Answer:
g(f(x)) = √((x²+5)/(x²+4))
Step-by-step explanation:
[tex]g(f(x))=g(\dfrac{1}{x^2+4})=\sqrt{\dfrac{1}{x^2+4}+1}=\sqrt{\dfrac{1+x^2+4}{x^2+4}}\\\\\boxed{g(f(x))=\sqrt{\dfrac{x^2+5}{x^2+4}}}[/tex]
I prefer this compact form, but some may want the denominator rationalized. This means the expression becomes ...
[tex]g(f(x))=\sqrt{\dfrac{(x^2+5)(x^2+4)}{(x^2+4)^2}}\\\\\boxed{g(f(x))=\dfrac{\sqrt{x^4+9x^2+20}}{x^2+4}}[/tex]

Select the correct answer. The function g(x) = x2 is transformed to obtain function h: h(x) = g(x) − 5. Which statement describes how the graph of h is different from the graph of g? A. The graph of h is the graph of g horizontally shifted right 5 units. B. The graph of h is the graph of g horizontally shifted left 5 units. C. The graph of h is the graph of g vertically shifted up 5 units. D. The graph of h is the graph of g vertically shifted down 5 units.
Answer:
D. The graph of h is the graph of g vertically shifted down 5 units.
Step-by-step explanation:
I assume
g(x) = x²
h(x) = g(x) - 5 = x² - 5
If f(x)= 2|x|+3x, then the value of f(-1) is
Answer:
-1
Step-by-step explanation:
f(-1) = 2|-1| + 3(-1)
|-1| = 1
=> f(-1) = 2(1) - 3
=> f(-1) = 2 - 3
=> f(-1) = -1
The distance that John covers each day during his morning walks is given in the graph. Using my this information, predict the distance that John may cover on day 6
A: 5.2 miles
B: 4.2 miles
C: 3.2 miles
D: 2.2 miles
John may cover 2.2 miles on day 6.
The correct answer is option (D)
What is graph?"It is a pictorial representation of data in an organized manner. "
For given question,
The distance that John covers each day during his morning walks is given in the graph.
From the graph we can observe that the highest value on the graph is 4.
Also the data is symmetrical on the left side and on the right side of the highest value.
We need to predict the distance that John may cover on day 6.
It must be the same as it is at day = 0
At day = 0, the distance is 2.2 miles.
Therefore, John may cover 2.2 miles on day 6.
The correct answer is option (D)

A chemist is using 332 milliliters of solution of acid and water. If 13.7% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.
Answer:
45.5 milliliters
Step-by-step explanation:
We know that the chemist has 332 milliliters of the solution of acid and water, and 13.7% of that solution is acid.
We can then persume that the amount of acid in the solution is equal to 332ml × 13.7%.
This is equal to 45.484ml.
Then the question states to round the answer to the nearest tenth.
Rounding 45.484ml to the nearest tenth (.1) will equal to 45.5ml.
Therefore, there are 45.5ml of acid in the solution rounded to the nearest tenth.
evaluate f(x)=-2x²+4x-2 find f(-2)
Answer:
-2
Step-by-step explanation:
If f(x) = 2x² + 4x - 2
f(-2) = 2(-2)² + 4(-2) - 2
f(-2) = 2(4) + 4(-2) - 2
f(-2) = 8 - 8 - 2
f(-2) = -2
Answer:
It is -18
Step-by-step explanation:
[tex]f(x) = - 2 {x}^{2} + 4x - 2[/tex]
when x is -2, f(x) is f(-2):
[tex]f( - 2) = - 2 {( - 2)}^{2} + 4( - 2) - 2 \\ \\ f( - 2) = - 8 - 8 - 2 \\ \\ f( - 2) = - 18[/tex]

5(6)-(0)≠95(6)-(0)=30Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. The temperatures of eight different plastic spheres.
The level of measurement that is most appropriate for the temperatures of eight different plastic spheres is the interval scale.
An interval scale shows magnitude and order. It shows numerical difference between values on same scale which are distinguished and are equal.
One common property of the interval scale is that it has an arbitrary zero point which is perfectly exhibited by the temperature measurement. This implies that the scale of measurement has no zero point because zero on the Centigrade scale is 32 degrees on the Fahrenheit scale.
Therefore, temperature measurement of eight different spheres can be regarded as an interval scale.

We can use proportions to solve
12 5
----- = -----
18 x
Using cross products
12x = 18*5
12x = 90
Divide by 12
12x/12 = 90/12
x = 7 1/2
12/18 = 5/x
12x = 18 × 5
12x = 90
x = 90 ÷ 12
x = 7,5 => x = 7 1/2

Answer:
9
Step-by-step explanation:
The trinomial square have the following form:
(a - b)²
Expanding this, the result is:
a² -2ab +b²
So, let's put x in place of a and solve it:
x² -2•x•b + b²
Now, we know that initially -2•x•b was -6x in the given trinomial square, so let's find the value of b using an equation:
-2x•b = -6x divide both sides by -2x:
b = -3
So -3 complete our trinomial square, and it is:
(x -3)²
Expanding:
x² -6x +9

log 3x^3-log x^2= log 27 - log x
Answer:
First of all, this equation is defined on ]3,+∞[ because you need x+3>0 and x−3>0 at the same time or the log won't be defined.
The log function maps a sum into a product, hence log(x+3)+log(x−3)=27⇔log[(x+3)(x−3)]=log27.
You now apply the exponential function on both sides of the equation : log[(x+3)(x−3)]=log27⇔(x+3)(x−3)=27⇔x2−9=27⇔x2−36=30. This is a quadratic equation that has 2 real roots because Δ=−4⋅(−36)=144>0
You know apply the quadratic formula x=−b±√Δ2a with a=1 and b=0, hence the 2 solutions of this equation : x=±6
−6∉]3,+∞[ so we can't keep this one. The only solution is x=6.
