Explicación paso a paso:
Si A, B y C son números enteros, según la propiedad distributiva;
A (B + C) = AB + AC
tenga en cuenta que A se distribuyó sobre B y C
Aplicando esto para expandir la expresión dada -4. (-5 + 3)
-4. (-5 + 3)
= -4 (-5) + -4 (3)
= 20 + (-12)
= 20 - 12
= 8
Por lo tanto, la respuesta requerida es 8
Answer:
True. See the explanation and proof below.
Step-by-step explanation:
For this case we need to remeber the definition of linear transformation.
Let A and B be vector spaces with same scalars. A map defined as T: A >B is called a linear transformation from A to B if satisfy these two conditions:
1) T(x+y) = T(x) + T(y)
2) T(cv) = cT(v)
For all vectors 
and for all scalars 
. And A is called the domain and B the codomain of T.
Proof
For this case the tranformation proposed is t: 
Where 
For this case we have the following assumption:
1) The transpose of an nxm matrix is an nxm matrix
And the following conditions:
2) 
And we can express like this 
3) If 
and then we have this:
And since we have all the conditions satisfied, we can conclude that T is a linear transformation on this case.
Answer:
The volume of a sphere varies with the cube of the radius. Since the Earth is 3.67 times the moon's radius (6371/1736), it has 49.4 times the volume.

Answer:
(P+9s+21)/3
Step-by-step explanation:
hello :
P/3 + (3s + 7) = P/3 + 3(3s + 7)/3 = (P+9s+21)/3
The probability that the plant manufactures a part between 10.8 and 12.8 centimeters 13%
<h3>How to find the probability that the part is between 10.8 and 12.8 centimeters</h3>
The probability is solved z scores, this measures the amount of standard deviation sample X is from mean. the formula is below
z = (X - μ) / σ
<u>Definition of variables</u>
mean, μ = 16.3 centimeters
standard deviation, σ = 2.5 centimeters
X = 10.8 and 12.8 centimeters
z score, z
substituting into the formula
for X = 12.8 centimeters
= (X - μ) / σ
= (12.8 - 16.3) / 2.5
= -1.4
the p value for z of -1.4 = 0.161513
for X = 10.8 centimeters
= (X - μ) / σ
= (10.8 - 16.3) / 2.5
= -2.2
the p value for z of -2.2 = 0.027807
the probability is calculated as below
0.161513 - 0.027807= 0.133706
= 0.13
=13%
