What is the point-slope form of a line with slope-5 that contains the point
(2, -1)?
Answer:
point slope form
y-y1=m(x-x1) where
m=slope and you are given a point (x1,y1)
slope=-5
point is (2,-1)
x1=2
y1=-1
m=-5
so
y-(-1)=-5(x-2)
y+1=-5(x-2) is answer

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.
need help for an assignment please and thank you.
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]

a set contains the numbers 0,6,12, and 15 Two different numbers are selected randomly from this set. What is the probability that the sum is greater than 12? What is the probabilty the product is 72?
The probability that the sum is greater than 12 is [tex]\frac{2}{3}[/tex]. The probability the product is 72 is [tex]\frac{1}{6}[/tex].
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes
The outcomes that the sum is greater than 12
6 and 12, 6 and 15, 12 and 15, 0 and 15
So the probability that the sum is greater than 12 is
= [tex]\frac{4}{C^{2} _{4} }[/tex]
= [tex]\frac{4}{6}[/tex]
= [tex]\frac{2}{3}[/tex]
The outcomes that the product is 72: 6 and 12
So the probability is
= [tex]\frac{1}{C^{2} _{4} }[/tex]
= [tex]\frac{1}{6}[/tex]
Hence, the probability that the sum is greater than 12 is [tex]\frac{2}{3}[/tex]. The probability the product is 72 is [tex]\frac{1}{6}[/tex].

Answer:
A. 6x + 4
B. 22 cm
Step-by-step explanation:
The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.
When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.

Find the average rate of change for f(x)= x to the second power+ 7x+10 from x= 0 to x= 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]
We plug in values to get:
[tex](28-10)/(2-0)[/tex]

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)

What quadrant does Cos A < 0, Tan A < 0
Answer:
Cos A < 0 in the 3rd and 4th quadrants
Tan A < 0 in the 2nd and 4th quadrants
Step-by-step explanation:
In trigonometry, we make use of the ACTS initials to get which quadrant has it's sine, cosine or tangent functions as negative or positive.
In quadrant 1, it is denoted by A meaning All of sine, cosine and tangent functions are positive
In quadrant 2, it is denoted by C to mean that only cosine is positive i.e. greater than 0.
In quadrant 3,it is denoted by T to mean that only cosine is positive i.e. greater than 0.
In quadrant 4, it is denoted by S to mean that only sine is positive i.e. greater than 0.
Thus, comparing all above with the question, we can say that;
Cos A < 0 in the 3rd and 4th quadrants
Tan A < 0 in the 2nd and 4th quadrants

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.
