(answer to get BRAINLYLIST)algorithm to find fehrenhit where clcius is 99

Answer:

A.   (f + g)(1) = - 9

B.    (f - g)(0) = -7

C.    (fg)(3) = 0

Step-by-step explanation:

A.    (f + g)(1) = f(1) + g(1)               f(1) = 1^2 - 9 = 1 - 9 = - 8       g(1) = 1 - 2 = - 1

                    = -8 -1 = -9

B.     (f - g)(0) = f(0) - g(0)             f(0) = 0^2 - 9 = 0 - 9 =  -9      g(0) = 0 - 2 = -2

                      =  -9 + 2 = -7

C.      (fg)(3) = f(3)(g(3)                   f(3) = 3^2 - 9 = 9 - 9 = 0    g(3) = 3 - 2 = 1

                    = 0(1) = 0

Let f, s, and t denote the hours needed by the first, second, and third sellers, respectively, to sell a given plant.

"In one hour, the first grower sells 3 fly traps … The second grower sells 1 fly trap … The third grower sells 3 fly traps …" - this means that for each hour f, the first grower sells a total of 3f fly traps. Similarly, the second grower sells 1s fly traps, and the third grower sells 3t fly traps. Together, they want to sell 39 fly traps, so that

3f + s + 3t = 39

You set up two more equations for the sundews and bladderworts:

f + 2s + 2t = 30

2f + s + 2t = 28

Now write the system of equations in augmented matrix form and row reduce it:

[tex]\left[\begin{array}{ccc|c}3&1&3&39\\1&2&2&30\\2&1&2&28\end{array}\right][/tex]

Add row 1 to -3 (row 2); this is to say, treating each row as a list, multiply through the second row by -3, then add the first row to that result. For example,

(3, 1, 3, 39) + -3 (1, 2, 2, 30) = (3, 1, 3, 39) + (-3, -6, -6, -90)

… = (3 - 3, 1 - 6, 3 - 6, 39 - 90)

… = (0, -5, -3, -51)

Also, add 2 (row 1) to -3 (row 3) :

[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&-5&-3&-51\\0&-1&0&-6\end{array}\right][/tex]

Multiply through the last two rows by -1 to make everything positive, and swap them around:

[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&1&0&6\\0&5&3&51\end{array}\right][/tex]

Next, add -5 (row 2) to row 3 :

[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&1&0&6\\0&0&3&21\end{array}\right][/tex]

Multiply through row 3 by 1/3 :

[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&1&0&6\\0&0&1&7\end{array}\right][/tex]

Add -1 (row 2) and -3 (row 3) to row 1 :

[tex]\left[\begin{array}{ccc|c}3&0&0&12\\0&1&0&6\\0&0&1&7\end{array}\right][/tex]

Multiply through row 1 by 1/3 :

[tex]\left[\begin{array}{ccc|c}1&0&0&4\\0&1&0&6\\0&0&1&7\end{array}\right][/tex]

This row-reduced matrix tells you that f = 4, s = 6, and t = 7. In other words, in order for the three growers to collectively sell the required number of plants, the first seller needs to work for 4 hours, the second seller needs to work for 6 hours, and the third seller needs to work for 7 hours.

Answer:

Well, for (D), the answer would be 32.

Step-by-step explanation:

Because, 20 +12 =32. And 32 - 12 = 20. With the other ones that add, its the same way. You can just for example, if its -5 + b = -40, you can just go 5 - 40= which equals 35. Which should give you 40 if you add 35 and 5 together.

Step-by-step explanation:

a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.

Step-by-step explanation:

Step-by-step explanation:

Hi,

63 = 5x + 18 represents this situation.

63 = 5x + 18

45 = 5x

9 = x

So, the possible number of mins are 1, 2, 3, 4, 5, 6, 7, 8, and 9.

You can also write this as x ≤ 9

Answer:

15 cm

Step-by-step explanation:

Since the square's side length is 8 cm, and one of its sides is the short leg of the triangle, the short leg of the triangle is 8 cm

Using the pythagorean theorem, solve for b (the missing side length x)

a² + b² = c²

8² + b² = 17²

64 + b² = 289

b² = 225

b = 15

So, the missing side length is 15 cm

Answer:

Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}

Step-by-step explanation:

Let regular non discounted price of 7 pizzas be x

x - 22.5 = 82.5

x = 82.5 + 22.5

x = 105 (Regular Non discounted price of 7 pizzas)

Regular Price of 7 pizzas = 105

Regular price of 1 pizza = 105 / 7 = 15

Answer:

x = 3 and 1/3, or 3.333333...

Step-by-step explanation:

I'm assuming again that you want to find x

–4 + 3 ( 2 – x) = –8

Multiply

-4 + 6 - 3x = -8

Add 4 to both sides

6 - 3x = -4

Subtract 6 from both sides

-3x = -10

Multiply by -1

3x = 10

Divide by 3

x = 10/3

f=50

d=40

Answer:

m=-4/3

Step-by-step explanation:

The equation for slope is y2-y1/x2-x1

m=(y2-y1)/(x2-x1)

m=(12--4)/(1-13)

m=16/-12

m=-4/3

Answer:

x = 17.2

Step-by-step explanation:

[tex]x = 21 \: cos 35 \degree \\ \\ x = 17.20219293 \\ \\ x = 17.2[/tex]

Answer:

17.2

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos = adjacent/ hypotenuse

cos 35 = x/21

21 cos 35 =x

17.2021293=x

Rounding to the nearest tenth

17.2

Answer:

D. 5

Step-by-step explanation:

Based on the midsegment theorem of a trapezoid, thus:

QR = ½(OP + MN)

Substitute

27 = ½((5x - 7) + (6x + 6))

27 = ½(5x - 7 + 6x + 6)

Add like terms

27 = ½(11x - 1)

Multiply both sides by 2

2*27 = 11x - 1

54 = 11x - 1

54 + 1 = 11x

55 = 11x

55/11 = x

5 = x

x = 5

Answer:

2/3

Step-by-step explanation:

A six sided number cube :

Sample space = (1, 2, 3, 4, 5, 6)

Non composite numbers on a six sided number cube = (1, 2, 3, 5)

Probability of an event = required outcome / Total possible outcomes

Required outcome = number of non composite numbers = 4

Total possible outcomes = sample space = 6

P(not composite) = 4 / 6 = 2/3

Answer:

t = 2.5 years

Step-by-step explanation:

Given that,

Principal = $5000

Interest = $250

Rate of interest = 2%

We need to find the time. We know that,

[tex]I=\dfrac{PRT}{100}[/tex]

Put all values to find T.

[tex]T=\dfrac{100I}{PR}\\\\T=\dfrac{100\times 250}{5000\times 2}\\\\T=2.5\ yrs[/tex]

So, it will take 2.5 years.

Answer:

d = 15.8 m

Step-by-step explanation:

Apply the Pythagorean Theorem to find the length of the diagonal.  The correct equation for this particular rectangle is

d = √(9² + 13²) = √250 = √25·√10 = 5√10

To the nearest tenth, this comes to d = 15.8 m
