Find the 91st term of the arithmetic sequence 28, 8, –12, ...<br><br> Anybody know the answer?
tankabanditka [31]

Answer:

-1772

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as;

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

From the sequence

a = 28

d = 8-28 = -12-8 = -20

n =91(since we are looking for the 91st term)

Substrate

T91 = 28+(91-1)(-20)

T91 = 28+90(-20)

T91 = 28-1800

T91 = -1772

Hence the 91st term is -1772

If a polynomial function f(x) has roots -9 and 7-i, what must be a factor of f(x)
Likurg_2 [28]

Hello from MrBillDoesMath!

Answer:

x + 9 and (x + ( i - 7)) are factors

Discussion:

If f(x) has roots -9 and 7-i then

f(x) = g(x)(x - (-9))  (x - (7-i))            ( g(x) is a polynomial of degree less than f(x))

That is, x + 9 and (x + ( i - 7)) are factors of f(x)

BTW: if the coefficients of f(x) are real (not stated in the Question) then the conjugate of 7-i, i.e. 7 + i, is  also be a root.

Thank you,

MrB

Calculate the angle of depression, x, if the boat is 750 ft. away from the light house and the light house is 300 ft high. Round
I am Lyosha [343]

Firstly , we need to draw diagram

we are given

opposite =300

adjacent =750

now, we can use tan formula

tan(x)=\frac{300}{750}

now, we can find x

x=tan^{-1}(\frac{300}{750})

we get

x=21.8  degree

so,

angle of depression is 21.8 degree.....Answer
