Answer:
A
(1,5),(2,6),(4,5)
Step-by-step explanation:
Think of the answer choice in a table
x | y
1 | 5
2 | 6
4 | 5
exactly one input (x) has one output (y)
in a function likw this you have to make sure that the x is going to one y.
if not than it is not a function.
(1,2),(1,5)(3,9)
see the one in this orderd pair goes to 2 and 5 so in is not a function
To calculate what is asked we use the formula for radioactive decay. It is expressed as follows:
An = Ao (e^(-kt))
We calculate as follows:
An = Ao (e^(-kt))
74 = 100 (e^(-k(10)))
k = 0.0301
1/2 = (e^(-0.0301t))
t = 23 hours
Hope this answers the question.
Answer:
y=4
Step-by-step explanation:
<h3>The triangle is divided further into 2 right triangles. So ignore the left one.</h3><h3>We know the angle of elevation is 30° and the hypotenuse is 8.</h3><h3>Looking at SOH CAH TOA we use the sine ratio in trigonometry because we have to find the side opposite to the angle given and we know the hypotenuse. </h3><h3>It is: sin 30 = y/8</h3><h3>y= 8 sin 30</h3><h3>y=4</h3>
The correct answer is 64/6.
Answer:
D
Step-by-step explanation:
The slope is 1/2, which will be a constant, making it a linear function.
