In a course of 12 weeks, Perry will be able to play a total of 25 pieces of the piano Leon.

A total of 18 pieces of piano are learnt by Perry in a course of 9 weeks.

By using simple algebra, we can find the number of pieces that will be played by Perry in one week,

So, we can write, The learing speed,

Number of piano pieces learnt = Weeks

19 pieces = 9 weeks

Learning speed = 19/9 Pieces per week

So, the number of pieces learnt in 12 weeks is,

Number of pieces learnt = 19/9 x 12

Number of pieces learnt = 25.22

Number of pieces learnt = 25

So, Perry will be able to play 25 pieces.

[tex]\pi \times r = 3.14 \times 5 = 15.7[/tex]

Answer:

141.6925 [tex]ft^{2}[/tex]

Step-by-step explanation:

Area of rectangle  = LW

A = 29 x 19 = 551 [tex]ft^{2}[/tex]

Semicircle = [tex]\frac{\pi r^{2} }{2}[/tex]

[tex]\pi[/tex] = 3.14

r = 19/2 = 9.5

[tex]\frac{(3.14)(9.5^{2}) }{2}[/tex]

(9.5)^2 = 90.25

3.14 x 90.25 = 283.385

283.385/2 = 141.6925 [tex]ft^{2}[/tex]

Answer:

Step-by-step explanation:

We have, C(x) = 0.005x3 – 0.02x2 + 30x + 5000

Clearly, the marginal cost, MC (x) = \(\frac{d}{d x}\)C(x)

= \(\frac{d}{d x}\)(0.005x3 – 0.02x2 + 30x + 500)

= 0.005 × 3x2 – 0.02 × 2x + 30 + 0

= 0.015x2 – 0.04x + 30

Now, marginal cost when 3 units arei produced

MC(3)= 0.015(9) – 0.04(3) + 30

= 0135 – 0.12 + 30= 30.015

Answer:

127.2

Step-by-step explanation:

The area of a semicircle is:

[tex]\frac{\pi r^{2} }{2}[/tex]

So to figure it out we first find the diameter:

18÷2=9

Then we plug it into the equation

[tex]\frac{9^{2}\pi }{2} = \frac{81\pi}{2}[/tex] Which we can put into a calculator to get 127.2345... so we round to 1 d.p to get our answer, 127.2 (the fifth digit, 3, rounds down)

Answer:

3x³ is a polynomial of degree

The degree of the polynomial 3x³ is 3

The value of x when m(x) = 0 is 8.

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables but does not have exponents to the variables or the exponent of the variable is 1.

The given function is,

m(x) = -3/4 x + 6

Here the value of m(x) depends on the value of x.

m(x) = 0

-3/4 x + 6 = 0

-3/4 x = -6

x = -6 ÷ -3/4

x = 6 × 4/3

x = 8

Hence when m(x) = 0, the value of x is 8.

We can conclude from answering the above question that the first two patterns of the matrix  form a sequence in the third from top with the numbers 4-2-6.

A matrix is a set of numbers arranged in rows and columns. learns about the elements and dimensions of matrices and introduces them for the first time. A rectangular grid of numbers in rows and columns is known as a matrix. Matrix A, as an illustration, has two rows and three columns. Its single row and 1 n row matrix order are the reasons behind its name. A = [1 2 4 5] is a row matrix of order 1 by 4, for instance. P = [-4 -21 -17] of order 1-by-cubic is another illustration of a row matrix.

Step-by-step explanation:

Shaun's percentage of winning against Mike is 8/11 or 73%

Shaun's percentage of winning against Tim is 7/12 or 58%

Shaun's percentage of losing against Mike is 100-73 = 27%

Shaun's percentage of losing against Tim is 100-58 = 42%

Shaun's percentage of losing against Mike and Tim is .27 x .42 which is approximately 11%

Answer: 6 is how many apples are left

Step-by-step explanation:

g(6) must be greater than 21 which is 22 only.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable.

Since g'(x) > 0 for all x and we know that g(x) is an increasing function.

Additionally, since g"(x) > 0 for all x, we know that g(x) is a concave-up function.

Since g(x) is increasing, we know that g(6) > g(5) = 18.

Now, we can use the fact that g(x) is concave-up to find a lower bound on g(6).

By the definition of concave-up, we know that the slope of the tangent line to g(x) is increasing.

This means that the slope of the line connecting (3,g(3)) to (5,g(5)) is less than the slope of the line connecting (5,g(5)) to (6,g(6)).

Using this information, we can find a lower bound on g(6):

g(5)- g(3) / (5-3) < g(6)- g(5)/ (6-5)

18- 12/2 < g(6)- 18

3 < g(6) - 18

g(6) > 21

Therefore, g(6) must be greater than 21.
