Answer:

594 rpm

Step-by-step explanation:

Two gears will have the same linear speed, so:

v₁ = v₂

ω₁ r₁ = ω₂ r₂

(316 rpm) (79) = ω (42)

ω ≈ 594 rpm

Decide whether each number is written in standard notation or scientific notation.
VARVARA [1.3K]

The answers are as follows:

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7  - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

Concept: Standard notation is a way of writing a number so it is easier to read. It is often used for very large or very small numbers.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

In the given questions,

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7  - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

For the function f(x) = -x^3 + 2x^2 + x - 2
kaheart [24]

Answer:

Step-by-step explanation:

a)

f(1)=-1^3+2*1^2+1-2=-1+2+1-2=0\\\\

b)

Rationnel roots are divisor of -2: -1,1,-2,2

f(-1)=-(-1)^3+2*(-1)^2+(-1)-2=1+2-1-2=0\\\\\begin{array}{c|cccc}&x^3&x^2&x&1\\---&---&---&---&---\\&-1&2&1&-2\\x=1&&-1&1&2\\&-1&1&2&0\\\\x=-1&&1&-2\\&-1&2&0\\---&---&---&---&---\\\end {array}\\\\\\f(x)=-x^3+2x^2+x-2=(x-1)(x+1)(-x+2)\\\\

Simplify 9 to the 2nd over 9 to the 7th.
Gekata [30.6K]
Use the exponent rules 
x^a/x^b =1/x^b-a

 9^2/9^7 = 1 / 9^7-2 = 1/9^5
1 over 9 to the 5th = 59049 
so it would be 1/59049
