What is 49 to the negative power 1/2?

Answers

Answer 1
Answer: So say you have just 49 raised to the 1/2, that is equivocal to the square root of 49, which is 7. Instead, you have 49 raised to the negative half power, so all you need to do is move that term to the denominator of its fraction. You now have 1/49^(1/2) which turns out to be 1/7
Answer 2
Answer: 49^-1/2
=1/49^1/2
= 1/Square root of 49
=1/7

Median is the average. I'm pretty sure interquartile is the biggest number out of the two. 

Add the numbers for the first semester up, then divide by the amount of numbers. Do the same for semester two, then pick the correct answer in the multiple choices... For example in semester one you'd divide the added amount by 5.

Step-by-step explanation:

The statement that is not true (an exception is easily created) is C

Draw a 1 by 4 rectangle.

Underneath it draw a 2 by 2 rectangle.

They both have the same area (4 units) but they are not congruent. The corresponding lengths are not equal and that is another condition that must be met for there to be congruence. There are many others.

Draw a 2 by 2 square.

draw a triangle with a base of 1 and a height of 8. These two figures have the same area, but they don't even have the same number of sides.

C is simply not true.

Which rule represents the translation of hexagon DEFGHI to hexagon D'E'F'G'H'I'?(x, y)→(x - 8, y - 7)

(x, y)→(x - 7, x - 8)

(x, y)→(x - 4, x - 5)

(x, y)→(x - 5, y - 4)

(adding picture in a second)

Answers

We will choose two vertices of hexagon DEFGHI and hexagon D´E´F´G´H´I´:
D ( 2, 5 )  → D´( - 6 - 2 )
E ( 5, 5 )  → E ´( - 3. - 2 )
- 6 = 2 - 8,      - 2 = 5 - 7
- 3 = 5 - 8,      - 2 = 5 - 7
Answer: A) ( x, y )→ ( x-8,  y-7 )

Answer:

A. (x, y)→(x − 8, y − 7)

1/2
B.
8/14

C.

1/3
D.
2/7

Answers

1/2 because 14/28 simplifys down to 1/2 enjoy!=)
well 7 goes into both of those numbers so 14 divided by 7 is 2 and 28 divided by 7 is 4 so the answer is 2/4 which equals 1/2 so its A.

Hi, can anyone graph y=15x+75?

Answers

Answer:

Graph

Step-by-step explanation:

The simplest way to graph a linear equation is to make an x, y chart.

Plug in values for x ( 3 values for x works ), then find the y values and graph the cordinates.

Another way to graph the above line is to identify the slope and the y-intercept. Because the function is in slope-intercept form, we can readily see both ( slope intercept form is y= mx + b where m= slope and b= y-intercept )!  So b= 75 and m= 15. So to graph the y-intercept, it is ( 0, b ) and just count the slope from that point!

Final answer:

To graph the equation y = 15x + 75, start by plotting the y-intercept (0,75). Then move 15 units up and 1 to the right from the intercept. Connect the points to create the graph.

Explanation:

To graph the equation y = 15x + 75, you need to recognize it as the linear equation in slope-intercept form, y = mx + b. In this equation, m (slope) is 15 and b (y-intercept) is 75.

Start by plotting the y-intercept which is at the point (0, 75) on the y-axis. Then, from that initial point, use the slope or 'rise over run,' to find the next points. Given the slope is 15 (or 15/1), you will go up 15 units and right 1 unit from the intercept to plot your next point. Continue this process until you have enough points to produce a straight line.

By connecting these plotted points, you create the graph of y = 15x + 75.
