Write the 1st, 2nd, 3rdand 18thterms for: A) Un= n2 + 4 B) Un = 6n + 5

Answers

Answer:

(a) [tex]U_1 =5[/tex]; [tex]U_2 = 8[/tex]; [tex]U_{18} = 328[/tex]

(b) [tex]U_1 = 11[/tex]; [tex]U_2 =17[/tex]; [tex]U_{18} = 113[/tex]

Step-by-step explanation:

Required

1st, 2nd and 18th terms

To do this, we simply substitute 1, 2 or 18 for n in the given equations

Solving (a):

[tex]U_n =n^2 + 4[/tex]

1st term: n = 1

[tex]U_1 =1^2 + 4[/tex]

[tex]U_1 =1 + 4[/tex]

[tex]U_1 =5[/tex]

2nd term: n = 2

[tex]U_2 = 2^2 + 4[/tex]

[tex]U_2 = 4 + 4[/tex]

[tex]U_2 = 8[/tex]

18th term: n = 18

[tex]U_{18} = 18^2 + 4[/tex]

[tex]U_{18} = 324 + 4[/tex]

[tex]U_{18} = 328[/tex]

Solving (b):

[tex]U_n = 6n + 5[/tex]

1st term: n = 1

[tex]U_1 = 6*1 + 5[/tex]

[tex]U_1 = 6 + 5[/tex]

[tex]U_1 = 11[/tex]

2nd term: n = 2

[tex]U_2 = 6*2 + 5[/tex]

[tex]U_2 =12 + 5[/tex]

[tex]U_2 =17[/tex]

18th term: n = 18

[tex]U_{18} = 6*18 + 5[/tex]

[tex]U_{18} = 108 + 5[/tex]

[tex]U_{18} = 113[/tex]

Trevor pet goat weighed 6 3/ pounds when oit was born. By age 3 the goat weighted 8 times as much. Fill in each box with a number or sysmobe to answer tthis question.

Answers

Answer: 51 pounds

Step-by-step explanation:

Since the goat weighed 6 3/8 pounds and weighed 8 times as much by age 3, the weight of the goat at age 3 will be gotten by multiplying 6 3/8 by 8. This will be:

= 6 3/8 × 8

We change 6 3/8 to an improper Fraction

= 51/8 × 8

= 51 pounds

The weight is 51 pounds

A community theater uses the function p(d)= -5d²+300d -200 to model the profit (in dollars) expected in a weekend when the tickets to a comedy show are priced at d dollars each: Part A: Write and solve an equation to find out the prices at which the theater would earn $2,300 in profit from the comedy show each weekend. Show your reasoning Part B: At what price would the theater make the maximum profit. and what is that maximum profit? Show your reasoning.

Answers

Answer:

A. $66.33B. $4300

Step-by-step explanation:

Given function:

p(d)= -5d² + 300d - 200 Part A

p(d) = 2300, find d:

2300 = -5d² + 300d - 200 5d² - 300d + 200 - 2300 = 05d² - 300d - 2100 = 0d² - 60d - 420 = 0d²- 2*30d + 900 = 1320(d - 30)² = 1320d- 30 = √1320d = 30 + 36.33d = 66.33 Part B

Maximum point of the function is obtained at vertex, which is (x = -b/2a):

d = - 300/-10 = 30

The maximum profit is:

p(30) = -5(30)² + 300(30) - 200 = 4300

A traingle has coordinates at A(-2,0) B(-4,4) and C(1, 6). What are the new locations of the coordinates after a dilation by a scale factor of 4?

Answers

Answer: A (-2,0) --> (-8,0)

B(-4,4) --> (-16,16)

C(1,6)--> (4,24)

Step-by-step explanation:

Multiply each coordinate by 4

A (-2,0) --> (-8,0)

B(-4,4) --> (-16,16)

C(1,6)--> (4,24)

The new locations of the coordinates after dilation by a scale factor of 4 as

A (-2,0) ⇒ (-8,0)

B(-4,4) ⇒ (-16,16)

C(1,6) ⇒ (4,24)

What is dilation?

Dilation is a process for creating similar figures by changing the size.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

As we know dilation factor is the ratio of sides in the original image and the image after dilation.

Dilation factor = 4

Multiply each coordinate by 4

A(-2,0) ⇒ (-8,0)

B(-4,4) ⇒ (-16,16)

C(1,6) ⇒ (4,24)

Answer:

7.8. 10 ^ 3 m / s

Step-by-step explanation:

The computation of the average speed in m/s is shown below:

The average speed equation is

= ΔS ÷ Δt;

As We know that

an entire revolution would be40,000 km

and a satellite takes 85 minutes to complete a revolution,

So,

ΔS = 40,000 km = 40,000,000 m

Δt = 85 min = 5 100 s

Now the average speed is

= 40 000 000 ÷ 5 ÷ 5 100

= 7843.14 m / s

= 7.8. 10 ^ 3 m / s
