Area of the base=
5×12=60 square inches.
Area of two triangles=
4.3×5=21.5 square inches
Area of the other two sides=
5×12×2=120 square inches.

60+21.5+120=201.5 square inches is your final answer. Hope it help!

To approach the runway, a pilot of a small plane must begin a 10° descent starting from a height of 1983 feet above the ground.

The plane must be 3.38 miles away from the runway to begin the descent. The equation I used was "y = -0.1111111x + 0.3755682", 0.37~ being the height in feet (in miles) and -0.11~ being the descent. The x-intercept is located at 3.38.

Hey guys please help me and try to show ur work

This is the net of a rectangular prism, so the surface area can be found with the formula: SA=2lw+2wh+2lh

In this case,

l=10.5
w=6.4
h=4

Now, we can plug these numbers into the equation:

SA= (2)(10.5)(6.4) + (2)(6.4)(4) + (2)(10.5)(4)
SA= 134.4 + 51.2 + 84
SA = 269.6 cm

Therefore, the answer is D.

Approximate the area under the

AlekseyPX

Answer:

67 square units

Step-by-step explanation:

The area using the left-hand sum is the sum of products of the function value at the left side of the interval and the width of the interval.

The attachment shows a table of the x-value at the left side of each interval, and the corresponding function value there. The interval width is 1 unit in every case, so the desired area is simply the sum of the function values.

The approximate area is 67 square units.
