y + 7 = -5(x - 4)
y + 7 = -5x + 20
y = -5x + 13
Answer: acute
Step-by-step explanation: it is less than 90 degrees so it is less the right angle
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
Step-by-step explanation:
given, f=0.445 Kg
m=?
a=75 N
f=m x a
75=0.445 x m
75/0.445=x
168 Kg =m
Answer:
The elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Step-by-step explanation:
Let's assume the elevation above the sea level is on a number line, then we have to arrange the given number from lowest to highest. These are the numbers in ascending order.
–42ft, –20ft, –18ft, –8ft.
From here we see that, the elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
