Maria's abuela gave her $2000.00 for her quinceañera under the condition that she had to deposit it in a savings account for 42 months. How much interest will she have if the account earns 7.8% per annum simple interest?

Answer:

(a)

smaller value = 125 ft

larger value = 250 ft

(b)

31250 ft²

Step-by-step explanation:

(a)

In total, the farmer used 875ft worth of fencing.

In terms of x, the total fencing used is: 2x + x + x + x + 2x = 7x

This means 7x=875ft. Dividing both sides by 7, we find x=125ft

The dimensions of the rectangular enclosure in terms of x are "x and 2x". Subbing in 125ft for x, these dimensions become "125ft and 2(125ft)" or "125ft and 250ft".

(b)

Since we know the enclosure is 125ft long and 250ft wide, and since the area of a rectangle is its length times its width, the are of the enclosure is:

125ft * 250ft = 31250 ft²

Answer:

(a)

smaller value =125 ft

larger value = 250 ft

(b)

31250 ft?

The length of the side is 12 units in simplest radical form with a rational denominator.

A triangle is said to be equilateral if all of its sides and angles are equal. An equilateral triangle is also known as an equiangular triangle since each of its angles has a value of 60 degrees.

Given:

The triangle given in the image is an equilateral triangle.

That means the angle measure of the triangle is 60° each.

And all the sides are equal.

To find the value of x:

Sin(60/2)° = opposite/ hypotenuse.

Sin30° = x/6

x = 6/Sin30°

[tex]x = \frac{6}{1/2}[/tex]

x = 6(2)

x = 12

The set of numbers for which the statement that the square root of a number is greater than the square of the number is true, is equals to (0,1). So, right choice is option (a).

In mathematics, when we multiplying the number by itself, the result is called square of number. This is usually equivalent to raising a number to the power of 2. For example, square of 4 is 4² = 16. The square root of a number is that factor of a number which when multiplied by itself the original number. Square root of number is usually equivalent to raising a number to the power of 1/2. It is represented using the symbol '√'. Now, we have to check the options and determine where square root of a number is greater than the square of the number.

a) (0, 1), if we plug f(x) = √x , x∈(0,1) and g(x) = x² , x∈(0,1) on calculator then we get, the value of f(x) is greater than g(x), i.e, x = 1/2 , f(1/2) = 0.70 and g(1/2) = 0.25.

b) [0, 1], if we plug x = 0 then f(0) = 0 , g(0) = 0

that is f(x) is greater than and equal to g(x). But we have to consider only greater than not equal.

c) [1,∞), closed bracket again represents equality which is not consider. So, statement is false for it.

d) (1,∞), here number inbetween 1 and infinite but not for all reals it is true that square root of a number is greater than the square of the number, for example x = 2 , f(2) =1.414, g( 2) = 4 implies f(x)< g(x) for x = 2. So, the statement is false for it.

Hence, required option is option (a).

The statistical measurement known as the Z-score describes the connection between a value and the mean of a set of values and the required z-score to the three decimal places is −2.714.

The relationship between a value and a set of values' mean is described by the statistical measurement known as the Z-score.

Standard deviations from the mean are used to measure Z-score.

A Z-score of zero means the data point's score is the same as the mean score.

Your observed value is 2.5 standard deviations from the mean if your Z-score is 2.5, and so on.

Your value is more closely aligned with the mean the closer your Z-score is to zero.

Your value is further from the mean the farther your Z-score is from zero.

So, let's say Rosetta wins the game on Thursday with 110 points.

When x=110, the z-score is -2.714.

The average is 148.

You can see from this z-score that x=110 is 2.714 standard deviations away from the mean.

This formula can be used to determine the z-score:

z = x−μ/σ

=110−148/14

=−38/14

≈−2.714

Therefore, the required z-score to the three decimal places is −2.714.

The statements are (a) False, (b) True and (c) False

Right angles are angles whose measure is 90 degrees.

In the figure, AE, BF, DG, and HC intersect at point H, and FHG is a right angle.

(a) ∠AHB and ∠AHG are vertical angles.

Vertical angles are angles which are formed on the opposite sides of two intersecting lines.

∠AHB and ∠AHG are not formed on the opposite sides, but are adjacent to each other.

So the statement is false.

(b) ∠EHF and ∠DHE are adjacent angles.

∠EHF and ∠DHE are two angles which are adjacent to each other. So they are adjacent angles.

So the statement is true.

(c) The measure of ∠FHG is equal to the measure ∠DHF.

We know that DG is a straight line.

∠FHG and ∠DHF are linear pair of angles.

So, ∠FHG + ∠DHF = 180°

Given that ∠FHG is right angle.

90° + ∠DHF = 180°

∠DHF = 180° - 90°

∠DHF = 90°

So the statement is true.

Step-by-step explanation:

d = vt + 16t² , that is

vt + 16t² = d

substitute d = 480, v = 16 into the equation

16t + 16t² = 480 ( divide through by 16 )

t + t² = 30 ( subtract 30 from both sides )

t² + t - 30 = 0 ← in standard form

(t + 6)(t - 5) = 0 ← in factored form

Answer:

Step-by-step explanation:

To determine the percentage increase between 2017 and 2018, we need to calculate the difference between the two years and then divide by the 2017 value and multiply by 100. So, the calculation would be:

(9960,000 - 9640,000) / 9640,000 * 100 = 3.125%

So, the number of households increased by 3.125% from 2017 to 2018.

To find the number of households in 2019, we need to find the increase from 2018 to 2019. We can do this by multiplying the number of households in 2018 by the percentage increase, and then add that to the 2018 value. So, the calculation would be:

9960,000 * (3.125 / 100) + 9960,000 = 10,298,800

Therefore, there would be approximately 10,298,800 households in 2019, rounded to the nearest ten thousand.

Answer: I do not have the capability to create a graph. However, I can tell you how to graph the parabola h(x) = -x^2 + 3.

A parabola is defined by its equation in the form y = ax^2 + bx + c, where a, b, and c are constants. In this case, a = -1, b = 0, and c = 3.

The vertex of the parabola is the highest or lowest point on the graph and is given by the coordinates (-b/2a, c - b^2/4a). For this parabola, the vertex is (0, 3), since b = 0 and a = -1.

To find another point on the parabola, you can plug in any x-value and use the equation of the parabola to find the corresponding y-value. For example, if you plug in x = -2, you get:

h(-2) = -(-2)^2 + 3

h(-2) = 4 + 3

h(-2) = 7

So the point (-2, 7) is also on the parabola.

With the vertex and one other point on the parabola, you can now graph the parabola.

the displacement is 23.14m and the velocity is 21.28m/s

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form. A non-zero term (a 0) for the coefficient of x2 is a prerequisite for an equation to be a quadratic equation. The x2 term is written first, then the x term, and finally the constant term is written when constructing a quadratic equation in standard form. In most cases, the numerical values of letters a, b, and c are expressed as integral values rather than fractions or decimals.

The given equation y  = 25t - 1.86t²

at t =  1

So the displacement y = 25-1.86 = 23.14

to find velocity dy/dt = 25- 2(1.86)t

v = 25 - 3.72 = 21.28m/s

Hence the displacement is 23.14m and velocity is 21.28m/s

The total time (in hours) Mary trained both workouts on Wednesday = 10

Where x represents the length (in hours) of each of the Plan A workout, and B represents the time in hours of each of the Plan B workout, we get;

Similarly, the number of Plan A workouts trained on Thursday = 2

Number of Plan B workout trained on Thursday = 6

The duration of training of all workouts on Thursday = 10 hours
