Answer:

Arithmetic sequence

f(n) = 5n + 2

Step-by-step explanation:

f(1) = 7

f(2) = 7 + 5

f(3) = 7 + 5 + 5 = 7 + (2)(5)

f(n) = 7 + (n-1)(5)

f(n) = 7 + 5n - 5

f(n) = 5n + 2

Simplify and write the trig expression in terms of sin and cos

dsp73

We have:

$cot(-x)cos(-x)+sin(-x)=-\frac{1}{f(x)}$

Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:

$-sin(x)-cot(x)cos(x)=-\frac{1}{f(x)}$

We clear f(x):

$f(x)=\frac{1}{sin(x)+cot(x)cos(x)}=\frac{1}{sin(x)+\frac{cos(x)}{sin(x)}cos(x)}=\frac{1}{sin(x)+\frac{cos^2(x)}{sin(x)}}$

we simply what we can:

$f(x)=\frac{1}{\frac{sin^2(x)+cos^2(x)}{sin(x)}}=sin(x)$

Thus, the correct answer is;

$f(x)=sin(x)$

If i am dtiving 8 miles at 55 miles per hour how long willnit take

anyanavicka [17]

Answer:

It takes 0.145 hours

Step-by-step explanation:

Given:

Distance = 8 miles

Speed = 55 miles per hour

To Find:

Time taken = ?

Solution:

The time taken for an object to travel a particular distance with a average speed can be found by

$\text{Time Taken} = \frac{distance}{ speed}$

Now Substituting the given values , we get

$\text{Time Taken} = \frac{8}{55}$

$\text{Time Taken} = 0.145$

Time taken will be 0.145 hours
