The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops. The retail markup, can be represented by the function. Which function can be used to find the marked-up price of a marble countertop depending on the area?

Answers

Answer:

[tex]m(c(a)) = 4.8875a[/tex]

Step-by-step explanation:

The missing parameters are:

[tex]c(a) = 4.25a[/tex] --- Cost of marble countertops

[tex]m(c) = 1.15c[/tex] --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

[tex]c(a) = 4.25a[/tex]

[tex]m(c) = 1.15c[/tex]

[tex]m(c) = 1.15c[/tex] can be written as:

[tex]m(c(a)) = 1.15*c(a)[/tex]

Substitute: [tex]c(a) = 4.25a[/tex]

[tex]m(c(a)) = 1.15*4.25a[/tex]

[tex]m(c(a)) = 4.8875a[/tex]

Hence, the cost of marked up price is: [tex]m(c(a)) = 4.8875a[/tex]

The 25th term of the given arithmetic sequence is -19.

The given arithmetic sequence is 53, 50, 47, 44, 41.

What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is an=a+(n-1)d

Here the first term of the sequence is a=53 and the common difference is

50-53=-3

Put, a=53, d=-3 and n=25 in the general form an arithmetic sequence, we get

a25=53+(25-1)×(-3)

= 53+24×(-3)

= 53-72

= -19

Therefore, the 25th term of the given arithmetic sequence is -19.

How do I solve this arithmetic sequence?

Answers

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82

a. y=2sin50
b. y=5sinpi0
c. y=5sin20
d. y=5sin1/2 0

Answers

Answer:

c is correct

Step-by-step explanation:

if u have the equation y = a sin b (x),

a is the amplitue (regardless of + or - before it) and 2pi / b = period. so we can deduce that a = +5 or -5 and b = 2, but then it says a>0, so therefore a must be 5 and b is still 2, so the equation is y= 5 sin2(O)

EASY! which equation can be used to solve x in the diagram??

a) 13x - 5x = 180

b) 5x + 13x = 90

c) 5x + 13x = 180

d) 5x = 13x

no links picture above

Answers

Answer:

C) 5x + 13x = 180

Step-by-step explanation:

As, the sum of the angles of the above diagram is 180 °

So if we add them we get 180°

So, 5x + 13x = 180°

So option (C) is right

To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).
