Answer:

X2 = 1.0792

Y2 = 2.0594

ΔX = 4.0792

ΔY = 3.0594

θ = 36.869897645844°

Equation of the line:

y = 0.75x + 1.25

When x=0, y = 1.25

When y=0, x = -1.6666666666667

X2 = -7.0792

Y2 = -4.0594

ΔX = -4.0792

ΔY = -3.0594

θ = 216.86989764584°

Equation of the line:

y = 0.75x + 1.25

When x=0, y = 1.25

When y=0, x = -1.6666666666667

What are the apparent zeros of the function graphed above ?

gregori [183]

Answer:

$-2,1,4$

Step-by-step explanation:

we have

$y=x^{3}-3x^{2} -6x+8$

we know that

The zeros of the function are the values of x when the values of the function is equal to zero

In this problem the apparent zeros are

For $x=-2$

$y=0$

For $x=1$

$y=0$

For $x=4$

$y=0$

Answer:

dont even stress i gotchu

It's 50*, 46* and 84*.

Ratio of the second problem is 1:1 they both have a slope of 1 (which is probably why all three points are on the same line)

Step-by-step explanation:

Since we know that the straight/flat angle would equal 180* we will set the total of all those angles to 180*

We will add them up to find x. Once we find x we can find the value of each angle.

6x-10 + 4x + 6 + 7x + 14 = 180

We will combine like terms and solve for x.

17x+10 = 180

17x = 170

x = 10.

Since we have x = 10, we will plug it into x of each angle to get the value of each angle.

6(10) -10 = 60-10 which equals 50*

4(10) + 6 = 40+6 which equals 46*

7(10) + 14 = 70 + 14 which equals 84*.

Using any five itegers from 1 to 10 what is the greatest possible mean of the 5 numberes if the median is 4?

BartSMP [9]

That would a set of 5 numbers in ascending order with 4 being the middle one and the other 4 being the highest possible So it is

2, 3, 4, 9, 10

Mean is 28/5 = 5.6 answer

( I am assuming that each number is different)

Of duplicates is allowed then its 4 4 4 10 10 whose mean is 6.4

Hello I would really appreciate if someone could help me with this math question. I’m so confused

Katarina [22]

Answer:

a. f = 17.5/c

b. 8.75 N

Step-by-step explanation:

Inverse variation means one variable is proportional to the inverse of the other. The equation for that is ...

f = k(1/c) . . . . . . force (f) is proportional to the inverse of distance (c)

We find the value of k using data given for a specific instance.

3.5 N = k(1/(5 cm)) . . . . use the given values

17.5 N·cm = k . . . . . . multiply by the denominator

Then the equation of interest is ...

f = 17.5/c . . . . . . . where c is in cm, and f is in newtons

Using the above equation, we find the force to be ...

f = 17.5/2 = 8.75 . . . . newtons

_____

<em>Additional comment</em>

We often look at several different kinds of proportionality:

y = kx . . . . direct
y = k(1/x) . . . . inverse
y = kx² . . . . proportional as the square
y = kx·z . . . . jointly proportional to x and z

and there are combinations of these, such as ...

y = kr²h . . . . jointly proportional to h and the square of r

You may have noticed that when x and y are inversely proportional, their product is a constant. y = k/x ⇒ xy = k

We have left off the units of k in the problem above. Sometimes it is a good idea to retain them, or to pay close attention to what they are. This can avoid using the wrong measures for the variables.

f = (17.5 N·cm)/(2 cm) = 8.75 N . . . . . units of cm cancel

The Pool Company has learned that, by pricing a newly released Fun Noodle At $1, sales will reach 5000 Fun Noodles per day durin

Elenna [48]

Answer:

Step-by-step explanation:

lope is (13000-15000)/(5-3)=-2000/2=-1000

point slope formula: y-y1=m(x-x1), m slope and (x1,y1) a point

y-15000=-1000(x-3)

y-15000=-1000x+3000

y=-1000x+18000

when x=$3.50

y=-3500+18000=14,500 noodles predicted to be sold.
