He needs to take 5.5 grams of medications.
Step-by-step explanation:
I added 2.1 to 3.4 and got 5.5. *booyah*
Answer:
![y=9x-13](https://tex.z-dn.net/?f=y%3D9x-13)
Step-by-step explanation:
Slope-intercept form is
, where m is the slope, and b is the y-intercept. They tell us the slope is 9, so
. They also tell us that the y-intercept is (0,-13), which means that
. Plugging both of those values in gives us the equation:
![y=9x-13](https://tex.z-dn.net/?f=y%3D9x-13)
Answer:
2.1 centimeters thick.
Step-by-step explanation:
If he stacks them you can think of it in 2 ways:
1. Keep adding 0.3 cm until you add 7 times.
2. Multiplication, 0.3 multiplied by 7 will get you your answer!
Let's try the first way.
0.3+0.3=0.6+0.3=0.9+0.3=1.2+0.3=1.5+0.3=1.8+0.3=2.1
1 2 3 4 5 6 7
Now the second way.
0.3*7. Stacking them and then doing normal multiplication gets you 2.1 as well! And as a plus, it is much faster than adding and adding over and over.
So there you go! 2.1 centimeters. Hope this helped!
Answer:
a= x= 3, -1
b= x=1
c= (1, -8)
Step-by-by-step explanation:
For the show your work, you have to create the graph of the parabola. (attached image)
So firstly, you're gonna replace the T variable with 2.2, which is the time given to us. And so the equation is gonna look like this:
![2.2=2*3.14* \sqrt{ \frac{L}{32} }](https://tex.z-dn.net/?f=2.2%3D2%2A3.14%2A%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7B32%7D%20%7D%20)
and we will be solving for L.
The next thing you wanna do multiply 2 and 3.14 together, so your equation should look like this:
![2.2=6.28* \sqrt{ \frac{L}{32} }](https://tex.z-dn.net/?f=2.2%3D6.28%2A%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7B32%7D%20%7D%20)
After that, you're gonna want to square all the terms in this equation (2.2, 6.28, and
![\sqrt{ \frac{L}{32} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7B32%7D%20%7D%20)
) to remove the square root. Your equation will look like this
![4.84=39.4384* \frac{L}{32}](https://tex.z-dn.net/?f=4.84%3D39.4384%2A%20%5Cfrac%7BL%7D%7B32%7D%20)
Next up is you're gonna multiply 32, the reciprocal of 1/32, on each side so that the equation looks like this
![154.88=39.4384*L](https://tex.z-dn.net/?f=154.88%3D39.4384%2AL)
After, you're gonna divide 39.4384 on each side, and your equation should end up at
![3.927=L](https://tex.z-dn.net/?f=3.927%3DL)
. And assuming from your options, they are gonna want you to round to the nearest whole number, so the best option is 4 feet.
