Answer:

(s +1)²(s +5)

Step-by-step explanation:

Factors of the first denominator are ...

s² +2s +1 = (s +1)²

Factors of the second denominator are ...

s² +6s +5) = (s +1)(s +5)

The least common denominator will be the product of the unique factors to their highest power.

LCD = (s +1)²(s +5)

I find it most useful to leave the denominator in this form. Your computer may require it be multiplied out.

LCD = (s² +2s +1)(s +5) = s³ +2s² +s + 5s² +10s +5

LCD = s³ +7s² +11s +5

Toby goes on holiday to Geneva, Switzerland. In Geneva, Toby sees a watch costing 193.75 CHF (swiss france). In Manchester, an i

Answer:

Part a) In Geneva the watch is cheaper

Part b) The watch in Geneva is $\£20$ cheaper than the same watch in Manchester

Step-by-step explanation:

The question is

a) In which city is the watch cheaper?

b) By how much is it cheaper (in £)?

Part a)

Transform $CHF\ to\ \£$ in order to work with the same currency and make the comparison

If $\£1=1.55CHF$

$193.75\ CHF=193.75(\frac{1}{1.55})=\£125$

Now we can make the comparisons:

In Geneva the watch costs

$\£125$

and

in Manchester it costs

$\£145$

$\£125 < \£145$

therefore

In Geneva the watch is cheaper

Part b)

If we want to know by how much is cheaper, subtract from the expensive price the value of the cheaper price

$\£145-\£125=\£20$

Therefore

The watch in Geneva is $\£20$ cheaper than the same watch in Manchester

Answer:

Volume of sphere = 4.186 cubic inches

Step-by-step explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: $Volume\:of\:sphere=\frac{4}{3}\pi r^3$

Putting value of radius and π and finding volume:

$Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in$

So, Volume of sphere = 4.186 cubic inches
