On the graph of f(x)=cos x and the interval [0,2π), for what value of x does f(x) achieve a minimum?
Mariulka [41]

Answer:

cos(\pi)=-1

Step-by-step explanation:

f(x)=cos (x)

State that the values where cos x is minimum:

x=\pi +2\pi n, n\in \mathbb{Z}

cos(0)=1\\

$cos\left(\frac{\pi}{4} \right)=\frac{\sqrt{2} }{2} $

$cos\left(\frac{\pi}{2} \right)=0 $

cos(\pi)=-1

$cos\left(\frac{3\pi}{2} \right)=0 $

How would you write 4n + 3 as a verbal expression
Tatiana [17]
<h3>4 times a number increased by 3.</h3>

When we have a number that appears

right before a variable, it means multiplication.

So 4n means the same thing as 4 times a number.

Remember, n is a variable which is just a

letter that represents any number.

Since we are adding 3 to 4n, we can say

4 times a number increased by 3.

So 4n + 3 can be written as 4 times a number increased by 3.

you deposit 200 into an account that pays 7% interest compounded quarterly. how much will you have in 5 years
scoray [572]
First, convert R percent to r a decimal
r = R/100
r = 7%/100
r = 0.07 per year,

Then, solve our equation for A
A = P(1 + r/n)nt
A = 200.00(1 + 0.005833333/12)(12)(5)
A = $ 283.53

Summary:
The total amount accrued, principal plus interest,
from compound interest on an original principal of
$ 200.00 at a rate of 7% per year
compounded 12 times per year
over 5 years is $ 283.53.
