Answer:
r = - 9
Step-by-step explanation:
Given
4r + 10 = - 26 ( subtract 10 from both sides )
4r = - 36 ( divide both sides by 4 )
r = - 9
Answer:
Step-by-step explanation:
The three consecutive integers are
(n+2), (n+3), (n+4).
(n+2)+(n+3)+(n+4) = 3n+9
Answer:
Step-by-step explanation:
3 and 2/5
(aka A)
Answer:
-3
Step-by-step explanation:
firstly, -3/12 is not in the simpliest form so we have to simplified it:
-3/12 / 3 = -1/4, now we got:
= (-6*(-1/4)*-4*5) / 10
The upper part of the equation: (-6*(-1/4)*-4*5) can be simplified as:
((-6*-1*-4*5) / 4) / 10
= (-120/4)/10
= -30 / 10
= -3
Hope this help you :3
Answer:
Step-by-step explanation:
Recall the following Pythagorean Identity:
Let's solve the x equation for cos(t) and the y equation for sin(t).
After the solve we will plug into our above identity.
x=5cos(t)
Divide both sides by 5:
(x/5)=cos(t)
y=5sin(t)
Divide both sides by 5:
(y/5)=sin(t)
Now we are ready to plug into the identity:
Multiply both sides by 5^2:
This is a circle with center (0,0) and radius 5.
All I did to get that was compare our rectangular equation we found to
where (h,k) is the center and r is the radius of a circle.
