I am assuming it's asking this? I'm not too sure.
Answer:
[tex](4b - 5 {)}^{2} [/tex]
Step-by-step explanation:
1) Rewrite it in the form a² - 2ab + b², where a = 4b and b=5.
[tex](4b)^{2} - 2(4b)(5) + {5}^{2} [/tex]
2) Use square of Difference: (a - b)² = a² - 2ab + b².

Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Shape A
has b = 9.6 and h = 5.8, then
A = 0.5 × 9.6 × 5.8 = 27.84 m²

The licensed practitioner has ordered gemcitabine 400 mg/m^2 IV for a patient whose BSA is 0.47 m^2. You have on hand a 200 mg vial of gemcitabine for injection that contains 38 mg per mL. How much medication should this patient receive?
Answer:
4.95 mL
Step-by-step explanation:
Since we have 400 mg/m² of gemcitabine for a patient whose BSA is 0.47 m², the mass of drug required for the patient is thus m = 400 mg/m² × 0.47 m² = 188 mg.
Also, since 200 mg vial of gemcitabine for injection that contains 38 mg per mL, so the concentration of gemcitabine is 38 mg/mL.
Since concentration = mass/volume, and
volume = mass/concentration,
the volume of gemcitabine injection required is
V = mass of gemcitabine/concentration of gemcitabine in injection
V = 188 mg/38 mg/mL
V = 4.95 mL

6. The graph shows the number of soda bottles a machine can make over time. Use the two points (2, 50) (6, 150) shown to find the number of soda bottles the machine can make
per minute.

Answer:
150-50/6-2
100/4
25
Step-by-step explanation:
25 soda bottles the machine can make per minute.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
We have to use the two points (2, 50) (6, 150) shown to find the number of soda bottles the machine can make per minute.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
x₁=2, y₁=50, x₂=6, y₂=150
substitute in slope formula
Number of soda bottles=slope=150-50/6-2
=100/4
=25
Hence 25 soda bottles the machine can make per minute.

What is the length of a kite string that is 6 meters above and 9 meters away from where it is being held? Round to the nearest tenth.
Answer:
10.8 meters
Step-by-step explanation:
This situation forms a right triangle, where the length of the kite string is the hypotenuse, the distance from where it is held is the long leg, and the height is the short leg.
Use the pythagorean theorem to solve for c, the length of the kite string.
a² + b² = c²
6² + 9² = c²
36 + 81 = c²
117 = c²
10.8 = c
So, the length of the kite string is 10.8 meters
