Answer:
97.425
Step-by-step explanation:
C▲RST/C▲XYZ=1/3
S▲RST/S▲XYZ=1/9
The area of ▲RST is 10.825
SO the are of ▲XYZ is 10.825*9=97.425
2x-2>8
2x>10
x = 10/2 = 5
x>5
since it is an absolute equation
it could also be x<-3
answer is x>5 or x<-3
Answer: (1,4) and (1,3) because the have the same x-value
Step-by-step explanation:
A function is defined so that for each input (known as the domain), there is no more than one output (known as the range).
Answer:
17) 750/9 and 18) 364
Step-by-step explanation:
17. Summation of 75*(0.1)^i from i=0 to infinity, that is equal to 75*(Summation of (0.1)^i). Summation of (0.1)^I is a geometric series with a sum of 1/(0.9)=10/9. Hence the series have a sum equal to 75*(10/9)=750/9
18) It's a series with sum=1+3+9+27+81+243=364
