Answer:
3.26
Step-by-step explanation:
Rounding to the nearest hundredth means round to the nearest two decimal places.
To do this, all we need to look at is the 3rd decimal place.
Since 4 is not 5 or greater, that means we must round down, no matter how close it is to 5.
Therefore, the answer should just be 3.26
Answer:
3.26
Step-by-step explanation:
You round the second place after the decimal (6) by the place after it (4).
If the place after the number you need to round is a 5 or up, the decimal you round goes up one, if it is a 4 or lower it stays the same.
E.G. if 3.2649 was 3.2659 the hundreds would be rounded to 3.27. Since it's a 4, the six stays the same at 3.26.]

Solve for c.
3 − 7c − 20c = 7(–7c − 19) + 14c
c =
Answer:
[tex] \boxed{c = -17} [/tex]
Step-by-step explanation:
[tex] = > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17[/tex]
Answer:
c = -17
Step-by-step explanation:
→Distribute the 7 to (-7c - 19):
3 - 7c - 20c = -49c - 133 + 14c
→Add like terms (-7c and -20c, -49c and 14c):
3 - 27c = -35c - 133
→Add 35c to both sides:
3 + 8c = -133
→Subtract 3 from both sides:
8c = -136
→Divide both sides by 8:
c = -17

Step-by-step explanation:
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]

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.

Heather is flying a kite at the park. The string makes an angle of 53° with the level ground. The kite is 28 meters above the ground. How long is the string from heather.To the kite?
Answer:
35.06 meters
Step-by-step explanation:
This represents a right angled triangle.
The height of the kite above the ground represents the opposite side while the length of the string of the heather of the kite is the hypotenuse.
We need to find the hypotenuse, h.
We can use the sine part of the trigonometric function SOHCAHTOA:
sin(Ф) = opp / hyp
where opp is the side opposite the angle
hyp is the hypotenuse
=> sin(53) = 28 / h
h = 28 / sin(53)
h = 35.06 meters
The length of the string from the heather to the kite is 35.06 meters

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

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

when graphed which equation will yield the same maximum value as the graph of y = -3x^2 + 6x + 9 ?
a) y = -3(x - 1)^2+12
b) y = -3(x + 1) ^2 - 12
c) y = 3(x - 1)^2 -12
d) y = 3(x + 1)^2 + 12
Answer:
A
Step-by-step explanation:
Graphed below are all 5 graphs. The one in red is the original, but it cannot be seen because it is entirely concealed by the blue graph, or graph A. Since they are the same graph, they must share all characteristics, including a maximum value. Therefore, the correct answer is choice A. Hope this helps!

find the value of x
m<2 = 9x - 1
Answer: x=9
Step-by-step explanation:
The bottom triangle that has a 40° is an isosceles triangle, therefore the other angle at the bottom right is also 40°. This leaves the top angle to be 100°.
180=40+40+x
180=80+x
x=100
Now, to find ∠2, you can tell it is a supplementary angle. Therefore, the 2 angles add up to 180°
180-100=∠2
80°=∠2
The problem states that ∠2 is 9x-1. We know that ∠2 is 80°. We can solve for x.
80=9x-1
81=9x
x=9

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
