Answer:
Y=(9/4)x+9
Step-by-step explanation:
You can use the slope formula to find the slope (look up on google) for m and then the y intercept is given so the is your b.
Answer:
4
Step-by-step explanation:
25+25=50
50*2=100
100/25=4
See the picture attached to better understand the problem
we know that
in the right triangle ABC
cos A=AC/AB
cos A=1/3
so
1/3=AC/AB----->AB=3*AC-----> square----> AB²=9*AC²----> equation 1
applying the Pythagoras Theorem
BC²+AC²=AB²-----> 2²+AC²=AB²---> 4+AC²=AB²----> equation 2
substitute equation 1 in equation 2
4+AC²=9*AC²----> 8*AC²=4----> AC²=1/2----> AC=√2/2
so
AB²=9*AC²----> AB²=9*(√2/2)²----> AB=(3√2)/2
the answer isthe hypotenuse is (3√2)/2
Always we can use logic on this p q is true and q is. true which means p is always true
