Answer:
<em>f(10) or the power generated by the wind turbine at the wind speed of 10 m/s is </em><em>190.26 kW</em>
Step-by-step explanation:
The given polynomial function is,
where,
x represents the wind speed in meters per second,
y represents the kilowatts generated.
Putting x=10, we can get the value of f(10).
So,
Therefore,at x=10 or when the wind speed is 10 m/s, then y or the power generated by the wind turbine will be 190.26 kW
Answer:
x = 1/5
Step-by-step explanation:
Step 1: Write equation
-5x - (-7 - 4x) = -2(3x - 4)
Step 2: Solve for <em>x</em>
- <u>Distribute:</u> -5x + 7 + 4x = -6x + 8
- <u>Combine like terms:</u> -x + 7 = -6x + 8
- <u>Add 6x to both sides:</u> 5x + 7 = 8
- <u>Subtract 7 on both sides:</u> 5x = 1
- <u>Divide by 5 on both sides:</u> x = 1/5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)
-1 - (-7 - 4/5) = -2(3/5 - 4)
-1 - (-39/5) = -2(-17/5)
-1 + 39/5 = 34/5
34/5 = 34/5
Answer:
10 dimes and 14 quarters
Step-by-step explanation:
take the amount of four quarters to start with: 1$
then from here, for add one quarter and one dimes worth: 35 c
keep adding until you reach 450
then count how many 35 c you counted and thats how many dimes you have
add four to that number and youll get the amount of quarters
Answer:
84 days
Step-by-step explanation:
You would use the LCM to solve this.
12 and 7 don't share any common factors other than 1,
so you would multiply 12 x 7, which gets you 84.
After 84 days they would have raised the same amount.
El mínimo común múltiplo de 20 14 y 17 es <u>1</u>.
17 es un número primo, y su únicos múltiplos son 17 y 1.
