Hector covers each face of the pyramid below

Mathematics
1 answer:
Bad White [126]3 years ago

The image is missing, so i have attached it.

Answer:

area he will cover with paper = 196 in²

Step-by-step explanation:

From the image, we see that the base of the face= 8 inches while the height is 14 inches.

We know area of triangle is;

A = (1/2) x base x height

Thus;

A = (1/2) x 8 x 14 = 55 in²

This is area of one side face.

Thus area of 3 side faces = 56 x 3 = 168 in²

Thus, total area covered is;

Area of side faces + area of base = 168 + 28 = 196 in²

Which linear inequality represents the graph below?
musickatia [10]

Answer:

A.

Step-by-step explanation:

It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not.

(x² +9) and g(x) are factors of f(x).
That is, (x² +9)(g(x)) = f(x).

The roots of (x² +9) are roots of f(x). They are 3i and -3i.

The factor (x² +9) has degree 2, so f(x) has degree at least 2.

We cannot say anything about the x- or y-intercepts based on this information.

Imaginary roots usually come in even numbers (2, 4, etc.) for the polynomials we study. The information given here does not support the idea of 3 imaginary roots for f(x).
