Since the sine and cosine functions are cofunctions, they are complementary. The format for this is that sinx=cos(90-x). This works for secant and cosecant and tangent and cotangent. So, sin25°=cos65°.
Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like 
. Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial,
, which equals 
. - Then, the outside terms,
. This equals 
. - Next, the inside terms,
. - Finally, the last terms,
, this equals 
.
Then, add all of the terms together 
. To get the standard form, combine like terms, this comes out to .
Distance between the 2 birds is 2.5 - (-2.5), or 5.0 (units).
Answer:
8 / 9 miles
Step-by-step explanation:
Given that:
Jason's distance = 1/3 mile
Jane's distance = 2/6 miles
Jude's distance = 2/9 miles
The total miles rowed down the river by all 3 :
(1/3 + 2/6 + 2/9) miles
The L. C. M of the denominator (3, 6, 9) = 18
(6 + 6 + 4) / 18
16 / 18 miles
8 / 9 miles
