Answer:

where is the shape ???????

The probability that the first pencil is green and the second pencil is yellow is 0.16.

Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the first pencil is green and the second pencil is yellow = (number of green pencils / total number of pencils) x (number of yellow pencils / total number of pencils)

5/17 x 9/17 = 0.16

Answer:

38 cm

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of all its sides.

We have two unknown length, so let's find their lengths first.

x= 10 -6= 4 cm

y= 9 -2= 7cm

Let's add all the lengths together to find the perimeter:

Perimeter

= 9 +10 +2 +6 +7 +4

= 38 cm

Answer:

a(5) = 1.080

a(10) =  0.393

a(20) =  0.122

Step-by-step explanation:

Take the derivative of velocity v(t) -> acceleration a(t)

v(t) -> a(t)

Quotient Rule: [tex]\frac{u*dv-du*v}{u^2}[/tex]

[tex]120*\frac{x}{5x+13}[/tex]

Make u= 5x+13 and v=x

[tex]120*\frac{x'*(5x+13)-x*(5x+13)'}{(5x+13)^2}\\\\120*\frac{1*(5x+13)-x*(5)}{(5x+13)^2}\\\\120*\frac{(5x+13)-5x}{(5x+13)^2}\\120*\frac{13}{(5x+13)^2} \\\\a(t)=\frac{1560}{(5x+13)^2}[/tex]

Now Subsitute your a(5) , a(10) , a(20). Also, round to 3 decimal place.

a(5) = 1.08033241 = 1.080

a(10) = 0.3930461073 = 0.393

a(20) = 0.122170826 = 0.122

Answer:

  (a) 1.080 ft/s²

  (b) 0.393 ft/s²

  (c) 0.122 ft/s²

Step-by-step explanation:

Acceleration is the derivative of velocity. You are being asked to differentiate the given function and evalutate the derivative at three different times. The function is a rational function, so the formula for the derivative of a ratio is applicable.

  (u/v)' = (vu' -uv')/v²

__

For the given velocity function, the accleration is ...

  v(t) = (120t)/(5t +13)

  a(t) = v'(t) = ((5t +13)(120) -(120t)(5))/(5t +13)² = 1560/(5t +13)²

At t=5, the acceleration is ...

  a(5) = 1560/(5·5 +13)² = 1560/1444 ≈ 1.080 . . . ft/s²

At t=10, the acceleration is ...

  a(10) = 1560/(5·10 +13)² = 1560/3969 ≈ 0.393 . . . ft/s²

At t=20, the acceleration is ...

  a(20) = 1560/(5·20 +13)² = 1560/12729 ≈ 0.122 . . . ft/s²

How to determine the equation of a line?

A line is drawn perpendicular to the line shown in the image. The perpendicular line passes through the coordinate point [tex](F,G)[/tex].

The slope of the line from the graph is-

[tex]m=\dfrac{y-intercept}{x-intercept}\\=2[/tex]

Therefore, the slope of the perpendicular line is [tex]\dfrac{-1}{2}[/tex].

Also, it is being given that Leo's line is passing through the coordinate point [tex](F,G)[/tex].

So, the equation of the Leo's line is-

[tex]y-G=\dfrac{-1}{2}(x-F)[/tex]

Answer:

D. An angle measuring 285 degrees

Step-by-step explanation:

An angle that is coterminal is congruent to the other angle whether negative or positive or more than 360.

An angle that is 645 degrees can be broken down into 360 + 285.

Since 360 is one revolution the angle would finish with 285 degrees.

Therefore the coterminal angle to 645 is 285.

inserting the given values in the formula

[tex]\rightarrow \: z = \frac{27.87 - 30}{1.9} \\\rightarrow \: z = - 1.121[/tex]

Area that's left to z = -1.121

Area that's left to -1.121 = 0.1311

= 13.11%

Hence ,

13.11% of the watermelons weigh less than 27.87 pounds

To find the number of watermelons,

We'll find 13.11% of 400

= 13.11% x 400

= 13.11/100 x 400

= 52.44

hence , approx 52 watermelons would be lesser than 27.87 pounds

Since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

The trapezium is a 2 -dimensional shape consisting of a triangle and a square.

The formula for calculating the area of a trapezoid is expressed as:

Area = 0.5(a + b)h
Area = 0.5(500 + 900) * 800
Area = 700 * 800
Area = 560000 square feet

Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:

Required acre = 560000/43560
Required acre = 12.856 acres

Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

Answer:

79/156

Step-by-step explanation:

we know that cosx is the adjacent side over the hypotenuse.

hence, we can find the opposite side using the pythagorean theorem.

sqrt(13^2 - 5^2)

therefore, the opposite side is 12

opposite: 12

adjacent: 5

hypotenuse: 13

not that cot is adjacent over opposite while sin is opposite over hypotenuse.

So,

12/13 - 5/12

Answer:

[tex]\displaystyle a_1 = 44[/tex]

Step-by-step explanation:

Recall the direct formula for an arithmetic sequence:
[tex]\displaystyle a_n = a_1 + d(n-1)[/tex]

Where d is the common difference.

Therefore, we can write the following two equations:
[tex]\displaystyle \left \{ {a_4 = 107 = a_1 + d(4-1)\atop {a_8 = 191 = a_1 + d(8-1)}} \right.[/tex]

Solve the system. Simplifying yields:
[tex]\displaystyle 107 = a_1 + 3d\text{ and } 191 = a_1 + 7d[/tex]

Subtracting the two equations into each other yields:
[tex]\displaystyle \begin{aligned} (191) - (107) & = (a_1 + 7d) - (a_1 + 3d) \\ \\ 84 & = 4d \\ \\ d & = 21 \end{aligned}[/tex]

Using either equation, solve for the initial term:

[tex]\displaystyle \begin{aligned} 107 & = a_1 + 3(21) \\ \\ a_1 & = 107-63 \\ \\ & = 44\end{aligned}[/tex]

In conclusion, the initial term is 44.

Answer:

[tex]\huge\boxed{\bf\:a_{1} = 44}[/tex]

Step-by-step explanation:

In the given arithmetic series,

We know that,

[tex]\boxed{a_{n} = a + (n - 1)d}[/tex]

Therefore,

[tex]a_{4} = a + 3d = 107 -----(1)\\a_{8} = a + 7d = 191 -----(2)[/tex]

By solving the two equations (1) & (2)....

[tex]\:\:\:\:a + 7d = 191 \\-\underline{a + 3d = 107 }\\ \underline{\underline{\:\:\:\:\:\:\:\:\:\:\:\:\:4d = 84\:\:\:\:\:\:\:\:}}\\\\\\\\4d = 84\\d = 84 \div 4\\\boxed{d = 21}[/tex]

Now, we have the value of the common difference (d). To find [tex]a_{1}[/tex] or a, let's substitute the value of 'd' in (1).

[tex]a + 3d =107\\a + 3(21)=107\\a + 63 = 107\\a = 107 - 63\\\boxed{\bf\:a_{1} = 44}[/tex]
