Answer:
108 cubic units
Step-by-step explanation:
If X = 2 units, Y = 9 units, and Z = 6 units, then what is the volume of the rectangular prism shown above?
Volume of a rectangular prism XYZ = Length × Width × Height
= 2 unit × 9 unit × 6 unit
= 108 cubic units
What is the value of x in the equation shown below?
x3 + 1 = 9
Answer:
x = 7/3 or 2.33
Step-by-step explanation:
x3 + 1 = 8
x3 = 8 - 1
x3 = 7
x = 7/3 or 2.33
HOPE THIS HELPS YOU!! :)
Answer: x = 2
Step 1.
In order to solve this non-linear equation, we need to move all the terms to the left side.
In x³ + 1 = 9...
- term 1, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
Rewrite the equation like this: (x³ + 1) + (-1) = 9 + (-1)
Step 2.
Add x³ + 1 + (-1)
x³ + 1 + (-1) = 8
Now, x = 8.
Step 3.
In this non-linear equation, the variable needs to be isolated.
This is accomplished when both sides are exponentiated by the reciprocal of the variable's exponent, which in our example, 1/3 is equal to
Notice that since we exponentiated a simplified fraction with an odd denominator, only one solution has been created.
Rewrite the equation: [tex](x^3)^\frac{1}{3} =8^\frac{1}{3}[/tex]
Step 4.
We need to exponentiate the power.
The following rule is applied: [tex](A^B)^C=A^B^C[/tex]
According to the formula,
A = X
B = 3
C = 1/3
Rewrite the equation: [tex]x^3^\times^\frac{1}{3} =(2^3)^\frac{1}{3}[/tex]
Step 5.
We need to reduce this fraction, the 3 in x to the lowest terms.
This can be done by dividing out those factors that appear both in the numerator and in the denominator.
In our example, 3 is the common factor.
Rewrite the equation: [tex]x=2^\frac{3}{3}[/tex]
Step 6.
Lastly, we'll need to do the same thing as we did in step 5. Reduce the fraction in [tex]x=2\frac{3}{3}[/tex]. This can be done by dividing out those factors that appear both in the numerator and in the denominator.
Hence, the common factor is 3 since it occurs both in the numerator and the denominator.
Hence, x = 2.

A jet pilot flew a distance of 3,311 mi in 5 hour and 30 min. Find the planes average rate of speed. Please Help me! I would really appreciate it if someone helped me as soon as possible. Can you also explain how you got your answer?
Answer: 602 miles
Step-by-step explanation:
The average rate of speed is calculated by the formula;
= Distance / Time
You need to convert the time into hours. Time is 5 hours 30 mins.
Convert those minutes to hours:
1 hour is 60 minutes so 30 minutes would be:
= 30 / 60
= 0.5 hours
Total time = 5 hours + 0.5 hours
= 5.5 hours
Now go back to speed equation:
Speed = 3,311 / 5.5
= 602 miles

Step-by-step explanation:
After the translation of 2 units left, the function becomes f(x)=(x-2)³-(x-2)². Therefore, option A is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is g(x)=x³-x².
When the shape is moved towards the left by k units, then replace x with x - k.
The function shifted to the left 2 units.
So, the function is f(x)=(x-2)³-(x-2)²

The lengths of the sides of a triangle are given below. Classify the triangle as acute, obtuse, or right.
13, 14, 17
A. Acute Triangle
B. Obtuse Triangle
C. Right Triangle
Answer:
A. Acute TriangleStep-by-step explanation:
Lets verify with Pythagorean:
17² = 28913² + 14² = 169 + 196 = 365289 < 365The angle opposite to a greater side is less than 90° and the sum of the squares are close.
It means all three angles are less than 90°.
With this the triangle is acute.
Correct choice is A.
Can someone give me a definition of Measure of center? Also, some facts/properties about it, example, and a non-example. Please? Thanks!
Answer:
A measure of central tendency (measure of center) is a value that attempts to describe a set of data by identifying the central position of the data set (as representative of a "typical" value in the set). We are familiar with measures of central tendency called the mean, median and mode.
Step-by-step explanation:
Some facts/properties are:
1. There are three measures of the “center” of the data. They are the mode, median, and mean. Any of the values can be referred to as the “average.” The mode is the data value that occurs the most frequently in the data
2. And to find the measure of center:
The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.
3. The four measures of center are mean, median, mode, and midrange. ... Example: The median of 1, 3, 5, 5, 5, 7, and 29 is 5 (the number in the middle). Mode – The mode is the number that repeats most often in a data set. It's seldom used in statistics as a reliable measure of center.

The expansion of the given logarithm [tex]\mathbf{Log_3 (4x^2)}[/tex] is [tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]
What is the expansion of the logarithm?A Logarithm is an exponent to which a base must be raised in order to result in a given number. The expansion of the logarithm takes a predictable approach and set guidelines.
Using the set formula for solving logarithms;
[tex]\mathbf{log_a(x^n) = n \ log_a \ x}[/tex]
Let's assume that the correct equation given is:
[tex]\mathbf{=Log_3 (4x^2)}[/tex]

River Otters Drinks about 5 times as much as water as a bald eagle drink in a day
So we know that the bald eagle drinks 0.16 per day. (I am not sure liters, gallons, etc because it is not stated in the question.) Now, the question tells us that River Otters drink about 5 times MORE then the bald eagle. So first we need to multiply.
0.16 × 5 = 0.8
So river otters drink about 0.8 per day.
Now to find out how much a River Otter drinks in 3 days do:
0.8 × 3 = 2.4
Answer: River Otters drink 2.4 water in 3 days.

Find the measure of an exterior angle of the regular
polygon with 8 sides
Answer: 45°
Step-by-step explanation: The formula for finding the measure of each exterior angle of a regular polygon is simply 360/n where n represents the number of sides of the polygon.
Since our polygon has 8 sides, we plug 8 in
for n and we have 360/8, which is 45.
So our answer is 45°.
