Kaya devoted 2/5 of her study time to mathematics, 3/20 of her time to social studies, 1/3 of her time to chemistry and the rema
andrezito [222]

Answer:

  54 minutes

Step-by-step explanation:

The sum of fractions is ...

  2/5 + 3/20 + 1/3 = 11/20 +1/3 = (3·11 + 20·1)/(20·3) = 53/60

Then the 42 minutes devoted to English represents 1 - 53/60 = 7/60 of her study time.

Kaya's social studies time is 3/20 = 9/60 of her total, so the ratio of SS to Eng is ...

  SS : Eng = (9/60) : (7/60) = 9 : 7

When we multiply the numbers in this ratio by 6, we find ...

  SS : Eng = 54 : 42

Kaya spent 54 minutes studying social studies.

Determine the end behavior of the polynomial function. f(x)=-3x^4-2x^3+2x^2+ 3x +5 a) falls to the left and rises to the right b
Molodets [167]

Answer:

Option b is correct

Step-by-step explanation:

In order to check the end behavior of a  polynomial function we   just check the leading term and its coefficient and the procedure is as  follows:

Here we can see that highest exponent of the polynomial function is 4

therefore degree of the polynomial is 4. and therefore  -3x^4 is leading term.  

because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of  leading is negative therefore it falls at both ends. that is  falls to  the left and falls to the right.

therefore option b is correct.
