What is the distance between the points 4,10 and -3,-14 on the coordinate plane

Mathematics
1 answer:
Kryger [21]3 years ago

Answer:

25

Step-by-step explanation:

Here we are supposed to find the distance between two coordinates ( 4,10) and (-3,-14).

Let us do this step by step with detailed explanation.

We will use distance formula in order to find the distance between them. The distance formula is given as

D=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }

Here we have

x_{2}=-3\\x_{1}=4\\y_{2}=-14\\y_{1}=10\\

Replacing them in the formula we get

D=\sqrt{(-3-4)^{2} +(-14-10)^{2} }\\D=\sqrt{(-7)^{2} +(-24)^{2} }\\D=\sqrt{49+ 576 }\\D=\sqrt{625 }\\D=25\\

Hence our distance is 25 units

Find an inverse of 16 modulo 17. That is solve 16x=1(mod 17)
mote1985 [20]

Answer:

-1 is the inverse of 16 modulo 17.

Step-by-step explanation:

To find : An inverse of  16 modulo 17 i.e. 16x=1(mod 17)?

Solution :

First we find the GCD of (17,16) using Euclid's algorithm,

17=16\times 1+1

Remainder is 1.

Which means, GCD(17,16)=1

Using back substitution we get,

1=17-16(1)

\Rightarrow 16(-1)=1+17(-1)

\Rightarrow 16(-1)=1(\mod 17)

i.e. -1 is the inverse of 16 modulo 17.

On comparing with 16x=1(mod 17)

The value of x=-1.

Gohan earned scores of 95, 100, 65, 95, 75, 98, 100, 55, 100, 45 on his last ten quizzes. What is the mean of his quiz scores? W
irinina [24]

Answer: Mean= 82.8

Median= 95

Mode=100

Step-by-step explanation:

Mean is the average of the scores

Mean= 95+100+65+95+75+98+100+55+100+45 =828/10= 82.8

To get the median, we rearrange the numbers in either ascending or descending order.

45,55,65,75,95,95,98,100,100,100

Median= 95

Mode is the number that occurs most which is 100

Does, this make any sense to anyone? I honestly don't understand it. I'm learning functions by the way.

<h3>Answer:     t = 7</h3>

===========================================================

Explanation:

If we replace every copy of x with t, then we go from this

F(x) = 3x+5

to this

F(t) = 3t + 5

All we've done really is change the letter. We still are dealing with a variable. We're told that F(t) is equal to 26, which would allow us to replace the "F(t)" with "26" in the second equation above.

So we now have the equation 26 = 3t+5 which is the same as 3t+5 = 26

Let's solve for t

3t+5 = 26

3t = 26-5 .... subtract 5 from both sides

3t = 21

t = 21/3 .... divide both sides by 3

t = 7  is the answer

Now note that...

F(t) = 3t + 5

F(7) = 3*7 + 5 .... replace t with 7

F(7) = 21 + 5

F(7) = 26

This means we got F(t) = 26 when t = 7

It's the same as saying x = 7 leads to F(x) = 26.

This helps confirm we have the correct answer.
