The group wants to travel from its current location on the map to the South Pole, and then directly back to the base camp. How many miles will they have to travel? Explain your answer.
Using the Pythagorean Theorem, it is found that the group will have to travel 90 miles.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem:
First, the group travels 5 x 5 = 25 miles to the south pole.Then, the distance to the camp is the hypotenuse of a right triangle with sides of 25 miles and of 12 x 5 = 60 miles, hence:[tex]d^2 = 25^2 + 60^2[/tex]
[tex]d = \sqrt{25^2 + 60^2}[/tex]
d = 65.
The total distance is given by:
Td = 25 + 65 = 90 miles.

2. Convert the following functions.
(a) Convert the exponential function, 12x^4y^3z^6 , to its corresponding logarithmic function.
(b) Write the log form from Part A into the expanded log form. **expression must be fully expanded for
Answer:
Step-by-step explanation:
1) 3 = (1.2075)^n where n = number of months take log of both sides
log 3 = n log 1.2075

In a survey of 800 people, 42% said they shopped online last week. How many people said they shopped online last week?
336
explanation:
percent. part
_______ = _____
100. whole
42. ?
____ = ____
100. 800
cross multiply
800×42=33,600
then divide by 100
33,600/100=336
Answer:
336
Step-by-step explanation:
If 42% said they shopped online last week, that means the number of people who said they shopped online last week is 42% of 800. "Of" just means we should multiply, and since 42% = 42/100 (since % is just /100), we can use the following to find the answer (I used cross multiplication to simplify):
42 800 42 8
--- * = ---- * = 336

What is the slope of the line?
Answer:
[tex]-\frac{2}{3} x[/tex]
Step-by-step explanation:
Hey there!
To find slope, you take [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
In this case
y2: 6
y1: 4
x2: -3
x1: 0
Now we plug in this information
[tex]\frac{6-4}{-3-0} \\\\\frac{2}{-3} \\\\-\frac{2}{3}[/tex]
Since this is the slope, you have to add a "x"
So, the slope is [tex]-\frac{2}{3} x[/tex]

Then we have to solve the equation 3x + 11y = 100
Important: x and y are natural numbers
3x + 11y = 100 ⇔ 100 - 11y = 3x
If y=10 ⇒ 100 - 11×10 = −10 = 3x impossible because x ≥ 0
If y=9 ⇒ 100 - 11×9 = 1 = 3x impossible because x is a natural number
If y=8 ⇒ 100 - 11×8 = 12 = 3x ⇒ x = 12/3 = 4
Then (x,y) = (4,8) is a solution to the equation
If y=7 ⇒ 100 - 11×7 = 23 = 3x impossible because x is a natural number
If y=6 ⇒ 100 - 11×6 = 34 = 3x impossible because x is a natural number
If y=5 ⇒ 100 - 11×5 = 45 = 3x ⇒ x = 45/3 = 15
Then (x,y) = (15,5) is a solution to the equation
If y=4 ⇒ 100 - 11×4 = 56 = 3x impossible because x is a natural number
If y=3 ⇒ 100 - 11×3 = 67 = 3x impossible because x is a natural number
If y=2 ⇒ 100 - 11×2 = 78 = 3x ⇒ x = 78/3 = 26
Then (x,y) = (26,2) is a solution to the equation
If y=1 ⇒ 100 - 11×1 = 89 = 3x impossible because x is a natural number
If y=0 ⇒ 100 - 11×0 = 100 = 3x impossible because x is a natural number

The answer to the limitation of the Chi Square test (and all tests of hypothesis) about relationships between variables is none of the above.
What is the limitation of the chi square test?The Limitation of this type of test is in its sample size requirements, as there is a lot of difficulty of interpretation when samples are large.
Note that Chi Square test and all tests of hypothesis can tell us if relationships between variables are significant, random and also if it occurred by chance and as such they are no limitations here.

a tuba creates a 4th harmonic of frequency 116.5 hz what is the length of the pipe in the tuba
Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m
Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe
What is the frequency of an closed pipe?The frequency of a closed pipe f = nV/4L where
n = harmonic V = speed of sound and L = length of pipe in tubaLength of pipe in tubaMaking L subject of the formula, we have
L = nV/4f
Since the tuba creates the 4th harmonic with frequency 116.5 Hz.
n = 9 and f = 116.5 HzSubstituting the values of the variables into the equation, we have
L = nV/4f
L = 9 × 340 m/s/4 × 116.5 Hz
L = 3060 m/s ÷ 466 Hz
L = 6.57 m
So, the length of pipe in tuba is 6.57 m

(HELP PLS) Monica is building her dream home. It will have a total floor area of 2.150 sq. ft.
a. If Monica wants the living room to be 30% of the total area, what would the living room's area be?
b. The house Monica currently lives in has only 65% of the floor area of her dream home. What is the floor area of her current home?
The living room area of Monica's home is 0.645 ft².
The floor area of her current home is 1.3975 ft²
How to find percentage of an area?
The total floor area of Monica's dream home should be 2.150 ft².
Monica wants the living room to be 30% of the total area. Therefore, the living room area will be as follows:
living room area = 30 / 100 × 2.150 = 64.5 / 100 = 0.645 ft²
Her current house has only 65% of the floor area of her dream house. Therefore, the floor area of her current home is as follows:
Floor area of her current home = 65 / 100 × 2.150
Floor area of her current home = 139.75 / 100
Floor area of her current home = 1.3975 ft²

x^2+11x+28/x^2+5x+4 simplify expression
Answer:
(x + 7)/(x + 1)
Step-by-step explanation:
Simplify the following:
(x^2 + 11 x + 28)/(x^2 + 5 x + 4)
The factors of 4 that sum to 5 are 4 and 1. So, x^2 + 5 x + 4 = (x + 4) (x + 1):
(x^2 + 11 x + 28)/((x + 1) (x + 4))
The factors of 28 that sum to 11 are 7 and 4. So, x^2 + 11 x + 28 = (x + 7) (x + 4):
((x + 4) (x + 7))/((x + 4) (x + 1))
((x + 7) (x + 4))/((x + 4) (x + 1)) = (x + 4)/(x + 4)×(x + 7)/(x + 1) = (x + 7)/(x + 1):
Answer: (x + 7)/(x + 1)

Step-by-step explanation:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4
1. on both the top and the bottom you have to find a factor of the last number (in this case 28 and 4) that multiplys to be the number but adds to be the 2nd term (11x and 5x)
2. for the top the two terms would be (x+7) and (x+4). on thebottom half it would be (x+4) and (x+1)
** 7 times 4 equals 28, 7 plus 4 equals 11; 4 times 1 equals 4, 4 plus 1 equals
3. x+4 is common term on both the top side and the bottom half so you cross it out. this leaves us with our answer of: x+7 over x+1
