The answer to this arithmetic expression is approximately 9.9998 x 10¹⁸

A combination of numbers, variables, and operators that represents a quantity or mathematical relationship is called an expression.

First, divide sextillion (10²¹) by nonmillion (10⁶) to get 10¹⁵.

Next, multiply 10¹⁵ by 10,000 to get 10¹⁹.

Subtract 200 million (2 x 10⁸) from 10¹⁹ to get 9.9998 x 10¹⁸.

Finally, add 5,000 to get the result of approximately 9.9998 x 10¹⁸ + 5,000 = 9.9998 x 10¹⁸ + 0.0005 x 10¹⁸ = 9.9998 x 10¹⁸.

Therefore, the answer to this arithmetic expression is approximately 9.9998 x 10¹⁸

Answer:

180

Step-by-step explanation:

Answer: 180ft^3

Step-by-step explanation:

The area of the triangle ABC, obtained using the formula for a triangle where two sides and the included angles are known is the option C

C. 81.1 cm²

The formula for the area of a triangle, where the lengths of two sides and the included angle are known, can be presented as follows;

Area, A = (1/2) × a × b × sin(C)

Where a and b are the lengths of the two sides and the included angle C is the measure of the included angle between the two sides, therefore;

The diagram indicates that we get;

Where;

a = 11 cm and b = 18 cm and the measure of the included angle C = 55°, we get;

A = (1/2) × 11 × 18 × sin(55°) ≈ 81.1

Answer:

rate of change: $0.35; initial value: $2.50; Equation: y= 0.35x + 2.50

Step-by-step explanation:

The rate of change is $0.35 because it's the one to change the total cost of the ice cream. If you get 3 toppings, you'll end up with 1.05 more dollars than if you had 0 toppings. And because of that, the initial value would also be $2.50, that's the minimum price you'll have to pay if you do want a sundae.

The equation is just restating all that, you start with the inital value b=$2.50, and the price will go up by 0.35 for every topping you add to the sundae.

Answer:

x = 30

Step-by-step explanation:

Since l and m are parallel, then

3x + 10 = 40 + 60 = 100 ( subtract 10 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

The area of the sector is A = (360/360)π(6)^2 = 36π square units.

To find the area of a sector of a circle, we first need to know the central angle that defines that sector. We can use the formula A = (θ/360)πr^2 to calculate the area of the sector, where A is the area, θ is the central angle in degrees, r is the radius of the circle, and π is a constant value.

In this case, we know that the radius of the circle is 6 units. Let's consider each of the given arc length:

a. If the arc length is 6 units, then the central angle is 360 degrees, which means that the sector is the entire circle. Therefore, the area of the sector is A = (360/360)π(6)^2 = 36π square units.

b. If the arc length is 3 units, then the central angle is 180 degrees. The area of the sector is A = (180/360)π(6)^2 = 18π square units.

c. If the arc length is 1/6 of the circumference (2πr), then the central angle is 60 degrees. The area of the sector is A = (60/360)π(6)^2 = π(6)^2/6 = 6π square units.

d. If the arc length is 9 units, then the central angle is 540 degrees, which means that the sector covers the circle twice. Therefore, the area of the sector is A = (540/360)π(6)^2 = 81π square units.

In summary, we can use the formula A = (θ/360)πr^2 to find the area of a sector of a circle, given the radius and the central angle. Depending on the arc length, we can calculate the central angle and then use this formula to find the area of the corresponding sector.

Using sampling concepts, it is found that the population of interest is given by:

All American teens who are between the ages of 13 and 17.

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.

Given curve is x = 12 - 9t3, y = t3 - 3t.To find the points of horizontal and vertical tangency, first, we need to find the first derivative of x and y w.r.t t respectively. So that we can find the critical points of the curve and the slope of tangent at that point.

The derivative of x with respect to t is:

dx/dt = -27t²

The derivative of y with respect to t is:

dy/dt = 3t² - 3

The tangent will be horizontal at those values of t for which the derivative of y w.r.t t is zero:

dy/dt = 3t² - 3 = 0t = 1 or t = -1At t = 1, x = 12 - 9 = 3 and y = 1 - 3 = -2

At t = -1, x = 12 - 9 = 3 and y = -1 + 3 = 2So, the two points of horizontal tangency are (3, -2) and (3, 2).The tangent will be vertical at those values of t for which the derivative of x w.r.t t is zero:

dx/dt = -27t² = 0t = 0At t = 0, x = 12 and y = 0.

So, the point of vertical tangency is (12, 0). We are given the equation of the curve as x = 12 - 9t3, y = t3 - 3t. We need to find all the points of horizontal and vertical tangency to the curve. To find the points of horizontal tangency, we need to find the first derivative of y w.r.t t, so that we can find the critical points of the curve and the slope of tangent at that point. The tangent will be horizontal at those values of t for which the derivative of y w.r.t t is zero. The derivative of y with respect to t is:

dy/dt = 3t² - 3

Equating it to zero, we get:

3t² - 3 = 0t² - 1 = 0t = ±1

At t = 1, x = 12 - 9 = 3 and y = 1 - 3 = -2At t = -1, x = 12 - 9 = 3 and y = -1 + 3 = 2So, the two points of horizontal tangency are (3, -2) and (3, 2). To find the point of vertical tangency, we need to find the first derivative of x w.r.t t, so that we can find the critical points of the curve and the slope of tangent at that point. The tangent will be vertical at those values of t for which the derivative of x w.r.t t is zero. The derivative of x with respect to t is:

dx/dt = -27t²

Equating it to zero, we get:

-27t² = 0t = 0

At t = 0, x = 12 and y = 0.So, the point of vertical tangency is (12, 0).

Two points of horizontal tangency are (3, -2) and (3, 2), and the point of vertical tangency is (12, 0).

Step-by-step explanation:

B. The set is linearly independent describe the set. Given vectors are,{[ 1], [-2], [0], [ 0]}{[-5] [ 6] [0] [-7]}{[ 0] [ 0] [0] [ 4]}

To determine if the set of vectors shown to the right is a basis for R3 or not. We can check the rank of the matrix which is obtained by placing the given vectors as column vectors of a matrix and then taking the transpose of that matrix.

Then check the rank of that matrix and compare it with the number of given vectors, if rank is same as the number of vectors given then it forms a basis for R3.

To check the linearly independence and span, we can obtain the echelon form of the matrix and compare the pivot and non-pivot columns of that matrix.If the number of pivot columns is equal to the number of vectors, then they are linearly independent otherwise linearly dependent.Let A be the matrix obtained by placing given vectors as its column vectors and taking transpose of it. i.e

\[A = \begin{bmatrix}1 & -5 & 0\\-2 & 6 & 0\\0 & 0 & 0\\0 & -7 & 4\end{bmatrix}\]Let us obtain the echelon form of the matrix A,\[A = \begin{bmatrix}1 & -5 & 0\\-2 & 6 & 0\\0 & 0 & 0\\0 & -7 & 4\end{bmatrix}\mathop{\xrightarrow{{R_2}+2{R_1}}}\begin{bmatrix}1 & -5 & 0\\0 & -4 & 0\\0 & 0 & 0\\0 & -7 & 4\end{bmatrix}\]\[\mathop{\xrightarrow{-\frac{1}{4}R_2}}\begin{bmatrix}1 & -5 & 0\\0 & 1 & 0\\0 & 0 & 0\\0 & -7 & 4\end{bmatrix}\mathop{\xrightarrow{{R_1}+5{R_2}}}\begin{bmatrix}1 & 0 & 0\\0 & 1 & 0\\0 & 0 & 0\\0 & -7 & 4\end{bmatrix}\]

As the rank of matrix A is 2 and we have 3 vectors in the given set, so the given vectors do not form a basis for R3.Also, we can see that the first two columns of echelon form matrix contain pivot elements and the last column does not have a pivot element. Therefore, we can say that the given set of vectors are linearly independent but they do not span R3. The given options are,

A. The set is a basis for R3 (False)

B. The set is linearly independent (True)

C. The set spans R3 (False)

D. None of the above are true (False) Hence, the correct options is (B).
