Answer: 1/2500 n
Step-by-step explanation:
Write the quadratic equation whose roots are - 5 and -4, and whose leading coefficient is 3.
Answer:
The quadratic equation is
3x^2+ 27x + 60
Step-by-step explanation:
Here, we have the roots -5 and -4 and the leading coefficient of 3
Mathematically, we simply have this done to the roots;
x = -5 implies x+ 5
x = -4 implies x + 4
The product of this two will be;
(x + 5)(x + 4)
= x^2 + 5x + 4x + 20
= x^2 + 9x + 20
we add the leading coefficient
that would be;
3(x^2 + 9x + 20)
= 3x^2 + 27x + 60

Step-by-step explanation:
Karen bought a $6.95 canvas and 8 tubes of paint. She spent $24.95 on the canvas and the paints. Which equation can be used to find the cost of each tube of paint?
A. 6.95 + 8c = 24.95
B. 8 - 6.95c = 24.95
C. 6.95 - 8c = 24.95
D. 8 + 6.95c = 24.95
Answer:
A
Step-by-step explanation:
Answer:
A. 6.95 + 8c = 24.95
Step-by-step explanation:
Well, the answer to this question is A is because if we carefully look at this problem, then we can see that Karen bought a canvas for $6.95 and she also bought 8 tubes of paint. Now, the total amount of money that she spent is $24.95.
So, in this problem, our $6.95 is the cost for the canvas that she bought whereas when she mentions buying 8 tubes of paint, she doesn't mention how much each tube of paint costs so, the cost for one tube of paint is unknown and thus, it is a variable.
So, in conclusion, the answer to this question is definitly, A. 6.95 + 8c = 24.95

★ m=2 is the right answer.!!!Quick!!! Barbara can walk 3200 meters in 24 minutes. How far can she walk in 3 minutes? (In Meters)
Answer:
400 meters
Step-by-step explanation:
First, divide 3,200 by 24 to find the rate, which is 133.3 (repeated).
Now, multiply 133.3 by 3, which is your answer! 133.3*3=399.9. 399.9 is extremely close to 400, so we can just round it to that.
Hope this helps you out and have a wonderful day (✿◡w◡)

Second term of the sequence = 9
Put n=3
a₃ = 5(3)-1 =15-1 =14
Third term of the sequence = 14
Put n=4
a₄ = 5(4)-1 = 20 -1 = 19
Fourth term of the sequence = 19
Put n=5
a₅ = 5(5)-1 = 25-1 =24
Fifth term of the sequence = 24
Final answer:-
The first five terms of the sequence
4 , 9 , 14 , 19 , 24 this is an arithmetic progression

A study found that the average time a person spent exercising each week was 84 minutes, but there could be up to a 3% error in this
number. Which of these could be the actual average time spent?
es
A)
78.32 minutes
B)
81.48 minutes
C)
87.32 minutes
D)
88.64 minutes
B is the answer
Answer:
C
Step-by-step explanation:
The actual average time = 81.5 minutes
The correct answer is an option (B) 81.48 minutes
What is percent error?"percent error = [(estimated value - actual value) / (actual value)] × 100"
For given example,
percent error (e) = 3%
estimated average time spent (x) = 84 minutes
We need to find the actual average time spent (y)
Using the formula of percent error,
⇒ e = [(x - y)/y] × 100
⇒ 3 = (84 - y)/y × 100
⇒ (84 - y)/y = 3/100
⇒ (84 - y) / y = 0.03
⇒ 84 - y = 0.03y
⇒ 84 = 0.03y + y
⇒ 84 = (1.03)y
⇒ y = 81.5 minutes
Therefore, the actual average time = 81.5 minutes
The correct answer is an option (B) 81.48 minutes

Step-by-step explanation:
The solution of the equation:
x = -0.28 to the nearest tenth.
x = 4.53 to the nearest tenth.
What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
A quadratic equation,
4x²-27x-5 = -10x
Simplifying,
4x²-27x-5 + 10x = 0
4x²-17x-5 = 0
So,
x = {-(-17) ± √(289 + 80)}/8
x = (17 ± √369) / 8
When we take - sign,
x = - 0.276
x = -0.28 to the nearest tenth.
When we take + sign,
x = 4.526
x = 4.53 to the nearest tenth.
Therefore, the values are x = -0.28 and x = 4.53.
