Answer:
Step-by-step explanation:
For this equation: a=3, b=4, c=2
3x2+4x+2=0
Step 1: Use quadratic formula with a=3, b=4, c=2.
x= −b±√b2−4ac / 2a
x= −(4)±√(4)2−4(3)(2) / 2(3)
x= −4±√−8 / 6

Answer:
She deposited
dollars
Step-by-step explanation:
Given -
Rate of interest
%
Rate of interest compounded quarterly
Time period
years
Amount after
years
dollars
We shall use the following equation for solving this question
![A = P (1 + r)^t](https://tex.z-dn.net/?f=A%20%3D%20P%20%281%20%2B%20r%29%5Et)
Where A is the final amount after time period t
P is the principal amount
r is the rate of interest
and t is the time period
Substituting the given values in above equation, we get -
![4837.65 = P (1 +\frac{3.2}{4*100})^{4 *5}\\4837.65 = P (1 +0.008)^{20}\\P = \frac{4837.65}{1.7276} \\P = 4124.998](https://tex.z-dn.net/?f=4837.65%20%3D%20P%20%281%20%2B%5Cfrac%7B3.2%7D%7B4%2A100%7D%29%5E%7B4%20%2A5%7D%5C%5C4837.65%20%3D%20P%20%281%20%2B0.008%29%5E%7B20%7D%5C%5CP%20%3D%20%5Cfrac%7B4837.65%7D%7B1.7276%7D%20%5C%5CP%20%3D%204124.998)

Answer:
<u>953.78in^3</u> of grain
Step-by-step explanation:
You use the equation π r^2 h to find the volume of the cylinder
r = radius of the base = 9/2
= 4.5 in and the height h = 15 in
the volume is 3.14 * 4.5^2 * 15
= 953.78 in^3.
Quotient means division, so you can immediately throw out C as an answer choice. the order of this question is important because it lists it exactly how you're supposed to write it: the quotient of 3 and m, which is 3 divided by m.
your answer is B. 3 divided by m equals 1.9!!
