Vladimir [108]3 years ago

5 0

Answer:

330

Step-by-step explanation:

We use formula n! /((n-r)!r!)

11!/((11-4)!4!)

11!/((7!)(4!))

11x10x9x8x7!/(7!)(4!)

11x10x9x8/(4!)

11x10x72/24

11x10x3

330

Therefore number of ways =330

Find the product. (z + 3i)(z − 3i)

Doss [256]

Answer:

First, we use distributive property:

$(z+3i)(z-3i)=z^2-3zi+3zi-9i^2$

Now, remember that $i^2=-1$ , then

$z^2-3zi+3zi-9i^2=z^2-9(-1)=z^2+9$

Then,

$(z+3i)(z-3i)=z^2+9$

Justin wants to place one of his 4 signed hockey sticks on his shelf. The length of the shelf is exactly 1.05 meters. His 4 hock

jolli1 [7]

Answer:

Stick 2

Step-by-step explanation:

Given

$L = 1.05m$ --- Shelf length

Missing information from the question are:

$Stick\ 1 = 1.4m$

$Stick\ 2 = 1.041m$

$Stick\ 3 = 1.14m$

$Stick\ 4 = 1.104m$

See attachment

Required

Which stick best fits the shelf?

The following observations are to be noted:

The length of stick 1 of 1.4m is greater than the length of the shelf

The length of stick 3 of 1.14m is greater than the length of the shelf

The length of stick 4 of 1.104m is greater than the length of the shelf

Only stick 2 (of length 1.041m) has a smaller length when compared to the length of the shelf.

Hence, Justin should choose stick 2

Answer:

a = 8 ÷ 1/8

Step-by-step explanation:

All I really did was put another variable similar to the x in the original problem, then I changed the numbers to be a bit lower while still keep the original work-- In a short term, I lowered the 9s to 8s.

Triangle abc is congruent to triangle xyz in abc ab 12

Kipish [7]

A triangle is a polygon with three edges and three vertices, perimeter of ΔABC = 36cm.

<h3>Congruent triangles are what?</h3>

Congruent triangles are two triangles that are identical in terms of their size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.

Triangles with equal measures are congruent.

36cm = perimeter of ΔABC

Here we have,

ΔABC ≅ Δ XYZ

So,

$= > 12 = XY = AB\\= > 14 = XZ = AC\\= > 10 = YZ = BC\\$

Therefore, perimeter of ΔABC = 36cm
