Answer:
C. p = 1.72d
Step-by-step explanation:
The rate of change for the diver is 0.43. 0.43 x 4 = 1.72d.
The original annual simple interest rate, rounded to two decimal places, is 3.79%
What is the formula for simple interest?
The simple interest on a loan or deposit is determined as the principal multiplied by the simple interest rate and time
I=PRT
The first loan:
P=12 850.00
R=r(assume it is r)
T=4 years
I=12 850.00*r*4
I=51400r
The second loan was taken after 14 quarters the first was taken out, which is the same as after 3.5 years, hence, the interest on the second loan is only for a half a year
P=3 273.00
R=0.5r( half of the interest on the first loan)
T=0.5 years
I=3 273.00*0.5r*0.5
I= 818.25r
Total interest=51400r+818.25r
Total interest=52218.25r
total interest paid=1 980.00
1 980.00=52218.25r
r=1 980.00/52218.25
r=3.79%

That would be negative sixty-two over three
The answer is b
as the formula is
y-y1=m(x-x1)
y-6=-2/3(x-4)
In the question, they GIVE you the equation for the line:
y = 1.1 x + 1.37 .
When you look at the graph, you notice that the numbers
are actually thousands, so the equation is really
y = (1.1 thousand) x + (1.37 thousand)
or
y = 1,100 x + 1,370 .
The slope of the line is 1,100 .
Choice 'C' says that, because
the slope of any graph = (change in 'y') / (change in 'x') .
