Answer: option a

Step-by-step explanation:

You must apply the formula for calculate the surface area of the prism, which is shown below:

SA=bh+2ls+lb

Where:

b=8 cm

h=3 cm

l=10 cm

s=5 cm

When you susbstitute the values shown above into the formula for calculate the surface area, therefore you obtain:

SA=(8cm*3cm)+2(10cm*5cm)+(10cm*8cm)\\SA=204cm^{2}

Hello there!

Answer:

4. dy/dx = -2

8. dy/dx = 1/2 x^(-3/2)

10/ dy/dr = 4 pi r^2

Step-by-step explanation:

4.  y = -2x+7

dy/dx = -2(1)

dy/dx = -2

8.  y = 4 - x^-1/2

 dy/dx =  - (-1/2x^ (-1/2-1)

 dy/dx = 1/2 x^(-3/2)

10.  y = 4/3 pi r^3

dy/dr = 4/3 pi  (3r^2)

dy/dr = 4 pi r^2
