The vertical component of velocity can be zero at specific points in the motion of an object.

What is Velocity?

Velocity is a vector quantity that describes the rate of change of an object's position in space over time. It is defined as the displacement of an object divided by the time interval during which the displacement occurred.

The vertical component of velocity can be zero at specific points in the motion of an object. This occurs when the object reaches the highest point in its vertical motion and begins to fall back down. At this point, the vertical component of velocity changes direction from upward to downward, and its magnitude becomes zero. This moment is known as the "instant of maximum height" or "instant of maximum altitude." Beyond this point, the vertical component of velocity becomes negative, indicating that the object is moving downward.

Area of the shaded figure is 77.7 square unit (rounded to 1 decimal place).

EXPLANATION

Given:

Rectangle with length = 12 and breadth = 7.

Semi-Circle with diameter = 4

Desired Outcome:

The area of the shaded region.

Looking at the figure carefully, you will notice that it was only half of the circle that was fixed with the rectangle.

Determine the Area of a semi-circle

Area of a semi-circle is half of the area of a circle

Area of the Rectangle

Determine the area of the shaded figure

Hence, the Area of the shaded figure is 77.7 square unit (rounded to 1 decimal place).

The coordinates of the specified vertex after the given sequence of transformations is given by;

Q' = (3, -3).

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated up simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image or parent function.

Mathematically, a horizontal translation to the right is modeled by this mathematical expression g(x) = f(x + N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.

Where:

By translating the coordinate Q (1, 3) two (2) units to the right, we have the following:

Coordinate Q (1, 3) → Coordinate Q' (1 + 2, 3) = Q (3, 3)

In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection over the x-axis is given by this transformation rule:

(x, y)      →       (x, -y)

Coordinate Q' (3, 3) → (3, -3).

The limit to the above question is 0.

The value that a function approaches when its input value approaches a certain value is known as a limit in mathematics.

To evaluate the limit:

We can use L'Hopital's rule. Taking the derivative of the numerator and denominator with respect to x:

lim x→0 (1 - cos x / x) = lim x→0 [(sin x) / 1]

= sin(0)

= 0

Therefore, the limit is 0.

The solution is, the volume of Pyramid with the given base and height is found as:  2342.925 sq. km.

Explain about the shape of Pyramid:

A pyramid is just a polyhedron with a polygonal base and triangles on all of its lateral faces. In this lesson, we will only focus on pyramids with lateral faces that are congruent, or identical in size and shape.

The base of a pyramid is often used to describe the structure.

A hexagonal pyramid has to have a base that is a hexagon, while a triangular pyramid seems to have a base that is a triangle.

Given data:

Base length = 26.7 km

base width = 11.7 km

Height = 15 km

Volume of Pyramid:

V = base area * height

Base area = 1/2*base*height

Base area = 1/2*26.7*11.7

Base area =  156.195 sq.km.

Now,

Volume of Pyramid =  156.195 * 15

Volume of Pyramid =  2342.925 sq. km.

Thus, the volume of Pyramid with the given base and height is found as:

Let the no. of weeks be x. Then,

Amount collected by savings = $40x

So, The equation will be:

➝ 125 + 40x = 600

Note:

The range of the function g(x) is [300, ∞)

In this question, we have been given that we have deposited $300 into a savings account that earns interest annually.

The function g(x) = 300(1.04)^x used to find the amount of money in the savings account, g(x), after x years.

We need to find the range of the function.

Since a savings account earns interest annually, x can have take values from 0 to infinity.

For x = 0 year,

g(0) = 300(1.04)^0

g = 300 * 1

g = 300

For x tends to ∞, the value of function would be ∞

Therefore, the range of the function g(x) is [300, ∞)

In order to know if a triangle is a right triangle on a coordinate plane, you can find the lengths of all three sides of the triangle using the distance formula and apply the Pythagorean theorem.

Find the lengths of the three sides of the triangle using the distance formula.

Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.

If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.

The expansion of (1+x)^n has three consecutive coefficients that satisfy a : b : c.

To find the expansion of (1+x)^n, we can use the binomial theorem. According to the theorem, the coefficients of the expanded expression are given by the binomial coefficients, which can be calculated using the formula C(n,k) = n! / (k!(n-k)!), where n is the power of the binomial and k represents the term number.

Now, to find three consecutive coefficients that satisfy a : b : c, we need to look for a pattern in the binomial coefficients. Since we are given that a, b, and c are consecutive, we can express them as C(n,k), C(n,k+1), and C(n,k+2).

To find the pattern, we can divide each coefficient by the previous one. If a : b : c, then (C(n,k+1) / C(n,k)) = (C(n,k+2) / C(n,k+1)). Simplifying this expression, we get (k+1) / (n-k) = (k+2) / (n-k-1).

By solving this equation, we can determine the values of k and n that satisfy the given condition, and thus find the three consecutive coefficients a, b, and c.

The comparison of the expressions is 7 + 3² -2  * 5 ÷ 4 - 1 * 2 > (¾+ ⅛) ÷ ⅛ - 2²

From the question, we have the following parameters that can be used in our computation:

7 + 3^2-2x5÷4-1x2 and (¾+ ⅛) ÷ ⅛ - 2^2

Express the exponents properly

This gives

7 + 3² -2  * 5 ÷ 4 - 1 * 2 and (¾+ ⅛) ÷ ⅛ - 2²

Evaluate the exponents

So, we have the following representation

7 + 9 - 2 * 5 ÷ 4 - 1 * 2 and (¾+ ⅛) ÷ ⅛ - 4

Evaluate the expressions in brackets

So, we have the following representation

7 + 9 - 2 * 5 ÷ 4 - 1 * 2 and 7/8 ÷ ⅛ - 4

Solve the products and quotients

7 + 9 - 2.5 - 2 and 7 - 4

The equation could be used to solve for charles' rate if it is represented by x is 2x=54.

In the given question wehave to find the equation could be used to solve for charles' rate if it is represented by x.

Bill riding a bicycle at an average rate of 9 mph.

Charles' rate is x.

So the relative rate = x−9 mph

Distance traveled by Bill in 4 hours = 9*4 =36 mph

Charles' overtook Bill in 2 hours. So

Relative Rate = Distance/Time

x−9=36/2

Multiply by 2 on both side. We get

2(x−9)=36

Simplifying

2x−18=36

Add 18 on both side, we get

2x=36+18

2x=54

Hence, the equation could be used to solve for charles' rate if it is represented by x is 2x=54.

The measure of the minor arc intercepted by the inscribed angle is 228 degrees.

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

In a circle, the measure of an inscribed angle is equal to half the measure of the intercepted arc.

Therefore, if the inscribed angle measures 114 degrees, then the minor arc it intercepts has a measure of twice that, or:

2 × 114 = 228 degrees

Hence, the measure of the minor arc intercepted by the inscribed angle is 228 degrees.

Answer:

The third side is sqrt(77)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

2^2 + b^2 = 9^2

4+ b^2 = 81

Subtract 4 from each side

b^2 = 81-4

b^2=77

Take the square root of each side

sqrt(b^2) = sqrt(77)

b = sqrt(77)

The third side is sqrt(77)
