Answer: C.[tex]\left \{ {{a1=-2} \atop {an=a(n-1)+3}} \right.[/tex]

because it is the arithmetic progression with d = 3

=> a(n) = a1 + (n - 1).3

so, have: a1 = -2

               an = a(n-1) + 3

Answer:

Time = 3secs

Max height = 56m

Step-by-step explanation:

Given the height reached by the rocket modeled by the equation;

h(x) = -5(x - 3)² + 56 where;

x is in seconds

The rocket velocity at its maximum height is zero.

Hence dh/dx = 0

dh/dx = 2(-5)(x-3)

dh/dx = -10(x-3)

Since dh/dx = 0

0 = -10(x-3)

0 = -10x + 30

10x = 30

x = 3secs

Hence it takes 3 secs to reach the maximum height.

Get the maximum height reached by the rocket. Substitute x = 3 into the equation given;

Recall that:

h(x) = -5(x - 3)² + 56

If x  = 3

h(3) = -5(3 - 3)² + 56

h(3) = 0 + 56

h(3) = 56

Hence the maximum height that the rocket reaches is 56m

Answer:

6,250$ is the overhead for department a

The distribution of overhead to Department A based on sales is $6250.

A recurring cost of running a firm is referred to as overhead or overhead charge. While operating expenses like material and labor, overheads could easily be linked to or recognized with any one revenue unit.

They are operating costs for a business that cannot be connected to the creation or production of a good or service. They are really the costs a business must pay to remain open, independent of how successful it is.

Department A has sales of $200,000

Department B has sales of $600,000

Therefore the ratio between the two departments will be:

200000: 600000

= 1 : 3

The overhead expense for both the department combined are $25,000

The share of department A will  be at

= 25000 * (1/4)

= $6250

Answer:

The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].

Step-by-step explanation:

Let suppose that effects from air friction and Earth's rotation can be neglected, so that the softball can be modelled experiment a free fall, that is, an uniform accelerated motion due to gravity. From we know the initial velocity and position of the position and we can determine the final position of the ball as a function of the final velocity:

[tex]v_{f}^{2} = v_{o}^{2}+2\cdot a \cdot (s_{f}-s_{o})[/tex] (1)

Where:

[tex]s_{o}[/tex], [tex]s_{f}[/tex] - Initial and final position of the softball, measured in feet.

[tex]a[/tex] - Acceleration, measured in meters per square second.

[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final velocities of the softball, measured in feet per second.

If we know that [tex]v_{o} = 50\,\frac{ft}{s}[/tex], [tex]a = -32.174\,\frac{m}{s^{2}}[/tex] and [tex]s_{o} = 4\,ft[/tex], then the equation that models the situation is:

[tex]v_{f}^{2} = 2500-64.348\cdot (s_{f}-4)[/tex]

Then, we clear the final position of the softball:

[tex]-\frac{v_{f}^{2}-2500}{-64.348} = s_{f}-4[/tex]

[tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex]

The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].

Answer:

2.5 cups of milk

Step-by-step explanation:

Given that,

A cake recipe calls for 1.5 cups of milk and 3 cups of flower.

Seth made a mistake and used 5 cups of flour.

We need to find number of cups of milk he use to keep the proportions correct. Let he used x cups of milk.

[tex]\dfrac{1.5}{3}=\dfrac{x}{5}\\\\x=\dfrac{1.5\times 5}{3}\\\\x=2.5[/tex]

Hence, he should use 2.5 cups of milk.

Answer: 35%

Step-by-step explanation:

You did not give the numbers. Let me help out by giving some figures and explain with that.

Latoya needs to make a total of 60 deliveries this week. So far she has completed 21 of them. What percentage of her total deliveries has Latoya completed?

To solve this, we divide 21 by 60 and then multiply by 100. This will be:

= (21 / 60) × 100

= 7/20 × 100

= 35%

Answer: Nicole rented the scooter for 10 days.

Step-by-step explanation:

50 + 25 = 75 (Day 1)

75 + 25 = 100 (Day 2)

100 + 25 = 125 (Day 3)

125 + 25 = 150 (Day 4)

150 + 25 = 175 (Day 5)

175 + 25 = 200 (Day 6)

200 + 25 = 225 (Day 7)

225 + 25 = 250 (Day 8)

250 + 25 = 275 (Day 9)

275 + 25 = 300 (Day 10)

Answer:

3y = 2x + 24

Step-by-step explanation:

The correct question is as follows;

Write an equation of the line that goes through the point (6, 12) and has a slope of 2/3

Solution

Here, we have a point and a slope, and we want to write the equation of the line

The method we shall use here is the point slope method

Mathematically, that will be;

y-y1 = m(x-x1)

(x1,y1) = (6,12)

m = 2/3

y-12 = 2/3(x-6)

3(y-12) = 2(x-6)

3y-36 = 2x - 12

3y = 2x -12 + 36

3y = 2x + 24
