Question 5 of 10
The graph shows the function f(x) = 2^x.
What is the value of x when f(x) = 4?
Answer:
A. 2
Step-by-step explanation:
Our y-axis is equivalent to f(x), so we can use it to find the value of x when f(x) = 4. If we look at the graph, we can find that an f(x) value of 4 (or, a y-value of 4) has an x-value of 2.
We could also figure this out by making f(x) equal to 4 in the equation:
[tex]4=2^{x}[/tex]
2 times itself how many times is equal to 4? Well, 2 times 2 is equal to 4, so 2 times itself two times is equal to 4. x is equal to 2:
[tex]4=2^{2}[/tex]
Either way works. If you have any more questions, let me know! :)
A hemispherical bowl of internal diameter 12 cm, full of water, is emptied into a cylindrical can 8 cm in diameter. How deep is the water in the can?
Step-by-step explanation:
The volume [tex]V_s[/tex] of a sphere of radius R is is given by
[tex]V_s = \frac{4\pi}{3}R^3[/tex]
so a hemisphere will only have half the volume of a sphere so we can write its volume [tex]V_h[/tex] as
[tex]V_h = \frac{1}{2}V_s = \frac{2\pi}{3}R^3[/tex]
Since the diameter D is twice the radius R, we can rewrite [tex]V_h[/tex] in terms of D as
[tex]V_h = \frac{2\pi}{3}\left(\frac{1}{2}D\right)^3 = \frac{\pi}{12}D^3[/tex]
[tex]\:\:\:\:\:\:\:=\frac{\pi}{12}(12\:\text{cm})^3 = 452.4\:\text{cm}^3[/tex]
Now represents the amount of water inside the hemisphere, which will be then transferred to a cylinder 8 cm in diameter. The volume of this cylindrical can [tex]V_c[/tex] must equal the volume of the hemisphere:
[tex]V_h = V_c = \pi R^2h = \pi\left(\frac{1}{2}D\right)^2h[/tex]
[tex]\:\:\:\:\:\:\:=\frac{\pi}{4}D^2h[/tex]
where h is the height (or depth) of the can. Solving for h, we get
[tex]h = \dfrac{4V_h}{\pi D^2} = \dfrac{4(452.4\:\text{cm}^3)}{\pi(8\:\text{cm})^2}[/tex]
[tex]\:\:\:\:\:= 9\:\text{cm}[/tex]

Hello, I want to ask. . anyone knows the answer.
Answer:
1
Step-by-step explanation:
i think what they want us to do here is round to the nearest tenth. however, as we all know, any number lower than five you must round down and convert to zeros. so, since the prescription called for 1.04 tablets per day, we can round down and get just 1.
so, 1 is your answer.
Answer: I believe the answer would be C, or 1
Step-by-step explanation: If he is supposed to take 1.04 tablets per day, the closest to that would be one tablet, because you can't really cut of 4% of a pill.

Find the equation of this line plz help
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{4-0}[/tex] = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex]
The line crosses the y- axis at (0, 1 ) ⇒ c = 1
y = - [tex]\frac{1}{2}[/tex] x + 1 ← equation of line
The function f(x) = −(x + 5)(x + 1) is shown. On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 3, 4), and goes through (negative 1, 0). What is the range of the function? all real numbers less than or equal to 4 all real numbers less than or equal to −3 all real numbers greater than or equal to 4 all real numbers greater than or equal to −3 Mark this and return
Answer:
All real numbers less than or equal to 4.
f(x) ≤ 4
Interval notation: (-∞, 4]
Step-by-step explanation:
Given the quadratic function, f(x) = -(x + 5)(x + 1), where the vertex occurs at point, (-3, 4):
Since the graph of the parabola opens down, then it means that the vertex is its maximum point. In reference to the vertical points on the graph (i.e., the range values), then the vertex sets the maximum range value of k = 4. This implies that the maximum possible range value is from negative infinity to positive 4.
Therefore, the range of the function is: all real numbers less than to or equal to 4.
f(x) ≤ 4

A company estimates that it can sell 3,000 units each month of its product if it prices each unit at $80. However, its monthly number of sales will increase by 10 units for each $0.10 decrease in price. The company has fixed costs of $250. The cost to make each unit is $4.20. Find the level of production that maximizes the company's profit.
The Should Produce _________
Units at a price of $__________
Which will yield a profit of $_______
9514 1404 393
Answer:
5290 units$57.10 per unit$279,591 profitStep-by-step explanation:
For price p, the quantity q of units sold is said to be ...
q = 3000 +10(80-p)/0.10 . . . . for price in dollars
Then the revenue will be ...
r(p) = p·q = p(3000 +100(80-p)) = 100p(110 -p)
The cost is said to be ...
c(q) = 250 +4.20q
c(p) = 250 +4.20(100(110 -p)) = 250 +420(110 -p)
Then the profit function is ...
P(p) = r(p) -c(p)
P(p) = 100p(110 -p) -(250 +420(110 -p)) = (110 -p)(100p -420) -250
__
Ignoring the vertical offset of -250, the quadratic has zeros at 110 and 4.2. So, its line of symmetry (and vertex) will be found at ...
p = (110 +4.2)/2 = 57.1 . . . . dollars per unit
The quantity that should be produced at that price is ...
q(57.1) = 100(110 -57.1) = 5290 . . . . units produced
The profit at that price is ...
P(57.1) = (110 -57.1)(100·57.1 -420) -250 = 52.9(5290) -250
= $279,591 . . . . best profit
_____
Additional comment
After you have seen a few of these, you can write down the revenue function based on the rate of change of units sold.
If p is the price of a unit, then 80-p is the number of dollars of decrease in price for a price of p. Then (80 -p)/0.10 is the number of 10¢ decreases in price. The increase in units sold is 10 times this, or 10(80 -p)/0.10 = 100(80 -p). When that is added to 3000 units sold, the total is ...
3000 +100(80 -p) = 3000 +8000 -100p
= 11000 -100p = 100(110 -p) . . . . . quantity sold at price p
Revenue is the product of price times the number of units sold at that price.
Profit is the difference between revenue and cost.

The length of a rectangle is 5 inches more that the width. The perimeter is 46 inches. Find the length and the width.
Answer:
1. Use variables to represent length and width.
width = w
length = w + 5
2. Set up an equation for the perimeter of the rectangle.
perimeter = 2L + 2W
2(w + 5) + 2(w) = 46
2w + 10 + 2w = 46
4w + 10 = 46
4w = 36
w = 9
3. Find the length and width of the rectangle.
width = w = 9 inches
length = w + 5 = 14 inches
Answer:
Width is 9 inches
Length is 14 inches
Step-by-step explanation:
width = w
length = w + 5
perimeter = 2L + 2W
2(w + 5) + 2(w) = 46
2w + 10 + 2w = 46
4w + 10 = 46
4w = 36
w = 9
Width = w = 9 inches
Length = w + 5 = 14 inches
Therefore the width is equal to 9 inches and the length is 14 inches.
