Answers

Answer 1

Answer:

Find the multiples of each number:

18: 1 , 2 , 3 , 6 , 9 , 18

24: 1, 2, 3, 4, 6 , 8, 12, 24

Now find the matching numbers:

1 , 2, 3 , 6

What multiplies to make 12 and adds up to 16

Answers

To solve Q.15, remember to multiply the first numerical coefficient, in this case 3 to -12, to find the numbers to multiply and get that product. The middle term represents the sum the same two numbers must add to.

For example:

3r^2 - 16r - 7 = 5
3r^2 - 16r - 12 = 0

What 2 numbers multiply to give you -36, and add to give you -16, are -18 and +2, since -18 • 2 = -36, and -18 + 2 = -16.

3r^2 - 18r + 2r - 12 = 0
Factor
3r(r - 6) + 2(r - 6) = 0
(3r + 2)(r - 6) = 0
r = 6

3r + 2 = 0
3r = -2
r = -2/3.

Your 2 solutions for r are -2/3 and 6.

A 75.0 kg person steps on a scale in an elevator. The scale reads 761 N. What is the magnitude of the acceleration of the elevator?

Answers

You can use Newton's law, Resultant force=Mass×Acceleration.To find the acceleration take force over mass of the person which is 761N÷75.0kg.Hope this helps.

Find the slope of each line. 9) y = -x + 3 A. -1 B. 1 C. 3 D. -3

Answers

Answer: -1

Reason:

Compare the given equation to the template y = mx+b

m = -1 = slope

b = 3 = y intercept

If it helps, then think of y = -x+3 as y = -1x+3

Final answer:

The slope of the line represented by the equation y = -x + 3 is -1.

Explanation:

The question is asking you to find the slope of the line represented by the equation y = -x + 3. In the standard form of a linear equation, y = mx + b, m is the slope of the line. The slope of a line tells you how steep the line is. It is determined by the ratio of the vertical change (the 'rise') to the horizontal change (the 'run') between any two points on the line. In this case, the equation of the line is y = -x + 3, so the slope of the line is the coefficient of x, which is -1. Therefore, the correct answer is A, -1. This might contrast with the figure A1 example, in which m is 3, but for your particular equation, m is -1.

Finish the sequence

Answers

This is a Fibonacci sequence
1; 1
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
next terms:
5 + 8= 13
8 +13 = 21
13 + 21 = 34

The Fibonacci sequence has to be thought of in these terms:

F₀, F₁, F₂, F₃, F₄, F₅, F₆, F₇, etc, etc

----------------------

Now:

F₀=0

F₁=1

The formula you use to get the other numbers is:

$F_(n) = F_(n-1) + F_(n-2)$

--------------

So:

$F_(2) = F_(2-1) + F_(2-2) = F_(1) + F_(0) =1+0=1$

And:

$F_(3)= F_(3-1) + F_(3-2) = F_(2) + F_(1) =1+1=2$

------------

If you continue using the formula, you should get a sequence that starts off like this:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, etc, etc
