Consider the function y=x^2+5x-2 . What would happen to the graph if (x -1) was substituted in place of the x?
Ilia_Sergeevich [38]

Answer:

B.

Step-by-step explanation:

f(x - c) shift the function <em>c</em> units to the right.

In this case, if (x - 1) was substituted in place of the x, the graph would shift 1 unit to the right.

If you want to graph the new function and know the graph of the previous one, this relationship avoids you the substitution of (x - 1) into the function and expansion of the expression to obtain a new quadratic formula.

Which piecewise function represents the graph?
Anon25 [30]

Answer:

D

Step-by-step explanation:

If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x <u>></u> 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.

Hope this helps! :)

How do I find a percent out f three numbers that are not percents
drek231 [11]
"Turn the two numbers into a fraction; place the number you want to turn into a percentage over the whole value. Convert the fraction into a decimal. Multiply the decimal by 100 to get the percent."

What is 5.8×10^6 mg/s in grams per minute? A. 9.7×10^9 g/min B. 9.7 × 10^7 g/min C. 3.48 × 10^5 g/min D. 3.48 × 10^3 g/min.
Luda [366]
1 second = 5.8x10^6 mg
60 seconds = 5.8x10^6 x 60 = 3.48x10^8 mg
(i.e 3.48x10^8 mg/minute)

1000 mg = 1 g
3.48x10^8 mg = 3.48x10^8/1000 = 3.48x10^5 g

Therefore, 5.8x10^6 mg/s = 3.48x10^5 g/min
