Answer:
f(x)= 2x² - 4x + 3
Step-by-step explanation:
dy/dx = 4x - 4
y = integrate dy/dx
y = 4x²/2 - 4x + c
y = 2x² - 4x + c
at (2,3)
3 = 2(2)² - 4(2) + c
3 = 8 -8 + c
c = 3
therefore f(x)= y = 2x² - 4x + 3
Answer:
1/2<8/13
Step-by-step explanation:
1/2<8/13
Slope-intercept form can be written as
y = mx + b
From the question above, we should move x to another side (right side), so the left side only contains of y-variable
-3x + 2y = 12
2y = 12 + 3x
To make slope-intercept form, only y is on the left side. We should move the coefficient 2 to the right side.
2y = 12 + 3x
2y = 3x + 12
y = (3x + 12)/2
Simplify the equation
y = (3x + 12)/2
y = (3/2)x + 12/2
y = (3/2)x + 6
This is the final answer ⇒ y = (3/2)x + 6
We have to evaluate the unit rate for 1 Apple for $0.19.
The formula for unit rate is shown below.
Now, we have been given the cost of the apple is $0.19 and the number of unit is 1. Hence, using the above mentioned formula, the unit rate is given by
Therefore, the unit rate is 0.19 dollars per apple.
Answer:
Radius = 5.777 m
Step-by-step explanation:
Given that:-
The circumference of the circle = 36.31 m
The expression for the calculation of circumference is shown below as:
Thus,
Solving for radius, we get that:-
Radius = 5.777 m
<u>The approximate length of the radius is 5.777 m.</u>
