For the function graphed below, identify the domain, range, intercepts, relative extrema, and end behavior. Find the intervals w

Anna11 [10]

Answer:

domain = (-∞,∞)

range = (-∞,∞)

y intercepts = (0,5)

x intercepts = (0,8)

increasing = (-∞,-8)∪(-4,2)∪(6,∞)

decreasing = (-8,-4)∪(2,6)

negative = (-∞,-2) or (-∞,-8)∪(-8,-2)

positive = (-2,∞)

Step-by-step explanation:

I'm pretty sure on everything but the negative because it does hit the x axis which makes the point (0,-8). But I'm pretty sure one of those is correct.

A certain NYC taxi driver has decided to start charging a rate of r cents per person per mile. How much, in dollars, would it co

katrin2010 [14]

Answer:

$\frac{3xr}{200}$

Step-by-step explanation:

A certain NYC taxi driver has decided to start charging a rate of r cents per person per mile

rate is cents . convert it in to dollars

1 cent = 1/100 dollars

r cents = r/100 dollars

Each people travels x miles

cost is $\frac{r}{100} \cdot x$

For 3 people the cost is

$3\frac{r}{100} \cdot x$

Discount is 50%, so we divide by 2

$\frac{3\frac{r}{100} \cdot x}{2} =\frac{3xr}{200}$

Pls show work. 3.14 for pi

stepan [7]

The easiest way to do this is to split each figure into smaller shapes.
1. a rectangle and a triangle
2. 3 separate rectangles
3. triangle and rectangle
... so on
You then find the areas of the smaller shapes and then add them together.
1. (for rectangle) 6*3 = 18
(for triangle) (12*15)/2 = 90 90 + 18 = 108
2. 4*8 = 32
8*4 = 32
12*12 = 144 32 + 32 + 144 = 208
...so on

at a country concert,the ratio of number of the Boys to the number of girls is 2:7 if there are 250 more girls than boys how man

sergey [27]

Answer:

100

Step-by-step explanation:

Ratio is a fraction, so ratio of boys to girls would be written as [let boys be "b" and girls be "g"]:

$\frac{b}{g}=\frac{2}{7}$

Also, there are 250 more girls than boys, so we can write:

g = 250 + b

Lets substitute this into "g" of the ratio we wrote and cross mulitply and solve for b:

$\frac{b}{g}=\frac{2}{7}\\\frac{b}{250+b}=\frac{2}{7}\\7b=2(250+b)\\7b=500+2b\\5b=500\\b=\frac{500}{5}=100$

The number of boys = 100
