Find the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.

riadik2000 [5.3K]

<span>First of all to calculate the distance between two points we can use distance formula

d=Square Root [(x2-x1)^2 + (y2-y1)^2]

Now substitute the given points p(x1,y1) and q(x2,y2)in above distance formula

The values are X2=3, X1=8and Y2=8and Y1=2.

After Substituting the values

d=Square Root[(-5)^2+(6)^2]

d=Square Root(25+36]

d=Square Root[61]

d=7.8

7.8 is the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.</span>

PLEASE HELP THIS IS IMPORTANT DONT TROLL ME PLZ

MrRa [10]

Answer:

5 meters

Step-by-step explanation:

So Zane starts at -25 meters, then, after 35 seconds, he makes it to the top. The questions is asking how high he climbed every 7 seconds. As we know, 7x5 is equal to 35. this means that we can divide 35 and 25 by 5 to get the answer. 25/5 is equal to 5, so that means he climbed 5 meters every 7 seconds. I hope this helps!

Five is three more than a number n. <br> I don't understand this at all!

olga2289 [7]

So what they are telling you is that 5 is three higher than the variable n.
So n = 5-3
so n is 2.

Answer:

The answer is y=-x+9.

The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9

Which of the following statements is false?

kramer

Option D

The sum of two irrational numbers is always rational is false statement

<em><u>Solution:</u></em>

<h3><u>The sum of two rational numbers is always rational</u></h3>

"The sum of two rational numbers is rational."

So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.

For example:

$\frac{1}{4} + \frac{1}{5} = \frac{9}{20}$

rational number + rational number = rational number

Hence this statement is true

<h3><u>The product of a non zero rational number and an irrational number is always irrational</u></h3>

If you multiply any irrational number by the rational number zero, the result will be zero, which is rational.

Any other situation, however, of a rational times an irrational will be irrational.

A better statement would be: "The product of a non-zero rational number and an irrational number is irrational."

So this statement is correct

<h3><u>The product of two rational numbers is always rational</u></h3>

The product of two rational numbers is always rational.

A number is said to be a rational number if it is of the form p/q,where p and q are integers and q ≠ 0

Any integer is a rational number because it can be written in p/q form.

Hence it is clear that product of two rational numbers is always rational.

So this statement is correct

<h3><u>The sum of two irrational numbers is always rational</u></h3>

"The sum of two irrational numbers is SOMETIMES irrational."

The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational.

Thus this statement is false
