Determine an equivalent expression by rationalizing the denominator: (5√3)/(4-√6)
Step-by-step explanation:
so when you want to rationalize the denominator when it's in the form [tex](a-\sqrt{b})[/tex] you multiply by the conjugate which is [tex](a+\sqrt{b})[/tex] which is where the sign is the opposite. This is because it's using the difference of squares to get rid of the square root. Because [tex](a-b)(a+b) = a^2-b^2[/tex] this will remove the square root since it's going to become square and the ab - ab will cancel so there will be no square root
Multiply by conjugate
[tex]\frac{5\sqrt3}{4-\sqrt6} * \frac{4+\sqrt6}{4+\sqrt6}\\[/tex]
Simplify:
[tex]\frac{20\sqrt{3} + 5\sqrt{6 * 3}}{16-6}[/tex]
Simplify radical

eric borrowed 5,000 to buy a used car. he agreed to make monthly payments of 175.00 for 36 months how much will how actually pay the bank
If Eric agreed to make monthly payments of 175.00 for 36 months, the total amount of money he will pay the bank is 6,300.
How much will Eric pay the bank?
Given that;
Amount of money borrowed = 5000Monthly payment = 175.00Number of month = 36Total amount of money paid to the bank = ?To determine the total amount of money that Eric will pay the back, we simply multiply his monthly payment and the number of months.
175.00 × 36
= 6,300
Hence, if Eric agreed to make monthly payments of 175.00 for 36 months, the total amount of money he will pay the bank is 6,300.

Triangles L M N and P O N connect at point N. Angles L M N and N O P are congruent.
Why is the information in the diagram enough to determine that △LMN ~ △PON using a rotation about point N and a dilation?
because both triangles appear to be equilateral
because∠MNL and ∠ONP are congruent angles
because one pair of congruent corresponding angles is sufficient to determine similar triangles
because both triangles appear to be isosceles, ∠MLN ≅ ∠LMN, and ∠NOP ≅ ∠OPN
Answer: because ∠MNL and ∠ONP are congruent angles
Step-by-step explanation:
Options 1 and 4 are wrong because we cannot base our answer on assumptions from the diagram.
Option 3 is wrong because you need two pairs of corresponding congruent angles to prove similar triangles, not just 1.

What is the Area of a Rectangle?Area of a rectangle = (length)(width).
Given the vertices:

Step-by-step explanation:
A triangle has integer length sides. If two sides of the triangle are 16 and 21, how many possible lengths are there for the third side
There are 31 possible lengths for the third side.
Unknown Side + 16 > 21
Unknown Side > 5
16 + 21 > Unknown Side
37 > Unknown Side
Unknown Side < 37
So, the possible integer lengths range from
6 - 36
= 36 - 6 + 1
= 31 possible lengths
The length of the third side of a triangle has to continually be among (but not equal to) the sum and the distinction among the alternative facets. As an instance, take the example of two, 6, and seven. and consequently, the 0.33 facet length has to be extra than four and less than eight.

Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
y = 5x-17
y = x + 3
OA. (5,8)
OB. (4,7)
O C. (1,-12)
OD. (5,-17)
Answer:
A(5 ; 8)
Step-by-step explanation:
y = 5x - 17
y = x + 3
5x - 17 = x + 3
⇔ 5x - x = 3 + 17
⇔ 4x = 20
⇔ x = 20/4
⇔ x = 5
y = 5 + 3 = 8
So (5 ; 8)
Answer:
We can use the substitution method to solve the system of equations.
Since y = x + 3, we can substitute this expression for y in the first equation:
y = 5x - 17
x + 3 = 5x - 17
Subtracting x from both sides, we get:
3 = 4x - 17
Adding 17 to both sides, we get:
20 = 4x
Dividing both sides by 4, we get:
x = 5
Substituting this value of x into either equation, we get:
y = x + 3 = 5 + 3 = 8
Therefore, the correct ordered pair is (5, 8), which corresponds to the point where the two lines intersect.
The correct answer is (A) (5,8).

An 84-foot building casts a 98-foot shadow. What is the angle that the sun hits the building? HINT: Draw a picture.
Answer:
40.6°
Step-by-step explanation:
The building and the shadow are perpendicular to each other (or intersect at a 90° angle).
Meaning that this is a triangle problem.
We are making a triangle from the building to the shadow and a diagonal line connecting the ends of both.
We need to find the angle at the top of the building. The opposite side of the angle is 84. The adjacent side is 98.
Opposite / Adjacent = Tan X
So if we go to the calculator:
[tex]tan^{-1} (\frac{84}{98}) = 40.6[/tex]

horizontal asymptote of y = -7
Step-by-step explanation:
The parent function is shown on the coordinate plane. The graph of the parent function has a horizontal asymptote (an imaginary line that the graph approaches, but never touches or intersects) of y = 0.
Since the function of g(x) = e^x - 7 is the graph of the parent function translated 7 units down, the function would have a horizontal asymptote of y = -7.

The equation of an ellipse for the graph shown is [tex]\frac{x^2}{5^2} + \frac{y^2}{21^2} = 1[/tex]
How to determine the equation?Since the given coordinates of the vertices and foci have the form (-5, 0) and (5, 0) and (-2, 0) and (2, 0) respectively, this ultimately implies that the major axis of this ellipse is the x-axis.
Thus, the standard form of the equation of this ellipse is given by:

b² = 25 - 4
b² = 21.

In the diagram, ABCDE is a regular pentagon. The sides AB and DC are produced to meet at F. Find the angles x, y and z.
Answer:
x = 108°
y = 72°
z = 36°
Step-by-step explanation:
Finding unknown angles:If all sides are equal in a pentagon, then it is a regular pentagon.
n = the number of sides = 5
Sum of all angles in a pentagon = (n -2) * 180
= (5 - 2)* 180
= 3 *180
= 540°
Sum of each angle of regular pentagon = 540 ÷ 5
= 108°
[tex]\sf \boxed{\bf x= 108^\circ}[/tex]
Linear pair: If the non common arm of adjacent angles form a straight line, then the adjacent angles are called linear pair and they add up to 180°
∠DCB + y = 180 ° {Linear pair}
108 + y = 180
y = 180 - 108
[tex]\sf \boxed{\bf y = 72^\circ}[/tex]
Exterior angle property of triangle: The exterior angle equals the sum of opposite interior angles.
In Δ BCF ,
x = y + z
Now, substitute the values of x and y , and we can find the value of z.
108° = 72 + z
108 - 72 = z
[tex]\sf \boxed{\bf z = 36^\circ}[/tex]

Step-by-step explanation:
the given points are

(6, 4)
so, can you see, how the sequence continues ?
I see immediately that for every 3 additional units of x we add 2 units of y.
so, yes, the next point in the sequence is
(6 + 3, 4 + 2) = (9, 6).
so, this point (or ordered pair) follows the same ratio or proportional relationship between x and y as the points already in the graph.
in other words, they are on the same line following the same slope ("y coordinate change / x coordinate change" when going from one point on the line to another).
