Solve the equation for p, then justify your reasoning. -9p - 17 = 10

Answer:

We can write 7 + 2 + 1 in two different ways.

a)

b)

Step-by-step explanation:

The commutative property of addition states that we can add the numbers in any order and get the same answer.

For example, if we add 'a' and 'b' together, the commutative property of addition states that we would get the same answer whether we add a + b or b+a.

In other words,

a + b = b + 1

In our case, we are given

7 + 2 + 1

According to the commutative property of addition, we can add the number in any order and get the same answer.

Therefore, we can write 7 + 2 + 1 in two different ways.

a)

b)

Verification:

Thus, the answer will remain the same in any order.

i.e.

7 + 2 + 1 = 7 + 1 + 2 = 1 + 7 + 2

Answer: C

Step-by-step explanation:

Another point on the line y = 9/5(x) + 2  is (0, 2).

The correct option is B.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:

The slope of the line is 9/5 and passes through the point (-10, -16).

So, the equation of the line is,

y + 16 = 9/5(x + 10)

y + 16 = 9x/5 + 18

y = 9/5(x) + 2

From the given choices,

Substituting x = 0,

we get,

y = 2

another point on the line is (0, 2).

Therefore, another point on the line is (0, 2).

16,0

0,6

Step-by-step explanation:

Answer:

Substitute 0 for the x-value in the equation and solve for y. The result is y = 6, so the y-intercept is at (0, 6). Next, substitute 0 for the y-value in the equation and solve for x. The result is x = 16, so the x-intercept is at (16, 0).

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

[tex]a_n=7\cdot \:2^{n-1}[/tex]

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

[tex]a_n=a_1\cdot r^{n-1}[/tex]

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

[tex]\frac{14}{7}=2,\:\quad \frac{28}{14}=2[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=2[/tex]

now substituting r = 2 and a₁ = 7 in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=7\cdot \:2^{n-1}[/tex]

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

[tex]a_n=7\cdot \:2^{n-1}[/tex]

Answer: C

Step-by-step explanation:

Since the heights of the men are assumed to be normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = heights of the men.

µ = mean height

σ = standard deviation

From the information given,

µ = 70.7 inches

σ = 2.1 inches

The probability that they have a mean height greater than 71.7 inches is expressed as

P(x > 71.7) = 1 - P(x ≤ 71.7)

For x = 71.7

Since n = 36, then

z = (71.7 - 70.7)/2.1/√36 = 2.86

Looking at the normal distribution table, the probability corresponding to the z score is 0.998

P(x > 71.7) = 1 - 0.998 = 0.002

Answer:

x = 2, y= -1 Or (2, -1)

Step-by-step explanation:

Let’s solve the system using substitution. First we can set the equations equal to each other:

x-3= -2x +3

Now solve for x

3x-3= 3

3x = 6

x=2

Now that we have x, we can plug it back into one of the original equations to get y

y= x-3

y= 2-3

y = -1

Finally, the solution to the system of equations is (2, -1).

Answer:

(2,-1)

Step-by-step explanation:

1.) y = x - 3

    y = -2x + 3

2.) Multiply top equation by 2

    2y = 2x - 6

    y = -2x + 3

3.) Add equations

    3y = -3

4.) Divide 3 from each side

     y = -1

5.) Substitute -1 for y in second equation

    -1 = -2x + 3

6.) Solve

     -4 = -2x

     x = 2

Therefore, (2, -1)

43.3in²

Step-by-step explanation:

The area of the equilateral triangle in the simplest radical form is 43.3 (inches)².

A simple polygon having 3 sides and three interior angles make up triangles. One of the fundamental geometric forms, it is represented by the symbol and comprises three connected vertices. Triangles can be categorized into the number of different varieties according to their sides and angles.

According to the information provided in the question,

Side of the equilateral triangle, a = 10 inches.

Area, a = (√3)/4 × a²

a = (√3)/4 × 10²

a = 43.3 (inches)²

Therefore, the area is 43.3 (inches)².

Answer:

1539

Step-by-step explanation:

We solve the above question using the Exponential decay formula

= A(t) = Ao(1 - r) ^t

Ao = Initial Amount invested = 7600

r = Decay rate = 55% = 0.54

t = time in weeks = 2

Hence:

A(t) = 7600(1 - 0.55)²

A(t) = 7600 × (0.45)²

A(t) = 1539

Therefore, the value of the quantity after 2 weeks is 1539

What is differentiation?

In mathematics, differentiation is the process of determining the derivative, or rate of change, of a function. Differentiation is a technique for determining a function's derivative. Differentiation is a mathematical procedure that determines the instantaneous rate of change of a function based on one of its variables. The process of finding the derivative of dependent variable in an implicit function by differentiating each term separately

Given data ,

Let the profit P for producing n DVD copies be P ( n )

where P ( n ) = −0.02n² + 3.40n − 16

Now , to find the maximum number of DVDs to produce in order to maximize the profit is calculated by finding the derivative of P ( n ) with respect to n

And , dP (n) / dn = 0

So , the equation will be

P ( n ) = −0.02n² + 3.40n − 16

dP (n) / dn = -0.04n + 3.4

When dP (n) / dn = 0 , we can find the value for n

So ,

-0.04n + 3.4 = 0

Adding 0.04n on both sides , we get

0.04n = 3.4

Divide by 0.04 on both sides , we get

n = 85

Hence , The number of DVDs the company can sell to maximize the profit is 85
