What is the square root of 99 simplified?
Step-by-step explanation: To simplify the square root of 99, first create a factor tree that has 2 branches.
99 factors as 11 × 9 and 9 factors as 3 × 3.
Since we have a pair of 3's in our factor tree, a 3 can come out of the radical. Since we have a 11 that doesn't match up, it stays inside the radical and this gives us the answer of [tex]\sqrt[3]{11}[/tex].
I have also attached my work in the image provided.
The square root of 99, when simplified as much as possible, is approximately 9.94987437.
We have,
The square root of a number is a value that, when multiplied by itself, gives the original number.
In the case of the square root of 99, there is no whole number that can be multiplied by itself to result in 99.
Therefore, the square root of 99 is an irrational number.
To find an approximate value for the square root of 99, we can use a calculator or mathematical methods.
The square root of 99 is approximately 9.94987437.
This means that when we multiply 9.94987437 by itself, we get a value close to 99.
Since 9.94987437 cannot be simplified further as a whole number or a simplified radical, it is the most accurate representation of the square root of 99.
Thus,
The square root of 99, when simplified as much as possible, is approximately 9.94987437.

Answer: (1) The correct option is B. (2) he correct option is (C). The correct option is (A).
Explanation:
(1)
In the graphs the x-axis represents the time and the y-axis represents the height.
From given figure 1 it is noticed that the height is consistently increases as the time increases but not in the same proportion.
Because the points are not lies on a single straight line, it means the height increases but not in the same rate.
Therefore, the correct option B.
(2)
From figure 2 it is noticed that at initial state the height decreases after that height increases.
The option 1 represent the increase at constant rate, option 2 represent the increase in height but not at constant rate and option 3 represents the fluctuation in height.
Therefore the correct option is C.
(3)
From figure 3 it is noticed that all the pints lies on a single straight line, therefore the height increases at a constant rate.
So, the correct option is A.

A diver descends to a location of −5014 meters relative to the surface of the water. He then descends another 1012 meters.
What is the diver’s final location relative to the surface of the water?
Enter your answer as a simplified mixed number in the box.
Answer: Using operations with fractions, the diver's final location is:
- 60 3/4 meters relative to the surface of the water (60 3/4 meters below the surface of the water).
Solution:
Initial location: -50 1/4 meters
He descends another 10 1/2 meters: -10 1/2 meters
Final location = Initial location - 10 1/2 meters
Final location = - 50 1/4 meters - 10 1/2 meters
Final location = - (50+10) (1/4+1/2) meters
Final location = - 60 [(1)(1)+2(1)]/4 meters
Final location = - 60 (1+2)/4 meters
Final location = - 60 3/4 meters

Answer:
Annual income for all 150 employees at a local high school
Step-by-step explanation:
The normal distribution is also called the Gaussian distribution. It is the most common type of distribution for statistical analysis. The normal distribution is based on a probability distribution. The data near the mean are more frequent than the data away from the mean. It is based on two parameters: the mean and the standard deviation.
As per options, option A which states ‘annual income for all 150 employees at a local high school’ the data is within the standard deviation.

With a tail wind, a plane traveled 840 miles in 3hrs. With the same wind as a head wind, the return trip took 30 minutes longer. Find the plane's airspeed(in still air) and the wind speed....
So lost smh
To find the plane's airspeed (in still air) and wind speed, we can use the concept of relative velocity. By setting up a system of equations using the distances and times for the outbound and return trips, we can solve for the values of the airspeed and wind speed. Solving these equations, we find that the plane's airspeed is 230 mph and the wind speed is 70 mph.
Explanation:To find the plane's airspeed and wind speed, we can use the concept of relative velocity. Let's assume the plane's airspeed (in still air) is P mph and the wind speed is W mph.
On the outbound trip, with a tailwind, the plane's groundspeed (the speed relative to the ground) will be the sum of its airspeed and the wind speed: P + W mph. Since the distance traveled is 840 miles and the time taken is 3 hours, we have the equation: Distance = Speed * Time, where Speed is the groundspeed. Therefore, we can write the equation as: 840 = (P + W) * 3.
On the return trip, with the same wind as a headwind, the plane's groundspeed will be the difference between its airspeed and the wind speed: P - W mph. As it took 30 minutes longer, the time taken will be 3 hours + 0.5 hours = 3.5 hours. Using the same equation, we have: 840 = (P - W) * 3.5.
Now we have a system of equations, which we can solve to find the values of P and W. Solving these equations, we get:
Airspeed (in still air) = 230 mph
Wind speed = 70 mph

Find measure of angle d A. 122 degrees B. 61 degrees C. 238 degrees D. Not enough information
To find the measure of angle d, you can use the dot product formula and inverse cosine function.
Explanation:To find the measure of angle d, we need to consider the given information about vectors A and B. The vector A is represented as (122 cm, <145°) and the vector B is represented as (110 cm, <270°). The angle between two vectors can be found using the dot product formula: cos(theta) = A · B / (|A| * |B|). So, we can calculate the dot product and magnitude of vectors A and B, and then use the inverse cosine function to find the angle between them. The measure of angle d is __ degrees.

To graph the linear equation -5x+2y=11, choose x values and solve for y to find points for plotting. Three example points are x = 0, 2, and -5 with y values of 11/2, 8, and 21 respectively.
Explanation:Graphing the Linear Equation -5x + 2y = 11:
To find points, we can choose values for x and then solve for y.Choose x = 0, x = 2, x = -5 as examples.For x = 0, y = 11/2; for x = 2, y = 8; for x = -5, y = 21.

Final answer:
To find the number of tiger fish per aquarium, divide the total number of fish (24) by the number of aquariums (3), resulting in 8 tiger fish per aquarium.
Explanation:
The question asks us to determine how many tiger fish are in each aquarium if a pet store has 24 tiger fish and 3 aquariums, with each aquarium having the same number of fish.
To find the answer, we need to divide the total number of tiger fish by the number of aquariums:
Total number of tiger fish = 24
Number of aquariums = 3
We calculate the number of fish per aquarium by performing the division 24 ÷ 3, which equals 8. Therefore, there are 8 tiger fish in each aquarium.
What is the point slope form of the line with slope −1/4 that passes through the point (−2, 9) ?
y+9=−14(x−2)
y−2=−14(x+9)
y+2=−14(x−9)
y−9=−14(x+2)
Answer:
Step-by-step explanation:
Point slope form of the equation with point (a,b) and slope m is given by this equation
y-b=m(x-a)
Here we are given that the slope is -1/4 so m= -1/4
and the point is (-2,9) so a =-2 and b =9
Hence plugging the values in the equation we get
y-9 = -1/4 (x-(-2))
y -9 =-1/4 (x+2)
