Janine needs to calculate the value of log12 81
Which expressions could she input into her calculator to find this value?

Answer:

A. 0 and 4

Step-by-step explanation:

The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.

Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.

x-intercepts are 0 and 4.

0

Answer:

Length of mammoth's tusk in  poster = 15.33

Step-by-step explanation:

Actual height of mammoth = 10 feet 5 inches = 126 inches

Height on the poster of mammoth = 14 inches

Actual length of mammoth's tusk = 11.5 feet = 138 inches

Length of mammoth's tusk in  poster = x

126 : 14  :: 138  : x

Product of mean = product of extremes

x * 126 = 14 * 138

[tex]x = \frac{14*138}{126}[/tex]

x = 15.33

Answer:

I=P0r  

A=P0+I=P0+P0r=P0(1+r)  

I  is the interest

A  is the end amount: principal plus interest

P0  is the principle (starting amount)

r  is the interest rate (in decimal form. Example: 5%=0.05)

Step-by-step explanation:

if 8 oranges cost 1 dollars

4 oranges cost 1/2=0.50 cents

one dozen=4*3= 12 oranges

0.50*3=1.50 dollars/dozen

4 dozen=4*1.50=6 dollars

Cost = $6.00

EXPLANATION:

0 = 1 orange

0 0 0 0 0 0 0 0 = 8 oranges = $1.00

1 dozen = 12 (oranges)

4 dozens = 48 (oranges)

0 0 0 0 0 0 0 0 = $1 (1)

0 0 0 0 0 0 0 0 = $1 (2)

0 0 0 0 0 0 0 0 = $1 (3)

0 0 0 0 0 0 0 0 = $1 (4)

0 0 0 0 0 0 0 0 = $1 (5)

0 0 0 0 0 0 0 0 = $1 (6)

I divided the 48 oranges in groups of 8.

One group of 8 oranges equals $1.

There was a total of 6 groups of 8 oranges, without any leftovers.

The Total Is $6.

Pie charts can generally be used instead of bar graphs

Step-by-step explanation:

A pie chart can be used instead of a bar chart. A pie chart is an alternative to the bar chart. Both of these can be regarded as data visualization tools. The pie chart shoes us generally how several parts makes up a whole. While the bar chart uses rectangular bars to show us the proportion of each of the categories of data

The statement which is true among the given group of options is; Pie charts can generally be used instead of bar charts.

Pie charts can be used as substitutes for bar charts. This stemmed from.the fact that both tools are data visualization tools.

On this note, pie charts can be used to replace the bar charts even though pie charts entails dividing the 360° angle in a circle in respective ratios.

You need to find the WPM (words per minute) of each person.

Andre - 208 divided by 4 = 52

Noah - 342 divided by 6 = 57

You now know that Andre types 52 words per minute and Noah types 57 words per minute.

Answer: Noah types faster because he types 57 words per minute while Andre types 52 words per minute.

Answer:Noah types faster.

Step-by-step explanation: For Andre ,You do 208 divide 4 which gives you 52.For Noah, you do 342 divide by 6 which gives you 57.And since Noah  type more words which is 57  while Andre type 52, that means Noah types faster.

Graph Transformations

There are many times when you’ll know very well what the graph of a

particular function looks like, and you’ll want to know what the graph of a

very similar function looks like. In this chapter, we’ll discuss some ways to

draw graphs in these circumstances.

Transformations “after” the original function

Suppose you know what the graph of a function f(x) looks like. Suppose

d 2 R is some number that is greater than 0, and you are asked to graph the

function f(x) + d. The graph of the new function is easy to describe: just

take every point in the graph of f(x), and move it up a distance of d. That

is, if (a, b) is a point in the graph of f(x), then (a, b + d) is a point in the

graph of f(x) + d.

As an explanation for what’s written above: If (a, b) is a point in the graph

of f(x), then that means f(a) = b. Hence, f(a) + d = b + d, which is to say

that (a, b + d) is a point in the graph of f(x) + d.

The chart on the next page describes how to use the graph of f(x) to create

the graph of some similar functions. Throughout the chart, d > 0, c > 1, and

(a, b) is a point in the graph of f(x).

Notice that all of the “new functions” in the chart di↵er from f(x) by some

algebraic manipulation that happens after f plays its part as a function. For

example, first you put x into the function, then f(x) is what comes out. The

function has done its job. Only after f has done its job do you add d to get

the new function f(x) + d. 67Because all of the algebraic transformations occur after the function does

its job, all of the changes to points in the second column of the chart occur

in the second coordinate. Thus, all the changes in the graphs occur in the

vertical measurements of the graph.

New How points in graph of f(x) visual e↵ect

function become points of new graph

f(x) + d (a, b) 7! (a, b + d) shift up by d

f(x) Transformations before and after the original function

As long as there is only one type of operation involved “inside the function”

– either multiplication or addition – and only one type of operation involved

“outside of the function” – either multiplication or addition – you can apply

the rules from the two charts on page 68 and 70 to transform the graph of a

function.

Examples.

• Let’s look at the function • The graph of 2g(3x) is obtained from the graph of g(x) by shrinking

the horizontal coordinate by 1

3, and stretching the vertical coordinate by 2.

(You’d get the same answer here if you reversed the order of the transfor-

mations and stretched vertically by 2 before shrinking horizontally by 1

3. The

order isn’t important.)

Answer:

The answer is 5/4

Step-by-step explanation:

Answer:

The y-intercept for this equation is 22.

Step-by-step explanation:

You can solve this quite easily by assigning a zero value to x and solving for y.  That is where the curve will intersect the x-axis:

y = 2(x - 3)² + 4

y = 2(x² - 6x + 9) + 4

y = 2x² - 12x + 18 + 4

y = 2x² - 12x + 22

EDIT

Note that the expression above is in standard form, though it can also be factored if needed:

y = 2(x² - 6x + 11)

Now we can solve for an x value of zero:

y = 2(0)² - 12(0) + 22

y = 22

So the y-intercept is 22.

Answer:

The 95% confidence interval for the population mean is between $140.89 and $159.11.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96\frac{36}{\sqrt{150}} = 9.11[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 150 - 9.11 = $140.89

The upper end of the interval is the sample mean added to M. So it is 150 + 9.11 = $159.11

The 95% confidence interval for the population mean is between $140.89 and $159.11.
