Answer:
x = 2
Step-by-step explanation:
(x² logₓ27) log₉x = x + 4
Use change of base formula.
x² (log 27 / log x) (log x / log 9) = x + 4
Simplify.
x² (log 27 / log 9) = x + 4
x² (log 3³ / log 3²) = x + 4
x² (3 log 3 / (2 log 3)) = x + 4
x² (3 / 2) = x + 4
3x² = 2x + 8
3x² − 2x − 8 = 0
(x − 2) (3x + 4) = 0
x = 2 or -4/3
Since x > 0, x = 2.

Answer:
-4 ± 2*sqrt(3)
Step-by-step explanation:
Well I'm not quite sure as to what the x= equations are, but for the solution to this quadratic I just used the quadratic formula. This gave me -8 ± sqrt(48)/2, which can be simplified to -4 ± 2 * sqrt(3). Hope this helps :)
The scatterplot that represents the monthly values of stock ABC can be
approximated by a line with a positive slope. What type of correlation does
this represent?
O
A. Negative correlation
O
B. No correlation
O
c. Positive correlation
Answer: A. Negative correlation
Step-by-step explanation:
A P E X
The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.
What is correlation?The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.
Correlations show that there is a relationship between two variables, but one does not always cause the other to change.
A positive correlation indicates that as one variable increases, so does the other.
In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.
Thus, the correct option is C.

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours
Step-by-step explanation:
All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.
Part 1: Garden Snail
= [tex]\frac{2,800}{0.029}[/tex]
≈ 96,551.7
Part 2: North American X-15
= [tex]\frac{2,800}{4,520}[/tex]

Find the volume of the composite figure below:
5 in
8 in
6 in
10 in
Answer:
716in³
Step-by-step explanation:
The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.
For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about 235.62 cubic inches.
For the volume of the other prism, we simply have to do length times height times width, or 6·8·10. That is equal to 480 cubic inches, which is the volume of that prism.
To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.
235.62+480= 715.62in³, or about 716in³.
Hope this helps.

What is the range of f(x)=(3/4)x-4
Answer:
Range of the function f(x) is all real numbers greater that -4, i.e., (-4,∞).
Step-by-step explanation:
The given function is f(x) = (3/4)x - 4
The value of (3/4)^x is greater than zero for any value of x. (3/4)^x > 0
Subtract 4 from both the sides. (3/4)^x - 4 > 0 - 4
f(x) > -4
The value of f(x) is greater than -4 for any value of x.
Therefore, the range of the function f(x) is all real numbers greater that -4. (-4,∞).

Find the equation of the line that passes through (-4, 8) and has a slope of -3.
Answer:
y= -3x-4
Step-by-step explanation:
Since we already know the slope, we have to plug in values to find out the constant of the equation. We use the point given to figure it out. Y+8 and x=-4, therefore 8=-3(-4)+c ---> 8=12+c. C=-4
