Use the inequality x2−8x+6≤0 and graphing calculator, or another piece of technology, to answer Part A and Part B. Part A: What
Kryger [21]

Answer:

Part A) The zero's of the function are x=0.84, x=7.16

Part B) The solution set is the interval  [0.84,7.16]

Step-by-step explanation:

we have

x^2-8x+6\le0

Using a graphing calculator

Part A) What are the zeros of the inequality to the nearest hundredth?

The zero's of the function are the values of x when the values of the function are equal to zero

see the attached figure

The zero's of the function are

x=0.84, x=7.16

Part B) What is the solution set for the inequality?

The solution set is the interval  [0.84,7.16]

All real numbers greater than or equal to 0.84 and less than or equal to 7.16

0.84\leq x \leq 7.16

Height of the building/ Height of the tree  = Shadow of building/ Shadow of tree

30/x = 75/35           Cross multiply

75x = (30)(35)

75x = 1050

x = 1050/75

x = 14

A sector with a central angle measure of 200 degrees has a radius of 9 cm. What is the area of the sector?
Sergio [31]

Answer:

\boxed{Area\ of\ sector = 141.4\ cm^2}

Step-by-step explanation:

Radius = r = 9 cm

Angle = θ = 200° = 3.5 radians

Now,

Area \ of \ sector = \frac{1}{2} r^2 \theta

Area = 1/2 (9)²(3.5)

Area = 1/2 (81)(3.5)

Area = 282.7 / 2

Area of sector = 141.4 cm²
