Answer:

A. Learned behaviors.

Step-by-step explanation:

The two terms on the left side both have a common factor of (sin(α) + cos(β)), so we can pull it out like so:

(sin(α) + cos(β))² + (cos(β) + sin(α)) (cos(β) - sin(α))

= (sin(α) + cos(β)) [(sin(α) + cos(β)) + (cos(β) - sin(α))]

= (sin(α) + cos(β)) (sin(α) + cos(β) + cos(β) - sin(α))

= 2 cos(β) (sin(α) + cos(β))

Natural numbers are integers greater than 0 and not including it.

Lets list the natural numbers until 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Now, set C contains all of the natural numbers less than 7, so we select all of the numbers before 7 into our set.

You need 2 formulas to solve this. Use perimeter first and then area.

Formulas

P = 4s

Area = s^2

Givens

Perimeter = 24 feet

Solution

P = 4*s                   Substitute the value for P

24 feet = 4s           Divide both sides by 4

24/4 = 4s/4

6 = s

Now use the area formula

Area = s^2             Substitute 6 for s

Area = 6^2

Area = 36 feet^2

Answer

Area = 36 ft^2

The perimeter of a square is 24 feet. What is the area in square feet.

In this question we are provided with the perimeter of the square and we are asked to calculate the area of the square. First we will calculate the side of the square and then we will calculate the area.

[tex] \small{ \underline{ \underline{ \red{\rm{ Calculating \: the \: side \: of \: the \: square}}}}}[/tex]

We know,

[tex] \star \: \small\boxed{ \rm{ Perimeter_{(square)} = 4 × side}}[/tex]

Substituting the values we get

[tex] \small\bf 24 = 4 × s[/tex]

[tex] \small\sf{ → \dfrac{24}{4} = s}[/tex]

[tex] \small\sf{ → s = 6 \: feet}[/tex]

[tex] \small{ \underline{ \underline{\rm \red{ Now, we \: will \: calculate \: the \: area }}}}[/tex]

We know,

[tex] \star \: \small \boxed{{\rm Area_{(square)} = side × side}}[/tex]

Substituting the values we get

[tex] \small\rm {Area_{(square)} = (6 × 6) feet² = 36 \: feet²}[/tex]

Hence, the area of the square is 36 feet².

Using the relation between velocity, distance and time, it is found that the velocity of the helicopter is of 225 mph and of the wind is of 69 mph.

Velocity is given by distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

A helicopter took 39 minutes to fly 191 miles, traveling in a headwind. Due to the headwind, the relative velocity is the sum of the velocities, hence:

[tex]v_h + v_w = \frac{191}{\frac{39}{60}}[/tex]

[tex]v_h + v_w = 294[/tex]

[tex]v_w = 294 - v_h[/tex]

The same helicopter took one hour and 15 minutes to fly 195 miles flying in the opposite direction, hence:

[tex]v_h - v_w = \frac{195}{\frac{75}{60}}[/tex]

[tex]v_h - v_w = 156[/tex]

Since [tex]v_w = 294 - v_h[/tex]:

[tex]v_h - 294 + v_h = 156[/tex]

[tex]2v_h = 450[/tex]

[tex]v_h = 225[/tex]

[tex]v_w = 294 - 225 = 69[/tex]

Answer:

mean = 34

Step-by-step explanation:

the mean is calculated as

mean = [tex]\frac{sum}{count}[/tex] = [tex]\frac{20+28+30+38+39+40+43}{7}[/tex] = [tex]\frac{238}{7}[/tex] = 34

Answer: 34

Step-by-step explanation:

Mean is the same as average, and to find average you add all the numbers up and divide by the amount of numbers present. So, if you add all of them up, you get 238. Then, you'll divide by 7, since there are 7 numbers. And that will get you 34.

Answer:

The probability is 1/9

Step-by-step explanation:

1/3 x 1/3 = 1/9

Reason:

The probability of selecting "7" is 1/3 because there's one card labeled "7" out of three cards total.

The same applies to selecting a "5" as well. When the first card is put back, effectively nothing has changed.

The probability of getting a "7", then getting a "5" is (1/3)*(1/3) = 1/9

Answer:

a) angle QRP is 92 degrees, side QR is 23 cm, angle RPQ is 47 degrees

b) angle EFD is 65 degrees, side FD is 22cm, side ED is 20cm

Step-by-step explanation:

a) in the first example, you know that u are given QR, PR, and angle PRQ, and u are asked to find triangle PQR,or the rest of the lengths.

step 1-u draw an example of the triangle, i will provide one for each at the bottom of this answer

step 2-lets find the sides first with the pythagorean theorem, which will mean 25²+x²=34². Pythagorean theorem is a²+b²=c²

step 3-after solving for x, x will be 23.04, which means the third side is 23 cm (after rounding).

step 4-now that we have all the sides, we can solve for the rest of the angles, by trigonometric ratios, we are gonna use sine for angle RPQ, sine is sin(the angle u want to find)=opposite side/hypotenuse.

step 5- so sin(RPQ)=25/34, and solve for RPQ on a calculator (i used math) and angle RPQ will equal 47.3 degrees.

step 6- just subtract the sum of both angles from 180 an the last angle will be 92 degrees.

b) u are given the measure of angles FED and EDF and the side length FE, we will solve for the last angle first then we will go for the side engths

step 1- we subtract the sum of the two angles we have from 180 and we will get the measure of angle EFD to be 65 degrees, now we have the angles and we want to find he sides.

step 2-we use sine of angle 31 degrees to find the hypotenuse, but it is opposite of sine since we want to find the side, not the angle, so we will use sin(31)=11.3/x, the sine equation is written like sin(the angle u have)=opposite/hypotenuse.

step 3- after solving for arc sine in a calculator, u will find side FD to be 22cm, and now to find the last side.

step 4-i will use the sine of angle 65 degrees to solve for side ED, it will be sin(65)=x/22, which will make side ED equal 20 cm in length.

ur welcome :)

The rod would not be accepted If the diameter measurement will be less than 1.495. Then the correct option is A.

The compliance zone of the rod goes over the specification limits of the hole in Imperfect Fit. This indicates that the shaft is big, but the opening is little.

The diameter of a rod is required to be 1.51 inches with an acceptable variance of .015 inches.

The rod would not be accepted If the diameter measurement will be less than 1.495.

Upper limit

→ 1.51 + 0.015

→ 1.525

Lower limit

→ 1.51 - 0.015

0.5lb cereal squares, 0.75 lb nuts

Step-by-step explanation:

1lb nuts = $7

multiply each side by 1/2 (whatever you do to one side, you do to the other),

0.5lb nuts = $3.5

1lb cereal squares = $4

multiply each side by 3/4 (whatever you do to one side, you do to the other),

0.75lb cereal squares = $3

0.5lb nuts + 0.75lb cereal squares = 3.5 + 3 = $6.5
