The function f is given in three equivalent forms.
Which form most quickly reveals the zeros (or "roots") of the function?
Choose 1 answer:
f(x) = 1/2(x-5)^2-2
f(x)= 1/2(x -3) (x -7)
f(x) = 1/2x^2-5x+21/2
Write one of the zeros

Answers

Answer:

a) best form: (b) f(x)= 1/2(x -3) (x -7)

b) zeros: x=3, x=7

Step-by-step explanation:

The factored form most quickly tells you the zeros of the function. The zeros are the values of x that make the factors zero: the opposite of the binomial's constant.

f(x)= 1/2(x -3)(x -7) reveals the zeros to be x=3 and x=7

The sum lf two numbers is 10. The difference between the two numbers is 4: what is the smaller numerical?

Answers

Answer:

Step-by-step explanation:

The two numbers are 3 and 7, and 3 is the smaller one

Step-by-step explanation:

x, y are the 2 numbers.

x + y = 10

y - x = 4

that gives us

y = x + 4

and we use that in the first equation :

x + x + 4 = 10

2x = 6

x = 3

y = x + 4 = 3 + 4 = 7

so, yes, the smaller number is 3.

Answers

Answer:

2x - 3y = 19

Step-by-step explanation:

y=(-5--1)/(2-8)*(x -8)+-1

y=-4/-6(x-8)-1

3y=2x-16-3

3y=2x-19

2x-3y=19

Answer:

2x - 3V = 19
Step-by-step explanation:

y=(-5--1)/(2-8)*(x-8)+-1

Answer:

x = 65, y = 25

Step-by-step explanation:

Given system of linear equations:

x + y = 90 2x - y = 105

Add up the equations to eliminate y:

x + 2x = 90 + 1053x = 195x = 65

Find y:

y + 65 = 90y = 90 - 65y = 25

1. Assume O P || NM.
What are possible lengths for each of the following segments?
LO, ON, LP, and PM
Choose one measure for each segment. You can start with the length of any segment, but remember to consider the
Triangle Proportionality Theorem when choosing the measurements.
2. How did you decide what values to use? Explain how you chose your measurements, and why you know they are
possible measurements for the segments.
3. What is a different method you could use to choose these numbers? Explain your answer.

Answers

1. Assuming OP || NM, considering the triangle proportionality theorem possible measurements for the segments are: ON = 3 units, LO = 1 unit, PM = 6 units, LP = 2 units

2. The possible values are decided by assuming [tex]\frac{ON}{LO} = \frac{PM}{LP} = 3[/tex] using the triangle proportionality theorem.

3. Another method is applying the AA Similarity Theorem to compare corresponding side lengths of the triangles that are proportional to each other.

What is the Triangle Proportionality Theorem?

Triangle proportionality theorem states that if a line is parallel to one of the sides of a triangle intersects two of the other two sides, it divides the two sides into proportional corresponding segments.

1. Assuming that OP || NM, we would apply the triangle proportionality theorem to have the following ratio:

[tex]\frac{ON}{LO} = \frac{PM}{LP}[/tex]

Using the above ratio, we can choose the following possible lengths for the segments:

ON = 3 units

LO = 1 unit

PM = 6 units

LP = 2 units

2. The values are decided assuming that the ratio, [tex]\frac{ON}{LO} = \frac{PM}{LP} = 3[/tex]

This means that the ratio of the proportional segments, irrespective of the their measurement should give you an assumed equal ratio of 3:1.

Therefore, since:

[tex]\frac{3}{1} = 3\\\\\frac{6}{2} = 3[/tex]

The measurements, ON = 3 units, LO = 1 unit, PM = 6 units, LP = 2 units are therefore possible measurements.

3. Using the AA Similarity Theorem to prove that ΔLPO ≅ ΔLMN, the corresponding sides of both triangles will be proportional.

LP/LM = LO/LN = PO/MN

We can use this to choose possible measurements while assuming a ratio between the proportional sides of both triangles.

Let's assume that: LP/LM = LO/LN = PO/MN = 1/4

Let,

LO = 1 unit

LN = 4 units

Therefore, ON = LN - LO = 4 - 1 = 3 units.

Same way the other possible measures can be gotten provided a ratio is assumed.

Sophia wants to buy a pair of shoes online. Shop X has a price of 35.90 CAD. The price at
Shop Y is 21 British pounds (GBP). Compare the prices using Canadian dollars. If 1 CAD =
0.75 GBP, which shop offers a better deal? Explain.

Answers

Answer:

Shop Y

Step-by-step explanation:

In order to compare, we need to make both the same units first. Since they give us the conversion factor 1 CAD=0.75 GBP, we can plug this in to the shoes from shop X. We get 35.90*0.75=26.93 GBP.

Now we can compare. Since 21 GBP < 26.93 GBP, we can see that shop Y's shoes are cheaper, and therefore the better deal.

Explain why Question 9 is based on the source below:The advent of printing ought to be featured more prominently by historians of science when they explain the downfall of outdated scientific ideas that occurred during the Scientific Revolutions after 1500. For it was printing, and the creation of mass numbers of books, that led directly to empiricism: the theory that all knowledge is derived from sense-experience and experimentation, as well as the refinement of the scientific method of observation, experimentation, and publishing of the results of those experiments. For it was printing that created that all-important text for researchers of all kinds: the secondary source.The Renaissance scholars made eliminating errors one of their major goals, since the copying work of medieval scribes often involved the perpetuation [spread] of terrible errors from original sources. This drive for error-correction inspired the scientists of the Scientific Revolution to conduct experiments to make sure that knowledge was directly observable and verifiable. These scientists would then publish the results of their experiments in order to correct the scientific record. These published experimental results formed a base of secondary sources that could be used by each next generation of scientists as they made new discoveries and advances in the fields of physics, astronomy, medicine, anatomy, mathematics and geometry, geography and cartography.Printing increased the faith that scientists could have in written sources, making archival research a trusted and required part of the scientific process. Scientists also began publishing their findings in journals and magazines limited entirely to scientific ideas, created a European society of scientists in constant written conversation with each other.Excerpt from The Printing Revolution in Early Modern Europe, Elizabeth Eisenstein, 1983.9.
