Answer:
y = -2
Step-by-step explanation:
y + 4 = 2
y = 2 - 4
y = -2
Here’s the correct answer and how I got the answer :)
Answer:
A = 693
Step-by-step explanation:
The shape presented is a parallelogram, and the formula for this is:
A = bh
The "b," is the base (21) and the "h," is the height (33), so plug this in:
A = (21)(33)
A = 693
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
#4 is actually f(x) + 18. #5 is f(x) + 201, #5 is f(x) + 316.
