The radius of a circle is 19m. Find its area to the nearest whole number.
1134.11m²
______----------________
Answer:
1134.11
Step-by-step explanation:
The problem with this equation is pi is an angle in radians. It has a never ending number of digits.
The area of a circle is basically a square r x r rotated through 180 degrees around the squares centre.
So the area can be written as 180 x 19 x 19 = 64980 degrees meters square.
This is a finite number. The area of a circle does not change. Pi r squared has an ever increasing result.
pi is a conversion factor between the finite areas of circles and the area in square units which can never have a result that is finite as squares cannot fill a circle, no matter how small.
To convert the round finite area to m squared you divide the area by 180/pi = 57.295779513 degrees per radian.
Area in degrees meters Squared 64980/ 57.295779513.
= 1134.1149479 radian meters squared.

What is a factorization, and how does it work?It is a method for dividing a polynomial into parts, each of which will be multiplied. At this time, the polynomial's value will be zero.
The equation for the expression is given below.
3x² + 4x = 6
3x² + 4x - 6 = 0
we know that the formula

How does the volume of a cylinder with a radius of 3 units and a height of 12 units compare to the volume of a rectangular prism with dimensions 16 units x 16 units x 9 units?
a. The volume of the cylinder is greater than the the volume of the prism
b. The volume of the cylinder is smaller than the volume of the prism.
C. The volume of the cylinder is the same as the volume of the prism
d.You cannot compare the volumes of different shapes
Answer:
The volume of the cylinder is greater than the volume of the prism.
Step-by-step explanation:
The Volume of a cylinder is given as:
= πr²h
Therefore, the volume of a cylinder with a radius of 3 units and a height of 12 units will be:
= πr²h
=3.14 × 3² × 12
=339.12
The volume of a rectangular prism with dimensions 3 units x 3 units x 12 units will be:
= Length × Width × Height
Based on the calculation, the volume of the cylinder is greater than the volume of the prism.
Answer:
B: The volume of the cylinder is smaller than the volume of the prism.
Step-by-step explanation:
In order to find the volume of the cylinder, we would use to formula [tex]\pi r^{2} h[/tex]. Substitute the given measures of the cylinder to get [tex]\pi[/tex]·3²·12. The simplified and calculated form would be 108 units cubed.
Now, we find the volume of the rectangular prism, which is [tex]l[/tex]·[tex]w[/tex]·[tex]h[/tex], or 16*16*9. This means the volume is 2304 units cubed.
Therefore, since 2304 un³>108 un³, answer choice b would be correct.

If mBE=119 and mBKE=93, find mUH.
Answer:
arc UH = 67°
Step-by-step explanation:
the measure of a chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle , then
[tex]\frac{1}{2}[/tex] ( BE + UH ) = ∠ BKE , that is
[tex]\frac{1}{2}[/tex] (119 + UH ) = 93° ( multiply both sides by 2 to clear the fraction )
119° + UH = 186° ( subtract 119° from both sides )
UH = 67°
Answer:
Step-by-step explanation:
∠HKU = ∠BKE {Vertically opposite angles}
∠HKU = 93°
Angles fromed by insecting chords equals half the sum of intercepting arcs.
[tex]\sf \angle HKU =\dfrac{1}{2}(arc \ HU + arc \ BE) \\\\ 93^ \circ = \dfrac{1}{2}(arc \ HU + 119)[/tex]
93 *2 = arc HU + 119
186 = arc HU + 119
186 - 119 = arc HU
arc HU = 67°

Is 3x^2-5x+205x^7 a perfect square?
7th Grade Math) 6. A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation 350 = 12(x + 20) to represent this situation. Solve the equation for x. Show your work or explain your answer. Write your answer as a sentence that describes what the variable x represents. Enter your answers and your work or explanation in the box provided.
Answer:
x=9.167
Step-by-step explanation:
12x+240=350
350-240 because you are getting rid of 240 to get 12x by itself so you must do it on the other side.
12x=110, then you do 12x/12 and 110/12
x=9.167
Answer: Approimately $9.16
Step-by-step explanation:
In this problem, you have to solve for x variable.
1. Distribute the 12 to the x + 20 which is 12x + 240
2. Subtract 240 from both sides so 350 - 240 is 110.
3. Now your equation is 110 = 12x
4. Divide 12 on both sides. But 12 doesn't go into 110 perfectly.
5. 110 divided by 12 is approximately 9.16.
The x represent how much the student has earn extra to get $350 in 12 months. The student has to earn 9.16 dollars every month on top of the 20 dollars.

Which of the following shows the correct first step to solve x^2 - 16x = -21 by completing the square?
A)x^2 - 16x + 64 = -21
B) x^2 - 16x + 64 = -21 + 64
C) x^2 - 16x + 16 = -21 + 16
D) x^2 - 16x + 8 = -21 + 8
Answer:
I believe the answer would be B) x^2 - 16x + 64 = -21 + 64
Step-by-step explanation:
When you're completing the square you take the "middle" term (in this case it's -16) and you divide it by two, then square it. By doing that for this problem you get 64 (16/2 = 8 - 8^2 = 64; signs don't matter in this case because you multiply 2 negatives). You have to add that 64 to BOTH sides so that the equation evens out.

This table gives the value of an investment for the first 14 years after the initial investment was made. The data can be modeled using an exponential function.
Years 2 4 6 8 10 12 14
Investment value $692 $952 $1,304 $1,813 $2,316 $3,256 $4,718
Based on the data, which amount is closest to the value of the investment 18 years after the initial investment? PLS HURRY I NEED THIS ANSWERED NOW, WILL GIVE 95 POINTS
Answer:
General form of an exponential equation: [tex]y=ab^x[/tex]
where:
a is the initial valueb is the growth factorx is the independent variabley is the dependent variableLet x = years
Let y = investment value
Use (2, 692) and (4, 952) to find a and b of the exponential equation:
[tex]ab^2=692[/tex]
[tex]ab^4=952[/tex]
[tex]\implies \dfrac{ab^4}{ab^2}=\dfrac{952}{692}[/tex]
[tex]\implies b^2=\dfrac{238}{173}[/tex]
[tex]\implies b=\sqrt{\dfrac{238}{173}}=1.17\:\textsf{(nearest hundredth)}[/tex]
[tex]\implies ab^2=a\left(\dfrac{238}{173}\right)=692[/tex]
[tex]\implies a=\left(\dfrac{59858}{119}\right)=503.01\:\textsf{(nearest hundredth)}[/tex]
Therefore, the exponential equation is:
[tex]y=503.01(1.17)^x[/tex]
18 years after the initial investment is when [tex]x=18[/tex]:
[tex]\implies 503.01(1.17)^{18}=8490[/tex]
Therefore, the amount closest to the value of the investment 18 years after the initial investment is $8490
(If you use the exact values for a and b rather than the rounded values, the amount is $8879)

Solve the system of equations.
5x – y = 5
5x2 – y = 5
Answers:
(0, 5) and (0, –5)
(1, 0) and (0, –5)
(2, 5) and (1, 0)
(3, 10) and (2, 15)
Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
