Find the gradient of the line segment between the points<br> (-1,2) and (-2,3).

Svetach [21]

Answer:

The gradient of the line segment between the two points is -1

Step-by-step explanation:

The gradient of the line segment between two points is also known as the slope,

We can find this by using the formula; y₂ - y₁ / x₂ - x₁

The points given to us are;(-1,2) and (-2,3).

This implies x₁ = -1 , y₁=2 x₂ = -2 y₂= 3

We can now proceed to insert our values into the formula;

Gradient = y₂ - y₁ / x₂ - x₁

= 3 - 2 / -2-(-1)

= 1 / -2 + 1

=1/-1

Gradient = -1

Therefore the gradient of the line segment between the two points is -1

How to show the work for x4-y4

Juli2301 [7.4K]

I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)

In one jar, I have two balls labelled 1 and 2 respectively. In a second jar, I have three balls labelled 0, 1 and 2 respectively

PolarNik [594]

Step-by-step explanation:

this is a kind of trick question, actually.

with whatever we draw, we produce X values as power of 3.

to be precise, we can have only

3⁰ = 1

3¹ = 3

3² = 9

3⁴ = 81

due to the possible combinations of drawn numbers (e.g. 3 cannot be created by a multiplication of 0s, 1s and 2s).

so, mostly, these results cannot be exact factors of 1024.

1024 cannot be divided by 3, nor by 9 nor by 81.

but 1024 is a multiple of 1 (as is every number).

so, we are looking at the probability to get 0 as multiplication result of the numbers on the 2 drawn balls.

the only possibilities are

1 and 0

2 and 0

out of in total 6 (2×3) different outcomes

1 and 0

1 and 1

1 and 2

2 and 0

2 and 1

2 and 2

the probability of this "0" event is again

number of desired outcomes / number of possible outcomes = 2/6 = 1/3

Hi can someone please help me with this i will give you five stars!!

tino4ka555 [31]

Step-by-step explanation:

Let's look at what we know. We know that...

P=2000

r=0.04 (Change 4% to a decimal)

t=7 (25 years minus 18 years equals 7)

n=1

Since we are compounding each year, we need to use this equation: $P(1+\frac{r}{n} )^{nt}$

Now just plug the numbers in: (Answer to #1:) $2000(1+\frac{0.04}{1} )^{(1*7)}$

This equals 2631.86

When we round, this equals to $2,632. (Answer to #2).
