Calculate the speed of a 5.2 kg object that possesses 26.1 J of kinetic energy
Answers
The speed of object is 3.68m\s.
Given that,
Mass of the object = 5.2 kg,
Object that possesses 26.1 J of kinetic energy.
We have to find,
The speed of the object.
According to the question,
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
If work, which transfers energy, is done on an object by applying a net force, the object speeds up and there by gains kinetic energy.
Then, The formula of kinetic energy is given as,
[tex]K.E = \frac{1}{2} mv^{2}[/tex]
Where, m = mass of the object
And v = speed of the object
Therefore, The speed of the object calculated as.
[tex]KE = \frac{1}{2} mv^{2} \\\\26.1 = \frac{1}{2} \times 5.2\times v^{2} \\\\26.1 = 2.6 \times v^{2} \\\\\frac{26.1}{2.6} = v^{2} \\\\v^{2} = 10.1\\\\v = \sqrt{10.1} \\\\v = 3.68[/tex]
Hence, The speed of object is 3.68m\s.

50 is 20% of what ? Round to the nearest tenth is needed
Answers
Answer:
250
Step-by-step explanation:
20% of 250 is 50. 100% of 250 is 250, therefore 20 percent of 250 equals 50.
More simplified explanation: The question is asking if 50 is 20% of a number, what is the number? So we know that 20% is 1/5 of 100%; if we know that 50 is 20% of something, then we would multiply 50 by 5 to get the answer. We would have to multiply 50 by 5 because if 50 is 20% of a number that would mean that 50 is 1/5 of the number we need to find, so to find the number, you to multiply 50 by 5.

Allison is making treat bags for Valentine's Day. She uses 7 sheets of stickers
and 3 bags of candy for every 8 friends. If Allison is making 14 treat bags, how
many sheets of stickers will she use? How many bags of candy?
Answers
The number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.
What is the ratio?It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.
Allison uses 7 sheets of stickers and 3 bags of candy for every 8 friends.
It means the ratio of the sticker to candy bags:
7:3 for 8 friends
[tex]\frac{7}{8} :\frac{3}{8}[/tex] for 1 friend or
0.875:0.375
If she makes 14 treat bags then:
The number of sheets of stickers she will use = 0.875×14 ⇒ 12.25
The number of bags of candy she will use = 0.375×14 ⇒ 5.25
Thus, the number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.

find g(3)
Let g(x)=9x+24, find g(3).
Answers
Answer:
51
Step-by-step explanation:
Plug in 3 as x into the function:
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24
g(3) = 51
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24 = 51
Answer:g(3) = 51

Consider w=sqrrt2/2(cos(225°) + isin(225°)) and z = 1(cos(60°) + isin(60°)). What is w+ z expressed in rectangular form?
Answers
Answer:
Option (3)
Step-by-step explanation:
w = [tex]\frac{\sqrt{2}}{2}[\text{cos}(225) + i\text{sin}(225)][/tex]
Since, cos(225) = cos(180 + 45)
= -cos(45) [Since, cos(180 + θ) = -cosθ]
= -[tex]\frac{\sqrt{2}}{2}[/tex]
sin(225) = sin(180 + 45)
= -sin(45)
= -[tex]\frac{\sqrt{2}}{2}[/tex]
Therefore, w = [tex]\frac{\sqrt{2}}{2}[-\frac{\sqrt{2}}{2}+i(-\frac{\sqrt{2}}{2})][/tex]
= [tex]-\frac{2}{4}(1+i)[/tex]
= [tex]-\frac{1}{2}(1+i)[/tex]
z = 1[cos(60) + i(sin(60)]
= [tex][\frac{1}{2}+i(\frac{\sqrt{3}}{2})[/tex]
= [tex]\frac{1}{2}(1+i\sqrt{3})[/tex]
Now (w + z) = [tex]-\frac{1}{2}(1+i)+\frac{1}{2}(1+i\sqrt{3})[/tex]
= [tex]-\frac{1}{2}-\frac{i}{2}+\frac{1}{2}+i\frac{\sqrt{3}}{2}[/tex]
= [tex]\frac{(i\sqrt{3}-i)}{2}[/tex]
= [tex]\frac{(\sqrt{3}-1)i}{2}[/tex]
Therefore, Option (3) will be the correct option.

Find the 18th term of the arithmetic sequence whose common difference is d = 2 and whose first term is a, = 3.
Answers
Answer:
The 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]
Step-by-step explanation:
We know that the arithmetic sequence with a common difference 'd' and the first term 'a₁' is defined as
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Given the values
d = 2
a₁ = 3
As we have to determine the 18th term of the arithmetic sequence.
so putting n = 18 in the nth term to determine the 18th term.
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_{18}=3+\left(18-1\right)2[/tex]
[tex]=3+17\cdot \:2[/tex]
[tex]=3+34[/tex]
[tex]=37[/tex]
Therefore, the 18th term of the arithmetic sequence will be:

Answers
Answer:
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.
Step-by-step explanation:
Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*[tex]0.9^{t}[/tex]
Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:
N(1) = 100*[tex]0.9^{1}[/tex]
Resolviendo:
N(1) = 100*[tex]0.9^{1}[/tex]= 100*0.9= 90
De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:
N(5) = 100*[tex]0.9^{5}[/tex]= 100*0.59049= 59.049≅ 60
y t por 10 años:
N(10) = 100*[tex]0.9^{10}[/tex]= 100*0.3487= 34.86 ≅ 35
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

If the equation y=3x−1 y = 3 x − 1 were graphed on the xy-coordinate plane, which of the following would not be a point on that graph?
Answers
Answer:
See Explanation
Step-by-step explanation:
This question requires options.
Since, there are none, I'll answer on a general term.
For a coordinate point to be on the graph, the x and y value when substituted in the given equation must make the equation true.
Take for instance
(x,y) = (1,2)
This implies that
x = 1
y = 2
Substitute values of x and y in
y = 3x - 1
We have:
2 = 3 * 1 - 1
2 = 3 - 1
2 = 2
Notice that both sides of the equation are equal.
Hence
(1,2) lies on the xy coordinate plane.
However,
Take for instance (x,y) = (2,4)
This means
x = 2 and y = 4
Substitute values of x and y in
y = 3x - 1
4 = 3 * 2 - 1
4 = 6 - 1
4 ≠ 5
The above does not represent an equation because 4 is not equal to 5.
Hence, (2,4) does not lie on the coordinate plane
So, to answer your question, you need to substitute values of x and y in the given equation.
Which ever of the options that does not show equality answers your question.
