need help with these questions
Step-by-step explanation:
these are both quadratic curves, parabolas, and factorization means to express the 2 terms as multiplication with each other, so that the result would be the simplified function. in other words : find the two factor terms that make the whole function.
the advantage of factorization is to see the 2 solutions for y=0 right away.
the general form is
y = (x + a)(x + b)
and the y=0 solutions are then simply x = -a and x = -b.
in example 3 we have 2 different y=0 solutions, seemingly at x = 1 and x = 5.
that makes the factorization :
y = (x - 1)(x - 5)
when x becomes one of these values, the corresponding factor becomes 0 and therefore y becomes 0 too.
in example 4 we have only one y=0 solution (or so it seems; in fact there are still formally 2 solutions, they are just equal).
it is seemingly at x = -2.
since both solutions are equal, we have also two equal factors.
that makes the factorization
y = (x + 2)(x + 2) = (x + 2)²

Beth had k dollars. She spent 8 dollars on a bag and the rest of the money on 4 notepads. Find the cost of each notepad in terms of k.
Answer:
Price of a notepad in terms of k ⇒ (k - 8)/4
Step-by-step explanation:
Let the price of a notepad be n.
8 + 4n = k
In order to get the answer, we've to make n as the subject of the above equation.
8 + 4n = k
4n = k - 8
n = (k - 8) / 4

Answer:
So for Shop A 10, a pack of 10 pens is going to be 2.30. To get to 70 pens we must multiply
7x2.30
=$16.10
For Shop B you must first divide
70 divided by 5 = 14 packs of pens in total, divide 14 by 2 because half of the packs will be half off.
so, 7x1.60
=$11.20- then divide 1.60 by 2 = $0.80,
then multiply by 7
=$5.60, then add the the two numbers for Shop B,
$11.20 + $5.60= 16.80
Step-by-step explanation:
So if you buy pens from Shop A you will spend $16.10, If your buying pens for Shop B you will spend $16.80
The difference from buying pens from Shop A and Shop B would be $0.70

Evaluate ∫ y2dx + x dy along the following paths. (a) C = C1 is the line segment from (-13, -7) to (0, 6) (b) C = C2 is the arc of the parabola x = 36 - y2 from (-13, -7) to (0, 6).
a. Parameterize C₁ by
[tex](x(t),y(t)) = (1-t)(-13,-7) + t(0,6) = (-13+13t,-7+13t)[/tex]
with 0 ≤ t ≤ 1. Then both dx = 13 dt and dy = 13 dt, so that the line integral along C₁ is
[tex]\displaystyle \int_C y^2\,dx + x\,dy = \int_0^1 (-7+13t)^2(13\, dt) + (-13+13t)(13\,dt)[/tex]
[tex]\displaystyle \int_C y^2\,dx + x\,dy = 13 \int_0^1 (169t^2 - 169t + 36) \, dt[/tex]
[tex]\displaystyle \int_C y^2\,dx + x\,dy = 13 \left(\frac{169}3-\frac{169}2+36\right) = \boxed{\frac{611}6}[/tex]
b. Parameterize C₂ by
[tex](x(t),y(t)) = (36-t^2,t)[/tex]
with -7 ≤ t ≤ 6. Then dx = -2t dt and dy = dt, so the line integral is
[tex]\displaystyle \int_C y^2\,dx + x\,dy = \int_{-7}^6 t^2(-2t\,dt) + (36-t^2)\,dt[/tex]
[tex]\displaystyle \int_C y^2\,dx + x\,dy = \int_{-7}^6 (36-t^2-2t^3) \, dt[/tex]
[tex]\displaystyle \int_C y^2\,dx + x\,dy = \left(36\cdot6-\frac{6^3}3-\frac{6^4}2\right) - \left(36\cdot(-7)-\frac{(-7)^3}3-\frac{(-7)^4}2\right) = \boxed{\frac{5005}6}[/tex]

Mrs. Penn charges $10.00 an hour on top of a $5.00 flat fee for tutoring. Mrs. Smith charges $14.00 an hour with no flat fee. Write and solve an equation to find how many hours T takes for Mrs. Penn and Mrs. Smith to get paid the same amount.
Answer:
1.25 Hours (1 hour & 15 minutes)
Step-by-step explanation:
14x = 5 + 10x
Subtract 10x from both sides
4x = 5
Divide by 4 on both sides
x = 1.25
It will take 1 hour and 15 minutes (1.25 hours) for Mrs. Penn and Mrs. Smith to be paid the same amount.

2.57×10-1= 24.7
Answer:
2.57x10^4 is 100,000 Greater that 2.57x10^-1
Step-by-step explanation:
2.57x10^4 has a power by 4 which means
10^4 = 10,000
and 2.57x10^-1 has a power by -1 which means
10^-1 = 0,1
therefore 2.57x10^4 is 100,000 Greater that 2.57x10^-1

One more dilation problem
Write the rule to describe each transformation??
Answer:
it is strech
Step-by-step explanation:
The dilation of triangle QRS is stretched by scale factor 1/2.5.
From the Figure,
The coordinates of S(-1, 0), R(-1, 1) and Q(2, 0)
and, the coordinates of S' (-2.5, 0), R'(-2.5, 2.5) and Q'(5, 0).
Now, the scale factor is
= side of QRS / side of Q'R'S'
As, side of QR = 3 unit and side of Q'R' = 7.5 unit.
So, the scale factor is
= 3 /7.5
= 1 / 2.5
Thus, the dilation is stretched by scale factor 1/2.5.
