Step-by-step explanation:

The slant height of the square base pyramid is calculated as l = 17 using the Pythagoras rule.

The Pythagoras rule states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. 

we can observe the right triangle with hypotenuse l, height = 15, and base = 8 {half the pyramid base of 16}

the slant height is calculated as follows:

l² = 15² + 8²

l² = 225 + 64

l² = 289

l = √289 {take square root of both sides}

l = 17.

Therefore, the slant height of the square base pyramid is calculated as l = 17 using the Pythagoras rule.

Answer:

y = 4x + 32

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 4x ← is in slope- intercept form

with slope m = 4 and y- intercept = 0

• Parallel lines have equal slopes , then

y = 4x + c ← is the partial equation

to find c substitute (- 8, 2 ) into the partial equation

2 = 4(- 8) + c = - 32 + c ( add 32 to both sides )

34 = c

y = 4x + 32 ← in slope- intercept form

Answer: The equation "x + y = mb" represents a linear equation in two variables, x and y. In this equation, m is a constant and b is another constant or a known value. The equation states that the sum of x and y is equal to the product of m and b.

This equation can be used to model a variety of real-world situations where two quantities are related and their sum is equal to a constant value. For example, it could represent the amount of money saved by two people, where x and y are the savings of the two people and mb is the total amount of money saved.

To solve for x and y, we can use either substitution or elimination method, or any other method for solving systems of linear equations. The values of x and y that satisfy the equation "x + y = mb" are called the solutions of the equation.

Step-by-step explanation:

The length of the arc that the tip of the pendulum travels is approximately 7 feet.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

We can use the formula for the length of an arc of a circle to find the length of the arc that the tip of the pendulum travels:

Arc length = (angle/360) x 2πr

where: angle = the central angle (in degrees or radians) that the arc subtends and r = the radius of the circle

First, we need to convert the angle from degrees and minutes to decimal degrees.

There are 60 minutes in a degree, so:

40°6' = 40 + 6/60 = 40.1 degrees

Now we can plug in the values:

Arc length = (40.1/360) x 2π(10 feet)

Arc length = 6.99 feet

Hence, the length of the arc that the tip of the pendulum travels is approximately 7 feet.

Answer: Since the speed of personal computers is expected to double every 18 months, we can use exponential growth to calculate the increase in speed over time. We can start by finding the growth factor, which is equal to 2 raised to the power of the number of doublings. In this case, the number of doublings over 6 years can be calculated as follows:

6 years / 1.5 years = 4 doublings

So the growth factor is:

2^4 = 16

This means that the speed of personal computers will be 16 times faster in 6 years compared to now.

The set of all numbers less than 17 and greater than or equal to -8 can be expressed in set builder notation as:

{x | -8 <= x < 17}

Step-by-step explanation:

Set builder notation is a way of expressing a set of elements in mathematical terms. The syntax of set builder notation is {x | <condition>}, where x represents an element in the set and the condition specifies the properties that the element must satisfy to be included in the set.

In this case, the set consists of all numbers less than 17 and greater than or equal to -8. The condition for the set is -8 <= x < 17, where x is a real number. This means that x must be greater than or equal to -8 and less than 17 in order to be included in the set.

Therefore, the set of all numbers less than 17 and greater than or equal to -8 can be expressed in set builder notation as:

{x | -8 <= x < 17}.

The exact perimeter of the segment is 54.13 inches, and the exact area of the segment is 301.44 square inches.

What is perimeter and area enclosed in circle?

A circle is also defined by two properties: area and perimeter. The formulas for both the measures of the circle are given by; Area of a circle = πr². The perimeter of a circle = 2πr.

Let's call the center of the circle O and the endpoint of the arc A. Let's also call the endpoint of the chord that defines the segment B. Then we have an isosceles triangle OAB, where OA = OB = 24 inches.

1) The perimeter of the segment is equal to the length of the arc plus the length of the chord. To find the length of the arc, we can use the formula:

Arc length = (Ф / 360) * 2πr,

where Ф is the measure of the angle in degrees, r is the radius (which is 24 inches in this case), and π is pi.

In this case, the measure of the angle is 60°, so the length of the arc is:

Arc length = (60 / 360) * 2π * 24 inches

Arc length  = (1/6) * 2π * 24 inches

Arc length  = 4π inches

To find the length of the chord, we can use the formula:

Chord length = 2r * sin(Ф/2), where r is the radius and Ф is the measure of the angle in radians.

First, we need to convert the angle measure from degrees to radians:

60° = 60 * (π / 180) radians = π / 3 radians

Now, we can find the length of the chord:

Chord length = 2 * 24 * sin(π / 6)

Chord length = 24 * 2 * sin(π / 6)

Chord length = 24 * √3 inches

Finally, we can add the length of the arc and the chord to find the perimeter:

Perimeter = 4π + 24 * √3

Perimeter = 4π+41.57

Perimeter = 54.13 inches

2) To find the area of the segment, we can use the formula:

Area = (Ф/ 360) * πr², where Ф is the measure of the angle in degrees and r is the radius.

In this case, the measure of the angle is 60°, so the area of the segment is:

Area = (60 / 360) * π * 24² square inches

Area = (1/6) * π * 576 square inches

Area = 96π square inches

Area = 301.44 square inches

So, The exact perimeter of the segment is 54.13 inches, and the exact area of the segment is301.44 square inches.

Answer:

Let's call angle d₁ "θ". To find θ, we can use the Pythagorean theorem. The segment AO is the hypotenuse of a right triangle with sides BC/2 and AC/2 (since the rhombus is a parallelogram, opposite sides are equal).

AC/2 = (BC/2) / tan(θ)

So:

tan(θ) = AC/2 / (BC/2)

Plugging in the values we have:

tan(θ) = 3.8 / (5/2) = 3.8 / 2.5 = 1.52

Therefore,

θ = tan^(-1)(1.52) = 55.23°

The tangent ratio of angle c₂ is simply the tangent of the angle:

tan(c₂) = tan(90° - θ) = tan(90° - 55.23°) = tan(34.77°) = 1.52

So the tangent ratio of angle c₂ is 1.52.

Step-by-step explanation:

To find the distance from a point P to a plane defined by three points Q, R, and S, we can use the following formula:

distance = |(A * x + B * y + C * z + D) / √(A^2 + B^2 + C^2)|

where (A, B, C) are the coefficients of the normal vector of the plane, (x, y, z) are the coordinates of the point P, and D is the constant in the equation of the plane.

To find the coefficients of the normal vector, we can use the cross product of two vectors lying in the plane, say, QR and RS.

Let's first find the vectors QR and RS:

QR = (5 - 0, 0 - (-1), 3 - 7) = (5, 1, -4)

RS = (7 - 0, 5 - (-1), 0 - 7) = (7, 6, -7)

Next, we find the cross product of QR and RS:

cross product of QR and RS = (B, C, A) = (7, -30, 15)

So, the normal vector of the plane is (15, -30, 7).

Now we substitute the values for the coefficients and the coordinates of the point P into the formula:

distance = |(15 * 3 + (-30) * 1 + 7 * 7 + D) / √(15^2 + (-30)^2 + 7^2)|

To find the value of D, we can use any of the three points on the plane and substitute their coordinates into the equation of the plane in the form Ax + By + Cz + D = 0.

Let's use the point Q:

15 * 5 + (-30) * 0 + 7 * 3 + D = 0

Expanding and solving for D, we get:

75 + 21 + D = 0

D = -96

Finally, substituting the values back into the formula for distance, we get:

distance = |(15 * 3 + (-30) * 1 + 7 * 7 + -96) / √(15^2 + (-30)^2 + 7^2)|

distance = |(-24 + -30 + 49 - 96) / √(15^2 + (-30)^2 + 7^2)|

distance = |(-101) / √(15^2 + (-30)^2 + 7^2)|

distance = |(-101) / √(15^2 + (-30)^2 + 7^2)|

distance = |(-101) / √(225 + 900 + 49)|

distance = |(-101) / √1274|

distance = |(-101) / 35.6|

distance = 2.85

So, the distance between the point P and the plane is approximately 2.85.
