What are the similarities and differences between the standard form and vertex form of a quadratic equation?
Answers
Step-by-step explanation:
Standard form is ax^2 + bx + c. Vertex form is a(x-h)^2 + k, which reveals the vertex and axis of symmetry. Factored form is a(x-r)(x-s), which reveals the roots.

c²=a²+b²
c²=10²+42²
c²=100+1764
c²=1864
c=√1864
c=43.17
c=43.2
Add to the height of the bottom part of the tree.
43.2+10=53.2
∴The total height of the tree before it was struck down was 53.2ft.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

If a car rides at an average speed of 50 miles per hour, How many minutes will it take if the car drives 10 miles?
Answers
Answer:
12 Minutes
Step-by-step explanation:
1/5 of 50 is 10 and 1/5 of 60 is 12 meaning for every 12 minutes 10 miles is driven
Answer:
The car will take 12 minutes to travel 10 miles.Step-by-step explanation:
We know that:
(50 mph) = (50 miles = 1 hour)Work:
50 miles = 1 hour=> 50 miles = 1 hour = 60 minutes=> 50 miles = 60 minutes=> 50 ÷ 5 miles = 60 ÷ 5 minutes=> 10 miles = 12 minutesHence, the car will take 12 minutes to travel 10 miles.

68.80+5%=72.24
Percent is given by :
\(Total .\frac{Percent}{100} = equivalent number to percent\\ 86.\frac{20}{100} =17.2\\86-17.2=68.8\\86.\frac{5}{100} =4.3\)

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

*LAST QUESTION , PLEASE ANSWER TY* (: Quadrilateral ABCD is inscribed in a circle. If angle A measures (3x – 10)° and angle C measures (2x)°, find x.
Answers
\(\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}\)
Actually Welcome to the Concept of the Quadrilaterals.
Basically we know that, the sum of opposite angles of a quadrilateral inscribed in a circle is always 180°.
so applying this law here, we get as,
2X + (3X-10) = 180°
=> 5X - 10° = 180°
=> 5X = 190°
=> X = 190°/5
=> X = 38°
thus the angle X= 38°.
