Answer:
The rate is 2.4% per year.
Step-by-step explanation:
The basic formula is Dividend equals Principal times rate times time.
Time is usually the number of years
Dividend means the same as Interest, but we can use D instead if <em>I </em>which is confusing. So D=Prt
Principal is the original amount invested or deposited
You are given D = 96, P = 800 t = 5
r is unknown, that's what you have to solve to find
Put the numbers into the formula: 96 = (800) × r × (5)
Divide: 96/(800)(5) =r That's 96 ÷ 4000 = r Calculate that to get 0.024 and change the decimal to a percent.
That means the rate of interest is 2.4%
Answer: C, I think!
Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.
For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.
For B, pi to the second power over 3 equals 3.2897, so that’s not it too!
For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!
I’m only in 7th grade, so I’m sorry if it’s wrong!

Sorry if I made typos!
1.92 × 10 × 10 = 192
1 × 10 × 10 = 100
192/100

Answer:
b = y-intercept; The equation is y = mx + b. The x and y variables remain as letters, but m and b are replaced by numbers (ex: y = 2x + 4, slope = 2 and y-intercept = 4). The following video will show a few examples of understanding how to use the slope and intercept from an equation.
Vertex (4, -13) y = x^2 - 8x + 3 x-coordinate of vertex: x = -b/(2a) = 8/2 = 4 y-coordinate of vertex: y(4) = 16 - 32 + 3 = -13 Vertex (4, -13) To find y-intercepts, make x = 0 --> y = 3 To find x-intercepts, solve the quadratic equation y = 0 Use the improved quadratic formula D = d^2 = b^2 - 4ac = 64 - 12 = 52 --> d = +- 2sqrt13 There are 2 x-intercepts (2 real roots): x = -b/(2a) +- d/(2a) = 8/2 +- (2sqrt13)/2 = 4 +- sqrt13 graph{x^2 - 8x + 3 [-40, 40, -20, 20]}
