Answer:
Step-by-step explanation:
The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. These features are illustrated in (Figure).
Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.
The y-intercept is the point at which the parabola crosses the y-axis. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x
at which
y = 0

Answers
Answer:
x = 30
Step-by-step explanation:
We start off with 90 degrees
2x + x = 90
Add all like terms
3x = 90
Divide 3 on both sides
[tex]\frac{3x} {3} = \frac{90} {3}[/tex]
x = 30
To check your answer:
Let x be 30
2x + x = 90
2 (x 30) + 30 = 90
60 + 30 = 90
90 = 90

5 boxes will cose 5 x 15.40 = 77 normally.
according to the table, he will get 6.5% discount.
6.5 percent of 77 is 77x0.065 = 5.005 ≈ 5
Answer:
he orders 5 boxes of paperclips, that comes around to 77 dollars. That means he will get a 6.5 percent discount. So you would multiply 77 by .065 and you would get 5.005. You would take that number and subtract it by 77 and would get 71.995 and you can round that up to 72 dollars. My guess is that either 72 or 5.005 is the answer as 72 dollars is the price after the discount and 5.005 is how much he is saving

csc^-1 4.25 to degrees
Answers
9514 1404 393
Answer:
13.609°
Step-by-step explanation:
The csc^-1 function is the arccosecant function. It gives the angle whose cosecant is given. If we let A represent that angle, your statement is ...
A = csc^-1(4.25)
It is used to solve the relation ...
4.25 = csc(A)
__
Some calculators can give you the value directly (see attached). Most cannot. In any event, you need to make sure the angle mode for the calculator is set to degrees.
When your calculator does not have the csc^-1 function, you can make use of the trig identity ...
csc(x) = 1/sin(x)
In the above equation, this becomes ...
4.25 = 1/sin(A)
sin(A) = 1/4.25 . . . . . solve for sin(A)
All scientific and graphing calculators will have the inverse sine (arcsine) function.
A = sin^-1(1/4.25)
A ≈ 13.609° . . . . . . . calculator mode in Degrees
_____
Additional comment
For inverse functions, especially inverse trig functions, I find it useful to read them as ...
csc^-1(x) ⇒ "the angle whose cosecant is x"
sin^-1(x) ⇒ "the angle whose sine is x"
This reminds me that the value it gives is an angle (degrees or radians), and the argument it takes is a pure number (one with no units).

Step-by-step explanation:
2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.
Answer:
1. 9
2.
Step-by-step explanation:
1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:
640 - 30x = 370
Now, subtract both sides by 640 to get -270:
-30x = -270
Last, divide both side by -30:
-30x = 270
x = 9
Now, we know she withdraws $30 for 9 months.

------------------------------FOLLOW MEA bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.
Answers
Answer:
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
Step-by-step explanation:
Let
Mass of brown eggs = x
Mass of white eggs = y
3y + 2x = 13 (1)
5y + 4x = 24 (2)
Multiply (1) by 5 and (2) by 3 to eliminate y
15y + 10x = 65 (3)
15y + 12x = 72 (4)
Subtract (3) from (4)
12x - 10x = 72 - 65
2x = 7
x = 7/2
x = 3.5
Substitute x = 3.5 into (1)
3y + 2x = 13 (1)
3y + 2(3.5) = 13
3y + 7 = 13
3y = 13 - 7
3y = 6
y = 6/3
y = 2
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
