Answer:
X=9
Step-by-step explanation:
Get the variables on one side by adding 3 to both sides making it
2x=18 divide it then by 2 getting X
Answer: A)Sin(33)= x/14
Step-by-step explanation:
Hi, to answer this question we have to apply the next trigonometric function:
sin α = opposite side / hypotenuse
Where α is the angle, the hypotenuse is the longest side of the triangle (in this case 14), and the opposite side to the angle is x.
Replacing with the values given:
Sin(33)= x/14
Feel free to ask for more if needed or if you did not understand something.
The length of the rectangle equals 80 cm, and the width equals 32 cm.
Divide the length to the width, we get the ratio between them :
80 : 32
Now, we simplify by dividing them both by the same number, in this case it's 16
=> 80 : 32 = (80 : 16) : (32 : 16) = 5:2
So, the ratio between the length and the width is 5:2
Consider a homogeneous machine of four linear equations in five unknowns are all multiples of 1 non-0 solution. Objective is to give an explanation for the gadget have an answer for each viable preference of constants on the proper facets of the equations.
Yes, it's miles true.
Consider the machine as Ax = 0. in which A is 4x5 matrix.
From given dim Nul A=1. Since, the rank theorem states that
The dimensions of the column space and the row space of a mxn matrix A are equal. This not unusual size, the rank of matrix A, additionally equals the number of pivot positions in A and satisfies the equation
rank A+ dim NulA = n
dim NulA =n- rank A
Rank A = 5 - dim Nul A
Rank A = 4
Thus, the measurement of dim Col A = rank A = five
And since Col A is a subspace of R^4, Col A = R^4.
So, every vector b in R^4 also in Col A, and Ax = b, has an answer for all b. Hence, the structures have an answer for every viable preference of constants on the right aspects of the equations.
