Answer:
option (4) is correct.
Coefficient in the given expression is 6 and
Step-by-step explanation:
Consider the given expression
We have to determine the coefficient in this expression,
Coefficient is a constant term that is placed before variable term in an expression. example 4x , here 4 is coefficient.
In the given expression , we have two variables a and b,
So coefficient of a is 6 and coefficient of b is
Thus, option (4) is correct.
Coefficient in the given expression is 6 and
Answer: N(t) = (2^t)*1500
Step-by-step explanation:
Let's define the hour "zero" as the initial population.
So if N(t) is the number of bacteria after t hours, then:
N(0) = 1500.
Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1
N(1) = 2*1500 = 3000
after two hours, at t = 2.
N(2) = 2*(2*1500) = (2^2)*1500
After three hours, at t = 3
N(3) = 2*(2^2)*1500 = (2^3)*1500
So we already can see the pattern, the number of bacteria after t hours will be:
N(t) = (2^t)*1500
Answer:
C
Step-by-step explanation:
A pyramid is the 3-D shape of a triangle. If you cut the pyramid, you will get a triangle.
Answer:
top one is 48 cm, bottom one is 17.5in.
Step-by-step explanation:
From what I understand, these shapes are increasing in size, so they will increase at a certain number. Our top one is rotated, but the 12cm is equivalent to the 3cm from the previous rectangle, thus making it greater by 4 times. To find x, we multiply 12cm by 4 to get 48cm. Same concept for the shapes on the bottom. Our 56in is equivalent to 8in, making it 7 times larger. Now, we multiply 2.5 by 7 to get 17.5in.
