The number in the ten thousands place is 7
Look at the number in the place value next to it. It is a 5. Note that numbers 5 and greater round up, while 4 and lower round down.
103,080,000 is your answer
hope this helps
Answer:
6
Step-by-step explanation:
Slope of AB
m = (y2 - y1)/(x2 - x1)
m = (11 - (-4))/(2 - (-1))
m = (11 + 4)/(2 + 1)
m = 15/3
m = 5
The slope of line AB is 5
Slope of CD
m = (y2 - y1)/(x2 - x1)
m = (10 - 1)/(4 - 1)
m = 9/3
m = 3
The slope of CD is 3
Since the two slopes are not equal, this means the lines are not parallel.
Since (slope of AB)*(slope of CD) = 5*3 = 15 is not equal to -1, this means the lines are not perpendicular
Answer: Neither (not parallel; not perpendicular)
Answer:
c) 60°
Step-by-step explanation:
We solve this question using trigonometric function of Cosine.
cos θ = Adjacent/Hypotenuse
θ = ???
Adjacent = Base of the ladder is on the ground = 2.5 feet
Hypotenuse = Length of the ladder = 5 feet
cos θ = 2.5/5
θ = arc cos (2.5/5)
θ = 60°
Therefore, the measure of the angle created by the ladder and the ground is 60°
X=line straight across y=vertical line
