2b=12-18
2b=-6
b=-3
That is the answer
Answer:you get two answers. y+6=-7/4(x+5) or y-1=-7/4(x+5)
Step-by-step explanation:
By the way the 7/4 is negative if you could not tell. You get this answer by finding the slope which is 1- -6/-5- -1 and get -7/4. Then you plug it into the formula y-y1=slope(x-x1). When you plug it in you should get that answer.
To complete this problem, we are going to need to use the Pythagorean theorem.
1.find x. as mentioned earlier, we are going to use the Pythagorean theorum (a²+b²=c²). substitute a b and c for the values on the triangle then solve:
x²+3²=5² substitute
x²+9=25
x²=25-9 subtract
x²=14
x≈3.7 solve to the nearest tenth
2. x is about 3.7km. now we need to find y. to do so, we are going to do the same steps that we did to find x:
y²+3²=7²
y²+9=49
y²=49-9
y²=40
y≈6.3
3. now we know all 3 horizontal side lengths so all we need to do to find the total horizontal distance is add the 3 together:
3.7+3+6.3
13
4. after doing all that math we finally got the answer: The plane's total horizontal distance is about 13km.
I hope this was helpful! :)
The answer is 4 and 6 (I mentioned the Z rule in my previous answer, I did not know the english term for it looks like it is 'alternate interior')
Answer:
Step-by-step explanation:
The formula for circumference is given by . Setting this equal to the circumference in the problem, we can find the radius of the sphere:
Now we can use the formula for the surface area of a sphere:
Surface area of a sphere:
Using :
