Find the maximum value on (0, infinity) for f(x)=7x-2xlnx
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).
How to obtain the maximum value of a function?To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.
f(x) = max{0,x} then f(x)=0 if x<0 and f(x)=x if x≥0.
f(x)=7x-2xlnx
When x tends to -∞, f is the constant function zero, therefore limit n tends to infinity f(x) = 0.
When x tends to ∞, f(x)=x and x grows indefinitely. Thus limit n tends to infinity f(x) = infinity.
f is differentiable if x≠0. If x>0, f'(x)=1 (the derivative of f(x) = x and if x<0, f'(0)=0 (the derivative of the constant zero).
In x=0, the right-hand derivative is 1, but the left-hand derivative is 0, hence f'(0) does not exist,
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).

Does the infinite geometric series diverge or

Answer:
Diverge
Step-by-step explanation:
Infinite geometric series: In infinite geometeric series, if the common ratio 'r' is in between the interval -1 < r < 1, then it converges. If the common ratio 'r' is is not in the interval -1 < r < 1, then it diverges.5 + 20 + 80 + 320 + .....

r = 4 is not in the interval -1 < r < 1. So this infinite geometric series diverges.Patrick is designing a large stained glass window for the library. If the area of the window is 36 feet, how long is each side
4) In each of the following figures, find the value of the angles a,b,c,x,y,and z
Step-by-step explanation:
due to the principle of identical angles in parallel lines when intercepted by an inclined line,
y = 49°
the angles above an intersected line are the same as below that intersected line (just mirrored left-right).
and at the bottom, the angles an insecticide line has with one line must be the same as with another line that is parallel to the first line.
so, both indicated angles are the same as the original angle on the top : 49°

Find the area of the shaded region.
Use 3.14 for pi.
The area of the shaded region is 994.74 square in if the area of the circle is 1384.74 square in and the area of the triangle is 390 square in.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
As we know, the area of the circle is given by:
A = πr²
r = 21 in
A = 3.14(21)² = 1384.74 square in
Area of the triangle:
a = (39)(20)/2 = 390 square in
The area of the shaded region = 1384.74 - 390 = 994.74 square in
Thus, the area of the shaded region is 994.74 square in if the area of the circle is 1384.74 square in and the area of the triangle is 390 square in.

Answer:
(4, 0) and (-2, 0)(1, -9)(0, -8)Step-by-step explanation:
Finding the x-intercepts :
y-value of the x-intercept is 00 = (x - 4)(x + 2)x - 4 = 0 ⇒ x = 4x + 2 = 0 ⇒ x = -2The x-intercepts are : (4, 0) and (-2, 0)Finding the vertex :
Expanding the function ff(x) = (x - 4)(x + 2)f(x) = x² - 4x + 2x - 8f(x) = x² - 2x - 8Vertex = (h, k)h = -b/2a = -(-2)/2(1) = 1k = (1)² - 2(1) - 8k = 1 - 2 - 8 = -9The vertex is : (1, -9)Finding the y-intercept :
Substitute x = 0 in the functionf(0) = 0² - 2(0) - 8f(0) = -8The y-intercept is : (0, -8)In order to find x-intercept, the f(x) or y will be 0
=================
(x-4)(x + 2) = 0
(x-4) = 0, (x + 2) = 0
x = 4, x = -2
x intercepts: (4, 0) and (-2, 0)
2) What is the ordered pair of the vertex?In order to find vertex use the formula: x = -b/2a
y = (x-4)(x + 2)
y = x² -4x + 2x -8
y = x² - 2x -8
Now find x-coordinate of vertex:
x = -(-2)/2(1)
x = 2/2
x = 1
y coordinates: (1-4)(1 + 2) = -9
Ordered pair of vertex: (1, -9)
3) What is the y intercepts of the graph?In order to find y intercept, insert x = 0
y = (0-4)(0 + 2)
y = -8
y intercept: (0, -8)

Step-by-step explanation:
We need to follow the order of operations PEMDAS:
ParenthesesExponentsMultiplication and Division (from left to right)Addition and Subtraction (from left to right)Carry out the operation in the parentheses first:
3³ + 14.7 ÷ 7 - (1.2 × 4)
⇒ 3³ + 14.7 ÷ 7 - 4.8
Now the exponent:
⇒ 3³ + 14.7 ÷ 7 - 4.8
⇒ (3 × 3 × 3) + 14.7 ÷ 7 - 4.8
⇒ 27 + 14.7 ÷ 7 - 4.8
Now, the division (there is no multiplication):
⇒ 27 + 14.7 ÷ 7 - 4.8
⇒ 27 + 2.1 - 4.8
Finally, carry out the addition and subtraction (from left to right)
⇒ 27 + 2.1 - 4.8
⇒ 29.1 - 4.8
⇒ 24.3
The coordinates of the point SS are (7,6)(7,6) and the coordinates of point TT are (-2,6).(−2,6). What is the distance, in units, between the point SS and point T?T?
Answer:
9 units
Step-by-step explanation:
In the points S and T, the y- co ordinate are unchanged. So, the line joining S and T are parallel to x -axis.
So, the distance will be the sum of obsolute value of the x- coordinates.
Distance = I 7I + I - 2I
= 7 + 2
= 9 units

The red kite has a maximum altitude 23.11 feet higher than the black kite.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
1 feet = 0.3048 meters, hence:
117.46 m = 117.46 m * 1 ft per 0.3048 meter = 385.37 feet
Difference in height = 385.37 feet - 362.26 feet = 23.11 feet

There is no definite working. The first container is what I call the base because everything is a little above the first container, X. They are basically asking you what is the total of the four jars bigger than X. In other words how many steps more to climb before the top floor while you are on the first step. So then you add the other numbers like 0.5 etc which will give you X +3. Hope it helps.

Answer:
(x,y) = (2,3) so C?
Step-by-step explanation:
=> y = x/2+2
=> y = x + 1
from that info, you can tell y = y, meaning x/2 + 2 = x+1
solving:
=> x/2 + 2 = x + 1
=> 1/2x +2 = x + 1
=> -x -x
=> - 1/2x + 2 = 1
=> -2 -2
=> -1/2x = -1
=> * 2/-1 * 2/-1
=> x = 2
solve using substitution now:
(let's plug it in to the easiest y = statement)
=> y = x+1
=> y = 2 +1
=> y = 3
(2,3) is your answer

The value of log b to the nearest hundredth is 1.23. The correct option is the second option - 1.23
Evaluating logarithmFrom the question, we are to determine the value of log b to the nearest hundredth
From the given information
[tex]log_{5}b = log_{9}48[/tex]
But,
[tex]log_{9}48 =1.76186[/tex]
∴ [tex]log_{5}b =1.76186[/tex]
By one of the laws of logarithm
∴ [tex]b =5^{1.76186}[/tex]
b = 17.0407
Then,
log b = log(17.0407)
= 1.2315
∴ log b ≅ 1.23

The radius of a circle with area A is approximately $\sqrt{\frac{A}{3}}$ . The area of a circular mouse pad is 48 square inches. Estimate its radius to the nearest tenth
The radius of the circular mouse pad is 3.91 inches if the area of a circular mouse pad is 48 square inches.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
The area of the circular mouse pad = 48 square inches
The area of the circle:
[tex]\rm A = \pi r^2[/tex]
[tex]\rm 48 = \pi (r)^2[/tex]
Take π = 3.14
r = 3.909 inches ≈ 3.91 inches
Thus, the radius of the circular mouse pad is 3.91 inches if the area of a circular mouse pad is 48 square inches.
