We knoe that 2 to the third is 8. when you square to a negative power, you do squaring normally, and then take the reciprocal of that number. so 8 to the second power is 64, and we flip it over, sp the answer is 1/64

The diagonals of the parallelogram intersect at the center. Then the value of the variable 'x' is 38.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal. Its diagonals intersect in the center.

Given parallelogram A B C D below, DE = 31 If EB = x - 7.

By the definition, then the equation is given as,

EB = DE

x - 7 = 31

Simplify the equation, then we have

x - 7 = 31

x = 31 + 7

x = 38

The value of the variable 'x' is 38.

Answer:

Step-by-step explanation:

The measurement  that  is accurate to 25 grams is 0.025Kg.

Measurement can be described as the  quantification of attributes  involving an object or event,  and it can be used in making comparism with other objects or events.

Hence  measurement serves as as way of  determining how large or small a physical quantity with respect to  basic reference quantity of the same kind.

1kg = 1000g

then X Kg = 25gram

Then cross multiply,  X = (25/ 1000)= 0.025kg

Answer:

56

Step-by-step explanation:

56 would be the arc. reasoning is because line CG form an arch of 56 and Angle A and C also form a angle of 34

The exact value of cos A in simplest radical form is \(\sqrt{3}\)/2.

find the exact value of cos A in simplest radical form. Here's how you can solve this problem:

We know that cos A is adjacent over hypotenuse. We also know that we have a 30-60-90 triangle with a hypotenuse of 8. \(\angle\)A is the 60-degree angle.

Let's label the side opposite the 60-degree angle as x. Since this is a 30-60-90 triangle, we know that the side opposite the 30-degree angle is half of the hypotenuse.

Therefore, the side opposite the 30-degree angle is 4.Let's apply the Pythagorean theorem to find the value of the other side (adjacent to 60-degree angle):

x² + 4² = 8²x² + 16 = 64x² = 48x = \(\sqrt{48}\)x = 4\(\sqrt{3}\)

Now that we know the value of the adjacent side to the 60-degree angle,

we can use it to find cos A:cos A = adjacent/hypotenuse = (4\(\sqrt{3}\))/8 = \(\sqrt{3}\)/2

To determine the price of the keyboard with the coupon, we need to know how much Tiana spent. Let's call the original price of the keyboard "x".

According to the coupon, Tiana will receive a discount of $150 for every $500 spent. So, if she spends x dollars, she will receive a discount of (x/500) * $150.

The price of the keyboard with the coupon will then be x - (x/500) * $150.

Since the original price is not specified, we cannot determine the exact price of the keyboard with the coupon.

The probability sampling method in which you randomly select one of the first k elements and then select every k element thereafter is known as c. systematic sampling. Therefore, option c. systematic sampling is correct.

Systematic sampling is a probability sampling technique where the sample is chosen by selecting every kth element from the population, where k is a constant. This method is often used when the population is large and the complete list of elements is not easily available.

Stratified random sampling is a technique where the population is divided into strata or subgroups based on certain characteristics and a random sample is chosen from each stratum.

Cluster sampling involves dividing the population into clusters or groups and then selecting a random sample of clusters. The elements within each selected cluster are then included in the sample.

Convenience sampling is a non-probability sampling method where the sample is chosen based on convenience and availability. This method is often used in situations where it is difficult or expensive to obtain a random sample.

The width of the rectangle is 9 meter.

Now, According to the question:

The perimeter of a rectangle is defined as the sum of all the sides of a rectangle. For any polygon, the perimeter formulas are the total distance around its sides. In case of a rectangle, the opposite sides of a rectangle are equal and so, the perimeter will be twice the width of the rectangle plus twice the length of the rectangle and it is denoted by the alphabet “p”.

Now, Solving the problem:

Perimeter of rectangle is 50 meter sq.

Length of the rectangle(L) is 16 meter.

We have to find the width (W) of the rectangle.

We know that,

Perimeter of rectangle is = 2 (L + W)

50 = 2(16 + W)

50 = 32 + 2W

2W = 50 - 32

2W = 18

W = 18/2

Now, we can evaluate the improper integral of f(x) from 1 to infinity:
integral^infinity_1 1/(2x + 8) dx. Since, the improper integral diverges, the series also diverges by the Integral Test. Therefore, the answer is b. diverges.

Your answer: b. diverges

To apply the Integral Test, we first need to confirm that the function f(x) = 1/(2x + 8) is continuous, positive, and decreasing on the interval [1, ∞). Since the function meets these conditions, we can apply the Integral Test.

Now, let's evaluate the integral:
∫[1,∞] (1/(2x + 8)) dx

To solve this, we can use the substitution method:

let u = 2x + 8, so du = 2 dx. Now, when x = 1, u = 10, and when x → ∞, u → ∞.
Now, the integral becomes:
(1/2) ∫[10,∞] (1/u) du

This is an improper integral, and its form is a p-series where p = 1. We know that a p-series converges if p > 1 and diverges if p ≤ 1. In this case, p = 1, so the integral diverges.
Since the integral diverges, by the Integral Test, the given series also diverges.

dude what type of question is this

If your index is used to access the indexed variables of the array has the value of a non-existent index, this is called Index out-of-bounds.

What is Index out-of-bounds?

An index out-of-bounds error happens when an index used to access the indexed variables of an array or a list has a value that is outside the valid index range. This signifies that the index is either less than zero or larger than or equal to the array or list's size.

Assume we have a 5-element array and want to retrieve the entry at index 7. Because the array only has 5 entries, index 7 is out of limits, and attempting to access it will result in an index out-of-bounds error.

An index out-of-bounds error can create unpredictability in a program, such as reading or writing to memory regions not intended for usage by the program, causing the program to crash. To prevent index out-of-bounds issues, make sure the index used to access the array or list is inside the valid index range.

Therefore, if your index is used to access the indexed variables of the array has the value of a non-existent index, this is called Index out-of-bounds.

If your index is used to access the indexed variables of the array has the value of a non-existent index, this is called an "out-of-bounds" error. This means that the index being used to access the array is either too high or too low, and there is no corresponding variable at that index.

This can cause unexpected behavior in a program and can even cause it to crash. It is important to always ensure that your indexes are within the bounds of the array and that the values being used are valid.
When an index is used to access the indexed variables of an array, but the value of the index is not within the valid range of indices for that array (i.e., the index is for a non-existent element), this situation is called an "out-of-bounds" access.

When you attempt to access an element using an out-of-bounds index, you might encounter unexpected behavior or errors, as the program tries to access a memory location that is not part of the array. To avoid this, always ensure that the index value is within the valid range of indices for the given array.

its division just add 440 plus 2.75$ Then when u add them divide whatever u get by 5

The number of calendars must be sold to keep the cost of printing under $5 per calendar is 196.

Given that, the total cost of printing the calendar is $440 plus an additional charge of $2.75 per calendar.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of calendars be x.

An additional charge of $2.75 per calendar

= 2.75x

Now, (440+2.75x)/x =5

⇒ 440+2.75x=5x

⇒ 2.25x=440

⇒ x=440/2.25

Step-by-step explanation:

assuming the diigram attached is similar to the one required to complete the question,

From the diagram

Area of the window = Area of the rectangle+ Area of the semi circle.

A = lw+πr²/2................ Equation 1

Where A = area of the window, l = length of the rectangle, w = width of the rectangle, r = radius of the semi circle.

From the diagram,

Given: l = 4 ft, w = 2 ft, r = w/2 = 2/2 = 1 ft.

Constant: π = 22/7

Substitute these values into equation 1

A = (4×2)+(22/7×1²/2)

A = 8+1.57

A = 9.57 ft²
