Answer:

360mm^2

Step-by-step explanation:

Surface area of a square pyramid= Base area + Lateral area

Base area=10mm × 10mm

=100mm^2

Lateral area = (4) × (1/2) × (10) × √(12) ^ 2 + (5) ^ 2)

= 260 mm^2

Surface area= Base area + Lateral area

=100mm^2 + 260mm^2

= 360mm^2

F(x)=∣x∣
elixir [45]

Answer:

Step-by-step explanation:

There are two transformations, one vertical, one horizontal.

The + 9 part outside the absolute value sign moves the graph up 9 units.

Replacing  x  with  x - 1 moves the graph right 1 unit.

<em>Comment:</em>  The horizontal shifts sometimes appear backwards:  x - 1 looks like a shift to the left, but it's not.

Example:  f(4) = |4| = 4.  To get the same output (4) from g(x), you have to use a value for  x  that is 1 unit <u>larger</u> than 4.  g(5) = |5 - 1| = 4.

Assuming you meant is - \frac{3}{5} x+ \frac{1}{5} \ \textgreater \  720

The answer would be :
- \frac{3}{5} x\ \textgreater \ 719.8

x \ \textless \  \frac{719.8}{ \frac{-3}{5} }
x\ \textless \  719.8 *( \frac{-5}{3} )
x\ \textless \  \frac{-3599}{3}

Hope this helps !
