Answer:

Explanation:

Given:

Volume of the cone = 4π dm³

diameter of the base = 80cm

To find:

the area of the base

The base of a cone is a circle. Area of the base will be area of the circle

diameter = 80cm

diameter = 2(radius)

radius = diameter/2

radius = 80/2 = 40 cm

We need to convert from cm to dm to get same units

10cm = 1 dm

40cm = 4 dm

let π = 3.14

substitute the values into the formula:

The statement makes sense. This is because A 200 percentage increase in price corresponds to a price that is 300% of the original price

You can express a fraction of something using percentages. A change in something can be described using percentages. As an illustration, the price of milk increased by 5% last month.

By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage.

A figure or ratio stated as a fraction of 100 is called a percentage. The % sign is frequently used to indicate it. In this case, 200% of something implies that it will give 300% of the initial amount.

We have the next formula to the simple interest

where

I= interest earn after t years

P is the initial deposit

r is the rate

t is the time

P=1500

r=2.5%

t= 4 years

then we substitute the values in the formula

Jimmy earned $6840 from the gift basket sold

What is selling price ?

The selling price is how much a buyer pays for a product or service.

Given,

Number per basket for fruits = 12

Total number of fruits shipped last year = 3,420

Per basket price = $24

Now, we have to find total number of baskets

Total number of baskets = 3420 / 12

                                         = 285

Total amount jimmy earned = 285 * 24

                                              = $6840

Therefore, Jimmy earned $6840 from the gift basket sold.

The given functions are f(x) = 9x-2  and g(x)=√(√3x +7) the value of f (3) and g (3) will be 25 and 3.4592.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that  f(x) = 9x-2 and g(x)=√√3x +7.

We obtained that independent variables will have an impact on dependent variables. What occurs as a result of the independent variable is referred to as a dependent variable.

We have to evaluate the values one by one putting the value of an independent variable as,

a) g (3)

g(x)=√(√3x +7)

g(3) = √(√3(3) +7)

g(3) =√(5.196 + 7 )

g(3) =√(12.196)

g(3) =3.492

b)f (3)

f(x) = 9x-2

f(3) = 9× 3 -2

f(3) = 27 - 2

f(3) = 25

Thus, the given functions are f(x) = 9x-2  and g(x)=√(√3x +7) the value of f (3) and g (3) will be 25 and 3.4592.

The value of the function (g•f )(x) is 8x-3.

Given the functions are:

g(x) = 4x+5

f(X) = 2x-2

we are asked to determine (g•f )(x) = ?

⇒ g(x) = 4x+5

⇒ f(x)  = 2x-2

⇒  (g•f )(x), substitute the value for f(x)

⇒ g(f(x))

⇒ g(2x-2)

now put the value g(2x-2) in g(x)

⇒ g(2x-2) = 4x+5

⇒ g(2x-2) = 4(2x-2) + 5

⇒ g(2x-2) = 8x - 8 + 5

⇒ g(2x-2) = 8x - 3

Hence we get the value of  (g•f )(x) as 8x-3

Given matrix A:

[tex]\left[\begin{array}{ccc}5&-15&-44\\-1&2&6\\1&-3&-9\end{array}\right][/tex]

To find the inverse of the matrix we start by finding the determinant of the matrix.

|A| = 5(-18+18) + 15(9-6) - 44(3-2)

= 0 + 15(3) - 44 = 45 - 44 = 1

As the determinant 1 ≠ 0, hence the inverse of the matrix exists.

Now, we find the minors of each element of the matrix.

m₁₁ =  [tex]\left[\begin{array}{ccc}2&6\\-3&-9\end{array}\right][/tex]  = 0

m₁₂= [tex]\left[\begin{array}{ccc}-1&6\\1&-9\end{array}\right][/tex] = 3

m₁₃ =  [tex]\left[\begin{array}{ccc}-1&2\\1&-3\end{array}\right][/tex] = 1

m₂₁ = [tex]\left[\begin{array}{ccc}-15&-44\\-3&-9\end{array}\right][/tex] = 3

m₂₂ = [tex]\left[\begin{array}{ccc}5&-44\\1&-9\end{array}\right][/tex] = -1

m₂₃ = [tex]\left[\begin{array}{ccc}5&-15\\1&-3\end{array}\right][/tex] = 0

m₃₁ = [tex]\left[\begin{array}{ccc}-15&-44\\2&6\end{array}\right][/tex] = -2

m₃₂ = [tex]\left[\begin{array}{ccc}5&-44\\-1&6\end{array}\right][/tex] = -14

m₃₃ = [tex]\left[\begin{array}{ccc}5&-15\\-1&2\end{array}\right][/tex] = -5

The cofactor matrix can be obtained as:

[tex]\left[\begin{array}{ccc}0&3&1\\3&-1&0\\-2&-14&-5\end{array}\right][/tex]

Now the adjoint of matrix A (written as adj A) by taking the transpose of the cofactor matrix of A is,

[tex]\left[\begin{array}{ccc}0&-3&-2\\-3&-1&14\\1&0&-5\end{array}\right][/tex]

To determine the inverse of a square matrix A, we use the formula:

A⁻¹ = adj(A) / |A|

Therefore, the inverse of the given matrix is:

A⁻¹ = 1/1 [tex]\left[\begin{array}{ccc}0&-3&-2\\-3&-1&14\\1&0&-5\end{array}\right][/tex]

It is given, Ax = b

and b = [tex]\left[\begin{array}{ccc}-2\\-2\\-2\end{array}\right][/tex]

Let x be [tex]\left[\begin{array}{ccc}a\\b\\c\end{array}\right][/tex]

Putting values in Ax = b equation,

[tex]\left[\begin{array}{ccc}0&-3&-2\\-3&-1&14\\1&0&-5\end{array}\right]\left[\begin{array}{ccc}a\\b\\c\end{array}\right]=\left[\begin{array}{ccc}-2\\-2\\-2\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}-3b-2c\\-3a-b+14c\\a-5c\end{array}\right]=\left[\begin{array}{ccc}-2\\-2\\-2\end{array}\right][/tex]

Equating the three equations with the respective values,

So, -3b - 2c = -2

-3a -b + 14c = -2

a - 5c = -2 ⇒ a+2/5 = c

Solving the above equations we obtain the values of a,b, and c as 108, -14, and 22.

So, the matrix x is

the expression has a value closest to 1 is √37 - √26 (option C)

Explanation:

To determine the expression, we need to solve each of the options.

a) 7π/√10 = 7(3.14) /√10 = 21.98/3.1623

= 6.95

b) √75 - √74 = 8.66 - 8.60

= 0.06

c) √37 - √26 = 6.083 - 5.099

= 0.984

d) (3√5 - √20)/√2 = (6.708 - 4.472)/1.414 = 2.236/1.414

So that, for 10 gallons

Thus, the tank can hold 37.85 liters of gas.

we have the system of equations

y=3x+4 ----> equation 1

y=ax+b ----> equation 2

Remember that

The only condition for the system, to have only one solution is that the slopes of both lines are different

so

The values for a are all real numbers except for a=3

The values for b are all real numbers

Therefore

A solution could be

Given : A right angled triangle with the below mentioned measures :

angles ∠ 1 = 28 °

∠ 2= 25° and the length is 600

To find : the value of x

Let us assume the rest of the length is y that is the side opposite of the angle will now be x + y

thus tan 28 ° = [tex]\frac{x+y}{600}[/tex]

tan 28 °= 0.53 thus the equation after cross multiplying becomes ;

0.53 × 600 = x + y

318 = x + y ------------------ equation 1

And tan 25° = [tex]\frac{y }{600}[/tex]

tan 25 ° = 0.46  

After cross multiplying we get : 0.46 × 600 = y

=> 276 = y

Substituting this value in equation 1 we get : 318 = x + 276

The inner core is solid because the inner core consists of a lot of pressure and high temperatures. This is true.

The pressure surrounding the inner core, as well as the planet's atmosphere, keeps the iron from melting. The iron atoms cannot migrate into a liquid form due to the pressure and density, which are simply too high.

Temperature is a measure of how hot or cold something is, more particularly the average kinetic energy of the particles in an object, which is a sort of energy related with motion. Temperature is a measure of how hot or cold something is represented in terms of one of several scales, including Fahrenheit and Celsius.

Because the inner core is under intense pressure and is extremely hot, it is solid. And the stuff becomes denser as pressure and temperature increase. Therefore, the inner core's high heat and pressure are what are solidifying it since the denser the stuff is, the more solidified it becomes.
