Answer:

Step by Step explanation:

So since the equation says that 8 is less than the square root for b, It is correct because the square root of 72 would be 8.48528137424. Which of course 8, is less than that. But it also says that the square root of 72 is less than 9. Which based on my calculations would be correct.

Determine if each statement is true or false. If the statement is false, explain why, or show work proving that it is false.

kherson [118]

Answer:

a). true

b). true

Step-by-step explanation:

a).

Given : If a = 5, then ac = 5c

Let c be any constant.

a = 5 (given)

Therefore, ac = 5c

Here a is given a constant value (5), also let assume c to be a constant. So when we multiply each term we will get a constant value of 5c. The ratio does not change.

Hence proved.

b).

Given : If ac = 5c, then a = 5

Let c be any constant

It is given, a = 5

Therefore, ac = 5c

Here the product of two terms is given as 5c, where c is assume to be a constant. Then as a product rule, the value of a will be 5. The ratio will not change.

Hence proved.

Need help with this please.

Answer:

$y = -\frac{3}{2} x + 4$

Step-by-step explanation:

First, let us find the gradient of AB:

Gradient of AB = $\frac{-1-3}{-1-5}$

= $\frac{2}{3}$

We also need to know that The product of gradients which are perpendicular to each other is -1. Using this idea, we can find the gradient of the perpendicular bisector:

(Gradient of perpendicular bisector)( $\frac{2}{3}$ ) = -1

Gradient of perpendicular bisector = $-\frac{3}{2}$

Now, we need to know at which coordinates the perpendicular bisector intersects AB. A perpendicular bisector bisects a line to two equal parts. Hence the coordinates of the intersection point is the midpoint of AB. Thus,

Coordinates of intersection = ( $\frac{-1 + 5}{2}$ , $\frac{-1 + 3}{2}$ )

= ( 2, 1 )

Now, we can construct our equation. The equation of a line can be formed using the formula $(y - y_{1}) = m(x - x_{1})$ where $m$ is the gradient and the line passes through $(x_{1} , y_{1} )$ . Hence by substituting the values, we get:

$(y - 1) = -\frac{3}{2} (x - 2)$

$y - 1 = -\frac{3}{2} x + 3$

$y = -\frac{3}{2} x + 4$

The students in Mrs. Mandel’s class need to choose two class

sammy [17]

Do you know the Combination Formula? If Not it is (n!)/r!(n - r)!
I think n would equal 6, and r would equal 2. So it would be 6!/2!(4!)
I believe you can do this yourself now that I've given you an equation.
