Answer:Amount = 10,002.21
Step-by-step explanation:4 x 5 = 20 times
2.-
Principal = 5,000
Interest rate per yr = 3%
Compounded times per yr = 4
Time in years = 5
The formula is amt = p*(1 + r/n) ^ (n*t),
thus
Amount = 5,805.92
3.-
If Time in years = 23.2
then
Amount = 10,002.56
4.-
Principal = 5,000.00
Interest rate per yr = 5.82%
Compounded times per yr = 4
Time in years = 12
Answer:
x = -4
Step-by-step explanation:
logs (8 - 3x) = log20
Since we are taking the log on each side
log a = log b then a = b
8 -3x = 20
Subtract 8 from each side
8 -3x-8 =20 -8
-3x = 12
Divide by -3
-3x/-3 = 12/-3
x = -4
It’s 27 for sure because (7-5) is 2 times that by the power of 2 is 4 times that by 6 is 24 and 3 +24 is 27
Answer:
y = x² + 6x + 8
Step-by-step explanation:
The zeros ( x- intercepts ) of the graph are x = - 4 and x = - 2, thus
the factors are (x + 4) and (x + 2) and the function is the product of the factors.
y = a(x + 4)(x + 2) ← a is a multiplier
To find a substitute (0, 8 ) the y- intercept into the equation
8 = a(0 + 4)(0 + 2) = a(4)(2) = 8a ( divide both sides by 8 )
a = 1, thus
y = (x + 4)(x + 2) ← expand using FOIL
= x² + 6x + 8
