Answer:
B. 440 feet per second
Step-by-step explanation:
What you need to do is first convert miles to feet and then hours to seconds. Then you should be able to get the answer
Answer:
The answer is option B: No it is too high
Step-by-step explanation:
Calculating the total numbers of heart made, we have
21 + 29 + 12 = 62 hats
If Edna wants to split 62 hats evenly between two hospital, then each hospital will get
62/2 = 31 hats
Therefore, if Edna works out that each hospital gets 62 hats, No it is too high, as that is the total of all the hat that is available
Solve:
3x^2 - 5x + 7 = 0
Answer : x = 5/6 + i sqrt 59/6, x = 5/6 + i sqrt 59/6
Solve the Equation:
3x^2 - 5x + 7 = 0
Step 1: Use quadratic Formula with a = 3, b = -5, c = 7:
x = -b +/- sqrt b^2 - 4ac/ 2a
x = - ( - 5) +/- sqrt ( - 5)^2 - 4(3)(7)/ 2(3)
x = 5 +/- sqrt - 59/6, which will become, x = 5 +/- sqrt i 59/6, x = 5 +/- sqrt i 59/6
No Real Solutions:
Your answer would be, Letter Choice, (D), x equals the quantity of plus, or minus i sqrt 59 all over 6. Hence, No Real Solutions
Hope that helps!!!! : )
Answer:
1. x = ±9
2. 
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
We have,
Question 1. 
i.e. 
i.e. x = ±9.
Question 2. 
i.e. 
i.e. 
i.e.
Question 3. [tex]f(x)=x^{2}-144[tex]
For the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
So, the options are 12 and -12.
Question 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
So, Antoine is incorrect. There exists two solutions x=5 and x= -5.
i’m unsure on how to do this, i’m sorry
