Answer:

2.11670 x 10^8

Step-by-step explanation:

211,670,000

To convert this standard notation number into a scientific number, you'll need to move the decimal 8 times to the left.

Remember, that the base of 10 always stays as 10. Only the exponent changes. We will be placing the 8 as the exponent since you moved the decimal 8 times to the left, making it 10^8 (if it were to the right, it would've been negative. I believe you'll learn more about that in class.) We can remove the zeros, thus leading to the answer of 2.11670 x 10^8.

If you have any questions, don't hesitate on asking! My math class just got on this topic! Hope this helped.

5/8 of the 64 musicians in a music contest are guitarists. Some of the guitarists play jazz solos, and the rest play classical s

motikmotik

The first thing we must do for this case is find the number of total guitarists.

We have then:

$(\frac{5}{8}) * (64) = 40$

We now look for the relationship between the number of guitarists playing jazz alone to the total number of guitarists.

We have then:

$\frac{x}{40} = \frac{1}{4}$

Where,

x: number of guitarists playing jazz alone

From here, we clear the value of x.

$x = (\frac{1}{4}) * (40)\\x = 10$

Then, the number of guitarists who play classical solo is:

$40 - 10 = 30$

Answer:

30 guitarists play classical solos in the contest

Find (fog)(x) when f(x)=x^2-7x+12 and g(x)=3/x^2-16

Kazeer [188]

Answer:

$f( \frac{3}{ {x}^{2} - 16 } ) = ({\frac{3}{ {x}^{2} - 16 }})^{2} - 7(\frac{3}{ {x}^{2} - 16 }) + 12 \\ = \frac{9}{ {x}^{4} - 32 {x}^{2} + 256 } - \frac{21}{ {x}^{2} - 16} + 12$

Find the value of x .. assume that segments that appear to be tangent are tangent .

Rus_ich [418]

Answer:

sqrt(277) =x

x is approximately 16.64331698

Step-by-step explanation:

This is a right triangle since 14 is tangent to the circle and 9 is a radius

We can use the Pythagorean theorem to solve this problem

a^2 +b^2 =c^2

9^2+14^2 =x^2

81+196 = x^2

277 = x^2

Taking the square root of each side

sqrt(277) = sqrt(x^2)

sqrt(277) =x
