Jasper Wrote a formula for the area of triangle RST in terms of only the sides and angles. His steps are shown. Step 1: A =
1: A = 1/2 hs
Step 2: sin(R) = h/r
h = rsin(R)
Step 3: A = 1/2(r)(s)sin(R)

Identify the error in Jasper's work, then replace one term in his equation to write a correct equation for the area.

A= 1/2rs sin(R)

replace r with t

Step-by-step explanation:

correct on plato

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
