Answer:
263.9 cm^3 to nearest tenth.
Step-by-step explanation:
V = 1/3 π r^2 h
= 1/3 π 6^2 7
= 12 * 7 π
= 84π
= 263.8938
Answer:
a). true
b). true
Step-by-step explanation:
a).
Given : If a = 5, then ac = 5c
Let c be any constant.
a = 5 (given)
Therefore, ac = 5c
Here a is given a constant value (5), also let assume c to be a constant. So when we multiply each term we will get a constant value of 5c. The ratio does not change.
Hence proved.
b).
Given : If ac = 5c, then a = 5
Let c be any constant
It is given, a = 5
Therefore, ac = 5c
Here the product of two terms is given as 5c, where c is assume to be a constant. Then as a product rule, the value of a will be 5. The ratio will not change.
Hence proved.
That would be 6x. Ignore the x's, -3 + 9 = 6.
Answer:
The population size after eight days is about 265
Step-by-step explanation:
This is an example of an exponential growth model. A quantity <em>y</em> that grows or decays at a rate proportional to its size fits in an equation of the form

where k is a positive constant. Its solutions have the form
,
where
is the initial value of y.
The population size can be calculated by using the below formula:
where
is the population on day zero.
Let t be the time in days,
We know from the information given that:
- k = 0.4964 per member per day and
- The day zero (t = 0) the population size is 5 (P(0) = 5)
To find the population size after eight days
Substitute P(0) = 5, k=0.4964 in 
Then

Now we calculate P(t) when t = 8 days

Therefore the population size after eight days is about 265
