20 times 4 will get to 80
Answer:

Step-by-step explanation:
we know that
The area of the figure is equal to the area of an isosceles triangle (has two equal sides) plus the area of a rectangle
step 1
Find the area of the triangle
The area of the triangle is equal to

we have

To find out the height of the triangle Apply the Pythagorean Theorem

solve for h




<em>Find the area of triangle</em>


step 2
Find the area of rectangle
The area of rectangle is equal to

we have

substitute

step 3
Find the area of the figure
Adds the areas

-2p<span><20-4
-2p</span><span><16
thus,
p</span><span>>-8</span>
At day 0 the height of the plant = 12 cm
Calculate how many days to get to 16.13 cm:-
16.13 = 12(1.03)^n
1.03^n = 16.13 / 12 = 1.34417
n = ln 1.34417 / ln 1.03 = 10 days
I would think that a reasnable domain would be 0 =< n <= 100
Answer:
The initial weight of the bar soap is 123g
Step-by-step explanation:
No options but the question can still be solved.
Given

Required
What does the y intercept mean
Start by calculating the y intercept (i.e. when x = 0)
The equation becomes



This means that the initial weight of the bar soap is 123g
