Answer:
y = -1
Step-by-step explanation:
First, you find the slope by using the slope formula and get 0. Now, choose one coordinate and plug it into the equation y = mx + b along with the slope. If you chose the first coordinate, the equation would be -1 = (0)(5) + b. After solving for b (the y-intercept) you would get -1. Lastly, you rewrite the equation as y = -1.

Answer:
m<U = 38degrees
Step-by-step explanation:
From the given diagram, <B = <U since both triangles are similar, hence;
Hence;
2y+2 = 3y-16
2y - 3y = -16 - 2
-y = -18
y = 18
Get m<U
m<U = 3y-16
m<U = 3(18) -16
m<U = 54 - 16
m<U = 38degrees

I need help answering question 1 and question 2
Answer:
Step-by-step explanation:
1. y= 1-x² is quadratic because has the variable x to the second power
y = -x² +1 has quadratic term -x², and constant term is 1
2. y= 3x-5 +4x²
a. quadratic term is 4x² because has the variable x to the second power
b. linear term is 3x because has the variable x to the power of one
c. constant term is -5 because the variable x to the power 0 so there is no x

What are the end behaviors of f(x) = (1/3)^x – 2 ?
Answer:
[tex]\lim_{x\to -\infty} f(x)=\infty,\\\lim_{x\to \infty} f(x)=2,[/tex]
Step-by-step explanation:
The end behaviors of a function simply denote where the function is headed at x approaches negative and positive infinity. In [tex]f(x)=\left(\frac{1}{3}\right)^x+2[/tex], as [tex]x[/tex] gets approaches [tex]-\infty[/tex], the function will approach [tex]y=\infty[/tex]. As [tex]x[/tex] approaches [tex]\infty[/tex], the function will approach [tex]y=2[/tex].
We can write this in the following format to denote these end behaviors:
[tex]\lim_{x\to -\infty} f(x)=\infty,\\\lim_{x\to \infty} f(x)=2,[/tex]

Answer:
circumference of a circle :
[tex]2\pi r\\[/tex] = 2 π x 6 = 12π inches
Segment MP is tangent to circle O. Find the length of the radius of circle O.
R = 10.5
Step-by-step explanation:
Using Pythagorean theorem, we can write
(OM)^2 + 10^2 = (OR + 4)^2
Since OM = OR, let's call this segment R for brevity.
R^2 + 10^2 = (R + 4)^2
R^2 + 100 = R^2 + 8R + 16
This simplifies to
8R = 84
or R = 10.5

cot(-x)*sin(x) = -cos x
help pls lol
simplify that fist answer gets brainliest and if its a bs answer it doesn't count :D
Answer:
0
Step-by-step explanation:
first you will need to know the negative angle identities, which show that cot(-x)=-cot(x), you can then simplify that to -(cos/sin) so when you multiply by sin(x), or sin(x)/1, the sines cancel out and you are left with -(cos(x)/1)*(1/1) so your equation is now -cos(x)=-cos(x), so when you add the cosines over, you get zero

Clark and his friends bought strawberry wafers for $2 per packet and chocolate wafers for $3 per packet at a carnival. They spent a total of $30 to buy a total of 14 packets of wafers of the two varieties.
Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Clark and his friends bought at the carnival. Make sure you say what each variable means! (Which one is which wafer type?)
Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer.
Answer:
Step-by-step explanation:
A. S=strawberry, C=chocolate
S+C=14 equation 1
2s+3c=30 equation 2
B. -2(s+c)=-2(14) multiply equation 1 by -2 to use elimination method
-2s+-2c=-28 modified Equation 1
2s+ 3c=30. Equation 2
C=2 add above two equations.
solve for s
s+c=14
s+2=14
s=12
Used elimination method since it was easier to add the two equations.
check answer by inputting s,c values in either equation.

24+6=30

9514 1404 393
Answer:
2s+3c=30s+c=142 chocolate12 strawberryStep-by-step explanation:
Part A:
I like to use variable names that remind me what they stand for. Here, we can use s and c for the numbers of strawberry and chocolate packets, respectively. The two equations we can write based on the problem statement are ...
2s + 3c = 30 . . . . . . . the total cost of the purchase
s + c = 14 . . . . . . . . . . the number of items purchased
__
Part B:
Ordinarily, I would use one equation for the problem. That equation can be arrived at by substituting for s using the second equation. We choose to substitute for s so the only remaining variable is the one representing the highest-value contributor to the total cost.
s = 14 -c
2(14 -c) +3c = 30 . . . . substitute for s
28 +c = 30 . . . . . . . . . simplify (notice the coefficient of c is positive)
c = 2 . . . . . . . . . . . subtract 28
s = 14 -2 = 12 . . . . find s using the above equation
They bought 2 packets of chocolate and 12 packets of strawberry wafers.
__
Explanation of choices
When the total purchase is n items and x of them are of one kind, then n-x is the number of the other kind. You don't need to write a second equation to figure that out. Hence the problem can be described by a single equation, such as the one highlighted above. Doing this lets you skip a variable definition and a couple of solution steps you don't really need.
The choice of variable as being the high-cost item ensures that its coefficient in the equation will be positive. Fewer errors are made when arithmetic is done with positive numbers. Again, recognizing that early on saves headaches down the line.
Getting to a generic solution
Note that the number we subtract (28) is the "would be" cost of all of the items purchased being the lowest-cost item (14 strawberry packets). This recognition can let you do the entire problem in your head. The difference between the actual cost and the "would be" cost is the result of replacing some number of the lowest-cost items with the higher-cost ones. The difference between total costs is divided by the difference in cost per item to find the number of the higher-cost item. That is the answer to all problems of this type. (30 -14(2))/(3-2) = 2 = the number of $3 packets.

The largest steep increase was from
to
and the second largest increase was from
Answer:
The largest steep increase was from 1965 to 1966, while the second largest was from 1967 to 1968
Step-by-step explanation:
A) 1965 to 1966; number of accidents increased from 250 to 320.
Percentage increase = (320 - 250)/250 × 100% = 28%
B) 1967 to 1968; number of accidents increased from 300 to 370.
Percentage increase = (370 - 300)/300 × 100% = 23.33%
C) 1968 to 1969; number of accidents increased from 370 to 380.
Percentage increase = (380 - 370)/370 × 100% = 2.7%
D) 1969 to 1970; number of accidents increased from 380 to 410.
Percentage increase = (410 - 380)/380 × 100% = 7.89%
Thus;
The largest steep increase was from 1965 to 1966, while the second largest was from 1967 to 1968

Are the events 'male' and 'favor independent?
Answer:
Not independent
Step-by-step explanation:
Given
See attachment for two way table
Required
Are male and favor independent?
From the table, we have:
[tex]Male = 20+15+17[/tex]
[tex]Male = 52[/tex]
[tex]Favor = 20 + 18[/tex]
[tex]Favor = 38[/tex]
[tex]Total = 20+15+17+18+12+7[/tex]
[tex]Total = 89[/tex]
Calculate P(Male)
[tex]P(Male) = \frac{Male}{Total}[/tex]
[tex]P(Male) = \frac{52}{89}[/tex]
Calculate P(Favor)
[tex]P(Favor) = \frac{Favor}{Total}[/tex]
[tex]P(Favor) = \frac{38}{89}[/tex]
Calculate P(Male and Favor)
[tex]P(Male\ and\ Favor) = \frac{Male\ and\ Favor}{Total}[/tex]
[tex]P(Male\ and\ Favor) = \frac{20}{89}[/tex]
[tex]P(Male\ and\ Favor) = 0.2247[/tex]
The events are independent is:
[tex]P(Male\ and\ Favor) =P(Male) * P(Favor)[/tex]
So, we have:
[tex]P(Male\ and\ Favor) =\frac{52}{89} * \frac{38}{89}[/tex]
[tex]P(Male\ and\ Favor) =\frac{52*38}{89*89}[/tex]
[tex]P(Male\ and\ Favor) =\frac{1976}{7921}[/tex]
[tex]P(Male\ and\ Favor) =0.2495[/tex]
By comparison:
[tex]P(Male\ and\ Favor) =0.2495[/tex] and [tex]P(Male\ and\ Favor) = 0.2247[/tex] are not equal
Hence, the events are not independent

Answer:
Step-by-step explanation:
a+b=9500 equation 1
35a+55b=432500 equation 2
a=9500-b modified equation 1 to isolate a
