Answer:
Correct. He transformed the triangle according to the rule (x, y) → (–y, x)
Step-by-step explanation:
Given
F(3, 2), H(4, 5), G 1, 2)
F'(-2, 3), H'(-5, 4), G'(-2, 1)
Find
Whether the triangle was correctly transformed using the rule ...
(x, y) → (–y, x).
Solution
For point F, we have ...
x = 3
y = 2
Then the rule tells us the point F' should be ...
F' = (-y, x) = (-2, 3)
This is the point Quinton found for F', so his transformation was correct. (We can similarly verify that H' and G' are also correct.)
Answer:
The answer is A. Correct. He transformed the triangle according to the rule (x, y) → (–y, x).

A spinner with 5 equal sections labeled 1-5 is spun 50 times. The results are shown in the table. What is the experimental probability of spinning a 1?
Answer:
10
Step-by-step explanation:
Spinner divided to 5 equal parts
It is Numbered from (1 to 5): 1, 2, 3, 4, 5
Theoretical probability of spinning 1 = 1/5
Number of times it is spun = 50
Let Experimental probability of spinning 1 = x
1/5 = x/50
5x = 50
x = 50/5
x = 10
Experimental probability of spinning 1 = 10
Answer:
10

Topic: Percentage
Answer:
329.31
Step-by-step explanation:
The total percentage we have to add is
5+7+1+ .75 =13.75 %
Take the cost of the ticket and multiply by the percentage
289.50 * 13.75%
Change to decimal form
289.50* .1375
39.80625
Rounding to the nearest cent
39.81
Add this to the cost of the ticket
289.50+39.81
329.31
What is the amplitude and period of f(t)=2.5tan(t)
A. amplitude: 2.5; period: π
B. amplitude: 2.5; period: 2π
C. amplitude: none; period: 2π
D. amplitude: none; period: π
I selected A, and I do not know why I got it wrong.
Answer:
D
Step-by-step explanation:
Tan graphs are a bit different to sin and cos graphs: they don't have an amplitude.
If you look at a tan graph, it exists between assymptotes and has no maximum or minimum value. In this case, the 2.5 acts similar to a dilation factor and makes the graph skinnier or wider.
You were right about the period: it is just pi, not 2 pi like sin and cos. Again, if you look at the graph, the assymptotes occur every period, which is only pi.

pleaseeeeee help with math. i’ve gotten no help today. explantion needed!!
Answer:
Exactly two distinct zeros
Step-by-step explanation:
y = 2(x-1) (x + 4)
Plug y = 0
0 = 2(x-1) (x + 4)
0/2 = (x-1) (x + 4)
(x-1) (x + 4) = 0
(x-1) = 0 or (x + 4)= 0
x = 1 or x = - 4
Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.

A student is doing a reading assignment. After 37 minutes of reading, she skims the pages ahead and estimates that she still has 55% of the reading to do. According to the girl's estimate, how long is the total reading assignment? Round to the nearest minute.
Answer:
82 minutes.
Step-by-step explanation:
So first calculate the percentage 37 minutes is. It is 45%
Next find how much 1% is.
Divide by 45.
[tex]\frac{37}{45}[/tex]
Multiply by 100 to find how much the whole time is: [tex]\frac{3700}{45}[/tex]
The decimal version is: 82.2222222222...
Which simplifies to 82 minutes.
Answer:
82 mins
Step-by-step explanation:
percentage of pages she has already read
100-55= 45%
45%----------- 37mins
55%------------ x mins
x =( 37× 55)/45
x= 45.22 mins
approximately x=45 mins
The time for reading assignment is 37mins + 45 mins = 82 mins.

After being exposed to an electromagnet shrinking machine, Joe’s height decreased by 120 cm over 1.5 seconds. His height decreased by the same amount each second. How much did Joe’s height change each second?
Answer:
-80cm/sec
Step-by-step explanation:
It is given that Joe was being exposed to an electro magnet shrinking machine.
Because of this his height started decreasing.
The decrease was at a constant rate per second is given.
In 1.5 seconds, the height decreased by 120 cm.
Since given as constant decrease per second we find that this is direct variation of height over second.
variation per second =
Change in each second would be with negative sign indicating decrease
Answer: -80cm

What is the inverse of f(x) =1/3x +3
Answer:
h(x) = 3x - 6
Step-by-step explanation:
To find the inverse of a function, you have to switch the x- and y-values.
y = 1/3x + 2
x = 1/3y + 2
(x) - 2 = (1/3y + 2) - 2
x - 2 = 1/3y
(x - 2)(3) = (1/3y)(3)
3x - 6 = y
y = 3x - 6

Find the slope of the line going through the points (0,6) and (-3,9)
Answer:
The slope of the line is 5.
The point slope form of the line is y=5x+6.
Step-by-step explanation:
We can find the slope using this formula: [tex]\frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }[/tex]
[tex]\frac{6}{0} -\frac{9}{-3} =[/tex]
[tex]\frac{6}{0} -(-\frac{9}{3} )=[/tex]
[tex]\frac{6}{0} +\frac{9}{3} =[/tex]
[tex]\frac{15}{3} =[/tex]
5
The slope of the line is 5.
To find point slope form, we use the equation y=mx+b where m is the slope and b is the y-intercept.
The y-intercept of this slope is 6 and the slope is 5 so we get, y=5x+6
A city's mean minimum daily temperature in February is 22 degrees Upper F. Suppose the standard deviation of the minimum temperature in February is 6 degrees Upper F and that the distribution of minimum temperatures in February is approximately Normal. What percentage of days in February has minimum temperatures below freezing left parenthesis 32 degrees Upper F right parenthesis?
Answer:
Probability that X <32 degrees
[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )
Step-by-step explanation:
Given that a city's mean minimum daily temperature in February is 22 degrees Upper F, with std deviation 6 degrees.
Let X be the minimum temperature in February
Then X is N(22,6)
To calculate percentage of days in February has minimum temperatures below freezing (32 degrees Upper F )
Probability that X <32 degrees
[tex]=P(Z<\frac{32-22}{6}) =P(Z<1.67)\\ = 0.9522[/tex]
Convert this into percent by multiplying by 100
95.22% of days in February has minimum temperatures below freezing (32 degrees Upper F )

During his hike, Milt drank 1 liter of water and 1 liter of sports drink. How many milliliters of liquid did he drink?
Answer:
2000 ml of liquid
Step-by-step explanation:
1l plus 1l will equal 2l.
1 liter consists of 1000 milliliters ("milli" means thousand).
If 1l had 1000ml, 2l will have 2000ml.
So 2000mlnis the answer
El área de un trapecio es 120 m², la altura 8 m, y la base menor mide 10 m. ¿Cuánto mide la otra base?
Answer:
El soluccion es 20m.
Step-by-step explanation:
Para encontrar la base major necesitas saber el area, la altura, y el base menor.
Puedes usar la formula para la area de un trapecio: [tex]A=\frac{a+b}{2} *h[/tex]
Pero se puede cambiar por lo que es en términos de encontrar la base más grande:
[tex]b=2\frac{A}{h} -a\\A=Area\\h=altura\\a=base-menor\\b=base-major[/tex]
Y si conectas las variables que conoces, siempre podrás encontrar la que no tienes
[tex]b=2\frac{120}{8} -10\\b=20[/tex]
