157 degrees ... set 4x-5 = x+16 then solve, you should get x=7, plug in 7 for one of the equations and you'll get 23. subtract 23 from 180 and get 157. hope that helped :)
Your answer is D 6561 multiply each number 3 and your answer will be this
Answer:
volume of the solid is 3.180
Step-by-step explanation:
given data
line x + y = 2
parabola x2 + y = 4
to find out
the volume of the solid
solution
we draw a graph between line and parabola as show in fig given below attach
line cut at (-1,3) and (2,0)
so the length of diameter is ( 4 - x²) - (2 - x)
and radius of this semi circle will be ( 4 - x² - 2 + x ) /2
radius = (-x² + x + 2 ) /2
and r(x) will be = (-x² + x + 2 ) /2
and A(x) will be = π ( r(x)² ) /2
we will integrate from -1 to 2
=
=
= 81π / 20
volume of the solid is 3.180
Answer:
"Two complex solutions" is the answer.
The original price is $ 60
<em><u>Solution:</u></em>
Given information are:
Original price = ?
Percent of discount = 5 %
Sales price = $ 57
So, we have to find out the original price
Let "x" be the original price
Then, we can say,
Original price = sales price + discount percent of original price
x = 57 + 5 % of x

Thus original price is $ 60
