Scott invested $1600 into a retirement account that earns 2.4% interest compounded monthly. What will the balance of the account be after 30 years? Round answer to the nearest hundredth
Answer:
Step-by-step explanation:
[tex]V=P\left(1+\ frac{r}{c}\right)^{ct}\\ \\ V=1600\left(1+\frac{0.024}{12}\right)^{12(30)}\\ \\ V=\$ 3284.73[/tex]
Answer:
The interest is $13824 and the amount is $15424.
Step-by-step explanation:
i did 2.4% of 1600 which is 38.4 then i took that number and multiplied it by 12 (months in a year) and got 13824
I am not sure if you are supposed to add in the original amount, and if you are, it would be 15424
Hope this helped!

The triangle that it formed is given in the figure,
Now first we have to find angle A,
sin(A) =perp/hyp = 1.3/5 = 0.26
now we get ,
Angle A = 15 degree
now using ,
tan(15) = perp/base = 1.3/distance
distance = 1.3/tan(15)
distance =1.3/0.27
distance = 4.8 m
Whats the slope of (-3,4) (0, 0)
Answer:
slope = [tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. [tex]m[/tex] represents the slope. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (-3, 4) and (0, 0) into the formula appropriately and solve:
[tex]m= \frac{(0)-(4)}{(0)-(-3)} \\m = \frac{0-4}{0+3} \\m = \frac{-4}{3}[/tex]
Thus, the slope is [tex]-\frac{4}{3}[/tex].
