Pam needs to save $905 per year for seven years to have enough for her first year with the help of her two grandfathers.

Pam needs to save $903 each year to have enough for her first year of college tuition with the help of her two grandfathers.

To calculate this, we first need to add up the total amount of money Pam's two grandfathers are offering to contribute:

Grandfather 1: $6321

Grandfather 2: $6321

Total Contribution: $12642

We then subtract this total contribution from the total cost of tuition for the first year:

Tuition: $6321

Total Contribution: -$12642

Total Amount Needed: $6321

Finally, we divide this total amount needed by the number of years Pam has to save:

Total Amount Needed: $6321

Years: 7

Amount Needed to Save Each Year: $903

As there is a common ratio between each term so this is a geometric sequence.

The idea of geometric progression can be used to determine how much money you will have in your account after a particular number of years if you deposit money in a bank that offers a fixed annual rate of interest.

In a geometric progression or series, each term is equal to the one before it times the common factor, which is a fixed non-zero multiplier. The number of terms in a geometric series might be either finite or infinite.

Since in 6 12 and 24 the common ratio r=2. That is if we multiply the previous term by 2 we will get the next term so the given sequence is geometric sequence.

❗ The way I solved this problem doesn't involve me using point-slope form like the problem tells you to use❗

⭐ Perpendicular lines have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to

⭐What does "opposite reciprocal" mean?

⭐What is slope-intercept form?

We can find the equation of the perpendicular line by:

1. Substituting the slope into the point-slope form equation:

⭐ Perpendicular lines have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to

The slope of the line the perpendicular like is perpendicular to is [tex]\frac{-1}{2}[/tex].

Therefore, the slope of the perpendicular line is [tex]2[/tex]

Substitute the slope into the point-slope form equation.

[tex]y = 2x + b[/tex]

Now, all we have to do is solve for b.

2. Substituting the given coordinate into the point-slope form equation:

We are given the coordinate (6,9).

[tex]y = 2x + b[/tex]

[tex]9 = 2(6) + b[/tex]

[tex]9 = 12 + b[/tex][tex]-3 = b[/tex]

Substitute "b" into the point-slope form equation.

The best estimate of the solution to the system of equations will be (1, 4). Then the correct option is C.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The system of the equations is given below.

2x + 3y = 12            ...1

4x + 2y = 10           ...2

Divide the equation 2 by 2, then we have

2x + y = 5            ...3

Subtract equation 3 from equation 2, then we have

2x + 3y - 2x - y = 12 - 5

2y = 7

y = 3.5

y ≈ 4

Then the value of 'x' is calculated as,

2x + 3.5 = 5

2x = 1.5

x = 0.75

x ≈ 1

The best gauge of the answer for the arrangement of conditions will be (1, 4). Then, at that point, the right choice is C.

The (a) Hole in the expression is x, (b) The vertical assumption is -10 and (c) the horizontal assumption is that the denominator is greater than the numerator.

You should know that a hole occurs if there is a common term between the the numeration and the denominator when factorized, For vertical assumption, the denominator must be equal to zero and horizontal assumption, numerator will be equal to denominator

The given expression is:

[tex]\frac{x^{2}-2x }{x^{3}-9x^{2} -10x }[/tex]

The Hole is

Factorize the numerator= x²-2x

x is common in the expression

x(x-2)

Factorize the denominator= x³-9x²-10x

x(x²-9x-10)

= [x²-10x+x-10]

x[(x²-10x)+(x-10)]

Simplify further to get

x[x(x-10)+1(x-10)]

=x[(x+1)(x-10)]

Combine numerator and denominator to see the hole

[tex]\frac{x(x-2)}{x(x+1)(x-10)}[/tex]

From the expression the hole is x

b. vertical assumption

The denominator =0

x³+9x²-10x=0

As per the tangent formula, the distance does the laser spot on the wall move if the mirror is rotated by 10 is 2.9m

While we looking into the given question we have identified the following values,

Previous distance = 9.5

And the angle = 30 degrees

Rotated angle = 10 degrees

And the distance is considered as x.

Then as per the tangent formula, it can be written like the following,

=> tan 30/9.5 = tan 10/x

When we apply the tangent value, then we get,

=> 0.5773/9.5 = 0.1763/x

When we perform the cross multiplication, then we get,

=> 0.5773x = 9.5 x 0.1763

=> 0.5773x = 1.6749

Then the value of x is obtained as,

=> x = 1.6749/0.5773

The number of CDs that can be bought are { 5, 4, 3, 2, 1 }.

What is an inequality ?

A relationship between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. So inequality emerges from an imbalance.

Given, No. of CDs = x

A CD costs $11 and He has total $60.

So, According to the question,

No. of CDs × Cost of each CD ≤ 60

                                         x × 11 ≤ 60

                                         11x ≤ 60

                                          x ≤ 60/11

Since the number of CDs can't be in fraction and The maximum CDs can be bought is 5.

So, The possible No. of CDs that can be purchased are { 5, 4, 3, 2, 1 }

The division of the whole numbers is not closed under property as the division of whole number is not always a whole number.

A set has the closure property under a particular operation if the result of the operation is always an element in the set.  If a set has the closure property under a particular operation then we say that the set is “closed under the operation.” The closure property of the division tells that the result of the division of two whole numbers is not always a whole number. Whole numbers are not closed under division that is  a ÷ b is not always a whole number.

For example, 5 and 8 are whole numbers, but 5÷8 is not a whole number.

To compare two numbers, a, and b, we can write two inequalities:

a < b when a is less than b

a > b when a is greater than b.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We may write two inequalities to compare two numbers, a and b:

a < b

a > b

If a is less than b, then the first inequality is true and the second is false. If a is greater than b, then the first inequality is false and the second is true. Otherwise, if a and b are equal, then both inequalities are false.

We can determine which inequality is true by comparing the values of a and b and using the rules of inequality.

For example, if a=3 and b=5, then we can determine that a < b is true and a > b is false because 3 is less than 5.

On the other hand, if a=8 and b=2, then we can determine that a < b is false and a > b is true because 8 is greater than 2.

When two lines are crossed by a transversal, a number of angle pairs are formed. The sum of the measures of these angle pairs can be used to solve for unknown angles in the diagram.

Here are some of the angle pair relationships that hold for two lines crossed by a transversal:

Using these relationships, you can set up equations to solve for unknown angles in the diagram. For example, if you are trying to find the measure of angle A, you might use the fact that corresponding angles are congruent to set up the equation "m<A = m<D". Then, you can use other angle pairs to find the measures of the other angles, and solve the system of equations to find the measure of angle A.
