Answer:
option (d) is correct.
if a line crosses the y-axis at (0, 1) and has a slope of , then equation of line is 5y - 4x = 5.
Step-by-step explanation:
Given : if a line crosses the y-axis at (0, 1) and has a slope of .
We need to find the equation of line.
Equation of line is of the form y = mx + c, where m is the slope of line and c is the y- intercept. that is the point where line meets y- axis.
Given y intercept at (0, 1 ) ⇒ c = 1
Also, slope m =
Substitute it in equation, we get ,
y = mx + c ⇒
Solving , we get equation of line as ,
5y = 4x + 5 ⇒ 5y - 4x = 5
Thus, option (d) is correct.
if a line crosses the y-axis at (0, 1) and has a slope of , then equation of line is 5y - 4x = 5.
Answer:
12.8 m
Step-by-step explanation:
From the diagram :
Height PR = 19m
Using Pythagoras :
From triangle PQR:
QR = x
Tan θ = opposite / Adjacent
Tan 22° = x / 19
x = tan 22° * 19
x = 0.4040262 * 19
x = 7.6764982 m
From triangle PRS:
SR = y
Tan θ = opposite / Adjacent
Tan 15° = y / 19
y = tan 15° * 19
y = 0.2679491 * 19
y = 5.0910346
Height of entire screen :
(7.6764982 + 5.0910346) m
= 12.7675328 m
= 12.8 m
