Answer:

Option (D)

Step-by-step explanation:

Surface area of a square pyramid is determined from the formula,

Surface area = Area of the square base + 4(Area of one lateral triangular side)

Area of the base = (Side)²

= 8²

= 64 cm²

Area of one lateral triangle = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(8)(8)$

= 32 cm²

Therefore, surface area of the square pyramid = 64 + 4(32)

= 64 + 128

= 192 cm²

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

A bicyclist heads east at 10km/h. After she has traveled 24.2 kilometers, another cyclist sets out in the same direction going 3

Alona [7]

We know that the first cyclist has traveled 24.2 km at a speed of 10 km/h. Lets use the equation $time= \frac{distance}{speed}$ to find the time of the first cyclist:
$t= \frac{24.2}{10}$
$t=2.42$
So, we know that she has traveled for 2.42 hours.

We also know that after she has traveled for 2.42 hours another cyclist sets out in the same direction, so if $t$ represents the time of our first cyclist, the time of our second cyclist will be $t-2.42$ .

Now we are going to use the equation $distance=(speed)(time)$ to relate the speeds and times of the two cyclist:
For the first one:
$distance=10t$ equation (1)
For the second one:
$distance=30(t-2.42)$ equation (2)

Replace (1) in (2)
$10t=30(t-2.42)$
The only thing left now is solve for $t$ :
$10t=30t-72.6$
$-20t=-72.6$
$t= \frac{-72.6}{-20}$
$t=3.63$

We can conclude that the second cyclist will catch up the first cyclist after 3.63 hours.

If f(x) = 8 -3 and g(x) = 3x2 + x-6, find (f + g)(x).

Marizza181 [45]

Answer:

Step-by-step explanation:

(f+g)(x) basically means to "ADD" f(x) and g(x).

We have

$f(x)=\frac{x}{2}-3$
