Start with the solution
x=-25
use the reverse of what they asked
they wanted division and addition
we use multiplication and subtract
ok
x=-25
we can use subtraction and multiplication in any order
minus 10 from both sides
x-10=-35
multiply both sides by 4
4(x-10)=-140
4x-40=-140 is a possible equation
Answer:
1.25(-xsquare - 8x + 16)
Step-by-step explanation:
pls give me brainliest
I'm not sure but I think so
Since you mentioned calculus, perhaps you're supposed to find the area by integration.
The square is circumscribed by a circle of radius 6, so its diagonal (equal to the diameter) has length 12. The lengths of a square's side and its diagonal occur in a ratio of 1 to sqrt(2), so the square has side length 6sqrt(2). This means its sides occur on the lines 
and 
.
Let 
be the region bounded by the line 
and the circle 
(the rightmost blue region). The right side of the circle can be expressed in terms of 
as a function of 
:
Then the area of this circular segment is
Substitute 
, so that 
Then the area of the entire blue region is 4 times this, a total of 
.
Alternatively, you can compute the area of in polar coordinates. The line becomes 
, while the circle is given by 
. The two curves intersect at 
, so that
so again the total area would be 
.
Or you can omit using calculus altogether and rely on some basic geometric facts. The region is a circular segment subtended by a central angle of 
radians. Then its area is
so the total area is, once again, .
An even simpler way is to subtract the area of the square from the area of the circle.
Do you need to find what t is? If so, do 300 divided by 60 to get the t isolated. which is, 5.
you can check by doing 60*5 which is 300
Answer:
100.48
Step-by-step explanation:
Get the Radius which is 8 then multiply (8)(8) and then get 64, finally you need to do 64*3.14 to get the final answer of 200.96. Then you need to divide that by two which would give you the final answer of 100.48
