X-y+5z=3 4x+z=0 x+3y+z=-9

Mathematics
1 answer:
igor_vitrenko [27]3 years ago
3 0

x - y + 5z = 3   ....  (1)

4x + z = 0         .......(2)

x + 3y + z = -9  .......(3)

From (2) z = -4x,   Substitute for  z in (1) and (3):-

x - y + 5(-4x) = 3

-19x + y = 3 ......(4)

x + 3y - 4x = -9

-3x + 3y = -9

- x + y = -3  .....(5)

Subtract:-  (4) - (5) we get

-18x = 0

x = 0

So z = -4x = 0

Substituting for x and z in equation (3):-

3y = -9

y = -3

Answer is x = 0 , y = -3 and z = 0

The composite function combines the palm tree and the seed functions

The composite function is t(d) = 60d + 20

<h3>How to determine the composite functions</h3>

The functions are given as:

Number of palm trees: t(s) = 3s + 20

Number of seeds: s(d) = 20d

The composite function that represents the number of palm trees Carlos can expect to grow over a certain number of days is represented as:

t(s(d))

This is calculated as:

t(s(d)) = 3s(d) + 20

Substitute s(d) = 20d

t(s(d)) = 3 * 20d + 20

Evaluate the product

t(s(d)) = 60d + 20

Rewrite as:

t(d) = 60d + 20

Hence, the composite function is t(d) = 60d + 20

Describe the correct answer to this problem including units what is the surface area of the figure
Brrunno [24]

Answer:

<h2>        A = 22.5π ft² ≈ 70.686 ft²</h2>

Step-by-step explanation:

A = π×(2.5)² + π×2.5×6.5 = 6.25π + 16.25π = 22.5π ≈ 70.686 ft²

{6.5 ft is not a height, it's slant length}
