Answer:
The area of the new circle is 804.57 cm^2
Step-by-step explanation:
In this question, we are interested in calculating the area of the new circle of the radius of the old circle was doubled.
Let’s calculate the former radius first;
Mathematically;
Area of a circle = π * r^2
Thus;
201.06 = π * r^2
r^2 = 201.06/π
r^2 = 63.999
r = √63.99
r = 8 approximately
Now let’s double this radius and it becomes 2 * 8 = 16 cm
The new area will be ;
22/7 * 16 * 16 = 804.57 cm^2
If sin Ѳ = cos 40, find the value Ѳ
Answer:
Θ = 50°
Step-by-step explanation:
Using the cofunction identity
cosx = sin(90 - x)
Given
cos40° = sin(90 - 40)° = sin50° ⇒ Θ = 50°
Answer:
Ѳ = 50
Step-by-step explanation:
Sin Ѳ = cos 40
[tex]Ѳ = \sin ^{ - 1} ( \cos(40) ) [/tex]
Simplify
[tex]Ѳ = sin^{ - 1} (0.7660444431) \\Ѳ = 50[/tex]

Can someone help me out?
Answer:
So the value of s = 7 cm
Step-by-step explanation:
We know that, Area of a triangle = 1/2 * b * h
So, base = 24 cm
height = s
Area = 1/2 * b * h
=>84 = 1/2 * 24 * h
=>84 = 12 * h
=>84 / 12 = h
=> 7 = h (in cm)

f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5)
Answer:
Ste = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5) = -12n? – 11n + 15
f (n) = -n(12n + 11) + 15
f (n) = (-4n+ 3) (3n + 5)
f(n) = -(4n + 3) (3n + 5)
f(n) = (4n + 3)(-3n+ 5)vp-by-step explanation:
To find the zeros of function, write in factors form,
[tex]f(n)=(-4n+3)(3n+5)[/tex]
Quadratic function :Given function is,
[tex]f(n)=-12n^{2} -11n+15[/tex]
We have to break into factor form to find the zeros of function.
[tex]f(n)=-12n^{2} -11n+15\\\\f(n)=-12n^{2}-20n+9n+15\\ \\f(n)=-4n(3n+5)+3(3n+5)\\\\f(n)=(-4n+3)(3n+5)[/tex]

Give brainiest please ;-;
Answer:
different variables represent unknown numbers.
Step-by-step explanation:
For example the equation 5x = 15
X is a variable that represents an unknown number. To get the unknown number in the example you need to divide 15 by 5 and 5 by 5 to get X alone and then X will equal 3.
So 5×3=15

Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
You can combine the two red shaded areas to get a larger portion with an angle of 120°.
The total degrees in a circle is 360° and since [tex]\frac{120}{360} =\frac{1}{3}[/tex],
The area of the combined red shaded area is [tex]\frac{1}{3}[/tex] of the entire area of the circle.

Which of the Following is the solution to 4|x+3| greater than equal to 8? Options are as followed: A.x less then equal to -5 or x greater than equal to -1 B. x greater than equal to -1 C.x less then equal to -5 and x greater than equal to -1 D. x greater then equal to -5 and x greater then equal to -1
Answer:
A
Step-by-step explanation:
4|x+3| >= 8
Divide both sides by 4
4|x+3| / 4 >= 8/4
|x+3| >= 2
Rewritten as
-2 >= x + 3 >= 2
Subtract 3 from all sides
-2 - 3 >= x + 3 - 3 >= 2 - 3
-5 >= x >= -1
Or
-1 <= x <= -5
x less then equal to -5 or x greater than equal to -1

Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15
10/15 =15x/15
2/3 =x

y=(x+1)^2
Step-by-step explanation:
we have the following
[tex]x=1;y=4\\\\x=2;y=9\\\\x=3;y=16\\\\x=4;y=25[/tex]
the values of y are squares so we can write
[tex]x=1;y=2^{2} \\\\x=2;y=3^2\\\\x=3;y=4^2\\\\x=4;y=5^2[/tex]
so as you can see when
[tex]x=n;y=(n+1)^2[/tex]
so our relation is
[tex]y=(x+1)^2[/tex]
