Convert the equation to standard form:
f(x) = 2(x - 1)(x + 4)
Answer:
2x^2 - 10x - 8.
Step-by-step explanation:
f(x) = 2(x - 1)(x + 4)
= 2(x^2 - x - 4x - 4)
= 2(x^2 - 5x - 4)
= 2x^2 - 10x - 8.
Referring to question 1, what is the predicted strength of a weld with a diameter of 51?
The predicted strength is an illustration of a linear regression
The predicted strength of a weld with a diameter of 51 is -503.2
How to determine the predicted strength?The equation of the predicted strength is given as:
Strength = -941.6992 + 8.5988*Diameter
Substitute 51 for diameter
Strength = -941.6992 + 8.5988*51
Evaluate the sum
Strength = -503.1604
Approximate
Strength = -503.2
Hence, the predicted strength of a weld with a diameter of 51 is -503.2

The predicted strength is an illustration of linear regression.
The predicted strength of a weld with a diameter of 51 is -503.2.
What is linear regression?Linear regression strives to show the relationship between two variables by applying a linear equation to observed data.
The equation of the predicted strength is given as:
Strength = -941.6992 + 8.5988 × Diameter
Substitute 51 for diameter
Strength = -941.6992 + 8.5988 × 51
Strength = -941.6992 + 438.5898
Strength = -503.1604
Strength = -503.2
Hence, the predicted strength of a weld with a diameter of 51 is -503.2.

Volunteers from the Band Booster Club have already cleaned 2 rows of bleachers and will continue to clean at a rate of 7 rows per minute. The leadership class has completed 11 rows and will continue working at 4 rows per minute. Once the two groups get to the point where they have cleaned the same number of rows, they will take a break and decide how to split up the remaining work. How long will that take? How many minutes will each group have cleaned by then?

Answer:
18 is 30% of 60
Step-by-step explanation:
Try to line up percents % and the actual numbers they represent.
number : precent
60 is 100%
18 is x %
cross multiply
x·60 = 100·18
divide both sides by 60 to isolate x
x = ((100·18)/60
x = 30

-> 15*12=180m
Then find the area of the half circle, the formula of the area of a circle is [tex]\pi r^2[/tex]
here it's half a circle so it's [tex]\frac{\pi r^2}{2}[/tex] where r is 12
-> [tex]3.14\cdot \frac{\left(12\right)^2}{2}=226.08 m[/tex]
Finally just add the area of the rectangle with the area of the half circle

First lets start with the rechtangle:
A = L * W
A = 17 * 7 = 119
the area of the rechtangle is 119
Now the triangle the formula is a little diffrent but it is the same concept
A=hbb (Picture below, it wont let me write it out right)

Answer:
The Scale Factor is 5.3
Step-by-step explanation:
Here's the reason why:
You are trying to make the rectangle much larger.
The 14yd by 6yd is trying to get to the 74.2yd by 31.8yd.
We need to remember the importance of length and width.
If 14 yards is our length then 74.2 yards is our length on the enlarged rectangle.
You must do 74.2/14 because we need to work backwords.
**You can't find something to multiply 14 by to get to 74.2 unless you do division.**
74.2/14 is 5.3
Now do the same with the width.
31.8/6
That is 5.3 as well.
Therefore the scale factor is 5.3
