A student saves $3 dollars on August 1, $5 on August 2, $7 on August 3, and so on. How much will she save in August 20 ?
Delvig [45]
Here is your answer

Money saved on each successive day is-

$3, &5, $7....

Clearly it forms an AP,

where

a1= 3

common difference, d= 2

n=20

So,

using formula

Tn= a1+(n-1)d

T20= 3+(20-1)2

= 3+ 19×2

= 3+ 38

=41

So, money saved on August 20= $41

Sum of money saved upto August 20 =
n/2 (a1+T20)
= 20/2 (3+41)
= 10× 44
= $440

In triangle ABC below, sinC=h/a and sinA=h/c. Which of the following combines the two sine ratios into one equation?
LenaWriter [7]

We know:

sin(C)=\frac{h}{a}

and

sin(A)=\frac{h}{c}


These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms of h:

h=a(sin(C))

h=c(sin(A))


Now, because h=h (by the reflexive property), we can write:


a(sin(C))=c(sin(A))


This is our answer, A.
