If the radius of a circle is 5 centimeters, how long is the arc subtended by an angle measuring 60°? A) 3 5 π cm B) 5 2 π cm C) 5 3 π cm D) 5 6 π cm
Answer:
The length of the arc is [tex]\frac{5\pi}{3}[/tex] centimeters.
Step-by-step explanation:
The length of an arc ([tex]\Delta s[/tex]) with a given central angle is determined by the following expression:
[tex]\Delta s = \frac{\theta}{360^{\circ}}\cdot 2\pi\cdot r[/tex]
Where:
[tex]r[/tex] - Radius, measured in centimeters.
[tex]\theta[/tex] - Central angle, measured in sexagesimal degrees.
Given that [tex]r = 5\,cm[/tex] and [tex]\theta = 60^{\circ}[/tex], then:
[tex]\Delta s = \frac{60^{\circ}}{360^{\circ}} \times 2\pi \times 5\,cm[/tex]
[tex]\Delta s = \frac{5\pi}{3}\,cm[/tex]
The length of the arc is [tex]\frac{5\pi}{3}[/tex] centimeters.

Solve for x: 3(x+1) = 2(x-1)
Answer:
-5
Step-by-step explanation:
First do whats in the parentheses
so it will look like this
3x+3=2x-2 now subract 2x from 3x you get x
x+3=-2
now minus 3 from -2 and you get -5
x= -5
Write out the steps that you would follow to solve the equation: 3(x-4) = 2x +5
Answer:
x = 17
Step-by-step explanation:
To solve this equation, we can illustrate the algebraic concepts being employed and solve for the variable.
3(x - 4) = 2x + 5 Distribute the 3 into the parentheses.
3x - 12 = 2x + 5 Subtract 2x from both sides of the equation to combine like terms.
x - 12 = 5 Add 12 to both sides of the equation.
x = 17
Answer:
[tex] \displaystyle \rm \longmapsto \:3(x - 4) = 2x + 5[/tex]
[tex] \displaystyle \rm \longmapsto \:3x - 12 = 2x + 5[/tex]
Subtract 2x from the both sides:[tex] \displaystyle \rm \longmapsto 3x - 2x - 12 = 2x - 2x + 5[/tex]
[tex]\displaystyle \rm \longmapsto x - 12 = 5[/tex]
Add 12 to the both sides:[tex]\displaystyle \rm \longmapsto x - 12 + 12 = 5 + 12[/tex]
[tex]\displaystyle \rm \longmapsto x = 15[/tex]
Simplify the rational expression(picture and choices attached)! 15 points and will give Brainliest. Due soon.
Answer:
The answer should be:
[tex]=\frac{8x^3-18x}{3x+2}[/tex]
The closest answer is A, so I'll go with that.
Step-by-step explanation:
So we have the rational expression:
[tex]\frac{4x^3-9x}{2x-7}\div\frac{3x^2+2x^2}{4x^2-14x}[/tex]
First, remove the division sign. To do so, turn the division into multiplication and flip the second term:
[tex]\frac{4x^3-9x}{2x-7}\cdot \frac{4x^2-14x}{3x^2+2x}[/tex]
Now, simplify. From the first term, in the numerator, factor out a x. On the second term, factor out a 2x in the numerator and a x in the denominator:
[tex]\frac{x(4x^2-9)}{2x-7}\cdot\frac{2x(2x-7)}{x(3x+2)}[/tex]
Multiply straight across:
[tex]\frac{x(4x^2-9)(2x)(2x-7)}{(2x-7)(x)(3x+2)}[/tex]
Cancel out the (2x-7):
[tex]\frac{x(4x^2-9)(2x)}{x(3x+2)}[/tex]
Cancel out the x:
[tex]\frac{(2x)(4x^2-9)}{(3x+2)}[/tex]
At this point, we can factor the (4x^2-9) term, but we won't be able to cancel it out. Thus, this is the simplest it can get.
To get the answer, expand the numerator:
[tex]=\frac{8x^3-18x}{3x+2}[/tex]
Thus, the answer is...
A?
Answer:
The right solution is option a : [tex]\frac{8x^2 - 18}{3x+2}[/tex]
Step-by-step explanation:
We have to simplify the following rational expression,
[tex]\frac{4x^3-9x}{2x-7}[/tex] ÷ [tex]\frac{3x^3+2x^2}{4x^2-14x}[/tex]
Take into account the rule (a / b) / (c / d) = ad / bc. This simplifies the expression a bit further --- (1)
[tex]\left(4x^3-9x\right)\left(4x^2-14x\right)[/tex] ÷ [tex]\left(2x-7\right)\left(3x^3+2x^2\right)[/tex]
Let's now factor each individual expression as demonstrated below. Afterwards we can substitute back into the expression above --- (2)
Goal - Factor : (4x³ - 9x)(4x² - 14x),
4x³ - 9x ⇒ x(4x² - 9)
4x² - 14x ⇒ 2x(2x - 7)
[tex]x\left(4x^2-9\right)\cdot \:2x\left(2x-7\right) = 2x^2\left(4x^2-9\right)\left(2x-7\right)[/tex]
That leaves us with the following expression,
[tex]2x^2\left(4x^2-9\right)\left(2x-7\right)[/tex] ÷ [tex]\left(2x-7\right)\left(3x^3+2x^2\right)[/tex]
As you can see the " 2x - 7 " cancel out, and the " x² " cancel as well, leaving us with a further simplified expression,
[tex]2\left(4x^2-9\right)[/tex] ÷ [tex]3x+2[/tex]
Which can also be rewritten as [tex]8x^2 - 18[/tex] ÷ [tex]3x + 2[/tex] = [tex]\frac{8x^2 - 18}{3x+2}[/tex], in other words the first option.

Earth rotates on an axis through its poles. The distance from the axis to a location on Earth at 40 degrees north latitude is about 3033.5 miles. Therefore a location on Earth at 40 degree north latitude is spinning on a circle of radius 3033.5 miles. Compute the linear speed on the surface of the Earth at 40 degrees north latitude.
Answer: v = 793.77 mph
Step-by-step explanation: Linear speed of a circular movement is calculated by using the formula:
v = ω.r
where
ω is angular velocity
r is radius of the path
Angular velocity is the rate of change of the angular position of an object with respect of time, i.e., is how fast an object changes its angular position with time:
[tex]\omega = \frac{d \theta}{dt}[/tex]
[tex]\omega = \frac{2\pi}{time}[/tex]
The Earth takes 24 hours to complete a rotation, then angular velocity:
[tex]\omega = \frac{2\pi}{24}[/tex]
[tex]\omega =[/tex] 0.262 rad/h
At a location 40° north, radius is 3033.5 miles, so:
v = 0.262*3033.5
v = 793.77
At latitude of 40°north, linear speed is 793.77mph.

PLEASE HELP BRAINLIEST FOR WHOEVER ANSWERS CORRECTLYYYYYYYYYYYYYYY the perimeter P of a square is four times the length of one side s, which can be expressed as P = 4s. is (13,51) a solution of this equation? if not, find a solution that uses one or the other of the given values
Answer:
No, but (13,52) is
Step-by-step explanation:
To find this you need to understand what (13,51) means.
13 = x coordinate
51 = y coordinate
If you plug 13 into the equation given (P = 4s) you get 52. Therefore, (13,51) is not a solution but instead (13,52) is.
This means each of the four sides has a length of 13 units.
I hope this helps!
-TheBusinessMan
Answer:
P = 52
Step-by-step explanation:
51 = 13(4) 13x4=52
51 does not equal 52 there fore those values are immensely incorrect. However you may state 52 as the perimeter therefore allowing 52 1to equal 13(4).
New solution 52 =13(4)

Find how much interest $10,000 earns in 2 years in a certificate of deposit paying 8.5% interest compounded quarterly
The interest earned in 2 years is $
Answer:
Interest earned in two years is approximately $1,837
Step-by-step explanation:
A= P( 1+r/n)^nt
Where,
A= principal + interest
P= principal= $10,000
r= interest rate = 8.5%
t= Time = 2years
n = periods = 4
A= P( 1+r/n)^nt
= 10,000(1+0.085/4)^4*2
= 10,000( 1 + 0.0213)^8
= 10,000(1.0213)^8
= 10,000(1.1837)
=11,837
A= $11,837
The interest earned in two years is
A = p + I
A - P = I
$11,837 - $10,000 = I
$1,837 = I
I= $1,837
Interest earned in two years is approximately $1,837

What is PEMDAS?When resolving expressions containing several operations, the procedure to follow is denoted by the acronym PEMDAS. "Parenthesis," "exponents," "multiplication," "division," "addition," and "subtraction" are all represented by the letters P through E.
Given information:
The given equation is described as -3-(-8)-(-2) = x.
To solve the equation as per the PEMDAS rule:
First, we need to simplify the terms within the parentheses: -(-8) is the same as +8, and -(-2) is the same as +2. Therefore, the equation becomes:
-3 + 8 + 2 = x
Next, we can simplify the addition and subtraction from left to right:
-3 + 8 = 5
5 + 2 = 7
Therefore, the value of x is 7.

5.424 ≈ 5.420
Step-by-step explanation:5.424
↓4 = Tenth
↓2 = Hundredth
↓4 = Thousandth
The value of number after rounded to the nearest hundredth is, 5.42
In rounding a number into the nearest hundredth,
We look at the tenths place digit, If tenths place digit is 0, 1, 2, 3 or 4,
Then the number rounded to previous hundredth,
While, if the tenths place digit is 5, 6, 7, 8 or 9,
Then the number is rounded to next hundredth,
Here, the given number is,
⇒ 5.424
Here, Tenths place digit = 2,
Hence, it would be rounded to previous hundred,
Which is, 5.424 ≈ 5.42

The center of dilation is at the point of intersection of the lines through an image point and the corresponding pre-image point.
Here, A and A' are both on the line x=5. C and C' are both on the line y=2, so the center of dilation is (x, y) = (5, 2).
__
The point A' is half as far from (5, 2) as the point A is, so the scale factor of the dilation is 1/2. (A' is 3 units down; A is 6 units down from the center of dilation.)
