Answer:

D. (7, 0)

Step-by-step explanation:

The rule for a reflection over the y-axis is (x, y) → (x, -y)

This means that the x-values stay the same while the y-values change.

Q(x, y) → (x, -y)

Q(3, 0) → (3, 0)

Q'(3, 0)

P(x, y) → (x, -y)

P(5, 6) → (5, -6)

P'(5, -6)

R(x, y) → (x, -y)

R(7, 0) → (7, 0)

R'(7, 0)

Therefore, the correct answer is D.

Answer:

B) 24

Step-by-step explanation:

distance = 6 km

we want the speed in km/h, so let's turn everything into either km or h if possible

time = 7:45 am - 7: 30 am = 15 minutes

60 minutes = 1 hour

1 hour / 60 minutes = 1

15 minutes * 1 = 15 minutes * 1 hour/60 minutes = 15 / 60 hours = 1/4 hours = 0.25 hours

note that we multiply by 1 hour / 60 minutes, not 60 minutes/ 1 hour. this is because we want the minutes to cross out -- because the original is given in minutes ( 15 minutes = 15 minutes/1) and is in the numerator, we need minutes in the denominator of 1 hour/60 minutes to cross it out

km = 6

h = 0.25

km/h = 6/0.25 = 24

Option D is correct. The number of team members who prefer tacos is the same as the combined number of team members who prefer hamburgers or pizza.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

Coach Rodriguez is planning an end-of-season celebration for the swim team.

To decide what food to serve, she surveys a random sample of students on the team Food for End-of-Season Celebration.

We can see that,

The number of team members who prefer tacos = 12

The combined a number of team members who prefer hamburgers or pizza = 7 + 5

         = 12.

So, The number of team members who prefer tacos is the same as the combined number of team members who prefer hamburgers or pizza.

The inference supported by the data collected in the survey would be option D.

Answer:

I think it's easiest to count the ways that they can consecutively sit together and subtract this from the total number of seating arrangements.

There are 6 groups of 3 consecutive seats.  Within each group there are 3!=6 ways the three people can be arranged

Then the remaining 5 people can be arranged 5!=120 ways in the remaining seats.

So there are 6*6*120 = 4320 arrangements where they DO sit consecutively

There are 8! = 40320 total arrangements.

So there are 40320 - 4320 = 36000 arrangements where the 3 do not sit consecutively.

Step-by-step explanation:

The value of sin D,  sin E , cos D , and cos E in simplest fraction form are as follows:

Sin D = 4 / 5

sin E = 3 / 5

cos D = 3  / 5

cos E = 4 / 5

The simplest trigonometric ratios expression are as follows:

Therefore,

Sin D = opposite / hypotenuse = 12 / 15 = 4 / 5

sin E = opposite / hypotenuse = 9  / 15 = 3 / 5

cos D = adjacent / hypotenuse = 9 / 15 = 3  / 5

cos E = adjacent / hypotenuse = 12 / 15 = 4 / 5

(h-10)² + r² = 10²                                   [insert values]

r² = 10² - (h-10)²                                     [change sides]

Step-by-step explanation:

A right triangle can be drawn with vertices at the center O, the base angle of the cone and the center of the base of the cone (see annotated image).

Side lengths of the formed right triangle:

Using Pythagoras' Theorem [tex]a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)

[tex]\implies r^2+(h-10)^2=10^2[/tex]

[tex]\implies r^2+h^2-20h+100=100[/tex]

[tex]\implies r^2+h^2-20h=0[/tex]

[tex]\implies r^2=20h-h^2[/tex]

[tex]\textsf{Volume of a cone}=\dfrac13 \pi r^2h[/tex]
(where r is the radius and h is the height)

Substitute the expression for [tex]r^2[/tex] found in part (a) into the equation so that volume (V) is expressed in terms of h:

[tex]\begin{aligned}V & =\dfrac13 \pi r^2h\\\\ \implies V & =\dfrac13 \pi (20h-h^2)h\\\\ & = \dfrac13 \pi (20h^2-h^3)\\\\ & = \dfrac{20}{3} \pi h^2-\dfrac13 \pi h^3 \end{aligned}[/tex]

To find the value of h such that the volume of the cone is a maximum, differentiate V with respect to h:

[tex]\begin{aligned}V & =\dfrac{20}{3} \pi h^2-\dfrac13 \pi h^3\\\\ \implies \dfrac{dV}{dh} & =2 \cdot \dfrac{20}{3} \pi h-3 \cdot \dfrac13 \pi h^2\\\\ & = \dfrac{40}{3} \pi h- \pi h^2\\\\ & = \pi h\left(\dfrac{40}{3}-h\right)\end{aligned}[/tex]

Set it to zero:

[tex]\begin{aligned}\dfrac{dV}{dh} & =0\\\\ \implies \pi h\left(\dfrac{40}{3}-h\right) & = 0\end{aligned}[/tex]

Solve for h:

[tex]\begin{aligned} \pi h & = 0 \implies h=0\\ \dfrac{40}{3}-h & =0\implies h=\dfrac{40}{3}\end{aligned}[/tex]

Substitute the found values of h into the equation for Volume:

[tex]\begin{aligned}\textsf{when}\:h=0:V &=\dfrac{20}{3} \pi (0)^2-\dfrac13 \pi (0)^3\\\\ \implies V & =0\sf \:cm^3\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{when}\:h=\dfrac{40}{3}:V &=\dfrac{20}{3} \pi \left(\dfrac{40}{3}\right)^2-\dfrac13 \pi \left(\dfrac{40}{3}\right)^3\\\\ \implies V & =\dfrac{32000}{27} \pi -\dfrac{64000}{81} \pi\\\\ & = \dfrac{32000}{81} \pi \\\\ & = 1241.123024..\sf \:cm^3\end{aligned}[/tex]

Answer: 73

Step-by-step explanation:

Angle B is 180-107=73

Angle 1 is equivalent to B and it is 73

Answer:

C.  ∠1 = 73°

Step-by-step explanation:

Angles on a straight line add up to 180°

Therefore:

⇒ ∠1 + 107° = 180°

Subtract 107° from both sides:

⇒ ∠1 + 107° - 107° = 180° - 107°

⇒ ∠1 = 73°

Considering the hypotheses tested, it is found that the p-value for Nicolas's test is of 0.101.

At the null hypotheses, it is tested if the mean is of 24, that is:

[tex]H_0: \mu = 24[/tex]

At the alternative hypotheses, it is tested if it is different, hence:

[tex]H_1: \mu \neq 24[/tex]

As we are testing if the mean is different of a value, we have a two-tailed test, with t = -1.79 and 12 - 1 = 11 df. Hence, using a t-distribution calculator, the p-value is of 0.101.
