Answer:
Let R = radius of big circle
r=radius of small circle
A1=Area of small circle
A2=Area of big circle
R=9r
A1=50cm^2
A1=pi*r*2
A2=pi*R^2
A2=pi*(9r)^2
A2=81*pi*r^2
A2=81*A1
A2=4050cm^2
Hence the big circle has area of 4050cm^2
Step-by-step explanation:
The answer is 4050 cm²
What is the area and circumference of a circle?The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.
Given here: The radius of a circle is 9 times the radius of a smaller circle. And area of the smaller circle is 50 cm² then let the area of the larger circle be x
π9²/π1² =x/50
x=4050
Hence, The answer is 4050 cm²

Which is the correct equation for the graph of f(x), a transformation of the graph of g(x) = log2x? A. f(x) = -log2(x + 2) B. f(x) = log2(x − 2) + 2 C. f(x) = -log2x + 2 D. f(x) = log2x − 2
The equation of the function f(x) is: f(x) = log2(x − 2) + 2 option (B) f(x) = log2(x − 2) + 2 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a parent function:
g(x) = log₂x
Transformation:
g(x) → g(x) + 2
G(x) =log₂x + 2
The function will shift upside by 2 units.
G(x) → G(x-2)
f(x) =log₂(x-2) + 2
The function will shift right side by 2 units.
Thus, the equation of the function f(x) is: f(x) = log2(x − 2) + 2 option (B) f(x) = log2(x − 2) + 2 is correct.

my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)let's solve
let my mother's and sister's age be x and y respectively
according to the first condition,x=4y....(I)
according to the 2nd condition,x+5=2(y+5×2).....(ii)
so the system of linear equations is
x=4y
x+5=2(y+5×2)
gets from the second equation
x+5=2(y+10)
x+5=2y+20
4y+5=2y+20 (as x=4y)
2y=15
y=7.5
so the age of mother is
x=4.(7.5)
x=30

When the domain of a function has an infinite number of values, the range always has an infinite number of values. True or false
Answer:
Thus, the statement is False!
Step-by-step explanation:
When the domain of a function has an infinite number of values, the range may not always have an infinite number of values.
For example:
Considering a function
[tex]f(x) = 5[/tex]
Its domain is the set of all real numbers because it has an infinite number of possible domain values.
But, its range is a single number which is 5. Because the range of a constant function is a constant number.
Therefore, the statement ''When the domain of a function has an infinite number of values, the range always has an infinite number of values'' is FALSE.
Thus, the statement is False!
find the measure indicated
Answer:
B) 69°
Step-by-step explanation:
The missing measure is supplementary angle of 111° which means their sum is equal to 180°
180 - 111 = 69.

Does anyone know how to do this..
Answer:
x = 45°
Step-by-step explanation:
From the triangle given in the picture,
It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.
By the property of isosceles triangle,
Opposite angles of the equal sides are equal in measure.
By triangle sum theorem,
x + x + 90° = 180°
2x + 90 = 180
2x = 180 - 90
x = [tex]\frac{90}{2}[/tex]
x = 45°

Find the equation of the line. y=___x+___
Answer:
y = -1/3 -6
Step-by-step explanation:
y intercept is -6 because thats where the line hits the y intercept
the slope is -1/3 because of rise over run
what is the slope of a line that is defined by x+y=10
Answer:
-1
Step-by-step explanation:
Turn into slope-intercept form.
x + y = 10
~Subtract x to both sides
y = 10 - x
~Reorder
y = -x + 10
We know that slope-intercept form is y = mx + b where m = slope and b = y-intercept. Thus, the slope is -1.

If 96 people attend a concert and tickets for adults cost $3.75 while tickets for children cost $3.50 and total receipts for the concert was $350.50, how many of each went to the concert?
Answer: 58 adults and 38 children went to the concert.
Step-by-step explanation:
Let x= adults , y= children
As per given ,
x+y = 96 (i)
3.75x+3.50y = 350.50 (ii)
Multiply 3.75 to (i) , we get
3.75 x + 3.75y = 360 (iii)
Eliminate (ii) from (iii)
[tex]3.75 y-3.50y= 360-350.50\\\\\Rightarrow\ 0.25y= 9.5\\\\\Rightarrow\ y=\dfrac{9.5}{0.25}\\\\\Rightarrow\ y= 38[/tex]
put this in (i) , x+38 = 96
x= 96-38 = 58
So, 58 adults and 38 children went to the concert.
