the radius of a sphere is increasing at a rate of 4 mm/s. how fast is the volume increasing (in mm3/s) when the diameter is 80 mm? (round your answer to two decimal places.)
Increase in volume is 802424.77 cubic mm/s when the diameter is 80 mm.
Let the radius of the sphere be R.
So, the volume of the sphere is given by,
V = [tex]\frac{4}{3}\pi r^3[/tex]
Differentiating the above relation with respect to time 't' we get,
dV/dt = 4[tex]\pi r^2[/tex]. dr/dt
Given that, the change of radius (dr/dt) = 4 mm/s
When the diameter is 80 mm, then the radius = 80/2 = 40 mm
So the volume change when the diameter is 80 mm is given by,
dV/dt [tex]=4\pi\times40^2\times4\approx 802424.77[/tex] cubic mm/s
Hence the volume increase in 802424.77 cubic mm/s.

Step-by-step explanation:
Identify x-intercepts, the vertex, and axis of symmetry of the graph f(x)= 1/4x (x-1)(x+7)
x = 1 and x = -7 are the x - intercepts, the vertex is, (-3, -4), and axis of symmetry is x = -3.
What is, axis of symmetry, vertex and x - intercept?
A vertical line that splits the parabola into two equal half is the axis of symmetry. The equation x = - b/2a tells us where the line of symmetry lies. The parabola's vertex, which is a point (x, y), is where it crosses its axis of symmetry.
A line's x-intercept is the location at which the x-axis is crossed.
Consider, the given equation,
[tex]f(x) = \frac{1}{4}(x - 1)(x + 7)[/tex]
Let,
[tex]y = \frac{1}{4}(x - 1)(x + 7)[/tex] ..(1)
To find x - intercept, plug y = 0 in above equation,
[tex]\frac{1}{4}(x - 1)(x + 7) = 0\\ (x - 1)(x + 7) = 0\\(x - 1) = 0, (x + 7) = 0\\x = 1, x = -7[/tex]
Therefore, x = 1 and x = -7 are the x - intercepts.
Since, the x-coordinate of the vertex is at the midpoint of the x-intercepts.
So,
[tex]x = \frac{-7+1}{2} = \frac{-6}{2} = -3[/tex]
Plug x = -3 in equation (1)
[tex]y = \frac{1}{4}(-4)(4) = -4[/tex]
Therefore, the vertex is, (-3, -4).
The x - coordinate of the vertex is the axis of symmetry.
Therefore, axis of symmetry is x = -3.
Hence, x = 1 and x = -7 are the x - intercepts, the vertex is, (-3, -4), and axis of symmetry is x = -3.

Dividing the polynomial P(x) by x + 2 yields a quotient Q(x) and a remainder of 8. If Q(2) = 5, find P(-2) and p(2)
================================================
Explanation:
Part A) Find P(-2)
We'll divide P(x) over (x+2) to get a quotient Q(x) and remainder 8 like so
P(x)/(x+2) = quotient + remainder/(x+2)
P(x)/(x+2) = Q(x) + 8/(x+2)
When multiplying both sides by (x+2), it clears out the fractions and we're left with this
P(x) = (x+2)*Q(x) + 8
From here, plug in x = -2 and simplify
P(x) = (x+2)*Q(x) + 8
P(-2) = (-2+2)*Q(-2) + 8
P(-2) = (0)*Q(-2) + 8
P(-2) = 0 + 8
P(-2) = 8
Luckily we don't need the value of Q(-2) since it cancels out with the zero.
-----------------------------------
Part B) Find P(2)
This time we'll plug in x = 2 and we'll get...
P(x) = (x+2)*Q(x) + 8
P(2) = (2+2)*Q(2) + 8
P(2) = 4*Q(2) + 8
P(2) = 4*5 + 8
P(2) = 20+8
P(2) = 28

4) The "random walk theory of stock prices holds that price movements in disjoint time periods are independent of each other. Suppose that we record only whether the price is up or down each year, and that the probability that our portfolio rises in price in any one year is 0.65.
a) What is the probability that the portfolio goes up for 3 consecutive years?
b) What is the probability that the portfolio's value moves in the same direction (either up or down) for 3 consecutive years?
c) What is the probability that the portfolio's value goes up for at least 1 of 3 years?
Part (a)
Each year is independent of any other. This allows us to simply multiply the probability values for each increase. Recall that P(A and B) = P(A)*P(B) if and only if events A & B are independent.
(0.65)*(0.65)*(0.65) = (0.65)^3 = 0.274625
Answer: 0.274625=========================================
Part (b)
We calculated the probability of an increase for each of the 3 years back in part (a). Let's calculate we have a decrease 3 times in a row.
0.65 is the probability of increase for any given year, which makes 1-0.65 = 0.35 the probability of decrease for any given year.
Therefore (0.35)^3 = 0.042875 represents the probability of 3 decreases in a row.
Add this result to what we got in part (a)
0.274625+0.042875 = 0.3175
This is done because we could have 3 increases OR 3 decreases (pick one). Think of it like this P(A or B) = P(A) + P(B) where A & B are mutually exclusive events.
Answer: 0.3175=========================================
Part (c)
In the previous part we calculated 0.042875 as the probability of 3 decreases in a row.
1-0.042875 = 0.957125 is the probability of at least one increase. Note how the events "no increases" and "at least one increase" are complementary events. They are opposite. One or the other must happen, which allows us to subtract from 1.
You can think of it like this
P(no increases) + P(at least one increase) = 1
P(at least one increase) = 1 - P(no increases)
Answer: 0.957125Side note: none of the final answers have been rounded.

given: line 1 passes through (-3, -7) and (5,3)
Line 2 passes through (-4, -2) and is perpendicular to line 1
Answer:
Step-by-step explanation:
We start by developing an equation for Line 1, and then use that to find the equation for Line 2. We'll use the form of an equation for a straight line:
y = mx + b,
where m is the slope and b the y-intercept (the value of y when x=0).
Line 1
Determine the slope, m, by calculating the "Rise/Run" between the two points (-3,-7) and (5,3).
Line up the two points from left to right (based on x) and then calculate:
Rise: (3 - (-7)) = 10
Run: (5 -(-3) = 8
The slope, m, is Rise/Run or (10/8)
The equation becomes y = (5/4)x + b
We could calculate b, the y-intercept, by entering one of the two given points and solving for b, but the only thing we need from this line is it's slope, m. Slope is (5/4), which we'll use in the next step: Line 2.
[Note: Out of curiosity, here is the calculation for b: Use point (5,3) in y = (5/4)x + b and solve for b. 3 = (5/4)*5 + b. 3 = (25/4) + b b = -13/4. This means that Line 1 is y = (5/4)x -(13/4)]
Line 2
The slope of a line perpendicular to the first is the "negative inverse" of the first line. In this case, line 1's slope of (13/8) would become a slope of -(8/13) for line 2.
Line 2: y = -(8/13)x + b
We'll calculate b for this line by enetering the single point provided, (-4,-2), and solving for b:
y = -(8/13)x + b
-2 = -(8/13)*(-4) + b
-2 = (32/13) + b
-2 - (32/13) = b
b = -(26/13) - (32/13)
b = -(58/13)
The new line perpendicular to Line 1 and passing through (-4,-2) is:
y = -(8/13)x -(58/13)

Arun spends some of the money from his monthly salary on food, travelling and entertainment and the rest of the money he deposits in the bank. (i) The money he spends on food, travelling and entertainment is in the Ratio, food : travelling : entertainment = 4 : 2 : 3. If he spends on food $160 more than travelling calculate the amount he spends on entertainment.
(c) If he deposits 1/7 of his monthly salary , calculate his monthly salary
The amounts are given as follows, using proportions:
i) Amount spent on entertainment: $240.
c) Monthly salary: $840.
What is a proportion?A proportion is a fraction of an amount, and this fraction is combined with the unit rates in the context of a problem along with basic arithmetic operations such as multiplication or division to find the desired amounts.
The ratio of food : travelling : entertainment = 4 : 2 : 3 means that:
4/9 of the investment was in food.2/9 of the investment was in travelling.3/9 of the investment was in entertainment.The amount spent on food $160 more than travelling, the total amount is obtained as follows:
(4/9 - 2/9)x = 160
2/9x = 160
2x = 160 x 9
x = 80 x 9
x = 720.
Then the amount invested in entertainment was of:
3/9 x 720 = 1/3 x 720 = $240.
He invests 6/7 of his monthly salary, as 1/7 is deposited, hence:
6x/7 = 720
6x = 720 x 7
x = 120 x 7 (simplifying both sides of the equality by 6)
x = $840.

Graph the image of △IJK after the following sequence of transformations:
Translation 17 units left and 5 units up
Reflection across the line y=1
Please find attached the graph of the image of ΔIJK following a translation transformation of (-17, 5), and a reflection across the line y = 5
What is a transformation in geometry?A transformation is an operation that changes the location, size and shape of geometric figures.
The coordinates of the vertex of ΔIJK are; I(14, 8), J(8, 5), K(14, 2)
The translation transformation is 17 units left and 5 units up = T₍₋₁₇, ₅₎
The location of the vertices of the image of ΔIJK following the translation transformation are;
[tex]I(14,\, 8)\ \underset{\longrightarrow}{T_{(-17,\, 5)}}\ I'(-3,\, 13)[/tex]
[tex]J(8, 5)\ \underset{\longrightarrow}{T_{(-17,\, 5)}}\ j'(-9,\, 10)[/tex]
[tex]K(14, 2)\ \underset{\longrightarrow}{T_{(-17,\, 5)}}\ K'(-3,\, 7)[/tex]
The coordinates of a point following a reflection across the line y = 1 are as follows;
The coordinates of the vertices of the image I'J'K' relative to the line y = 1 are;
I'(-3, 13), Relative point I'(-3, 12)
J'(-9, 10) has a relative point at (-9, 9)
K'(-3, 7) has a relative point (-3, 6)
The coordinates of the vertices of the reflected image are therefore;
(x, y) [tex]\underset{\longrightarrow}{R_{y = 1}}[/tex] (x, -(y - 1))
Which gives;
I'(-3, 12) [tex]\underset{\longrightarrow}{R_{y = 1}}[/tex] I''(-3, -12 + 1) = I''(-3, -11)
J'(-9, 9) [tex]\underset{\longrightarrow}{R_{y = 1}}[/tex] I''(-9, -9 + 1) = I''(-9, -8)
k'(-3, 6) [tex]\underset{\longrightarrow}{R_{y = 1}}[/tex] k''(-3, -6 + 1) = k''(-3, -5)
