Answer: The square root of 1681 is 41.

Answer:

41

Step-by-step explanation:

It is 41

41 * 41 = 1681

41 ^ 2 = 1681

The length of a curve C is given by the integral,

\(\displaystyle\int_C\mathrm ds\)

where the line element ds is

\(\mathrm ds=\sqrt{\left(\dfrac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt\)

where \(x=x(t)\) and \(y=y(t)\) are parameterizations of C.

In this case, we have

\(x(\theta)=r(\theta)\cos\theta\)

\(y(\theta)=r(\theta)\sin\theta\)

Differentiate with respect to \(\theta\) to get

\(\dfrac{\mathrm dx}{\mathrm d\theta}=\dfrac{\mathrm dr}{\mathrm d\theta}\cos\theta-r(\theta)\sin\theta\)

\(\dfrac{\mathrm dy}{\mathrm d\theta}=\dfrac{\mathrm dr}{\mathrm d\theta}\sin\theta+r(\theta)\cos\theta\)

\(\dfrac{\mathrm dr}{\mathrm d\theta}=\sin\left(\dfrac\theta2\right)\cos\left(\dfrac\theta2\right)=\dfrac12\sin\theta\)

So the arc length is

\(\displaystyle\int_C\mathrm ds=\int_0^a\sqrt{\left(\dfrac12\sin\theta\cos\theta-\sin^2\left(\dfrac\theta2\right)\sin\theta\right)^2+\left(\dfrac12\sin\theta\sin\theta+\sin^2\left(\dfrac\theta2\right)\cos\theta\right)^2}\,\mathrm d\theta\)

\(=\displaystyle\int_0^a\sqrt{\sin^2\left(\dfrac\theta2\right)}\,\mathrm d\theta\)

\(=\displaystyle\int_0^a\sqrt{\frac{1-\cos\theta}2}\,\mathrm d\theta\)

Therefore by solving the equations we get to know that 196 children and  200 adults were present on that day.

equation, a declaration of equivalence between two expressions with variable- and/or number-filled expressions. In essence, equations are questions, and efforts to discover a method for answering them have fueled the growth of mathematics. Equations range in complexity from straightforward addition-and-multiplication equations in mathematics through differential equations, exponential equations that use exponential expressions, and integral equations.

Let's initially configure our system by giving the letters x and y meanings. Assume x is the number of kids and y is the number of adults.

Children are priced at $1.50, while adults are priced at $4.00. We multiply the total number of children, x, by 1.5 to get how much each child will cost. 1.5x is used to indicate this. We will use 4y for adults, whose entry fee is $4. On the specified day, $1094 in total revenue was earned. This sum requires the addition of 1.5x and 4y.

1.5x + 4y = 1094 works for the money equation involved.

Second equation: The total number of individuals present on the day is 283. X and Y, or the number of children and adults, must be added together to arrive at this figure.

x + y = 396

System of equations:

1.5x + 4y = 1094

x +   y = 396

Thus,

x + y = 396  

y = 396- x

Substitute y = 396 - x into the first equation.

1.5x + 4 (396 - x) = 1094

1.5x + 1584 - 4x = 1094  

1584 - 2.5x = 1094      

-2.5x = -490                  

x = 196

Substitute x =196 back into y = 396 - x

y = 396 - 196 = 200

Therefore by solving the equations we get to know that 196 children and  200 adults were present on that day.

Definition of constants: Contants are numbers that have no variables.

To find the constants of the expression 7r - 3 + 2s + 5, simply look for numbers without variables. We can see that the constants are -3 and 5, which matches Option B.

Hence, Option B is correct.

If you were to plot the square root of 15 on a number line, the position would be point A.

The first thing to do is to solve for the square root of 15 which is:

= √15

= 3.87

On a number line therefore, the position would be after 3 but close to 4 because the value can be rounded up to 4.

-11x-10y=17

lets find x

5x-7y=50

5x=7y+50

x=7/5 y +10

we will substitute our x in the first eq

-11(7/5 y+10)-10y=17

-77/5 y-110 -10y=17

we solve this equation and we get y=-5

so if we have y=-5

5x-7(-5)=50

5x+35=50

5x=50-35

5x=15

x=3

16 quarts is equal to 4 gallons.

The correct option is C.

To convert quarts to gallons, we divide the number of quarts by 4 (since there are 4 quarts in a gallon).

Given that we have 16 quarts, we can calculate:

16 quarts / 4 quarts/gallon

= 4 gallons

Therefore, 16 quarts is equal to 4 gallons.

The missing terms in the geometric progression given are:

x = 10      y = 20

The nth term of a Geometric progression is expressed by the formula:

an = ar^(n - 1)

Where we have:

an = nth term

a = first term of the geometric progression

n = number of terms

r = common ratio

We are given the geometric progression 5, x, y, and 40, where:

a1 = 5

a4 = 40

Therefore, we have:

40 = 5 * r^(4 - 1)

40 = 5 * r³

40/5 = r³

8 = r³

r = ∛8

r = 2

Since we know a and r, find the 2nd and 3rd which are represented by x and y respectively, by applying an = ar^(n - 1):

a2 = 5 * 2^(2 - 1)

a2 = 5 * 2^1

a2 = 10

x = 10

a3 = 5 * 2^(3 - 1)

a3 = 5 * 2²

a3 = 20

y = 20
