The answer is 58 .
5x5=25
2x2x2x2x2=32
25+32=57
57+1=58
Answer:
Step-by-step explanation:
6) taking 45 degrees as the reference angle,
the adjacent side is √6
The opposite side is x
The hypotenuse is y
Therefore, we would apply trigonometric ratio.
Tan # = opposite side / adjacent side
Tan 45 = x/√6
1 = x/√6
x = 1 × √6 = √6
Cos # = adjacent side/hypotenuse
Cos 45 = √6/y
Cos 45 expressed in surd form is √2/2. Therefore,
√2/2 = √6/y
y √2 = 2√6
y = (2√6)/√2
Answer: The student's estimate is off by 12%
Answers to the entire test:
Step-by-step explanation:
1. C. a<b
2.A. x >_0
3. A. The product between 3 and a number is greater than 9
4. B. The difference of 16 and the product of 5 and a number is no less than 1
5.B. 6(x-4)<_20
2x - 11 >_ 5
To solve for x, we need to get 2x by itself and then simplify.
Add 11 to both sides.
2x >_ 16
Divide both sides by 2 to get x.
x >_ 8 is your solution.
I hope this helps!
