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

$0.84\leq x \leq 7.16$

A 30 ft building casts a shadow that is 75 ft. long. A nearby tree casts a shadow that is 35 ft. long. How tall is the tree?

Whitepunk [10]

Answer:

The tree is 14 ft. tall.

Step-by-step explanation:

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
