From the identity,
sin^2(x)+cos^2(x)=1
then
cos(x)=sqrt(1-sin^2(x))
where sin(x) is given as 0.42.
Note that the above answer applies to 0<x<90 degrees
5
2 = 32
Exponents are like a simplified or easier version of multiplying
2*2*2*2*2
People use exponents in real life. For an example, they use it for finding cubic feet ,square feet, or area of something or an object.
Sorry if I am bad at explaining this or if I confused you
10%of30=3
3x4=12
A. 40%of 30=12 senior class members.
B. 60% of the class were not senior class members
-3(x+(3))^2-4 is the answer
-8/5
Rise over run aka how many it goes up/down over how many it goes across
