A function F(x) is such that F(-x) = F(x). If F(2) = -5. which of the following points must also be on the graph of F(x)? A. (-2,5) B. (2.5) C. (-2,-5) D. (-5. 2) E. (-5, -2)
Answer:
(-2,-5)
Step-by-step explanation:
Since F(x)=F(-x), F(2)=F(-2)=-5
So, (-2,-5) must be on F(x)
The volume of a circular cylinder is calculated using the formula
Answer:
6%
Step-by-step explanation:
Since the volume of the cylinder V = πr²h where r = radius of cylinder and h = height of cylinder and h = 2r, we have that r = h/2.
Substituting r into v, we have
V = πr²h
V = π(h/2)²h
V = πh³/4
Now let ΔV be the error in the volume and Δh be the error in the height.
Since h is raised to the power of 3,
ΔV/V = 3Δh/h
multiplying both sides by 100, we have
ΔV/V × 100 = 3Δh/h × 100
So, we have
ΔV/V × 100 = 3 × Δh/h × 100
since Δh/h × 100 = percentage error in height = 2%, and ΔV/V × 100 = percentage error in volume,
ΔV/V × 100 = 3 × 2% = 6%
So, the percentage error in volume is 6 %

Let event A = The student plays basketball.
Let event B = The student plays soccer.
What is PlA or B)?
The probability P(A or B) is equal to 5/10 = 0.5
How to find the probability?
P(A or B) is the probability that a randomly selected student plays either basketball of soccer.
On the diagram, we can see that there are a total of 10 students, such that 2 play only basketball and 3 play only soccer.
P(A or B) is equal to the quotient between the number of students that play one of the sports (here we don't count the ones that play both sports) and the total number of students.
Then we have:
P(A or B) = (2 + 3)/10 = 0.5

Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets. Manny would like a mixture of 60% detergent and 40% water in 5-gallon buckets. To make this, he combines some 80/20 mixture with some pure water in each 5-gallon bucket. How many gallons of pure water does Manny add to each 5-gallon bucket? Express your answer as a decimal to the nearest hundredth.
Answer:
1.25 gallons of pure water
Step-by-step explanation:
Manny's cleaning supply store receives a mixture of 80% detergent and 20% water in 15-gallon buckets.
0.80 d + 0.20w = 15 gallon
Manny would like a mixture of 60% detergent and 40% water in 5-gallon buckets.
0.60d + 0.40w = 5 gallon
0.80 d + 0.20w = 15 ....... Equation 1
0.60d + 0.40w = 5 ......….. Equation 2
Using elimination method
Multiply Equation 1 with 0.60
Multiply Equation 2 with 0.80
We eliminate d
0.80 d + 0.20w = 15 × 0.6
0.60d + 0.40w = 5 × 0.8
=
0.48d + 1.2w = 9....... Equation 4
0.48d + 3.2w = 4..... Equation 5
Subtract Equation 5 from 4
= - 2.0w = -5
w = -5/-2
w = 2.5 gallons.
Hence: 2.5 gallons/2
= 1.25 gallons.
Therefore, Manny adds 1.25 gallons of pure water.

which table has a constant of proportionality between Y and X of 1/5?
Answer:
B
Step-by-step explanation:
From the table B has a constant of proportionality between y and x of 1/5.
We need to find which table has a constant of proportionality between y and x of 1/5.
What is constant of proportionality?Constant of proportionality is the constant value of the ratio between two proportional quantities.
The equation for direct proportionality is y = kx, which shows as x increases, y also increases at the same rate.
Now, k=y/x
From table A:
k=4/5 ÷ 2
=2/5
k=14/5 ÷ 7
=2/5
k=24/5 ÷ 12
=2/5
From table B:
k=8/5 ÷ 8
=1/5
k=9/5 ÷ 9
=1/5
k=2/10 =1/5
From table C:
k=16/5 ÷ 3
=16/15
k=26/5 ÷ 5
=26/25
k=36/5 ÷ 7
=36/35
Therefore, from the table B has a constant of proportionality between y and x of 1/5.

Find three consecutive odd integers such that the sum of the first and the third is 70. Find the integers.
Answer:
33, 35, 37
Step-by-step explanation:
Let the tree consecutive odd integers be x, x +2 and x + 4
According to the given information:
Sum of the first and the third is 70
[tex] \therefore x + x + 4 = 70\\\\
\therefore 2x = 70 - 4\\\\
\therefore 2x = 66\\\\
\therefore x = \frac{66}{2}\\\\
\therefore x = 33\\\\
\implies x + 2 = 33 + 2 = 35\\\\
\& \hspace{25 pt}x + 4 = 33 + 4 = 37\\\\[/tex]
Thus, the three consecutive odd integers are 33, 35 and 37.
