Which of the following is a situation in which an equation CANNOT be solved using the quadratic formula ?
Answer:
C. One term has degree 3
Step-by-step explanation:
The quadratic formula is used to find the zeros of degree 2 polynomials. The coefficient of the linear term does not matter, and the coefficient of the x² term may be anything except 0.
If the degree of the polynomial is 3, the quadratic formula does not apply.
Two people meet in the conference room on the fourth floor of a building. On departure, one person travels West
24 feet, South 18 feet, and Down 18 feet. The other person travels North 24 feet, East 12 feet, and Up 18 feet.
How far apart are the two people? Round to the nearest tenth.
Answer:
36*(5)^0.5
Step-by-step explanation:
distance on horizontal 36 feet
distance on vertical 78 feet
so distance between them = (36^2+78^2)^0.5 = 36*(5)^0.5
The two people are 66 feet apart from each other.
How to elaborate the problem ?
The 1st person travels 24 feet west, 18 feet south and 18 feet down.
The location of 1st person is (-24, -18, -18) , the negative sign is to convert all in same direction.
The 2nd person travels 12 feet east, 24 feet north and 12 feet up.
The location of 2nd person is (12, 24, 18)
How to find the distance between them ?The distance between (-24, -18, -18) & (12, 24, 18 = [tex]\sqrt{(-24-12)^{2}+(-18-24)^{2}+(-18-18)^{2} }[/tex] feet
= [tex]\sqrt{(-36)^{2}+(-42)^{2}+(-36)^{2} }[/tex]) feet
= 66 feet

33 markers cost $5.79
Which equation would help determine the cost of 13 markers
Answer:
3/$5.79 = 13/x
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x. Divide $5.79 by three to get the cost of one marker, $1.93. Then multiply the cost of one marker by 13 on the left. This will get the total value which is $25.09.

this is for my geometry final please help me pass
Step-by-step explanation:
cos(x) = 5/13
the relation is
sin²(x) + cos²(x) = 1
so,
sin²(x) + (5/13)² = 1
sin²(x) + 25/169 = 169/169
sin²(x) = 144/169
sin(x) = 12/13

Answer:
2(3-√13) is the answer
Step-by-step explanation:
Given that,
x = \frac{3 - \sqrt{13} }{2}
or, \frac{1}{x} = \frac{2}{3 - \sqrt{13} } (Taking reciprocal on both sides)
We know that,
(a + b)² = a² + b² + 2ab
or, (x \ + \frac{1} {x})^{2} = {x}^{2} + \frac{1}{x {}^{2} } + 2
or, {x}^{2} + \frac{1}{x {}^{2} } = (x \ + \frac{1}{x })^{2} - 2
Now,
or, {x}+ \frac{1}{x } = \frac{3 - \sqrt{13} }{2} + \frac{2}{3 - \sqrt{13} }
or, (3 - \sqrt{13 {})^{2} } + 4
2(3-√13) is the answer

Ashley arranged the following list of numbers below: 5,2,7,8,2,5,3. Find the mean and median.
find the solution of y=x+3 and y=2x+6
Answer:
x = 3 and y = 0
Step-by-step explanation:
To find the solution where you have two equations is called a System of Equations.
What you do is you notice there are two equations and the let both equations equal each other. We can do this because both equations start with a y. These "y" work like puzzles and you can connect the "x+3" and "2x + 6" together. Then solve for it. Here's what i mean,
y = x+3
y = 2x+6
Now connecting them,
x+3 = 2x+6
Subtract x from both sides
3 = x + 6
Subtract 6 from both sides,
x = -3
Now solve for y,
y = -3 + 3 = 0
So our solution is x = 3 and y = 0.
Answer:
(x, y) = (-3, 0)
Step-by-step explanation:
Substitution or elimination work well for solving this system of equations.
__
EliminationSubtract the first equation from the second.
(y) -(y) = (2x +6) -(x +3)
0 = x +3
-3 = x . . . . . . . subtract 3
y = (-3) +3 = 0 . . . . use the first equation to find y
(x, y) = (-3, 0)
__
SubstitutionUse the second equation to substitute for y in the first.
2x +6 = x +3
x = -3 . . . . . . . . . subtract x+6 from both sides
y = (-3) +3 = 0 . . . . find y using the first equation
(x, y) = (-3, 0)
