1) b^2 - 4ac = ( -2 )^2 - 4×( 0.5 ) × 2 = 4 - 4 = 0;
2) b^2 - 4ac =( -5)^2 - 4×2×20 = 25 - 160 = - 135 ;
Answer:
The amount is 5,955.08
Step-by-step explanation:
Here, we want to calculate compound interest
We can find this by using the compound interest formula
A = P( 1 + r/n)^nt
A is amount
P
is the principal = 5,000
r is the interest rate = 6% = 6/100 = 0.06
n is the number of times per year in which the interest is compounded = 1
t is the number of years = 3
Substituting these values;
A = 5,000(1 + 0.06/1)^3(1)
A = 5000(1.06)^3
A = 5,955.08
Answer:
y= -2/3x+10
Step-by-step explanation:
-2/3=slope, x-intercept=5 = (5,0)
formula is y-y1=m(x-x1)
(5,0) ---> 5=x1 0=y1
y-0= -2/3(x-5)
y-0= -2/3x+10
+0 +0
y= -2/3x+10
Answer:
Step-by-step explanation:
1. - 3x + 32 = - x - 12
-3x + x = - 12 - 32
-2x = - 44
x = 44/2 = 22
2. 8x + 16 = x + 9
8x - x = 9 - 16
7x = - 7
x = - 7/7
= - 1
3. 3x + 2 = 2x - 55
3x - 2x = - 55 - 2
x = - 57
It’s in the picture below
