Answer:
the third one
Step-by-step explanation:
Vertex (0,-10)
Axis of sysmmetry x=0
First write out the multiples of 6 and 26. Then find the common multiple they share that is immediately less than 85. (I do 26 first since it will have less multiple and it will give me an idea what to look for within the multiples for 6)
26: 26, 52, 78 (anything more will be over 85 and we need a number less than 85)
6: 6, 12, 18, 24, 30, 36, 42, 48, 56, 72, 78 (I stopped at 78 since any number after this will be larger than 85)
I now look to find the multiple that both 26 & 6 shares that is also less than 85 and it land me on the number 78!
The Answer: 78
Hope this helps!
Answer:
Number of glass panel in 16th row = 64
Step-by-step explanation:
Given:
Number of glass panel in first row = 4
Each next row added number of glass panel = 4
Find:
Number of glass panel in 16th row
Computation:
An = a + [n-1]d
An = given term = A16
a = first term = 4
n = number of term = 15
d = Common difference = 4
An = a + [n-1]d
An = 4 + [16-1]4
An = 4 + [15]4
An = 4 + 60
An = 64
Number of glass panel in 16th row = 64
Answer:
B. RY/RS=RX/RT=XY/TS
Step-by-step explanation:
In the picture attached, △RST and △RYX (which are similar) are shown
The options are:
Given that the triangles are similar, then their sides are proportional. Then, there is some constant k, which satisfies:
k*RS = RY
k*RT = RX
k*TS = XY
This can be rewritten as:
k = RY/RS = RX/RT = XY/TS
