Answer:
B. 29.7
Step-by-step explanation:
All you have to do is find the area of the half circle (r² × 3.14 × ½) and subtract that from the initial area of the rectangle ( 9×4 ) After doing that it gives you 29.7ft².
Using the concept of supplementary angles, it is found that the measure of angle B is of 135º.
--------------------------------
- If two angles are supplementary, the<u> sum of their measures is of 180º</u>.
- A and B are supplementary, thus:
- The measure of angle A is 1/3 of the measure of angle B, thus:
Replacing in the equation for the sum:
The measure of angle B is of 135º.

Answer:
f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2
Step-by-step explanation:
For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.
For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.

Answer:
Step-by-step explanation:
Given that a bacteria culture initially contains 100 cells and grows at a rate proportional to its size.
i.e. P' = kP where k = constant of proportionality
We separate variables and solve this Differential equation.
When t =0 P(0) = A = 100
So equatin is
to find k
When t=1, P =590
So
