Answer:

The answer is y = 5.25

Step-by-step explanation:

-2.3 + 1.6y = 6.1

1.6y = 6.1 + 2.3

1.6y = 8.4

y = 8.4/1.6

Principal==12,000 interest is 5.6%..for 5 years.how much interest will I pay.​
Keith_Richards [23]

Answer:

Step-by-step explanation:

IF Simple interest; Simple Interest formula would be

<em>S.I = Principal *rate * time</em>

Principal = 12,000

rate = 5.6% or 0.056 as a decimal

time = 5 years

therefore S.I = 12,000 * 0.056 * 5

S.I = 3,360

Therefore, based on simple interest, you will pay $3,360 in interest.

IF Compound interest, the formula would be;

Compound interest = [ Principal *(1+rate )^t ] - Principal

= [ 12,000*(1+0.056)^5 ] -12,000

= [12,000*1.313165883] - 12,000

=15,757.9906 -12,000

= 3,757.9906

Therefore, based on compounding, you will pay $3,757.9906 in interest.

An archway will be constructed over a walkway. A piece of wood will need to be curved to match a parabola. Explain to Maurice ho
mariarad [96]
Ok

so the focus is on the opening side of the parabola

so for a vertex of (h,k)
opening up and down
(x-h)²=4p(y-k)
p is the distance from vertex to focus
it is also the distance from the vertex to the closes point on directix
2p=distance from focus to directix

p is positive if the focus is above the directix

ok
y=9 and (7,6)
9>6
directix is above the vertex
p is negative
find distance
from 9 to 6 is 3
3=2p
1.5=p
p is negative
and the vertex will be 1.5 above the focus and 1.5 below the directix
vertex is (7,7.5)

(x-7)²=4(-1.5)(y-7.5) is de equation
