Solve for x. X2 - 20x+ 100 = 0

Mathematics
1 answer:
lianna [129]2 years ago
8 0

Answer:

X will equal 10 x=10

Step-by-step explanation:

First subtract 100 from both sides to get x^2-20x=-100 then find c. (-b/2)^2 is the formula. then c=100 so add 100 to both sides. x^2-20x+100=200. Then Factor. (x-10)^2=0 is what you should get. then do square root. x-10=0. So now add 10 to both sides and you get x=10. Tada!

Does this graph represent a function? Why or why not?
DedPeter [7]

Answer: C

Step-by-step explanation: For a function, each x-coordinate corresponds to exactly one y-coordinate.

To determine whether the graph shown here

is a function, we can use the vertical line test.

The vertical line test tells us that if each x-coordinate on the graph corresponds to exactly one y-coordinate, then any vertical line that we draw on the graph should hit the graph at only one point.

For the graph show here, any vertical line that you draw with hit the graph at only one point which means it does pass the vertical line test.

So this graph is a <em>function</em>.

The length of a text messaging conversation is normally distributed with a mean of 2 minutes and a standard deviation of 0.5 min
zhenek [66]

Answer:

Let x be a random variable representing the length of a text messaging conversation, then

P(x > 3) = 1 - P(x < 3) = 1 - P(z < (3 - 2)/0.5) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275

iragen [17]

The length of the copy is 16.8 cm ,The length of the original is 25 cm.

<h3>What is Percentage ?</h3>

Percentage is a number or ratio that represents a fraction of 100

It is given that

A photocopier makes copies that are 40% larger than the original.

An original is 12cm long. Find the length of the copy.

The copy will be

140 % of 12 cm

140 * 12/100

16.8 cm

Therefore , the length of the copy is 16.8 cm.

A copy is 35cm long. Find the length of the original.

The original will be x

140 * x / 100 = 35

x = 35 * 100 / 140 = 25cm

The length of the original is 25 cm.
