Answer:

Volume = [tex]\frac{64}{3}[/tex]

Step-by-step explanation:

Given - Consider the solid S described below. The base of S is the triangular region with vertices (0, 0), (4, 0), and (0, 4). Cross-sections perpendicular to the x-axis are squares.

To find - Find the volume V of this solid.

Solution -

Given that,

The equation of the line with both x-intercept and y-intercept as 4 is -

[tex]\frac{x}{4} + \frac{y}{4} = 1[/tex]

⇒x + y = 4

⇒y = 4 - x

Now,

Volume = [tex]\int\limits^a_b {A(x)} \, dx[/tex]

where

A(x) is the area of general cross-section.

It is given that,

Cross-sections perpendicular to the x-axis are squares.

So,

A(x) = (4 - x)²

As solid lies between x = 0 and x = 4

So,

The Volume becomes

Volume = [tex]\int\limits^4_0 {(4 - x)^{2} } \, dx[/tex]

             = [tex]\int\limits^4_0 {[(4)^{2} + (x)^{2} - 8x] } \, dx[/tex]

             = [tex]\int\limits^4_0 {[16 + x^{2} - 8x] } \, dx[/tex]

             = [tex]{[16 x + \frac{x^{3}}{3} - \frac{8x^{2} }{2} ] } ^4_0[/tex]

             = [tex]{[16(4 - 0) + \frac{4^{3}}{3} - \frac{0^{3}}{3} - 4 [4^{2} - 0^{2}] ] }[/tex]

             = [tex]{[16(4) + \frac{64}{3} - 0 - 4 [16 - 0] ] }[/tex]

             = [tex]{[64 + \frac{64}{3} - 64 ] }[/tex]

             = [tex]\frac{64}{3}[/tex]

⇒Volume = [tex]\frac{64}{3}[/tex]

Answer:

  B, D

Step-by-step explanation:

The quadratic expands to ...

  (2n -1)² = (2n)² +2(2n)(-1) +(-1)² = 4n² -4n +1

The coefficients can be factored out of the sum, so ...

  ∑(4n²) = 4∑n² for example

The sum of 60 ones is 60:

  [tex]\displaystyle\sum_{n=1}^{60}{1}=1+1+1+\dots+1=60[/tex]

So, the sum can be written as ...

  [tex]\displaystyle\sum_{n=1}^{60}{(2n-1)^2}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+\sum_{n=1}^{60}{1}}\\\\=\boxed{4\sum_{n=1}^{60}{n^2}-4\sum_{n=1}^{60}{n}+60}[/tex]

Answer:

18 nickels, 9 dimes, 6 quarters.

Step-by-step explanation:

Basically, I just made a money table and used it to get my equation, which is: 60x-30=330, to get how many quarters there are. Then, plug that in to the problem and you have your answer.

let h=-12, k=-11 then

(x-h)^2 + (y-k)^2= r^2

(x+12)^2 + (y+11)^2 = 7^2

x^2 + 24x + 144 + y^2 + 22y + 121 = 49

x^2 + y^2 + 24x + 22y + 144+121-49= 0

x^2 + y^2 + 24x + 22y + 216 = 0 is the required eq

Answer:

C. The rudely disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the politely disagrees condition has a mean of 3.82 and standard deviation of 0.97

Step-by-step explanation:

The given data is  

                                          x`             Std. Dev      

R. disagrees                  4.16       0.854        

P. disagrees                 3.82       0.967        

From this data we see that the R. disagrees has a mean of 4.16 and standard deviation of 0.854

while

the P. disagrees has a mean of 3.82 and standard deviation of 0.967.

Same figures are given only in option C because

Rounding 0.854 gives 0.85

Rounding 0.967 gives 0.97

So only option C is the best choice.

C. The R. Disagrees condition has a mean of 4.16 and a standard deviation of 0.85 while the P. Disagrees condition has a mean of 3.82 and standard deviation of 0.97

Answer:

14.4 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Hypothenus = 36 m

Height of building (H) = 33 m

Length of shadow (L) =?

The length of the shadow can be obtained as follow:

Hypothenus² = H² + L²

36² = 33² + L²

1296 = 1089 + L²

Collect like terms

1296 – 1089 = L²

207 = L²

Take the square root of both side

L = √207

L = 14.4 m

Therefore, the length of the shadow is 14.4 m

Answer:

50%

Step-by-step explanation:

Each die roll (is presumably) independent from the last

this means that rolling an even in the first roll does not effect the odds of getting another even in the next

therefore the odds of getting an odd in the next role is simply 1/2

The probability that your next roll will be an odd number is 50%.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of samples

Given that you are rolling a die and you have rolled for the last 10 times an even number.

Each die roll (is presumably) independent from the last. This means that rolling an even in the first roll does not affect the odds of getting another even in the next

Therefore the odds of getting odd in the next role is simply 1/2.

Answer:

Step-by-step explanation:

Answer:

E and F

Step-by-step explanation:

So, our inequalityis that the square root of x is eithr greater than or equal to 25.

Lets think of this as a equation, and try solving for x:

[tex]\sqrt{x} \geq 25[/tex]

Lets square both sides to get x normal:

[tex]x\geq 625[/tex]

Now, x must either be greater than or equal to this value.

Lets look at the answers:

125

-625

-5

5

700

625

Well, most these answers are below the 625.

However, some of these values look like they may be right:

-625

700

625

So, -625 cannot be it. Although it seems to be equal to to 625 above, its negative. This means its much smaller than it

We also have 625 and 700

700 is greater than 625, so that has to be an answer.

Remember that its greater than or equal to.

625 is equal to 625, so this is an answer as well.

Answers:

625 and 700

Answer: 6.67 feet (check to see if you made a typo)

Step-by-step explanation:

if the scale factor is ten than we multiply 8 by 10

8 * 10 = 80

important to remember this is 80 INCHES not 80 FEET

to convert 80 inches into feet, we divide by 12 because there are 12 inches in a foot

80/12 = 6.67 feet

check to make sure that the first option is actually 6.67 inches because it would make more sense for it to be in feet
