Answer:

the total surface area is 40 + 12 + 15 = 67 square units

Step-by-step explanation:

Refer to the diagram:

the combined area of the top and bottom is 2(5·4) = 40:

the combined area of the ends is 2(1.5·4) = 12; and

the combined area of the front and back is 2( 5 · 1.5) = 15

and so the total surface area is 40 + 12 + 15 = 67 square units

A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet awa

tatuchka [14]

Answer:

Second puck travels farther

Step-by-step explanation:

Maximum height of first puck = 3 feet

The height of a second hockey puck is modeled by:

$y=x\left(0.15-0.001x\right)$

$y=0.15x-0.001x^2$

To find maximum height of second puck

$y'=0.15-0.002x$

Equate the derivative equals to 0

0.15-0.002x=0

$\frac{0.15}{0.002}=x$

75 = x

At x = 75

$y=0.15(75)-0.001(75)^2=5.625$

So, The maximum height of second puck is greater than first puck

So, Second puck travels farther

Find the total surface area of the following square pyramid: 9 cm 10 cm SA = [?]cm2

MakcuM [25]

Answer:

280 cm2

Step-by-step explanation:

1)find the area of square

A=LW

=10×10

=100

2) find the area of triangle

A=B×H÷2

=10×9/2

=45

Coz,there are 4 triangle we multiple by 4

=45×4

=180

3)find the total surface area by adding the two

=100+180

=280cm2
