$\huge \boxed{\mathfrak{Question} \downarrow}$

Determine the surface area of the right square pyramid.

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

The formula for finding the surface area of a right square pyramid is ⇨ b² + 2bl, where

b = base of the right square pyramid
l = slant height of the right square pyramid.

In the given figure,

base (b) = 4 ft.
slant height (l) = 8 ft.

Now, let's substitute the values of b & l in the formula & solve it :-

$\sf \: {b}^{2} + 2bl \\ = \sf \: {4}^{2} + 2 \times 4 \times 8 \\ = \sf \: 16 + 8 \times 8 \\ = \sf \: 16 + 64 \\ = \huge\boxed{\boxed{ \bf 80 \: ft ^{2} }}$

So, the surface area of the right square pyramid is 80 ft².

If the half-life of a radioactive substance is 2,800 years, then at what rate is it decaying?

vlada-n [284]

Answer:

0.0001075

Step-by-step explanation:

The relation between halflife and rate at which it is decaying is given by

$t_{\frac{1}{2} } =\dfrac{log2}{rate}$

now in the above problem halflife is given as 2800 years substituting in the above equation we get the value of rate at which it is decaying to be rate=0.0001075.

Ok this is kind of silly to ask but I have an equation 12-3x how do I get 3x in the front

lesantik [10]

As you can see there is a negative sign befor 3x. That means 3x is a negative value. Therefore, in order to place it as first left value you would take -3x and put it before +12 ( since there is no negative sign before 12, it will stay positive)

-3x+12

Hope This Helps :)
