Find the distance between (10, 12) and (1,0

Mathematics
1 answer:
Luba_88 [7]3 years ago
8 0

Answer:

The desired distance is 15 units.

Step-by-step explanation:

Note how x increases from 1 to 10 and y from 0 to 12 at the same time.

Using the Pythagorean Theorem, we find that the distance between the two points is the length of the hypotenuse, which is

d = √[ (10 - 1)^2 + (12 - 0)^2 ],  or  d = √ [81 + 144] = 225 = +15

The desired distance is 15 units.

1.A rectangle is 6 inches longer than its wide.Write and simply an expression for the perimeter of the rectangle.
iris [78.8K]
P = 2L + 2W
L = W + 6
P = 2(W + 6) + 2W
P = 2W + 12 + 2W
P = 4W + 12

5 + 2(3x + 4) + x
5 + 6x + 8 + x
5 + 8 + 6x + x
13 + 7x Stop Don't go any further. That's the 11th commandment: Thou shalt not combine unlike terms.

Paul has a long drive. If Shelly waits up she better have some snacks
4*65 + x = 500 The x stands for the number of miles left to go
270 + x = 500 Subtract 280 from both sides
x = 500 - 270
x = 230

Just so you know if he keeps going at 65 mph the amount time will be
230/65 = 3.53 hours.

For f(x)=x^2,sketch the graph of g(x)=f(-5x+10)
DiKsa [7]

The graph of g(x) = f(-5x+10) is given in the figure.

<h3>What is a graph?</h3>

A diagram showing the relation between two variable quantities,each measured along one of a pair of axes at right angles.

It is given that f(x) = x^2

and g(x ) = f(-5x+10)

Now putting the value of f(x) in g(x) we get,

g(x)  = f(-5x+10)  = (-5x+10)^2

So, g(x) = (-5x+10)^2

now, making the table for g(x),

<u><em>x </em></u><u>g(x)</u>

0 100

1 81

2 0

3 25

4 100

5 225

Hence,the graph of g(x) = f(-5x+10) is given in the figure.

What is the y-intercept of this function?<br> f(x) = 2(x - 7)2 – 32
LUCKY_DIMON [66]

We are given the following function and want to find the y-intercept:

f(x)=2(x-7)^2-32

Just substitute the value x=0 into the equation to find the value of the y-intercept:

y=2(0-7)^2-32

Simplify

=2(49)-32

Simplify again

=66

Since the value of f(x), or y, when x=0 is 66, the y-intercept of this function is 66.

Let me know if you need any clarifications, thanks!

A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two
Vikentia [17]

Answer:

the probability of no defects in 10 feet of steel = 0.1353

Step-by-step explanation:

GIven that:

A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two.

Let consider β to be the average value for defecting

So;

β = 2

Assuming Y to be the random variable which signifies the anticipated number of defects in a 10-foot segment of this roll.

Thus, y follows a poisson distribution as number of defect is infinite with the average value of β = 2

i.e

Y \sim P( \beta = 2)

the probability mass function can be represented as follows:

\mathtt{P(y) = \dfrac{e^{- \beta} \ \beta^ \ y}{y!}}

where;

y =  0,1,2,3 ...

Hence,  the probability of no defects in 10 feet of steel

y = 0

\mathtt{P(y =0) = \dfrac{e^{- 2} \ 2^ \ 0}{0!}}

\mathtt{P(y =0) = \dfrac{0.1353  \times 1}{1}}

P(y =0) = 0.1353
