Answer:
We know that the derivative of sec x is sec x tan x. Thus, the integral of sec x tan x is sec x. i.e., ∫ sec x tan x dx = sec x + C.
Step-by-step explanation:
The standard trick used to integrate secx is to multiply the integrand by 1 = sec x+tan x. sec x+tan x. and then substitute y = secx + tanx, dy = (secxtanx + sec2 x) dx. ∫ secx dx = ∫ secx sec x+tan x).
Find an equation of the line parallel to y=2x+1 and that passes through the point (5,1)
Answer:
y = 2x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes , then
y = 2x + c ← is the partial equation
To find c substitute (5, 1 ) into the partial equation
1 = 10 + c ⇒ c = 1 - 10 = - 9
y = 2x - 9 ← equation of parallel line

The state fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 14 vans and 6 buses with 564 students. High School B rented and filled 4 vans and 6 buses with 414 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
Answer:
No of student can be found using x+y=total
X+y=total
Concept
Step-by-step explanation:
Let vans be x
Let bas be y

Answer: [tex]2x^{2} + 5x -3[/tex]
Step-by-step explanation:
Find the quotient of [tex]\frac{16x^4+40x^3-24x^2}{8x^2}[/tex]
Step 1: Break down the polynomial equation
[tex]\frac{16x^4}{8x^2}[/tex] + [tex]\frac{40x^3}{8x^2}[/tex] - [tex]\frac{24x^2}{8x^2}[/tex]
Step 2: Divide each piece by dividing the coeffients and subtracting the variables.
16 ÷ 8 = 2
[tex]x^{4}[/tex] - [tex]x^{2}[/tex] = [tex]x^{2}[/tex] → 2[tex]x^{2}[/tex]
40 ÷ 8 = 5
[tex]x^{3}[/tex] - [tex]x^{2}[/tex] = [tex]x[/tex] → 5[tex]x[/tex]
- 24 ÷ 8 = - 3
[tex]x^{2}[/tex] - [tex]x^{2}[/tex] = 1 → - 3
Step 3: Put the polynomial together
2[tex]x^{2}[/tex] + 5[tex]x[/tex] - 3
The second term of an arithmetic sequence is –5, and the third term is –20. What is the first term?
Answer:
a₁ = 10
Step-by-step explanation:
The common difference d is calculated as
d = a₃ - a₂ = - 20 - (- 5) = - 20 + 5 = - 15
Then
a₂ - a₁ = d , that is
- 5 - a₁ = - 15 ( add 5 to both sides )
- a₁ = - 10 ( multiply both sides by - 1 )
a₁ = 10

Solve -3(x-2)=2(x-7) and write a reason for each step
Answer:
4=x
Step-by-step explanation:
-3(x-2)=2(x-7)
Distribute -3 and 2.
-3x+6=2x-14
Add 3x to both sides of the equation.
6=5x-14
Add 14 to both sides of the equation.
20=5x
Divide 5 from both sides of the equation.
4=x
Hope this helps :)
Answer:
x=5
Step-by-step explanation:
Our equation is
-3(x-2)=2(x-7)
First we will distribute -3 and 2, because in math when we have a number being multiplied into parenthesis we multiply both things inside of it
Our equation is now
-3x+6=2x-14
Next we subtract 6 from both sides because we want x to be on only one side
-3x=2x-20
Next we subtract 2x from both sides because we want x to equal something exactly
-5x=-20
Now we divide -5 from both sides because we only want x
x=5

What is the vertex and p-value of this parabola?
Answer:
vertex: (-7, 5)p = 2Step-by-step explanation:
The vertex is halfway between the focus and the directrix:
((-7, 7) +(-7, 3))/2 = (-14, 10)/2 = (-7, 5) . . . . vertex coordinates
The value of p is the distance from the focus to the vertex:
7 -5 = 2 = p
In vertex form, the equation of the parabola is ...
y = 1/(4p)(x -h)^2 +k . . . . . . vertex (h, k)
y = 1/8(x +7)^2 +5
A company rents out 16 food booths and 20 game booths at the county fair. The fee for a food booth is $200 plus $9 per day. The fee for a game booth is $95 plus $6 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
20(95+6d)+16(200+9d)
Step-by-step explanation:
I'm not so sure about this question since I'm also learning about algebra right now.
But we know there's 20 game booths that costs 95$ and 6$ for d days
if so first we need to know how much 1 booth cost, which is $95 plus $6 per day and as an expression: 95+6d. Then there's 20 booths so we multiply it, and we need to add parentheses according to the priority rule. So it should be 20(95+6d)?
then food booths are 16(200+9d)
then we add them so
20(95+6d)+16(200+9d)
