Joe uses 16 pounds of fertilizer in his three gardens. He uses 3/8 of the fertilizer in his first garden and 1/4 of the fertiliz

enot [183]

Answer: The fraction of the fertilizer is left = $\dfrac38.$

Step-by-step explanation:

Given: Fraction of fertilizer used in first garden = $\dfrac38$

Fraction of fertilizer used in second garden = $\dfrac14$

Fraction of fertilizer used in third garden = 1- (Fraction of fertilizer used in first garden)-(Fraction of fertilizer used in second garden)

= $1-\dfrac38-\dfrac14$

$=\dfrac{8-3-2}{8}\\\\=\dfrac{3}{8}$

Hence, the fraction of the fertilizer is left = $\dfrac38.$

The Maplewood symphony orchestra sold 146 tickets and collected a total of $1036 in ticket sales. admission was five dollars for

Gnom [1K]

102 adult tickets were sold.

Step-by-step explanation:

Let,

Adult tickets = x

Children tickets = y

According to given statement;

x+y=146 Eqn 1

8x+5y=1036 Eqn 2

$Multiplying\ Eqn\ 1\ by\ 5\\5(x+y=146)\\5x+5y=730\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(8x+5y)-(5x-5y)=1036-730\\8x+5y-5x-5y=306\\3x=306\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{306}{3}\\x=102\\$

102 adult tickets were sold.

Hi can someone please explain how to do this please?

Answer:

(a) an = 2n -1

(b) an = n(n +1)/2

(c) an = n^2

Step-by-step explanation:

(a) The odd numbers are an arithmetic sequence with first term 1 and common difference 2. The general term is ...

an = a1 +d(n -1)

an = 1 + 2(n -1)

an = 2n -1

__

(b) The triangular numbers are a quadratic sequence with first term 1, first first difference 2, and second differences 1.

The first few terms and differences are ...

sequence: 1, 3, 6, 10, 15, 21, 28, ... (a1 = 1)

first diff: . . . 2, 3, 4, 5, 6, 7, ... (d1 = 2)

2nd diff: . . . . 1, 1, 1, 1, 1, ... (d2 = 1)

There is a sort of general formula* that can make use of these numbers to give the general term of the sequence:

an = a1 +(n -1)(d1 +(n -2)/2(d2))

For the values we have, this gives our general term as ...

an = 1 + (n -1)(2 +(n -2)/2(1))

an = n(n +1)/2

__

(c) The general term in the sequence of square numbers is simply the square of the term number:

an = n²

_____

* There are a number of other ways to get to the general formula for triangle numbers. You can search for it, since it is well-known. You can use a quadratic regression tool on the sequence of numbers. You can develop a system of equations to find the coefficients of the quadratic equation.

The general formula given can be used to find polynomial sequences of any degree. Coefficients at successive layers in the formula are of the form (n -k)/k. The first term in parentheses following that is the first k-th difference.

I need help i'm about to cry lol

grigory [225]

Answer and Step-by-step explanation:

The answer is the last answer choice.

g(x) = $-(x + 2)^2 + 1$

We don't even have to look at the numbers to tell that this is the correct answer. We look at what is being placed there.

The equation for a transformed function is:

f(x) = $a(x-h)^2 + k$

a determines the scale of the graph and whether the graph opens up or down.

h determines whether the graph shifts left or right.

k determines whether the graph shifts up or down.

We see that there is a -1 for a, which means the graph will be facing downwards. We see a 2 for where h is, but it really is a -2, and when it becomes a positive after simplifying, the graph will shift to the left.

k is a positive 1, so the graph will be shifted up 1 unit.

Thus, the answer is the last answer choice.
