Answer:
<h2>
m = ¹/₁₄</h2>
Step-by-step explanation:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y = -14x - 1 ⇒ m₁ = -14
-14×m₂ = -1 ⇒ m₂ = ¹/₁₄
So, the slope of a line perpendicular to the line y = -14x - 1 is m = ¹/₁₄
If the car is traveling at 50meters per second then you need to multiply 50 by 60 to get how many meters a minute then multiply that number by 60 to get meters per hour then take that number and divide it by 1000 to get kilometers per hour.
Answer:360 kilometers in 2 hours and the car is going 180 kilometers per hour
Answer:
a and b
Step-by-step explanation:
Answer:
last week = 150 minutes
this week = 162 minutes
changes = 162-150
= 12 minutes
percentage of changes = (12/150) × 100
= 8%
Answer:
64 square inches
Step-by-step explanation:
You can split this figure into a rectangle and triangle to find the area.
A= l * w
A= 5 * 12
Area of the rectangle = 60 sq in
A= 1/2 bh
b= 12-8 = 4
h= 7-5 =2
A= 1/2 (4)(2)
Area of the triangle = 4 sq in
60 + 4 = 64 sq in
