A population of bacteria contains 150 bacteria in generation 1 and triples in
population every generation. This sequence represents the number of
bacteria for the first few generations:
150, 450,1350, ...
What is the explicit formula for the number of bacteria in generation n?
Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
Step-by-step explanation:
It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.
The first generation has 150 representatives, so b1=150
The formula of geometrical sequence is bn=b1*r^(n-1)
(in our case bn is a quantity of bacteria in generation n)
so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)

Answer: 1/4n-12=6
1n/4-12=6
n=72
Step-by-step explanation:
Answer:
72
Step-by-step explanation:
let the number be n , then
[tex]\frac{1}{4}[/tex] n - 12 = 6 ( multiply through by 4 to eliminate the fraction )
n - 48 = 24 ( add 48 to both sides )
n = 72
What is 10% less than 220?
Answer:
198
Step-by-step explanation:
10% less of 220
=> 220 - 10% of 220
=> 220 - (10/100 × 220)
=> 220 - 22
=> 198

What is the slope of What the slope of (6, -1) over (7, 3)
Answer:
4
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3 - -1)/( 7-6)
= ( 3+1)/( 7-6)
= 4/1

You eat 3/10 of a coconut. Your friend eats 1/5 of the coconut. What fraction of the coconut do you and your friend eat? Write your answer as a fraction in simplest form
Answer:
1/2 of the coconut.
Step-by-step explanation:
1/5 is equal to 2/10, so we can add these two fractions as 3/10 + 2/10, or 5/10. Simplifying this gets us 1/2, so you and your friend eat, in total, half of the coconut.

What is the slope of –3x + 5y = 10? A. m = B. m = 5 C. m = – D. m = –3
Answer:
The slope is 3/5
Step-by-step explanation:
–3x + 5y = 10
Rewrite the equation in slope intercept form y = mx+b where m is the slope and b is the y intercept
Add 3x to each side
5y = 3x+10
Divide by 5
y = 3/5 x + 10/2
The slope is 3/5

help me, please everyone;-;
Step-by-step explanation:
Using the power law of indices:
When two numbers with the same base multiply,add the exponents that is
[tex] {a}^{2} \times {a}^{3} = {a}^{2 + 3} = {a}^{5} [/tex]
Again,when two numbers with the same base divide, subtract the exponents,that is
[tex] {a}^{2} \div {a}^{4 } = {a}^{2 - 4} = {a}^{ - 2} [/tex]
There are way too many examples that is why I have elaborated the two laws for your perusal.
So for instance:
1.
[tex] {2}^{2} \times {2}^{5} = {2}^{7} [/tex]

Can someone please explain how to find the difference -7 - (-8)
Answer:
1
Step-by-step explanation:
In the equation -7 - (-8), there are two 'minus' signs; we can convert two minus signs into a plus sign according to the 'minus minus equals plus' rule, that would make the equation (-7) + 8 for which the answer is +1.
Answer:
1
Step-by-step explanation:
-7-(-8)
First you should solve the brackets.Remeber (-) minus into (-) equal (+)therefore;
-7-(-8)= -7+8
when there is a minus and a plus you should minus the two numbers and put the largest value sign.therefore;
-7+8= 1
Hope you understand.If you have any problem just ask me I will solve it.

The formula for the perimeter of a rectangle is P = 2l + 2w. Solve the formula for l
in terms of P and w.
Answer:
P/2 -w = l
Step-by-step explanation:
P = 2l + 2w
Subtract 2w from each side
P-2w = 2l + 2w-2w
P -2w = 2l
Divide each side by 2
(P-2w)/2 = 2l/2
P/2 -w = l
