Answer:

Step-by-step explanation:

A)(tanx-4)(9sin^2x-1)=0\\\\\\

9sin^2x-1=0\\\\sin^2x=\frac{1}{9} sinx=\frac{1}{3} or sinx=\frac{-1}{3}

OR    tanx=4\\

B)

3sin2x=3.2.sinx.cosx\\\\6.sinx.cosx-4.sinx= 2sinx.(3cosx-2)=0\\\\3.cosx=2 cosx=\frac{2}{3}

Given : A mountain path is 12.1 miles long.

a hiker walks along the path at a rate of 1.96 miles per hour

To Find: in approximate how many hours will the hiker walk the entre trail

Solution:

Distance = 12. 1 miles

Speed = 1.96 mile/hr

Distance = Speed * time

12.1 = 1.96 * t

=> t = 12.1/1.96

=> t = 6.17

=> t ≈ 6 hrs 10 mins

Lines f and g are parallel which statement can you not reduce from this information?
liberstina [14]
Answer: Choice C

There is no way to figure out if angle 4 and angle 7 are congruent. If we knew they were right angles, then we would be able to determine that. However, that isn't the case here.

What is a necessary step for constructing perpendicular lines through a point off the line?
mixas84 [53]

Draw arcs on either side of a given point on the line

To construct a line perpendicular to another line through a point on the line:

Measure a length from that point to one edge of the line

Draw two intersecting arcs on either sides of the line

Draw a straight line from the intersecting point of the arcs to the point on the existing line.

The new line drawn is a perpendicular line.

The only step necessary out of the given choices is "Draw arcs on either side of a given point on the line"

Option C is the correct choice

Please read "Step-by-step" if you're having trouble

Answer:

x²(1-\frac{1}{4}\pi)

Step-by-step explanation:

Each side of the cookie dough is x long, since there is no given number, the diameter of the plate is also x, its as long as the square is wide, making the radius 1/2x.

The area of the cookie dough is x², the area of the plate is 1/4\pix².

You have the equation x²- \frac{1}{4}\pix²the equation has a Greatest Common Factor of x² so your factored equation is x²(1-\frac{1}{4}\pi)
