Use the law of cosines to find the missing length, which we'll call d:

d^2=100^2+120^2-2(100)(120)\cos 45^\circ

d^2=24400-12000\sqrt{2}

\boxed{d\approx 86\text{ cm}}.

What two numbers multiply to 30 and add to -17
victus00 [196]

Answer:

-15 and -2

Step-by-step explanation:

Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.

Negative Factors of 30:

-30 + -1 = -31

-15 + -2 = -17

-10 + -3 = -13

-6 + -5 = -11

The two factors of 30 that add up to -17 are -15 and -2.

Hope this helps. Have a nice day.

Find the 37th term of 352,345,338
Mariulka [41]

Answer:

a_{37}=100

Step-by-step explanation:

Given that,

A sequence 352,345,338.

First term = 352

Common difference = 345-352 = -7

We need to find the 37th term of the sequence.

The nth term of an AP is given by :

a_n=a+(n-1)d\\\\a_{37}=352+36\times (-7)\\\\a_{37}=100

So, the 37th term of the sequence is 100.
