Step-by-step explanation:
<h3>Part A</h3>
<u>Multiply the energy produced in 1 second by the number of seconds:</u>
- erg
<h3>Part B</h3>
10⁻³ is same as 0.001 times and 10³ is same as 1000 times.
1.6*1000 = 1600 mm = 160 cm = 1.6 m is way too big for the measurement of the distance between the tracks on a CD.
So the first option is correct.
Slope is rise over run.
40. the rise is $0.90 and the run is 6 years, so the annual rate of change is .9/6 = $0.15 per year
40) Final answer: $0.15 per year
For 41-48, find the difference between the given values of the same variable, then multiply by the slope and add/subtract from the variable whose second value is missing (sorry if that's confusing)
41. 9-6=3 => 3*(-1)=-3 => 2+3=-1
41) Final answer: r=-1
42. 4-3=1 => 1*8=8 => (-5)-8=-13
42) Final answer: r=-13
43. 5-2=3 => 3*(4/3)=4 => -3+4=1
43) Final answer: r=1
44. 7-3=4 => 4*(3/4)=3 (flip the slop to find x values) => -2-3=-5
44) Final answer: r=-5
45. (-1/4)-(-5/4)=4/4=1 => 1*(1/4)=1/4 (again flip the slope) => 1/2-1/4=1/4
45) Final answer: r=1/4
46. 1-(2/3)=1/3 => (1/3)*(1/2)=(1/6) (don't have to flip this time) => (1/2)-(1/6)=1/3
46) Final answer: r=1/3
For 47 and 48, I'll setup an equation for r
47. (4-r)*(-5/3)=r-2 => -20/3+(5r)/3=r-2 => -14/3+(5r)/3=r => -14/3=-(2r)/3 => -14=-2r => r=7
47) Final answer: r=7
48. (R-(-2))*(-2/9)=5-r => -2(r+2)/9=5-r => -(2r)/9-4/9=5-r => -(2r)/9=49/9-r => (7r)/9=49/9 => 7r=49 => r=7
48) Final answer: r=7
Hope I helped :)
Answer:
The function form of the given equation
y = 2 x + 3
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given 4x - 2y = -6
4 x + 6 = 2 y
y = 2 x + 3
The function form y = f(x)
The function form of the given equation
y = 2 x + 3
Answer:
Percentages would be a change from $55 to $85 a week this is found by dividing. = 55 / 85 = 64.705882352941%
64.7%
We could also consider ratio if two people or two products cost had two amounts per week ie) car insurance vs home insurance
55 to 85 = 55:85 = 11:17
We have found prime number ratio and they are simplified numbers of 55:85
Step-by-step explanation:
First you need to combine like terms
13x+8-15x=6+x+11
-2x+8=x+17
-x -8 -x -8
-3x=9
--- ----
-3 -3
x=-3
I hope I've helped!
