Answer:
1.342
Step-by-step explanation:
4^x+64^x=272
4^x+(4^3)^x=272
4^3x+4^x=272
(4^x)^3+4^x=272
(4^x)^3+4^x-272=0
u^3+u-272=0 ==> substitute 4^x with u
Now, use synthetic division to find roots:
\(\sqrt[3]{272}\)31 | 1 0 1 -272
\(\sqrt[3]{272}\)1 \(\sqrt[3]{272^2}\) 272
1 \(\sqrt[3]{272}\)1 \(\sqrt[3]{272^2}\) 0
4^x=\(\sqrt[3]{272}\)
log 4 (4^x)=log 4 (\(\sqrt[3]{272}\))=1.342

Let P(x) = -50x+20,000x-1,5000,000 represent the profit function for manufacturing a particular model of recreational

number of RVs that need to be sold each month for the company to make a profit.

O 0
O 100
Among the given answer choices, the correct option that represents this range is "0 100 200 none of the answer choices".
To determine the range of the number of RVs that need to be sold each month for the company to make a profit, we need to consider the profit function and find the values of x that result in a positive profit.
The profit function is given by P(x) = -50x + 20,000x - 1,500,000.
To make a profit, the value of P(x) must be greater than zero (P(x) > 0). We can set up the inequality:
-50x + 20,000x - 1,500,000 > 0.
Combining like terms, we have:
19,950x - 1,500,000 > 0.
Now, let's solve this inequality for x:
19,950x > 1,500,000.
Dividing both sides by 19,950, we get:
x > 1,500,000 / 19,950.
Simplifying the right side, we have:
x > 75.
The range of the number of RVs that need to be sold each month for the company to make a profit is x > 75.
Among the given answer choices, the correct option that represents this range is "0 100 200 none of the answer choices".

For each pair of functions f and g below, find f(g(x)) and g (f(x)).
Then, determine whether fand g are inverses of each other.
Simplify your answers as much as possible.
(Assume that your expressions are defined for all x in the domain of the composition.
You do not have to indicate the domain.)
f(x) = x+4
g (x) = x+4
The Function f(g(x)) = g(f(x)) = x + 8.
The functions are: f(x) = x + 4 and g(x) = x + 4. We can find f(g(x)) by substituting g(x) in place of x in f(x).
f(g(x)) = f(x + 4) = (x + 4) + 4 = x + 8
Similarly, we can find g(f(x)) by substituting f(x) in place of x in g(x).g(f(x)) = g(x + 4) = (x + 4) + 4 = x + 8
Thus, we can see that f(g(x)) and g(f(x)) are equal to each other,

Answer:
D. x+2y=12
Step-by-step explanation:
From the graph we know that the y-intercept is 6. (0,6) and the x-intercept is 12. (12,0)
The graph is going down so the slope is negative, from (0,6) count down to (0,0) and count right 12 unit to reach the x-intercept(12,0) the slope is -6/12 or -1/2.
the equation of the line is y=-1/2+6 or x+2y=12

Answer:
The probability that there will be

Step-by-step explanation:
This is a Poisson Distribution question.
The formula is given as:
For X = x ,

The monthly worldwide average number of air- plane crashes of commercial airlines is 3.5. What is the probability that there will be
(a) at least 2 such accidents in the next month?
= λ^x × e^-λ/x!
λ = 3.5
x = at least 2 such accidents
x ≥ 2
= 1 - [P(x = 0) + P(x = 1)]
= 1 - [(3.5^0 × e^-3.5/0!)+ (3.5^1 × e^-3.5/1!)]
= 1 - [ 1 × 0.0301973834 + 3.5 × 0.0301973834]
1 - [ 0.0301973834+ 0.105690842]

(b) at most 1 accident in the next month?
= λ^x × e^-λ/x!
λ = 3.5
x = at most 1 such accidents
x ≤ 1
= [P(x = 0) + P(x = 1)]
= [(3.5^0 × e^-3.5/0!)+ (3.5^1 × e^-3.5/1!)]
= [ (1 × 0.0301973834) + (3.5 × 0.0301973834)]

For what value of Θ is cotΘ undefined?
0°
180°
270°
The value of such that = k * 180, where k is an integer, is the value at which cotangent is undefinable.
Cotangent, or cot, is one of the six standard trigonometric functions. Cotangent of an angle is defined as the ratio of the adjacent side to the opposite side of a right-angled triangle.
The value of cotangent is undefined when the denominator is zero. This implies that cotangent is undefined at angles where the value of sine is zero.
Since the sine function is periodic and has a period of 360 degrees, the values of sine repeat themselves after every 360 degrees.
For this reason, cotangent is undefined at angles such that θ = k * 180, where k is an integer.
That is, cotangent is undefined at 0°, 180°, 360°, and so on. It is also important to note that cotangent is a periodic function, and its values repeat every 180 degrees.
Therefore, cotangent is undefined at 0° + k * 180°, where k is an integer.
To summarize, the value of Θ at which cotangent is undefined is such that θ = k * 180, where k is an integer.

what is inequalities
Inequalities are used in various branches of mathematics, as well as in real-world applications such as economics, physics, and social sciences, to describe relationships, make comparisons, and analyze data.
Inequalities are mathematical statements that describe a relationship between two values or expressions, indicating that one is greater than, less than, or not equal to the other. Inequalities are used to compare quantities and express their relative sizes or order.
The most common symbols used in inequalities are:
">" (greater than): indicates that the value on the left side is larger than the value on the right side.
"<" (less than): indicates that the value on the left side is smaller than the value on the right side.
"≥" (greater than or equal to): indicates that the value on the left side is greater than or equal to the value on the right side.
"≤" (less than or equal to): indicates that the value on the left side is less than or equal to the value on the right side.
"≠" (not equal to): indicates that the values on both sides are not equal.
Inequalities can be represented using variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Solutions to inequalities are often expressed as intervals or sets of values that satisfy the given inequality.

During halftime of a football game, a sling shot launches T-shirts at the crowd A T-shirt is launched from a height of 6 feet with an initial upward velocity of 72 feet per second Use the
equation h(t) = -16 +72t+6, where t is time in seconds and h(t) is height. How long will it take the T-shirt to reach its maximum height? What is the maximum height?
Answer:
Hope this helps ;)
Step-by-step explanation:
To find the time it takes the T-shirt to reach its maximum height, we need to find the value of t when the velocity of the T-shirt is zero, because at this point the T-shirt has reached its maximum height and starts falling back down. We can find the velocity of the T-shirt by taking the derivative of the height equation with respect to time:
v(t) = h'(t) = 72
The velocity of the T-shirt is a constant 72 feet per second, so it will never reach a velocity of zero and will never reach its maximum height. The T-shirt will keep going up indefinitely.
If the problem had specified that the T-shirt was launched with an initial upward velocity of -72 feet per second (meaning it was launched downward), then we could have found the time it takes the T-shirt to reach its maximum height by setting v(t) = 0 and solving for t. In this case, we would find that t = 1, so it would take the T-shirt 1 second to reach its maximum height. The maximum height would be h(1) = -16 + 72(1) + 6 = 62 feet.
Find the distance between the points A(-4, -3) and B(-8, 7). Round your answers to the nearest tenth.
Answer:
distance = 10.8
Step-by-step explanation:
the distance between 2 points is the Hypotenuse of the right angled triangle of the x and y coordinate differences.
so, Pythagoras is used.
c² = a² + b²
c = the Hypotenuse (the side of the triangle being opposite to the 90 degree angle).
x- difference : -4 - -8 = +4
y- difference : -3 - 7 = -10
c² = +4² + (-10)² = 16 + 100 = 116
c = sqrt(116) = 10.8
