Answer:
Is the volume of a square is 12.167, the length of a side is 2.3
Step-by-step explanation:
First you need to think what is the formula that relates the length of a side and the volume in a square. If we called x to the side and V(x) the volume, we have that V(x) = x³ ⇒ 12.167 = x³.
So, if we have to find the length of the side, we should apply ∛V(x)
⇒ ∛(12.167) = x ⇒ 2.3 = x
The length of a side of a square with a volume of 12.167 is 2.3.
Answer:
200
Step-by-step explanation:
Total number of people surveyed = 800
Number of people who like rock = 700
Number of people who like country = 300
Let the number of people who like both genres = x
Among the 700 people who like rock there are some people who like country as well likewise among the 300 people who like country there are some people who like rock as well. So those who like both genres are being counted twice, once in 700 and once in 300. So if we subtract the number of people who like genres from 700 or 300 we will get the total number of people as shown below:
i.e.
800 = 700 + 300 - x
x = 700 + 300 - 800
x = 200
This means, 200 people like both genres.
From we can also say 500 people like only rock, 100 people like only country and 200 people like both.
Answer:
3u - 2v + w = 69i + 19j.
8u - 6v = 184i + 60j.
7v - 4w = -128i + 62j.
u - 5w = -9i + 37j.
Step-by-step explanation:
Note that there are multiple ways to denote a vector. For example, vector u can be written either in bold typeface "u" or with an arrow above it . This explanation uses both representations.
.
.
.
There are two components in each of the three vectors. For example, in vector u, the first component is 11 and the second is 12. When multiplying a vector with a constant, multiply each component by the constant. For example,
.
So is the case when the constant is negative:
.
When adding two vectors, add the corresponding components (this phrase comes from Wolfram Mathworld) of each vector. In other words, add the number on the same row to each other. For example, when adding 3u to (-2)v,
.
Apply the two rules for the four vector operations.
<h3>1.</h3>
Rewrite this vector as a linear combination of two unit vectors. The first component 69 will be the coefficient in front of the first unit vector, i. The second component 19 will be the coefficient in front of the second unit vector, j.

Answer:
Top Right
Step-by-step explanation:
all the brackets are in the form (X, Y), Y=P(x)
just replace the X's in the brackets with the X's in the Options, if P(x) is the number that's in place of Y in the brackets, then that option is the correct one, in this case the top Right one. if this helped, please mark as brainliest
