Answer:

7xy

Step-by-step explanation:

Let's go by parts

The product of two numbers

Multiplied by 7

The product of two numbers, since we don't know what are they we can called them x and y so the product means the multiplication

$x*y=xy$

next xy has to be multiplied by 7

$7*xy=7xy$

so 7xy is our answer

Answer:

7(x times y)

Step-by-step explanation:

Product means multiply, so it wants you to multiply two numbers and multiply THAT by 7. So we will use two variables, in this case, I will use x and y. X times y. 7 Times that.

Triangle PQR has vertices at the following coordinates: P(0, 1), Q(3, 2), and R(5, -4). Determine whether or not triangle PQR is

ruslelena [56]

$PQ = \sqrt{(3-0)^2+(2-1)^2}= \sqrt{9+1}= \sqrt{10} \\ QR= \sqrt{(5-3)^2+(-4-2)^2}= \sqrt{4+36}= \sqrt{40} \\PR= \sqrt{(5-0)^2+(-4-1)^2}= \sqrt{25+25}= \sqrt{50}$

PR is the longest side.
The triangle will be right if
PQ² + QR² = PR²

PQ² + QR² = (√10)² + (√40)² = 10 + 40 = 50
PR² = (√50)² = 50
50=50 so, ΔPQR is a right triangle.

u and v are position vectors with terminal points at (-1, 5) and (2, 7), respectively. Find the terminal point of -2u + v.

kenny6666 [7]

<h3>Answer: (4, -3)</h3>

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

Work Shown

We'll be using these vector properties

Rule 1: (a,b) + (c,d) = (a+c, b+d)
Rule 2: k*(a,b) = (k*a, k*b)

To get the following

-2u + v = -2*(-1, 5) + (2,7)

-2u + v = (-2*(-1), -2*5) + (2,7) .... apply rule 2

-2u + v = (2, -10) + (2, 7)

-2u + v = (2+2, -10+7) .... use rule 1

-2u + v = (4, -3)
