Answer:
angle of depression = -12 degrees
Step-by-step explanation:
Sin = opposite/hypotenuse
sin = -208/1000
inv sin 0.208 = -12
Answer:
1.26 m cubed
Step-by-step explanation:
1.4*.5*1.8= 1.26
Answer:
16
Step-by-step explanation:
x² + 8x = 4 ⇔ x² + 8x + 16 = 4 + 16 ⇔ x² + 2×4x + 4² = 20 ⇔ (x + 4)² = (2√5)²
Remark : (2√5)² = 20
Slope:

Slope is rise over run. It is a ratio of the amount of the y-axis over the amount of x-axis. So, now assign the first group of numbers, (-2,-3) as 1; then the second group, (1,1) as 2. Like this:

Notice the subscripted numbers designate the group number. Next, plug in the numbers and do the math.

So, the slope, m, is equal to four thirds.
m = 4/3
