The area of the circle with radius 33 cm is 3419.5 square centimeters.
According to the question,
We have the following information:
Radius of the circle = 33 cm
We know that the following formula is used to find the area of the circle:
Area of the circle = π[tex]r^{2}[/tex] where r is the radius of the circle
There are two approximate values of π which are 22/7 and 3.14. In this case, we will use the value of π as 3.14.
So, we have the following expression:
Area of the circle = 3.14*33*33
Area of the circle = 3419.46 square centimeters
Rounding it off to one decimal point:
3419.5 square centimeters
Hence, the area of the circle with radius 33 cm is 3419.5 square centimeters.

Answer:
Step-by-step explanation:
so we need slope intercept form, which is y=mx+b ... just memorize this, you'll need it many many times
next we are told to find a line perpendicular to y= [tex]\frac{1}{8}[/tex]x+10
recall that the reciprocal of the slope will give us a perpendicular line with a sign change also.
then the slope m is:
m = -8
and we are given the point P(x1,y1) = ( -1,1)
now use the point-slope formula to find the equation to the line in the slope intercept form.
y-y1 = m(x-x1)
plug in our given info.
y-1 = (-8)(x-(-1))
y-1 = -8(x+1)
y-1= -8x -8
y = -8x -8+1
y=-8x-7
there is your slope intercept form of the equation :)

The square root of a number:
A square root of a number is a value of a number(other than the original number) that when multiplied by itself gives the original number. A square root of a number will be in the form of a².
Here are some examples of the square root of a number
√4 = 2 [ since 2 × 2 = 4 ]
√9 = 3 [ since 3 × 3 = 9 ]
Here we have
1. √90 - √40
2. (√35 - √42) / (√5 - √6)
3. 2√27 - √48
4. (√54 -√24)/√18 - √8
Each problem can be solved as given below
1. √90 - √40
= √9 × 10 - √4 × 10
= 3√10 - 2√10
= √10 = 3.16227
2. (√35 - √42) / (√5 - √6)
= (√5 × √7 - √7 × √6 ) / (√5 - √6)
= √7 [√5 - √6 ] / (√5 - √6)
= √7 = 2.64575
3. 2√27 - √48
= 2√9×3 - √16×3
= 6 √3 - 4√3
= 2√3 = 3.46410
4. (√54 -√24)/√18 - √8

= (3√6 - 2√6)/3√2 - 2√2 )
= (√6) / √2 )
= 1.73205
The resultant decimal numbers are
3.16227, 2.64575, 3.46410, and 1.73205.

Answers in bold
GivenGivenDefinition of midpointTransitive property of equalityAddition property of equalitySimplificationSubstitutionSegment addition postulateTransitive property of equalityDivision property of equality====================================================
Explanation:
Always start the proof with what you are given. It seems silly to repeat the given information, but it's just how all proofs are formed. This is to build from those given statements to lead to what we want to prove on the last line.
The term "midpoint" refers to splitting a segment into two equal smaller pieces. So for instance, if Q is the midpoint of PR, then the pieces PQ and QR are equal. Each smaller piece is half as long as PR.
The transitive property is the idea if A = B and B = C, then A = C. Think of it like substitution. Or you can think of a set of dominoes: A knocks down B, which knocks down C. Therefore A knocks down C.
The addition property of equality is where we go from A = B to A+C = B+C. I've added C to both sides. Adding the same thing to both sides will not change the equation. It keeps things balanced. When going from line 4 to line 5, we added PQ to both sides.
In line 6, we've gone from PQ+PQ to 2PQ.
In line 7, we replace PQ with QR on the right hand side. We use the substitution property here (refer to line 3 where we found PQ = QR)
Line 8 uses the segment addition postulate. If A,B,C are collinear, then AB+BC = AC. The point B doesn't necessarily need to be the midpoint.
Line 9 uses the transitive property again (we combine lines 7 and 8 to lead to line 9).
The final line has us divide both sides by 2 to get what is shown in the table. This is the division property of equality.
------------------------
Shortcut using informal logic:
PQ = QR
QR is half as long as QS
Therefore, PQ is also half as long as QS
Answer:
The last reason for [tex]PQ=\frac{1}{2}QS[/tex] is division property of equality
Step-by-step explanation:
The reason for [tex]PQ=\frac{1}{2}QS[/tex] can be evaluated as follows
For the statement [tex]Q[/tex] is the midpoint of [tex]\overline{PR}[/tex], the reason is given
For the statement [tex]R[/tex] is the midpoint of [tex]\overline{QS}[/tex], the reason is given
For the statement [tex]PQ=QR, QR=RS[/tex] , the reason is definition of midpoint
The midpoint of a line segment is the point that separates the line segment into two congruent parts.
For the statement [tex]PQ=RS[/tex] , the reason is transitive property
Transitive property says that if [tex]a=b[/tex], and [tex]b=c[/tex], then [tex]a=c[/tex]
In this statement [tex]PQ=QR, QR=RS[/tex], then [tex]PQ=RS[/tex]
For the statement [tex]PQ+PQ=PQ+RS[/tex] , the reason is addition property of equality
Addition property of equality says that if [tex]a=b[/tex], then [tex]a+c=b+c[/tex]
For the statement [tex]2PQ=PQ+RS[/tex] , the reason is combining of like terms of algebraic expression
Combining like terms is the process to add or to substract the coefficient of the terms
In this statement combining like terms is at the left side of the equation, [tex]PQ+PQ=2PQ[/tex]
For the statement [tex]2PQ=QR+RS[/tex] , the reason is substitution property
Substitution property of equality says that if [tex]a=b[/tex], then [tex]a[/tex] replaces [tex]b[/tex] in any equation, in this statement [tex]QR[/tex] replaces [tex]PQ[/tex]
For the statement [tex]QR+RS=QS[/tex] , the reason is substitution property and definition of midpoint
In this statement [tex]QR+RS[/tex] replaces [tex]2PQ[/tex], and [tex]QS[/tex] is the sum of two congruent parts [tex]QR+RS[/tex]
For the statement [tex]2PQ=QS[/tex] , the reason is substitution property
In this statement [tex]2PQ[/tex] replaces [tex]QR+RS[/tex]
For the statement [tex]PQ=\frac{1}{2}QS[/tex] , the reason is division property of equality
Division property of equality says that if [tex]a=b[/tex], and [tex]c\neq 0[/tex], then [tex]\frac{a}{c} =\frac{b}{c}[/tex]
In this statement [tex]\frac{2PQ}{2} =\frac{QS}{2}[/tex] or can be reduced into [tex]PQ=\frac{1}{2}QS[/tex]

The height of the arrow at 2.5 seconds is 71 feet.
Given:
An arrow released from a bow, traveling towards a target 200 yards away,reaches a max height of 42.6 ft in only 1.5 seconds.
1.5 seconds = 42.6 feet
divide by 1.5 on both sides.
1 sec = 28.4 feet
0.5 sec = 28.4/2
0.5 sec = 14.2 feet

Answer:
x=47
Step-by-step explanation:
Sum of all three angles of a triangle is 180 degrees
We know one angle which is 51 degrees
The second is 73 degrees since it’s corresponding angle is 73 degrees
73+51=124
Now subtract this from 180
180-124=56
We can set x+9 equal to this
X+9=56
-9. -9
x=47
