Find the value of x please please help

Answer:

\(8 {x}^{2} - 6x - 5 = x\)

\(8 {x}^{2} - 7x - 5 = 0\)

x = (7 + √((-7)^2 - 4(8)(-5)))/(2×8)

= (7 + √(49 + 160))/16

= (7 + √209)/16

= -.4661, 1.3411 (to 4 decimal places)

The garden club is planting fruit trees in their school's garden, and they have two types of trees: one large tree that needs a lot of fertilizer and several newly planted trees that need a much smaller amount of fertilizer. The large tree requires 5 pounds of fertilizer.

which is a significant amount compared to the smaller trees, which only need 0.5 pounds of fertilizer each.

The reason for the difference in fertilizer requirements is due to the size and age of the trees. The large tree is likely fully grown and mature, and therefore requires a substantial amount of fertilizer to support its growth and fruit production. The younger and smaller newly planted trees, on the other hand, need much less fertilizer since they are still growing and developing.

Providing the proper amount of fertilizer is crucial to ensuring healthy tree growth and fruit production, which is why the garden club is treating the larger tree differently than the smaller ones. By giving each tree the proper amount of fertilizer necessary for their growth stage, the garden club is helping ensure the success of their fruit tree planting project and ultimately helping to contribute to the schools' educational and environmental goals.

Answer:

A^n = [4^n 4^n

0 1]

Step-by-step explanation:

To find the solution for the 2x2 matrix A:

[4 4

0 1] to the nth power = [ ]

We can use matrix multiplication to raise A to the nth power. Let's start with n = 1:

A^1 = [4 4

0 1]

Now, let's solve for A^2 by multiplying A^1 by A:

A^2 = A x A^1

= [4 4 [4 4

0 1] 0 1]

= [16 16

0 1]

Next, let's solve for A^3:

A^3 = A x A^2

= [4 4 [16 16

0 1] 0 1]

= [64 64

0 1]

We can see a pattern emerging:

   A^1 = [4 4

   0 1]

   A^2 = [16 16

   0 1]

   A^3 = [64 64

   0 1]

We can generalize this pattern as follows:

A^n = [4^n 4^n

0 1]

Therefore, the solution for the 2x2 matrix A raised to the nth power is:

A^n = [4^n 4^n

0 1]

The remainder theorem indicates that remainder when the polynomial x⁵ - 3·x⁴ - 2·x³ - 5·x² + 5·x + 12 is divided by (x - 1) is 8

The remainder theorem specifies the relationship between the division of a polynomial by a linear factor to the value of the polynomial at a specified point

The remainder when the polynomial expression; x⁵ - 3·x⁴ - 2·x³ - 5·x² + 5·x + 12 is divided by x - 1, can be found using the remainder theorem by plugging in x = 1 in the function as follows;

f(1) = 1⁵ - 3 × 1⁴ - 2 × 1³ - 5 × 1² + 5 × 1 + 12 = 8

The remainder when x⁵ - 3·x⁴ - 2·x³ - 5·x² + 5·x + 12 is divided by (x - 1) therefore is 8

Answer:

The maximum amount that Kathy can contribute to a SEP IRA for 2018 is based on her net self-employment income. To calculate this amount, she first needs to subtract her self-employment expenses from her revenues to get her net self-employment income:

$132,000 - $52,800 = $79,200

Next, she can calculate the maximum amount she can contribute to a SEP IRA using the following formula:

Net self-employment income * 0.20 = Maximum SEP contribution

So for Kathy, the calculation would be:

$79,200 * 0.20 = $15,840

Therefore, the maximum amount Kathy can contribute to a SEP IRA for 2018 is $15,840

Kathy can contribute the full amount of $15,840 to a SEP IRA for 2018.

A break-even point is a moment at which an incident's total cost and total income are equal. An organization has recouped its expenditures but has not yet achieved a profit at the break-even point.

To calculate the amount, we first need to determine Kathy's net self-employment income by subtracting her self-employment expenses from her self-employment revenues:

Net self-employment income = Revenues - Expenses

= $132,000 - $52,800

= $79,200

The maximum amount that Kathy can contribute to a SEP IRA is 20% of her net self-employment income, up to a limit of $55,000 for 2018. So to find the maximum amount that Kathy can contribute, we multiply her net self-employment income by 20%:

Maximum contribution = 20% × Net self-employment income

= 20% × $79,200

= $15,840

Since $15,840 is less than the maximum limit of $55,000 for 2018, Kathy can contribute the full amount of $15,840 to a SEP IRA for 2018.

Answer:

m= -1

Step-by-step explanation:

Given:

m/m plus 4 plus 4/4-m = m^2/m^2-16

interpreted as

m / ((m+4)(4-m)) = m^2/(m^2-16)

Solution

m / ((m+4)(4-m)) = m^2/(m^2-16)

rearrage and expand

-m / ((m+4)(m-4)) = m^2 / ((m+4)(m-4))

if m does not equal 0, we can cancel terms in numerator

-1 / ((m+4)(m-4)) = m / ((m+4)(m-4))

if m does not equal +4 nor -4, we can cancel terms in denomnator

-1 = m

Hence m=-1 if m does not equal 0, -4 or +4, which is valid.

The rule for such reflections is:

Apply the rule to the given point to get:

By using the general formula for a reflection across the x-axis, we will see that the new coordinates of the center are (-3, -4)

For any point (x, y), if we perform a reflection across the x-axis, the only thing we are doing is changing the sign of the y-component.

So the reflection is:

(x, y) → (x, -y)

Using the fact that ∠A is congruent to ∠B and ∠C is a complement of ∠A, we determined that the measure of ∠B is 65° based on the given measure of ∠C as 25°.

If ∠A is congruent (≅) to ∠B and ∠C is a complement of ∠A, we can use the properties of complementary angles to find the measure of ∠B.

Given that m∠C = 25° and ∠C is a complement of ∠A, we know that ∠A + ∠C = 90°.

Since ∠A is congruent to ∠B, we can replace ∠A with ∠B in the equation:

∠B + ∠C = 90°.

Substituting the given value, we have:

∠B + 25° = 90°.

To isolate ∠B, we subtract 25° from both sides of the equation:

∠B = 90° - 25°.

Simplifying, we get:

∠B = 65°.

Therefore, the measure of ∠B is 65°.

Answer: Half of them are even and half of them are odd.

Step-by-step explanation:

The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.

The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.

Therefore, out of the given numbers, half of them are even and half of them are odd.
