The number ab², where a and b are prime numbers, has 6 divisors.

<h3>How many divisors are for the given expression?</h3>

Remember that any number can be written as a product of primes, for example, 15 can be written as:

15 = 3*5

Where 3 and 5 are primes.

Such that the divisors of 15 are the factors made with the primes on the right side.

So for the number:

N = a*b^2 = a*b*b

The divisors are:

a, b, a*b, b*b

And trivially, itself and 1, so there are a total of 6 divisors.

Dan buys a car for £2100.

SVETLANKA909090 [29]

Answer:

£1837.5

Step-by-step explanation:

Given data

Cost of car P= £2100.

Rate r= 2.2%

Time t= 6 years

Now we want to find the worth after 6 years, let us apply the compound interest expression but this time for depreciation

A= P(1-r)^t

Substitute

A= 2100(1-0.022)^6

A= 2100*(0.978)^6

A= 2100*0.875

A= £1837.5

Hence the amount of the car after 6 years is £1837.5

What's the answer to this question and how do I solve it?

Answer:

80 gummy bears are in 4 servings.

Step-by-step explanation:

2 servings=40 gummy bears

3 servings=60 gummy bears

40+20=60

Add 20 gummy bears for every serving.

5 servings=100 gummy bears

100-20=80 gummy bears are in 4 servings

OR you can also do:

40÷2=20 gummy bears are in each serving

So, 4x20=80 gummy bears are in 4 servings

Yakvenalex [24]

Given:

$\begin{gathered} f(s)=e^s-4 \\ \\ g(s)=\frac{1}{2}e^s-4 \end{gathered}$

From the function above, there was a horizonal stretch.

using the transformation rule:

$(x,y)\Longrightarrow(\frac{x}{b},y)$

Therefore, we can say that there is a horizontal shift of the graph to the right.

ANSWER:

B. The graph of the function g(s) is a horizontal shift of the graph of the function to the right.
