Answer:

G'(1, 3)

Step-by-step explanation:

Counterclockwise rotation 90°: (x, y) ⇒ (-y, x)

So the point G is transformed to ...

... G(3, -1) ⇒ G'(1, 3)

Ava earns $ 3 for every cup of lemonade she sells How many cups of lemonade does Ava need to sell in all to earn $ 24?
STatiana [176]

Answer:

Ava needs to sell 8 cups of lemonade to earn $24.

Step-by-step explanation:

This is actually just a simple multiplication question. How many times do we need to multiply 3 to get 24? 3 x 8 is 24, and therefore we can conclude Ava needs to sell 8 cups of lemonade to earn $24.

What are the approximate values of the minimum and maximum points of f(x) = x5 − 10x3 + 9x on [-3,3]? A. maximum point: (–2.4, 3
slava [35]

Answer:

(-2.4, 37.014)

Step-by-step explanation:

We are not told how to approach this problem.  

One way would be to graph f(x) = x^5 − 10x^3 + 9x on [-3,3] and then to estimate the max and min of this function on this interval visually.  A good graph done on a graphing calculator would be sufficient info for this estimation.  My graph, on my TI83 calculator, shows that the relative minimum value of f(x) on this interval is between x=2 and x=3 and is approx. -37; the relative maximum value is between x= -3 and x = -2 and is approx. +37.  

Thus, we choose Answer A as closest approx. values of the min and max points on [-3,3].  In Answer A, the max is at (-2.4, 37.014) and the min at (2.4, -37.014.

Optional:  Another approach would be to use calculus:  we'd differentiate f(x) = x^5 − 10x^3 + 9x, set the resulting derivative = to 0 and solve the resulting equation for x.  There would be four x-values, which we'd call "critical values."
