Monica deposits ​$100 into a savings account that pays a simple interest rate of 3.7​%. Paul deposits ​$200 into a savings account that pays a simple interest rate of 2.4​%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she​ correct? Justify your response.

Answers

No, Monica is incorrect. Paul will get more interest in 1 year

What is simple interest?

Simple interest is the interest amount for a particular principal amount of money at some rate of interest

Formula: Simple interest :

Principal x rate x time/100

Given: For Monica, Principal =$100, rate = 3.7%

Interest in 1 year = 100 x 3.7 x 1/100

=$3.7

For Paul, Principal =$200, rate = 2.4%

Interest in 1 year =200 x 2.4 x 1/100

= $4.8

Thus , Paul will get more interest in 1 year.

Therefore, Monica is incorrect.

What do you mean by residual value * Mcq?

Answers

The estimated value of an asset that is fixed at the end of its useful life or lease term is its residual value, which is often referred to as salvage value.

What is Mcq, or salvage value?

When an item reaches the end of its useful life, its salvage value—or potential market value—is estimated. It can also be described as the asset's book value after depreciation has been taken into account.

What does the depreciation formula's residual value mean?

The asset's final worth is its residual value. To obtain the entire amount, it is therefore deducted from the starting value. Consequently, we are given the depreciation figure. This sum is divided by the usable years of the asset using the straight-line depreciation technique.

What is meant by Bhaskara's equation?

The sine approximation formula of Bhaskara I is a rational equation in one variable for computing the approximations of the trigonometric sines found by Bhaskara I (c. 600–c. 680), an Indian mathematician of the seventh century.

Indian astronomer and mathematician Bhaskara II lived in the 12th century. He created a number of the same foundations and findings that are entirely attributable to Europeans and are still very helpful in modern science and forecasts, such as a basic form of calculus.

Here we have the equation:

y = 4 × x² - 4 × x - 1

And the graph should be available (you can see it below this answer)

Now, we're seeking answers to:

4 × x²- 4 × x - 1 = 0

The two x values at which the graph of our function intersects the y = 0 line, or the x-axis, will be these solutions.

The next step is to identify the two x values where our graph crosses the x-axis.

We can estimate the solutions in the graph as follows:

x = -0.2

x = 1.2

The Bhaskara's equation can be used to determine the precise solutions, and we will discover that the solutions are provided by:

[tex]$x=\frac{-(-4)+-\sqrt{(-4)^2-4 * 4 *(-1)}}{2 * 4}=\frac{4+-\sqrt{32}}{8}=\frac{4+-5.66}{8}[/tex]

What is Heron's formula for area of triangle Class 9?

Answers

Heron's formula is a formula used to calculate the area of a triangle when the lengths of its three sides are known.

It is named after Hero of Alexandria, a Greek mathematician and engineer who first derived this formula.

The formula states that the area of a triangle is equal to the square root of the product of the semi-perimeter (half the sum of the three sides) and the differences of the semi-perimeter and each side.

Mathematically, Heron's formula can be written as:

A = √(s(s-a)(s-b)(s-c)),

where A is the area of the triangle, s is the semi-perimeter and a, b, c are the length of the three sides of the triangle.

For example, if the lengths of the three sides of a triangle are 5 cm, 6 cm and 7 cm, then the semi-perimeter (s) is (5 + 6 + 7)/2 = 9 cm.

Using Heron's formula, the area of the triangle is:

A = √(9(9-5)(9-6)(9-7)) = √(9*4*3*2) = √432 = 6.48 cm2

Are triangles ABC and ADC congruent?

Answers

No, triangles ABC and ADC are not congruent.

To determine if two triangles are congruent, we must use the Side-Angle-Side (SAS) Congruence Theorem. This theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of a second triangle, then these two triangles are congruent.

In this case, we can see that sides AB and AD are equal, but angles A and D are not equal. Therefore, triangles ABC and ADC are not congruent. To prove this calculationally, we can use the Law of Cosines. First, we can calculate the length of side BC by using the Law of Cosines:

BC^2 = AB^2 + AC^2 - 2AB * AC * cos(A)

BC = √(AB^2 + AC^2 - 2AB * AC * cos(A))

Then, we can calculate the length of side DC by using the Law of Cosines:

DC^2 = AD^2 + AC^2 - 2AD * AC * cos(D)

DC = √(AD^2 + AC^2 - 2AD * AC * cos(D))

Finally, we can compare BC and DC. Since BC ≠ DC, we can conclude that triangles ABC and ADC are not congruent.

Answers

The correct set of numbers that can represent the sides of an acute triangle among the options given is 5, 7, 8.

To determine if a set of numbers can represent the sides of an acute triangle, we can use the rule that the sum of the squares of the two smallest sides should be greater than the square of the largest side. By applying this rule

it can be seen that set B (5, 7, 8) satisfies this condition and is therefore an acute triangle,

while the other sets do not satisfy this condition and therefore are not acute triangles. It's worth noting that there can be multiple sets of numbers that can represent the sides of an acute triangle.

Find the measures of x and y. Explain your process

Answers

Using the fact that the sum of the interior angles of a triangle must be 180°, we will see that y = 70°, and x and y are vertical angles, so x = 70°.

How to find the measures of x and y?

First, remember that the sum of the interior angles of a triangle is always equal to 180°, then we can write a linear equation to find the value of y.

y° + 60° + 50° = 180°

We can solve that for y, we will get:

y° = 180° - 60° - 50°

y° = 180° - 110°

y° = 70°

Then the measure of angle y is 70 degrees.

Now, notice that angles x and y are vertical angles (have a common vertex but no common sides).

Vertical angles always have the same measure, then the measure of angle x is also 70°.

Answers

The length available will be (300-W) feet, where W represents the breadth (width) of the rectangle.

Let L, A, and W represent the length, area, and width of the rectangular field respectively.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

Based on the data given we have,

2L + 2W = 60

=>2L=60-2W

=>L=(60-2W)/2

=>L=2(30-W)/2

∴ L=(30-W) feet

Thus, the length available will be (300-W) feet.

What happens when a figure is dilated by a scale factor of less than 1?

Answers

When a figure is dilated by a scale factor of less than 1, it becomes smaller as the coordinates of each point on the figure will be multiplied by a value less than 1. This results in a reduction of the size of the figure while preserving its shape.

For example, if a figure is dilated by a scale factor of 0.5, the coordinates of each point on the figure will be multiplied by 0.5. This means that each point on the figure will be moved half as far from the origin as it was before the dilation.

The result of this is that the dilated figure will be smaller than the original figure and will have a scale factor of less than 1.

It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.

The expression (5-x) underneath the other root is simultaneously set to be greater than 0. We do not allow (5-x) to equal 0.

As a result, 5-x > 0 becomes 5 > x or x 5 when x is removed. This is the result of adding x to both sides.

In addition to the two inequalities, we also have x < 5. In order to describe a number between -2 and 5, we must include -2 but not 5.

solve for c 2(c+1)=10

Answers

The algebraic equation have the value of c equal to 4.

What is algebraic equation

An algebraic equation is a mathematical statement that involves two equated algebraic expressions.

The unknown value c can be evaluated for the agebraic equation 2(c + 1) = 10 as follows:

open brackets

2c + 2 = 10

subtract 2 from both sides of the equation

2c + 2 - 2 = 10 - 2

2c = 8

divide through by the coefficient of c

2c/2 = 8/2

x = 4

Therefore, the value of c that makes the algebraic equation true is 4.

We have proved that given polygons are similar polygons.

What are similar polygons?

Similar polygons are polygons that have the same shape, but possibly different sizes. Two polygons are similar if and only if their corresponding angles are congruent (equal in measure) and the ratio of the lengths of their corresponding sides is always the same, regardless of which pair of corresponding sides is chosen.

The similar polygons will have the same angles. in the given figure they all have the right-angle.

also if we take the ratio of their corresponding lengths, we get

12/8 = 24/16

3/2 = 3/2

So we can say that both polygons are similar.

Hence, we have proved that given polygons are similar polygons.
