In the figure, BC is a support for the roof<br> of a garage. What is the length of BC?
Sonbull [250]

Answer:

Bc = √63 ft

Step-by-step explanation:

Here, we want to get the length of BC

As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side

So we want to get the third leg which is BC

we can use the Pythagoras’ theorem here

And that states that the square of the hypotenuse equals the sum of the squares of the two other sides

let the missing length be x

12^2 = x^2 + 9^2

144 = x^2 + 81

x^2 = 144-81

x^2 = 63

x = √63 ft

Use the iterative rule to find the 11th term in the sequence.
dolphi86 [110]

Answer:

-4

Step-by-step explanation:

The general, nth term, of a sequence is given by the formula:

a_n=18-2n

We can plug in n = 1 to find the first term, thus we have:

a_1=18-2(1)\\a_1=16

We can plug in n = 2, to the find the 2nd term, which is:

a_2=18-2(2)\\a_2=14

Similarly, to get 11th term, we simply plug in n = 11 into the general term rule. so we have:

a_n=18-2n\\a_{11}=18-2(11)\\a_{11}=18-22\\a_{11}=-4

11th term is -4
