Cotx = cosx/sinx
cscx = 1/sinx
If we plug these into your equation we get:
(cosx/sinx)/(1/sinx) - 1
Dividing by a number is the same as multiplying by its reciprocal so it can be rewritten as:
(cosx/sinx)(sinx) - 1
The two sinx's cancel each other out so we end up with cosx - 1
The verbal expression for 7 to the third power is 343
Using it's concept, it is found that the relative frequency probability of rolling an even number based on this experiment is
.
A relative frequency is the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- 50 dices are thrown, hence
. - 22 resulted in an even number, hence

The <u>relative frequency</u> is given by:

The second store price is cheaper beacuse 16% of 573 gives off $91.68 and when u do that u get $481.32 so 458.40 is cheaper.
Answer:
this is correct
Step-by-step explanation:
f continous in x=30 means that it should be the same value for 1.25 x 30 and 1.10 x 30 + k so k =4.5
