Answer: c = 520
Step-by-step explanation:
f(2) = 578 means that when x = 2, the value is equal to 578. We will plug these knowns in and then solve for c.
Given:
f(x) = 4x³ + 7x² - x + c
Substitute:
578 = 4(2)³ + 7(2)² - (2) + c
Distribute:
578 = 4 * 2³ + 7 * 2² - 2 + c
Raise to the power of 3 and 2:
578 = 4 * 8 + 7 * 4 - 2 + c
Multiply:
578 = 32 + 28 - 2 + c
Add:
578 = 60 - 2 + c
Subtract:
578 = 58 + c
Subtract 58 from both sides:
520 = c
Reflexive property:
c = 520
Answer:
D. Kailey is not correct: 
is not written in scientific notation.
Step-by-step explanation:
We have been given that Kailey wrote 8,912,000 in scientific notation as . We are asked to choose the statement that best describes Kailey's work.
We know that to convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.
Upon looking at , we can see that 1st factor is 89.10, which is greater than 10. This means that Kailey did not write 8,912,000 in scientific notation.
Therefore, option D is correct choice.
Answer: 5 pounds
Step-by-step explanation: To convert 80 ounces into pounds, first find the conversion factor for ounces and pounds.
Conversion factor ⇒ 1 pound = 16 ounces
Next, notice that we're going from a smaller unit "ounces" to a larger unit "pounds." When we go from a smaller unit to a larger unit we divide.
So we divide 80 pounds by the conversion factor which is 16.
80 ÷ 16 = 5
This means that 5 pounds is equivalent to 80 ounces.
