Answer:

y = 4x² -19x -5

Step-by-step explanation:

When you graph it (or use an appropriate tool), it can help us to figure out that the equation is:

y = 4x² -19x -5

(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

Hope this helps, have a nice day :D

Answer:

A. you need 2 1/2 ounces

B. you need 73,9 milliliters

Step-by-step explanation:

We have the ratio 1/2 ounces per gallon

And the mop bucket holds 5 gallons

Then we need to multiply 1/2*5

we got 2 1/2 ounces of desifectant per 5 gallons

1 ounces equal 29,57 milliliters

if we have 2 1/2 ounces then we multiply 2,5 *29,57

the answer is 73,9 milliliters

Answer:

$a = 6\sqrt 3,\:\:b =12,\:\:c=6\sqrt 2$

Step-by-step explanation:

$by \: 30 \degree - 60 \degree - 90 \degree \: theorem \\ \\ 6 = \frac{1}{2} b\\ \\ 6 \times 2 = b \\ \\ 12 = b \\ \\ \huge\red {\boxed {b= 12}} \\ \\ a = \frac{ \sqrt{3} }{2} b \\ \\ a = \frac{ \sqrt{3} }{2} \times 12 \\ \\ \huge\purple {\boxed {a = 6 \sqrt{3}}} \\ \\ c = \frac{1}{ \sqrt{2} } b \\ \\ c = \frac{1}{ \sqrt{2} } \times 12 \\ \\ c = \frac{ \sqrt{2} }{2} \times 12 \\ \\ \huge\orange {\boxed {c = 6 \sqrt{2}}} \\ \\$

A one-stop flight from seattle to nyc can stop at boise, omaha, or chicago. the flight then connects to either la guardia or jfk

Sindrei [870]

The first and only stop of the flight can be Boise, Omaha or Chicago. This means there are 3 possibilities where to stop. From thee the flight connects to New York City, either to La Guardia or to JFK Airport.
1 possible route: Seattle-Boise-La Guardia
2 possible route: Seattle-Omaha-La Guardia
3 possible route: Seattle-Chicago-La Guardia
4 possible route: Seattle-Boise-NYC
5 possible route: Seattle-Omaha-NYC
6 possible route: Seattle-Chicago-NYC

Or in other words: There are two airports where the flight can arrive and for each of them there are three possible routes. So, in total there are 2*3=6 possible routes.
