Answer:

3, 5, 7, 9, 11, .........

Step-by-step explanation:

Given

[tex]S_{n}[/tex] = n(n + 2) , then

S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3

S₂ = 2(2 + 2) = 2(4) = 8

S₃ = 3(3 + 2) = 3(5) = 15

Thus

a₂ = S₂ - S₁ = 8 - 3 = 5

a₃ = S₃ - S₂ = 15 - 8 = 7

The first 3 terms are 3, 5, 7

This is an AP with common difference d = 2, then

a₄ = a₃ + 2 = 7 + 2 = 9

a₅ = a₄ + 2 = 9 + 2 = 11

and so on

That's the right answer on edge

The shadow of a 265m long building would be b. 151 m

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given,  Ms. Kraus is 1.75 m tall. When her shadow is 1 m.

Let the shadow of a 265 m tall building be 'x' m.

Therefore by the ratio proportion method.

1.75 : 1 : : 265 : x.

1.75/1 = 265/x.

1.75x = 265.

x = 265/1.75.

x = 151.42 Or 151 m.

Answer:

y=5x+4

Step-by-step explanation:

You would have to look up how to do the hadn written way of figuring out this but I just used my calculator. To do this with your TI-84 or newer calculator, press "stat" and go into "edit". You will see some columns with the names "L1, L2, L3, etc." which stand for lists. put your x values in "L1" and their corresponding y values next to them in "L2". When you're done press stat again and move right to the heading "Calc". Go down to number 4 which should say "LinReg(ax+b)" next to it and press enter. now you should see "Xlist" and "Ylist" with "L1" and "L2" beside them respectively. Once that is set, go down to "Calculate" and press enter and it should give you slope intercpet form and what "a" and "b" are. You're welcome.~ ;P

Print-O-Rama

# shirts    total  cost

10                $95

50             $375  

a. Does either pricing model represent a proportional relationship between the quantity of t-shirts and the total cost? Explain.

Value T’s and More offers a proportional relationship since each t-shirt costs $8 regardless of the number of t-shirts

b. What is the constant of proportionality of Value T’s and More? What does it represent?

$8 per t-shirt

f(c) = $8t

the function of total cost = $8 times the number of t-shirts ordered

c. How much is Print-o-Rama’s set-up fee?

using the high-low method

variable cost = ($375 - $95) / /50 - 10) = $7 per t-shirt

fixed cost (set-up fee) = $375 - (50 x $7) = $25

d. If you need to purchase 90 shirts, write a proposal to your teacher indicating which company the team should use. Be sure to support your choice. Determine the number of shirts that you need for your team.

purchasing 90 t-shirts at Print-o-Rama costs = $25 + (90 x $7) = $655

purchasing 90 t-shirts at Value T’s and More costs = 90 x $8 = $720

you should purchase the t-shirts at Print-o-Rama since the cost is lower.

Answer:

g(x) = 1/4 f(x)

Step-by-step explanation:

f passes through the origin and has a slope of 1.

f(x) = x

g passes through the origin and has a slope of 1/4.

g(x) = 1/4 x

Substituting:

g(x) = 1/4 f(x)

Answer:

All real square roots of 25 is +5 and -5.

Step-by-step explanation:

When you square root something, you take the positive and negative of the number, so the square root of 25 would be 5 and -5.

When you do 5 times 5, you get 25 and when you do -5 times -5, you get 25 as well, this is why we do the negative as well.

#teamtrees #WAP (Water And Plant)

It is found that all the real square roots of 25 are 5 and -5.

The function is strictly increasing function for x ≥ 0.

Assuming that all the values of x are ≥ 1, whenever there is increment in the value of 'x', the value of y increases too Perfect square are those integers whose square root is an integer. Let x-a be the closest perfect square less than x, and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).

When we do square root of something, we take the positive and negative of the number, so the square root of 25 would be 5 and -5.

When we do 5 times 5, we will get 25 and when we do -5 times -5, we will get 25 as well, this is why we do the negative as well.

Hence, all the real square roots of 25 are 5 and -5.

i believe its √49.

the square root of 49 is 7, and 7 is a rational number

Answer: x = - 12

8x + 45 = 10x + 69

⇔ 10x - 8x = 45 - 69

⇔ 2x = -24

⇔ x = -12

Step-by-step explanation:

Answer:

x = -12

Step-by-step explanation:

8x + 45 = 10x + 69

8x = 10x + 24

-2x = 24

x = -12

The line is passing through (2, 0) and (0, 0.8) and the slope is 0.4. Then the correct option is A.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

From the line, we can observe that the line is passing through (2, 0) and (0, 0.8).

Then the slope of the line will be

Slope = (0.8 – 0) / (0 – 2)

Slope = 0.4

Then the correct option is A.

Answer: 6x^3−16x^2−14x+24 is your answer

have a good day

Yours,

Nathaniel

Step-by-step explanation:

The expression 2(3x + 4)(x - 1)(x-3) is equivalent to the expression 6x³ - 16x² - 14x + 24 option (A) is correct.

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The expression is:

= 2(3x + 4)(x - 1)(x-3)

After the multiplication of the polynomial:

= 2(3x² + x - 4)(x - 3)

Again multiplication:

= 2(3x³ - 8x² - 7x + 12)

= 6x³ - 16x² - 14x + 24

Thus, the expression 2(3x + 4)(x - 1)(x-3) is equivalent to the expression 6x³ - 16x² - 14x + 24 option (A) is correct.

Answer:

3 peanut cookies

Step-by-step explanation:

Given that :

Plate 1:

Number of chocolate chip = 4

Number of peanut butter cookies = 1

Probability of drawing chocolate chip cookies from plate 1 :

Probability =( number of required outcome / Total possible outcomes)

P(chocolate chip) = 4 / 5

Plate 2:

Number of chocolate chip = 2

Number of peanut butter cookies = p

P(chocolate chip) = 2 / (2 + p)

Probability of drawing chocolate chip from plate 1 and then plate 2 = 8/ 25

(4/5) * 2/(2+p) = 8/ 25

8 / (10 + 5p) = 8/ 25

8(10 + 5p) = 8 * 25

80 + 40p = 200

40p = 200 - 80

40p = 120

p = 3

Hi! unfortunatly I'm not good at math BUT I would suggest to copy this question and paste on google. Sometimes it gives you the answers. If not then, I'm really sorry! have a good day :)

The probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The amount on the receipt = {8, 10, 10, 15, 25, 32}

Total outcome = 6

The amounts are grouped as more than $20 and less than $20.

The event is the amount on receipt more than $20 = {25, 32}

Total favourable outcome = 2

Probability = 2/6 = 1/3 or

= 0.33

Thus, the probability of selecting a receipt of more than $20 is 1/3 or  0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.
