The sum of the interior angles of a polygon is.

Sum = 180(n-2) where n is the number of sides

Thus 180(n-2) = 3780

n-2=3780/180 =21

⇒ n = 21+2 = 23

number of sides is 23

Sum of interior angles of n sided polygon = (n - 2) * 180

(n - 2) 180 = 3780

180n - 360 = 3780

180n =  4140

n = 4140 / 180  = 23 sides  Answer

Colin pays £766.45 a year on his car insurance.
aliina [53]

Answer:

£807.84

Step-by-step explanation:

Cost of Collins car insurance per year = £766.45

Percentage increase in price = 5.4%

How much does the insurance cost now?

Cost of the insurance now = £766.45 + 5.4% of £766.45

= 766.45 + 5.4/100(766.45)

= 766.45 + 0.054(766.45)

= 766.45 + 41.3883

= 807.8383

Cost of the insurance now = £807.84

Can anyone help me refresh my mind?!
Nuetrik [128]
That is correct. The log3 stays the same and the numerator goes first and then the denominator goes second. When it’s a fraction like that one, the standard form would be subtraction.

If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(–2)?
Vedmedyk [2.9K]
F(x) = 8 - 10x

g(x) = 5x + 4

Finding (fg)(-2).

First let us find fg(x),  this is the same as f(g(x))

f(g(x))

f(5x + 4)

Recall, f(x) = 8 - 10x, therefore f(5x + 4) would be such that anywhere we see x in the f(x), we replace it with 5x + 4

f(x) = 8 - 10x

f(5x +4) =  8 - 10(5x + 4)

             =  8 - 50x - 40

             = -50x + 8 - 40

             =  -50x - 32

f(g(x)) = fg(x) = -50x - 32

fg(-2) = -50*(-2) - 32 = 100 - 32 = 68

Therefore fg(-2) = 68

I hope this helped.
