The temperature of dry ice is −109.3°f−109.3°f. this is 184.9°f184.9°f less than the outside temperature. write and solve an equation to find the outside temperature tt (in degrees fahrenheit).
Final answer:
To find the outside temperature T when the temperature of dry ice is -109.3°F, and it is 184.9°F less than the outside temperature, we simply need to add those two numbers. The outside temperature T is found to be 75.6°F.
Explanation:
The student is asked to find the outside temperature T given that the temperature of dry ice is −109.3°F. The temperature of dry ice is 184.9°F less than the outside temperature. To find the outside temperature, we can set up the following equation:
T = (-109.3°F) + 184.9°F
Now, we simply add the two numbers to solve for T:
T = 75.6°F
The calculation shows that the outside temperature T is 75.6°F.

f(6)=___
let f(x)=3x^2-x+2 and g(x)= 5x^2-1. find f(g(x))
Answer:
15x^4-5x^2+1
Step-by-step explanation:
g(x)=5x^2-1 and f(x)=3x^2-x+2
f(g(x))would mean that g(x) would be x in f(x).
So f(g(x) would be 15x^4-3-5x^2+1+2
simplified would be 15x^4-5x^2+1

The root x = 1 has multiplicity 3 for the function f(x)=x^3-x^2-x+1. True or false
The root x = 1 has multiplicity 3 for the function f(x) = x³ - x² - x + 1.
Explanation:The statement is true.
A root of a polynomial function has a multiplicity equal to the number of times it appears as a factor in the polynomial. In this case, the root x = 1 appears three times as a factor in the function f(x) = x³ - x² - x + 1. Therefore, it has a multiplicity of 3.

John has on his shelf four books of poetry, four novels, and two reference works. suppose from these ten books, we were to pick two books at random. what is the probability that we pick one novel and one reference work? (a) 1/2
The probability isf 8/45.
Probability calculation:
Calculate the total number of ways to pick 2 books from the 10 books, which is 10 choose 2 = 45.
Calculate the number of ways to pick 1 novel and 1 reference work, which is 4 choose 1 for novels * 2 choose 1 for reference works = 8.
Divide the number of favorable outcomes by the total outcomes to get the probability: 8/45 = 8/45.

There are 15 tennis balls in a box, of which 9 have not previously been used. three of the balls are randomly chosen, played with, and then returned to the box. later, another 3 balls are randomly chosen from the box. find the probability that none of these balls has ever been used
Final answer:
The probability that none of the balls have been previously used is 20.96%.
Explanation:
To find the probability that none of the three balls selected have ever been used, we first calculate the probability of selecting a ball that has not been used each time.
Initially, there are 15 balls in total, out of which 9 have not been used. So, the probability of selecting a ball that has not been used on the first draw is 9/15.
After the first draw, the number of balls in the box remains the same, but the number of unused balls decreases to 8. So, the probability of selecting a ball that has not been used on the second draw is 8/15.
Similarly, for the third draw, the probability of selecting a ball that has not been used is 7/15.
Since the balls are chosen randomly and returned to the box after each draw, the probabilities are independent. Therefore, to find the probability that none of the balls have ever been used, we multiply the probabilities of each draw:
(9/15) x (8/15) x (7/15) = 0.2096, or approximately 20.96%.

the recommended dosage of a drug for pediatric patients is 200 mg per kilogram of a patients weight if janine weights 76lb how much of the drug should she get
To determine the dosage of a drug for Janine, who weighs 76 pounds, convert her weight to kilograms and then multiply by the recommended dose per kilogram. The conversion and the dose calculation led to approximately 6894.6 mg of the drug.
The recommended dosage of a drug for pediatric patients is 200 mg per kilogram of the patient's weight. To calculate the dosage for Janine, who weighs 76 pounds, we first need to convert her weight from pounds to kilograms, as dosages are usually measured in metric units. To do so, we use the conversion factor where 1 kilogram equals 2.20462 pounds.
First, we convert Janine's weight to kilograms:
[tex]\frac{76}{2.20462}[/tex] lb/kg = 34.473 kg roughly.
Next, we calculate the total dosage needed in milligrams by multiplying her weight in kilograms by the dosage per kilogram:
34.473 kg * 200 mg/kg = 6894.6 mg.
Therefore, Janine should receive a dose of approximately 6894.6 mg of the drug.

What is the value of x in the equation below?
–3 – (–8) – (–2) = x
If I'm not mistaken (it's been a while since I was in school) I believe the answer is x=11.
what is the solution to this equation? 4x^2+98=0
Follow below steps;
The equation to solve is 4x² + 98 = 0.
1. Subtract 98 from both sides to get 4x² = -98.
2. Divide by 4 to obtain x² = -24.5.
3. Take the square root, remembering that √(-1) = i, so x = ±√24.5i.

Which of the following is the linear parent function
Answer:
Option C is correct linear parent function.
Step-by-step explanation:
We need to choose from the option as a linear parent function.
We will look each option and explain each one.
Option A: [tex]f(x)=|x|[/tex]
Here we have absolute sign on x. It is parent function of absolute function.
Option B: [tex]f(x)=x^2[/tex]
Here we have square on x. It is parent function of quadratic or parabola.
Option C: [tex]f(x)=x[/tex]
It is parent function of linear because exponent of x is 1 and coefficient of x is 1.
Option D: [tex]f(x)=2x[/tex]
It is linear function but not parent because coefficient of x is not 1.
Hence, Option C is correct linear parent function.
Which angle is the included angle for DE¯¯¯¯¯ and FE¯¯¯¯¯ ?
∠D
∠E
∠F
Answer: ∠E
Step-by-step explanation:
The included angle for [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] is [tex]\angle{E}[/tex].
The included angle for any two lines or line segments is represented by the common vertex point.
For example : The included angle for [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] is [tex]\angle{B}[/tex] [Since B is the common end point in [tex]\overline{AB}[/tex] and [tex]\overline{BC}[/tex] ]
Similarly, the included angle for [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] is [tex]\angle{E}[/tex] (Since E is the common vertex in [tex]\overline{DE}[/tex] and [tex]\overline{FE}[/tex] )
