Step-by-step explanation:
Answer:
-1/5
Step-by-step explanation:
Perpendicular lines have slopes that are the opposite reciprocal of one another.
The slope of line t is the opposite reciprocal of the slope of line s:
slope of t = -1/(slope of s)
slope of t = -1/5
Answer:x^2 + 9x + 20
Step-by-step explanation:
You could just multiply (x+4)(x+5) and get x^2 + 9x + 20, but judging from the picture, it looks like they want you to split it into 4 rectangles
x^2 +4x+ 5x + 20 =x^2 +9x + 20, just like (x+4)(x+5)
Answer: (1) mean = 9.46; standard deviation = 3.74
Step-by-step explanation:
Answer:
Step-by-step explanation:
a). Ratio of OP and RT = ![\frac{OP}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7BOP%7D%7BRT%7D)
= ![\frac{12}{3.6}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B3.6%7D)
= ![\frac{10}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B3%7D)
b). Since ΔOPQ ~ ΔRTS, their corresponding sides will be proportional.
![\frac{OQ}{RS}=\frac{OP}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7BOQ%7D%7BRS%7D%3D%5Cfrac%7BOP%7D%7BRT%7D)
![\frac{OQ}{4.5}=\frac{10}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BOQ%7D%7B4.5%7D%3D%5Cfrac%7B10%7D%7B3%7D)
OQ = ![\frac{10\times 4.5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5Ctimes%204.5%7D%7B3%7D)
OQ = 15 cm
c). m∠P = m∠T = 60°
d). m∠Q = m∠S
By applying angle sum theorem in ΔRST,
m∠R + m∠S + m∠T = 180°
26° + m∠S + 60° = 180°
m∠S = 180° - 86°
= 94°
Therefore, m∠Q = m∠S = 94°
