True [87]

Answer:

Step-by-step explanation:

The question is:

What percent of time did Nik spend with clients on Thursday?

a. 10%

b. 70%

c. 30 %

d. 80%

Solution:

c means client meetings and o means other work.

The hours are shown in the table.

We want % of time on Thursday that he spent on clients.

In Thursday:

7c and 3o

Means 7 hours with clients and 3 hours with office work.

Total time spent = 7 + 3 = 10 hours

Client time spent = 7 hours

% time spent with clients on Thursday: 7/10 = 0.7 * 100 = 70%

Answer choice B is right.

BRAINLIEST PLEASE HELP ASAP!!!!

Mashcka [7]

For this case we have that by definition of power properties it is fulfilled that:

$(a ^ n) ^ m = a ^ {n * m}$

We must rewrite the following function:

$f (x) = 7 (\frac {1} {2})^{3x}}$

Using the mentioned property we have:

$f (x) = 7 ((\frac {1} {2}) ^ 3) ^ x$

Solving the operation within the parenthesis we have:

$f (x) = 7 (\frac {1 ^ 3} {2 ^ 3}) ^{ x}\\f (x) = 7 (\frac {1} {8})^{x}$

Thus, the correct option is option B

Identify the sine function with the given attributes.

Thepotemich [5.8K]

Answer:

Last option

$f(t)=sin(\pi(t -3)) + 4$

Step-by-step explanation:

The general sine function has the following form

$y = Asin(bt-\phi) + k$

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.

$\frac{2\pi}{b}$ is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

$\phi$ phase shift

We know that:

amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Thus:

$A =1$

$\frac{2\pi}{b}=2$

$b=\pi$

$\phi=3$

$k=4$

Then the function is:

$f(t)=sin(\pi(t -3)) + 4$

The answer is last option
