Which expression can be used to find the surface area of the following square pyramid?

Mathematics
1 answer:
pantera1 [17]3 years ago
4 0

Answer:

4[1/2(5 x 6)] + 6x6

Step-by-step explanation:

The first part of the expression is <em>4[1/2(5 x 6)].</em> This is the formula to find the surface area of the triangles. A regular triangle's area is <em>1/2(l*w).</em> Since there are four trinagles, you have to multiply the whole expression by 4.

The second part of the equation is finding the surface area of the base which is a square. Since squares have four equal sides, its safe to say that you can use <em>6 * 6.</em>

The graphs below have the same shape. What is the equation of the blue<br> graph?
Tems11 [23]

Answer:

Option (A)

Step-by-step explanation:

Parent function (in red) graph is represented by,

f(x) = x²

If this function is translated by 'a' units to the right, rule to be followed,

f(x) → f(x - a)

If the parent function is shifted by 4 units to the right (blue graph), the new function will be,

g(x) = f(x - 4)

g(x) = (x - 4)²

Therefore, Option (A) will be the correct option.

Which statement about the equation y = 5x – 8 is correct?
lbvjy [14]

9514 1404 393

Answer:

  A. The equation represents a linear function because the equation is in the form y = mx + b

Step-by-step explanation:

A linear function does not have to be in the form y = mx + b, but if a function is in that form, it is a linear function.

  choice A is appropriate

__

A function may have two variables, x and y, and not be a linear function. For example, y = x² is not a linear function. The fact that it has two variables is not what makes it linear.
