Answer:

Step-by-step explanation:

CD=√((-1-3)²+(2+2)²)=√(16+16)=√32=4√2

Altitude EF=√((0-2)²+(1-3)²)

=√(4+4)=√8=2√2

area=1/2 ×4√2×2√2=8 square units

The coordinates of point Lon a coordinate grid are (-2,-4) Point L is reflected across the y-axis to obtain point M and across t
aivan3 [116]

Answer:

Point M = (2, -4)

Point N = (2, 4)

Step-by-step explanation:

Point L = (-2,-4)

If it is reflected over y-axis, it's y-coordinate remains the same and x-coordinate will change into it's opposite.

Point M = (2, -4)

The, it is reflected over x-axis, it's x-coordinate remains the same and y-coordinate will change into it's opposite.

Point N = (2, 4)

Estimate the time it would take you to drive 361 miles at 42 miles per hour. Round to the nearest hour.
polet [3.4K]

Answer:

It would take you 9 hours

Step-by-step explanation:

Speed (s) = Distance (d) / Time (t)

given that; Speed = 42 miles/hour

                 Distance = 361 miles

42 miles/hour = 361 miles / Time (t)

Time (t) * 42 miles/hour = 361 miles

Time (t) = 361 miles / 42 miles/hour

Time (t) = 8.59 hours

             ≈ 9 hours (to the nearest hour)

Write an exponetial function for the points (1,7.5) (3,16.875) in the form y=a•b^x
Anna11 [10]
16.875=ab^3  (divided by what follows)

7.5=ab^1  gives you:

2.25=b^2

b=1.5 now we can solve for a...

7.5=a(1.5^1), a=5 so the function is:

y=5(1.5^x)
