So T(x) is another way to say y =
y = 19-(-3)
y = 19 + 3 When you subtract a negative, it is the same as adding a positive
y = 22
--or--
T(-3) = 22
Answer:
70ft
Step-by-step explanation:
a rectangle has the same length on two sides and the same height of two sides.
the height is 15 ft
the length is 20 ft.
20+25=35ft
35ftx2= 70ft.
the perimeter is 70ft.
(a) The integral is equal to the area of the triangle; it has height 20 and base 10, so the area is 20*10/2 = 100.
(b) The integral is equal to the area of the semicircle with radius 10. It's also under the horizontal axis, so the area is negative. The semicircle has area 
, so the integral is -50π.
(c) First compute
which is the area of the triangle on the right. It has height and base 5, so its area is 25/2.
Then split up the desired integral as
and plug in the integral values you know:
Hi there
To solve this question
0.03x+0.05 (6000-x)=220
Solve for x to know How much money was invested at 3%
First multiply the values
0.03x+0.05×6000-0.05x=220
0.03x+300-0.05x=220
Second calculate the difference and rearranging the values
0.03x-0.05x=220-300
-0.02x=-80
Divide both sides by-0.02 and divide the values
X=-0.02/-80
x=4000 invested at 3% this is the answer of your question
While the amount invested at 5% is
6000-4000=2000
Good luck!
