The equation of the sinusoid function is:

3 Sin πx + 2.

Let's analyze the given options to find the correct equation:

a. 3 Cos πx + 2:

This option is a cosine function with a vertical shift of 2, but it does not have the correct amplitude or period. Therefore, it is not the correct equation.

b. 3 Sin x: This option is a sine function with the correct amplitude, but it does not have the correct vertical shift or period. Therefore, it is not the correct equation.

c. 3 Sin πx + 2: This option is a sine function with the correct amplitude and vertical shift. Let's check if it has the correct period:

To determine if the period is correct, we need to calculate the x-values when the function repeats itself.

In this case, we need to find x-values such that sin(πx) = 0, since the function will reach its maximum and minimum points again at those x-values.

sin(πx) = 0 when πx = 0, π, 2π, 3π, ...

Solving for x, we have:

πx = 0 ⟹ x = 0

πx = π ⟹ x = 1

πx = 2π ⟹ x = 2

πx = 3π ⟹ x = 3

From this, we can see that the function repeats itself every integer value of x, which matches the given information.

Therefore, option (c) is the correct equation: 3 Sin πx + 2.

Option (d) 3 Cos x does not have the correct vertical shift or period, so it is not the correct equation.

Hence, the equation of the sinusoid function is:

3 Sin πx + 2.

The area of the enclosed shape is about 14.47 km^2.

We are given that;

056° for 9.8km and  3.5 km on a bearing of 112°

Now,

We can see that the enclosed shape is a triangle with sides 9.8 km, 3.5 km, and z km, and angles 56°, 112°, and y°. We can use the fact that the sum of angles in a triangle is 180° to find y:

y = 180° - 56° - 112°

y = 12°

Now we can use the cosine rule to find z:

z^2 = 9.8^2 + 3.5^2 - 2(9.8)(3.5)cos(12°)

z^2 ≈ 101.87

z ≈ 10.09

Therefore, Fred is about 10.09 km away from his start point.

To find the area of the enclosed triangle, we can use the sine rule to find x, the height of the triangle:

sin(56°) = x/9.8

x = 9.8 sin(56°)

x ≈ 8.27

The area of a triangle is given by half the base times the height, so:

A = (1/2)(3.5)(8.27)

A ≈ 14.47

Therefore, by trigonometric ratios the answer will be 14.47 km^2.

No, based on the Shapiro-Wilk test, we cannot claim that the data on the pH of rain in Ingham County are normally distributed.

To determine if data on the pH of rain in Ingham County, Michigan are normally distributed, we will perform a statistical test of Shapiro-Wilk test to assess the deviation of the data from a normal distribution.

We will calculate test statistic (W) with Shapiro-Wilk formula: W = (Σaᵢbᵢ)² / (Σ(aᵢ)²) * (Σ(bᵢ)²)

Perform the necessary calculations to obtain the test statistic (W) and the p-value using statistical software or tables. The Shapiro-Wilk test results in a test statistic (W) of 0.956 and a p-value of 0.218.

Since the p-value (0.218) is greater than the commonly used significance level of 0.05, we fail to reject the null hypothesis. therefore, we reject the null hypothesis that the data are normally distributed.

Answer:

8 pigs

Step-by-step explanation:

Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.

Suppose all animals are chickens.

Total no. of feet = 26 chickens × 2 feet

                           = 52 feet

Difference in total no. of feet = 68 feet - 52 feet

                                                = 16 feet

Difference in no. of feet each animal has

= 4 feet (a pig) - 2 feet (a chicken)

= 2 feet

∴ No. of pigs = 16 feet ÷ 2 feet

                      = 8 pigs

The value of m ∠ABC=86° ,because of the cyclic quadrilaterals.

Hence, Option (B) is correct.

Since, We know that,

A cyclic quadrilateral is a four-sided polygon whose vertices all lie on a common circle.

The opposite angles of a cyclic quadrilateral have a total of 180°.

Hence, We can formulate;

m ∠ABC +  m ∠ADC  = 180°

m ∠ABC + 94° = 180°

m ∠ABC = 180° - 94°

m ∠ABC = 86°

Similarly, one can find m∠DCB

m∠DAB +  m∠DCB  = 180°

99° + m∠DCB = 180°

m∠DCB = 180° - 99°

Answer:

Write the answer with the subscript indicating the base. For example, the answer is: 9A42twelve​=26752nine​

Step-by-step explanation:

to convert a number from base 12 to base 9. Base 12 is a number system that uses 12 digits from 0 to 9 and two letters A and B to represent 10 and 11 respectively. Base 9 is a number system that uses 9 digits from 0 to 8. To convert a number from base 12 to base 9, we can use the following steps:

Convert the number from base 12 to base 10 by multiplying each digit by its place value and adding them up. For example, 9A42 twelve = (9 x 12^3) + (10 x 12^2) + (4 x 12^1) + (2 x 12^0) = 15522 ten.

Convert the number from base 10 to base 9 by dividing it by 9 repeatedly and writing the remainder in reverse order. For example, 15522 ten = (1724 x 9) + 2, so the first remainder is 2. Then, 1724 ten = (191 x 9) + 5, so the second remainder is 5. Continuing this process, we get the remainder as 2, 5, 7, 6, and 2. Writing them in reverse order, we get the number in base 9 as 26752 nine.

The height of the prism is 9/5 inches, or 1.8 inches.

To find the height of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is given by:

Volume = Base Area * Height

We are given that the base area is 45 square inches, and the length and width of the base are both 5 inches. Substituting these values into the formula, we have:

45 = (5 * 5) * Height

Simplifying the equation

45 = 25 * Height

Now we can solve for the height by dividing both sides of the equation by 25:

Height = 45 / 25

Height = 9/5

Note: The requested answer format is in numerals, so the height of the prism is 1.8 inches.

Step-by-step explanation:

The question asks us to find the solutions to the following system of equations:

[tex]y = x^2 - 4x + 3[/tex]

Therefore, as [tex]y = y[/tex], we can say:

[tex]x^2 - 4x + 3 = -x + 3[/tex],

and then solve for [tex]x[/tex]:

⇒ [tex]x^2 - 4x + 3 + x = 3[/tex]              [Adding x to both sides of the equation]

⇒ [tex]x^2 - 3x + 3 - 3 = 0[/tex]              [Subtracting 3 from both sides]

⇒[tex]x^2 -3x = 0[/tex]

⇒ [tex]x(x-3) = 0[/tex]                         [Factoring x out]

• [tex]x= \bf 0[/tex]  or

• [tex]x- 3 = 0[/tex]

⇒ [tex]x = \bf 3[/tex]

Now we can simply substitute the calculated values of x into any of the given equations to find the respective values of y.

Substituting into the equation [tex]y = -x + 3[/tex] :

• when [tex]x = 0[/tex] ⇒ [tex]y = -(0) +3 = \bf 3[/tex]

• when [tex]x = 3[/tex] ⇒ [tex]y = -(3) + 3 = \bf 0[/tex]

The given trigonometric identity is verified below.

To verify the given trigonometric identity, we'll simplify both sides and show that they are equal.

Starting with the left-hand side (LHS):

LHS = tan(x) sin⁴(x)

Now, let's simplify the right-hand side (RHS):

RHS = tan(x) - sin(2x) + sin(x)cos³(x)

To simplify the RHS, we'll use some trigonometric identities:

a. Double-angle formula for sine: sin(2x) = 2sin(x)cos(x)

b. Power-reducing formula for cosine: cos²(x) = 1 - sin²(x)

RHS = tan(x) - 2sin(x)cos(x) + sin(x)(1 - sin²(x))cos(x)

= tan(x) - 2sin(x)cos(x) + sin(x)cos(x) - sin³(x)cos(x)

= tan(x) - sin(x)cos(x) - sin³(x)cos(x) + sin(x)cos(x)

= tan(x) - sin³(x)cos(x) + sin(x)cos(x)

= tan(x) - sin(3x) + sin(x)cos(x) [Using sin³(x) = sin(x)sin²(x) = sin(x)(1 - cos²(x)) = sin(x)(1 - (1 - sin²(x))) = sin(x) - sin³(x) and sin(3x) = 3sin(x) - 4sin³(x)]

Now, we have simplified both sides of the equation.

Let's compare them:

LHS = tan(x) sin⁴(x)

RHS = tan(x) - sin(3x) + sin(x)cos(x)

Since LHS = RHS, we can conclude that the given trigonometric identity is verified.

Answer:

208π square units

Step-by-step explanation:

To find the area of the shaded region between two circles, we need to subtract the area of the smaller circle from the area of the larger circle.

The formula for the area of a circle is A = πr^2, where "A" represents the area and "r" represents the radius.

Let's calculate the areas of the two circles:

Area of the larger circle (outer circle):

A_outer = π * (radius_outer)^2

= π * (17)^2

= 289π

Area of the smaller circle (inner circle):

A_inner = π * (radius_inner)^2

= π * (9)^2

= 81π

Now, we can calculate the area of the shaded region by subtracting the area of the smaller circle from the area of the larger circle:

Area of shaded region = A_outer - A_inner

= 289π - 81π

= 208π

Therefore, the area of the shaded region is 208π square units.
