Answer: she will have $2042.4 have in the account after 1 year.
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $2000
r = 2.1% = 2.1/100 = 0.021
n = 12 because it was compounded 12 times in a year.
t = 1 year
Therefore,
A = 2000(1 + 0.021/12)^12 × 1
A = 2000(1 + 0.00175)^12
A = 2000(1.00175)^12
A = $2042.4
We know that
if <span>90° < θ < 180°
</span>then
θ--------------> belong to the second quadrant
so
tan θ is negative
sin² θ + cos² θ=1----------> sin² θ=1-cos² θ----->sin² θ=1-(-2/9)²
sin² θ=1-(4/81)------> 77/81----------> sin θ=√(77/81)------> √77/9
sin θ=(√77)/9
tan θ=sin θ/cos θ------> [(√77)/9]/[-2/9]-------> -√77/2
the answer is the option
<span>A) -77sqroot/2</span>
The slope of a line in form ax+by=c is -a/b
the yint of the line is c/b
so
-6x-5y=15
slope=-(-6)/-5=6/-5=-6/5
yint is 15/-5=-15/5=-3
slope=-6/5
yint is -3
or you could just do slope intercept and solve for y
y=mx+b
m=slope
b=yintercept
slope=-6/5
yint is -3
Answer:
True
