The area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².
What is the Area of a Circle?Area of circle = πr², where radius is r.
Thus, given that a circle has radius (r) = 1 units
Area of the circle = π(1²) = π units²
If the radius is given as r, the area of the circle remains as πr².
Therefore, the area of a circle that has a radius that is given as r is πr² units², while if the raidus is r, its area would be π units².

Step-by-step explanation:
We must do the first derivative test. Here is the steps:
Step 1: Differentiate the polynomial once
we get
[tex]2 {x}^{2} - 2x - 112[/tex]
Step 2: Set this equal to zero and solve for x.
[tex]2 {x}^{2} - 2x - 112 = 0[/tex]
[tex] {x}^{2} - x - 56 = 0[/tex]
[tex](x - 8)(x + 7) = 0[/tex]
[tex]x = 8[/tex]
[tex]x = - 7[/tex]
The solutions are your critical points.
So our critical points are (8,-7).
Step 3: Plot -7 and 8 on a number line. First, pick a number lesser than -7 and plug plug in the derivative function.
Let use -10.
[tex]( - 10 - 8)( - 10 + 7) = 54[/tex]
Since that number is positive, this means are increasing when (-oo,-7)
Next, pick a number greater than 8. Let use 9.
[tex](9 - 8)(9 + 7) = 16[/tex]
Since that is positive, the interval is increasing whe (8,oo)
C. If we pick a number in between -7 and 8, we will get a negative number which means the function is decreasing on interval (-7,8)

Kelsey bought some roses and tulips.She bought twice as many tulips as roses. Roses cost $5 each. Tulips cost $2 each .Kelsey spent $36 total. How many of each kind of flower did Kelsey buy ?
Answer: 4 roses and 8 tulips.
Step-by-step explanation: Each rose costs $5, so she bought 4 of them, which is $20 so far. Since she already bought 4 roses, she bought twice that amount for tulips, which is 8. Each tulip costs $2, so that's $16. Add both $20 and $16 and you have $36.

Part: 0 / 30 of 3 Parts Complete Part 1 of 3 What proportion of the diameters are less than 24.3 millimeters? The proportion of the diameters that are less than 24.3 millimeters is .
Answer:
Z = x - µ / ∂
= 24.2 – 24.6 / 0.07
=-0.4/ 0.07
= -5.71
Step-by-step explanation:
Solution:
Mean = µ = 24.4mm
Standard deviation = ∂= 0.07 mm
(a) Diameter less than 24.3 mm
P(x < 24.3)
The formula for normalized z value:
Z = x - µ / ∂
= 24.3 - 24.4 / 0.07
= - 0.1 / 0.07
= -1.4286
P(z < -1.428) = 1 – p ( z > -1.428)
= 1 – p( z < 1.42)
=1 – 0.4233
= 0.5767
(b) Diameter greater than 24.6 mm
P( x > 24.6)
The formula for normalized z value:
Z = x - µ / ∂
= 24.3 – 24.6 / 0.07
=-0.3 / 0.07
= - 4.285
P( z > -4.285) = 1 – p(z < -4.285)
= 1 – p ( z > 4.285)
=
(c) Diameter between 24.2 and 24.5 mm.
P(x > 24.5)
Z = x - µ / ∂
= 24.5 – 24.6 / 0.07
=-0.1/ 0.07
= -1.4286
P(z < -1.428) = 1 – p ( z > -1.428)
= 1 – p( z < 1.42)
=1 – 0.4233
= 0.5767
P(x < 24.2)
Z = x - µ / ∂
= 24.2 – 24.6 / 0.07
=-0.4/ 0.07

L × W = 300 : area , L is the length and W is the width. 2 L + 2 W = 70 : perimeter L = 35 - w : solve for L (35 - W) × W = 300 : substitute in the area equation W = 15 and L = 20 : solve for W and find L using L = 35 - w.
