Answer:
4 - [tex]\sqrt{6}[/tex]
Step-by-step explanation:
Rationalise the denominator by multiplying the numerator and denominator by the conjugate of the denominator.
the conjugate of 4 + [tex]\sqrt{6}[/tex] is 4 - [tex]\sqrt{6}[/tex] , then
= [tex]\frac{10(4-\sqrt{6}) }{(4+\sqrt{6})(4-\sqrt{6}) }[/tex] ← expand denominator using FOIL
= [tex]\frac{40-10\sqrt{6} }{16-6}[/tex]
= [tex]\frac{40-10\sqrt{6} }{10}[/tex] ( divide terms on numerator/ denominator by 10 )
= 4 - [tex]\sqrt{6}[/tex]

LHS = RHShence it is verified that value of x is 40°
Answer:
x = 40°Step-by-step explanation:
In the question we arw given with three angles that are z
Angle 1 = x°Angle 2 = 70°Angle 3 = 110°( Angle 1 , Angle 2 or Angle 3 aren't given in Question , we are just giving names for given angle . So that there's ease on explanation )
And we have asked to find th value of angle 1 i.e. x .
Solution : -
As we can see in the question that ,
Angle 1 + Angle 2 = Angle 3 ( Vertically Opposite Angles )Vertically Opposite Angles : -
When two lines intersect each other then the two angles formed by them at a specific point are equal .
[tex] \longmapsto x° + 70° = 110°[/tex]
Subtracting 70 from both sides :
[tex]\longmapsto x° + \cancel{70° }- \cancel{70° }= 110° - 70°[/tex]
On further calculation :
[tex] \longmapsto \purple{ \boxed{ \mathfrak{ x° = 40 {°} }}}[/tex]
Therefore , value of x is 40° .Verification : -
We are verifying our answer by substituting value of x . So ,
x + 70° = 110°40° + 70° = 110°110° = 110°L.H.S = R.H.SHence , Verified .Therefore, our value for x is correct

Answer:
D. g(x) = (3/2)(3^x)
Step-by-step explanation:
"Dilation" means the function is multiplied by some value. The y-intercept of f(x) is 3^0 = 1. We notice the y-intercept of g(x) is greater than 1, so the multiplier must be greater than 1.
The only such choice is ...
g(x) = 3/2(3^x) . . . . . choice D
__
Additional comment
g(1) is not 4.5 for choices A and B, so those can be eliminated. g(0) is not 3/2 for choice C, so that can be eliminated.

Answer:
Step-by-step explanation:
Are these the two equations?
−5x+y=−1
−5x+y=10
=====
Put them into slope-intercept form of y = mx + b
−5x+y=−1
y = 5x - 1
−5x+y=10
y = 5x + 10
Both have a slope of 5, so they will not intersect. This means there are no solutions.

Look at the figure below:
An image of a right triangle is shown with an angle labeled y.
If sin y° = a divided by 6 and tan y° = a divided by b, what is the value of cos y°? (6 points)
Step-by-step explanation:
since I don't see a figure here, I have to use only the written information.
we need to remember :
tan(angle) = sin(angle) / cos(angle)
so, we have here
a/b = a/6 / cos(y) = a/(6×cos(y))
a×6×cos(y) = a×b
cos(y) = a×b / (a×6) = b/6
The measure of angle t is 60 degrees. What is the x-coordinate of the point where the terminal side intersects the unit circle? One-half StartFraction StartRoot 2 EndRoot Over 2 EndFraction StartFraction StartRoot 3 EndRoot OVer 2 EndFraction
Answer:
(a) 1/2
Step-by-step explanation:
The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...
(x, y) = (cos(α), sin(α))
When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.

The equations are x + y = 34 and 12x + 8y = 312. The number of adults and children will be 10 and 24, respectively.
What is the solution to the equation?In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.
Let 'x' and 'y' be the number of adults and children, respectively. Then the equation is given as,
x + y = 34 ...1
12x + 8y = 312 ...2
From equations 1 and 2, then we have
12x + 8(34 - x) = 312
12x + 272 - 8x = 312
4x = 40
x = 10
The value of 'y' is calculated as,
10 + y = 34
y = 24

Step-by-step explanation:
The sum of interior angles of a quadrilateral is 360°.
(14x -11)° +(8x +7)° +(5x +18)° +(10x +13)° = 360°
37x +27 = 360 . . . . . . divide by °, collect terms
37x = 333 . . . . . . . . subtract 27

There is a pole located in a garden. The pole’s base is 4.5 feet west and
5.1 feet north of a brick that marks the entrance of the garden. A bird is
sitting on top of the pole. If the pole is 6 feet tall, approximately how far
is the bird from the brick that marks the entrance of the garden?
A. 6.8 feet
B. 7.5 feet
C. 7.9 feet
D. 9.1 feet
The distance between the bird and the brick is 7.5 feet. Hence the correct answer is B. It is to be noted that the question is an exercise relating to solving the sides of a right-angled triangle.
What is the formula for finding the sides of a right-angled triangle?
The formulas for finding the sides of a right-angled triangle are:
For Side A, a = [tex]\sqrt{ (c^{2} - b^{2} })[/tex]
For Side B, b = [tex]\sqrt{ (c^{2} - a^{2} })[/tex]
For Side C, c = [tex]\sqrt{ (a^{2} + b^{2} })[/tex]
In this case, base - b has been given as 4.5 feet;
the height - a of the pole has been given as 6 feet. Note that the portion due west is a trick addition that is irrelevant to the solution.
Hence, c is equaled: [tex]\sqrt{ (6^{2} + 4.5^{2} })[/tex]
= [tex]\sqrt{ ( 36+ 20.25 })[/tex]
= [tex]\sqrt{56.25}[/tex]

Step-by-step explanation:
the general equation for a line is usually
y = ax + b
a is the slope (the inclination) of the line indicating how flat or steep (and up or down) the line goes. it is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.
and b is the y-intercept, the y value for x=0, the point, where the line intercepts the y-axis.
the origin is the point (0, 0).
that gives us the y-intercept (b) right away, as this is therefore clearly the point, where the line intercepts the y-axis. so, b = 0.
and going from (0, 0) to (-2, 10) we see
x changes by -2 (from 0 to -2).
y changes by +10 (from 0 to 10).
so, the slope is +10/-2 = -5.
and the line equation is
y = -5x
[tex]\huge \text{Hello there! :)}[/tex]
Answer:
[tex]y=-5x[/tex]
Step-by-step explanation:
Given that the equation of a line passes through the origin and the point (-2,10), we can get the equation of the line below.
The slope-intercept form of the equation of the line is given as;
[tex]y=mx+b[/tex]
where m = slope and y = intercept
The formula for the slope is given as
[tex]\frac{y^{2-yx^{1} } }{x^{2-x^{1} }}[/tex]
The given points are the origin are (0,0) and (-2, 10)
[tex]m=\frac{10~-~0}{-2~-0} =\frac{10}{-2} =-5[/tex]
Now use the point-slope formula to solve for the equation of the line.
[tex](y-y^{1})=m(x-x^{1})[/tex]
For this situation, we are given the slope of -5 and (-2,10)
[tex]y-10=-5(x-(-2))[/tex]
[tex]y-10=5x-10[/tex]
[tex]Y+5x=+10-10[/tex]
[tex]y+5x=0[/tex]
[tex]y=-5x[/tex]
Therefore, the Answer is [tex]y=-5x[/tex]

The relationship between money earned and hours worked is linear. Joe computes the slope between (4, 30) and (12, 90), then computes the slope between (4, 30) and (10, 75). How do the two slopes compare?
The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the x-axis.
The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the y-axis.
The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.
The slope between (4, 30) and (12, 90) is less because 4 is a factor of 12 and 30 is a factor of 90.

Step-by-step explanation:
∠ 5 and ∠ 3 are same- side interior angles and sum to 180° , that is
10x + 5 + 8x - 5 = 180 , so
18x = 180 ( divide both sides by 18 )
x = 10
