Step-by-step explanation:
The school that Ted goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 7 adult tickets and 8 child tickets for a total of $168. The school took in $294 on the second day by selling 14 adult tickets and 13 child tickets. Find the price of an adult ticket AND the price of a child ticket.
Answer:
Adult= $24
child= $21
Step-by-step explanation:
first let's create an equation for each one.
Day 1: 7x+8y=168
day 2: 14x+13y=294
By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.
x-int.= (24,0)
y-int.=(0,21)

A glacier in Alaska moves about 29.2 meters a day.
About how much farther will it move in 1,000 days than it will move in 100 days?
Answer:
29,100
Step-by-step explanation:
29.1 × 10 = 291
29.1 × 100 = 2,910
29.1 × 1000 = 29,100
what are the missing angles?
Answer:
To determine to measure of the unknown angle
Step-by-step explanation:
If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2
"To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2."

Answer:
y'' = 18x(x³ + 8)⁴(17x³ + 16)
General Formulas and Concepts:
Calculus
Derivative Notation dy/dx
Derivative of a constant is 0.
Basic Power Rule:
f(x) = cxⁿ f’(x) = c·nxⁿ⁻¹Chain Rule: [tex]\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)[/tex]
Product Rule: [tex]\frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)[/tex]
Step-by-step explanation:
Step 1: Define
y = (x³ + 8)⁶
Step 2: Find 1st Derivative (dy/dx)
Chain Rule [Basic Power]: y' = 6(x³ + 8)⁶⁻¹ · (3x³⁻¹ + 0)Simplify: y' = 6(x³ + 8)⁵ · 3x²Multiply: y' = 18x²(x³ + 8)⁵Step 3: Find 2nd Derivative (d²y/dx²)
Product Rule [Chain/Basic Power]: y'' = 2 · 18x²⁻¹ · (x³ + 8)⁵ + 18x² · 5(x³ + 8)⁵⁻¹ · (3x³⁻¹ + 0)Simplify: y'' = 36x(x³ + 8)⁵ + 90x²(x³ + 8)⁴ · 3x²Multiply: y'' = 36x(x³ + 8)⁵ + 270x⁴(x³ + 8)⁴Factor: y'' = 6x(x³ + 8)⁴[6(x³ + 8) + 45x³]Distribute: y'' = 6x(x³ + 8)⁴[6x³ + 48 + 45x³]Combine like terms: y'' = 6x(x³ + 8)⁴[51x³ + 48]Factor: y'' = 6x(x³ + 8)⁴ · 3(17x³ + 16)Multiply: y'' = 18x(x³ + 8)⁴(17x³ + 16)Answer:
[tex]\frac{d^{2}y}{dx^{2}} = 180x.(x^{3} +8)^{4}[/tex]
Step-by-step explanation:
This question requires use of the chain rule:
[tex]y = (x^{3} + 8)^{6}[/tex]
Let:
[tex]u = x^{3} + 8[/tex]
Then:
[tex]y = u^{6}[/tex]
And:
[tex]\frac{dy}{dx} = \frac{dy}{du}. \frac{du}{dx}\\\\\frac{d^{2}y}{dx^{2} } = \frac{d^{2}y}{du^{2}}. \frac{d^{2}u}{dx^{2}}\\\\\frac{dy}{du} = 6u^{5}\\\\\frac{d^{2}y}{du^{2}} = 30u^{4}\\\\\frac{du}{dx} = 3x^{2}\\\\\frac{d^{2}u}{dx^{2}} = 6x[/tex]
So:
[tex]\frac{dy}{dx} = 6u^{5}.3x^{2}\\\\\frac{dy}{dx} = 18u^{5}x^{2}\\\\[/tex]
And:
[tex]\frac{d^{2}y}{dx^{2}} = 30u^{4}.6x\\\\\frac{d^{2}y}{dx^{2}} = 180u^{4}x[/tex]
Finally, substitute u for its equivalent expression in x:
[tex]\frac{d^{2}y}{dx^{2}} = 180x.(x^{3} +8)^{4}[/tex]
Steph owed her mother $84. She earned $6.25 for raking the leaves each week and 3.25 for unloading the dishwasher each week, how many weeks would it take her to pay her mother back?
Answer: About 10 weeks
Step-by-step explanation:
Step 1- 6.25 + 3.25 = 9.50
Step 2- 84 - 9.50 = 74.50
Step 3- 74.50 divide by 7
Step 4- Answer 10. 64285 and so on
Which expression is equivalent to
Square root of 80 ?
Answer:
4i√5
Step-by-step explanation:
Find the solution to the equation.
30=−5n+16+3n
Enter only a number. Do NOT enter an equation. If the number is not an integer, enter it as a fraction in simplest form. If there is no solution, “no solution” should be entered.
Answer:
-7
Step-by-step explanation:
30-16= -5n +3n
14 = -2n
multiplying both by half,u have -
7 = -n
multiply both by -1
7 = n

Answer:D because you divide it bu a common factor
Step-by-step explanation:
determine if the lines are parallel perpendicular or neither y=-7 and x=2
Answer:
Perpendicular
Step-by-step explanation:
Because the two lines don't have a "b" value in the equation y=mx+b, we know that both these lines are straight lines either horizontal or vertical. So, if we were to graph these, they would intersect and creat 4 90º angles, making it perpendicular (see graph as well)
