But then go put some cold water on your face, and think about what your life would be like if you weren't depressed. then i want you to get some paper and write down what you think it would take for you to get to that place. now when you feel this way again use that paper as a reference.

Answer:

Step-by-step explanation:

For a lot of these summation problems it is worthwhile to learn to use a calculator or spreadsheet to do the arithmetic. Here, the ends of the intervals are 1 unit apart, so we only need to evaluate the function for integer values of x.

Almost any of these numerical integration methods involve some sort of weighted sum. For trapezoidal integration, the weights of all of the middle function values are 1. The weights of the first and last function values are 1/2. The weighted sum is multiplied by the interval width, which is 1 for this problem.

The area by trapezoidal integration is about 1.649 square units.

In the attached, we have shown the calculation both by computing the area of each trapezoid (f1 does that), and by creating the weighted sum of function values.

9. Use the graph of each polynomial function to find the factored form of the related polynomial.
Assume the polynomial has no constant factor.
A.
What are the zeros of this function? (2 points)
what is the factorization of the polynomial

Answers

Answer:

A) the zeros are; x = -2 and x = 4

B) y = (x + 2)(x - 4)

Step-by-step explanation:

A) The zeros are the values of x where the graph curve crosses the x-axis.

Looking at the graph, the curve crosses the x-axis at x = -2 and x = 4

Thus, the zeros are; x = -2 and x = 4

B) Factorization of the polynomial means that we transform the zeros into the polynomial.

Thus, we have; y = (x + 2)(x - 4)

So when y is zero, x = - 2 or 4 as earlier derived.

what does b equal?
-15 b - 25 = -2

Answers

Answer:

b = - [tex]\frac{23}{15}[/tex]

Step-by-step explanation:

- 15b - 25 = - 2

- 15b - 25 + 25 = - 2 + 25

- 15b = 23

- 15b ÷ - 15 = 23 ÷ - 15

b = - [tex]\frac{23}{15}[/tex]

Charla works at a clothing store. Her pay is calculated using the formula p = 550 +0.15t, where p is her total pay, d is the number of days
she worked, and is the amount of her total sales.
What were her total sales if her pay was $785 and she worked 5 days?

Answers

The total sales if her pay was $785, and she worked 5 days will be $1,000.

The correct equation is p = 55d + 0.15t.

What is simplification?

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

Charla works at a clothing store.

Her pay is calculated using the formula

p = 55d + 0.15t

where p is her total pay, d is the number of days she worked, and t is the amount of her total sales.

Then the total sales if her pay was $785, and she worked 5 days will be

785 = 55 × 5 + 0.15 t

0.15t = 510

t = $1,000

Remark

An inverse relationship is one of the variables is in the denominator of a fraction and the other is given on the other side of the equal sign. It sounds more complicated than it is. Here's that long sentence broken down to 3 letters.

f = k/w

Formula

f = k/w

f is the frequency

k is the speed of sound

w is the wavelength

Givens

f = 880 Hz

k = 340.2 m/s

w = ?

Solution

f = k/w

880 = 340.2/ w Multiply both sides by w

880*w = w* 340.2 /w

880*w = 340.2 Divide by 880

w = 340.2/880

w = 0.387 m

12 divided by 1 1/5 = ?

IN lowest TERM

Answers

Answer:

12 divided by 1 1/5 = 60/11 in lowest term

I hope this helps you.

Step-by-step explanation:

Simplify the expression.

After converting mixed fraction into improper fractions,

12 divided by 1 1/5 = 10

Here we can write "12 divided by 1 1/5 " as,

12 ÷ [tex]1\frac{1}{5}[/tex]

Here [tex]1\frac{1}{5}[/tex] is in the form of a mixed fraction.

First of all we have to convert it into improper fraction,

Therefore multiplying 1 with denominator then add it to the numerator as,

[tex]1\frac{1}{5}[/tex] = (1x5 + 1)/5

= 6/5

Now we can write

12 ÷ [tex]1\frac{1}{5}[/tex] = 12 ÷ 6/5

= 12/(6/5)

= 12 x(5/6)

= (12/6)x5

= 2x5

= 10

Hence,

12 divided by 1 1/5 = 10.
