2.$1.75
Step-by-step explanation:
The constant of proportionality is 2.5
Answer:
f(t) = $67000(.30)^t (Must use " ^ " to indicate exponentiation)
Step-by-step explanation:
This is an exponential function:
f(t) = $67000(.30)^t (Must use " ^ " to indicate exponentiation)
(y^2 + 7y +12) / (y^2+8y +15)
factor both equations:
(y+3)(y+4) / (y+3) (y+5)
cancel out common factors to get:
y+4 / y+5
Answer:
The y-intercept for this equation is 22.
Step-by-step explanation:
You can solve this quite easily by assigning a zero value to x and solving for y. That is where the curve will intersect the x-axis:
y = 2(x - 3)² + 4
y = 2(x² - 6x + 9) + 4
y = 2x² - 12x + 18 + 4
y = 2x² - 12x + 22
<em>EDIT</em>
<em>Note that the expression above is in standard form, though it can also be factored if needed:</em>
<em>y = 2(x² - 6x + 11)</em>
Now we can solve for an x value of zero:
y = 2(0)² - 12(0) + 22
y = 22
So the y-intercept is 22.
