The center of a circle is (3, 2) and a point on the circle is (5, -2). Find the radius and write the equation for the circle.
Answers
Answer:
r = [tex]2\sqrt{5}[/tex]
[tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Is this a live test question or a homework question?
Step-by-step explanation:
the radius is the distance between (3, 2) and (5, -2)
[tex]r^{2}[/tex] = [tex]{(3 - 5)^{2} + (2 + 2)^{2} }[/tex]
= [tex](-2)^{2} + 4^{2}[/tex]
= 4 + 16 = 20
r = [tex]\sqrt{20 } = 2\sqrt{5}[/tex]
Equation of circle: [tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Answer:
Radius: [tex]2\sqrt{5}[/tex]
Equation of circle: [tex](x-3)^2+(y-2)^2=20[/tex]
Step-by-step explanation:
The radius of a circle is equal to the distance between the center of the circle and any point on the circle. Therefore, we have:
[tex]r=\sqrt{(5-3)^2+(2-(-2))^2},\\r=\sqrt{2^2+4^2},\\r=\sqrt{20}=\boxed{2\sqrt{5}}[/tex]
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex].
What we know:
radius of [tex]2\sqrt{5}[/tex] center at [tex](3, 2)[/tex]Substituting known values, we get:
[tex](x-3)^2+(y-3)^2=(2\sqrt{5})^2,\\\boxed{(x-3)^2+(y-2)^2=20}[/tex]

If the length between points on a map is 6 inches, 8 inches, and 9 inches, and the scale is one inch equals 5 miles, find
the distances in miles
12.16 and 18 miles
11, 13 and 14 miles
30,40 and 45 miles
Answers
Given:
The length between points on a map is 6 inches, 8 inches, and 9 inches.
The scale is one inch equals 5 miles.
To find:
The distances in miles.
Solution:
The given scale is:
1 inch = 5 miles
Using this scale, we get
6 inches = 6 × 5 miles
= 30 miles
8 inches = 8 × 5 miles
= 40 miles
9 inches = 9 × 5 miles
= 45 miles
The distance is miles are 30, 40, 45 miles.
Therefore, the correct option is C.
Find the rate of change from the table.
Answers
==================================================
We're asked to find the slope:
m = slope
m = (y2-y1)/(x2-x1)
m = (50-20)/(4-2)
m = 30/2
m = 15
The rate of change is 15. Each time x goes up by 1, y increases by 15.
slope = rise/run = 15/1
rise = 15, run = 1
I used the middle two columns of the table, but you could use any two columns you want. I subtracted the y values together to get the change in y, which is the rise. The change in x, aka run, is the difference in x values. You must subtract the values in the same order. If done in the wrong order, you might get -15 as the incorrect answer.
What is the equation, in standard form, of a circle with center (−5, 8) and radius 5?
Enter your answer by filling in the boxes.
Answers
Answer:
( x + 5 )² + ( y - 8 )² = 25
Step-by-step explanation:
Standard form for the equation of a circle - ( x - h )² + ( y - k )² = r²
Where r = radius and Center is located at ( h , k )
We are given that the center is at ( -5 , 8 )
Thus, h = -5 and k = 8
We are also given that the radius = 5
Thus, r = 5
Now we just plug all of the given values into the standard form equation
( x - (-5))² + ( y - 8 )² = 5²
*simplify*
in - ( - 5 ) the two negative sign cancel out and it turns into + 5
5² = 25
Thus, the equation is ( x + 5 )² + ( y - 8 )² = 25

Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
Answer:
Step-by-step explanation:
If it went from f(x) ⟹ f(0), that means that x=0.
So, you would plug in 0 for x in f(x)=-8(2)^x-12.
After plugging in the value of x, x=0, into the equation, you should have
f(0)=8(2)^0-12
Now, we are solving for f(0) (or f(x)).
You would use PEMDAS to solve this:
P-PARENTHESIS
E-EXPONENT
M-MULTIPLICATION
D-DIVISION
A-ADDITION
S-SUBTRACTION
There are no parenthesis
there are exponents,
(2)^0 and that =1
so we have f(0)=8(1)-12
there is multiplication, 8(1) which =8
so now we have f(0)=8-12
there is no division
there is subtraction
8-12, which equals -4
f(0)=-4
You have 30 minutes to exercise at the gym. The Stairmaster burns 7 calories per minute, while the stationary bike burns 12 calories per minute. You want to burn 290 calories total using both machines. How much time should you spend on each machine?
Answers
Answer:
14 min on Stairmaster
16 min on Bike
Step-by-step explanation:
s = time on Stairmaster
b = time on bike
System of Equations:
s + b = 30
7s + 12b = 290
let 's' = 30-b
Substitution Method:
7(30-b) + 12b = 290
210 - 7b + 12b = 290
5b + 210 = 290
5b = 80
b = 16
s + 16 = 30
s = 14
The number 55 is multiplied by a 55 digit number that contains only ones. What is the sum of the digits of the product
Answers
Answer:
[tex]Sum = 64[/tex]
Step-by-step explanation:
Given
[tex]n = 55[/tex]
[tex]x \to 55\ digit[/tex] 1's
Required
The sum of the [tex]digits[/tex] of the [tex]product[/tex]
To do this, we start with smaller numbers
[tex]55*11 = 605[/tex] ---- 2 digits
[tex]55*111 = 6105[/tex] --- 3 digits
[tex]55*1111 = 61105[/tex] -- 4 digits
[tex]55*11111 = 611105[/tex] -- 5 digits
[tex]55*111111 = 6111105[/tex] --- 6 digits
Notice that as the 1's increase on the left-hand side, the 1's increase on the right-hand side
The difference between the count of both 1's is 2 1's
So, for n digits, we have: 6[n - 2, 1's]05
So, the sum is:
[tex]Sum = 6 + (n - 2) + 0 + 5[/tex]
For 55 digit, [tex]n = 55\\[/tex]
So, we have:
[tex]Sum = 6 + (55 - 2) + 0 + 5[/tex]
[tex]Sum = 6 + 53 + 0 + 5[/tex]
[tex]Sum = 64[/tex]

What are the measures of 1 and 2? 37.1 1 2 17.30 121.8°
Answers
Answer:
Option 2 : m∠1 = 67.4°, m∠2 = 104.5°
Step-by-step explanation:
Lets find the measure of angle 2 first:
180° - 17.3° - (180° - 121.8°) = Angle 2
↑
Angle of the straight line = 180°
The angle should be 180 - 121.8
Angle 2 = 104.5
At this point the only answer that works is the second option, but let's still work out Angle 1
Angle 1 :
Theory of opposite angles state that the opposite angles inside a triangle = the exterior angle
in this case:
Angle 1 + 37.1 = Angle 2
Since we know angle 2 = 104.5, lets solve
Lets say angle 1 = x
x + 37.1 = 104.5
x = 104.5 - 37.1
x = 67.4

Solution:-[tex]{\boxed{\mathcal{\red{Angle\: 1 \:=\: 67.4° \:}}}}[/tex]✅
[tex]{\boxed{\mathcal{\red{Angle\: 2\:=\:104.5° \:}}}}[/tex]✅
Step-by-step explanation:-We know that,
[tex]\sf\purple{Sum\:of\:angles\:on\:a\:straight\:line\:=\:180°}[/tex]
✒ ∠ x + 121.8° = 180°
✒ ∠ x = 180° - 121.8°
✒ ∠ x = 58.2°
Now,
[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]
➪ ∠ 2 + 17.3° + 58.2° = 180°
➪ ∠ 2 + 75.5° = 180°
➪ ∠ 2 = 180° - 75.5°
➪ ∠ 2 = 104.5°
[tex]\boxed{Therefore,\:the\:measure\:of\:∠\:2\:is\:104.5°.}[/tex]
Again,
[tex]\sf\blue{Sum\:of\:angles\:on\:a\:straight\:line\:=\:180°}[/tex]
➵ ∠ 2 + ∠ y = 180°
➵ 104.5° + ∠ y = 180°
➵ ∠ y = 180° - 104.5°
➵ ∠ y = 75.5°
Finally, we have
[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]
⇢ ∠ 1 + 75.5° + 37.1° = 180°
⇢ ∠ 1 + 112.6° = 180°
⇢ ∠ 1 = 180° - 112.6°
⇢ ∠ 1 = 67.4°
[tex]\boxed{Therefore,\:the\:measure\:of\:∠\:1\:is\:67.4°.}[/tex]

[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{(c-2)(c+2)}[/tex]
Multiply through by (c - 2)(c + 2) to clear the fractions
