Because relationship B has a greater rate, the heat should be increasing more.
Thus the answer is B because in the original, the rate from 2 to 3 was 64.9-61.3=3.6 while in table B, the change is 64.3-60.6=3.7 and 3.7>3.6

Answer:

(B) Time (min) 2 , 3 , 7 , 9

Temperature (°C) 60.6 , 64.3 , 79.1 , 86.5

Step-by-step explanation:

The rate of change is found by using the formula for slope:

m=\frac{y_2-y_1}{x_2-x_1}

For option A, this gives us

m =(64.4-61.0)/(3-2) = 3.4/1 = 3.4

This is not more than relationship A.

For option B, we have

(64.3-60.6)/(3-2) = 3.7/1 = 3.7

This is more than relationship A.

For option C, we have

(65.3-61.8)/(3-2) = 3.5/1 = 3.5

This is not more than relationship A.

For option D, we have

(64.6-61.0)/(3-2) = 3.6/1 = 3.6

This is not more than relationship A.

Rewrite the quadratic function in intercept or factored form<br> y=-40x+2x^2-2x
poizon [28]

Answer:

y = 2x(x - 21)

Step-by-step explanation:

The given quadratic function y = -40x + 2x^2 - 2x

This can be rearranged as

y = 2x^2 - 2x - 40x

Here the Greatest Common Factor is 2x, we can take it out and write the remaining term in parenthesis.

y = 2x(x - 1 -20)

y = 2x(x - 21)

That's the answer.

Hope this will helpful.

Thank you.

Find the smallest value of k such that the LCM of<br> k and 6 is 60
Advocard [28]

Answer: The smallest valuest value for<em> k </em>is 10, such that LCM o<em>f k</em> and 6 is 60.

Step-by-step explanation:

We know that, LCM = Least common multiple.

For example : LACM of 12 and 60  is 60.

If LCM of k and 6 is 60.

i.e. the least common multiple of k and 6 is 60.

Since, 10 x 6 = 60.

The smallest valuest value for<em> k </em>should be 10, such that LCM o<em>f k</em> and 6 is 60.

Hence, the smallest value of k is 10.
