How would I find all the solutions to the equation "7*sin^2x-14*sinx+2=-5"?

Mathematics
1 answer:
Aneli [31]2 years ago

Answer:

Step-by-step explanation:

Find all solutions to the equation.

7 sin^2(x) - 14 sin x + 2 = -5

7sin^2(x)-14 sin x+7 =0

sin^2(x)-2sin x+1 =0

(sinx-1)(sinx-1)=0

sinx=1

x=π/2+2pi*k, k=integer

There are 45 male teachers and 75 female teachersin a school. Find the percentage of male teachers, female teachers in the schoo
Zielflug [23.3K]

Answer:

37.5% are male

62.5% are female

Step-by-step explanation:

in total 120 teachers (45 male+75 female)

therefore:

for male

120 - 100%

45 - x%  (we need to find x)

by using the butterfly method (or cross multiply) we get:

120x=100*45

x=4500/120=37.5% (male teachers)

we do the same for female but instead of using 45 we will use 75(the quantity of female theachers in school)

120x=100*75

x=7500/120=62.5%

Which shows the first step in the solution to the<br> equation log₂x + log₂(x - 6) = 4?
iren [92.7K]

log was used calculate big numbers before calculators

log is a re-arranged way to show a number with an exponent

example

log₂ 16 = 4 means 2^4 = 16

logx(Z) = y means x^y=Z

log(x-6)/log(2) + log(x)/log(2) = 4

(log(x-6)+ log(x))/log(2) = 4

(log(x-6)+ log(x)) = 4log(2)

(log(x-6)x) = log(16)

x=8
