Y=-0.05x^2+4.5x-6.5 pls help to solve

1 answer:

6 0

Following with the extra hint that x = 82.03 m

There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:

Plug x = 82.03

=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m

Please take the time and understand the answer instead of just looking at the final result.

Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>

Answer:

Isn't that just soild liquid and gas atoms?

The image is showing how the atoms change depending on which state of matter it is, so if it is a soild the atoms would be really compacted as it moves slower, if it's a liquid then it's more looser than a soild, but more compacted than a gas, and a gas is just moving a lot and has a lot more space.

^^ That would be the answer if you on the states of matter or something like that unit.

Answer:

314 cm²

Step-by-step explanation:

To find the area of a circle, use the formula A = πr² by substituting r = 10.

A = πr² = π10² = 314 cm²

Planes S and R both intersect plane T .

neonofarm [45]

<h2>[A] Plane S contains points B and E.</h2>

False

As indicated in Figure A below, Plane S contains only point B (remarked in red). Point E (remarked in blue) lies on plane R.

<h2>[B] The line containing points A and B lies entirely in plane T.</h2>

True

As indicated in Figure B below, the line containing points A and B lies entirely in plane T. That line has been remarked in red and it is obvious that lies on plane T.

<h2>[C] Line v intersects lines x and y at the same point.</h2>

False

As indicated in Figure C below, line v intersects lines x and y, but line x in intersected at point B while line y (remarked in red) is intersected at point A (remarked in blue), and they are two different points, not the same.

<h2>[D] Line z intersects plane S at point C.</h2>

True

As indicated in Figure D below, line z that has been remarked in yellow, intersects plane S at point C that has been remarked in blue.

<h2>[E] Planes R and T intersect at line y.</h2>

True

As indicated in Figure E below, planes R and T intersect at line y. The line of intersection has been remarked in red.

You have to combine like terms (terms that have the same variable(x,y....) and power/exponent)²³

(4x³ - 4 + 7x) - (2x³ - x - 8) Distribute -1 into (2x³ - x - 8)

(4x³ - 4 + 7x) + (-)2x³ - (-)x - (-)8 (two negative signs cancel each other out and become positive)

(4x³ - 4 + 7x) - 2x³ + x + 8 Now combine like terms

4x³ - 2x³ + 7x + x - 4 + 8 (I rearranged for the like terms to be next to each other)

2x³ + 8x + 4 It is equivalent to B

$(-3x^2+x^4+x)+(2x^4-7+4x)$ Combine like terms

$-3x^2+x^4+2x^4+x+4x-7$ (I rearranged for the like terms to be next to each other)

$-3x^2+3x^4+5x-7$ It is equivalent to D

(x² - 2x)(2x + 3) Distribute x² into (2x + 3) and distribute -2x into (2x + 3)

(x²)2x + (x²)3 + (-2x)2x + (-2x)3

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together

2x³ + 3x² - 4x² - 6x Combine like terms

2x³ - x² - 6x It is equivalent to A

[Info]

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (You can combine the exponents only if they have the same variable)

For example:

$x^{2} (x^3)=x^{(2+3)}=x^5$
