Answer 2

Answer:

k = 0.5

Step-by-step explanation:

Proportional relationship:

y = kx, where k- constant of proportionality

Find the area of the hexagon. i will mark brainliest and pls explain.

Answers

Answer:

C. 150√3

Step-by-step explanation:

Radius of the inscribed circle is the apothem of the hexagon.

Apothem (a) and half of the side (s) make a 30-60-90 right triangle.

The ratio of the legs, as per property of 30-60-90 triangle:

s : a = 1 : √3 ⇒ s : 5√3 = 1 : √3 ⇒ s = 5

Half the side is s = 5 units, then side of the hexagon is 10 units.

The area of the hexagon:

A = 1/2Pa, P- perimeter, a- apothemA = 1/2(6*10)*(5√3) = 150√3

Correct choice is C

The diagram shows a cuboid of volume V cm3
(a) Show that V = 15 + 16x - x (squared) - 2x (cubed)

Answers

Answer:

Step-by-step explanation:

Length of the cuboid = ((2x + 5) cm

Width of the cuboid = (3 - x) cm

Height of the cuboid = (2x + 5) cm

Since, volume of the cuboid = Length × Width × Height

                                               = (2x + 5)(3 - x)(x + 1)

                                               = [2x(3 - x) + 5(3 - x)](x + 1)

                                               = (6x - 2x² + 15 - 5x)(x + 1)

                                               = (-2x² + x + 15)(x + 1)

                                               = x(-2x² + x + 15) + 1(-2x² + x + 15)

                                               = -2x³ + x² + 15x - 2x² + x + 15

                                               = -2x³ - x² + 16x + 15

                                               ≈ 15 + 16x - x² - 2x³

You go to the store to buy a Playstation 5 which cost 499 dollars. If you had to
pay San Jose's sales tax which is 9.25%. How would you solve the problem to find
the total cost? *

What is the total cost?*

Answers

Answer:

$545.1575

Step-by-step explanation:

Given function:

499,9.25

Solve ways:

combine 9.25% of 499 and 499

Multiply 9.25 by 0.01:

[tex]9.25%[/tex]·[tex]0.01=0.0925[/tex]

Multiply the cost by 0.0925:

[tex]499[/tex]·[tex]0.0925= 46.1575[/tex]

Combine 46.1575 by the first value:

[tex]499+ 46.1575= 545.1575[/tex]

Therefore, the PlayStation 5 will be a total cost of $545.1575.

If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?

Answers

Answer: 0.71

Step-by-step explanation:

Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:

P(R) + P(C) = 1

0.29 + P(C) = 1

P(C) = 1 - 0.29

P(C) = 0.71

Therefore, the probability of a cup drink being cola flavour is 0.71.

Answer:

y = 3x

Step-by-step explanation:

Slope equation:

y2 - y1

--------

x2 - x1

----------------------------------------------------------------------------------------------------------------

         6 - 0          6

m = ----------- =   ----- = 3

         2 - 0           2

Your slope is 3.

----------------------------------------------------------------------------------------------------------------

Equation:

y = mx + b

Plug in the slope and you get:

y = 3x + b

----------------------------------------------------------------------------------------------------------------

Now to find b, you can use either coordinate point. So I will show you both ways :)

(0,0)                                                                     (2,6)

0 = 3(0) + b                                                     6 = 3(2) + b

Multiply 0 and 3                                           Multiply 2 and 3

0 = 0 + b                                                         6 = 6 + b

Subtract 0 to 0                                            Subtract 6 from 6

0 = b                                                                    0 = b

There is no y-intercept

----------------------------------------------------------------------------------------------------------------

Your answer: y = 3x

Let f be differentiable such that f(-2)=3,f(3)=5, f'(-2)=4 and f'(3)=6. Let g be differentiable functions such that g(x)=f^-1 (x) for all x. What is the value of g'(3)

Answers

Answer:

[tex]g'(3)=\frac{1}{4}[/tex]

Step-by-step explanation:

There is a rule in calculus that tells us that:

[tex]g'[f(x)]=\frac{1}{f'(x)}[/tex]

In this case, we know that f(-2)=3, therefore:

g'(3)=g'(f(-2))

So, if we used the rule, we would get that:

[tex]g'[f(-2)]=\frac{1}{f'(-2)}[/tex]

we know that f'(-2)=4, so:

[tex]g'[f(-2)]=\frac{1}{4}[/tex]

or:

[tex]g'[3]=\frac{1}{4}[/tex]

protocol for flushing a cooling water system at a nuclear reactor requires that a drain valve be opened while the fill pumps are active. the drain valve can empty the tank to thr cut-off in 10 minutes. the pump can fill the rank from the cut-off in 14 minutes. during the flushing process, how long will it take for the initially full tank to reach the cut-off level while following the protocol?​

Answers

Answer:

Step-by-step explanation:

drain empties 1/10 of the desired amount per minute

pump fills 1/14 of the desired amount per minute

when both are active, the net drain is 1/10-1/14 = 1/35 of the desired amount per minute

It takes 35 minutes to reach the cut-off level.

6/12+8/12+9/12=23/12=1 11/12

Answer:

D. 1 11/12

Step-by-step explanation:

Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.

Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.

Now, multiply your fractions by the numbers they need to get the denominator to 12.

1/2 x 6/6 = 6/12

2/3 x 4/4 = 8/12

3/4 x 3/3 = 9/12

Add your numerators.

6 + 8 + 9 = 23.

Your fraction should look like 23/12.

Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.

1 and 11/12.

Answers

Answer:

A) 180 square feet.

Step-by-step explanation:

The two rectangles are congruent, therefore having the same area.

The area of a rectangle, or any quadrilateral for that matter, is Length x Width.

12 * 4 = 48

There are two, so multiply this number by 2 and you get 96.

The formula for a trapezoid's area is height *  1/2 * (base 1 + base 2)

The height given is 6 feet. The 1st base is 10 feet, and the longer base is 10 + 4 + 4, this equals 18

The formula is now

[tex]6 * \frac{1}{2} (18 + 10)\\6 * \frac{1}{2} (28)\\6* 14\\=84[/tex]

Now in total, 84 + 96 = 180.
