Write each set builder notation as interval notation. Do not include spaces in your answer. Please type out the word "infinity".
{r | -3 < r < 4}
Answers
The interval notation (-3, 4) represents the set of real numbers r that are greater than -3 and less than 4, excluding -3 and 4.
The set builder notation {r | -3 < r < 4} can be expressed in interval notation as (-3, 4).
In interval notation, the parentheses indicate that the endpoints, -3 and 4, are not included in the set.
The interval (-3, 4) represents all the real numbers r that are greater than -3 and less than 4, but not including -3 and 4.
It can also be visualized on a number line as an open interval between -3 and 4, where the endpoints are not filled in.
The interval (-3, 4) can be interpreted as a range of values for r. Any real number between -3 and 4, excluding the endpoints, would satisfy the given set builder notations.
For example, -2, 0, and 3 are all included in the interval (-3, 4), but -3 and 4 themselves are not part of the set.

The number of times the students on your floor order pizza in a week, population.
A population is a complete set of individuals or objects that share common characteristics. It is an entire group of people, animals, plants, or objects that can be studied. A population can also be a group of people living in a certain geographical area.
A sample is a subset of a population. It is a smaller group of individuals or objects drawn from the population that are used to make inferences about the population as a whole.
A sample is used in statistical analysis to estimate population characteristics, such as mean, median, and variance. The accuracy of the estimates depends on the size and representativeness of the sample.

Evaluate\(g(x) = \frac{x^2 - 6}{3x+10}\)\(g(4) = \frac{4^2 - 6}{3(4) + 10}\)\(g(4) = \frac{16 - 6}{12 + 10}\)\(g(4) = \frac{10}{22}\)Simplify

Find a polynomial function f(x) of degree 3 with zeros, 2, -3 , 5 and f(3)=6
Answers
A polynomial function f(x) of degree 3 with given zeros, 2, -3 , 5 and condition f(3)=6 is given by f(x) = -1/2 (x-2)(x+3)(x-5).
Degree of the polynomial function is equal to 3.
Zero's of the polynomial function is equal to 2, -3 , 5 .
And f(3) = 6
If 2, -3, and 5 are zeros of f(x), then we can write function as,
f(x) = a(x-2)(x+3)(x-5)
where a is some constant.
To determine the value of a, we can use the fact that f(3) = 6.
Substituting x = 3 into the equation above, we get,
f(3) = a(3-2)(3+3)(3-5)
= -12a
Here we have,
f(3) = 6, so we can set these two expressions equal to each other and solve for a,
⇒ -12a = 6
⇒ a = -1/2
Now we can substitute this value of a back into the equation for f(x) that we found earlier,
⇒ f(x) = -1/2 (x-2)(x+3)(x-5)
Therefore, a polynomial function f(x) of degree 3 with zeros 2, -3, 5, and f(3) = 6 is equal to f(x) = -1/2 (x-2)(x+3)(x-5).

A doctor may prescribe Keflex for an ear infection. One capsule = 0.250 g of Keflex. The recommended daily dose for a child is (40.0mg of Keflex)/(kg that the child weighs). How many Keflex capsules would a 69-pound child take for one daily dose? (Round to the nearest whole number of capsules) Given: 1 pound = 0.453592 kg
Answers
Answer:
5 capsules
Step-by-step explanation:
A doctor may prescribe Keflex for an ear infection. One capsule = 0.250 g of Keflex. The recommended daily dose for a child is (40.0mg of Keflex)/(kg that the child weighs).
Step 1
We convert the capsules form grams to milligrams
1 gram = 1000 milligrams
0.250grams = x
Cross Multiply
x = 0.250 × 1000 milligrams
x = 250 mg
Hence, 1 capsule = 250 mg
How many Keflex capsules would a 69-pound child take for one daily dose? (Round to the nearest whole number of capsules) Given: 1 pound = 0.453592 kg
The recommended daily dose for a child is (40.0mg of Keflex)/(kg that the child weighs).
The child weighs 69 pounds
1 pound = 0.453592 kg
69 pounds = x kg
Cross Multiply
x kg = 69 × 0.453592kg
x kg = 31.297848kg
Hence,
1 kg= 40.0 mg
31.297848 kg = x
x = 31.297848 × 40.0mg
x = 1251.91392mg
Therefore, the child would take 1251.91392 mg
From the first calculation we know that:
1 capsule = 250 mg
250mg = 1 capsule
1251.91392 mg = x capsules
250mg × x = 1251.91392 mg × 1 capsule
x = 1251.91392 mg/250mg
x = 5.00765568 capsules
Approximately = 5 capsules
Hence, a child that weighs 69 pounds takes 5 capsules of keflex

An ant colony is built by 200 ants. The number of ants triples each week. How many ants will be in the colony at the end of the eighth week?
Answers
N = N0 * 3^t
where N is the final number of ants, N0 is the initial number of ants, 3 is the rate of growth (since the number of ants triples each week), and t is the number of weeks.
We are given that there are initially 200 ants, so N0 = 200. We want to find N at the end of 8 weeks, so t = 8. Substituting these values into the formula, we get:
N = 200 * 3^8
N = 200 * 6561
N = 1,312,200
Therefore, at the end of the eighth week, there will be 1,312,200 ants in the colony.

find the range of this equation
Answers
The range of the given equation is [-1, infinity).
We are given that;
Equation y= underroot(x+5)
Now,
The domain of this equation is the set of x values that make the expression under the square root non-negative.
That is, x+5 >= 0, or x >= -5. So the domain is [-5, infinity).
The range of this equation is the set of y values that are obtained by plugging in the domain values into the equation. Since the square root function is always non-negative, and we are subtracting 1 from it, the smallest possible value of y is -1, when x = -5. As x increases, y also increases, and there is no upper bound for y.
Therefore, by the range the answer will be [-1, infinity).

Using log evaluate 3^x=10
Answers
Answer:
x ≈ 2.09590327429
Step-by-step explanation:
You want the solution to 3^x = 10 using logarithms.
LogsTaking logarithms of both sides of the given equation, we have ...
x·log(3) = log(10)
Dividing by the coefficient of x gives ...
x = log(10)/log(3)
x ≈ 2.09590327429
__
Additional comment
If the logarithm to the base 10 is used, then this becomes ...
x = 1/log₁₀(3)
The meaning of "log( )" varies with the context. In high-school algebra, it usually means "log₁₀( )". In other contexts, it may mean "ln( )", the natural logarithm.
For the purpose here, it doesn't matter what base the logarithms have, as long as log(10) and log(3) are to the same base.
<95141404393>
The approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.
To evaluate the equation 3^x = 10 using logarithms, we can take the logarithm of both sides of the equation. The most commonly used logarithm is the base 10 logarithm, also known as the common logarithm (log).
Taking the log of both sides, we get:
log(3^x) = log(10)
Now, we can apply the logarithmic property that states log(a^b) = b * log(a). Applying this property to the left side of the equation:
x * log(3) = log(10)
Next, we can divide both sides of the equation by log(3) to isolate the variable x:
x = log(10) / log(3)
Using a calculator, we can evaluate the right side of the equation:
x ≈ 1.46497
Therefore, the approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.

Round to the nearest minute.
Answers
It will take approximately 6.1 minutes to fill the pool to a depth of 20 cm at the given fill rate.
How to solve for the time it will take to fill the poolFind the radius of the pool:
Since the diameter is 115 cm, the radius (r) will be half of that:
Radius (r) = Diameter / 2
r = 115 cm / 2
r = 57.5 cm
Calculate the volume of the pool when filled to a depth of 20 cm:
Since the pool is round and assuming it has a cylindrical shape, we can use the formula for the volume of a cylinder:
Volume = π × r² × h
where π (pi) is approximately 3.14159, r is the radius, and h is the height (or depth, in this case).
Volume = 3.14159 × (57.5 cm)² × 20 cm
Evaluate the volume:
Volume ≈ 3.14159 × 3306.25 cm² × 20 cm
Volume ≈ 3.14159 × 66125 cm³
Volume ≈ 207354.2 cm³
Calculate the time it takes to fill the pool to a depth of 20 cm:
We are given that the hose fills the pool at a rate of 34,000 cm³ per minute. To find out how long it will take to fill the pool, we can use the following formula:
Time = Volume / Fill Rate
Time ≈ 207354.2 cm³ / 34,000 cm³/min
Time ≈ 6.1 minutes
It will take approximately 6.1 minutes to fill the pool to a depth of 20 cm at the given fill rate.
