Answer:
see explanation
Step-by-step explanation:
For the equation to have solutions , then
- 1 ≤ cosq ≤ 1
Since cosq = 1.4 ( out with limits )
Then the equation has no solutions
Are you looking for y and if so y=80
To compare the displayed Wright flyer in the museum with the actual plane, we have to compute for the ratio of the corresponding parameter. In this item, for both the display and the actual plane, we are given with the length. Computing for the ratio gives us,
ratio = length of the model / length of the actual plane
Length of the model = 35 cm
We need to calculate for the length of the model in ft.
length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
length of the model = 1.148 ft
Going back to the equation for the ratio,
ratio = (1.148 ft)/21 ft
ratio = 0.055
Hence, the dimensions used in the model is equal to 0.055 times the actual dimensions.
Error may occur because of the number of significant figures considered for rounding up or down of the answers after each calculation.
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 5 = - 3(x + 2) ← is in point- slope form
with slope m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 
and (a, b) = (6, - 1), hence
y - (- 1) = (x - 6), that is
y + 1 = (x - 6) → C
