Answer:
Volume = 1539.38 cm³
Surface Area = 747.7 cm²
Step-by-step explanation:
Volume = πr² h
V = π(7)²(10)
V = π(49)(10)
V = 490π
V = 1539.38 cm³
Surface Area = 2πrh + 2πr²
SA = 2π(7)(10) + 2π(7)²
SA = 2π(70) + 2π(49)
SA = 140π + 98π
SA = 238π
SA = 747.7 cm²
Answer:
Step-by-step explanation:
I'm not sure what some of the ordered pairs are in what you wrote, but a function is when each input has one output. So, for every x there is one y. The x values can not repeat. So, remove one of two ordered pairs where the x value is repeating.
Just solve the quadratic, you need to figure out what value you can use to FOIL and get c^2+5c-24=0. so you need to figure out what values you can add together to get 5 and multiply together to get -24 so try (c+8)(c-3) here 8 and 3 make sense since 8-3 = 5 and 8*-3=-24 so the answer is (c+8)(c-3).
Answer:
5/36
Step-by-step explanation:
So a pair of dice is rolled. 2 dices. A dice has 6 numbers (1,2,3,4,5,6).
Now draw a sample space.
<u> </u><u>1 2 3 4 5 6</u>
<u>1</u> 2 3 4 5 6 7
<u>2</u> 3 4 5 6 7 8
<u>3</u> 4 5 6 7 8 9
<u>4</u> 5 6 7 8 9 10
<u>5</u> 6 7 8 9 10 11
<u>6</u> 7 8 9 10 11 12
It's asking for SUM, so we plus. Thats why you see this.
So look for all the 8's in the sample space. Theres one in (6,2), (5,3), (4,4), (3,5) and (2,6). Thats 5. We divide that with the total. The total is 36 because there are 36 possible values. so 5/36
