Answer:
the best estimate is 361.4 dude
Step-by-step explanation:
Answer: 74
Step-by-step explanation:
Substitute x=6 into the expression
(x+4) . 2^3 -6
Add the numbers
(6+4) . 2^3- 6
10 x 2^3 -6
Evaluate the power
10 x 2^3 -6
10 x 8-6
Multiply the numbers
10 x 8-6
80-6
Subtract the numbers
80-6
74
I would say 16 times the square root of 2, but I am not positive.
Answer:
no solution
Step-by-step explanation:
6r + (s/2) = 19 -> eq(1)
2r + (s/6) = 8
There is no solution.
Answer:
x = y = 4
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = 
, then
cos45° = 
= 
( multiply both sides by 8 )
8 × cos45° = x , then
x = 8 × = 4
The third angle in the triangle = 45° ( sum of angles in triangle )
Then the triangle is isosceles with congruent legs, thus
x = y = 4
