First of all, you need to know these two equations:
a^b = c, which also translates into: log a c = b
Now, let us apply these equations here:
a here will stand for 2, b will stand for x, and c will stand for y.
So:
2^x = c, which translates into log2y = x
This means that the equation which is equivalent to y=2x is B. x = log2y
Answer:
the number of miles run on Thursday is 5.60 miles
Step-by-step explanation:
The computation of the number of miles run on Thursday is shown below
Here we assume the number of miles be x
3 ÷ 4 ÷ 1 = 4.2 ÷ x
3 ÷ 4 ÷ x = 4.2
3x = 16.8
x = 5.6
Hence, the number of miles run on Thursday is 5.60 miles
There are two (equivalent) formulas for the circumference of a circle:
C = 2 pi r, where r is the radius of the circle
C = pi d, where d is the diameter of the circle
In this particular problem, however, we're dealing with arc length. For the shown central angle "theta" = 160 degrees, the arc length is 42 cm.
Knowing this enables us to calculate the radius or diameter of the circle.
Arc length = s = (radius) (central angle, in radians, not degrees)
First, convert 160 degrees to radians: 160 deg pi rad
----------- * ------------ = (8/9) pi rad
1 180 deg
Then 42 cm = r *(8/9) pi rad
Solve for the radius (r): divide 42 cm by (8/9) pi rad
Then use the formula for circumference introduced earlier:
C= 2 pi r Substitute [42 cm / ( (8/9) pi rad )] for r.
Simplify your result, and you will then have the circumference, C, in cm.
Answer: No value for x
Step-by-step explanation:
Open the bracket
2x-6=2×+5; combine like terms
2×-2×=5+6
0=11
The answer to the equation is
y=1700s+18n and y is the total salary including monthly and number books sold
then to graph it just plug that equation I gave you into your graphing calculator and it will show you the graph. Or you can do it by hand and just make a S and N table and plug in values like starting with 0 or 1 and go up 0,1,2,3,4,etc. for each S and P and you will get the corresponding graph coordinate points to plot. Hope this helps! Please rate thank you!!
