The expression of b over negative 5.6 is less than or equal to negative 4.9 for b ≤ 0.7 ( b less than or equal to 0.7 ).

Based on the given conditions,

Negative 5.6 means = -5.6

Negative 4.9 means = -4.9

Negative 5.6 means ≤ Negative 4.9 means

Then,

-5.6  ≤  -4.9

But,

Let the number b is over negative 5.6,

It means,

We can write,

b + (-5.6)      (Equation-1)

This equation-1 is write into,

b + (-5.6) ≤  -4.9

b - 5.6 ≤  -4.9

b ≤ (-4.9) + 5.6

We can sum or difference the products,

b ≤ 0.7

Therefore,

The expression b over negative 5.6 is less than or equal to negative 4.9 for b ≤ 0.7

He will pay $24.055 after discount and sales tax.

A sales tax is a fee that is paid to the government when specified goods and services are sold. Typically, laws permit the vendor to charge the customer the tax at the time of purchase. Use taxes are typically used to describe taxes on goods and services that consumers pay directly to a governing authority.

Given Data

Car cost = $24.211

Discount = 8%

Car cost after discount:

= 24.211 - 8%

= 22.274

Car cost after sales tax:

= 22.274(8%)

= 22.274 (0.08)

= 1.781

Cost of car =  22.274 + 1.781

Answer: [tex]y=-5x+11[/tex]

Step-by-step explanation:

We can model this with a line.

The slope of the line is [tex]\frac{-29-1}{8-2}=-5[/tex], and so the equation is [tex]y=-5x+11[/tex].

The polynomial is

[tex]10x + y[/tex]

Step-by-step explanation:

4(x - 3) + 5x - x²

If x = 2,

= 4(2 - 3) + 5(2) - (2)²

= 4(-1) + 10 - 4

= -4 + 10 - 4

I guess you want to draw the graph.

The graph is a straight line

-6x - 20 = 4y

When x = 0:

-6(0) - 20 = 4y

y = -20/4 = -5

So, one point on the graph

= (0, -5)

When y = -2:

Plugging y = -2 into the equation:

-6x - 20 = 4(-2)

-6x = -8 + 20 = -12

x = -2

So, another point is (-2, -2)

Mark these 2 points on the graph paper

and draw a line passing through them.

The measures of the unknown angles are as follows:

The measures of each angles can be found as follows:

Therefore,

∠AEB = ∠CED (vertically opposite angle)

∠DEA = ∠BEC (vertically opposite angle)

Vertically opposite angles are equal.

Therefore,

4x = 75 - x

4x + x = 75

5x = 75

x = 75 / 5

x = 15

Therefore,

∠DEA = ∠BEC = 4(15) = 60°

∠AEB = ∠CED  = 360 - 120 / 2 = 240 / 2 = 120°

The probability of rolling an even number or a multiple of 3 is 3/4.

Probability determines the odds that a random event would happen. The probability the event takes place is 1 and the probability that the event does not happen is 0.

An even number is a number that is perfectly divisible by 2.

Probability of rolling an even number = number of sides that are even / total number of sides

Sides that are even = 2, 4, 6

Probability of rolling an even number = 3/6 = 1 / 2

Probability of rolling a multiple of 3 = number of sides that are multiples of 3  / total number of sides

Sides that are multiples of 3 = 3, 6

Probability of rolling a multiple of 3 = 2/6 = 1/2

The probability of event B or C = 1/4 + 1/2 = 3/4

The probability that the amount dispensed per box will have to be increased is 0.0062.

Consider the provided information.

Sample of 16 boxes is selected at random.

If the mean for 1 hour is 1 pound and the standard deviation is 0.1

1 Pound = 16 ounces , then 0.1 Pound = 16/10 = 1.6 ounces

Thus: μ = 16 ounces and σ = 1.6 ounces.

Compute the test probability

z= x−μ/σ/[tex]\sqrt{n}[/tex]

z= 15-16/ 1.6/[tex]\sqrt{4}[/tex]

The Equivalent expressions of  4x+1/2+2x-3 is  6x × 1/2 - 3 .

Expressions that perform similarly but differ in appearance are said to be equivalent expressions. When the same value(s) for the variable are entered, two algebraic expressions that are equivalent will have the same value (s). An expression that is equivalent to another expression but does not share its visual characteristics has the same value or worth. According to algebra, the equivalent formulae 2(2x - 3y + 6) and 4x -6y + 12 are the same. When two expressions can be written similarly or when they can be combined into a single, simpler expression, they are said to be equivalent. Furthermore, if values are replaced for the variable in two expressions and they both yield the same result, you can tell if the expressions are similar.

The values ​​of the trigonometric functions of the 0° angle are, cos 0° = 1, sin 0° = 0 ,tan 0° = 0, cot 0° = ∞, sec 0° = 1 , cosec 0° = ∞.

The simplest definition of a trigonometric function is the function of an angle in a triangle, also known as a circular function. It implies that these trigonometric functions can be used to determine the relationship between a triangle's angles and sides. The fundamental trigonometric operations include sine, cosine, tangent, cotangent, secant, and cosecant.

Now given degree is 0 ,

So, we know that sin 0° = 0,

And cos 0° = 1,

⇒tanθ=sinθ/cosθ,

Here θ = 0°

⇒tan 0° = 0/1,

⇒tan 0° = 0,

Now as cot θ is the inverse of tan θ, we get,

⇒cot θ = 1/tan θ,

⇒cot 0°= 1/0,

⇒cot 0° = ∞,

Now we know that cosec θ is the inverse of sin θ, we get,

⇒cosec θ = 1/sin θ,

⇒cosec 0° = 1/0,

⇒cosec 0° = ∞

And we know that sec θ is the inverse of cos θ we get,

⇒sec θ = 1/cos θ,

⇒sec 0° = 1/1,

A certain plant grows 1 1/6 inches each week. it will rake the plant to grow 6 1/6 inches is 5 weeks 2 days.

Time is ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is part of several measurements that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly the things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without the circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.

A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches

1 week = 7 days

Therefore in 1 day plant grows = [tex]\frac{\frac{7}{6} }{7}[/tex]

                                                        = [tex]\frac{1}{6}[/tex] inch

Now we have to calculate the number of days in which the plant grows [tex]6\frac{1}{6}[/tex]  inches ≈ [tex]\frac{37}{6}[/tex] inch

Number of days = [tex]\frac{Total growth}{growth in one day}[/tex]

                          = [tex]\frac{37}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex]

                          = [tex]\frac{37}{6}[/tex]  × 6

                          = 37 days ≈ 5 weeks and 2 days

It will take plant 5 weeks 2 days to grow [tex]6\frac{1}{6}[/tex] inches.

The value of c is -3.

The factorization of the polynomial is [tex](x+3)(x^3-3x+2)[/tex].

Given that:-

Polynomial P(x) = x⁴ + 3x³ + cx² - 7x + 6 is divisible by (x + 3).

We have to determine the value of c and factorize the polynomial.

Using remainder theorem, putting x = -3 in the given polynomial, we get

[tex]P(-3)= (-3)^4+3(-3)^3+c(-3)^2-7(-3)+6=0[/tex]

P(-3) = 81 -81 +9c +21 +6 = 0

9c + 27 = 0

9c = -27

c = -27/9 = -3

Dividing the given polynomial  x⁴ + 3x³ -3x² - 7x + 6  by (x + 3), we get,
