Answer:
Sarita is wrong, the correct equation is
Step-by-step explanation:
we know that
The equation of a line in slope intercept form is equal to
we have
substitute in the equation
Solve for m
substitute
therefore
Sarita is wrong
Answer:
No, it is a parabola. (assuming that you meant to write 6x² - 2y = 7).
Step-by-step explanation:
If there is a square in the x or y, this gives it away that it cannot be a straight line.
Answer:
The diameter decreases at a rate of -0.0477 cm/min when it is 10 cm.
Step-by-step explanation:
Surface area of a snowball:
A snowball has a spheric format, which means that it's surface area is given by:
In which r is the radius, which is half the diameter. In function of the diameter, the area is given by:
Solving the question:
To solve this question, we have to implicitly derivate the area in function of t. So
Snowball melts so that its surface area decreases at a rate of 3 cm2/min
This means that
Find the rate at which the diameter decreases when the diameter is 10 cm.
This is when . So
The diameter decreases at a rate of -0.0477 cm/min when it is 10 cm.
