Answer:
x = 19683 or x = 0
Step-by-step explanation:
Solve for x:
2 x = 54 x^(2/3)
Hint: | Isolate the radical to the left hand side by reversing the equality.
2 x = 54 x^(2/3) is equivalent to 54 x^(2/3) = 2 x:
54 x^(2/3) = 2 x
Hint: | Eliminate the power on the left hand side.
Raise both sides to the power of three:
157464 x^2 = 8 x^3
Hint: | Move everything to the left hand side.
Subtract 8 x^3 from both sides:
157464 x^2 - 8 x^3 = 0
Hint: | Factor the left hand side.
Factor x^2 and constant terms from the left hand side:
-8 x^2 (x - 19683) = 0
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by -8:
x^2 (x - 19683) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 19683 = 0 or x^2 = 0
Hint: | Look at the first equation: Solve for x.
Add 19683 to both sides:
x = 19683 or x^2 = 0
Hint: | Look at the second equation: Eliminate the exponent.
Take the square root of both sides:
Answer: x = 19683 or x = 0

Step-by-step explanation:
Ms.Koehler is planting A treat to help save the environment. She decided to keep track of the height of the tree over the years. After the first year Ms. Koehler measured the tree to be 8 feet tall. She took note that this was an increase of 3 feet from the previous year. Assuming the tree will continue to grow at this rate I answer the following questions.
Write an equation representing the height of Ms. Koehler’s three overtime, where y represents the height of the tree and x is the number of years since being planted
9514 1404 393
Answer:
y = 3x +5
Step-by-step explanation:
We are told the height increase is 3 ft in 1 year. That is the slope of the linear function representing height.
We are told that in year 1 the height was 8 ft, and that it was 3 ft less in the previous year. That is, it was 5 ft high in year 0. So, the y-intercept of the function is 5.
The slope-intercept equation is ...
y = mx + b . . . . for slope m and y-intercept b
y = 3x + 5

Lena drove 355 miles using 17 gallons of gas. At this rate, how many gallons of gas would she need to drive 284 miles.
Answer:
13.6 gallons
Step-by-step explanation:
Miles Driven = Gallons Burnt * Miles Per Gallon
So if yo drive 20.88 miles on one gallon how many gallons does it take to drive 284 miles. This is 284/20.88 = 13.6 gallons
Whilst the numerical answer is correct the previous answer, it does not maintain the validity of the units - in which things are measured. You will see this is very important in science
What can we learn from this. As an intermediate step we have learnt that the car does 20.88 mpg, lets call it 21. So a car that has a sticker at the show room with an MPG of more than 21 will consume less gas and one that has a smaller mpg will consume more.
can someone like solve this?

Answer:
bus: 324 ft long
P-H: 1154 miles
Step-by-step explanation:
In each case, we can use the relation that the length of an arc (s) is found by ...
s = rθ
where r is the radius and θ is the angle in radians.
__
1. 2°20'50" = (2 + 20/60 + 50/3600)(π/180) radians ≈ 0.0409668 radians
Then the length of the bus is ...
(0.0409668)(1.5 mi)(5280 ft/mi) = 324 ft
__
2. The difference in latitude is ...
41°17'5" -24°45'30" = 16°31'35" ≈ 0.288440 radians
Then the mileage between latitude lines is ...
s = (4000 mi)(0.288440 radians) ≈ 1154 miles
__
Additional comment
Neither of these problems should be considered to be realistic. An actual bus will subtend a far smaller angle at the given distance. The distance between cities must take into account longitude as well as latitude (and the latitudes must be properly associated with the cities).
Solve for a: -8b+2a=6c
Answer:
a=3c+4b
Step-by-step explanation:
-8b + 2a = 6c
(-8b + 2a) + 8b = 6c + 8b
-8b + 2a + 8b = 6c + 8b
-8b + 8b + 2a = 6c + 8b
2a = 6c + 8b
2a/2 = 6c + 8b/2
a = (2x3)c + [tex]2^{3}[/tex] x b)/2
a = 3c + 4b

A letter from the word CONFIDENCE is chosen at random, then a card is drawn from a standard deck. What is the probability of getting a consonant, them a red card or ace.
Answer:
9/26
Step-by-step explanation:
Word : CONFIDENCE
Consonants in word : C, N, F, D, N, C = 6
Total alphabets = 10
Probability =required outcome /Total possible outcomes
Probability (consonants) = 6 /10 = 3/5
Number of red catds in deck = 26
Number of aces in a card deck = 4
Total number of cards = 52
P(red) or P(ace)
(4/52) + (26/52) = (4 + 26) / 52 = 30 / 52 = 15 / 26
P(getting a consonant, then a red card or ace)
(3 /5) * (15/26) = (3 * 15) / (26 *5) = 45/130 = 9/26

Step-by-step explanation:
-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False
Answer:
true
Step-by-step explanation:
If x = - 3 is a zero of the polynomial then f(- 3) = 0
f(x) = x³ + 7x² + 16x + 12
= (- 3)³ + 7(- 3)² + 16(- 3) + 12
= - 27 + 63 - 48 + 12
= 0
Since f(- 3) = 0 then x = - 3 is a zero of the polynomial
A goalie makes 12 saves in 4 games. What is the unit rate of saves per game?
Answer:
3 saves per day
Step-by-step explanation:
Since we are finding the number of saves per day, our first dividor will be the number of saves, then we divide by the other number. We have 12 saves in total, and four games, so we will have to divide.
12 divided by 4 is equal to 3.
The answer to the question must be 3.
Answer:
12 saves/ 4 games = 3 saves/ 1 game = 3 saves per game
Step-by-step explanation:
A ration is basically a division problem. Divide until you get a denominator of 1.
12/ 4 = 3/ 1
So, if he makes 12 saves in 4 games, then he makes 3 saves per game.

Answer:
slope:(-0.5) y-intercept:0 equation:(-0.5x)
Step-by-step explanation:
To find slope, you use the formula y2-y1/x2-x1
For example, I used the first 2 sets of coordinates used in the table
(-2,1)&(-1,0.5)
First Part: 0.5-1= -0.5
Second part: -1-(-2)=1
Third Part: -0.5/1=(-0.5)
Y-intercept: In order to find the y-intercept, x needs to be 0.
Y-intercept=0
Equation:
The form for the equation should be, mx+b
B=Y-intercept
M=Slope
X=variable
The slope is -0.5 and you add the x after -0.5
Since the y-intercept is 0, it doesn't have a value so putting 0 at the end would be unnecessary. Slope:-0.5x

If gas costs $4.55 per gallon how many whole gallons of gas could you buy with $12.00?
The amount of gallons of gas that can be bought with $12 is 2.64 gallons.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Cost of gas per gallon = $4.55
This can be written as,
1 gallon = 4.55
Multiply 12/4.55 on both sides.
12/4.55 gallons = 12/4.55 x 4.55
2.64 gallons = 12
This means,
2.64 gallons for $12.
Thus,
2.64 gallons can be bought for $12.

10th term = 34
Step-by-step explanation:
3n+4
3(1)+4=7
3(2)+4=10
3(3)+4=13
3(4)+4=16
7,10,13,16
10th term = 3(10)+4= 34
The first four terms of the sequence having nth term 3n+4, are 7, 10, 13, 16 and the 10th term is 34.
What is arithmetic sequence ?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.
Given that,
The nth term of a sequence is given by 3n+4,
To find the first 4 terms, substitute the values of n,
At n=1, the first term = 3(1) + 4 = 3 + 4 = 7
At n=2, the second term = 3(2)+4 = 6 + 4 = 10
At n=3, the third term = 3(3) + 4 = 9 + 4 = 13
At n=4, the fourth term = 3(4) + 4 = 12 + 4 = 16
For 10th term, substitute n=10.
At n=10, the tenth term = 3(10) + 4 = 30 + 4 = 34
The first four terms are 7, 10, 13, 16 and the 10th term is 34.
