Explanation:

If angle A is 43 degrees, then minor arc BC is 2*43 = 86 degrees according to the inscribed angle theorem. The central angle is twice that of the inscribed angle. Both of these angles subtend the same minor arc.

When I say "minor arc BC", I mean that we go from B to C along the shortest path. Any minor arc is always less than 180 degrees.

Since minor arc AB is 69 degrees, and minor arc BC is 86 degrees, this means arc ABC is arcAB+arcBC = 69+86 = 155 degrees

Let's say point D is some point on the circle that isn't between A and B, and it's not between B and C either. Refer to the diagram below. The diagram is to scale. The diagram your teacher provided is not to scale because arc ABC is way too big (it appears to be over 180 degrees). Hopefully the diagram below gives you a better sense of what's going on.

Because arc ABC = 155 degrees, this means the remaining part of the circle, arc ADC, is 360-(arc ABC) = 360-155 = 205 degrees

Inscribed angle B subtends arc ADC. So we'll use the inscribed angle theorem again, but this time go in reverse from before. We'll cut that 205 degree angle in half to get 205/2 = 102.5 degrees which is the measure of angle B. This value is exact. In this case, we don't need to apply any rounding.

Answer:

0.5%

Step-by-step explanation:

The prevalence rate shows the proportion of people that have a disease in a population and to be able to calculate it, you have to divide the number of people that have a disease by the population:

Prevalence rate=(5/1,000)*100

Prevalence rate=0.005*100

Prevalence rate=0.5%

According to this, the answer is that if there are five cases of H1N1 in the community of 1,000 people, the prevalence rate is 0.5%.

Volume of my ice cream will be;

⇒ The volume of cone = 4.25 inches³

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The height of the cone is 4 5/8 inches.

And, The diameter is 1 7/8 inches.

Now,

Since, The height of the cone = 4 5/8 inches.

                                              = 37/8 inches

And, The diameter = 1 7/8 inches.

                             = 15/8 inches

Hence, The radius of cone = 15/8 ÷ 2

                                         = 15/16 inches

Here, The volume of cone = πr²h / 3

Substitute all the values, we get;

The volume of cone = πr²h / 3

                               = π × (15/16)² × 37/8 × 1/3

                               = 4.25 inches³

tan(41π/36) can be written in terms of the tangent of a positive acute angle as (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

To express tan(41π/36) in terms of the tangent of a positive acute angle, we need to find an angle within the range of 0 to π/2 that has the same tangent value.

First, let's simplify 41π/36 to its equivalent angle within one full revolution (2π):

41π/36 = 40π/36 + π/36 = (10/9)π + (1/36)π

Now, we can rewrite the angle as:

tan(41π/36) = tan((10/9)π + (1/36)π)

Next, we'll use the tangent addition formula, which states that:

tan(A + B) = (tan(A) + tan(B)) / (1 - tan(A)tan(B))

In this case, A = (10/9)π and B = (1/36)π.

tan(41π/36) = tan((10/9)π + (1/36)π) = (tan((10/9)π) + tan((1/36)π)) / (1 - tan((10/9)π)tan((1/36)π))

Now, we need to find the tangent values of (10/9)π and (1/36)π. Since tangent has a periodicity of π, we can subtract or add multiples of π to get equivalent angles within the range of 0 to π/2.

For (10/9)π, we can subtract π to get an equivalent angle within the range:

(10/9)π - π = (1/9)π

Similarly, for (1/36)π, we can add π to get an equivalent angle:

(1/36)π + π = (37/36)π

Now, we can rewrite the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Since we are looking for an angle within the range of 0 to π/2, we can further simplify the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Therefore, tan(41π/36) can be written in terms of the tangent of a positive acute angle as the expression given above.

Step-by-step explanation:

The gradient of the function \(\(f\)\) at the point \(\((-1, -3)\)\) is:

\(\[\nabla f(-1, -3) = \left(-3e^{-3} \sin(12), 4e^{-3} \cos(12)\right)\]\)

To find the gradient of the function \(\( f(x, y) = e^{3x} \sin(4y) \)\) at the point \(\((-1, -3)\)\), we need to compute the partial derivatives with respect to \(\(x\) and \(y\)\) and evaluate them at that point.

The gradient of a function is given by:

\(\[\nabla f(x, y) = \left(\frac{{\partial f}}{{\partial x}}, \frac{{\partial f}}{{\partial y}}\right)\]\)

Let's calculate the partial derivatives:

\(\[\frac{{\partial f}}{{\partial x}} = \frac{{\partial}}{{\partial x}}\left(e^{3x} \sin(4y)\right) = 3e^{3x} \sin(4y)\]\)

\(\[\frac{{\partial f}}{{\partial y}} = \frac{{\partial}}{{\partial y}}\left(e^{3x} \sin(4y)\right) = 4e^{3x} \cos(4y)\]\)

Now, we can evaluate these derivatives at the point \(\((-1, -3)\):\)

\(\[\frac{{\partial f}}{{\partial x}}\Bigr|_{(-1, -3)} = 3e^{3(-1)} \sin(4(-3)) = 3e^{-3} \sin(-12)\]\)

\(\[\frac{{\partial f}}{{\partial y}}\Bigr|_{(-1, -3)} = 4e^{3(-1)} \cos(4(-3)) = 4e^{-3} \cos(-12)\]\)

Simplifying further:

\(\[\frac{{\partial f}}{{\partial x}}\Bigr|_{(-1, -3)} = 3e^{-3} \sin(-12) = -3e^{-3} \sin(12)\]\)

\(\[\frac{{\partial f}}{{\partial y}}\Bigr|_{(-1, -3)} = 4e^{-3} \cos(-12) = 4e^{-3} \cos(12)\]\)

Therefore, the gradient of the function \(\(f\)\) at the point \(\((-1, -3)\)\) is:

\(\[\nabla f(-1, -3) = \left(-3e^{-3} \sin(12), 4e^{-3} \cos(12)\right)\]\)

The proof of  \(\lim_{z \to i}\) (3z⁴ - 2z³ + 8z² - 2z + 5)/(z - i) = 4+4i, by using L-Hopital Rule is explained below.

We have to prove that, the limit for the function (3z⁴ - 2z³ + 8z² - 2z + 5)/(z - i) is 4i+4,

\(\lim_{z \to i}\) (3z⁴ - 2z³ + 8z² - 2z + 5)/(z - i);

On substituting z=i, we get 0/0 form,

So, we apply L-Hopital Rule, that is  we differentiate the numerator and denominator with respect to "z"

We get,

\(\lim_{z \to i}\) (d/dz(3z⁴ - 2z³ + 8z² - 2z + 5))/d/dz(z - i),

\(\lim_{z \to i}\) (12z³ - 6z² + 16z - 2)/1,

Substituting z=i,

We get,

= (12(i)³ - 6(i)² + 16(i) - 2),

= -12i + 6 + 16i - 2,

= 4i + 4,

Answer:

\(\frac{3b}{a} = 210\)

Step-by-step explanation:

Explanation:-

Given that  a× 70 = b

Dividing 'a' into both sides, we get

           ⇒ \(\frac{b}{a} = 70\)

we have to find the value \(\frac{3b}{a}\)

       \(\frac{3b}{a} = 3 X \frac{b}{a}\)

          = 3× 70

         = 210

The largest interval I over which the solution is defined is:

I = (9 - ∞, 9 + ∞)

To solve the given initial-value problem, we need to rearrange the equation and separate the variables. The equation can be rearranged as follows:

y dx = (3y^2 + x) dy

Next, we need to separate the variables and integrate both sides of the equation:

∫y dx = ∫(3y^2 + x) dy

∫y dx = y^3 + xy + C

Now, we can use the initial condition x(9) = 1 to solve for C:

1 = 9^3 + 9(1) + C

C = -729

Therefore, the solution to the initial-value problem is:

y^3 + xy = 729

To find the largest interval I over which the solution is defined, we need to determine the values of x and y that make the equation true. Since the equation is a cubic equation, there are potentially three solutions for y. However, since we are looking for the largest interval, we only need to find the smallest and largest values of y that satisfy the equation. These values will be the endpoints of the interval I.

The smallest value of y occurs when x is at its largest value, which is infinity. Plugging in x = ∞ and solving for y gives us:

y^3 + ∞y = 729

y^3 = 729 - ∞y

y = 729^(1/3) - ∞^(1/3)

y = 9 - ∞

The largest value of y occurs when x is at its smallest value, which is negative infinity. Plugging in x = -∞ and solving for y gives us:

y^3 - ∞y = 729

y^3 = 729 + ∞y

y = 729^(1/3) + ∞^(1/3)

y = 9 + ∞

Therefore, the largest interval I over which the solution is defined is:

I = (9 - ∞, 9 + ∞)

These six different iterated integrals represent the same volume integral but with different orders of integration.

To express the integral ∭ef(x,y,z)dv as an iterated integral in six different ways, where e is the solid bounded by

z=0, x=0, z=y-4x,

and y=12, we first determine the limits of integration for each variable. The solid is bounded by the following planes:

z = 0 (lower limit for z)
x = 0 (lower limit for x)
z = y - 4x (upper limit for z)
y = 12 (upper limit for y)

Now, we can write the iterated integral in six different orders of integration:

dx dy dz:
∭ef(x,y,z)dv = ∫(0 to 12)∫(0 to y/4)∫(0 to y-4x) ef(x,y,z) dz dx dy

dx dz dy:
∭ef(x,y,z)dv = ∫(0 to 12)∫(0 to y-4x)∫(0 to y/4) ef(x,y,z) dx dz dy

dy dx dz:
∭ef(x,y,z)dv = ∫(0 to 12)∫(0 to y/4)∫(0 to y-4x) ef(x,y,z) dz dy dx

dy dz dx:
∭ef(x,y,z)dv = ∫(0 to 12)∫(0 to y-4x)∫(0 to y/4) ef(x,y,z) dy dz dx

dz dx dy:
∭ef(x,y,z)dv = ∫(0 to 12)∫(0 to y/4)∫(0 to y-4x) ef(x,y,z) dx dy dz

dz dy dx:
∭ef(x,y,z)dv = ∫(0 to 12)∫(0 to y-4x)∫(0 to y/4) ef(x,y,z) dy dx dz
