h=opposite

7.01=adjacent

note:7.01 was gotten by 20-12.99

from \: sohcahtoa \\tan \alpha  =  \frac{ |o| }{|a|} \\ tan46 =   \frac{ |h| }{ |7.01| } \\  0.2086 =  \frac{  |h| }{ |7.01| }  \\ h = 0.2086 \times 7.01 \\ h = 1.462m

A polynomial function upper P left parenthesis x right parenthesis with rational coefficients has the given roots. Find two addi
mylen [45]

Given that a polynomial function P(x) has rational coefficients.

Two roots are already given which are i and 7+8i,

Now we have to find two additional roots of P(x)=0

Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.

conjugate of a+bi is given by a-bi

So using that logic, conjugate of i is i

also conjugate of 7+8i is 7-8i

Hence final answer for the remaining roots are (-i) and (7-8i).

There are 45 students in a class. The ratio of boys to girls is 2:3. How many boys are there in the class?
Lena [83]

Answer:

18 boys

2+3=5

Then we divide 45 by 5 because we want to find what 1 part equals"

45/5=9

We now do 9*2 to get an answer of:

9*2=18

hope this makes sense!

X^2+2x-5=0 quadratic form
julsineya [31]

Answer:

-1+√6

-1-√6

Step-by-step explanation:

x²+2x-5=0

x=(-2±√(2²-4(-5)))/2=(-2±√(4+20))/2=(-2±√24)/2

x₁=(-2+√24)/2 or x₂=(-2-√24)/2

x₁=(-2+2√6)/2 or (-2-2√6)/2

x₁=-1+√6 or x₂=-1-√6
