Answer:

Find the area of a cardboard box with a length of 9 inches and a width of 4 inches.

Step-by-step explanation:

9 in × 4 in = 36 in²

-6.625 or -6.63 rounded up

Answer: B) 3(9+4)

Step-by-step explanation:

B is the correct answer because of the PEMDAS rule telling in what order to solve an expression with more than one operation. (parenthesis, exponents, multiplication, division, addition, subtraction). Therefore, with parentheses coming before multiplication in the PEMDAS rule it would be adding 9+4 and then mulriplying it by three.

Answer:

A) 20.82 > 20.55

Step-by-step explanation:

Hopefully, your issue is with the symbols (< vs >) rather than actually determining which number is larger or smaller.

The wide-open end of the symbol (the left side, in the case of >) indicates the larger (more positive) number.

So, the meanings of the symbols are ...

> — "is greater than"

< — "is less than"

The only true statement of those listed is ...

20.82 is greater than 20.55, or 20.82 > 20.55 . . . . selection A

_____

When writing number comparisons, I like to use the < symbol, because it puts the numbers in number-line order. That is, the smaller (or more negative) number is on the left, just as it is on a number line.

You trade the places of the numbers when changing the symbol. For example, answer choice A could be rewritten as ...

20.55 < 20.82

You know that 20.55 is to the left of 20.82 on the number line, so you know this statement is true.

Answer:

  area of triangle: 1.2975

  area of circle: π ≈ 3.1416

Step-by-step explanation:

The side length (B) is used to compute the perimeter of the triangle. For the 3-sided triangle, the perimeter is ...

  P = 3B = 3·1.73 = 5.19

The "height" (H) measured from the center of the circle to the middle of one side is called the "apothem" (a). The area of the triangle (A) is the product of half that and the perimeter:

  A = (1/2)aP = (1/2)·0.5·5.19 = 1.2975 . . . . . . square units

(x+4)²+(y-3)²=2²;

it means r²=2²; ⇒ r=2.

Answer:

x = 36

Step-by-step explanation:

Multiply both sides of the equation by the inverse of the coefficient of x.

(2/1)·(1/2)x = (2/1)·18 . . . . . . . coefficient of x is 1/2, so we multiply by 2/1

x = 36

_____

This "multiplicative inverse" is also called the reciprocal. It has the property that when multiplied by the coefficient of x, the result is 1, the multiplicative identity element. So, your equation becomes ...

1·x = 36

The property of the multiplicative identity element is that anything multiplied by it is that thing. So, 1x = x, and your equation becomes

x = 36

This is the solution you're looking for.

The answer is 36 !!!!!

Answer:

g(x)

Step-by-step explanation:

y-intercept is the y cutting point, at x = 0.

1. f(x)

This will be an exponential function that starts from 6 and moves upward exponentially. So y-intercept is 6.

2. g(x)

We can see that at x = 0, the value of the function is 2, so that is the y cutting point. So y-intercept is 2.

3. h(x)

We can clearly see from the graph that the y-cutting point is at 4. So y-intercept is 4.

4. j(x)

We can plug in x = 0 into the equation to find y intercept.

[tex]j(x)=10(2)^x\\=10(2)^0\\=10(1)\\=10[/tex]

So y - intercept is 10.

Smallest y-intercept is that of g(x).

Answer:

-14

Step-by-step explanation:

Put -1 where x is in the definition of g(x) and do the arithmetic.

2g(-1) = 2(2·(-1) -5) = 2(-2-5) = 2(-7) = -14

The polynomial remainder theorem gives an immediate answer. It says that the remainder upon dividing [tex]p(x)[/tex] by [tex]x-c[/tex] is exactly [tex]p(c)[/tex]. In this case [tex]q=x+1\implies c=-1[/tex], and we have

[tex]k=p(-1)=(-1)^{999}-(-1)^{100}+3(-1)^9-5=-1-1-3-5=-10[/tex]

Answer:6√2  8-9 Irrational number

Answer:

64 and 81, 8 and 9, irrational

Answer:

x > 2

Step-by-step explanation:

The inequality has constants and variables on both sides. It is convenient to find the variable term with the smallest (most negative) coefficient. Add the opposite of that term to both sides of the inequality.

2x -3 +5x > 11 -5x +5x . . . . added 5x

7x -3 > 11 . . . . . . . . . . . . . . . simplify

Now, find the constant on the side of the inequality that has the variable term. Add the opposite of that constant to both sides.

7x -3 +3 > 11 +3 . . . . . added 3

7x > 14 . . . . . . . . . . . . simplify

Finally, divide by the coefficient of x. It is positive, so we do not need to do anything to the relation symbol.

x > 14/7 . . . . . . . . . . divided by 7

x > 2 . . . . . . . . . . . . simplify . . . . This is your solution.

Final answer:

To determine the function's behavior over an interval, compare the y-values as the x-values increase. It could be increasing, decreasing, constant, or changing direction. Choose the description that matches the graph's movement over the given interval.

Explanation:

To determine how the function behaves over the interval [2, 6], we must look at the description of the graph presented. If during the interval the function is always moving upwards as the x-values increase, then it is increasing. If it moves downwards, it is decreasing. If the graph stays at the same level without moving up or down, then it would be constant. If the graph changes its direction, from either increasing to decreasing or vice versa, then it would be described as decreasing to increasing or increasing to decreasing, accordingly. Given these possibilities, the student should match the behavior of the graph with one of these descriptions.

Step-by-step explanation:

f(x) = x^2 does not pass the horizontal line test (a horizontal line intersects its graph in two places), so its inverse does not pass the vertical line test. The inverse is not a function.

Answer:

A, B, E

Step-by-step explanation:

Permutations are involved when order matters, as in lane assignment, passwords, and seating charts.

When the end result is a "group of 10 students", "3 employees", or "4 cashiers", clearly order does not matter. One student, employee, or cashier is as good as another in these cases.

Using it's definition, it is found that these following situations involve permutations:

A) Determining how many different ways 7 runners can be assigned lanes on a track for a race.

B) Determining how many 5-letter passwords can be made using the word "graph."

E) Determining how many different seating charts can be made placing 6 people around a table.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

Answer:

your choice is correct: hyperbola

Step-by-step explanation:

When the plane intersects both naps of the cone, the result is a hyperbola. When only a single nap is intersected (and the plane is parallel to the edge of the cone), the curve is a parabola. An ellipse or circle results when the plane crosses both edges of the cone on the same nap.

Answer:

ellipse

Step-by-step explanation:

The length of one side of the stage is 17 feet.

To find the length of one side of a square, we take the square root of the area because the area of a square is equal to side length squared.

So, the calculation is as follows:

Area of square = side imes side

289 square feet = side imes side

Therefore, side =√289

Calculating the square root of 289 gives us the side length:

side = 17 feet

So, to determine the length of one side of a square stage with an area of 289 square feet, we calculate the square root of the area, which results in 17 feet.

To get at least a 50% probability of getting at least three heads, you must flip a fair coin at least four times.

To calculate the minimum number of times a fair coin must be flipped before there is at least a 50% probability of getting at least three heads, we can use the concept of probability. Let's assume that flipping a coin is a binary event with two possible outcomes: heads (H) or tails (T).

The probability of getting three or more heads in one flip is zero, since we can only get a maximum of two heads in one flip. However, we can calculate the probability of getting three or more heads in a series of flips.

The probability of getting at least three heads in one flip is zero, but we can calculate the probability of getting at least three heads in two flips, three flips, four flips, and so on. We continue calculating the probability until we find the number of flips that gives us a probability of at least 50%.

Using this method, we find that we need to flip the coin at least 4 times to have a probability of at least 50% of getting at least three heads. This means that after flipping the coin four times (or more), there is a better than 50% chance of getting at least three heads.
