Given

Number of servings:

The area of lengthwise pathway is 610 m²

The area of breadthwise pathway is 360 m²

The total area of the two pathways is 985 m²

Given,

The side of square field = 125 m

The width of the lengthwise path = 3 m

The width of the breadthwise path = 5 m

We have to find the area of the two pathways.

Here,

Area of path on length wise = (125 - 3) × 5 = 610 m².

Area of path on breadth wise = (125 - 5 ) × 3 = 360 m²

Area of rectangle at intersection of paths = 5 × 3 = 15 m².

Thus the Total area of two pathways = 610 + 360+15 = 985 m²

Answer:

  -i, 1, i, -1, 1, -1

Step-by-step explanation:

You want the simplified form of various expressions involving powers of i.

The definition of i is ...

  i = √(-1)  or  i² = -1

This value can be used to find other powers:

  i³ = (i²)(i) = -i

  i⁴ = (i²)² = (-1)² = 1

This means any power of i is equivalent to that power modulo 4.

  [tex]-i^{25}=-i^1 = \boxed{-i}\\\\i^{16}=i^0=\boxed{1}\\\\i^{17}=i^1=\boxed{i}\\\\-i^{32}=-i^0=\boxed{-1}\\\\i^{-9}\times -i^{11}=-i^{-9+11}=-i^2=-(-1)=\boxed{1}\\\\\dfrac{i^{23}}{-i^{11}}=-i^{23-11}=-i^{12}=-i^0=\boxed{-1}[/tex]

The equation of line parallel to -x+2y = 30 and passing through (3,6) is x - 2y + 9 = 0.

Given equation is -x+2y = 30

and passing through the point (3,6).

If two lines are parallel, their slopes will be equal.

We know that equation for parallel lines is y = 3x+c

Now, -x + 2y = 30

= 2y = 30 + x

[tex]= y = \frac{30+x}{2}[/tex]

[tex]= y = \frac{30}{2} +\frac{x}{2} \\\\= y = 15 + \frac{x}{2}[/tex]

Therefore slope = [tex]\frac{1}{2}[/tex]

Equation of line with slope and passing through (3,6)

[tex]y-y_{1} = m(x-x_{1}) \\\\y - 6 = \frac{1}{2} (x-3)\\\\[/tex]

2(y-6) = 1(x-3)

2y - 12 = x - 3

x - 2y + 9 = 0

Hence the answer is the equation of line parallel to -x+2y = 30 and passing through (3,6) is x - 2y + 9 = 0.

Terry should mix 29 gallons of the 25%  acid solution and 11 gallons of the 80%  acid solution

Given: 40% acid and 80% acid solutions

Terry needs 40 gal of a 40% acid solution

Let x represent the amount of the 25%  acid solution required in gal

Thus, the amount of the 80% acid solution required will be (40-x) gal

The amount of acid in these solutions is 0.25x + 0.8(40-x)

Since Terry wants exactly 40% or 0.4 of 40 gallons i.e. 0.4×40 gallons

The amount  of acid in these solutions will be:

0.25x + 0.8(40-x) = 0.4×40      Solve for x

0.25x + 32-0.8x  = 16

0.8x-0.25x = 32-16

0.55x = 16

x = 16/0.55 = 29 gallons

40-x = 40 -29 = 11 gallons

Therefore, the amount of the 25%  acid solution required is 29 gallons

and the amount of the 80%  acid solution required is 11 gallons. So she should mix 29 gallons and 11 gallons respectively

In a rectangle two sides are 13 feet and 12 feet.

In right angled triangle sides are 15 feet and 13 feet.

Let x be the hypotenuse of the triangle.

From rectangle opposite sides are equal so the other two sides are equal to 12 feet and 13 feet.

Answer:

[tex]y = -2x-2[/tex]

Step-by-step explanation:

A line being perpendicular means that it has a slope that is an opposite reciprocal of the other line.

In this case:

[tex]x - 2y = 5\\-2y = -x + 5\\y = \frac{x}{2} - \frac{5}{2}[/tex]

The slope of this line is [tex]\frac{1}{2}[/tex] and so the perpendicular slope would be [tex]-2[/tex].

Using the point slope form:

[tex]y - y_1 = m(x-x_1)\\[/tex]

The value of velocity is [tex]v = 7.67\frac{m}{s}[/tex].

The coefficient of restitution is the ratio of the final to initial speed between two bodies after the collision. While a value of 1 indicates a perfectly elastic collision, a value of 0 indicates a perfectly inelastic collision.

The first option is

We can find the displacement by using the area under the graph, which is equal to the displacement. The area of the triangle can be found using the formula below.

[tex]Area = \frac{1}{2} . base . length[/tex]

[tex]Area = 0.5m.50m.50. = 1250 m^{3}[/tex]

We use the conservation of energy. So, we equate the potential energy and the kinetic energy.

[tex]E_{pot} = E_{kin}\\ \\ m.g.h = \frac{1}{2}.m.v^{2}[/tex]

The mass is cancelled out in the above equation, and we re-arrange with respect to velocity.

[tex]v^{2} = 2.g.h\\ \\v = \sqrt{2.9.81\frac{m}{s^{2} }.3m } = 7.67\frac{m}{s}[/tex]

In the right-angled triangle ABC, CA is 4.2cm.

What is a right-angled triangle? How to identify it?

Any angle that is a right angle or has one of its interior angles equal to 90 degrees is considered to be in a right-angled triangle. This triangle is also known as the right triangle or the 90-degree triangle for this reason. Trigonometry heavily utilizes the right triangle. In this article, let's learn more about this triangle.

By applying Pythagoras' theorem, one can determine whether a triangle has a right angle. If the squares of the triangle's two shorter sides equal the square of the hypotenuse, a right angle is present.

Solution explained:

A/Q, we have

BC = 9.2cm and m∠A = 63°

Using the tangent ratio formula (ratio of a side that is not the hypotenuse to a side that is near to an angle), we get

[tex]tanA = \frac{BC}{CA}[/tex]

tan 63° = [tex]\frac{9.2}{CA}[/tex]

CA = [tex]\frac{9.2}{1.96}[/tex]     (tan 63° = 1.96)

now let's see how many liters we have hmmm 2 of hazel, 1 of alcohol and the rest in boric acid, to make a total of 5 liters, so boric acid must be 2, since 2 + 1 + 2 = 5.

how much alcohol is there  in 95% of 1? well, no to bore you to death, is just 0.95 liters, and we know the boric acid has no alcohol.

Answer:

Step-by-step explanation:

you'll need to know  L'Hôpital's Rule.  Obviously this problem goes to zero in the denominator if you let x go to zero, which is a big problem :P  sooo use L'Hopital's rule to solve this messy problem.  

L'Hoptial's rule takes the advantage that you can find the derivative of something but still find it's limit just like you didn't take a derivative.  soo

take derivative of numerator and denominator  separately

remember how to take derivative of  sin^2(3x) ??

pull the two down,   then chain rule

d/dx (sin^2(3x) =   2sin(3x) * cos(3x) * 3    = 6*sin(3x)*cos(3x)

d/dx (4x^2)  = 8x

we still have the same issue if we take the limit if x goes to zero :0

but it's okay... just take L'Hopitals' again :P

d/dx (6*sin(3x)*cos(3x)) =  6*cos(3x) *3 *(-sin(3x)*3 = 54*cos(3x)*(-sin(3x))

d/dx (8x) = 8

now we can let the limit go to zero

lim ( x ->0)[54*cos(3x)*(-sin(3x)) / 8]

we can see that sin(x) will get closer and closer to zero so we have 0/8

so we can fairly say,  without guessing, that yes... this limit goes to zero as X goes to zero.  :)  nice
