A ball rolling down the hill is an example of what type of energy

Answer:

The answer is "[tex]\bold{\theta= 70.53^{\circ}}[/tex]"

Step-by-step explanation:

The given value:

[tex]8x+8y+8z = 1\ and \ 8x-8y+8z = 1[/tex]  

When the normal vectors are in the plane:  

[tex]n_1 = < 8,8,8 > \ and \ n_2 = < 8, -8, 8>:[/tex]

Because the two variables really aren't proportional to each other and the wings are not parallel.  

Let us just find that two vectors' dot product.

[tex]n_1 \cdot n_2 =<8,8,8> < 8,—8,8>\\\\ = 64-64+ 64 \\\\ = 64 \neq 0[/tex]

Therefore, we won't find that angle between both the given planes as parallel.

[tex]\cos \theta = \frac{n_1 \cdot n_2}{|n_1||n_2|}\\\\\cos \theta =\frac{64}{\sqrt{192} \sqrt{192}}\\\\\cos \theta =\frac{64}{8\sqrt{3} 8\sqrt{3}}\\\\\cos \theta = \frac{1}{3}\\\\ \theta = 70.53^{\circ}[/tex]

It is required to know the orientation of one plane relative to the other.

The angle between the planes is 70.5°.

The given planes are

8x + 8y + 8z = 1

8x − 8y + 8z = 1

Parallel

[tex]\dfrac{8}{8}=\dfrac{8}{-8}=\dfrac{8}{8}\\\Rightarrow 1\neq -1\neq 1[/tex]

The planes are not parallel.

Perpendicular

[tex]8\times 8+8\times -8+8\times8=64\neq 0[/tex]

The planes are not perpendicular as dot product is not 0.

Finding angle

[tex]\theta=\cos^{-1}\dfrac{8\times 8+8\times -8+8\times8}{\sqrt{8^2+8^2+8^2}\sqrt{8^2+(-8)^2+8^2}}\\\Rightarrow \theta=\cos^{-1}\dfrac{1}{3}\\\Rightarrow \theta=70.53^{\circ}[/tex]

Answer:

Step-by-step explanation:

10 yards in 5 hours is 2 yards an hour

8*2=16 yards in 8 hours

Answer:

16 yards

Step-by-step explanation:

he would mow 2 yards an hour in 5 hours because 2 x 5 = 10 so if you use 2 it would be 16

Answer:   17.5 square yards

================================================

Work Shown:

base = 5 yards

height = 7 yards

The base and height are always perpendicular to one another

area of triangle = 0.5*(base)*(height)

area of triangle = 0.5*(5)*(7)

area of triangle = 17.5 square yards

The other values aren't used. They're likely thrown in as a distraction.

Answer:

The probability of all three children being girls will Be: 1/8

Step-by-step explanation:

The couple has 3 children.

We have to determine the probability of all three children being girls.

As we know that for each child, the probability of being a girl is ' [tex]\frac{1}{2}[/tex] ' as is the probability of being a boy is ' [tex]\frac{1}{2}[/tex] '.

so for there to be all girls, the probability will be:

P  ( all girls)  = 1/2 × 1/2 × 1/2 = 1/8      

Therefore, the probability of all three children being girls will Be: 1/8

Answer:

y = 2x + 4

Step-by-step explanation:

So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.

Answer:

Approximately 6.67 pancakes.

Step-by-step explanation:

We can write an equation that relates the two items.

Let P represent Pancake and let W represent Waffle.

Pancakes are worth 1.5 times a Waffle. Therefore:

[tex]W=1.5P[/tex]

To find the Pancake value for 10 Waffles, we can substitute 10 for W and solve for P. Therefore:

[tex]\begin{aligned} W&=1.5P \\ 10&=1.5P \\ 6.\overline{6}&=P \end{aligned}[/tex]

Hence, 10 Waffles equates to approximately 6.67 pancakes.

Answer:

The probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles is 0.151.

Step-by-step explanation:

The age groups and preferences are given as follows:

                                     18 - 24     25 - 34       35 - 55     55 and over      Total

Liked Crunchicles           39             66              10                  86                201

Disliked Crunchicles       27              19             38                  95                179

No Preference                 24             37             35                  24                120

Total                                 90           122             83                205               500

One consumer from the survey is selected at random.

Compute the probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles as follows:

[tex]P(18-24|DC)=\frac{P(18-24\cap DC)}{P(DC)}[/tex]

                        [tex]=\frac{n(18-24\cap DC)}{n(DC)}\\\\=\frac{27}{179}\\\\=0.15084\\\\\approx 0.151[/tex]

Thus, the probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles is 0.151.

Answer:

x = 85°, y = 30°

Step-by-step explanation:

40° + x + 55° = 180°

x + 95° = 180°

x = 85°

85° + 65° + y = 180°

150° + y = 180°

y = 30°
