\bf \cfrac{10!}{4!(10-4)!}\implies \cfrac{10!}{4!(6)!}\implies \cfrac{10\cdot 9\cdot 8\cdot 7\cdot \underline{6!}}{4!\underline{6!}}\implies \cfrac{10\cdot 9\cdot 8\cdot 7}{4!} \\\\\\ \cfrac{5040}{24}\implies 210

Help me idk how to do this
ElenaW [278]
To do this, you have to plug each x value into the rule.

1.y = 15 - 3×2
y = 15 - 6
y = 9

So the first y value would be 9.

2.y = 15 - 3×3
y = 15 - 9
y = 6

3. y = 15 - 3×4
y = 15-12
y = 3

4. y = 15 - 3×5
y = 15-15
y = 0

Hope this helps!

THE QUESTION IS DOWN BELOW.<br>major points when given branliest
emmainna [20.7K]

The ratios are Surface area ⇒ 4 : 25 Height ⇒ 2 : 5 and Volume ⇒ 8 : 125

<h3>How to determine the ratios?</h3>

The scale factor is given as:

m : n = 2 : 5

For the area, we take the square of the ratios.

i.e.

Area = 2^2 : 5^2

Evaluate

Area = 4 : 25

For the volume, we take the cube of the ratios.

i.e.

Volume = 2^3 : 5^3

Evaluate

Volume = 8 : 125

The given scale factor can be used for the height of the model and the original bicycle

Hence, the ratios are

Surface area ⇒ 4 : 25

Height ⇒ 2 : 5

Volume ⇒ 8 : 125
