In the triangle ABC, the height AN = 24 in, BN = 18 in, AC = 40 in. Find AB and BC.
Basile [38]

Step-by-step Answer:

AN is height, so A is perpendicular to BC.  (See image attached).

BN = 18

AN = 24

AC = 40

All as labeled.

ABN is a right triangle, with AB = sqrt(18^2+24^2)=sqrt(324+576)=30

ACN is a right triangle, with CN = sqrt(40^2-24^2)=sqrt(1600-576) = 32

=>

BC = BN + NC = 18 + 32 = 50

\frac{z}{3}+ \frac{12}{3}= \frac{5}{6} ⇒ \frac{z+12}{3}= \frac{5}{6}

z+12= \frac{5\cdot3}{6}=\boxed{2.5}

z=2.5-12

The first term of an Ap are x, 2x +1, and 5x+1 Find<br> x and the sum of the<br> l0 terms<br> first
bazaltina [42]

Answer:

145/2

Step-by-step explanation:

d=[2x+1-x] = [5x+1 -(2x+1)]

x+1=3x

x-3x=-1

-2x=-1

x=1/2

therefore first term is 1/2

second term is 2(1/2)+1= 2

common difference d is 2-1/2=3/2

sum of first n terms is n/2 [2a+(n-1)d] where n=10

sum of first 10 terms= 10/2[2×1/2+(10-1)3/2]

=5[1+(9)3/2] =5[1+27/2] = 5[29/2] =145/2

The formula is
A=p (1+r/k)^kt
A amount of the withdrawal?
P present value 4000
R interest rate 0.06
K compounded monthly 12
T time 2 years
A=4,000×(1+0.06÷12)^(12×2)
A=4,508.64

So it's c
