A^2 = 4 and B^2 = 3. What is C^2 × 15?
adoni [48]

Answer:

105

Step-by-step explanation:

Assuming A^2 + B^2 = C^2:

C^2 = 4 + 3 = 7

So,

C^2 * 15 = 49(15) = 105

Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given
Rom4ik [11]

f'(x)\ge0 for all x in [-3, 0], so f(x) is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at x=-3.

From the plot, it's clear that on [-3, 0] we have f'(x)=-x. So

f(x)=\displaystyle\int(-x)\,\mathrm dx=-\dfrac{x^2}2+C

for some constant C. Given that f(0)=7, we find that

7=-\dfrac{0^2}2+C\implies C=7

so that on [-3, 0] we have

f(x)=-\dfrac{x^2}2+7

and

f(-3)=\dfrac52=2.5

During the summer, Hector does yard work, and Geri babysits.To show their earnings, Hector makes a graph, and Geri makes a table
VLD [36.1K]

I think that when you asked this question, no one answered because there is not enough information. I also got this problem and there is in fact, a table and a graph.

Step-by-step explanation:

for Hector, it only shows a y and x graph and for Geri it shows a table. let´s call the graph the ¨h¨ graph (for Hector) and the table is going to be called the ¨g¨ graph (for Geri)

on the h graph, it shows that y/x = dollars/time for Hector,

on the g table, it shows that Geri is getting paid $25.50 for each 3 hours and it keeps increasing within each input and output.

your y = your dollars

your x = your time

we are looking for slope and we need $15 over hours

15/x

the answer is that Hector earns $6.50 more than Geri
