Answer:
y - 2 = - 4(x + 2)
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
Here m = - 4 and (a, b) = (- 2, 2 ) , then
y - 2 = - 4(x - (- 2) ) , that is
y - 2 = - 4(x + 2)
Answer:
50.29 cm²
Step-by-step explanation:
Base area of a cylinder = πr²
π = 22/7
r = radius
For circular objects, the width is the same as the diameter of the object
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 8/2 = 4cm
Base area = (22/7) x 4² = 50.29 cm²
Please take a picture or describe the diagram. This is not enough information. Also area is measured in square feet.
As per the problem
A jet flew for 2 hrs before strong head winds reduced its speed by 40 mph.
It took the plane 5 hrs to travel 1,380 miles
Total time=5 hrs, Time of fly before headwinds
,
Time of fly in headwinds
Let the speed before head winds 
Then speed in headwinds
As we know that
Hence using this formula and the given data we can write
Hence speed before flying into the headwinds=300mph
