how is 1/14x42=3 can someone? explain
Answer:
This is why [tex]\frac{1}{14}[/tex] x 42 = 3
Step-by-step explanation:
[tex]\frac{1}{14}[/tex] x 42 can also be written as [tex]\frac{1}{14}[/tex] x [tex]\frac{42}{1}[/tex]
we can reduce diagonally by 7 so [tex]\frac{1}{14}[/tex] x [tex]\frac{42}{1}[/tex] = [tex]\frac{1}{2}[/tex] x [tex]\frac{6}{1}[/tex]
now we multiply across [tex]\frac{1}{2}[/tex] x [tex]\frac{6}{1}[/tex] = [tex]\frac{6}{2}[/tex]
6 divided by two or [tex]\frac{6}{2}[/tex] = [tex]\frac{3}{1}[/tex] or 3

In simplest radical form, what are the solutions to the quadratic equation 0 =3x4x + 5?
Quadratic formula: x= btyb- 4ac
Given:
The quadratic equation is
[tex]0=-3x^2-4x+5[/tex]
To find:
The simplest radical form of the solution.
Solution:
Quadratic formula:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]0=-3x^2-4x+5[/tex]
Here, a=-3, b=-4 and c=5. Putting these values in the quadratic formula, we get
[tex]x=\dfrac{-(-4)\pm \sqrt{(-4)^2-4(-3)(5)}}{2(-3)}[/tex]
[tex]x=\dfrac{4\pm \sqrt{16+60}}{-6}[/tex]
[tex]x=\dfrac{4\pm \sqrt{76}}{-6}[/tex]
[tex]x=\dfrac{4\pm 2\sqrt{19}}{-6}[/tex]
Taking 2 common, we get
[tex]x=\dfrac{2(2\pm \sqrt{19})}{-6}[/tex]
[tex]x=\dfrac{(2\pm \sqrt{19})}{-3}[/tex]
[tex]x=-\dfrac{(2\pm \sqrt{19})}{3}[/tex]
Therefore, the correct option is A.

The value of a baseball player's rookie card began to increase once the player retired. When he retired in 1999 his card was worth $4.99. The value has increased by $1.73 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2006? Express the relationship with an equation. y=(Use integers or decimals for any numbers in the expression.)
Answer: $15.37
Yes, proportional
Step-by-step explanation:
Ok So the Equation Here is
y = 1.73x + 4.99
The reason why 4.99 doesn't have a variable is because of the fact it's not being manipulated by time like the 1.73 is. It's a flat rate of 4.99 for the card itself, no increase or decrease in years. However, the 1.73 is affected by how ever many years the player is in retirement. That's why it has X because the amount of 1.73 needs to be multiplied by however many years hes been in retirement.
So Substitute 6 (because 2006 is what year we need to find) for x and we get
y = 1.73(6) + 4.99
Which if you simplify in a calculator or do it in your paper, comes out to be $15.37

I need help with this one
Answer:
that's your answer
(\tan ^(2)\theta \cos ^(2)\theta -1)/(1+\cos (2\theta ))=
(tan²(θ) cos²(θ) - 1) / (1 + cos(2θ))
Recall that
tan(θ) = sin(θ) / cos(θ)
so cos²(θ) cancels with the cos²(θ) in the tan²(θ) term:
(sin²(θ) - 1) / (1 + cos(2θ))
Recall the double angle identity for cosine,
cos(2θ) = 2 cos²(θ) - 1
so the 1 in the denominator also vanishes:
(sin²(θ) - 1) / (2 cos²(θ))
Recall the Pythagorean identity,
cos²(θ) + sin²(θ) = 1
which means
sin²(θ) - 1 = -cos²(θ):
-cos²(θ) / (2 cos²(θ))
Cancel the cos²(θ) terms to end up with
(tan²(θ) cos²(θ) - 1) / (1 + cos(2θ)) = -1/2

Option b) 3x - 22 = 38 should be the correct answer.
Step-by-step explanation:
If we solve the equation, we get:
x = 20
So each bag had 20 apples. In total, 3 bags held 60 apples. If he gives away 22 apples to his friends, he has 38 remaining and this satisfies the discription given in the question.
Therefore, option B) 3x -22 = 38 should be your answer.
A 33 33 -ft ladder leans against a building so that the angle between the ground and the ladder is .
Question:
A 33 foot ladder leans against a building so that the angle between the ground and the ladder is 75º. How high does the ladder reach up the side of the building?
Round to 2 decimal places feet.
Answer:
[tex]H = 31.88[/tex]
Step-by-step explanation:
The question is illustrated using the attachment as a sketch.
We have that
[tex]Ladder = 33ft[/tex]
[tex]\theta = 75[/tex]
Required
Determine how high the ladder is to the building
Represent the length of the ladder with L and how high the ladder is on the building with H.
The relationship between L, H and [tex]\theta[/tex] is"
[tex]Sin\theta = \frac{H}{L}[/tex]
Substitute values for L and [tex]\theta\\[/tex]
[tex]Sin(75) = \frac{H}{33}[/tex]
Make H the subject
[tex]H = 33 * Sin(75)[/tex]
[tex]H = 33 * 0.9660[/tex]
[tex]H = 31.88[/tex]
Hence, the height to which the ladder reaches is approximately 31.88ft
