Answer:

2.25 seconds

87 feet

[6, 87]

Step-by-step explanation:

The height of a projectile is:

h(t) = -16t² + vt + s

where v is the initial vertical velocity and s is the initial height.

Here, v = 72 and s = 6.

h(t) = -16t² + 72t + 6

This is a downwards parabola.  The maximum is at the vertex.

t = -b / (2a)

t = -72 / (2×-16)

t = 2.25

h(2.25) = 87

It takes 2.25 seconds to reach the maximum height of 87 feet.

The range is from the lowest height (6 feet) to the maximum height (87 feet).  In interval notation:

[6, 87]

Final answer:

This response explains the time to reach maximum height, calculates the maximum height, and determines the range function for the projectile motion of the T-shirt launched by a slingshot during halftime at a football game.

Explanation:

Maximum Height Calculation:

Time to Reach Maximum Height: 2.25 seconds

Maximum Height: 81 feet

Range Function: The range function (horizontal distance) can be determined using the formula: R = V₀t, where V₀ is the initial velocity and t is the time taken to reach the maximum height.

Answer:

the answer is b

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

The law of detachment says that, given to facts A and B:

if A ---> B (this is, if that fact that A happens make that B happens) and A is true (This is, A happens), so B will happen.

In this case let A be "Jillian gets a rise" and B "Jillian buys a car". A ---> B  means what the statement says "If Jillian gets a raise, then she will buy a new car". Here, the law of Detachment implies that if A happens, i.e., if Jillian gets a rise she would surely buy a new car. As she got her rise (the last sentence on the statement) so she WILL buy a new car.

You have to keep in mind that we can not make inference in the contrary sense. If you observe that Jillian bought a new car you can not say that she got a rise. The inverse sense does not work here, it is only in one direction, from A to B.

Step-by-step explanation:

PROPORTIONALITY:

Two quantities x and y are said to proportional to each other

if for x ∝ y , x = y k.

Here, k i s called the PROPORTIONALITY CONSTANT.

⇒  [tex]x \propto y \implies  k = \frac{x}{y}[/tex]

Now, for the given quantities:

a.  $18.36 for 3 pizzas [box]    

Here,[tex]k =  \frac{18.36}{3} = 6.12[/tex]

So, the proportionality constant is 6.12.

b. $4.17 for 3 pounds of bananas [box]

Here,[tex]k =  \frac{4.17}{3} = 1.39[/tex]

So, the proportionality constant is 1.39.

c. $16.48 for 4 pounds of potatoes [box]

Here,[tex]k =  \frac{16.48}{4} = 4.12[/tex]

So, the proportionality constant is 4.12.

d. 2 cups of flour to make 24 cookies

Here,[tex]k =  \frac{24}{2} = 12[/tex]

EUF = {2,4,6,8}

Step-by-step explanation:

Given

D = {xlx is a whole number]

E = {xix is a perfect square between 1 and 9)

F = {xlx is an even number greater than or equal to 2 and less than 9)

We have to find EUF

Writing E and F in set notation

E = {xix is a perfect square between 1 and 9)

There is only one perfect square between 2 and 9

So,

E = {4}

And

F = {2,4,6,8}

Now,

EUF = {4} U {2,4,6,8}

= {2,4,6,8}

Hence,

EUF = {2,4,6,8}

Answer:

The guy wire is 7.2111 ft long

Step-by-step explanation:

Notice that we are in the presence of a right angle triangle formed by: the height (the standing 6 ft pole), the base (the distance from the pole to the anchoring point on the ground), and the actual guy wire. See attached image for reference.

Notice that since pole and ground are perpendicular to each other (at 90 degrees) , the guy wire forms what is called the "hypotenuse" (longest side) of the right angle triangle. We can therefore use the Pythagorean Theorem to solve this problem with the formula for the hypotenuse:

The total number of social worker doing part time work is 9  .

Step-by-step explanation:

Given as :

The percentage of social worker on which Cole surveyed = 20 %

I.e 20 % of the social worker

Or the number of social worker = 45

Let The number of social worker working part time = x

So, x = 20 % of the total social worker

I.e x = 0.2 × 45

∴ x = 9

So , out of total 45 social worker , the number of social worker working part time = 9

Hence The total number of social worker doing part time work is 9  . Answer

Cole surveyed 225 social workers in total.

Understanding Employment Percentages

To find the total number of social workers that Cole surveyed, we can use a simple proportion based on the information given:

→ 20% of the total number of surveyed social workers = 45.

→ Let N be the total number of social workers surveyed.

Write the equation representing the percentage:

→ 0.20 * N = 45

→ Solve for N by dividing both sides of the equation by 0.20:

N = 45 / 0.20

  = 225

So, Cole surveyed a total of 225 social workers.

12) x = 10 or x = -10

13) b = 3 or b = -3.

14) r = 6 or r = -2

15)  n = 0 or -2

Step-by-step explanation:

12) Given, 4|x| + 3 = 43

Now, for x ≥ 0, |x| = x and for x < 0, |x| = -x

So, for x ≥ 0, the equation becomes 4x + 3 = 43

⇒ 4x = 40

⇒ x = 10

Again, for x < 0, we have - 4x + 3 = 43

⇒ - 4x = 40

⇒ x = - 10

Therefore, the solution of the equation is x = 10 or x = -10. (Answer)

13) Given, 3|b| + 5 = 14

Now, for b ≥ 0, |b| = b and for b < 0, |b| = -b

So, for b ≥ 0, the equation becomes 3b + 5 = 14

⇒ 3b = 9

⇒ b = 3

Again, for b < 0, we have - 3b + 5 = 14

⇒ - 3b = 9

⇒ b = - 3

Therefore, the solution of the equation is b = 3 or b = -3. (Answer)

14) 9|2r - 4| + 1 = 73

Now, for 2r - 4 ≥0 i.e. r ≥ 2, then

9(2r - 4) + 1 = 73

⇒ 2r - 4 = 8

⇒ 2r = 12

⇒ r = 6

Again, for (2r - 4) < 0 i.e. r < 2, then

9(4 - 2r) + 1 = 73

⇒ 4 - 2r = 8

⇒ 2r = - 4

⇒ r = -2

Hence, the solutions are r = 6 and r = -2  (Answer)

15) For, 10n + 10 ≥ 0 i.e. n ≥ -1, then

⇒ 10n = 0

⇒ n = 0

Again, for 10n + 10 < 0 i.e. n < -1, then

1 - 4(10n + 10) = 41

⇒ 10n + 10 = - 10

⇒ 10n = -20

⇒ n = -2

[tex]d=240mi[/tex]

For [tex]t=5[/tex]:

[tex]d=60\frac{mi}{hr} (5hr)[/tex]

[tex]d=300mi[/tex]

Therefore, the complete table would be:

t      d

1     60

2    120

3    180

4    240

5    300

Answer:

[tex]x[/tex] ≥ [tex]\frac{7}{6}[/tex]

Step-by-step explanation:

The expression we have is:

[tex]1.5x+3.75[/tex] ≥ [tex]5.5[/tex]

To find the solution of x, we need to clear the inequality until we leave the x on one side.

For this, the first step is to move 3.77 to the left with a minus sign:

[tex]1.5x[/tex]  ≥ [tex]5.5-3.75[/tex]

solving the subtraction on the right side

[tex]1.5x[/tex]  ≥  [tex]1.75[/tex]

and now we move the 1.5 that multiplies to the x, to the right dividing:

[tex]x[/tex] ≥  [tex]1.75/1.5[/tex]

solving the division:  

[tex]x[/tex] ≥ [tex]1.666...[/tex]

since the value 1.666667

is not an exact number, is better to leave it as a fraction:

[tex]1.666...=\frac{7}{6}[/tex]

so the answer is:

[tex]x[/tex] ≥ [tex]\frac{7}{6}[/tex]

so any value equal or greater 7/6 is a solution of the inequality

Answer: it is already in standard form

Step-by-step explanation: for example

To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.

A x+/-By=c and in this case it is 2x-8y=16

The equation 2x-8y=16 is already in the standard form of a linear equation, which is represented as Ax + By = C, where A is 2, B is -8, and C is 16.

In Mathematics, the equation you provided, 2x-8y=16, is already in the standard form. The standard form of a linear equation is usually represented as Ax + By = C, where A, B, and C are integers, and A and B are not both zero. In your equation, 'A' corresponds to 2 (the coefficient of x), 'B' corresponds to -8 (the coefficient of y), and 'C' is equal to 16.

The equation describes a line on a two-dimensional space or plane, and it is used to define the relationship between two variables, x and y. The standard form allows you to quickly identify the x-intercept and y-intercept, which are used to graph the line.

The equation you provided does not need any further adjustments or transformations since it is already in its standard form.

Step-by-step explanation:

The correct question is

Angle a and angle b are vertical angles

Angle a =8x+6

Angle b= 4x+38

Solve for x and find the measure of angle b

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent.

m∠a=m∠b -----> by vertical angles

substitute the given values

[tex](8x+6)\°=(4x+38)\°[/tex]

solve for x

[tex]8x-4x=38-6[/tex]

[tex]4x=32[/tex]

[tex]x=8[/tex]

Find the measure of angle b

[tex]Angle\ b= (4x+38)\°[/tex]

substitute the value of x

[tex]Angle\ b= (4(8)+38)\°[/tex]

[tex]Angle\ b= 70\°[/tex]

Where the above parameters are given, the measure of angle b is 70°.

Given:

Angle a = 8x + 6

Angle b = 4x + 38

Since angle a and angle b are vertical angles, they are equal:

8x + 6 = 4x + 38

Now, let's solve for x:

8x - 4x = 38 - 6

4x = 32

x = 32 / 4

x = 8

Now that we've found x, we can substitute it back into the equation for angle b to find its measure:

Angle b = 4x + 38

= 4 * 8 + 38

= 32 + 38

= 70

So, the measure of angle b is 70°.
