Answer:

$182.90

Step-by-step explanation:

Find the cost per kg. To do so, divide the total cost, with the amount of kg that is bought:

(Total Cost/Total weight) = (cost/unit):

[tex]\frac{106.20}{18} = 5.9\\\\[/tex]

$5.9 per kg of apple.

~

Next, solve for the amount that 31 kg of apples would cost. Multiply the unit cost with the amount of kg of apples purchased:

(Total weight of apples x Cost per kg for apples) = Total cost:

[tex]31 * $5.9 = Total Cost\\Total Cost = 182.9[/tex]

$182.90 is your answer.

The length of TS  in ΔTRS using Similarity of triange is 12 cm .

If two items have the same shape or have the same shape as their mirror images, they are said to be Similar. One can be produced from the other more accurately by evenly scaling it, perhaps with the addition of further translation, rotation, and reflection.

If the sides are in the same ratio or proportion and the angles are equal (corresponding angles), two triangles will be comparable (corresponding sides). Similar triangles may have varying individual side lengths, but they must have equal angles and the same scale factor or matching ratio of the side lengths. If two triangles resemble one another, then

In ΔTPQ and ΔTPS

∠T is common in both triangle

PQ ║ RS

∴∠TPQ = ∠TRS (Corresponding Angles)

similarly ,

∠TQP = ∠TSR

∴ Δ TPQ ~ ΔTRS

So,

The value of S, i.e., prependicular length in right angled triangle is twelve units.

We have, a right angled triangle ABC as see in above figure. From the above figure, we get the following information,

The base length of right angled ∆ ABC, BC = 9 units

The perpendicular length/height of

∆ ABC , AC = S units

The hypotenuse length of ∆ ABC, AB

= 25 units

We have to calculate the value of S i.e., the prependicular length. Using the Pythagoras threoem to solve the value of S,

(hypotenuse)²= (base)² + (prependicular)²

=> AB² = BC² + AC²

=> 15² = 9² + S²

=> 225 = 81 + S²

=> 225 - 81 = S²

=> S² = 144

=> S = ±√144

=> S = ± 12

The logarithmic function f(x) = log_b x is a decreasing function if and only if b > 1.

To see why, consider that for any positive real number x, log_b x increases as x increases. This can be seen by using the definition of logarithms: log_b x is the power to which b must be raised to produce x. As x increases, the power to which b must be raised to produce x must also increase, so log_b x must increase as well.

Therefore, if b > 1, then log_b x is a strictly decreasing function, because as x increases, the power to which b must be raised to produce x increases at an increasing rate, so log_b x decreases at an increasing rate. On the other hand, if 0 < b < 1, then log_b x is a strictly increasing function, because as x increases, the power to which b must be raised to produce x increases at a decreasing rate, so log_b x increases at a decreasing rate.

It is important to note that for b = 1, the logarithmic function is undefined, as log_1 x is not defined for any positive real number x.

Step-by-step explanation:

You want to show that (3x+4) is a factor of f(x) = 6x^2+5x-4, and you want the other factor.

When the product, f(x), is divided by one of its factors, the remainder will be zero and the quotient will be the other factor.

The equation for the altitude AR of triangle ABC will be 4y-3x=0 i.e. B.

What is a triangle?

Triangles are polygons in geometry that have three sides and three vertices. This figure is two-dimensional and has three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.

A triangle is categorized into three categories based on its sides, namely:

Scalene Triangle - Each side has a distinct length.

Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.

Equilateral Triangle - A triangle has three sides that are of the same length.

A triangle is categorized into three categories based on its angles, namely:

Acute Angle Triangle - A triangle with all of its angles smaller than 90°.

Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.

Triangle with a Right Angle - A triangle with one of its angles equal to 90°.

Now,

The general form of the linear line is:

y = mx + c where m is the slope and c is the y-intercept

Step 1: getting the slope:

Since AR is the altitude of ABC, therefore, AR is perpendicular on BC which means that slope of AR = -1/slope of BC

Therefore, we will need to get slope of BC:

We have point B = (0,4) and point C = (3,0)

slope of BC = (y2-y1) / (x2-x1) = (0-4) / (3-0) = -4/3

This means that:

slope of AR = m = 3/4

Step 2: getting the y-intercept:

Since point A belongs to the altitude, therefore, point A satisfies the equation of the line. So, to get the y-intercept, we will use point A to substitute in the equation of the line and solve for c as follows:

y = mx + c

y = (3/4) x + c

0 = (3/4)(0) + c

c = 0

Hence,

           y = (3/4) x

Total thirty-nine months will be take by Johnson family to pay off the balance, $10,000.00.

The monthly payment is the amount paid per month to pay off the principle in the time period of the loan. If your rate is r%, divide r/100 by 12 to calculate your monthly interest rate. Formula for monthly payment is, M = Pr(1+r)ⁿ/{(1+r)ⁿ - 1 }

where, P --> principle

r--> rate of interest in months

n --> number of periods (in months )

In this problem, Johnson family bought the furniture and appliances for a new house that is principle, P = $10,000

Rate of interest, R = 15%

In terms of months, R = 0.15/12

= 0.0125 per month

Monthly payment, M = $325.00

Plugging all known values in above formula we get, $325.00 = {$10,000 × 0.0125(1 + 0.0125)ⁿ}/{(1+ 0.0124)ⁿ - 1 }

=> 325 = 125(1.0125)ⁿ/{(1.0125)ⁿ - 1}

=> 325 {(1.0125)ⁿ - 1} = 125(1.0125)ⁿ

=> 325(1.0125)ⁿ - 325 = 125(1.0125)ⁿ

=> 325(1.0125)ⁿ - 125(1.0125)ⁿ = 325

=> 200 (1.0125)ⁿ = 325

=> (1.0125)ⁿ = 325/200 = 13/8 = 1.6250

Taking natural logarithm both sides

=> ln(1.0125)ⁿ = ln (1.6250)

=> n ln(1.0125) = ln (1.6250) = 0.4855

=> n×0.0124 = 0.4855

=> n = 0.4855/0.0124 = 39.153 ~ 39

Limits are the rate of change of a function and also used in many other concepts such as continuity, differentiability and many other concepts in calculus.

In calculus, limits are used to study the behavior of a function as the input, or independent variable, approaches a specific value. The limit of a function at a particular point, say x = a, is defined as the value that the function approaches as the independent variable x gets arbitrarily close to a, but not necessarily equal to it.

The notation for a limit is usually represented as:

lim x->a f(x) = L

Which means as x approaches a, f(x) approaches L.

Properties of limits include:

1) The limit of a constant is equal to the constant.

2) The limit of a sum, difference, or product of functions is equal to the sum, difference, or product of their limits, respectively.

3) The limit of a function at a point is unique, if it exists.

Answer:

PART A : points to graph (7,0)(1,-1)(2,-5)

(x, y) become (-x, y)

Here,

(-4, 2) become (4, 2)

(2, 1) become (-2, 1)

(1,-3) become (-1,-3)

Similarly a point P(x, y) translated by vector <3, -2> means the point P become P'(x+3, y-2)

Longitude is the measure of a location's east-west position on the Earth's surface. It is measured in degrees east or west of the Prime Meridian, which is an imaginary line that runs from the North Pole to the South Pole through the Royal Observatory in Greenwich, England. Longitude values range from -180 degrees (West) to 180 degrees (East).

Latitude, on the other hand, is the measure of a location's north-south position on the Earth's surface. It is measured in degrees north or south of the Equator, which is an imaginary line that runs around the Earth's middle, dividing it into the Northern and Southern Hemispheres. Latitude values range from -90 degrees (South) to 90 degrees (North).

The percent error is a measure of how accurate a measurement is. It is calculated by taking the difference between the measured value and the true value, dividing that difference by the true value, and then multiplying by 100 to get a percentage.

In this case, the true value of the baseball's speed is 4.2 miles per hour and the measured value is 5 miles per hour. To find the percent error:

(5 - 4.2) / 4.2 * 100 = 0.190476 * 100 = 19.0476%

So the percent error in this measurement is 19.0476%. This means that the measurement was off by 19.0476% from the true value.

Alternatively, we can round it to 19% for ease of interpretation

Therefore, the percent error in this measurement is 19%.
