Answer:
1=5 so x=4.5
Step-by-step explanation:
so 11x-9=7x+9
4x=18
x=18/4
x=4.5
Answer:
Radius = r = 7.5
Diameter = d = 15
Circumference = C = 15π
Step-by-step explanation:
We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.
Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.
Circumference of the circle = C = 2πr
Using the value of radius(r), we can write the circumference as:
C = 2π(7.5) = 15π
Answer:
when the survey was initially conducted the average sales of smartphones was 1.7 million units
Step-by-step explanation:
The average annual sales of smartphones is given by function
Exponential growth function is given by
Where a= initial value
b = growth factor , b= 1+r where 'r' is the growth rate
x is the time period
Now we compare f(x) with P(n)
the value of a= 1.7 that is the initial value.
So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
Answer:
The correct answer is 0 or 5
Step-by-step explanation:
In order to solve this, solve for 0.
2x^2 = 10x
2x^2 - 10x = 0
Now factor the polynomial.
x(2x - 10) = 0
Now set each piece individually equal to 0.
x = 0
2x - 10 = 0
2x = 10
x = 5
Answer:
83.241
Step-by-step explanation:
To divide by 10, move the decimal point one place left.
832.41 ÷ 10 = 83.241
