Answer: Answer:
length= 53.22
width= 17.74
Step-by-step explanation:
Assuming the tank is a rectangular prism, then the formula for its volume will be:
volume= height* length * width
v= h * l * w
The length is equal to 3 times width, to put into the equation it will be:
l= 3w
We know that volume is 315 cubic feet and height is 3 feet, if you substitute all value into the equation we can find out the width.
v= h * l * w
315= 3 * l * w
945 = 3w * w
3w^2 = 945
w^2= 315
w= 17.74
Then we can find out length
l= 3 * w
l= 3* 17.74= 53.22
Step-by-step explanation:
Sum of n terms = a1 (r^n-1/ (r-1)
Sum of first one = 3 * (4^5 - 1) / 3 = 1023
.. 2nd = 5 * (6^2 - 1) / 5 = 35
.. 3rd = 5 ^4 - 1 / 4 = 156
.. 4th = 4 * (5^4 - 1) / 4 = 624
So in increasing order its 2nd, 3rd, 4th and first.
Answer:
3. -6/2
4. 7/3
Step-by-step explanation:
if this is to find the slope you use the formula which is
y1-y2/x1-x2
