Q is the centroid of the triangle. What is the length of QK?

The two rectangles are joined to get the shape. And the area of the shape is 258 square feet.

The amount region shows how much an area is on a planar or hemispherical cup. Surface region alludes to the region of an open surface or the boundary of a multi-object, while the region of a plane locale or plane field alludes to the region of a structure or planar material.

The shape is a mix of the two rectangular shapes. Then the region is likewise the amount of these two square shapes. Then we have

A = (18 - 8) x (21 - 12) + 21 x 8

A = 10 x 9 + 21 x 8

A = 90 + 168

A = 258 square feet

Melanie's account balance after t years is, A = 500 x [tex](1 + 0.00425)^{4t[/tex].

Compound interest is when you receive interest on both your interest income and your savings.

Given:

Initial deposit = $ 500

Interest rate = 1.7 % = 0.017/4 = annual compounded quarterly

Now, Account balance = Initial deposit x [tex](1 + r)^{4t[/tex]

                                   A = 500 x [tex](1 + 0.00425)^{4t[/tex]

Where:

A = Account balance

4t = Number of quarters (4 x Number of t years)

Suppose we want to calculate the account balance after 4.5 years, then we substitute this way:

A = 500 x [tex](1 + 0.00425)^{4(4.5)[/tex]

The limit of (3x - 3)^(5/2) as x approaches 4, [tex]\lim_{x \to } _4[/tex] (3x - 3)^(5/2) is 243.

The limit of a function as x approaches a certain value can be thought of as the value that the function approaches as x gets arbitrarily close to that value.

To find the limit of (3x - 3)^(5/2) as x approaches 4, we need to evaluate the expression for values of x that are close to 4 and see what the result approaches.

First, let's substitute 4 for x in the expression:

[tex]\lim_{x \to } _4[/tex] (3x - 3)^(5/2) = (3*4 - 3)^(5/2)

                                = (9)^(5/2)

Answer: Length = 90 meters

Width = 20 meters

Step-by-step explanation: Step 1: The formula for the area of a rectangle is A = length x width, so we can solve for the length of the field:

A = 2000

length x width = 2000

length = 2000 / width

Step 2: The formula for the perimeter of a rectangle is P = 2(length + width), so we can solve for the width of the field:

P = 180

2(length + width) = 180

2length + 2width = 180

2width = 180 - 2length

width = (180 - 2length) / 2

Step 3: Substitute the equation for width into the equation for length to solve for length:

A = 2000

length x (180 - 2length) / 2 = 2000

2length2 - 180length + 2000 = 0

length2 - 90length + 1000 = 0

(length - 90)(length - 10) = 0

length = 90

Step 4: Substitute the value of length into the equation for width to solve for width:

width = (180 - 2length) / 2

width = (180 - 2(90))

Answer: The expression (6-√)(15-√) can be simplified by using the distributive property of multiplication over addition:

(6-√)(15-√) = 6 * 15 + 6 * (-√) + (-√) * 15 + (-√) * (-√)

Expanding the first two terms:

6 * 15 = 90

6 * (-√) = -6√

Next, we'll use the identity for the product of two square roots:

(-√) * 15 + (-√) * (-√) = 15√ - √^2

Since the square root of a positive number is positive, √^2 = √. So:

15√ - √^2 = 15√ - √

Putting everything together:

(6-√)(15-√) = 90 - 6√ + 15√ - √

Combining like terms:

(6-√)(15-√) = 90 + 9√

So, the expression (6-√)(15-√) without a perfect square factor in the radicand is:

(6-√)(15-√) = 90 + 9√

Therefore, the answer is:

Answer:

The answer to this question depends on the values of the numbers involved. In general, when you multiply a number by a fraction, the product will be smaller than the largest factor if the fraction is less than 1. For example, if you multiply 5 by 1/2, the product is 2.5, which is smaller than 5. On the other hand, if you multiply a number by a fraction that is greater than 1, the product will be larger than the largest factor. For example, if you multiply 5 by 2/1, the product is 10, which is larger than 5.

In conclusion, the size of the product obtained from multiplying a number by a fraction depends on the values of the numbers involved and can be either smaller or larger than the largest factor.
