Answer:
D. y = 2x² + 1
E. y = x²
Step-by-step explanation:
Linear function:
A linear function has the following format:
In which a is the slope and b is the y-intercept. A constant function is linear, as it is the special case in which a = 0.
In this question:
In options D and E, the highest exponent of x is 2, which means that they are not linear functions, and so these options are the answer.
The correct answer is [6,0] happy holidays :)
A 1/4 of an hour= 15 minutes=15*60=900 seconds
600 meters in 900 seconds means, her rate is 600/900= 2/3 meters in a second.
Hope this helps.
Answer:
x=8
Step-by-step explanation:
This isosceles triangle is composed of two right triangles with sides 8,
, and y
As we have two sides of a right triangle, we can find the third using the Pythagorean Theorem
As this is an isosceles triangle, these two right triangles are equal, this means that x=2y
Therefore, x=2(4)=8
I assume you're allowed to use sin and cos laws here, this is a trigonometry class, yes? Here we have an angle of a right triangle, and the side adjacent to it, and we need to find the hypotenuse. Since cos = adj/hyp, it's the proper one to use here:
Evaluate it with a calculator to get x = 12.04 units. Make sense?
