Answer:
114cm²
Step-by-step explanation:
Okay, so you can split this thingy up into a rectangle and another rectangle, so that's what we're going to do (see pic below)
So now we take off that 7 from the 13:
13 - 7 = 6
So now we find the area of that little area:
6 x 5 = 30
Now we do the other rectangle:
12 x 7 = 84
Now we add them together:
84 + 30 = 114
So the area of the shape is 114cm²
hope this helps:)
Answer: v = (12,16)
Step-by-step explanation:
if the midpoint is (10,9.5) and we know the coordinates of U as (8,3) the we could find the coordinates of V using the formula
solve for x and x will be the x coordinate.
8+x = 20
-8 -8
x = 12
3 + y = 19
-3 -3
y= 16
Answer: The change represents growth with 89% of growth rate.
Step-by-step explanation:
The exponential function is given by :-
... (i)
Where , A = initial value , b= multiplicative factor and x= time period
The given function : .
By comparing this to (i) , we get
b= 1.89 > 1 , thus it represent the growth.
Also,
i.e. Percentage rate of growth = 0.89 x 100 = 89%.
