613.6 would be the answer. I got it by multiplying 2.5 and 104 together to get 260, then I multiplied 3.4 and 104 together getting 353.6. I then added 260 and 353.6 together to get 613.6.


2.5 * 104 = 260
3.4 * 104 = 353.6
353.6 + 260 = 613.6

Below is the graph of f ′(x), the derivative of f(x), and has x-intercepts at x = –3, x = 1 and x = 2. There are horizontal tang
guapka [62]

the derivitive is just the slope

minimum happens when the derivitive goes from negative to positive, imagine a slope of the function, the minimum is where the slope goes from neative to positive, and to get there, it has to pass through 0

max happens when the derivitive goes from positive to negative

increaseing is when the derivitive is positive



so, based on what you said, the slope of f(x) is 0 at x=-3, x=1 and x=2 since those are where the derivitive is 0 (derivitive is just the slope)

A and B are wrong because the derivitive isn't 0 at those points

C is correct because increasing means that the derivitive is positive, and so therefo since the only hoirontal place in between 1 and 2 is 1.5, it must remain positive throughout and not dip down, C is right

D is wrong then




answer is C

1.7 In the following diagram, angle 7 equals 61°.
gladu [14]
1.7) < 7 and < 8 form a linear pair....which means, when added, they equal 180 degrees. So if < 7 = 61, then < 8 = (180 - 61) = 119 <=

1.8) angles that are supplementary will add up to 180. So if one of the angles is 38, then the other one is (180 - 38) = 142 <==

1.9) < 3 = < 5 (vertical angles are congruent)
1.10) < 2 = < 8 (vertical angles are congruent)
1.11) < 7 = < 1 (vertical angles)
1.12) < 6 = < 4 (vertical angles)

Write a multiplication equation that represents the question: how many 3/8 are in 8?
goldenfox [79]

Answer:

8

Step-by-step explanation:

\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8} +\frac{3}{8}

\frac{3}{8} × 8

= 3

In algebra:

\frac{3}{8} × y = 3

y = 3 ÷ \frac{3}{8}

y = 8
