Using the general recursive formula, he 25-th term in the arithmetic sequence is 29.7

Here we have an arithmetic sequence with the first term a₁ = 3.3 and the common difference is d = 1.1

Remember that the general arithmetic recursive formula is:

aₙ = a₁ + (n - 1)*d

This formula allows us to find the n-th term of the arithmetic sequence only using the first term and the common difference.

In this case, we just need to replace n by 25 and the values written above.

a₂₅ = 3.3 + (25 - 1)*1.1 = 29.7

We can conclude that the 25th term in the sequence is 29.7

The slope of the line 3x - 2y = -12  is 3/2 .

The equation of a straight line can be written as follows,

y = mx + c                                         equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is 3x - 2y = -12 .

To get the slope of this given equation we need to convert the given equation in the format of equation of a straight line i.e., equation1. So now we will rearrange the given equation as,

  3x - 2y = -12

⇒ 2y = 3x + 12

Now on dividing this equation by 2 on both sides, we will get

⇒ y = (3/2)x + 6                                               equation 2

On equating equation 1  and equation 2, we will get

Slope of the line = m = 3/2.

Intercept = c = 6

The slope of the line 3x - 2y = -12  is 3/2 .

The solution of the given linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is at x = 1.5.

According to the given question.

We have a linear equation in one variable.

0.2(x+3)-4(2 x-3)=0.9

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofore, the solution of the linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is given by

0.2(x+3)-4(2 x-3)=0.9

⇒ 0.2x + 0.6 -8x + 12 = 0.9

⇒ -7.8x + 12.6 = 0.9

⇒ -7.8x  = 0.9 - 12.6

⇒ -7.8x = -11.7

⇒ x = -11.7/(-7.8)

⇒ x = 1.5

Hence, the solution of the given linear equation in one variable 0.2(x+3)-4(2 x-3)=0.9 is at x = 1.5.

The cylinder's total surface area includes the area of the curving surface as well as the areas of the two circle-shaped bases of the cylinder.

The area of the two bases and the area of the curved surface are added to determine the cylinder's total surface area. Consequently, the following is the formula for the cylinder's total surface area:

Area of the two bases plus the area of the curved surface equals the cylinder's total surface area. Due to the cylinder's round bottoms, their combined area will be equal to r2 + r2. We already know that a cylinder's curved surface area is 2rh.

(r2 + r2 + 2rh) is the cylinder's total surface area.

⇒ 2πr2 + 2πrh

Total surface area of cylinder = 2πr(r+h)

Step-by-step explanation:

see picture for reference.

The maximum allowable weight for a disc with circumference 66.92 centimeters Round to the nearest tenth is 176.9 grams.

A circle's outside boundary is called the circumference and can be measured, or calculated, by using

Circumference = 2πr

where r is the radius of circle.

Now it is given that,

the maximum weight, w of a disc in grams is 8.3 times the diameter, d in centimeters

⇒ w ≤ 8.3d

and  the maximum allowable weight for a disc with circumference 66.92 centimeters

So, Circumference = πd   [∵ d = 2r]

∴ 66.82 = πd

⇒ d = 66.82π

Thus,  w ≤ 8.3*66.82π grams

⇒ w ≤ 176.89 grams

Round to the nearest tenth, w ≤ 176.9 grams

Thus, the maximum allowable weight for a disc with circumference 66.92 centimeters Round to the nearest tenth is 176.9 grams.

The solution of the system of equations involving 3x + 7y = 15 and 5x + 2y = -4 is  (-2 , 3).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

3x + 7y = 15     (equation 1)

5x + 2y = -4     (equation 2)

Using the first equation, find the value of one variable, lets say x, in terms of the other.

3x + 7y = 15     (equation 1)

3x = 15 - 7y

x = 5 - (7/3)y

Substitute the equation of x to the second equation.

5x + 2y = -4     (equation 2)

5[5 - (7/3)y] + 2y = -4

25 - (35/3)y + 2y = -4

Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.

25 - (35/3)y + 2y = -4

- (35/3)y + 2y = -4 - 25

-(29/3)y = -29

y = 3

Substitute the value of y in the equation of x.

x = 5 - (7/3)(3)

x = 5 - 7

x = -2

Hence, the solution of the given system of equations is (-2 , 3).

Step-by-step explanation:

what is B in your question ? you did not tell us.

since you mention "fraction", I assume B is the slope of a line ?

if that is the case, please remember, the slope is (y coordinate change / x coordinate change) when going from one point of the line to another.

the way you phrased it I assume the slope was originally negative.

that means either the y difference or the x difference was negative (but not both, otherwise it would have been a positive fraction again).

let's look at what happens, when things get reflected across the y axis :

things go from the left side (negative x values) to the right side (positive x values) of the y axis or vice versa.

and things stay on the same side of the x axis (either above the x-axis with positive y values, or below the x-axis with negative y values).

so, that reflection causes the x values to flip their sign, but the y values stay the same.

so, if y was originally negative, then x must have been positive. after the reflection x is now negative too, that makes the y/x fraction -/- = +/+ positive.

if y was originally positive, then x must have been negative. after the reflection x is now positive too, that makes the y/x fraction +/+ positive.

therefore, in every case, the reflected slope fraction must be positive.

The expression representing the amount remaining will be 45 - 2.50x.

Table of values

At x = 1 Amount = 42.50

At x = 2 Amount = 40.

From the information, Malika uses the card to buy one cup of coffee. Each cup of coffee costs $2.50 and the original amount of money on the gift card was $45.

Therefore, the expression representing the amount remaining will be:

A = 45 - (2.50 × x)

A = 45 - 2.50x

At x = 1 Amount remaining will be:

= 45 - 2.50

= 42.50

At x = 2

A = 45 - 2.50x

A = 45 - 2.50(2)

The transformation of function f(x) to function g(x) is given by g(x)=A f(Bx+ H)+K. where the constant A scales the function vertically. (A negative A reflects the function about the x-axis B scales the function horizontally. (A negative B reflects the function on the y-axis.) H shifts the function horizontally, and K shifts the function vertically.

Convert f(x) to g(x)

where the conversion is g(x)=f(x)+2.

A perpendicular line has negative reciprocal slopes, so for g(x) to be perpendicular to f(x), we need to get the negative reciprocal of -x, which is -1(1/-x)
