Let a, b, and c be the length of 3 corresponding sides of the triangle. The following inequality must always be true since they form a triangle :
[tex]a+b>c[/tex]
(This inequality says that the sum of two sides must always be greater than the other side)
Let's use this inequality for x, 1.3, and 4.1
[tex]x+1.3>4.1[/tex]
(The reason why 1.3 is on the left side is because it is the smaller side)
Subtract both sides by 1.3
[tex]x>2.8[/tex]
x must always be greater than 2.8. Now, let's see what value x must be always less than.
[tex]1.3+4.1>x[/tex]
[tex]5.4>x[/tex]
x must be always less than 5.4. Let's combine both statements for x and we get:
[tex]2.8<x<5.4[/tex]
These are the only values of x that will make it possible for these sides to form a proper triangle.

The shortest leg of a right triangle is 27 units. The other leg is 36 units. What is the length of the hypotenuse?
Answer:
Length of Hypotenuse: 45
Step-by-step explanation:
To solve this we need to use the pythagorean theorem.
a^2 + b^2 = c^2
In this case: a = 27
b = 36
27^2 + 36^2 = c^2
729 + 1296 = 2025
then we need to find the square root of 2025
45^2 = 2025

In the figure below, \overline{AD} AD start overline, A, D, end overline and \overline{BE} BE start overline, B, E, end overline are diameters of circle PPP. What is the arc measure of \stackrel{\LARGE{\frown}}{CD} CD ⌢ C, D, start superscript, \frown, end superscript in degrees? ^\circ ∘ degrees
Answer:
The measure of the arc CD = 64°
Step-by-step explanation:
It is required to find the measure of the arc CD in degrees.
So, as shown at the graph
BE and AD are are diameters of circle P
And ∠APE is a right angle ⇒ ∠APE = 90°
So, BE⊥AD
And so, ∠BPE = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)
From (1) and (2)
∴ 33k - 9 = 90
∴ 33k = 90 + 9 = 99
∴ k = 99/33 = 3
The measure of the arc CD = ∠CPD = 20k + 4
By substitution with k
∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°

Answer:
x - 2y - 7 = 0
Step-by-step explanation:
To find the equation of a line that passes through (-5, -3) and (3,1)
All we need to do is to use the find the slope and then plug it into the straight line equation
straight line equation : y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
[tex]x_{1}[/tex] = -5 [tex]y_{1}[/tex] = -3 [tex]x_{2}[/tex] = 3 [tex]y_{2}[/tex] = 1
m = slope = [tex]y_{2}[/tex] - [tex]y_{1}[/tex] / [tex]x_{2}[/tex] - [tex]x_{1}[/tex]
= 1 -(-3) / 3 -(-5)
=4/8
=1/2
m=1/2
So, we can now plug in our value into the equation;
y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
y - (-5) = [tex]\frac{1}{2}[/tex] [x - (-3)]
y + 5 = [tex]\frac{1}{2}[/tex](x+3)
y + 5 = [tex]\frac{x + 3}{2}[/tex]
cross-multiply
2(y + 5) = x + 3
2y + 10 = x + 3
take 2y and 10 to the right-hand side of the equation;
x + 3 - 2y - 10 = 0
x - 2y - 7 = 0
Therefore the equation of the line is x - 2y - 7 = 0

Solve for K, the constant of variation, in a joint variation problem where y=520, x=5, z=6.5. Solution is?
Answer:
K = 676
Step-by-step explanation:
When y is directly proportional to x and inversely poportional to z
We have
y = kx/z
When y =520
x = 5
z = 6.5
K =?
We have
520 = k x 5/6.5
Cross multiply
520 x 6.5 = 5k
3380 = 5k
Divide both sides by 5
3380/5 = 5k/5
676 = k
k = 676

Dividing Polynomials with Tables Isiah is dividing 2x3 - x2 + 2x + 5 by x + 1 using a division table. His work is shown here. What is the value of A?
Answer:
5
Step-by-step explanation:
We are asked to find the value of A. We know from the question that we need to have the sum of -3x and (A)x equal the third term of the original polynomial, which is 2x. written out in an equation, it looks like this.
[tex]-3x+(A)x=2x[/tex]
We can simplify the equation if we add 3x to both sides, which then leaves us with this.
[tex](A)x=5x[/tex]
We can further simplify the equation by dividing both sides by x. This leaves us with our last equation for this problem.
[tex]A=5[/tex]
Finally, we have our answer. We can also verify that this is a valid integer by multiplying our, now completed, quotient by the divisor and adding the remainder, which in this case, our remainder is 0, so we will not be including it in our operation.
[tex](x+1)(2x^{2}-3x+5)[/tex]
If our calculations were all correct, the product of these polynomials should equal our dividend, verifying our integer is valid; lo' and behold, it is.

Answer:
x = 5Step-by-step explanation:
[tex]3x+5=20\qquad\text{subtract 5 from both sides}\\\\3x+5-5=20-5\\\\3x=15\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{15}{3}\\\\x=5[/tex]
Answer:
x = 5.
Step-by-step explanation:
3x +5 = 20
Subtract 5 from both sides:
3x + 5 - 5 = 20 - 5
3x = 15
Divide both sides by 3:
x = 15/3
x = 5.

What are the end behaviors of f(x) = -2(x - 2)5?
O
A. Both ends go down.
O
B. The left end goes down; the right end goes up.
O'C. Both ends go up.
O
D. The left end goes up; the right end goes down.
Answer:
Step-by-step explanation:
D.The left end goes up and the right end goes down because this is a first order function
The end behavior of the function f(x) = -2(x - 2)^5 is that the left end goes up and the right end goes down. This is determined by the odd degree and negative leading coefficient of the function.
Explanation:The end behaviors of a function can be determined by looking at the highest degree term, also known as the leading term. In this case, for the function f(x) = -2(x - 2)^5, the highest degree is odd (5), and the coefficient, -2, is negative.
Odd degree with a negative leading coefficient means that the end behaviors of this function will be: as x approaches negative infinity (moves left), the function values will go toward positive infinity (up), and as x approaches positive infinity (moves right), the function values will go toward negative infinity (down).
So the correct option here is: D. The left end goes up; the right end goes down.

(3x2 - 15x) - 18 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
3x2 - 15x - 18 = 3 • (x2 - 5x - 6)
Trying to factor by splitting the middle term
3.2 Factoring x2 - 5x - 6
The first term is, x2 its coefficient is 1 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -6
Step-1 : Multiply the coefficient of the first term by the constant 1 • -6 = -6
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .
-6 + 1 = -5 That's it

The supplement of an angle is six times as large as the complement of the angle. What is the measure of the angle to the nearest whole degree?
Solution:
Complementary angles add up to 90° and supplementary angles add up to 180°
Let "a" be the required angle
Supplement of an angle = 180 - a
Complement of angle = 90 - a
The supplement of an angle is six times as large as the complement of the angle.
Therefore,
180 - a = 6(90 - a)
Simplify the above
180 - a = 540 - 6a
6a - a = 540 - 180
Combine the like terms
5a = 360
Divide both sides by 5
a = 72
Thus the measure of the angle to the nearest whole degree is 72 degrees
