This one is common sense, not math. You can't possibly get a 5 and a green face on the same roll, because all of the odd numbers are red. Each condition rules out the other one. That's called being "mutually exclusive".

Is 2/3 greater than 2/4

Answers

2/3=0.666666666666........

1/2=0.500000000000........

Therefore:

2/3 > 1/2

The answer is yes because the fraction 2/3 is greater than 2/4.

Is 2/3 greater than 2/4?

To compare 2/3 and 2/4, we need to find a common denominator.

The least common multiple (LCM) of 3 and 4 is 12. So, we can rewrite the fractions with a common denominator:

2/3:

= (2/3) * (4/4)

= 8/12

2/4:

= (2/4) * (3/3)

= 6/12

Therefore, the answer is yes because the fraction 2/3 is greater than 2/4.

Answers

When you use a parameter to describe equations then you are talking about Parametric Equations, that is, you can write both $x$ and $y$ as functions of a parameter $t$ . In this problem we have the following equations:

$x=2-t \n y=x^(2)+1$

So substituting $x$ in $y$ we have:

$y=(2-t)^2+1 \n y=4-4t+t^2+1 \n y=t^2-4t+5$

So this equation represents a parabola where $y$ is the dependent variable and $t$ is the independent variable. This equation is shown in the figure below, the best statement that describes this curve is:

The curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t.

A curve is described by parametric equations x = 2 - t;

y = x^2 + 1 statement the curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t is the best-described curve.

We use a parameter to describe equations then we are talking about Parametric Equations, that isWe can write both as functions of a parameter.

We have given the parametric equation

$x = 2 - t\ny = x^2 + 1$

What is the parametric equation?

The parametric equation defines a group of quantities as functions of one or more independent variables called parameters.

So substituting the value of x in y we get,

$y=(2-t)^2+1\ny=2^2-4t+t^2+1\ny=4-4t+t^2+1\ny=5-4t+t^2\n$

So this equation represents a parabola where y is the dependent variable and t is the independent variable.

This equation is shown in the following figure, the best statement that describes the curve.

Therefore we can say that the curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t.

The factorization of 8x3 – 125 is (2x – 5)(jx2 + kx + 25). What are the values of j and k?

Answers

If you would like to find the values of j and k, you can do this using the following steps:

8x^3 - 125 = (2x - 5) * (jx^2 + kx + 25)
8x^3 - 125 = 2jx^3 + 2kx^2 + 50x - 5jx^2 - 5kx - 125

8x^3 = 2jx^3
4x^3 = jx^3
j = 4

2kx^2 + 50x - 5jx^2 - 5kx = 0
2kx^2 + 50x - 20x^2 - 5kx = 0
2kx^2 - 20x^2 + 50x - 5kx = 0
2kx - 20x + 50 - 5k = 0
2x(k - 10) = 5k - 50
2x(k - 10) = 5(k - 10)
k = 10

The correct result would be: j = 4 and k = 10.

j=4 k=10 on edg ;)
