What graph best represents y=2^x + 1

Citrus2011 [14]

Answer:

The graph that best represents the given equation in the attached figure

Step-by-step explanation:

we have

$y=2^x+1$

Find the y-intercept

Remember that the y-intercept is the value of y when the value of x is equal to zero

For x=0

substitute

$y=2^0+1=2$

The y-intercept is the point (0,2)

The given function is increasing, because the y-value increases as the x-value increases. The function tends to go up as it goes along

therefore

The graph that best represents the given equation in the attached figure

PLEASE HELP ASAP!!!!!!Ms. Banerjee bought a car for $22,500. The amount she paid for her new car was twice the amount she paid f

ZanzabumX [31]

Answer:

22,500 =2p

Step-by-step explanation:

Because the price of the new car is the price of the old car times 2.

22,500 =2p

First you get P alone. P is being multiplied by 2 so you divide it by 2 so it cancels out.

11250 = p

When you do something to one side of the equation you do the same to the other side so they are still equal to each other.

A factory produces widgets whose length must be within 1.5 mm of an ideal length of 47 mm. A factory supervisor wants to mark ru

Nat2105 [25]

Using absolute value, it is found that:

The situation is described by the following equation: $|l - 47| = 1.5$
The markings should be between 45.5mm and 48.5mm.

---------------------------

The definition of the <em>absolute value function</em> is as follows:

$|x| = x, x \geq 0$

$|x| = -x, x < 0$

----------------------------

The length should be set to 47mm with an allowance of 1.5mm, which means that <u>the absolute value of the difference between the length and 47 should be 1.5</u>, thus:

$|l - 47| = 1.5$

----------------------------

The solutions are:

$l - 47 = -1.5 \rightarrow l = 45.5$

$l - 47 = 1.5 \rightarrow l = 48.5$

The markings should be between 45.5mm and 48.5mm.
