Answer:

D) no solution

Step-by-step explanation:

2x - 4y = 14

X + 2y = 7

2x - 4y + x + 2y = 14 + 7

2x - 4y + x + 2y = 21

3x - 2y = 21

no solution

Answer:

x=2y+7

step by step explanation:

2x-4y=14

2(x-2y)=14

x-2y=14/2

x-2y=7

x=2y+7

Which of the following options represents a logical first step that can be used
steposvetlana [31]

Answer: Option B.

Step-by-step explanation:

Here we can start with the relation

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

multiply both sides by cos(x)

cos(x) = cos(x)^3 + sin(x)^2*cos(x) = cos(x)^2*(cos(xI + sin(x)^2/cos(x))

now we can replace sin(x)/cos(x) = tg(x)

cos(x) = cos(x)^2*(cos(x) + sin(x)*tan(x))

So the correct option is B

In a billiards game, Pete hits a ball that is 20 in. from a wall. The ball travels 34 in. until it hits the wall and bounces to
Novosadov [1.4K]

Refer to the attached image,

Peter hits a ball that is 20 inch from a wall means AB=20 in

A ball travels 34 in until it hits the wall means AC=34 in

It bounces back to a position means CD = 'x' in (Say)

It bounces back to CD which is 16 in from the wall means DE=16 in

We have to calculate the value of 'x'.

Since, ball is reflected from point C. By law of reflection which states the angle of reflection is equal to the angle of incidence.

So, \angle ACF=\angle FCD = y degrees (say)

Since angles BCF and FCE are right angles.

So, \angle BCA=\angle DCE = 90-y^\circ (equation 1)

Now, in triangle ABC and CDE

\angle B=\angle E (Each angle is right angle)

\angle BCA=\angle DCE (From equation 1)

Therefore, triangle ABC is similar to triangle DEC by AA similarity.

So, the ratio of corresponding sides are equal.

\frac{AB}{DE}=\frac{AC}{DC}

Substituting the values,

\frac{20}{16}=\frac{34}{x}

20x = 544

x = 27.2 in

Therefore, the distance, x, the ball traveled after it bounced off the wall to get to the ending position is 27.2 in

What is the volume of the cone shown below?
andrezito [222]
<h3>Answer: Choice A) 1344π  cubic units</h3>

Work Shown:

r = 8 = radius

h = 63 = height

V = volume of the cone

V = \frac{1}{3}\pi*r^2*h\\\\V = \frac{1}{3}\pi*8^2*63\\\\V = \left(\frac{1}{3}*8^2*63\right)\pi\\\\V = \left(\frac{1}{3}*63*8^2\right)\pi\\\\V = \left(21*64\right)\pi\\\\V = 1344\pi\\\\

Side note: You could write the symbol π as "pi" without quotes.
