Answer:
Step-by-step explanation:
We want to find the equation of a parabola withfocus at (-3,0) and directrix y=3.
This para has its vertex at the origin and opens downward.
The equation is of the form
Where p is the distance from the vertex to the focus.
This distance is p=|0-3|=3
We substitute p=3 to obtain:
Hence the equation is
Answer:
see the explanation
Step-by-step explanation:
we know that
A linear function in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept
x is the independent variable or input value
f(x) is the dependent variable or output value
In this problem we have
where
m is the number of miles
f(m) is the cab company's fare in dollars
we have that
In this context
<em>Slope</em>
The slope or unit rate is equal to the cost per mile for the riders trip
The slope is $3 per mile
<em>Y-intercept</em>
The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.
The y-intercept is $5
Answer:
<u>Option ⇒ </u>
Step-by-step explanation:
Given that ⇒
To rationalizing the denominator, we need to make a perfect cube under cube root of the denominator
∴ By multiplying the denominator and numerator by ∛(s²t)
∴
<u>The answer is the first option</u>
