Answer:
64.025°F
I think I did it right
Step-by-step explanation:
65=100%
65/100=0.65
0.65=1%
3%=1.95
4.5%=2.925
65+1.95=66.95
66.95-2.925=64.025
Y-25 = 8x+25-25
-25/8 = 8x/8
x = -25/8 or -3.125
Answer:
7,5
Step-by-step explanation:
Answer:
19 square units
Step-by-step explanation:
There are a LOT of different ways to solve this problem, most of which involve breaking up the shape into smaller shapes. For me, it’s easier to draw a rectangle around the figure, find that area, and then subtract the four areas not in the figure.
Rectangle: would be from -3 to 3 (6) and -2 to 4 (6). 6x6=36
The four missing triangles:
AB = 1/2(3)(2)=3
BC = 1/2(2)(4)=4
CD = 1/2(2)(4)=4
DA = 1/2(4)(3)=6
6+4+4+3=17
36-17=19
Part A: After 9 days the radius of algae was approximately 12.81 mm. The reasonable domain to point is (0,9).
Part B: The 9 on the y-intercept represents the amount of algae the experiment started with.
Part C: (12.81-10.12)/7=0.38
