The equation of the circle whose center is (0, 0) and whose radius 5 is x² + y² = 25.
What is an equation of a circle?A circle can be characterized by its center's location and its radius's length.
Let the center of the considered circle be at (h,k) coordinate.
Let the radius of the circle be 'r' units.
Then, the equation of that circle would be:
(x-a)²+(y-b)² = r²
Where (a, b) is the centre and 'r' is the radius
We have a circle with centre (0, 0) and radius of 5.
Now, Substituting these value into the equation form, we have
(x-0)²+(y-0)² = 5²
x² + y² = 25
Hence, the equation of the circle whose center is (0, 0) and whose radius 5 is x² + y² = 25.

Answer:
[tex]h = \frac{2A}{b + c}[/tex]
Step-by-step explanation:
Given
[tex]A = \frac{1}{2}(b + c)h[/tex]

Solve for h
We have:
[tex]A = \frac{1}{2}(b + c)h[/tex]
Multiply sides by 2

If a moped goes 30 miles per hour, how many hours will it take to travel
217.5 miles?
Answer:
217.5
Step-by-step explanation:
There are two ways to do this problem, first dividing to find the missing value. It will look like this:
217.5 ÷ 30 = 7.25
Or, using random numbers and multiplying it by 30, which is like this:
30 × 10 = 300
30 × 4 = 120
30 × 7 = 210
30 × 7.1 = 213
30 × 7.25 = 217.5

I converting frm base ten to base 2 what do u do?
Answer:
See explanation for example.
Step-by-step explanation:
Say we want to convert 567 to binary aka base 2.
Look for highest power of 2 that will go into 567.
2^x will get us close to 567.
You could solve 2^x=567 in take the whole part of the number.
x=log_2 (567)=approximately 9.1
Of course you don't have to use logarithms here. You could have just found 2^0,2^1,...,2^9. You could have kept increasing the power on 2 until you exceeded the number,567, you wanted and use the power of 2 just before that number, 567.
2^9=512
So what's left 567-512=55
2^6=64 so that's too much, so 2^5=32 is what we will go with next.
55-32=23
2^4=16 and now 23-16=7 is left
2^2=4 so 7-4=3 is left
2^1=2 so 3-2=1 is left
2^0=1 and there is nothing left over
So we had 1, 2^9
No 2^8,2^7,2^6
We had 1, 2^5
We had 1, 2^4
We had no 2^3
We had 1, 2^2
We had 1, 2^1
We had 1, 2^0
The binary aka base 2 representation of 567 is 1000110111.

Answer:
x = 1
Step-by-step explanation:
6x - 9 = 2x - 5
Move variables to one side
6x - 9 = 2x - 5
-2x -2x
4x - 9 = - 5
Isolate variable
4x - 9 = - 5
+ 9 +9
4x = 4
4x/4 = 4/4
x = 1

Find the measure of the indicated angle to the nearest degree
Answer:
57°
Step-by-step explanation:
,using soh cah TOA the sides in the right angle concerning us are the adjacent and hypotenuse
where 14 is the adjacent and 26 is the hypotenuse
...therefore cos(x) ,that is,the unknown angle
cos(x)=14/26
cos(x)=0.5385
cos¹(0.5385)=57.42

does anybody know the answer?
A ramp is used to load a snowmobile onto the back of a pickup truck. The truck bed is 1.3m above the ground. For safety, the angle of the ramp should be less than 40°. What is the shortest possible length of the ramp to the nearest centimetre? Explain why.
Answer:
2.02 m
or 2 m 2 cm
Step-by-step explanation:
Imagine a triangle containing the 40° angle and that this angle is at the left. Then the height of the truck bed is 1.3 m and the "shortest possible length of the ramp" is the hypotenuse of this triangle. We need to find the length of this ramp, that is, the length of the hypotenuse.
The sine function relates this 40° angle and the 1.3 m height of the truck bed:
sin 40° = opp / hyp = 1.3 m / hyp
which can be solved for 'hyp' as follows:
1.3 m
hyp = ----------------- = (1.3 m) / 0.6428)
sin 40°
1.3 m
Thus, the length of the ramp must be less than -------------- or 2.02 m
0.6428
where this last result is to the nearest cm.
If the ramp is shorter the angle of the ramp will be smaller and the ramp angle considered safer.
