Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = $\frac{adjacent}{hypotenuse}$ = $\frac{ZY}{XZ}$ = $\frac{12.6}{XZ}$

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = $\frac{12.6}{cos29}$ ≈ 14. 4 ( to 3 sig. figs )

pentagon [3]

Answer:

Part A: The rate of change was greater in case of the graph.

Part B: The figure shows the graph of function A in Redline and Function B in blue line

Part C : Initial value of function B is greater than Function A.

Step-by-step explanation:

Here, Function A show graph of a line and Function show table show a set of value of x and y.

Part A). Which function show greater rate of change.

The slope of line is given by m = $\frac{Y2-Y1}{X2-X1}$

For function A:

Given graph passes through points (04) and (2,12)

The slope of line is m= $\frac{12-4}{2-0}$

= $\frac{8}{2}$

= 4

For function B:

Given the table has points (012) and (2,14)

The slope of line is m= $\frac{14-12}{2-0}$

= $\frac{2}{2}$

= 1

Therefore, The rate of change was greater in case of graph.

Part B). Plot the graph of a function B onto the graph of a function A

The figure shows the graph of function A in Redline and Function B in blueline

Line of function A is more tilted toward the y-axis than Line of function B.

Therefore, Rate of change of function A is greater than Function B.

Part C). Which function has greater initial value?

For function A:

From the graph of part B,

When x=0 y=4

For function B:

From the graph of part B,

When x=0 y=12

Therefore, Initial value of function B is greater than Function A.

X over 2x+1. What is x?

tatiyna

Answer:

$x= - \frac{1}{2}$

Step-by-step explanation:

Given:

$\frac{2x+1}{x}$

Let us assume that this equation is equal to 0.

Hence $\frac{2x+1}{x}=0$

Now Solving the above equation we get,

$\frac{2x+1}{x}=0\\\\2x+1=0\\2x=-1\\x= - \frac{1}{2}$

Hence by solving the equation we get $x= - \frac{1}{2}$
