Step 1:
Find how many microliters of blood there are in a 140lb person.
=140 * (2.7*10^4)
=140*(2.7*10*10*10*10)
=140*27,000
=3,780,000 # of microliters of blood in a 140lb person
Step 2:
Find how many white blood cells in a 140lb person
=3,780,000* (7*10^4)
=3,780,000*(7*10*10*10*10)
=3,780,000*(70,000)
=264,600,000,000 # of white blood cells in a 140lb person
(or 2.646 * 10^11 using scientific notation)
Hope this helps! :)
Answer:
x<7
Step-by-step explanation:
Answer
8x3+27
Step-by-step explanation:
(2x+3)(4x2−6x+9)
=(2x+3)(4x2+−6x+9)
=(2x)(4x2)+(2x)(−6x)+(2x)(9)+(3)(4x2)+(3)(−6x)+(3)(9)
=8x3−12x2+18x+12x2−18x+27
=8x3+27
Answer:
y-intercept is 1
Step-by-step explanation:
We need to find the equation of the line first.
<h3>Gradient</h3>
The gradient is found using the formula:
![m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
![m=\frac{-1-2}{8--4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-2%7D%7B8--4%7D)
So the equation is y =
x + c
<h3>Finding c</h3>
To find c we need to substitute the value of x and y into the equation:
-1 =
+ c
-1 = -2 + c
1 = c
And c is the y-intercept so it is 1
