Answer:

-4/3 m/s

Step-by-step explanation:

Using Pythagoras :

a² = x² + c²

5² = x² + y² - - - (1)

The horizontal distance x with respect to time t = 1m/sec

dx/dt = 1m/sec

To obtain the vertical height 'y' with respect to time t when x = 4

5² = x² + y²

Wen x = 4

5² = 4² + y²

25 = 16 + y²

y =√(25 - 16)

y = 3

Differentiate (1) with respect to t

x² + y² = 25 - ---- - (1)

2x * dx /dt + 2y dy/dt = 0

dx/dt = 1

x = 4.

y = 3

2(4)(1) + 2(3) * dy/dt = 0

8 + 6dy/dt = 0

6 dy/dt = - 8

dy/dt = - 8/6

dy/dt = - 4/3

Answer:

[tex] x = 1 \frac{5}{16}[/tex]

Step-by-step explanation:

[tex]8x + \frac{5}{2} = 13 \\ \\ 8x = 13 - \frac{5}{2} \\ \\ 8x = \frac{13 \times 2 - 5}{2} \\ \\ 8x = \frac{26 - 5}{2} \\ \\ 8x = \frac{21}{2} \\ \\ x = \frac{21 }{2\times 8} \\ \\ x = \frac{21}{16} \\ \\ x = 1 \frac{5}{16} \\ [/tex]

Answer: -4,-1.5,1,3.5,6,8.5

Step-by-step explanation: You can check that the difference of any of its consecutive terms is always equal to 2.5.

8.5 - 6 = 2.5

-1.5 - (- 4) = 2.5

3.5 - 1 = 2.5

Answer:

The price is proportional to number of students

Step-by-step explanation:

Given

2010: $1260 for 84 students

2011: $1050 for 70 students

2012: $1395 for 93 students

Required

Determine if the price is proportional to number of students

To do this, we simply divide the price by number of students in each year.

[tex]Ratio = \frac{Price}{Students}[/tex]

In 2010

[tex]Ratio = \frac{\$1260}{84}[/tex]

[tex]Ratio = 15[/tex]

In 2011

[tex]Ratio = \frac{1050}{70}[/tex]

[tex]Ratio = 15[/tex]

In 2012:

[tex]Ratio = \frac{1395}{93}[/tex]

[tex]Ratio = 15[/tex]

Notice that the ratio in the 3 years is 15.

Hence, the price is proportional to number of students

Answer:They are equal

Step-by-step explanation:

they will add up they are just token apart or in pieces

Three different figures are given. The area of the shaded region of all the figures is the same.

We need to determine the highest shaded area among all.

Now, the area of the square is common to all.

Thus,

[tex]\begin{aligned}\rm{Area\;of\;square}&=12^2\\&=144 \;\rm{units^2}\end{aligned}[/tex]

1). Calculate the shaded area for figure A.

The diameter of the circle is 12 units, hence its radius is 6 units.

Therefore,

[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 6^2\\&=36 \pi \;\rm{units^2}\end{aligned}[/tex]

[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]

Thus, the area of the shaded region for figure 1 is [tex]114-36 \pi[/tex].

2). Calculate the shaded area for the figure B.

The diameter of the circle is 6 units, hence its radius is 3 units.

Therefore,

[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 3^2\\&=9 \pi \;\rm{units^2}\end{aligned}[/tex]

[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - 4 \times Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]

Thus, the area of the shaded region for figure 2 is [tex]114-36 \pi[/tex].

3). Calculate the shaded area for figure C.

The diameter of the circle is 4 units, hence its radius is 2 units.

Therefore,

[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 2^2\\&=4 \pi \;\rm{units^2}\end{aligned}[/tex]

[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]

Thus, the area of the shaded region for figure 3 is [tex]114-36 \pi[/tex].

Therefore, the area of the shaded region of all the figures is the same.

Answer:

64

Step-by-step explanation:

cus 8 times 4 is 32 and 32 times 2 is 64

The double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).

To find the double of 8 multiplied by 4, we can perform the following calculation:

Double of 8x4 = 2 * (8 * 4)

First, we multiply 8 and 4:

8 * 4 = 32

Next, we multiply the result by 2:

2 * 32 = 64

Therefore, the double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).

Step-by-step explanation:

pemdas

parentheses- 4 to the 2nd power is 16, 16 + 7 is 23.

exponents- 2 to the 3rd power is 8.

multiplication- 6 x 8 is 48

so then its easy from there. its 48 minus 23, which equals 25

Answer:

0.9!

Step-by-step explanation:

well this is kinda going to be self explantiory just subtract so like 7-8, turn the 7 into 17 and so do 17 -8 which is 9. And since you cannot do 7-8 you have to take the 1 from the 1.7 right so 1-0 will turn into 0-0 with is 0! so 0.9 will be your answer, hopethis helps!
