As a result, the sector QPR's area is roughly 60.3 m².

We must apply the following algorithm to determine the sector QPR's area:

Sector QPR area = θ/360°(r²)

where r is the circle's radius, is a constant equal to roughly 3.14, and is the sector's angle in degrees.

We can substitute these numbers into the calculation and simplify it because the angle in this example is provided as 80 degrees and the radius r as 8 meters:

QPR sector area = (108/360)(8)²

QPR sector area = (0.3)(64)

QPR sector area = 19.2

QPR sector area = 19.2

QPR sector area = 60.318°

As a result, the sector QPR's area is roughly 60.3 m².

The distance between points a and b in a triangle shape is 70.17 m

Triangle is a special shape that has the rule that the total angle in the triangle should be 180⁰

A + B + C = 180⁰

where A, B, and C are the angles in the triangle.

Moreover, the triangle has a sine rule which shows the relationship between sides and angles. It is given as :

a/sinA = b/sinB = c/sinC

From the question above, we know that :

A = 70.5⁰

C = 38.83⁰

b = 105.6 m

It is needed to determine the angle of B

A + B + C = 180⁰

70.5⁰ + B + 38.83⁰ = 180⁰

B = 70.67⁰

Then, determine the distance between points a and b (c) by using the sine rule

b/sinB = c/sinC

105.6 / sin(70.67⁰) = c / sin(38.83⁰)

105.6 / 0.94 = c / 0.63

c = 70.17 m

Hence, the distance between points a and b is 70.17 m

There will be a total of 40 pyramids made. The employee wants to stack the cans into pyramids of 10 cans each. So, the number of cans in each pyramid is 10.

To find out how many pyramids can be made from 400 cans of soup, we need to divide the total number of cans by the number of cans in each pyramid. In this case, the employee wants to stack the cans into pyramids of 10 cans each.
So, we can use the following formula:
number of pyramids = total number of cans / number of cans in each pyramid
Plugging in the values we have:
number of pyramids = 400 / 10
number of pyramids = 40
Therefore, there will be a total of 40 pyramids made.

To further explain the solution, we can break it down into steps.
Step 1: Determine the number of cans in each pyramid
Step 2: Calculate the total number of pyramids
To find out how many pyramids can be made from 400 cans of soup, we need to divide the total number of cans by the number of cans in each pyramid.
number of pyramids = total number of cans / number of cans in each pyramid
Plugging in the values we have:
number of pyramids = 400 / 10
number of pyramids = 40
Therefore, there will be a total of 40 pyramids made.

8 is 2×2×2.

Doubling a number is the same as multiplying ×2.

So maybe you could take the 9 and double it, 18.

Double it again, 36.

Double it again, 72.

Or anyway that you can "take apart" 8 and 9 in smaller numbers and rearrange, because you can multiply in any order.

For example, if you don't know your 8 or 9 times tables, but you know your 3 and 4 and 6 times tables:

8 is 4×2 and

9 is 3×3.

8×9 is the same as 2×3 and 4×3

6×12

which is 72.

Answer:

-3,-4.5

Step-by-step explanation:

The inverse tangent of 0.9 is approximately 42.0 degrees.

Therefore, the correct answer is option C: 42.0⁰.

The inverse tangent, also known as arctangent, is a trigonometric function that gives the angle whose tangent is a given number. In this case, we want to find the inverse tangent of 0.9.

Using a calculator or reference table, we can find that the inverse tangent of 0.9 is approximately 42.0 degrees.

To understand why this is the case, we can consider the definition of the tangent function. The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right triangle. The inverse tangent function reverses this relationship, giving us the angle when we know the tangent value.

In the case of 0.9, we can imagine a right triangle where the length of the side opposite the angle is 0.9 and the length of the side adjacent to the angle is 1. The inverse tangent of 0.9 tells us the angle that satisfies this relationship.

So, the inverse tangent of 0.9 is approximately 42.0 degrees.

Therefore, the correct answer is option C: 42.0⁰.

In Mathematics, a domain is the set of all real numbers for which a particular function is defined.

Additionally, the horizontal extent of any graph of a function represents all domain values and they are read and written from smaller to larger numerical values, and from the left of a graph to the right.

By critically observing the graph, we can reasonably and logically deduce the following domain:

For the equation 1/2 = 1/3 - |x + 3|/(6 + x), the solution value for x is obtained as x = -12/5.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The given equation can be written as -

1/2 = 1/3 - |x + 3|/(6 + x)

To solve for x, we can first isolate the absolute value term by subtracting 1/3 from both sides -

1/2 - 1/3 = - |x + 3|/(6 + x)

Next, we can multiply both sides by the denominator (6 + x) to eliminate the fraction -

(6 + x)(1/2 - 1/3) = -|x + 3|

Simplifying the left-hand side -

(6 + x)(1/2 - 1/3) = (6 + x)(1/6) = (x + 6)/6

So the equation becomes -

(x + 6)/6 = -|x + 3|

Now we can solve for x in two cases, depending on whether x + 3 is positive or negative -

Case 1: x + 3 ≥ 0

In this case, |x + 3| = x + 3, so the equation becomes -

(x + 6)/6 = -(x + 3)

Multiplying both sides by 6 -

x + 6 = -6x - 18

Simplifying -

7x = -24

x = -24/7

But we need to check that this value satisfies the condition x + 3 ≥ 0. Since -24/7 is negative, it doesn't satisfy this condition, so we discard this solution.

Case 2: x + 3 < 0

In this case, |x + 3| = -(x + 3), so the equation becomes -

(x + 6)/6 = x + 3

Multiplying both sides by 6 -

x + 6 = 6x + 18

Simplifying -

5x = -12

x = -12/5

This solution satisfies the condition x + 3 < 0, so it is a valid solution.

Therefore, the solution to the equation is x = -12/5.

Answer:

x = 2 and x = -1

Step-by-step explanation:

The zeroes of the function are found by setting g(x) equal to 0:

g(x) = (x - 2)(3x + 3) = 0

By the Zero Product Property, in order for this equation to be equal to 0, each of (x - 2) or (3x + 3) or both has to equal 0. So, set each equal:

x - 2 = 0

x = 2

3x + 3 = 0

3x = -3

x = -3/3 = -1

The zeroes are thus x = 2 and x = -1.

Confidence intervals are used to estimate a population parameter, such as the mean, based on a sample of data.

The width of the confidence interval reflects the degree of uncertainty in the estimate of the population parameter. The width of the confidence interval is directly proportional to the level of confidence that is desired.

A 90% confidence interval is less certain than a 99% confidence interval because it has a smaller degree of coverage. This means that there is a higher chance that the true population parameter is outside the 90% confidence interval than the 99% confidence interval. As a result, the width of the 90% confidence interval is smaller than the width of the 99% confidence interval.

In summary, a larger level of confidence (e.g., 99%) corresponds to a wider confidence interval, while a smaller level of confidence (e.g., 90%) corresponds to a narrower confidence interval.

Answer: 7/4.

Step-by-step explanation: To find the slope of a line, one must use the formula (y2-y1)/(x2-x1). In this case y2 is 2, y1 is -5, x2 is 4, and x1 is 0. We can plug this into the equation to get 7/4.

The lengths of the sides of the rectangular field so as to minimize the amount of fencing needed is 30 feet by 20 feet

Let x represent the length of the fence and y represent the width of the fence.

Since the area is 600, hence:

Area = length * width = x * y

600 = xy

y = 600/x

A fence divide the field in half and is parallel to one of the sides of the rectangle. Hence:

Amount of fencing needed (P) = x + x + y + y  + y = 2x + 3y

Amount of fencing needed (P) = 2x + 3(600/x) = 2x + 1800/x

To minimize the amount of fencing needed, dP/dx = 0, hence:

dP/dx = 2 - 1800/x²

2 - 1800/x² = 0

2 = 1800/x²

2x² = 1800

x² = 900

x = 30 feet

y = 600/x = 600/30 = 20 feet

Hence, the lengths of the sides of the rectangular field so as to minimize the amount of fencing needed is 30 feet by 20 feet
