Answer:

k = 2

Step-by-step explanation:

f(x) and g(x) = f(x) + k

G(x) is the function f(x) moved up k units

G(x) is moved up 2 units so k is 2

A team of seven workers started a job, which can be done in 11 days. On the morning of the fourth day, several people left the t

Lapatulllka [165]

Answer:

3 people left

Step-by-step explanation:

The job can be completed by 7 people in 11 days
The job is equivalent of 7*11 = 77 people*days

After 3 days, job left:

(11 - 3)*7 = 56 people*days

This was completed by 7 - x people as x people left

Time needed was 14 days, we have new equation:

14(7 - x) = 56
7 - x = 4
x = 7 - 4
x = 3

As we found, 3 people left

Nick decided to take 2/5 of the money in his bank account and donate it to a local charity. If nick donated $70 to a local chari

S_A_V [24]

Answer:

The total amount = $175

Step-by-step explanation:

Let the total amount in his bank account = x

Nick decided to take 2/5 of the money in his bank account and donate it to a local charity

So, he donates with $\frac{2}{5} x$

If nick donated $70 to a local charity

so, $\frac{2}{5} x = 70$

solve for x

∴ x = 5*70/2 = 350/2 = $175

So, The total amount = $175

What is the value of 324 + 435 + 546 when written in base 7?

Arada [10]

The sum of 324, 435, and 546 is 1305. If this number were to be expressed by the base of 7, we would need to figure out what value of exponent would satisfy the requirement. This can be done by setting up an equation where 7 to the power of x must equal 1305. Using logarithms, one can solve for x and find it to be 3.6866853. Thus the sum of the aforementioned numbers, expressed in by the base of 7, is 7^3.6866853.
