a puppy for his thirteenth birthday, and he names the puppy Bailey. Joseph does a good job taking care of Bailey, and she's growing so fast! When Bailey is 1 month old, she weighs 3 pounds. When she is 3 months old, she weighs 6 pounds. In this relationship, x represents Bailey's age (in months), and y represents her weight (in pounds). Explain why this is not a proportional relationship
Answer:
Step-by-step explanation:
It's not proportional because for every 1 month there's supposed to be 3 pounds, but it shows that when she was 3 months she is 6 pounds soits not proportional because it shows she grows 3 times at first but then by 3 months she grows 1/3

Answer:
2.3333
Step-by-step explanation:
(2+4+6+8) / 4 = 20/4 = 5
Step 2 :
Find the distance between each data and mean.
Distance between 2 and 5 is 3
Distance between 4 and 5 is 1
Distance between 6 and 5 is 1
Distance between 8 and 5 is 3
Step 3 :
Add all the distances :
3+1+1+3 = 8
Step 4 :
Divide it by the number of data :
8 / 4 = 2
2. What is the measure of side KL?
Answer:
KL ≈ 3.6
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan24° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{KL}{KM}[/tex] = [tex]\frac{KL}{8}[/tex] ( multiply both sides by 8 )
8 × tan24° = KL , then
KL ≈ 3.6 ( to the nearest tenth )
Answer:
3.6
Step-by-step explanation:
Using Trigonometry we know;
SOH, CAH, TOA
Therefore we will use TOA as we want to find the opposite which will be
tan=opposite/adjacent
so, opposite=tan(x) times adjacent (rearranged the formula)
which then will be:
tan(24) × 8= 3.561829482
KL=3.6

Because you are given a point and a slope you use what is called the point-slope formula.
y-y₁=m(x-x₁)
[tex]y-4=-2(x--2) \\ y-4=-2x-4\\y=-2x-4+4\\y=-2x[/tex]
How do you solve this?
Step-by-step explanation:
We need to find the demand so the variable x is unknown.
We know that the variable p is 37.55 so we replace that in the equation
[tex]37.55 = 40 - \sqrt{0.01x + 1} [/tex]
Subtract Property
[tex] - 2.45 = - \sqrt{0.01x + 1} [/tex]
Division Property
[tex]2.45 = \sqrt{0.01x + 1} [/tex]
[tex](2.45) {}^{2} = 0.01x + 1[/tex]
[tex]6.0025 = 0.01x + 1[/tex]
[tex]5.0025 = 0.01x[/tex]
[tex]500.25 = x[/tex]

A 500-foot cable is attached to the top of a tower and is stretched tight to a point that is 350 feet away from the base of the tower. What is the angle of depression formed by the cable? A. 34. 9° B. 35. 3° C. 44. 4° D. 45. 6°
The angle of depression formed by the cable is 44°.
The angle of depression is an angle measured downward from a horizontal line to the line of sight between an observer and a point that is below the observer. It is used to describe the angle formed between a horizontal reference line (usually the observer's line of sight) and a line drawn from the observer's eye to a point of interest that is lower in elevation.
According to the question the tower, cable, and path makes a triangle whose
base = 350 feet,
hypotenuse = 500 feet.
Since, cos[tex]\theta[/tex] = [tex]\frac{base}{hypotenuse}[/tex]
= [tex]\frac{350}{500}[/tex]
= [tex]\frac{7}{10}[/tex]
[tex]\theta[/tex] = arccos([tex]\frac{7}{10}[/tex])
= 0.77539749 radians
= 0.77539749 × [tex]\frac{180^o}{\pi}[/tex]
= 0.77539749 × [tex]\frac{180^o}{3.14}[/tex]
= 44.45°
≈ 44°.
Thus, the correct answer is C. 44°.

Lillian has a rectangular garden with an area of 3x² - 10x - 8 square feet. Find the expressions that would represent the length and width of the garden. Make sure you show all your work for full credit.
Answer:
x = 4
x = -2/3
Step-by-step explanation:
3x² - 10x - 8
multiply 3 and -8 which = -24
what 2 factors of -24 that when added make -10
those 2 factors would be -12 and +2
Rewrite the polynomial splitting the middle term using the two factors -12 and 2
3x^2 - 12x + 2x - 8
split it up
3x^2 - 12x
2x - 8
x(3x + 2)
2(x - 4)
pulling out like factors
(x - 4) * (3x + 2)
OR
3 ( x - 12/3 )( x + 2/3 ) = 0
3( x - 4 )( x + 2/3 ) = 0
divide both sides by 3
x = 4
x = -2/3

jada can write 3 1/4 pages in 8 minutes. At this rate, how many pages could jada write in 24 minutes?
Answer:
9 3/4 pages = x
Step-by-step explanation:
[tex]\frac{pages}{minutes} = \frac{pages}{minutes}[/tex] change 3 1/4 to a decimal
[tex]\frac{3.25}{8} = \frac{x}{24}[/tex]
[tex]3.25(24) = 8x[/tex]
[tex]78 = 8x[/tex]
[tex]\frac{78}{8} = x[/tex]
[tex]9.75 = x[/tex]
[tex]9\frac{3}{4} =x[/tex]
working with the fraction
3 1/4 /8 = x/ 24
3 1/4 (24) = 8x
13/4 (24) = 8x
316/4 = 8x
78 = 8x
78/8 = x
9 3/4 = x

Step-by-step explanation:
[] The three different parts show us this will be a quadratic function.
-> y = ax² + bx + c
-> This is a parabola, normally "opening up" towards the top
[] The plain x² shows there will be no compression or stretch scale factor
-> This is the "a" value
[] The -4x shows that the graph will have a linear slope through it of -1/4
-> This is the "b" value
-> See the second image attached
[] The 1 shows that the graph will have a y-intercept of (0, 1)
-> This is the "c" value
Please note that the "parent function" is y = x²

The depth of the water at the end of a pier changes periodically along with the movement of tides. On a particular day, low tides occur at 12:00 am and 12:30 pm, with a depth of 2. 5 m, while high tides occur at 6:15 am and 6:45 pm, with a depth of 5. 5 m. Let t = 0 be 12:00 am. Graph the equation equationthat models the situation using a graphing calculator and use it to answer the following questions. How many times during this day is the depth at the end of the pier equal to 4 meters? 2 times 3 times 4 times 5 times.
we get the graph of cosine function.
Here we have given that the low tides occur at a depth of 2.5 m at 12:00 am and 12:30 pm,
separated by the period of T = 12.5 hours. and also high tides occur at a depth of 5.5 m at 6:15 am and 6:45 pm,
separated by a period of T = 12.5 hours.
From the diagram we have use the value of t tor finding the amplitude
So,
What is the formula of amplitude ?
(max+min)/2
Therefore,
The amplitude is,
[tex]\frac{1}{2} (5.5 - 2.5) = 1.5 m.[/tex]
x(0)=2.5 and x(T/2)=5.5
from the diagram we can say that the function is periodic
[tex]x(t)=-1.5cos(\frac{2\pi t}{12.30} )+4[/tex]
Therefore,
we get the graph of cosine function.
