A right rectangular pyramid is sliced vertically (down) at the red line by a plane not passing through the vertex of the pyramid
crimeas [40]

The cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a <u>rectangle</u>. Hence, <u>4th option</u> is the right choice.

If the peak of the rectangular pyramid is directly above the center of the base, it creates a perpendicular to the base, indicating the height of the pyramid. This type of rectangular pyramid is known as the right rectangular pyramid.

A rectangle is a quadrilateral, that is a closed figure with 4 line segments, with all four interior angles at 90°.

When we slice a right rectangular pyramid vertically down at the red line by a plane, not passing through the vertex, of the pyramid will be a dilated image of its base.

A dilated image is an enlarged or diminished image of the preimage, similar with all angles.

Thus, the cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a <u>rectangle</u>. Hence, <u>4th option</u> is the right choice.

If the area of a circle is
ozzi

Answer:

Since area =7.7

area =  \frac{22}{7}  {(r)}^{2}  \\  {(r)}^{2}  = 2.45 \\ r = 1.57

Then the circumference is

c = 2pi\times r \\  = 2 \times 3.14 \times 1.57 \\  = 9.859

Graph g(x), where f(x)=2x-5 and g(x)=f(x+1)
tigry1 [53]

Answer:

Graph g(x) = 2x - 3

Step-by-step explanation:

Plug in (x+1) to f(x) = 2x - 5:

g(x) = 2(x+1) - 5 = 2x + 2 - 5

g(x) = 2x - 3

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.
Eva8 [605]

Answer:

100.3 square units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of circle

Note: 2 semicircles = 1 full circle

Area of the figure = a*h + πr²

Where,

a = 10

h = 5

r = ½ of 8 = 4

Plug in the value into the equation

Area = 10*5 + π*4²

Area = 50 + π*16

Area = 100.265482 ≈ 100.3 square units (nearest tenth)
