Answer:
First box +2
Second box -5
Step-by-step explanation:
Just an Example,
If f(x) = 2x + 1 and we need f(2) we would replace the x in the function with the number 2 because 2 is the domain of the function , so f(2) would become,
f(2) = 2(2) + 1
f(2) = 4 + 1 = 5
Now the question is what is f(g(x)) in this case the domain of the function is g(x). In simpler words we replace x with the function g(x) so here goes,
so,
f(g(x)) = 2x - 5
Answer:
10%
Step-by-step explanation:
Marked price of the shirt = Rs 1000
Sale price = Rs 900
Decease = (1000 - 900) Rs
= Rs 100
% decrease = decrease /marked price x 100%
That’s 100/1000 x 100%
0.1 x 100
10%
Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2
Answer:
2
Step-by-step explanation:
Answer:
13.5 inches
Step-by-step explanation:
Perimeter of the paper square = 18inches
Perimeter of a square = 4s
4s = 18 inches
s = 18/4 = 4.5 inches
Therefore, each side of the square = 4.5 inches.
When the square is cut into 2 rectangles,
The perimeter of one of the rectangles is 10 inches.
Perimeter of the second rectangle = 2L + 2W
Let the length of the rectangle (L) = one side of the square = 4.5 inches
Width of the Rectangle = Length of the square/2 = 4.5 inches/ 2 = 2.25
Perimeter of the second rectangle = 2(4.5) + 2(2.25)
= 9 + 4.5
= 13.5 inches
