Answer:
C. <em>g(x)</em> = 1/4x²
Step-by-step explanation:
g(2) = 1/4 × (2)²
g(2) = 1/4 × 4
g(2) = 1
It matches the point (2,1) on the graph.
Hope this helps. :)
Answer:
1.52
Step-by-step explanation:
You can convert all the numbers into a fraction to solve the expression.
4/5 is equal to 80/100, and 0.35 is equal to 35/100. (37/100 is left as it is.)
80/100 + 35/100 + 37/100 = 152/100.
When simplified and converted into a decimal, the answer is 1.52.
The question is asking which formula will give the results
1, 9, 36, 100, 225, ...
for k values of
1, 2, 3, 4, 5, ...
You can try them out to see.
A) for k=2, gives 2*3/2 = 3 . . . not 9
B) for k=1, gives 2^3/3 = 8/3 . . . not 1
C) for k=2, gives (2^2*3^2)/4 = 9 . . . . looks promising
D) for k=1, gives 1*2^3/5 = 8/5 . . . not 1
Selection C is the only viable choice. (And the correct one.)
To solve this, we'll use the trigonometric function called cosine.
The cosine of an angle -in a right triangle-, is equal to the side adjacent to the angle over the hypotenuse of the triangle.
Given the angle 41, its adjacent side is
and the hypotenuse is 55, so:
We solve for
:
The answer is 41.51.
