Answer:

Step-by-step explanation:

A function is an equation which results in 1 y value for every x value,

Therefore lets eliminate the answers that have repeating x values

A - This is a function, all x values have one output (y value)

B - This is not a function, the x value of 1 repeats meaning theres

more than 1 corresponding output or y value

C - This is not a function, the x value 0 repeats

D - This is not a function, the x value(s) -1 and -2 repeat

Therefore A represents a function and the others do not.

Hope this helps

Answer:

Step-by-step explanation:

a function is when the value of x is not repeated

in the other choices you can see that some coordinates have different y-values but some of the x-values are the same

A is the only one in which the x-value is not repeated

Dy/dx e^8x= sin (x+4y)

WINSTONCH [101]

Implicit differentiation:
differentiate both sides,
8e^(8x)=cos(x+4y)(1+4y')
Solve for y' to get
y'=[cos(x+4y)-8e^(8x)]/[4cos(x+4y)]

Answer:

The linear function is $y=50x+20$

The reasonable domain is $0\ hours \leq x\leq 2\ hours$

Step-by-step explanation:

Let

x ----> the time in hours

y ---> the distance in miles

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The slope is $m=50\ \frac{miles}{hour}$

The y-intercept is $b=20\ miles$

substitute

$y=50x+20$

<em>Find the domain for x</em>

For y=120 miles

Find the value of x

substitute the value of y in the linear equation and solve for x

$120=50x+20$

$50x=120-20$

$50x=100$

$x=2\ hours$

therefore

The domain is the interval [0,2]

$0\ hours \leq x\leq 2\ hours$

Answer:

Circle D

Step-by-step explanation:

Circle A and B contain elements. We can tell because the circle only contains one type of substance. We can also conclude that A and B are probably diatomic elements. Circle C contains a compound. This leaves us with Circle D which contains a mixture as it has elements and compounds.

m∠H = 50°

∠H is a inscribed angle, and so that the intercepted arc would be twice the amount of the angle.

Arc KI = 100°

Because ∠KGI & ∠HKI share the same arc, the measurement for ∠KGI will be the same as ∠HKI, or 50°

m∠KGI = 50°

Next, find m∠KJI. arcKJI = 2(∠H) = 2(50) = 100

m∠KJI = 100°
