Answer:

  47.5 cm

Step-by-step explanation:

You want the height of a trapezoid with bases of lengths 135 cm and 105 cm, and an area of 5700 cm².

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

Filling in the given values, we have ...

  5700 = 1/2(135 +105)h

  5700 = 120h

  h = 5700/120 = 47.5

The height of the tabletop is 47.5 cm.

A sequence of transformation that would move ΔABC onto ΔDEF is: D. a dilation by a scale factor of 1/2, centered at the origin, followed by a 90° clockwise rotation about the origin.

In Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

In this scenario an exercise, we would dilate the coordinates of the pre-image by applying a scale factor of 1/2 that is centered at the origin as follows:

Ordered pair B (-4, 2) → Ordered pair B' (-4 × 1/2, 2 × 1/2) = Ordered pair B' (-2, 1).

In Mathematics and Geometry, a rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction;

(x, y)                               →            (y, -x)

Ordered pair B' (-2, 1)   →          E (1, 2)

The  correct relation symbol

1. LN < RN

2.  LR > LN

3. RN > LN

4. m∠L < m∠N

5. m∠N = m∠R

To determine the correct relation symbols in the given situations, we need to compare the given values in the triangle ∆LRN.

A. In ∆LRN, m∠L = 61° and m∠R = 48°.

LN < RN: The measure of ∠L is greater than the measure of ∠R. By the angle-side relationship, this indicates that the side opposite ∠L (LN) is shorter than the side opposite ∠R (RN). Therefore, LN < RN.

LR > LN: The sum of the measures of ∠L and ∠R is greater than 180° (61° + 48° = 109°), indicating that ∆LRN is an obtuse triangle. In an obtuse triangle, the longest side is the one opposite the obtuse angle, which is LR. Therefore, LR > LN.

RN > LN: In a triangle, the length of any side is greater than the length of the side opposite the smaller angle. Since ∠L is greater than ∠R, the side opposite ∠L (LN) is shorter than the side opposite ∠R (RN). Therefore, RN > LN.

B. In ∆LRN, LN = 8cm, RN = 12cm, and LR = 15cm.

m∠L < m∠N: In a triangle, the measure of any angle is larger than the measure of the angle opposite the shorter side. Since LN is the shortest side, the angle opposite LN (∠L) will have a smaller measure than the angle opposite the longer side, which is ∠N. Therefore, m∠L < m∠N.

m∠N = m∠R: In an isosceles triangle, the angles opposite the equal sides are congruent. Since LR = LN, it indicates that ∆LRN is an isosceles triangle, and therefore, m∠N = m∠R.

Answer:

11x² - 23x - 15

Step-by-step explanation:

(3x + 2)(x - 9) + 2x(4x + 1)

(3x + 2)(x - 9)

3x² - 27x + 2x - 18

3x² - 25x - 15

2x(4x + 1)

8x² + 2x

3x² - 25x - 15 + 8x² + 2x

11x² - 23x - 15

So, the answer is 11x² - 23x - 15

Answer:

the simplified expression is 13x^2 - 23x - 18.

Step-by-step explanation:

To simplify the expression (3x + 2)(x - 9) + 2x(4x + 1), we can apply the distributive property and then combine like terms. Let's break it down step by step:

Step 1: Expand the expression using the distributive property.

(3x + 2)(x - 9) + 2x(4x + 1)

= (3x)(x) + (3x)(-9) + (2)(x) + (2)(-9) + (2x)(4x) + (2x)(1)

Step 2: Simplify each term.

= 3x^2 - 27x + 2x - 18 + 8x^2 + 2x

Step 3: Combine like terms.

= 3x^2 + 8x^2 + 2x^2 - 27x + 2x + 2x - 18

= 13x^2 - 23x - 18

As we have proved that the matrix u can be written as a linear combination of the column vectors of a, which implies that u lies in the plane in ℝ3 spanned by the columns of a.

Let us consider the given vectors u=−16 13 20 and the matrix a=5 −7 −2 4 2 2. To determine whether u lies in the plane in ℝ3 spanned by the columns of a, we need to check whether u can be written as a linear combination of the column vectors of a.

We can express the matrix a as a linear combination of its column vectors as follows:

a = 5 4 −2 ⋅ [1 0 0] + (-7) 2 4 ⋅ [0 1 0] + (-2) 2 2 ⋅ [0 0 1]

Therefore, the column vectors of a span a plane in ℝ3.

Now, let us try to express u as a linear combination of the column vectors of a:

u = α[5 4 −2] + β[-7 2 4] + γ[-2 2 2]

where α, β, and γ are constants to be determined.

Setting up a system of linear equations, we get:

5α − 7β − 2γ = −16

4α + 2β + 2γ = 13

−2α + 4β + 2γ = 20

Solving this system of equations, we get α = −4, β = −1, and γ = 3.

Yes, Debt on early stage of our life may lead to not qualify for the mortgage and auto loan. The statement is True.

An obligation to pay money or another agreed-upon value to a third party, the creditor, is known as a debt. Debt differs from an immediate purchase in that payments are deferred or made in installments. Debt can be defined as the sum that the borrower owes the lender. A debt is an amount of money that has been borrowed for a set period of time and must be repaid, plus interest. The borrower's creditworthiness affects both the debt's size and its acceptance.

A credit score is a numerical expression used to quantify a person's creditworthiness. It is based on a level examination of their credit files. The main component of a credit score is a credit report, which is normally obtained from credit agencies.

The differential equation that models the rate of change of the sum S(t) with respect to time t is given by dS/dt = k * e^(0.05t).  The formula for the sum S(t) is S(t) = (k/0.05) * e^(0.05t) + C. It is not possible to determine the exact value of k that will result in $3,500,000 in 41 years.

(a) The differential equation that models the rate of change of the sum S(t) with respect to time t is given by dS/dt = k * e^(0.05t), where k represents the annual investment amount and e^(0.05t) represents the continuous compounding growth factor.

(b) To determine a formula for the sum S(t), we need to integrate the rate of change equation from part (a). Integrating both sides with respect to t, we have ∫dS = ∫k * e^(0.05t) dt. Integrating the left side gives S(t), and integrating the right side gives (k/0.05) * e^(0.05t) + C, where C is the constant of integration. Thus, the formula for the sum S(t) is S(t) = (k/0.05) * e^(0.05t) + C.

(c) In order to find the value of k that will provide $3,500,000 in 41 years, we can use the formula derived in part (b) and substitute the given values. The equation becomes 3500000 = (k/0.05) * e^(0.05*41) + C. To determine the value of k, we need to know the constant of integration C or have additional information about the initial conditions. Without this information, it is not possible to determine the exact value of k that will result in $3,500,000 in 41 years. However, with the given equation, you can solve for the value of k by rearranging the equation and solving numerically using methods such as iteration or numerical approximation techniques.

The area of the field is 10,765.44 square meters.

Given that:

Diameter, d = 72 m

Width, W = 72 m

Length, L = 93 m

The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.

The area of the field is calculated as,

A = (π/4)d² + W·L

A = (3.14 / 4) x 72² + 72 x 93

A = 4,069.44 + 6,696

The interest cost and the total amount due on a six month loan is  $1500 and total amount due is $1599

SI is equal to 100. r = 10% T=6 months, or 6/12 years.

Idea employed: SI = Prt/100. Interest rate in principle.

Calculation: P = (100 100 12)/(10 6) 100

= (P 10 6)/(12 100)

P = 2000.

For instance, if your current APR is 17.99% and you currently owe $500 on your credit card over the course of the month, you can get your monthly interest rate by dividing 17.99% by 12, which is roughly 1.49%. Then multiply $500 by 0.0149 to get a monthly payment of $7.45.

annual interest = $1,599

 full amount due = ($1,500 + $99).

= $1599

The given bounded region is the set

\(R = \left\{(x,y) ~:~ 0 \le x \le 1 \text{ and } x^4 \le y \le x^{1/4} \right\}\)

assuming the curves are \(y=x^4\) and \(x=y^4\implies y=x^{1/4}\) (since \(x>0\) in the first quadrant).

The coordinates of the centroid are \((\bar x, \bar y)\) where \(\bar x\) and \(\bar y\) are the average values of \(x\) and \(y\), respectively, over the region \(R\). These are given by the ratios

\(\bar x = \dfrac{\displaystyle \iint_R x \, dA}{\displaystyle \iint_R dA} \text{ and } \bar y = \dfrac{\displaystyle \iint_R y\,dA}{\displaystyle \iint_R dA}\)

Compute the area of \(R\).

\(\displaystyle \iint_R dA = \int_0^1 \int_{x^4}^{x^{1/4}} dy \, dx \\\\ ~~~~~~~~ = \int_0^1 \left(x^{1/4} - x^4\right) \, dx \\\\ ~~~~~~~~ = \frac45 - \frac15 = \frac35\)

Integrate \(x\) and \(y\) over \(R\).

\(\displaystyle \iint_R x \, dA = \int_0^1 \int_{x^4}^{x^{1/4}} x \, dy \, dx \\\\ ~~~~~~~~ = \int_0^1 x \left(x^{1/4} - x^4\right) \, dx \\\\ ~~~~~~~~ = \int_0^1 \left(x^{5/4} - x^5\right) \, dx \\\\ ~~~~~~~~ = \frac49 - \frac16 = \frac5{18}\)

\(\displaystyle \iint_R y \, dA = \int_0^1 \int_{x^4}^{x^{1/4}} y \, dy \, dx \\\\ ~~~~~~~~ = \frac12 \int_0^1 \left((x^{1/4})^2 - (x^4)^2\right) \, dx \\\\ ~~~~~~~~ = \frac12 \int_0^1 \left(x^{1/2} - x^8\right) \, dx \\\\ ~~~~~~~~ = \frac12 \left(\frac23 - \frac19\right) = \frac5{18}\)

Then the centroid's coordinates are

\(\bar x = \dfrac{\frac5{18}}{\frac35} = \boxed{\frac{25}{54}} \approx 0.463\)

\(\bar y = \dfrac{\frac5{18}}{\frac35} = \boxed{\frac{25}{54}}\)

A spurious correlation is the implied causal relationships between events that are statistically  linked.

Spurious correlation;

A spurious correlation (or spuriousness) in statistics is an apparent causal relationship between two variables. Any reported dependencies between variables are solely the result of chance or are both a result of an unidentified confounder when there is misleading correlation.

When the price of higher education and the cost of living both rise, for instance, this doesn't necessarily indicate a causal link between the two factors because higher education tuition isn't always the result of rising living costs.
