Use the equation below to find v, if u = 18, a = 6, and t = 4

v = u + at

Based on the equation y = 3x+40 where y is the number of stamps and x is number of weeks after Paul inherited the stamps, the correct statement is since inheriting the collection, Paul has bought 3 new stamps each week.

According to the question,

We have the following information:

y = 3x+40 where y is the number of stamps and x is number of weeks after Paul inherited the stamps

Now, when we observe this equation carefully, we notice that 3x is added to 40. So, it means that 40 is constant. Then, the number of stamps increasing per week is in the multiplication of 3. Or, in other words, 3 new stamps are bought each week.

For 1st week:

y = 3*1+40

y = 43

For 2nd week:

y = 3*2+40

y = 6+40

y =46

Hence, the correct option is C.

The statements about lines that is true are

A. Line 11y = 55 is vertical.

C. For both lines, all points on the line have an x and a y-coordinate.

D. For either line, one of the coordinates of all of the points is always the same value.

Lines given to us are

1. 7x = -21

x = -3

2. 11y = 55

y = 5

Now let us check the statements.

A. Line 11y = 55 is vertical.

Yes, it is absolutely true as y = 5 will be a straight vertical line from origin of the graph (0 , 0) to (0 , 5)

B. Line 7x= -21 is vertical.

No, this statement is not true as this will be a horizontal line from (0 , 0) to (-3 , 0)

C. For both lines, all points on the line have an x- and a y-coordinate.

Yes, for both the lines there will be both x and y coordinate as every point on graph has x and y coordinates to represent them.

D. For either line, one of the coordinates of all of the points is always the same value.

Yes, this statement is true as for first line x coordinate is a constant value of 0 and for second line y is a constant value of 0.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The two triangles are similar.

Now,

Since, The two triangles are similar.

So, We get the sides are proportional to each other.

Hence, We can formulate;

⇒ 4/5.6 = 7/x

Solve for x as;

⇒ x = 7 × 5.6 / 4

⇒ x = 9.8 m

And, 4/5.6 = 8/y

Solve for y;

⇒ y = 8 × 5.6 / 4

⇒ y = 11.2 m

Thus, The value of x will be 9.8 m.

All the real numbers x in the expression such that (3x - 27)³ + (27x - 3)³ = (3x + 27x - 30) is x = 1 .

In the question ,

it is given that the expression is

(3x - 27)³ + (27x - 3)³ = (3x + 27x - 30)

By using the identity a³ + b³ [tex]=[/tex] (a + b)(a² - ab + b² )

we get ,

[(3x - 27 + 27x - 3)] × [(3x - 27)² - (3x - 27)(27x - 3) + (27x - 3)² ] = 30x - 30

(30x - 30)×[(3(x - 9))² - (3(x - 9) × 3(9x - 1)) + (3(9x - 1))²] = 30x -30

using the identity (a-b)² [tex]=[/tex] a² -ab + b²

(30x - 30) × [9( x² - 18x + 81) - (9(9x² - 82x + 9)) + (9(81x² - 18x + 1)) = 30x-30

9(30x - 30)×[x² - 18x + 81 - 9x² + 82x - 9 + 81x² - 18x + 1] = 30x - 30

270×(x - 1)×[ 73x² + 46x + 73] = 30(x - 1)

taking (x-1) terms to LHS ,
we get

(270 - 30)×(x - 1)[ 73x² + 46x + 73 ] = 0

(240) (x - 1) [ 73x² + 46x + 73 ]  =  0     ....because 270-30 = 240

Dividing both sides by 240

we get ,

(x - 1) [73x² + 46x + 73] = 0

So , either x - 1 = 0    or      73x² + 46x + 73 = 0

on solving 73x² + 46x + 73 = 0

we get the discriminant of 73x² + 46x + 73  a negative number , so it cannot have real root .

hence x -1 = 0

x = 1

Therefore , the only real solution is x = 1 .

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given are the sides of triangle as AB = 18cm, BC = 18cm, AC = 16cm.

The given triangle is a isosceles triangle with two sides equivalent. Angles opposite to these sides will be equal. So, we can write -

2∠x + ∠y = 180°

from the figure, it can be seen that angle B is 5.38 degrees.

2∠x + 5.38 = 180

2∠x = 174.62

∠x = 87.31°

You want the result of a division operation performed on numbers written in scientific notation.

In each case, the result number will have a repeating decimal fraction. We show 4 significant figures in the answer. The number of significant figures you need to use will depend on what you're using the answer for. If you are required to match the precision of the numbers here, you will want to use 1 significant figure.

The rules of exponents apply, so the exponent of the result will be the difference of the exponents of numerator and denominator. As always, if the numerator mantissa is smaller than the denominator mantissa, the result will be a fraction, so adjustment of the exponent will be necessary.

Additional comment

Any scientific or graphing calculator and any spreadsheet can accept input in scientific notation and format the output in the same way.

You need to be careful with the way you enter the multiplier. Most calculating platforms accept the E notation shown in the attachment. If you use multiplication (×10^-9, for example), then the denominator number will need to be enclosed in parentheses. The third line of the second attachment shows the result of not using parentheses: the multiplier intended for the denominator instead multiplies the result of the division. (This behavior is required by the Order of Operations.)

The price of the lumber per square foot is $115.

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Given that the cost of the lumber yard plywood per square meter is $1240.

The cost of the lumber plywood per square foot is calculated as,

Cost = $1240 per square meter

The square meter is equal to 1 m = 3.28 ft. The cost will be calculated as,

Cost = $1240 / m²

Cost = $1240 / (3.28)² ft²

Cost = $115 per square feet

The function operation (f + g)(x) of the functions f(x) = √( 16x⁴ ) and g(x) = 3x² - 3x - 5 is -5x² + 5x - 7.

A function is simply a relationship that maps one input to one output.

Given the functions in the question;

To determine the function operation (f + g)(x), replace the function designators with the functions and simplify.

(f + g)(x) = f(x) + g(x)

(f + g)(x) = √( 16x⁴ ) + ( 3x² - 3x - 5 )

Replace √( 16x⁴ ) with 4x²

(f + g)(x) = 4x² +  3x² - 3x - 5

Collect and add like terms

(f + g)(x) = 7x² - 3x - 5

Therefore, the function operation (f + g)(x) is 7x² - 3x - 5.

What is transformation of points?

The reflection is the type of alteration that takes place when each point in the shape is reflected over a line. The picture is on the opposite side of the line from the pre-image when the points are reflected across a line, but it is still at the same distance from the line as the pre-image. The reflection of each point (p, q) onto an image point (q, p).

12) Reflect (2, 3) over the x axis:

Since, the x-coordinate of a point that is reflected across the x-axis stays constant, but the y-coordinate is assumed to be the additive inverse.

The x-axis' reflection of point (x, y) is (x, -y).

So, (2, 3) becomes, (2, -3).

13) Reflect (7, -2) over the y axis:

Since, the y-coordinate of a point that is reflected across the y-axis stays constant, but the x-coordinate is assumed to be the additive inverse.

So, (7, -2) becomes, (-7, -2).

14) Rotate (4, 5) 90° about the origin:

(x, y) → (-y, x) is the formula for a 90° rotation about the origin.

So, (4, 5) becomes, (-5, 4).

15) Rotate (-3, -2) 270° about the origin:

(x, y) → (y, -x) is the formula for a 270° rotation of the origin.

So, (-3, -2) becomes, (-2, 3).

16) Reflect (17, -23) over the line y=x.

The angle at which the point (x, y) is reflected across the line y = x is (y, x).

So, (17, -23) becomes, (-23, 17).

An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls). The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two things.

Given ratio,
