Answer:
.9417 ft/min
Step-by-step explanation:
Sphere volume = 4/3 pi r^3
dv/dr = 4/3 pi * 3 r ^2 = 4 pi r^2
dv/dr * dr/dt = dv/dt = 4 pi r^2 dr/dt
2.5 = 4 pi (1.3/2)^2 dr/dt (Diameter is 1.3 , radius is 1.3/2)
dr/dt = .4709 ft/min
THIS answer is how fast the RADIUS is changing
the DIAMETER is changeing TWICE this:
2 x .4709 ft/min = .9417 ft / min = diameter/dt
Is 1000 a sequence in 50 65 80 95
Answer: yes
Step-by-step explanation:
it’s the 41st term
Two players, A and B, are playing an asymmetrical game. There are n points on the game board. Each turn player A targets a pair of points and player B says whether those two points are connected or unconnected. A can target each pair only once and the game ends when all pairs have been targeted. Player B wins iff a point is connected with all other points on the very last turn, while player A wins if any point is connected with all other points on any turn but the very last one OR if no point is connected to all other points after the last turn. For what values of n does either player have a winning strategy?
The values of n does either player have a winning strategy is; Player B has a winning strategy for all n ≥ 2.
How to predict winning probability?Let us use an example to solve this question. The game is played on the complete graph Kₙ (n ≥ 2), which consists of n vertices, each pair of vertices joined by an edge.
Now, Initially all edges are unpainted. At each turn, A chooses an edge, which B paints blue or red. Now, B will win if, after the last edge is painted, there is a vertex which is joined to all other vertices by blue edges. If that doesn't happen, then A wins.
The winning strategy of B is described by 3 rules which are;
Rule 1; Paint the last edge blue.Rule 2. Never paint an edge red if that would result in two red vertices being joined by an unpainted edge.Rule 3. Use red paint whenever permitted by Rules 1 and 2.Thus, if n >2, the first edge will always be painted red, the second will always be painted blue.
In conclusion, when we apply that same scenario to our question it is the same result and as such Player B has a winning strategy for all n ≥ 2.

Mrs. Purdue needs to pick three random students in her class to be representatives on the student council. Explain how Mrs. Purdue could use slips of paper to generate a random sample.
Answer:
See below
Step-by-step explanation:
She could have each student in the class write his or her name on a slip of paper and put it in a bowl. Then, she could shake the bowl and pull out any slip of paper with a student's name on it. After 3 times, the random sample would be over, and Mrs. Purdue would have her 3 representatives.

The diameter of a circle is 7 cm, What is it's area/circumference????!
HELP!!!!
Answer:
Below in bold.
Step-by-step explanation:
Circumference = π * diameter
= π * 7
= 20.99 cm to nearest hundredth.
Radius of the circle = 1/2 * diameter = 7/2
= 3.5cm.
Area = π r^2
= π * 3.5^2
= 38.48 cm^2 to nearest hundredth.

[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Question:-}}}}\diamond[/tex]
◈ The diameter of a circle is 7 cm. What is its area? How about its circumference?
[tex]\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}\diamond[/tex]
We're asked to find the circle's circumference, which can be found using the formula below:-
[tex]\textsf{Formula for Circumference of a Circle:- \boxed{\bold{C=\pi d}}}[/tex]
Where:-
[tex]\bold{C=Circumference}[/tex][tex]\pi[/tex] = pi [3.14][tex]\bold{d=diameter}[/tex]As per provided information (d=7cm), we can easily find the circumference by substituting 7 for d:-
↬ [tex]\sf{C=\pi (7)}[/tex]
On simplification,
↬ [tex]\sf{C=7*3.14}[/tex]
Remember, 3.14 is pi.
On further simplification,
↬ C=21.98 cm.
So we conclude that the circumference of the given circle is:-
C=21.98 cm.
Now, how about the area?
[tex]\textsf{Formula for Area of a Circle:-\boxed{\bold{A=\pi r^2}}}[/tex]
Where:-
A=arear=radius (it's squared, which means it's multiplied times itself)Notice that we only have the diameter and not the radius.
We can easily find the radius by dividing the diameter by 2:-
3.5
So the radius is 3.5.
Substitute the value of r into the formula, which results in:-
↬ [tex]\sf{A=\pi (3.5)^2}[/tex]
On simplification,
A=12.25πOn further simplification,
A=12.25•3.14 (3.14 is pi)
On further simplification,
A=38.465 cm²

Answer:
[tex]\frac{1}{3} x^3 - x^2 + 4x[/tex]
Step-by-step explanation:
All this takes is the use of the power rule, which, for integrals, says that
∫[tex]x^n[/tex] = [tex]\frac{1}{n+1}x^{n+1}[/tex].
With this in mind, we can integrate:
∫[tex]x^2 - 2x + 4[/tex]
= [tex]\frac{1}{3} x^3 - x^2 + 4x[/tex].
We can also check our answer by differentiating our answer:
[tex]\frac{d}{dx} (\frac{1}{3}x^3 - x^2 + 4x)\\\\ = x^2 - 2x + 4[/tex]
so we are correct!

a knife is four times the cost of a spoon. 12 spoons and 16 knives cost £105.64. work out the cost of 1 knife
Answer:
£5.56Step-by-step explanation:
let K be the cost of a knife
S Ben the cost of a spoon
The statement “a knife is four times the cost of a spoon”
means K = 4S
means S = (1÷4)K
the statement “12 spoons and 16 knives cost £105.64”
means 12S + 16K = 105.64
⇔ 12(1÷4)K + 16K = 105.64
⇔ 3K + 16K = 105.64
⇔ 19K = 105.64
⇔ K = 105,64÷19
= £5.56

Martha bought a 0.35-kilogram bottle of spice. spice. She uses 80 grams a week. Is one bottle of spice enough for 6 weeks? Explain.
Answer:
She has not got enough spice for 6 weeks.
Step-by-step explanation:
Remark
0.35 kg = 0.35 * 1000 grams / kg = 350 grams.
Since she will use 6 * 80 = 480 grams for 6 weeks, and since 350 is less than 480, she does not have enough spice for six weeks.
Ade think of a number.he double it and then subtract five.the results cannot less than 100 . find the range of value of x
Answer:
[tex]x > \frac{105}{2}[/tex]
Step-by-step explanation:
Let's say that the number is [tex]x[/tex].
He doubles the number and then subtracts five to get the number to be [tex]2x - 5[/tex]. If the result cannot be less than 100, then we can write the inequality [tex]2x - 5[/tex] > [tex]100[/tex]. Now, solving for x, we get [tex]x > \frac{105}{2}[/tex].
