Which graph represents an odd function?<br><br>Answer by using: A, B, C, or D for each graph.
AnnZ [9099]

Answer: Option C is the correct graph.

Explanation:

An odd function satisfies the condition,

f(-x)=-f(x)

This indicates that for any point (x,y) on the graph, the point (-x,-y) will also be present.

Why Option C is correct:

Option C includes the point (1,2), which implies the point (-1,-2) must be present.

f(1)=2

Indeed, (-1,-2) is among the points.

f(-1)=-f(1)=-2

Other pairs like (2,3) with (-2,-3), (3,-1) with (-3,1), and (4,0) with (-4,0) are also found. Hence, the function represented is odd.

Why other options are incorrect:

In Option A, (1,3) is given, so at x = -1, y should be -3, but instead y = 1, so it’s not odd.

Option B has (1,0), so at x = -1, y should be 0, but y = -3, so it is not odd.

Option D features (1,-1), meaning at x = -1 y should be 1; however, y = -1, so it's not odd.

Maximum value of x3y3 + 3 x*y when x+y = 8.
Inessa [9000]

Response:

The outcome is 4144.

Detailed explanation:

We need to determine the peak value of f(x)= x^{3}y^{3}+3xy when x+y=8

We can represent x+y=8 as y=8-x

Plugging the value of y

f(x)=x^{3}(8-x)^{3} +3x(8-x)

= 3x^{2}(8-x)^{2}[-x+8-x]+3[-x+8-x]

= 3(8-2x)[x^{2}(8-x)^{2}+1]

To find the maximum, we'll set the equation to 0.

Thus, we find:

8-2x=0 => x = 4

And since y=8-x

y =8-4= 4 > y = 4

Hence, we will substitute these values into the equation to ascertain the maximum value.

= x^{3}y^{3}+3xy

= xy(x^{2}y^{2}+3)

= 4\times4((16\times16) +3)

= 16(259) = 4144

Answer:

The upper bound of the confidence interval is 3127 $/day.

Step-by-step explanation:

With the new sample, we can determine the one-sided 95% confidence interval.

For this interval (one sided, with 95% confidence), z=1.64.

The total number of observations (n) is 45 days.

The average is 2984 and the standard deviation is 585.

We can estimate the upper limit of the confidence interval as

UL=X+z*s/\sqrt{n} \\UL = 2984 + 1.64*585/\sqrt{45}=2984+ 959.4/6.708=2984+143=3127

243.875 to nearest tenth, hundredth, ten, and hundred
Inessa [9000]
When rounding 243.875: to the nearest tenth, it becomes 243.9; to the nearest hundredth, it is 243.88; to the nearest ten, it rounds down to 240; and to the nearest hundred, it rounds down to 200. The general rule in rounding states that if the decimal is less than 5, the number remains the same; if it is 5 or more, you round up.

Four hot air balloons each descend 295 feet per minute for 7 minutes. Find the total change in altitude for all 4 balloon
Svet_ta [9500]

Answer: A total descent of 8260 feet occurred for all four balloons.

Step-by-step explanation:

Based on the information provided:

Number of hot air balloons = 4

Minutes of descent = 7

Descent rate per minute = 295 feet

Thus, the overall change in altitude for all four balloons can be calculated as:

295\times 7\times 4\\\\=8260\ feet

Thus, a total descent of 8260 feet was experienced by the four balloons.
