Answer:
<u>274 square units</u>
Step-by-step explanation:
<u>Surface Area of the prism</u>
- SA = 2(base x height) + 2(length x height) + 2(base x length)
- SA = 2(bh + lh + bl)
<u>Here</u> :
- b = 4
- h = 5
- l = 13
<u>Solving</u>
- SA = 2(4 x 5 + 13 x 5 + 4 x 13)
- SA = 2(20 + 65 + 52)
- SA = 2(137)
- SA = <u>274 square units</u>
Answer:
-p^4 + 4p^3 - 5p^2 + 8p - 6
Step-by-step explanation:
Distribute the -p^2 to the p^2 and the 2. Then distribute the 4p to the p^2 and the 2. Then distribute the -3 to the p^2 and the 2.
When we expand:
-p^4 - 2p^2
+ 4p^3 + 8p
-3p^2 - 6
Group, ordering from highest to lowest "degree" (exponent).
-p^4 + 4p^3 - 2p^2 - 3p^2 + 8p - 6
Combine like terms.
-p^4 + 4p^3 - 5p^2 + 8p - 6
<u>E</u><u>x</u><u>p</u><u>l</u><u>a</u><u>n</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u>
<u>Formula to be used,</u>
- 1st equation of motion, <u>v = u + at</u>
- • 3rd equation of motion,<u>v² - u² = 2</u> as
<u>Solution,</u>
Putting all the values, we get
<u>v=u + at</u>
⇒0 = u + (-0.5) × 20
⇒-u=-0.5 × 20
<u>⇒u = 10 m/s</u>
<u>Hence, the initial vel</u><u>ò</u><u>city of the car is 10</u>
<u>city of the car is 10m/s.</u>
Now, the distance covered,
<u>v²-u² = = 2as</u>
⇒ (0)²-(10)² = 2 × (-0.5) × s
⇒-100 = - 1s
<u>⇒ s = 100 m</u>
<u>Hence, the distance covered is 100 m.</u>
