The number of students in Mrs. Patrick's piano class decreased by 15% in 2 years to 17 students. How many students did she have

guapka [62]

Answer:

20 students

Step-by-step explanation:

If the class decreased by 15%, the students that she has now (17) represents a percentaje of:

100% - 15% = 85%

so the 17 students are 85% of what she had:

Students Percentage

17 ⇒ 85%

and we are looking for how many students she had 2 years ago, thus we are looking for the 100% of students (the original number of studens). If we represent this number by x:

Students Percentage

17 ⇒ 85%

x ⇒ 100%

and we solve this problem using the rule of three: multiply the cross quantities on the table( 17 and 100) and then divide by the remaining amount (85):

x = 17*100/85

x = 1700/85

x=20

2 years ago she had 20 students

Rewrite the function by completing the square h(x)=4x^2+4x+1

lisov135 [29]

Answer:

$h(x) = 4(x+\frac{1}{2})^{2}$

Step-by-step explanation:

$h(x)=4x^2+4x+1\\h(x)=4(x^2+x+\frac{1}{4}) \\h(x)=4(x^2+x+\frac{1}{4})\\h(x) = 4(x+\frac{1}{2})^{2}$

Can anyone help me!?!?!?!?! Here is my question:

Maslowich

The sine function has a minimum value of -1, so f(x) = 4sin( ) -1 will have a minimum value of -5.

g(x) obviously has a minimum value of -3.

h(x) has a squared term that cannot be negative, so its minimum value is +4.

f(x) has the smallest minimum value.
