when the area of a circle is increasing twice as fast as the radius, the radius is given by
Answer:
r = 1/π
Step-by-step explanation:
The area of a circle is given by ...
A = πr²
The rate of change of area is ...
A' = 2πr·r'
We want that rate of change to be twice as fast as the rate of change of radius:
2r' = 2πr·r'
1 = πr . . . . . . divide by 2r'
1/π = r
When the area is changing twice as fast as the radius, the radius is 1/π.
_____
Additional comment
The area and the radius have different units, so their rates of change must be compared numerically. The numerical value will depend on the units used. The radius for a circle whose area is measured in m² will be different than for one whose area is measured in ft².

write an equation in slope-intercept form of the line that passes through the points (-5,-3) and (1,9)
Answer:
y = 2x + 7
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 ) = (- 5, - 3 ) and (x₂, y₂ ) = (1, 9 )
m = [tex]\frac{9-(-3)}{1-(-5)}[/tex] = [tex]\frac{9+3}{1+5}[/tex] = [tex]\frac{12}{6}[/tex] = 2 , then
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 9 ) , then
9 = 2 + c ⇒ c = 9 - 2 = 7
y = 2x + 7 ← equation of line

Simplify (45)-(+14). Pls guys explain it to me
Answer:
Answer: 31
Step-by-step explanation:
[tex]{ \rm{45 - ( {}^{ + } 14)}} \\ \\ = { \rm{45 - 14}} \\ \\ = { \rm{31}}[/tex]
Answer:
31
Step-by-step explanation:
(45)-(+14)
This is asking us to take 45 [(45)] and subtract 14 [-(+14)]
That is 45 - 14 = 31
The expression "-(+14)" is a deliberate attempt to confuse. It says "subtract a positive 14." There was no need to add the "+" sign in the parentheses, since a positive value is always assumed. But it was added here to promote heartburn and the sale of TUMS. When I see something like "-(+10000)," I immediately change it to "-10000" and move on, adding one demerit to the author of the problem.

A machine prints 8 banners in 120 seconds. How many seconds does it take to print one banner?
Answer:
15 seconds
Step-by-step explanation:
Number of seconds taken to print 8 banners = 120 seconds
Number of seconds taken to print 1 banner will be x seconds
Banners Seconds
8 120
1 x
By cross multiplication, we get
=> 120*1/8 = x seconds
=> 120/8 = 15 seconds
It takes 15 seconds to print one banner.

Answer:
43/10 pounds = 4 3/10 pounds
Step-by-step explanation:
for this you want to subtract 6 7/10 minus 2 2/5. You first have to get a common denominator and find the numerator then subtract.

Answer:
a) 52.5 ft. b)40.1ft c)12.5ft d) 72.6
Step-by-step explanation:
a) The height of the lighthouse is 84ft, and the angle of elevation is 58 degrees.
tan58=84/x
find x by dividing 84 by tan58, and you get 52.5ft.
b) do the same thing, except 131 is in the base of the right triangle shape. That being said, do tan17=x/131.
multiply 131 by tan17, and you get x=40.1 feet.
c) This question wants you to find the length of the slide, (basically the hypotenuse).
given the angle to be 46, do sin46=9/x
since sin is opp/hyp
9/sin46= 12.5ft
d) Find the angle of elevation by using inverse tan given the base to be 5, and the height to be 16ft.
tan^-1=(16/5)=theta
x=72.6 hope this helps!
Answer:
Step-by-step explanation:
In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x) = log(x), to achieve the graph of g(x) = log(-2x-4) + 1.
Using translation concepts, it is found that the parent function was:
Reflected over the x-axis.Horizontally compressed by a factor of 2.Shifted right 4 units.Shifted up 1 unit.The parent function is:
[tex]f(x) = \log{x}[/tex]
The first transformation is:
[tex]\log{x} \rightarrow \log{-x}[/tex]
Which means that it was reflected over the x-axis.Then, [tex]\log{-x} \rightarrow \log{-2x}[/tex], which means that it was horizontally compressed by a factor of 2.
Then, [tex]\log{-2x} \rightarrow \log{-2x - 4}[/tex], which means that it was shifted right 4 units.
Finally, 1 was added to the function, which means that it was shifted up 1 unit.

What is the answer
Answer:
Step-by-step explanation:
Part A:
y=1.5x+4.25
Part B:
16.25=1.5x+4.25
Minus 4.25 from both sides
12=1.5x
Divide both sides by 1.5 and you will get x=8
What are the vertices of PQR?
Answer:
D
Step-by-step explanation:
i may be wrong. if i am, sorry. but a vertice is basically just a point.
The vertices of the given triangle PQR are P, Q and R. Therefore, the correct answer is option D.
A vertex (plural vertices) in geometry is the intersection of two straight lines. Three line segments come together to form a triangle. The ends of a triangle's three sides meet at three separate points in a plane to form the triangle, which has three sides with two endpoints each. The vertices of a triangle are the three distinct intersecting points or corners.
Vertices of the triangle are represented by letters.
In triangle PQR, vertices are P, Q and R.
Therefore, the correct answer is option D.

4/9 + 9/18. Please help me as soon as possible, it's due today.
Answer:
[tex]\frac{17}{18}[/tex]
Step-by-step explanation:
To solve 4/9 + 9/18 just find the common denominator which is 18.
to get 4/9 to get the denominator of 18 you multiply the denominator by 2:
9 x 2 = 18, what you do to the bottom you do to the top (Multiply the numerator by 2 also) so, 4 x 2 = 8.
Now, add the numerator and keep the denominator the same. 8 + 9 = 17.
8/18 + 9/18 = 17/18

. Find

m∠N.
Answer:
Step-by-step explanation:
All the angles in a triangle add up to 180°
So you need to add up all your angles and set them equal to 180°
angleM + angleN + angleO=180
(6x+1) + (3x-10) + (x+19)= 180
We don't actually need all these parentheses; this is all just addition and subtraction.
6x+1+3x-10+x+19 =180
Add all the x terms together. Add all the constants (plain numbers) together.
10x + 10 =180
Subtract 10 from both sides
10x =170
Divide by 10.
x = 17
But you need one more step because if you reread the question, you are being asked for the measure of angle N, which is 3x - 10
3*17 - 10 =
51 - 10 =
41
The measure of angle N is 41°
