Answer:

B. 1

Step-by-step explanation:

Your answer for A is correct.

The time it take for the sub to hit the water will be the time between when the submarine started to get lowered and when its distance from the water was zero.

The sub started to get lowered at x = 0.

Now we need to solve for the smallest positive zero of the function.

This function factors to (x - 1)(x - 7)

From this we can tell that the submarine is a water level for time x = 1 and x = 7.

The smallest of these is 1, so that is when the submarine first hit the water and 7 is when it came back out.

The sub started getting lowered at x = 0 and hit the water at x = 1 and because x is in seconds, it took 1 second for the sub to hit the water.

A store is hoping an advertising campaign will increase their number of customers by 30%. They currently have about 80 customers
leonid [27]

Answer:

There will be 104 customers a day, after advertising campaign

Step-by-step explanation:

Current number of customers in a day in shop = 80

After advertising campaign, the customers will increase = 30%

So, new customers will be:

We can find new customers by adding new 30% customers to the current 80 customers.

First find 30% of 80

30\% \  of \ 30\\=\frac{30}{100}*80\\=24

Now, add 24 to current 80 customers.

Number of customers = 80+24 = 104

So, there will be 104 customers a day, after advertising campaign

Answer:

  • y = 20
  • 4^8
  • x = 0

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  a^0 = 1 . . . . for a ≠ 0

__

And, it is convenient to know the cubes of small integers:

  1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125

  6³ = 216; 7³ = 343; 8³ = 512; 9³ = 729; 10³ = 1000

__

1) p^3 × p^5 = p^-12 × p^y

Equating exponents:

  3 + 5 = -12 + y

  20 = y . . . . . . . . . . . add 12

__

2) 64 × 4^5 = 4^3 × 4^5 = 4^(3+5) = 4^8

__

3) 10^x = 1 = 10^0

  x = 0
