Answer:
1/2x
Step-by-step explanation:
It's exactly in between the steep slope and the flat line and the steep line's slope is x or 1x.
To solve this question simply break down the variables and numbers one at a time.
Here the word a number can be used to describe any number so let’s call that a variable x.
Increased would be addition in mathematics.
Next put everything together.
5x + 6 = -2
5x = -8
X = -8/5.
This is the value of x
The answer is A
First convert 5 3/4 from a mixed fraction into a complex fraction.
5 x 4 = 20
20 + 3 = 23
23/4 = 5.75
5.75 inches per student so you must multiple that by 7 students
5.75 x 7 = 40.25
Easy
equation is
f(x)=2ˣ
where x=number of hours elapsed
after 6 hours
f(6)=2⁶=64 bacteria
to solve for 1024
1024=2ˣ
take ln of both sides
ln(1024)=ln(2ˣ)
ln(1024)=x(ln(2))
divide both sides by ln(2)
ln(1024)/ln(2)=x
using calculator
10=x
or you could recognize that
1024=2¹⁰
or keep divising 1024 by 2
10 hours for 1024 bacteria
Let the centre be O and the line with one end point at the centre and another at the chord CD touches the chord at S .
So CS is the half of 36.7 = 18.35
![sin \angle COS = \frac{18.75}{21.8}](https://tex.z-dn.net/?f=%20sin%20%5Cangle%20COS%20%3D%20%5Cfrac%7B18.75%7D%7B21.8%7D%20)
![\angle COS = sin^{-1}(\frac{18.75}{21.8}) =59.35 degree\\](https://tex.z-dn.net/?f=%20%5Cangle%20COS%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B18.75%7D%7B21.8%7D%29%20%3D59.35%20degree%5C%5C%20%20)
Therefore,
![\angle COD =2*59.35 =118.7](https://tex.z-dn.net/?f=%20%5Cangle%20COD%20%3D2%2A59.35%20%3D118.7%20)
Therefore the measurement of arc CD is 118.7 degree.
