Step-by-step explanation:

$(x {}^{4} - x) {}^{4} - ( {x}^{4} - x)$

$x {}^{16} + 4( {x}^{12} ) - x + 6( {x}^{8} )( {x}^{2} ) + 4( {x}^{4} )( - {x}^{3} ) + {x}^{4} -( {x}^{4} - x)$

${x}^{16} - 4 {x}^{13} + 6 {x}^{10} - 4 {x}^{7} + {x}^{4} - {x}^{4} + x$

${x}^{16} - 4x {}^{13} + 6 {x}^{10} - 4 {x}^{7} + x$

A laboratory technician needs to make a 63-liter batch of a 20% acid solution How can the laboratory technician combine a batch

Gre4nikov [31]

Let x be the volume (liters) of pure (at 100%) acid needed
Let y be the volume (liters) of the other acid (at 10%) needed
The final solution will be:
a) x+ y = 63 liters, AND their respective concentration in acid: is
100% x & 10% :y that will generate 63 liters at 20%
b) x +0.1 y = 63x 0.2 = 12.6

Let's solve this system of 2 equations:

x + y =63
x + 0.1 y = 12.6

Solving it will give you:

x= 7 liters at 100%
y = 56 liters at 10%

a 9ft ladder is placed 4.5 feet from the base of a wall. How high up will the ladder reach? Round to the nearest hundredth.

spin [16.1K]

Answer:

$\huge\boxed{7.79 \ \text{feet}}$

Step-by-step explanation:

We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.

This can be represented as a triangle, where x is the unknown side.

| \

x | \ 9

| \

|_____\

4.5

We can use The Pythagorean Theorem to find the value of x. The theorem states that $a^2+b^2=c^2$ , where a and b are the lengths of the legs and c is the length of the hypotenuse.

However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.

$a^2 + 4.5^2 = 9^2\\\\a^2 + 20.25 = 81\\\\a^2 = 60.75\\\\a \approx 7.79$

Hope this helped!
