Answer:

Step-by-step explanation:

surface area=top circle+bottom circle+straight face

top circle=bottom circle=pi(w-1)^2

straight face=length*height=circle circumference*height

=2pi(w-1)(w+3)

surface area=2pi(w-1)^2+2pi(w-1)(w+3)

=2pi(w-1)(w-1+w+3)

=2pi(w-1)(2w+2)

=4pi(w-1)(w+1)

Answer:

4π(w+1)(w-1)

Step-by-step explanation:

The total surface area of the cylinder

= 2 x area of base circle + area of vertical surface

= 2x pi x radius^2 + 2x pi x radius x height

= 2π(w-1)^2 + 2π(w-1)(w+3)

= 2π[w^2-2w+1 + w^2+2w-3]

= 2π(2w^2-2)

= 4π(w^2 - 1)

= 4π(w+1)(w-1)

Is dollars 250 is to be divided among Neymar Rohit Sharma and Nadal so that Neymar gets two parts Rohit gets three parts and Nad
Hatshy [7]

Answer:

Step-by-step explanation:

Total amount of money to be shared among Neymar, Rohit Sharma and Nadal is $250

Neymar gets two parts. This means that Neymar gets 1/2 × total amount of money.

Neymar gets 1/2 × 250 = 125

The percentage will be amount that Neymar gets divided by the total amount and multiplied by 100. It becomes

125/250 × 100 = 50%

Rohit gets three parts. This means that Rohit gets 1/3 × total amount of money.

Rohit gets 1/3 × 250 = 83.33

The percentage will be amount that Rohit gets divided by the total amount and multiplied by 100. It becomes

83.33/250 × 100 = 33.33%

Nadal gets five parts. This means that Nadal gets 1/5 × total amount of money.

Nadal gets 1/5 × 250 = 50

The percentage will be amount that Nadal gets divided by the total amount and multiplied by 100. It becomes

50/250 × 100 = 20%

Fill in the blank spaces please.
Kisachek [45]

<u><em>PART A</em></u>

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

<u>So for 2 pounds, it would cost </u><u>$5.00</u>

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

<u>For the 1 pound one, it would cost </u><u>$2.50</u>

<u></u>

<u><em>PART B</em></u>

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, <u>$1 = 0.4lb</u>

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x <u>$9 = 3.6lb</u>

<u></u>

Which of the following vectors are orthogonal to (1,5)? Check all that apply
Andre45 [30]
We know that
If the scalar product of two vectors<span> is zero, both vectors are </span><span>orthogonal

</span><span>A. (-2,5)
</span>(-2,5)*(1,5)-------> -2*1+5*5=23-----------> <span>are not orthogonal 

</span><span>B. (10,-2)
</span>(10,-2)*(1,5)-------> 10*1-2*5=0-----------> are  orthogonal 

<span>C. (-1,-5)
</span>(-1,-5)*(1,5)-------> -1*1-5*5=-26-----------> are not orthogonal 

<span>D. (-5,1)
</span>(-5,1)*(1,5)-------> -5*1+1*5=0-----------> are  orthogonal 

the answer is 
B. (10,-2) and D. (-5,1)  are  orthogonal  to  (1,5)
