Insight number 2: to evaluate the limit of a:
1. Rational function: you can factorize and cancel out what you can
2. Radicals (subtractions of square roots): multiply and divide by the
conjugate. For example:
Vx2 + 1 - x
x? +1 - x2
x2 +1-x=
(V x2 +1 + x)
Vx2 + 1 + x
V.x2 + 1 + x
1
Vx2 +1 + x
3. Trigonometric functions: try to connect your limit with important
sin (x)
trigonometric limits like limx40 = 1
If you are stuck with a trig limit, express all the trig functions in terms
of sine and cosine.
4. If you are composing continuous functions, you can pass the limit
inside the external function: Cimz-a f(g(x)) = f(lim,-a 9(x))

Marcia is at a store with a 20% off sale. She also has a coupon for an additional 10% off the sale price.
Prove or disprove the following statement: A 20% discount on the original price of an item, followed by the use of a 10% off coupon, results in a total discount of 30%.
I wil brainly anyone who answers this right with explination
Answer:
False
Step-by-step explanation:
I will use an example here:
Original price of a pc is $799
you use your 20% off coupon which will bring it down:
799 decrease 20% =
799 × (1 - 20%) = 799 × (1 - 0.2) = 639.2
then you use your 10% off coupon:
639.2 decrease 10% =
639.2 × (1 - 10%) = 639.2 × (1 - 0.1) = 575.28
our final price doing them separately is $575.28
while doing it in one step by subtracting 30%:
799 decrease 30% =
799 × (1 - 30%) = 799 × (1 - 0.3) = 559.3
our price by doing it with a 30% discount is $559.30

If a1=1 and an+1=ann+2 for n≥1, determine a1,a2,a3, and a4
Answer:
a1 =1
a2= 1/3
a3= 1/12
a4 = 1/60
Step-by-step explanation:
a(n+1) = an/(n+2)
if n=1
a(1+1)= a1/(1+2)
a2= a1/3
a2= 1/3
if n=2
a(2+1)= a2/(2+2)
a3= a2/4 = a2 × 1/4
a3= 1/3 × 1/4 = 1/12
if n=3
a(3+1)= a3/(3+2)
a4= a3/5 = a3 × 1/5
a4= 1/12 × 1/5 = 1/60
The value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] for a given expression [tex]\rm a_{n+1} = {\frac {a_{n}} {n+2}[/tex] is 1, 1/3, 1/12, and 1/60.
We have given [tex]\rm a_{1} =1[/tex] and [tex]\rm a_{n+1} = {\frac {a_{n}} {n+2}[/tex] for n≥1 we need to determine the value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] .
How do you solve for n terms?To solve for n terms, we will substitute the value of n = 1,2,3,4 and so on sequence-wise in the given expression.
if n = 1
[tex]\rm a_{1+1} = {\frac {a_{1}} {1+2}[/tex]
[tex]\rm a_{2} = {\frac {a_{1}} {3}}\\\rm a_{2} = {\frac{1} {3}[/tex]
if n = 2
[tex]\rm a_{2+1} = {\frac {a_{2}} {2+2}}\\\rm a_{3} = {\frac {1/3} {4}}\\\rm a_{3} = 1/12[/tex]
if n = 3
[tex]\rm a_{3+1} = {\frac {a_{3}} {3+2}}\\\rm a_{4} = {\frac {a_{3}} {5}}\\\rm a_{4} = 1/12 \times 1/5\\\rm a_{4} = 1/60[/tex]
So, the value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] is 1, 1/3, 1/12, and 1/60.

In a survey of 1.400 people who owned a certain type of car, 980 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
Percent of people satisfied with the car = 70%
Step-by-step explanation:
Given:
Total number of people survey = 1,400
Number of people satisfied with the car = 980
Find:
Percent of people satisfied with the car
Computation:
Percent of people satisfied with the car = [Number of people satisfied with the car / Total number of people survey]100
Percent of people satisfied with the car = [980 / 1400]100
Percent of people satisfied with the car = 70%

Answer:y = 10.5
Step-by-step explanation:
First, assign a variable to each unknown value.
Let:
x = cost of the pepperoni pizza
y = cost of the plain pizza
Next, set up equations based on the word problem. We then have the following equations:
(1) 3x + 2y = 58.50
(2) 2x + 4y = 67
Equation (1) comes from the statement: "Jack paid 58.50 for 3 pepperonies and 2 plain pizzas". Equation (2), on the other hand, translates the statement: "Jill paid 67 for 2 pepperonies and 4 plain pizzas".
To solve for two unknown variables given two independent equations, eliminate one variable first. That is, multiply equation (1) to -2.
-2[3x + 2y = 58.50]
-6x -4y = -117
Then add this to equation (2):
-6x -4y = -117
2x + 4y = 67
-------------------
-4x = -50
x = -50/-4 = 12.5
To solve for y, we use equation (2) and substitute the value of x which has been solved already.
2(12.5) + 4y = 67
y = 10.5
To summarize, they paid $12.50 for the pepperoni pizza while they paid $10.50 for the plain pizza.
