Part A: What is the y-intercept of the function, and what does this tell you about the truck?
The intersection of a function with the y-axis occurs when we evaluate the function for x = 0.
For this case we have:
f (0) = 330 miles
Therefore, the intersection with the y-axis is 330 miles.
It means that the truck is 330 miles from its destination.
Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 4 hours, and tell what the average rate represents.
Since the function is linear, the average exchange rate is:
m = (y2-y1) / (x2-x1)
Substituting values:
m = (275-330) / (1-0)
m = -55
It represents that the truck approaches 55 miles every hour to its destination.
Part C: What would be the domain of the function if the truck continued to travel at this rate until it reached its destination?
The linear equation that represents the problem is:
y = -55x + 330
For y = 0 we have:
0 = -55x + 330
Clearing x:
x = 330/55
x = 6
The domain of the function will be:
[0, 6]
Answer:
Step-by-step explanation:
let the smaller square be A, and the side is a
larger square is B, the side is a+3
Area(A)=a^2
Area(B)=(a+3)^2
a^2+(a+3)^2=425 in^2
a^2+a^2+6a+9=425
2a^2+6a=425-9
2(a^2+3a)=416 we divide by 2
a^2+3a=208
we solve the quadratic function
we will get two roots, a(1)=13, and the negative answer we will ignore
a=13 and the side of the larger square is 13+3=16
If this is geometry and youre just doing this now then I am guessing your school is going pretty slow at teaching you, and adjacent is the word youre looking for
As ordered pairs ( g , C ) where g is the number of games and C is the cost
( 5, 20.50) and ( 9, 28.50)
the slope M = ( 28.50 - 20.50 ) / (9-5)
= 8/4
= 2
So the slope M=$2 per game
Using (5, 20.50)
The intercept B = y - m* g
= 20.50 - 2 * 5
= 20.50 - 10
= 10.50
So the fixed base cost, or FLAT RATE is $10.50.
That is if they played ZER0 games, they still have
to pay $10.50 just to get in.
The linear function is C (g) = 2*g + 10.50
Answer:
Radical
Step-by-step explanation:
R is an abbreviation for radical, when the term radical applied to a portion of a complete molecule (not necessarily a free radical), such as a methyl group.
