Use trigonometric expressions to build an equivalent trigonometric identity with the given expression: sec (x) tan (x) cos (x) c
Bess [88]

Answer:

sec (x)

Step-by-step explanation:

sec (x) tan (x) cos (x) csc (x) =

We know sec = 1/ cos

Tan = sin/cos

csc = 1/sin

Replacing into the expression

1/ cos (x) * sin(x)/ cos (x) * cos (x) * 1 / sin(x)

Canceling like terms

1/ cos (x)

sec(x)

Solve the quadratic equation 3x^2 + 2x - 4 = 0<br>Give your answers to 2 decimal places​
DochEvi [55]

Answer:

<h2>3x^2+2x−4=0</h2>

Use the quadratic formula to find the solutions

−b±√b^2−4(ac)/2a

Substitute the values

a=3, b=2, and c=−4 into the quadratic formula and solve for x.

−2±√2^2−4⋅(3⋅−4)/2⋅3

Simplify.

x = −1±√13/3

The final answer is the combination of both solutions.

x= −1−√13/3,−1+√13/3

The result can be shown in multiple forms.

Exact Form:

x= −1−√13/3,−1+√13/3

<h3>Decimal Form:</h3>

x=0.86851709…,−1.53518375…

Step-by-step explanation:

Emily is mowing her lawn which is in the shape of a rectangle with a length of 10 feet and width of 12 feet. Emily completed mow
docker41 [41]
So what you do first is find the area of this lawn and you do 10 by 12 and multiply those and you get 120 feet so now what you do is divived 120 by 3 and you get 40 so that means she mowed 40 ft in each hour so that would be the unit rate.
