find the slope of the line passing through the points (7, -1 ) and ( 3, -6)

Answer:

To factor out the GCF from the given expression, we can use the distributive property. This property states that we can distribute a common factor to all of the terms in an expression by multiplying the common factor by each term separately. In this case, the common factor is n, so we can distribute it to each term by multiplying it by -26, 7, and 13:

(-26n * n) + (7n * n) + (13n * n)

This gives us:

-26n^2 + 7n^2 + 13n^2

We can then combine like terms by adding the coefficients of n^2:

(-26 + 7 + 13) * n^2

This gives us the final result:

-6 * n^2

Therefore, we can factor out the GCF of -6n^2 from the given expression.

The amount that Tom’s most recent book earn is 10^7.

The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

Since Tom’s most recent book earned 10*4 times as much money as his first book which was 10³.

The total amount of the recent book will be:

= 10⁴ × 10³

= 10^(4 + 3)

= 10^7

The amount is 10^7.

The required equations can be used to model the situation is x = 1/2y - 3 and y = 10(x-1)

What is equation ?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

Equations can be classified as either conditional equations or identities. Any value of the variables results in an identity being true. Only certain values of the variables in a conditional equation result in truth. When two expressions are joined together by the equals sign ("="), the result is an equation.

If the smaller number is 3 less than half a larger number, this is expressed as:

x = 1/2y - 3 ⇒(1)

If the larger number is 10 times 1 less than the smaller number, this is expressed as;

y = 10(x-1) ⇒ (2)

Substitute equation 2 into 1 as shown;

x = 1/2y - 3

x = 1/2(10x-10)- 3

x = 5x - 5 - 3

-4x = -8

x = 2

Answer:

  1.8 cans of paint are needed

Step-by-step explanation:

A large statue has a volume of 135 m³ and an area of 81 m², while a small statue has a volume of 5 m³. You want to know the number of cans of paint required to paint the small statue, if each can covers 5 m².

The ratio of linear dimensions on the small statue to those on the large statue is the cube root of their volume ratio:

  sf = ∛(5/135) = ∛(1/27) = 1/3

The area of the small statue is the larger statue's area multiplied by the square of the scale factor:

  smaller area = larger area × (sf)²

  smaller area = (81 m²)(1/3)² = 9 m²

Each can of paint covers 5 m², so the number of cans required is ...

  (9 m²)/(5 m²/can) = 1.8 cans

You will need 1.8 cans of paint to paint the small statue.

(a)  The corresponding angles are congruent.

So, m ∠ TLC = 66°

(b)  m ∠KGX = m ∠DNK = 120°

"Information available from the question"

In the question:

A graphic artist created a design for a flower using four congruent hexagons as shown:

B P⊥M K, m ∠ M Y F=m ∠ F H B, m° W M C=m ∠ W P T, m ∠G X R=66°, m ∠ D N K=(3 x+18)°, and m ∠ W B R=(5 x-8)°.

The sum of the angles in WKNDSP is 720°.

Now, According to the question:

Part(a) Since the four hexagons are congruent

So, the corresponding angles are congruent.

Thus, m ∠ T L C=  m ∠ 6 x R

Since, m ∠ 6 x R = 66°

So, m ∠ TLC = 66°

Part(b) In WKNDSP

m  ∠KWP + m ∠ WPS + m ∠ PSD + m ∠ SDN + m ∠ DNK + m ∠ NKW = 720°

Since, 1)  B P⊥M K => m ∠KWP = 90°

2) m ∠WPS =m ∠NKW =m ∠WBR = (5x - 8)°

3) m ∠PSD = m ∠DNK = (3x + 18)°

4) m ∠SDN = m ∠GXR = 66°

So, 90 + (5x + 8) + (3x + 18) + 66 + (3x + 18) + (5x - 8) = 720°

90 + 5x + 8 + 3x + 18 + 66 + 3x + 18 + 5x - 8 = 720

176 + 16x = 720

16x = 720 - 176

16x = 544

x = 34

=> m ∠DNK = (3x + 18)° = (3 × 34 + 18)° = 120°

Trigonometry is the application of certain functions to determine the value of a quantity. The tree stands 10.77 meters tall.

Some trigonometric functions can be used to solve the given problem. Let s represent the distance from the tip of the tree's shadow to where Aria stands, so that;

s = 27.75 - 23.5

= 4.25 m

s = 4.25 m

Also, let the angle formed by the line connecting the tree's tip and the shadow's tip be, so that;

Tan θ = opposite / adjacent

Here given,

Opposite side = 1.65

Adjacent side = 4.25

          = 1.65 / 4.25

          = 0.3882

θ = Tan⁻¹ 0.3882

  = 21.216

θ = 21.216°

We get θ = 21.216°

The tree's height, h, can be calculated as follows:

Tan 21.216° = h/27.75

h = Tan 21.216° x 27.75

  = 0.3882 x 27.75

h = 10.77m

As a result, the tree's height is 10.77m.

Answer:

1/82.

Step-by-step explanation:

In a cross country race with 40 athletes, 10 of them are on the same team. The probability that the top four finishers are all from that same team is given by the expression 10P4/40P4.

The expression 10P4 represents the number of ways that the top four finishers can be chosen from the team of 10 athletes. Since the order in which the athletes finish does not matter, this is equivalent to choosing 4 athletes from a group of 10 without regard for order, which can be done in 10!/(4!6!) = 210 ways.

The expression 40P4 represents the number of ways that the top four finishers can be chosen from the entire group of 40 athletes. Since the order in which the athletes finish does not matter, this is equivalent to choosing 4 athletes from a group of 40 without regard for order, which can be done in 40!/(4!36!) = 34,650 ways.

Therefore, the probability that the top four finishers are all from the same team is given by the expression 10P4/40P4 = 210/34,650 = 1/164. This can be simplified to 1/82 by dividing the numerator and denominator by 2, so the final answer is 1/82.

Answer:

p(x) = (x+7)(x+5)(-x+1)(x-35).

Step-by-step explanation:

To factor p(x), we can use the following steps:

Find the factors of 35 that add up to 4, which is the coefficient of the quadratic term (x^2). In this case, the factors of 35 that add up to 4 are 7 and 5.

Use these factors to rewrite the quadratic term as the product of two binomials. In this case, we can write the quadratic term as (x+7)(x+5).

Substitute this expression into the original polynomial to get p(x) = (x+7)(x+5) + 2x + 35.

To complete the factorization, we need to find two numbers that multiply to 35 and add up to 2. These numbers are -1 and -35.

Use these numbers to rewrite the remaining linear term as the product of two binomials. In this case, we can write the linear term as (-x+1)(x-35).

Substitute this expression into the polynomial to get p(x) = (x+7)(x+5) + (-x+1)(x-35).

Finally, we can factor p(x) as the product of two quadratics: p(x) = (x+7)(x+5)(-x+1)(x-35).

This is the process of finding the rate of change of the value y (dependent variable) of the function changes with respect to that of the variable x (independent variable). The slope itself describes the direction and steepness of the line.

slope = m = rise / run = [tex]\frac{y2 - y1}{x2 - x1}[/tex],

To find the slope , In the case of a straight line y=mx+b, the slope m=Δy/Δx measures the change in y per unit change in x. This can be interpreted as a measure of "sensitivity''; for example, if y=100x+5, a small change in x corresponds to a change one hundred times as large in y, so y is quite sensitive to changes in x.

Nachelle has x dimes and y nickels.

We know that, A nickel is worth 5 cent, A dime is worth 10 cent and have maximum of $0.8 combined.

So, 5% x + 10% y ≤ 0.8

     5x + 10y ≤ 80

She has at least 11 coins.

So, x + y ≥ 11

Hence, We have two inequalities as:

5x + 10y ≤ 80 and x + y ≥ 11

Similarly, x≥ 0 and y≥ 0.

Now, We'll find the points that lie on the given lines and draw the lines ( refer the given figure )

After drawing the graph, we'll check the inequalities where the portion is true.

If take point (0,0),

5x + 10y ≤ 80

5(0) + 10(0) ≤ 80

0 ≤ 80 which is true, hence we will shade the region which is down because the point (0,0 ) lies in downward region.

Similarly,

x + y ≥ 11

0 + 0 ≥ 11

 0 ≥ 11 which is false hence, we will shade the region which is up because the point (0,0 ) lies in downward region.

In result, We get the common region which is the solution.
