Answer:

a. π(92)(9) − 1 over 3π(92)(9)

Step-by-step explanation:

Solution given: For A

height =9units

breadth =9units

for both cylinder and cone

Volume of container A=volume of cylinder -volume of cone

=πr²h-1/3×πr²h=π(9²)9-1/3×(9²)9

so your final answer is A

a. π(92)(9) − 1 over 3π(92)(9)

The volume of the container A and container B will be π(9²)9 – (1/3)π (9²)h. Then the correct option is A.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Container A is a cylinder with a radius of 9 units and a height of 9 units. A right cone has been carved from its base and has a height of 9 units.

Then the volume of the container A will be given as

Volume of A = Volume of cylinder – volume of cone

Volume of A = πr²h – (1/3)πr²h

Volume of A = π(9²)9 – (1/3)π (9²)h

Volume of A = (2/3) π(9)³

Container B has the same radius as container A.

Volume of B = (4/6) πr³

Volume of B = (2/3) π(9)³

Then the correct option is A.

Answer:

s = 11.97

Step-by-step explanation:

Answer:

Cuando tenemos un binomio como:

(a + b)^2

El desarrollo es:

a^2 + 2*a*b + b^2

Si en cambio, el binomio es de la forma:

(a - b)^2

El desarrollo es:

a^2 - 2*a*b + b^2

Ahora simplemente usemos esas formulas en cada caso:

a) (2 + 5√)^2

(hay una raiz cuadrada ahi que no aplica a nada, asi que supongo que es un error de tipeo)

entonces tenemos que expandir:

(2 + 5)^2 = 2^2 + 2*(2)*(5) + 5^2 = 4 + 20 + 25 = 49

b) (√3 − √5)^2  

= (√3)^2 - 2*(√3)*(√5) + (√5)^2

= 3 - 2*√(3*5) + 5

= 3 - 2*√15 + 5

= 8 - 2*√15

c) (√( + 3) − √( − 3))^2

Acá hago el reemplazo:

√(-3) = i*√3

Recordar que i^2 = -1

Entonces tendremos:

(√( + 3) − √( − 3))^2 =  (√(  3) − i√( 3))^2

= (√3)^2 - 2*i* (√3)(√3) + (i* (√3))^2

=   3 - 2*3*i  + (i^2*3)

= 3 - 6*i - 3

= - 6i

Answer:

5.6x+5.95-2.4k if that's what you need

Answer:

£1,725.00

Step-by-step explanation:

To calculate simple interest, we use the formula:

a = p(1 + rt)

a is the answer

p is the principle, or the starting amount of money

r is the rate, or the rate of interest (the percent)

and t is the time, or years.

First, 3% as a decimal is 0.03

So we can plug that in as r.

Then just plug the rest of the numbers in.

a = 1500(1 + 0.03 x 2)

Then just solve the equation to get 1,725.00.

Answer:

Step-by-step explanation:

[tex]8(k+3)=12k-4k[/tex]

Distribute the 8

[tex]8k+24=12k-4k[/tex]

Combine like-terms on right side

[tex]8k+24=8k[/tex]

This equation is not true because for any value for k, this equation will never be true. For example, if we subtract 8k from both sides, we get

[tex]24=0[/tex]

Austen needs to buy a bathroom mirror that is 2 feet wide and 3 feet long. If the mirror sells for $5.00 per square foot, what will the total cost of the mirror be?

Substituting the values given in the 1st formula, We get,

⇒ Area of mirror = ( 3 × 2 ) ft²

⇒ Area of mirror = 6 ft²

Substituting the values calculated above in the 2nd formula, We get

⇒ Total Cost of mirror = $ ( 6 × 5.00 )

⇒ Total Cost of mirror = $30

Answer:

  10% loss

Step-by-step explanation:

If Tenzing sold the first watch at 20% profit, his cost c can be found from ...

  1200 = 1.20c

  1000 = c

If Tenzing sold both watches together for 1200 +1350 = 2550, then his total cost can be found from ...

  2550 = 1.02t

  t = 2550/1.02 = 2500

Then his cost for the second watch was ...

  2500 -1000 = 1500

The sale price of 1350 for that watch represents a multiplier m on the watch cost of ...

  1500m = 1350

  m = 1350/1500 = 0.90 = 1 - 0.10

Tenzing lost 10% of its cost on the second watch.

Given:

The date set is:

0,5,6,7,8,13

To find:

The outliers for the given data set.

Solution:

We have,

0,5,6,7,8,13

Divide the data in two equal parts.

(0,5,6),(7,8,13)

Divide each parenthesis in two equal parts.

(0),5,(6),(7),8,(13)

Here, first quartile is [tex]Q_1=5[/tex] and the third quartile is [tex]Q_3=8[/tex].

The interquartile range (IQR) is:

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=8-5[/tex]

[tex]IQR=3[/tex]

The data lie outside the range [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex] is called outliers.

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-1.5(3),8+1.5(3)][/tex]

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-4.5,8+4.5][/tex]

[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[0.5,12.5][/tex]

The data values 0 and 13 lie outside the range [0.5,12.5].

Therefore, 0 and 13 are outliers of the given data set.

[tex]cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)[/tex]

* divide each side by cos ( 55 ) *

[tex]\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055[/tex]

we're left with x = 97.63302055

Answer:

Step-by-step explanation:

A = 40* (365/5)= 29.2%

B = 50*(365/12) = 15.2%

C= 80*(365/15)=19.46%

D = 100*(365/20)=18.25%

so best is B,  then D , then C then A .  

B,D,C,A   in lowest to highest APR

As per the given data, with a base of $400 for loan amount, the ranking of all the given companies from the lowest to highest annual percentage rate is B,D,C, and A.

Annual borrowing costs, including fees, are stated as a percentage and are known as the annual percentage rate, or APR. The APR is a more comprehensive indicator of how much borrowing money will cost because it includes both interest rates and application fees.

Instead of just a monthly fee or rate, the term annual percentage rate of charge refers to the interest rate for the entire year as applied to a loan, home loan, credit card, and many more. It can also be referred to as a nominal APR or an effective APR. It is a financial fee that is calculated at an annual rate.

Required calculations are as follow:

A = 40 × (365/5)= 29.2%

B = 50 × (365/12) = 15.2%

C= 80 × (365/15)=19.46%

D = 100 × (365/20)=18.25%

Therefore, the ranking of all the companies  with the lowest to highest annual percentage rate are B,D,C, and A.

Answer: Step-by-step explanation:

f(x)=ax^2→g(x)=a(x-h)^2+k

The horizontal shift depends on the value of h. The horizontal shift is described as:  

g(x)=f(x+h) - The graph is shifted to the left h units.

g(x)=f(x−h) - The graph is shifted to the right h units.

Hence, in the question above, Horizontal Shift: Right h Units

The vertical shift depends on the value of k. The vertical shift is described as:

g(x)=f(x)+k - The graph is shifted up k units.

g(x)=f(x)−k - The graph is shifted down k units.

Therefore, in the question above, Vertical Shift: Up k Units

The description of the transformation from the graph with respect to the given graph should be explained below.

Since

[tex]f(x)=ax^2[/tex]

And, [tex]g(x)=a(x-h)^2+k[/tex]

Now here horizontal shift based on the value of h. The horizontal shift should be like

g(x)=f(x+h) - The graph should be shifted to the left h units.

And,

g(x)=f(x−h) - The graph should be shifted to the right h units.
