Answer:

CB = 1.338r

Where r is the radius

Step-by-step explanation:

Angle ACB = 90 - 42 = 48

Angle at A = 180 - 2(48) = 84

CB² = r² + r² - 2(r)(r)cos(84)

CB² = 1.790943073r²

CB = 1.338r

Answer:

See below.

Step-by-step explanation:

Use the quadratic function f(x) = -x^2 - 6x. The parabola faces downward with y -intercept (-3,9) and zeros (-6,0) and (0,0). See the attached graph.

Tan tita = opp/adjacent

tan65 = x/3

tan 65 is 2.14

so...you are left with 2.14=x/3

by cross multiplying

x= 2.14 × 3

= 6.43

Answer:

the 19th term of the arithmetic sequence is 73.

Step-by-step explanation:

Given:

The arithmetic sequence whose common difference is

$d=4$

And first term is

$a=1$

Find the 19th term of the arithmetic sequence

$n=19$

Now we know that,

$a_{n}=a+(n-1)d$

Put all the value in above AP.

$a_{19}= 1+(19-1)4$

$a_{19}= 1+18\times 4$

$a_{19}= 1+72$

$a_{19}= 73$

So, $19_{th}$ term of the sequence is 73.
