Answer:
True!
An irrational number has an infinite number of decimal places.
If the decimal ever ended, then the number would be rational.
Step-by-step explanation:
Answer:
The two equations are similar because they both end up with the same common value. 0=0 The work you need to show that this is correct will be shown below.
Step-by-step explanation:
2(5m−4)−3(m−5)2=−3m2+40m−83
Add 3m^2 to both sides.
−3m2+40m−83+3m2=−3m2+40m−83+3m2
40m−83=40m−83
Subtract 40m from both sides.
40m−83−40m=40m−83−40m
−83=−83
−83+83=−83+83
0=0

Answer:
The answer is $ 59.84
Step-by-step explanation:
Ok, I know this is not one of the options, but hear me out:
To find the sales tax for that item, you need to multiply the dollar amount by the sales tax (in percent):
$55 * 8.8% = $4.84
So the sales tax is $4.84. However, the question asks "How much would you pay for that item?", not what the sales tax is. So I would solve this problem by adding the sales tax to the dollar amount of the item:
$55 + $4.84 = $ 59.84
If you are able to write or type your answer, I would type $ 59.84. If you can only select one of the given values, then I would suggest going with A: $ 4.84 just because its the only number that is actually relevant at all to the problem.
Answer:
(g+f)(x)=(2^x+x-3)^(1/2)
Step-by-step explanation:
Given
f(x)= 2^(x/2)
And
g(x)= √(x-3)
We have to find (g+f)(x)
In order to find (g+f)(x), both the functions are added and simplified.
So,
(g+f)(x)= √(x-3)+2^(x/2)
The power x/2 can be written as a product of x*(1/2)
(g+f)(x)= √(x-3)+(2)^(1/2*x)
We also know that square root dissolves into power ½
(g+f)(x)=(x-3)^(1/2)+(2)^(1/2*x)
We can see that power ½ is common in both functions so taking it out
(g+f)(x)=(x-3+2^x)^(1/2)
Arranging the terms
(g+f)(x)=(2^x+x-3)^(1/2) ..
Answer:
The standard equation of the parabola is:
Step-by-step explanation:
An x intercept of 2 means that the point (2, 0) is in the graph of the parabola.
We can also write the general expression for the parabola in vertex form, since we can use the information on the coordinates of the vertex: (4, 6) - recall that the axis of symmetry of the parabola goes through the parabola's vertex, so the x-value of the vertex must be x=4.
Now we can find the value of the parameter "a" by using the extra information about the point (2, 0) at which the parabola intercepts the x-axis:
Then the equation of the parabola becomes:
