Answer:

91.1cm²

Step-by-step explanation:

since all of them are quarters of circles

area of figure 1 = (π(r.1)²)÷4 = (64π)÷4= 16π cm²

area of figure 2 = (π(r.2)²)÷4 = (25π)÷4= 6.25π cm²

area of figure 3 = (π(r.3)²)÷4 = (9π)÷4= 2.25π cm²

area of figure 4 = (π(r.4)²)÷4 = (4π)÷4= 4π cm²

area of figure 5 = (π(r.5)²)÷4 = (π)÷4 cm²

area of figure 6 = (π(r.6)²)÷4 = (π)÷4 cm²

the total area = 16π+6.25π+2.25π+4π+2(π÷4)=

28.5π+0.5π = 29π = 91.1cm²

Step-by-step explanation:

y = 37 + x

the 4th angle (bottom right) is

360 - 90 - 90 - 125 = 55°

because the sum of all angles in any quadrilateral is 360°.

now we can assume a right-angled triangle on the right side of the trapezium.

one leg is 15 cm (like the left side), the other leg is x cm. and the right side of the trapezium is the Hypotenuse.

the bottom right angle is 55°.

the upper angle is 125 - 90 = 35°.

we can use the law of sine to get x.

the law of sine is

a/sin(A) = b/(sin(B) = c/sin(C)

with a, b, c being the sides of the triangle opposite of the corresponding angles A, B, C.

so,

15/sin(55) = x/sin(35)

x = 15×sin(35)/sin(55) = 10.50311307... cm

y = 37 + 10.50311307... = 47.50311307... ≈

≈ 47.5 cm

Therefore ,as a result, 42/5 is the value of the first term in the equation for the arithmetic mean.

The arithmetic average or means of the group is calculated as the sum of each value in a list divided by the total number of things in that list. The progression in mathematics is the same as this. The average of the integers 5, 7, and 9 is 4, as shown by the equation 5 + 7 + 9 being equal to 21, and 21 divided by 3 (there are actually three numbers) being equal to 7.

Here,

Given :

5 a + 10 d = 70 in the first five terms (1)

The first ten terms add up to 10 a + 45 d = 210. (2)

This means that in order to solve the system for a, multiply equation (1) by 2, then subtract it from equation (2):

=> 10a - 10a + 45d - 20d = 210-140

=> 25d = 70

=> d = 70/25

=> d = 14/5

A value then becomes:

5a + 10*14/5 = 70;

5a = 70-140/5;

5a = 350-140/5;

a = 42/5.

42/5 is the response.

As a result, 42/5 is the value of the first term in the equation for the arithmetic mean.

a) Pour déterminer le solde du compte au bout de 3 ans, nous devons utiliser la formule de l'annuité de fin de période. Il y a un total de 3 ans x 12 mois/an = 36 mois de capitalisation. Le taux d'intérêt par mois est de 6%/12 = 0.005. La somme déposée chaque mois est de 100 $. En utilisant la formule, nous pouvons calculer le solde final:

M = (R[(1 + i)^n −1])/i

M = (100 [(1 + 0.005)^36 −1])/0.005 = $51,664.23

b) Pour calculer le total de l'intérêt accumulé, nous pouvons soustraire le montant total des dépôts (100 $ x 36 mois = $3,600) au solde final du compte.

Intérêt accumulé = Solde final du compte - Montant total des dépôts

Intérêt accumulé = $51,664.23 - $3,600 = $48,064.23

One possible solution is to have Cameron buying 18 candies and 6 drinks, this solution is (6,18) and it lies in the intersection of all three half-planes.

We can write a system of inequalities to represent the situation as follows:

6x + 5y ≥ 90 (because Cameron must spend at least $90 on drinks and candies)

x + y ≥ 18 (because Cameron must buy at least 18 drinks and candies altogether)

x ≥ 0, y ≥ 0 (because Cameron can't buy negative number of drinks or candies)

To graphically represent the solution set of this system, we can plot the inequalities on a coordinate plane. We can start by drawing the line representing the first inequality: 6x + 5y = 90. To find the slope-intercept form of this equation we can subtract 90 from both sides, 6x + 5y - 90 = 0, and we get: 6x + 5y = 90.

The second inequality is x + y ≥ 18 which is a boundary line.

The third inequality is x ≥ 0 and y ≥ 0 which means that both x and y should be non-negative.

The solution set of this system of inequalities is the intersection of the half-planes defined by the inequalities. This is the set of all points that lie in all three half-planes. One possible solution is to have Cameron buying 18 candies and 6 drinks, this solution is (6,18) and it lies in the intersection of all three half-planes.

The gradient of f(x, y, z) = log(x2 + y2 + z2) at (1, 0, 1) is (2/1, 0, 2/1).

This gradient is a vector pointing in the direction of the function f(x, y, z) = log(x2 + y2 + z2 )'s rate of growth. Calculating the function's partial derivatives with respect to x, y, and z is necessary to assess this gradient.

The function's partial derivative with regard to x is (2x / (x2 + y2 + z2) This becomes 2/1 when x is 1. The partial derivative with regard to z is (2z / (x2 + y2 + z2)), which becomes 2/1 when z is 1, and the partial derivative with respect to y is 0, and the partial derivative with respect to z is 0, respectively. Therefore, at (1, 0, 1), the gradient of f(x, y, z) = log(x2 + y2 + z2) is (2/1, 0, 2/1).

To find the general solution of the given differential equation x dy/ dx − y = x^2 sin x, we must use a series of calculations.

First, we need to separate the variables, so y can be expressed as a function of x. To do this, we divide both sides of the equation by x, giving us the equation dy/dx = x sin x + y/x.

Next, we will need to use integration to find the general solution. To integrate, we need to find an antiderivative of the equation dy/dx = x sin x + y/x. To do this, we can use the formula ∫xdx = 1/2 x^2 + c. Using this formula, we can integrate both sides of the equation to get 1/2 x^2 + c = x sin x + ∫ y/x dx.

We can then solve for the antiderivative of y/x, which is ln|y| + c. Therefore, the general solution of the equation is 1/2 x^2 + ln|y| + c = x sin x + c.

Finally, we can solve for y in terms of x to get y = x^2 sin x + c'e^(1/2 x^2), where c' is the integration constant. This is the general solution of the given differential equation.
