Which number is not in scientific notation? 7 ⋅ 1024 0.8 ⋅ 103 1.09 ⋅ 10–2 1.8 ⋅ 10–5

Komok [63]

0.8 x 103 because the first number cant be less then 1 or more then 9 you would have to move the decimal to make the equation correct

5+2 root 3 / 7+4 root 3 =a-6root3

STALIN [3.7K]

Answer:

Step-by-step explanation:

$\dfrac{5+2\sqrt3}{7+4\sqrt3}\qquad\text{use}\ (a+b)(a-b)=a^2-b^2\\\\=\dfrac{5+2\sqrt3}{7+4\sqrt3}\cdot\dfrac{7-4\sqrt3}{7-4\sqrt3}=\dfrac{(5+2\sqrt3)(7-4\sqrt3)}{7^2-(4\sqrt3)^2}\qquad\text{use FOIL}\\\\=\dfrac{(5)(7)+(5)(-4\sqrt3)+(2\sqrt3)(7)+(2\sqrt3)(-4\sqrt3)}{49-4^2(\sqrt3)^2}\\\\=\dfrac{35-20\sqrt3+14\sqrt3-8(3)}{49-(16)(3)}=\dfrac{(35-24)+(-20\sqrt3+14\sqrt3)}{49-48}\\\\=\dfrac{11-6\sqrt3}{1}=11-6\sqrt3$

Eagles 95% wolves 9/10 mustangs 0.89 which team has the greatest factor of wins show your work

Marizza181 [45]

Eagles, Wolves, Mustangs because 95%=.95 and then 9/10=.9 and then .89 is less than both of those.

5. A ball is thrown straight up leaving the player's hands at at 7.5 m/s. If air resistance is ignored, how high can the ball tr

aleksley [76]

The maximum height reached is 2.87 meters

<h3>What is maximum height?</h3>

The maximum height of an object is the highest vertical position along the trajectory of the object.

The given parameters are:

$u = 7.5ms^{-1}$ --- the initial velocity
$v = 0ms^{-1}$ --- the final velocity
$a =-g$ --- the acceleration

To calculate the height (s) of the ball, we make use of the following equation of motion:

$v^2 = u^2 + 2as$

Substitute known values

$0^2 = 7.5^2 - 2gs$

$0 = 56.25 - 2gs$

Collect like terms

$2gs = 56.25$

Substitute 9.8 for g

$2 \times 9.8 s = 56.25$

$19.6 s = 56.25$

Divide both sides by 19.6

$s = 2.87$

Hence, the maximum height reached is 2.87 meters

What are the values the values of a and b?

Setler [38]

The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

$\frac{20}{a} = \frac{21}{20}$

Solving,

$21a =(20)(20) \\ 21a = 400 \\ a = \frac{400}{21}$

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

$\frac{b}{a} = \frac{21+a}{b}$

A little arithmetic shows that $21+a = \frac{841}{21}$ .

$\frac{b}{\frac{400}{21}} = \frac{\frac{841}{21}}{b} \\ b^2 = \frac{336400}{441} \\ b=\frac{580}{21}$
