Simplify and write the trigonometric expression in terms of sine and cosine: sinx + cotx cosx=1/f(x)

Mathematics
1 answer:
Lemur [1.5K]3 years ago
3 0

Answer:

Step-by-step explanation:

cot(x)=cos(x)/sin(x)

sin(x) + cos(x) * cos(x)/sin(x) = 1/f(x)

(sin^2 + cos^(x))/sin(x) = 1 / f(x)

1 / sin(x) = 1 / f(x)

Taking the reciprocal of both sides, we get

sin(x) = f(x)

Courtney walks 1 mph slower than Brandi does. In the time that it takes Brandi to walk 6.5 mi, Courtney walks 5 mi. Find the spe
posledela

Answer:

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

Step-by-step explanation:

Let x = Courtney's walking speed

then

(x + 1) = Brandi's walking speed

:

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time

6.5/x + 1 = 5/x

Cross multiply

6.5x= 5(x+1)

6.5x= 5x + 5

6.5x - 5x = 5

1.5x = 5

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

Note that:

(x + 1) = Brandi's walking speed

3.33mph + 1 = 4.33mph

Therefore,

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

How do I factor 14x^2-7xy-147y^2
Viefleur [7K]

STEP 1

Equation at the end of step

((14 • (x2)) -  7xy) -  (3•72y2)  

Equation at the end of step 2

 ((2•7x2) -  7xy) -  (3•72y2)

STEP 3

STEP 4

Pulling out like terms

4.1     Pull out like factors :

  14x2 - 7xy - 147y2  =   7 • (2x2 - xy - 21y2)

Trying to factor a multi variable polynomial :

4.2    Factoring    2x2 - xy - 21y2

Try to factor this multi-variable trinomial using trial and error

Found a factorization  :  (2x - 7y)•(x + 3y)
