3/5 == 0.6
Which part of the line is 0.6?
A < 0.5 so there's no way A can be the answer.
C > .75 so it can't be the answer either.
D > 1.5 so it can't be the answer either.
B is the only answer left and it sits just right in front of 0.5, which is close to 0.6.
write the quadratic formula y=x^2-6x+7 in vertex form.
Answer:
Step-by-step explanation:
Start like this: x^2 - 6x = -7. Now you have the x terms on one side and the constant on the other. Take half the linear term (-6x) which is 3 and then square that (9) and add it to both sides, giving you x^2 - 6x + 9 = -7+ 9, or x^2 - 6x + 9 = 2. Now make the left side into the perfect square binomial you created by completing the square: (x-3)^2 = 2, and then move the 2 over to get: (x-3)^2 - 2. That's the vertex form for a parabola with a vertex at (3, -2)

.
Answer:
9
Step-by-step explanation:
At x=0, this function's y-value is simply 10. At x=2, the y-value is 28.
We can figure this out by using the slope formula.
[tex](y^2-y^1)/(x^2-x^1)[/tex]

In a college, there are 800 students in the first year, 950 students in the second year and 1000 students in the third year. If this data were graphed as a pie chart, what would be the size of the angle in the third year?
Answer: [tex]130.9^{\circ}[/tex]
Step-by-step explanation:
Given
The number of students in the first year is 800
The number of students in the second year is 950
The number of students in the third year is 1000
If this data is graphed on a pie chart, then the area percentage of area occupied by third years is
[tex]\Rightarrow \dfrac{1000}{1000+950+800}\times 100=36.36\%[/tex]
Now, the angle around the center of the circle is [tex]360^{\circ}[/tex]
[tex]\therefore \text{angle covered by third years=}0.3636\times 360^{\circ}\\\Rightarrow 130.896\approx 130.9^{\circ}[/tex]
Review the graph of g(x).
On a coordinate plane, a curve goes through (negative 4, 8), curves down through (negative 2, 0), and approaches x = negative 1 in quadrant 3. Another curve approaches x = negative 1 in quadrant 2, has vertex (0, 0), and curves up through (2, 8). Another curve approaches x = 3 in quadrant 4 and curves up through (4, 16).
What are the one-sided limits of g(x) around the vertical asymptote x = –1?
Limit of g (x) as x approaches negative 1 minus = infinity and limit of g (x) as x approaches negative 1 plus = infinity
Limit of g (x) as x approaches negative 1 minus = infinity and limit of g (x) as x approaches negative 1 plus = negative infinity
Limit of g (x) as x approaches negative 1 minus = negative infinity and limit of g (x) as x approaches negative 1 plus = infinity
Limit of g (x) as x approaches negative 1 minus = negative infinity and limit of g (x) as x approaches negative 1 plus = negative infinity

GJ = 360 -68 -31 -115
GJ = 146
Inscribed Angle = 1/2 of intercepted arc
Angle GHJ = 146 / 2 = 73 degrees

numbers is 5. Find the numbers.
9514 1404 393
Answer:
4, -1
Step-by-step explanation:
We can let x and y represent the two numbers. The first relation is ...
2x + 4y = 4
The second relation is ...
x - y = 5
Subtracting the second relation from half the first gives ...
1/2(2x +4y) -(x -y) = 1/2(4) -(5)
3y = -3
y = -1
From the second relation, ...
x = 5 +y = 5 -1 = 4
The two numbers are 4 and -1.

tan0 + 1=0
write your answer in radians in terms of pi
Answer:
Our range is within [0,2π]
We cant exceed that.
tan∆ + 1=0
tan∆= -1
∆=tan-¹(-1)
∆=-45°
Now it has 3 Solutions within the given interval
-45° x π/180 = -π/4
So For the second quadrant... 180-∆ = 180-45 =135°
It is true for tan(135) Which is also equal to -1
135xπ/180 = 3π/4
then
360-45 = 315
This is also true because tan(315)=-1
315° x π/180 = 7π/4
This is where we stop so we dont exceed the given range.

Which equation shows that the Pythagorean identity is true for 0 = 360°?
Select the equation that is in the form sin20 + cos20 = 1.
A. (-1)² +02 = 1
B. 02 + 12 =1
O c. 12 + 02 = 1
D. 02 + (−1)2 = 1
If the measure of an angle is 360°, then the value of sin²θ + cos²θ = 1 will be 0² + 1² = 1. Then the correct option is B.
What is a Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|² = |AB|² + |BC|²
where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).
The equation is given below.
sin²θ + cos²θ = 1
If the angle is 360°. Then the equation will be
sin²360° + cos²360° = 1
0² + 1² = 1
Then the correct equation is B.

What quantity of 75 per cent acid solution must be mixed with a 30 per cent solution to produce 1080 mL of a 50 per cent solution?
Answer: 480 mL, 600 mL
Step-by-step explanation:
Given
The concentration of the first acid is 75%
The concentration of the second acid is 30%
The final mixture has a concentration of 50%
The final volume is 1080 mL
Suppose x and y be the volume of the first and second acid
[tex]\therefore x+y=1080\quad \ldots(i)\\0.75x+0.3y=0.5\times 1080\quad \ldots(ii)[/tex]
Solving the above equations we get
[tex]x=480,y=600[/tex]
So, the quantity of the first acid is 480 mL and 600 mL for the second mixture.

rani finishes painting her room at 4:17 p.m. She painted for 42 minutes
Answer:
Uh this question Im not sure what you're asking, but if it's when it started, than the answer is 3:35
Step-by-step explanation:
Rani started painting her room at 3:35 p.m. (or 15:35 in 24-hour format).
To determine the time at which Rani started painting her room, we can subtract the duration of time she painted (42 minutes) from the time she finished (4:17 p.m.).
1. Convert the time to a consistent format: Since Rani finished painting at 4:17 p.m., we can represent this as 16:17 in 24-hour format.
2. Subtract the duration of time: Subtracting 42 minutes from 16:17 gives us 15:35.
In a simple manner:
First, we convert the time to a 24-hour format for easier calculation.
4:17 p.m. is equivalent to 16:17 in the 24-hour format.
Now, we subtract 42 minutes from 16:17:
16:17 - 42 minutes = 15:35
Therefore, Rani started painting at 3:35 p.m.

A rectangle has an area of 226.1 square miles and a base of 13.3 miles. What is the height?
Answer:
The width (in our case it is the height) of the rectangle equals 17 miles
Step-by-step explanation:
In order to solve this, we need to know the following...
Area of a rectangle = Length x Width
(in our case based on what you said length is the base and width is the height)
Now we just change the formula to our needs and get that...
Width = Area of the rectangle / Length
And so we get...
Width = Area of the rectangle / Length
Width = 226.1 / 13.3
Width = 17 miles
