Answer:
x=7
Step-by-step explanation:
171/3 is 57. the three consecutive numbers are 56, 57 and 58.
244/4 is 61. the even integers are 58, 60, 62 and 64
X=5 because 4x5=20 and 20-4=16
Answer: Kriz should pay $50,100 at the end of the term.
Step-by-step explanation:
If the interest is compunded quarterly, then the accumulated amount after t years will be:
, where P= principal value , r = rate of interest .
Given: P= 50,000 , r= 5% = 0.05, t= 4 years
Then,
Hence, Kriz should pay $50,100 at the end of the term.
B. First off , standard form of a 2nd degree equation is Ax^2 + Bx + C. So look at the coefficient of Ax^2 which is -2.
If positive, the parabola opens up and has a minimum.
If negative, the parabola opens down and has a maximum.
A. To find the vertex (in this case maximum),
Graph the equation -OR—
make a table. — OR—
Find the zeroes and find the middle x-value
-2x^2 - 4x + 6
-2(x^2 +2x - 3 = 0
-2 (x - 1) ( x + 3)=0
x - 1 = 0. x + 3 = 0
x = 1. x = -3. So halfway would be at (-1, __).
Sub in -1 into original equation -2x^2 -4x + 6 … -2(-1)^2 -4(-1) + 6 = -2 +4 +6 = 8
So the vertex is (-1,8)
