Distance between (-1,2) (7,8)

Answers

Answer 1
Answer:
The distance between any two points is

       square root of ( [difference in the 'y's]² + [difference in the 'x's]² )

Difference in the 'y's =  8 - 2  =  6
Difference in the 'x's =  7 - (-1)  =  8

Distance between them =

           square root of  ( 6² + 8² )  =

           square root of  ( 36 + 64 )  =

           square root of  ( 100 )  =  10 .

Answer 2
Answer:

Answer: 10

Step-by-step explanation: In this problem, we're asked to find the distance between the points (-1,2) and (7,8) so we use the distance formula which states that the distance between two points is equal to

d =\sqrt{(x^(2) - x^(1))^(2) + (y^(2) - y^(1))^(2)    }.

Our first point, (-1,2) represents (^(x) 1, ^(y)1) and our second point,

(7,8) represents (^(x)2, ^(y)2).

So, plugging the given information into the formula, we have\sqrt{7 - (-1))^(2)  + (8 - 2)^(2)}.

Next, we simplify inside the parentheses to get\sqrt{(8)^(2)  + (6)^(2)}.

Next, 8² is 64 and 6² is 36 so we have √(64 + 36) or √(100) which is 10.

So the distance between the points (-1,2) and (7,8) is 10.

Answers

Answer:

(A) 3x^3+5x+2

Step-by-step explanation:

To Simplify:  The quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.

Solution: The given statement can be easily rewritten as:

The quantity 3 times x to the 4th power=3x^4,

5 times x to the 2nd power=5x^2 and

2 times x =2x

Thus, according to the statement, the expression can be written as:

(3x^4+5x^2+2x)/(x)

3x^3+5x+2

which is the required simplified expression.

Thus,option A is correct.

If ,f(x)=x^3-x what is the average rate of change of f(x) over the interval [1, 5]?a. 29.5
b. 30
c. 43
d. 120

Answers

Answer:

Option b is correct

30 is the average rate of change of f(x) over the interval [1, 5]

Step-by-step explanation:

Average rate of change (A(x)) of f(x) over interval [a, b] is given by:

A(x) = (f(b)-f(a))/(b-a)         ....[1]

As per the statement:

Given the function:

f(x) = x^3-x

We have to find the  average rate of change of f(x) over the interval [1, 5].

At x = 1

then;

f(1) = 1^3-1 =1-1 = 0

At x= 5

then;

f(1) = 5^3-5 =125-5 =120

Substitute these given values in [1] we have;

A(x) = (f(5)-f(1))/(5-1)

A(x) = (120-0)/(4)

A(x) = (120)/(4)=30

Therefore, the average rate of change of f(x) over the interval [1, 5] is, 30
