The volleyball is 14 feet above the ground at the instant the player begins her jump.

It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.

We have two equation for two different situations:

\(\rm h(t) = 14 - 16t^2\\\)              (falling volleyball as a function of time t)

\(\rm h(t) = 7+24t-16t^2\)       (the hands of a player jumping up to spike the    

                                        ball as a function of time t)

First, we have to find the height of the ball above the ground at the instants the player begins to jump:

At t = 0 when the player begins to jump

Put t = 0 in the second equation, we get:

\(\rm h(0) = 7+24\times 0-16\times0^2\)

Height of the hand, h = 7 units

Now put t = 0 in the first equation, we get;

\(\rm h(0) = 14 - 16\times0^2\)

h = 14 units.

Thus, the volleyball is 14 feet above the ground at the instant the player begins her jump.

tan 145° is equal to csc 55°. Given that csc 55° is not provided in the options, none of the given options is correct. cotangent is the reciprocal of the sine function.

To find the value of tan 145°, we can use the relationship between tangent and cotangent:

tan x = 1 / cot x

Since cotangent is the reciprocal of the sine function, we can rewrite the given equation as:

csc 55° = 1 / sin 55°

To find the value of sin 55°, we can use the fact that sin x = cos (90° - x):

sin 55° = cos (90° - 55°)

       = cos 35°

Now, we need to find the value of cos 35°. We can use a trigonometric identity:

cos (90° - θ) = sin θ

cos 35° = sin (90° - 35°)

       = sin 55°

Substituting this value back into the equation, we have:

csc 55° = 1 / sin 55°

       = 1 / cos 35°

Now, let's find the value of tan 145° using the relationship between tangent and cotangent:

tan 145° = 1 / cot 145°

Since cotangent is the reciprocal of the sine function, we can rewrite the equation as:

tan 145° = 1 / sin 145°

To find the value of sin 145°, we can use the fact that sin x = sin (180° - x):

sin 145° = sin (180° - 145°)

        = sin 35°

Now, we have:

tan 145° = 1 / sin 145°

        = 1 / sin 35°

Since we previously found that csc 55° = 1 / cos 35°, we can substitute this value into the equation:

tan 145° = 1 / sin 35°

        = csc 55°

Therefore, tan 145° is equal to csc 55°. Given that csc 55° is not provided in the options, none of the given options is correct.

"Centripetal is the word used to describe a vector that always points toward the centre of a circular path."

The centripetal acceleration vector is an acceleration in the radial direction that is directed towards the centre of the circular line of motion. It runs perpendicular to the linear motion, or v.

The direction of the velocity shift for a ball travelling around a curve is in the direction of the curve's centre. Centripetal acceleration is the acceleration that is directed towards the centre of a curved or circular route.

Any force that changes the path of motion towards the centre of a circular motion is known as a centripetal force. The portion of the force that produces the centripetal force is the part that is perpendicular to the velocity.

The maximal flow from node 1 to node 7 in the given network needs to be determined, along with identifying the associated minimal cut. Additionally, the associated linear-programming problem needs to be written.

To find the maximal flow from node 1 to node 7, various algorithms like the Ford-Fulkerson algorithm or the Edmonds-Karp algorithm can be used. These algorithms iteratively find augmenting paths and update the flow until no more augmenting paths exist. The maximal flow represents the maximum amount of flow that can be sent from the source (node 1) to the sink (node 7).

The associated minimal cut can be found by identifying the set of edges whose removal would disconnect the source from the sink. The minimal cut represents the minimum capacity required to disconnect the source and sink nodes.

To write the associated linear-programming problem, we need to define decision variables, objective function, and constraints that represent the flow network. The objective function is typically to maximize the flow from the source to the sink, subject to capacity constraints on the edges and flow conservation constraints at each node.

Detailed calculations and graph analysis would be required to find the specific maximal flow, associated minimal cut, and formulate the linear programming problem for the given network.

Answer:

the answer is (a) 28.

Step-by-step explanation:

The given situation can be represented by a linear equation of the form:

Cost = mx + b

where "m" is the slope (the rate of change of cost with respect to time), "x" is the number of hours of the tour, and "b" is the y-intercept (the cost when x = 0).

In this case, the y-intercept is $60, which represents the one-time fee. The cost increases by $28 per hour, so the slope is:

m = $28/hour

Therefore, the answer is (a) 28.

Step-by-step explanation:

Answer:

1) ✅ Correct!

2) ❌Incorrect. The correct answer is 1 in 4.

Step-by-step explanation:

2) The correct answer is 1 in 4.

⭐When calculating the probability of an event, you have to divide the number of desired possibilities by the number of total possibilities.

We want to know what is the chance for the spinner to land on "no prize". There are 2 "no prize" options. Thus, "no prize" (2) will be our desired possibility.

In total, there are 8 options on the wheel. Thus, 8 will be the number of total possibilities.

Divide the numbers respectively.

\(\frac{2}{8}\)

Simplify the result. 2 is the GCF of the numerator and denominator.

\(\frac{1}{4}\)

∴ There is a 1 in 4 chance of the spinner landing on "no prize".

Answer:

below explained briefly

Step-by-step explanation:

(a) to find the area of parallelogram use the formula: b * h = 30 * 20 = 600m^2

(b) to find the area of shaded of this one: first we need to find the area of rectangle and then area of two triangle and subtract them with rectangle.

area of rectangle : length * width = 25 * 7  = 175 cm^2

area of two triangles = 2(1/2*b*h) = 2 ( 1/2 * 7 * 5 ) = 35 cm^2

area of shaded = 175 - 35 = 140 cm^2

(c) there different methods of finding area of this figure.

one of the famous methods are that we know it a equilateral triangle thus all sides are 60 degree

formula : 1/2 * a * b * sin(C)

using this formula : 1/2 * 8 * 8 * sin( 60 )

                              : 27.7 cm^2

Answer:

t = 36

Step-by-step explanation:

If you divide the equation by 5, you have ...

 x^2 -7.2x +t/5 = 0

The opposite of the sum of the roots is the coefficient of the linear term, so is 7.2. If the roots are "r" and "5r", then their sum is r+5r = 6r, so the value of r is.

 7.2/6 = 1.2

The roots are 1.2 and 5·1.2 = 6.

The constant term t/5 is the product of the roots, so ...

 t/5 = 1.2 · 6

 t = 6·6 = 36 . . . . . multiply by 5

A ≈ 14.8 units²

Step-by-step explanation:

the area (A) of the triangle is calculated as

A = \(\frac{1}{2}\) yz sin Y ( that is 2 sides and the angle between them )

where x is the side opposite ∠ X and z the side opposite ∠ Z

here y = XZ = 4.3 and z = XY = 7 , then

A = \(\frac{1}{2}\) × 4.3 × 7 × sin79°

   = 15.05 × sin79°

   ≈ 14.8 units² ( to 1 decimal place )

The measure of the angle m<ROS = 14°.

What is the angle?

An angle is a geometric figure that is defined by two rays that have the same endpoint. The rays are called the sides of the angle and the common endpoint is called the vertex of the angle. The angle is the amount of rotation between the two rays, measured in degrees or radians.

In the given figure,

m<QOS = 46, m<POR = 58 and m<POQ = 26

m<POR = m<POQ + m<QOR

58 = 26 + m<QOR

m<QOR = 32

m<QOS = m<QOR + m<ROS

46 = 32 + m<ROS

m<ROS = 14

Hence, the measure of the angle m<ROS = 14°.

The probability that at least one of the 5 people selected has been vaccinated is 0.998, or 99.8%.

To solve this problem, we can use the complement rule, which states that the probability of an event happening is equal to 1 minus the probability of the event not happening. In this case, the event we're interested in is at least one person being vaccinated.
First, we need to find the probability that none of the 5 people selected have been vaccinated. Since 62% of the population has been vaccinated, that means 38% have not been vaccinated. So the probability of any one person not being vaccinated is 0.38.
Using the multiplication rule for independent events, the probability that all 5 people have not been vaccinated is:
0.38 x 0.38 x 0.38 x 0.38 x 0.38 = 0.002
Now we can use the complement rule to find the probability that at least one person has been vaccinated:
1 - 0.002 = 0.998
So the probability that at least one of the 5 people selected has been vaccinated is 0.998, or 99.8%.
