if f(x) = x^1/2– x and g(x) = 2x^3 –x^1/2-x
find f(x) – g(x).
f(x) - g(x) = [tex]-2x^{3}+2x^{1/2}[/tex]
Step-by-step explanation:
Given :
f(x) = [tex]x^{1/2} -x[/tex]g(x) = [tex]2x^{3} -x^{1/2} -x[/tex]f(x) - g(x) = ([tex]x^{1/2} -x[/tex]) - ( [tex]2x^{3} -x^{1/2} -x[/tex])
⇒ ([tex]x^{1/2} -x[/tex][tex]-2x^{3}+x^{1/2} +x[/tex])
⇒ [tex]-2x^{3}+2x^{1/2}[/tex]
f(x) - g(x) = [tex]-2x^{3}+2x^{1/2}[/tex]

the number. Find the nume.
Eight times a number plus 3 times
the number is the same as 9 more
than 12 times the number. Find the
number.
Answer: 8x+3x=12x+9
The number is -9.
Step-by-step explanation: Combine like terms.
11x=12x+9
Subtract 12x from the other side. 11x-12x= -1x
-1x+9
Divide by -1 to isolate x.
-1/-1 cancels out.
9/-1= -9
x=-9
Plug in -9 to check your answer if you want to double check.

Answer:
not 100% sure
Step-by-step explanation:
40÷3=13.3 minutes
Answer:
Step-by-step explanation:
if you want the ratio 40 seconds to 3 minutes
3 minutes=60×3=180 seconds
40 seconds to 180 seconds=40/140=2/9

linear, exponential, or neither?
Answer:
A) Linear
Step-by-step explanation:
For a linear relation, there will be a constant rate of change
For an exponential relationship, there will be a multiplicative rate of change.
For x-values, there is a constant difference of
[tex]d = 4 - - 3 = 11 - 4 = 18 - 11 = 7[/tex]
For the y-values, there is a constant difference of
[tex]b = 1 - - 3 = 5 - 1 = 9 - 5 = 4[/tex]
The rate of change of the function represented by the table is
[tex]m = \frac{change \: in \: y}{change \: in \: x} = \frac{4}{7} [/tex]
The equation can be derived as:
[tex]y + 3 = \frac{4}{7} (x + 3)[/tex]
This is a linear relationship
at current prices, roberta can drive her car 8.2 miles per dollar of gasoline that she buys. Roberta and three of her friends decide to go on a road trip to a neighboring university that is 105 miles away and agree to split the cost evenly . to the nearest cent, how much money will each have to contribute to get to the university and back?
Answer:
I think it's $12.80 but I might be wrong.
Each person will have to contribute $6.40.
Explanation:To find out how much money each person will have to contribute to get to the university and back, we can first find the total cost of the trip. The distance to the university and back is 2 times the distance to the university, which is 105 miles. So the total distance is 2 * 105 = 210 miles. Roberta's car can travel 8.2 miles per dollar of gasoline, so the total cost of the trip is 210 / 8.2 = 25.61 dollars. Since Roberta and three friends are splitting the cost evenly, each person will have to contribute 25.61 / 4 = 6.4025 dollars. Rounding to the nearest cent, each person will have to contribute $6.40.
coach currans team has won 5 times and lost 2 times.He hopes that his team can keep this same ratio of wins to losses.If the team has 10 losses,how many wins would they need to keep the record
Answer:
The answer is that the team has to have 25 wins.
Step-by-step explanation:
since the ratio is 2 losses to 5 wins, if you divide 10 by 2, you get 5. Multiply 5 by 5, since it is the other side of the ration, and you'll get 25 wins.
25:10 = 5:2

Alex swims in a 400-m freestyle competition at an average speed of 1 1/3 m/s. If he increases his average speed to 1.6 m/s, how much less time will he take?
50 seconds
Recall the equation
d=rt
Distance = rates times time.
We have a single distance, 400m
We have two different rates 1 1/3 m/s and 1.6 m/s
Let's calculate the time for each rate
t = d/r
t = 400/(1 1/3) = 300 seconds
t = 400/1.6 = 250 seconds
By increasing his average speed, Alex will reduce his time by
300-250 = 50 seconds.
In dealing with surface area what is net?
Answer:
Step-by-step explanation:
A net is a drawing that shows the edges and faces of a solid in two dimensions. You can think of a net as what you would get if you “unfolded” a solid. ... The net is made of three congruent rectangles and two congruent equilateral triangles. The surface area is the sum of the areas of the five shapes.

A certain shade of paint is made by mixing 5 parts of blue paint with 2 parts of white paint. To get the correct shade, how many quarts of white paint should be mixed with 8.5 quarts of blue paint?
Answer:
6.8 quarts of white paint
Step-by-step explanation:
If you make 5 parts equal to 0.5 you will have 17 parts blue paint. 17 divided by 5 (to get how many parts we are using) is 3.4. One part blue paint is 3.4 quarts. Times that by two to get how many parts of white paint. We need 6.8 quarts of white paint.
Use the function below to find F(2).
F(t) = 2•1/2^3t
Answer:
[tex]F(2)= \frac{1}{32} [/tex]
Step-by-step explanation:
The given function is
[tex]F(t) = 2 \cdot \: \frac{1}{{2}^{3t} } [/tex]
To find F(2), we substitute t=2 into the function.
This means that wherever we see t, we put 2
[tex]F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} } [/tex]
We multiply the exponent in the denominator to get:
[tex]F(2) = 2 \cdot \: \frac{1}{{2}^{6} } [/tex]
We evaluate to get:
[tex]F(2) = 2 \cdot \: \frac{1}{64} [/tex]
We now cancel the common factors to get:
[tex]F(2) = \frac{1}{32} [/tex]
Find the product of 4/5 and 5/12 put in simplest form
Hello!
The answer is 20/60 simplest form is 1/3
To get 20/60 you must multiply the Numerator by Numerator (4*5) and Denominator by Denominator (5*12). Your answer will be 20/60.
To get 1/3 you must simplify a number that can go into 20 and 60 (which is 10). Divide 20/10 and 60/10 and get 2/6. Simplify 2/6 by 2 and get 1/3.

3. Triangle ABC has angle measures as shown.
(a) What is the value of x? Show your work.
The value of x is 13°.
Solution:
In triangle, sum of all the interior angles = 180°
m∠A + m∠B + m∠C = 180°
(3x)° + (4x – 1)° + 90° = 180°
3x° + 4x° – 1° + 90° = 180°
7x° + 89° = 180°
Subtract 89° from both sides of the equation, we get
7x° = 91°
Divide by 7 from both sides of the equation, we get
x° = 13°
The value of x is 13°.

At which points does the graph of y=X(squared)+3x-18 intersect the x axis??
Step-by-step explanation:
Let A be the point at which the graph y=x²+3x-18
intersect the x-axis
As the graph intersects x-axis it's coordinate will be (x,0)
putting the value of y =0
x²+3x-18=0
x²+6x-3x-18=0
x(x+6)-3(x+6)=0
(x+6)(x-3)=0
x=-6, or,x=3
The point A maybe (-6,0) or (3,0)
y = x² + 4x + 8
Sketch the graph of each function be sure to show your table of values
Answer:
see attachment
Step-by-step explanation:
We want to sketch the graph of
[tex]y = {x}^{2} + 4x + 8[/tex]
We want to use tables so we choose some few points and plot.
When x=-6,
y=(-6)²+4(-6)+8=20
When x=-4,
y=(-4)²+4(-4)+8=8
When x=0,
y=(-2)²+4(-2)+8=4
When x=0,
y=(0)²+4(0)+8=8
When x=2,
y=(2)²+4(2)+8=20
The table and graph are shown in attachment.

Find two consecutive whole numbers that √92 lies between.
Answer:
9 and 10
Step-by-step explanation:
Consider perfect squares on either side of 92, that is
81 < 92 < 100, thus
[tex]\sqrt{81}[/tex] < [tex]\sqrt{92}[/tex] < [tex]\sqrt{100}[/tex], that is
9 < [tex]\sqrt{92}[/tex] < 10
Final answer:
To find two consecutive whole numbers that the square root of 92 lies between, we calculate the square root of 92 to determine its approximate value, which falls between 9 and 10.
Explanation:
To find two consecutive whole numbers that √92 lies between, we need to calculate √92 to determine its approximate value. Since 92 is between 81 (9²) and 100 (10²), the square root of 92 lies between 9 and 10. Therefore, the consecutive whole numbers are 9 and 10.
Frank has 27 liters of water. He pours equal amounts for 9 softball players. How much water will each player get?
A 36 liters
B. 18 liters
C. 4 liters
D. 3 liters
WIll MARK BRAINLIST PLZ!!
Answer:
d. 3 liters
Step-by-step explanation:
divide the amount of water by the amount of players to get the answer
27 ÷ 9 = 3
Answer:
D) 3 Liters
Step-by-step explanation:
We know that Frank has 27 liters of water, and he needs to divide it into equal amounts for 9 players. To find out how much water each of the 9 players will get, we can set up an equation like this:
(Amount of water) ÷ (Number of players) = (How much water each player gets)
Now we insert the numbers into this equation:
27 ÷ 9 = 3
So each player will get 3 liters of water
Ellen bought a new computer tablet for $460. She paid $100 at the time of purchase and will make monthly payments of $45 to finish paying for the tablet. She used the equation to determine the number of months (m) she needs to make payments. For how many months will she make payments?
Please help this is urgent!
Answer:
The answer is 8 months
Step-by-step explanation:
The new computer tablet is $460. She paid $100 at the time so I subtracted $100 from $460, which equals to $360. The monthly payments are $45 a month, so I divided $360 by $45, which equals 8. It takes 8 more months to finish the payment.
