Answer:

N= 4

Step-by-step explanation:

y^3 * y^n

_______  = y^6    

   y

First we multiply the 2 y's together to get

y^n+3

____         = Y^6

Y

Then we will multiply y to both sides

y^n+3 = y^7

Get rid of y

n+3 = 7

n=4

Shannon test-drives a car in Germany and drives 95 kilometer per hour. What is her speed in miles per hour? (1 kilometer < 0.
victus00 [196]

Answer:

58.9 miles per hour

Step-by-step explanation:

Step 1: Convert 95 Kilometers per hour to miles per hour

1 Kilometer = 0.62 miles

95 Km x \frac{0.62 miles}{1 km}

cancel Km

95 Km x \frac{0.62 miles}{1 km}  = \frac{95}{1} x \frac{0.62 miles}{1} = \frac{58.9 miles}{1} or 58.9 miles

Change it into speed

58.9 miles per hour (59 miles per hour (Round off))

(Note: I don't know if I should round off because the instructions aren't that clear. This solution might or might not have been thought to you by your lecturer.)

I need to find the slope, vertical intercept and horizontal intercept of these 3 linear functions:
Bumek [7]
These are in y=mx+b form where m=slope
sometimes b=0

vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is

y=5x-15
slope=5
y-intercept=-15
x-intercept=3

y=7-x
this can be written as
y=-1x+7
slope=-1
y-intercept=7
x-intercept=7

4x=2y=12
we must get it into slope intercept form
divide the whole thing by 2x=y=12
 we can disregard the 12 and get
2x=y or y=2x+0
slope=2
y-intercept=0
x-intercept=0

Differentiating Functions of Other Bases In Exercise, find the derivative of the function.
aniked [119]

Answer:

\dfrac{dy}{dx} = \frac{2x-3}{\ln 16(x^2 - 3x)}

Step-by-step explanation:

We are given the following in the question:

y = \ln {16}(x^2 - 3x)

We have to find the derivative of the given expression.

y = \ln 16(x^2 - 3x)\\\text{Using the log propert}\\\\\log_a b = \dfrac{\log b}{\log a}\\\\dfrac{d(x^n)}{dx} = nx^{n-1}\\\\\dfrac{d(\log x)}{dx} = \dfrac{1}{x}\\\\\text{\bold{Differentiating we get}}\\\\\displaystyle\frac{dy}{dx} = \frac{d(\ln 16(x^2-3x))}{dx}\\\\= \frac{1}{16(x^2-3x)})\frac{d(x^2-3x)}{dx}\\\\=\frac{1}{\log 16(x^2-3x)}(2x - 3)\\\\= \frac{2x-3}{\ln 16(x^2 - 3x)}

\dfrac{dy}{dx} = \frac{2x-3}{\ln 16(x^2 - 3x)}
