We will thus require 62 cubοid bricks tο create the wall, tο the clοsest whοle brick.

A nοrmal brick is a cubοid, a three-dimensiοnal structure with six rectangular faces.

We need tο have at minimum 42/18 = 2.33 rοws mοre bricks because the wall is 42 inches tall, and each brick is 18 inches tall. We require three rοws οf bricks since we can't have a half rοw.

We require 144/7 = 20.57 bricks each rοw because the wall is 144 inches lοng and each brick is 7 inches lοng. There must be 21 bricks each rοw because we cannοt have half bricks.

The first rοw requires 21 whοle bricks. If a brick is sliced in half, the οther half can be used οn the οther end οf the identical rοw.

21 whοle bricks are alsο required fοr the secοnd rοw. Fοr the remainder οf the rοw, we need οnly 20 full bricks since we can utilise the half-brick we cut during the initial rοw just at start οf the secοnd rοw.

The third rοw requires 21 whοle bricks. We have a spare half-brick that we may utilize at the cοnclusiοn οf the third rοw since we utilized οne in the first rοw.

Hence, 62 cοmplete bricks are needed, which equals 21 + 20 + 21.

Answer:

y > -5

Step-by-step explanation:

The domain of function f is (-∞, 10) U (10, ∞) or {x|x ≠ 10}.

The range of function f is (-∞, -3) U (-3, ∞) or {y|y ≠ 3}.

The inverse of this function is f⁻¹ = (10x - 4)/(3 + x).

The domain of function f⁻¹ is (-∞, -3) U (-3, ∞) or {x|x ≠ 3}.

The range of function f⁻¹ is (-∞, 10) U (10, ∞) or {y|y ≠ 10}.

In Mathematics, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of any function, you should swap both the input value (x-value) and output value (y-value) as follows;

f(x) = y = (3x + 4)/(10 - x)

x = (3y + 4)/(10 - y)

10x - yx = 3y + 4

3y + yx = 10x - 4

y(3 + x) = 10x - 4

f⁻¹ = (10x - 4)/(3 + x)

Step-by-step explanation: It would help if you added the picture but its all good.

The exponential function of the line that goes through points (0, 20) and (2, 180) is y = 20 × 3ˣ.

To find the exponential function of a line that goes through two points, we need to use the general form of the exponential function:

y = a × bˣ

where a is the initial value, b is the base, and x is the independent variable (usually time).

We can use the two points given to find the values of a and b.

Let's start with the point (0, 20):

y = a × bˣ

Plug in x = 0 and y = 20

20 = a ×  b⁰

20 = a ×  1

a = 20

Next, let's use the point (2, 180):

y = a × bˣ

Plug in x = 2 and y = 180

180 = 20 × b²

b² = 180/20

b² = 9

b = 3

Now, plug these values into y = a × bˣ

Therefore, the exponential function y = 20 × 3ˣ

C (bottom of column)

We are given that angle theta 1 (θ1) is 45 degrees, angle theta 2 (θ2) is 60 degrees, and the height of the column BC is 95.62 meters. We want to find the height of the house AB, which we'll call "h".

First, we can use trigonometry to find the length of segment CD. Since we know angle θ2 and the length of BC, we can use the tangent function:

tan(θ2) = opposite / adjacent

tan(60°) = d / 95.62

d = 95.62 * tan(60°)

d ≈ 165.30 meters

Now we can use the fact that angles ABD and CBD are complementary to find the length of segment AD:

tan(θ1) = opposite / adjacent

tan(45°) = h / (d + 165.30)

h = (d + 165.30) * tan(45°)

h ≈ 165.30 meters

Therefore, the height of the house is approximately 165.30 meters.

Step-by-step explanation:

The values of a and b are a = 0 and b = -3, and the quadratic equation of the curve is y = (x - 8)² - 3.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

In this case, the vertex is (8, -3).

So we have -

y = a(x - 8)² - 3

To find the value of a, we need one more point on the parabola.

Let's use the fact that the curve is symmetric about the vertex, so there must be another point with the same y-value, but reflected across the vertex.

Since the vertex is at (8, -3), the reflection would be at (8 - 2a, -3).

So we have -

-3 = a(8 - 2a - 8)² - 3

Simplifying -

0 = a(2a)²

0 = 4a³

So either a = 0 or a is undefined (i.e. the parabola is a horizontal line). But we know the curve has a minimum, so it can't be a horizontal line.

Therefore, a must be 0.

Substituting this into our equation, we get -

y = 0(x - 8)² - 3

y = (x - 8)² - 3

Therefore, a = 0 and b = -3, and the equation is y = (x - 8)² - 3.

This modification will reduce the amount he needs to borrow from the lender and thus lower his monthly mortgage payments.

The down payment is the amount of money that the buyer pays upfront towards the purchase price of the property. The more significant the down payment, the less money the buyer has to borrow from the lender, and this can have a significant impact on the monthly mortgage payments.

In the case of Nick, he has saved up 35,000 for a down payment, which is approximately 18% of the purchase price of the house. If he decides to go with the 20% down payment option, he will need to pay 38,400 upfront, which is 20% of 192,000. The remaining 153,600 will be the amount he borrows from the lender.

Now, let's assume that Nick has taken a 30-year fixed-rate mortgage at 6.25% interest. If he decides to pay 20% down payment, his monthly mortgage payments would be approximately 940. However, Nick wants to spend no more than 30% of his income on his mortgage payment, which is 997.50 per month (30% of 3,325). Therefore, the modification that can be made to this loan to make it a viable option is to reduce the loan amount.

If Nick reduces the loan amount to 153,000, his monthly mortgage payment will be approximately 910, which is within his budget. To achieve this, he will need to increase his down payment to 39,000, which is 20.3% of the purchase price. This modification will reduce the amount he needs to borrow from the lender and thus lower his monthly mortgage payments.

In summary, a larger down payment reduces the amount borrowed from the lender and, consequently, lowers the monthly mortgage payments. To make the loan option viable, Nick needs to increase his down payment to reduce the loan amount and meet his budget.

The required expression represents the value in dollars of the coin n years after Hector found is [tex]$c(n) = 190 \times (1.1)^n$[/tex].

Let's call the percentage increase in value each year "r". We know that after one year, the coin was worth $209, which is 209/190 = 1.1 times what it was worth when Hector found it. So we can set up an equation:

[tex]$190 \times (1 + r)^1 = 209$[/tex]

Simplifying this equation,

[tex]$1 + r = \sqrt[1]{\frac{209}{190}}$[/tex]

1 + r = 1.1

r = 0.1

So the percentage increase in value each year is 10%. To find the value of the coin "n" years after Hector found it, we can use the formula:

[tex]$c(n) = 190 \times (1 + r)^n$[/tex]

Substituting the value we found for "r", we get:

[tex]$c(n) = 190 \times (1.1)^n$[/tex]

So the expression for the value of the coin "n" years after Hector found it is:

[tex]$c(n) = 190 \times (1.1)^n$[/tex]

Therefore, the entire expression becomes:

[tex]\sqrt{(\sqrt{x1\⁰)}} (\sqrt{(\sqrt{x\³})} = x^{(5/4)} * x^{(3/8) }= x^{(15/8)}[/tex]

Now, we need to find the value of x that makes this expression equal to 10.

[tex]x^{(15/8) }= 10[/tex]

Taking the eighth power of both sides:
