can someone explain to me how to get 338 root 2 as the answer
Answers
Answer:
13√2
Step-by-step explanation:
The square root of 338 is expressed as √338 in the radical form and as (338)½ or (338)0.5 in the exponent form. The square root of 338 rounded up to 5 decimal places is 18.38478. It is the positive solution of the equation x2 = 338. We can express the square root of 338 in its lowest radical form as 13 √2.
√338 = √13^2x2 = V13^2 x √2 = 13√2
13√2 = 13 x 239/169 = 239/13 = 18.385

How to Crammers Rule to find k in this equation
Answers
Answer:
k = -1/2 or 2
Step-by-step explanation:
For equations ...
ax +by +c = 0
dx +ey +g = 0
Cramer's Rule tells you the solutions are ...
x = (-ce +gb)/(ae -db)
y = (-ga +dc)/(ae -db)
In order for these equations to be consistent, the solution for any pair of them must be the same. It is sufficient for us to find 'k' such that the values of x are the same.
__
first and third equations
x = (-1·7 +1·(k+1))/(1·7 -3·(k+1)) = (k -6)/(4-3k)
second and third equations
x = (3·7 +1·5)/(2k·7 -3·5) = 26/(14k -15)
__
For these values to be the same, we must have ...
(k -6)/(4-3k) = x = 26/(14k -15)
(k -6)(14k -15) = (4 -3k)(26) . . . . . cross multiply
14k² -99k +90 = -78k +104 . . . . . simplify
14k² -21k -14 = 0 . . . . . . . . . . . . . put in standard form
7(2k +1)(k -2) = 0 . . . . . . . . factor
The solutions are the values of k that make the factors zero: k=2, k=-1/2.
These equations will be consistent if k = -1/2 or k = 2.

Additional comment
Using our above expression for x, we can find the value of x for the solution x = -1/2 to be ...
x = 26/(14(-1/2) -15) = 26/(-22) = -13/11
The first equation tells us the corresponding value of y will be ...
x +(-1/2 +1)y +1 = 0
y = -2(x+1) = -2(-13/11 +11/11) = 4/11
For k = -1/2, (x, y) = (-13/11, 4/11).
The attached graph shows the solution for k=2.
For k = 2, (x, y) = (2, -1).

The Undefined term is csc(3pi) and sec(-pi/2) .
What is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
As, Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to 0. The value of sin (pi) is 0, so the cosecant of pi must be undefined.
Thus, csc(3pi) is undefined
and, the value of The value of cos (pi/2) is 0, so the secant of (pi)/2 must be undefined.
Thus, sec(-pi/2) is also undefined.

Step-by-step explanation:
The formula of the area of a rectangle is given by A=L*W
Where L: is the length of the rectangle
And W: is the width of the rectangle
In the above figure, given that:
L=2x-5
W=x
A=50
This forms the equation:
(2x-5)(x)=50
Expand it:
2x^2 - 5x = 50
We are left with the quadratic equation: 2x^2 - 5x - 50 = 0
(a=2, b=-5, c=-50)
To solve a quadratic equation we have to find it's discriminant and check whether it is <0, >0, or =0
Note:
If discriminant<0, the equation has no real root
If discriminant>0, the equation has two real roots in the form of x1=(-b-redical discriminant) / 2a
x2=(-b+redical discriminant) / 2a
If discriminant=0, the equation has one real root in the form of x=-b/2ac
Now, back to our problem:
discriminant= b^2 - 4ac
= (-5)^2 - 4(2)(-50)
= 25 + 400= 425
discriminant=425>0 so the equation has two real roots
x1=(-b-redical discriminant) / 2a
= (-(-4)-redical(425)) / 2(2)
=(4-5redical(17)) / 4
x2=(-b+redical discriminant) / 2a
=(-(-4)+redical(425)) / 2(2)
=(4+5redical(17)) / 4
So as the final answer x=(4+5redical(17)) / 4 or
x=(4-5redical(17)) / 4

Answer:
x = 6.40
Step-by-step explanation:
The formula to find the area of the rectangle is :
Area = Length × Width
Given that,
Area ⇒ 50
Length ⇒ ( 2x - 5 )
Width ⇒ x
So now we can write an expression like this.
Area = Length × Width
50 = x ( 2x - 5 )
And now we can solve for x.
Let us solve now by using the completing square method.
x ( 2x - 5 ) = 50
2x² - 5x = 50
First divide the whole equation by 2.
x² - 2.5 = 25
x² - 2.5 + 1.5625 = 25 + 1.5625
( x - 1.25 )² = 26.5625
x - 1.25 = ±√26.5625
x - 1.25 = ±5.1538
So,
x = + 5.1538 + 1.25 or x = - 5.1538 + 1.25
x = 6.40 x = -3.90
As we cannot get a negative number as a value for length,
x = 6.40

Step-by-step explanation:

so for 6 hours of work, you'd do 144 x 6 = 864
Since 30 minutes is 2 outta 4 quarters, then you'd do 36 x 2 which is 72
