What is he equation of the line passing through the points ( 2/5,19/20 ) and (1/3,11/12) in slope-intercept form?

The standard form of the expression is x⁵+ 7x⁴ + 8x² - 9x - 5.

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

To write the given expression in standard form, we need to arrange the terms in descending order of their exponents (from highest to lowest).

So we start by rearranging the given expression as:

x⁵+ 7x⁴ + 8x² - 9x - 5

Now the terms are ordered from highest to lowest exponent.

Now we need to rewrite the expression by collecting like terms and arranging the coefficients in descending order of exponent.

The standard form of the expression is:

x⁵+ 7x⁴ + 8x² - 9x - 5

Hence, the standard form of the expression is x⁵+ 7x⁴ + 8x² - 9x - 5.

Answer:

a) The jumper opens the parachute in 7.5 seconds.

b) The jumper opens the parachute in approximately 7.706 seconds.

c) There are two possible choices for the function:

Case a): [tex]Dom\{h(t)\} = [0\,s,7.5\,s][/tex], [tex]Ran\{h(t)\}=[1000\,ft,1900\,ft][/tex]

Case b): [tex]Dom\{h(t)\} = [0\,s,7.706\,s][/tex], [tex]Ran\{h(t)\}=[950\,ft,1900\,ft][/tex]

Step-by-step explanation:

Note: The equation presented in statement is incorrect. The correct formula for free fall is:

[tex]h(t)=-16\cdot t^{2}+1900[/tex] (1)

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]h[/tex] - Height above the ground, measured in feet.

a) If we know that [tex]h(t) = 1000\,ft[/tex], then the final instant of the free fall stage is:

[tex]-16\cdot t^{2}+1900 = 1000[/tex]

[tex]16\cdot t^{2} = 900[/tex]

[tex]t = 7.5\,s[/tex]

The jumper opens the parachute in 7.5 seconds.

b) How long is the jumper in free fall if the parachute opens at 950 ​ft?

If we know that [tex]h(t) = 950\,ft[/tex], then the final instant of the free fall stage is:

[tex]-16\cdot t^{2}+1900 = 950[/tex]

[tex]16\cdot t^{2} = 950[/tex]

[tex]t \approx 7.706\,s[/tex]

The jumper opens the parachute in approximately 7.706 seconds.

c) There are two possible choices for the function:

Case a): [tex]Dom\{h(t)\} = [0\,s,7.5\,s][/tex], [tex]Ran\{h(t)\}=[1000\,ft,1900\,ft][/tex]

Case b): [tex]Dom\{h(t)\} = [0\,s,7.706\,s][/tex], [tex]Ran\{h(t)\}=[950\,ft,1900\,ft][/tex]

The answer is $120.00

Options

What was the price of the bicycle when Mazie bought it?

$140.00

$149.80

$130.00

$120.00

Explanation

Multiply the price of the bike by the discount percentage

150 * 0.20 = 30

Subtract the number you just found from the original price

150 - 30 = 120

There is your answer

You could take a shortcut by doing the following

1 - 0.20 = 0.80

Then multiply the original value by the new percentage

150 * 0.80 = 120

Personally I like the first method because it makes more sense.

Step-by-step explanation:

Remark

This problem only wants to know how many ways to select 7 starting from a base of 11.

Nothing else matters. Not grades, not gender, not age, not qualifications, not order -- nothing. Just 7 out of 11.

That problem is a combination and is written as

(11)/(7)

The formula used is

11! / (7! (11 - 7)! )

11! /( 7! 4!) = 11 * 10 * 9 * 8 * 7! / (7! * 4!) The 7! s cancel out

11 * 10 * 9 * 8 / 4 * 3 * 2 * 1 = 330

Answer:

B

Step-by-step explanation:

Because you have to separate the equation. So you get [tex]\frac{2x-4}{3}[/tex]>[tex]\frac{1}{5}[/tex] And [tex]\frac{2x-4}{3}[/tex]<6

Then you have to solve for x so you get x>[tex]\frac{23}{10}[/tex] and x>11

Then you find the intersection so the answer is B

Answer:

A haircut costs $31

Coloring hair costs $93

Step-by-step explanation:

h = haircut

c = color

First equation: 1h + 2c = 217

Second equation: 2h + 1c = 155

Solve using elimination:

First, multiply both the equations so that they cancel the h's out:

First equation:

-1(2h + 1c = 155)

-2h - 1c = -155

Second equation:

2(1h + 2c = 217)

2h + 4c = 434

Then, put the equations together, and solve:

2h + 4c = 434

-2h - 1c = -155

3c = 279

c = 93

Find h:

2h + 1c = 155

2h + 1(93) = 155

2h + 93 = 155

2h = 62

h = 31
