A ball is thrown from a height of 140 feet with an initial downward velocity of 8 ft/s. The ball's height h (in feet) after t seconds is given by the following.

h=140-8t-16t^2

Answer:

The amplitude of the function is 3, period of the function is [tex]\frac{\pi}{2}[/tex] and midline of the function is 2.

Step-by-step explanation:

The given function is

[tex]f(x)=3\cos(4x-\pi)+2[/tex]               .... (1)

The standard form of a Cosine function is

[tex]g(x)=a\cos(bx+c)+d[/tex]               ... (2)

where, a is amplitude, period is [tex]\frac{2\pi}{b}[/tex] and d is midline.

From (1) and (2), we get

[tex]a=3,b=4,d=2[/tex]

The amplitude of the function is

[tex]a=3[/tex]

The period of the function is

[tex]\frac{2\pi}{b}=\frac{2\pi}{4}=\frac{\pi}{2}[/tex]

The midline of the function is

[tex]d=2[/tex]

Therefore the amplitude of the function is 3, period of the function is [tex]\frac{\pi}{2}[/tex] and midline of the function is 2.

The correct answer to fill in the blank is:

“Cognitive flexibility”

Cognitive flexibility refers to a person’s ability to adapt the mental processing strategies to face new and unexpected situations or problems. In this case, some of the students who initially did not solve the problem transformed their way of solving the puzzle after the discussion thus getting it right the next time.

Answer:

Option C is correct.

The missing steps in this proof is; [tex]\angle 1 \cong \angle 4[/tex] and [tex]\angle 3 \cong \angle 5[/tex].

Explanation:         

Given ΔABC.

Prove that:  The sum of the interior angle measures of ΔABC is [tex]180^{\circ}[/tex]

Let A ,B and C forms a triangle    [Given]

Parallel lines are those two lines that are always the same distance apart and never touch.

then, by the definition of parallel lines and labeling angles

DE be the line passing through B, parallel to AC, with angles as labelled in the figure as shown below in the attachment.

Alternative Interior Angle theorem states that the angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles also this theorem says that when the lines are parallel, then the alternate interior angles are equal.

Then,

[tex]\angle 1 \cong \angle 4[/tex] and                              

[tex]\angle 3 \cong \angle 5[/tex]        [By Alternative Interior angle theorem]            

Angles are always congruent if their measures in degrees are equal.

therefore,

[tex]m\angle 1 =m\angle 4[/tex] and

[tex]m\angle 3=m\angle 5[/tex]      [By Congruent Angle have equal measure]                                                                   ......[1]

Straight Angles states that angles on one side of a straight line always add to 180 degrees.

From the given figure;

By the addition angle and definition of straight angle we get;

[tex]m\angle 4 +m\angle 2 +m\angle 5 =180^{\circ}[/tex]      ......[2]

Substituting equation [1] in [2] we get;

[tex]m\angle 1 +m\angle 2 +m\angle 3 =180^{\circ}[/tex]  

Therefore, the sum of the interior angles measures of triangle ABC is [tex]180^{\circ}[/tex]

add them together:

124 + 88 + 62 +137 +195 = $606 total

Answer:  Option 'd' is correct.

Step-by-step explanation:

Since we have given that

[tex]f(x) = x^2[/tex]

We need to shift the function f(x) 3 units to the right to obtain the graph of g(x).

As we  know that shifting right is the horizontal shift.

And f(x-h) = g(x) , here f shift right h units.

so, After shifting 3 units right, we get that

[tex]g(x)=(x-3)^2[/tex]

Hence, Option 'd' is correct.

In the given diagram, the points that are shown to be collinear are H and E.

Collinearity in geometry refers to the condition where three or more points lie on the same straight line. In this case, points H and E are collinear as they lie on the same straight line, which is represented by a vertical double-headed arrow passing through them.

The diagram consists of two parallelograms, labeled 'I M' and 'E P', with three points inside each. In the parallelogram 'I M', the points are labeled as I, H, and J from top to bottom. Similarly, in the parallelogram 'E P', the points are labeled as F, E, and G from top to bottom. Among these points, only H and E share the same straight line, making them collinear. The other points do not share this line and hence are not collinear with H and E. This concept is fundamental in understanding geometric relationships and properties.

Answer:

b

Step-by-step explanation:

Answer:

Step-by-step explanation:

6^2 + 3^2 = x^2

36 + 9 = x^2

45=X^2

X= sqrt(45) = 3squareroot5

 answer is A

In the equation 50t + 3w = 150, 3w represents the distance Jennifer travels by walking in 3 hours.

In the equation 50t + 3w = 150, the term 3w represents the distance Jennifer travels by walking. Since w represents the number of hours she spends walking, 3w represents the distance she walks in 3 hours. This is because the rate of walking is constant, so if Jennifer walks for 1 hour and covers a certain distance, she would walk 3 times that distance in 3 hours.

In this case, since the run times are the one being compared and recorded, therefore the data being measured in the experiment is the run times.

The difference of the two groups of mice is the time of the day that the mice run, day or night. Therefore the variable being manipulated is the time of the day.

Final answer:

When solving math problems with rules of exponents, it is important to understand key concepts such as multiplication of exponentials, taking square roots of exponentials, and dividing exponentials.

Explanation:

When solving math problems with rules of exponents, there are several key concepts to keep in mind:

It is important to understand these rules and practice applying them to various problems in order to master solving math problems with rules of exponents.
