The square of 60 is closest to -8 and 8 since 7x7=49 which is 11 away while 8x8=64 only 4 away.
What you have is slope intercept form(best for graphing)
Ax+By=C and A must be positive
-1x+y = -8
so now A is negative so we multiply by another negative
1x-y = 8
The rest of the numbers can be negative and that is standard form.
Answer:
It will take 8 minutes
Step-by-step explanation:
3 hours 28 minutes = how many minutes
3 hours * 60 minute/hour = 180 minutes
3 hours 28 minutes =180 +28 = 208 minutes
We can use proportions to solve
26 miles 1 mile
--------------- = --------------
208 minutes x minutes
Using cross products
26 * x = 208 *1
26x = 208
Divide by 26
26x/26 = 208/26
x = 8
It will take 8 minutes
Answer:
π
Step-by-step explanation:
The integral decomposes into the sum ...

The first term of this sum is the integral of an odd function, so is zero. The second term of this sum is 1/2 the area under a semicircle of radius 2, so is ...
A = (1/2)(1/2)π·2² = π
The value of the integral is π.
