In order to answer the question, we simply substitute the value of p and q to the given expression and solve. We do as follows:

P^2q^2+pq–q^3–p^3
0.5^2(-0.5)^2+0.5(-0.5)–(-0.5)^3–(0.5)^3
-3/16 or -0.1875

Hope this answers the question. Have a nice day.

Kalsom answers 25 questions in math tests. He scored 81% to 93%. Calculate all possible number of questions successfully answere

cricket20 [7]

Answer:

21 and 22

Step-by-step explanation:

Let's work backward from that 81%: x/25 = 0.81 yields x = 20.25. Nominally, 20.25 / 25 = 0.81, but x must be an integer. Let's round 20.25 off to 20.

Thus, if Kalsom got 81%, it was a result of his having done 20 questions correctly.

81% corresponds to 20 questions correct;

82% to 20.5 questions correct, or, rounding up, to 21 questions correct;

83% to 20.75, or 21;

84% to 21 questions correct; this is the only result that makes sense (whole number of questions answered correctly)

85% to 21.25;

86% to 21.5;

87% to 21.75;

88% to 22 questions correct (this makes sense, unlike the last three)

89% to 22.25;

90% to 22.5;

91% to 22.75;

Assuming that the number of questions correct MUST be integer, then the possible number correct are 21 and 22, corresponding to 84% and 88% respectively.

Answer pwease lol now

Anettt [7]

Answer:

D) y = 27 · (3)^x

Step-by-step explanation:

Replace x with the x values.

27 · (3)^-2 = 27 · 1/9 = 3

27 · (3)^-1 = 27 · 1/3 = 9

27 · (3)^0 = 27 · 1 = 27

27 · (3)^1 = 27 · 3 = 81

17 · (3)^2 = 27 · 9 = 243

D is your answer.

Hope this helps

A square has a diagonal of 44in. I want to frame the picture, how many inches of frame do I need

dimaraw [331]

The square has a 44-inch diagonal.

The pythagorean equation must be used to obtain the hand.

Diagonal (d) ^ 2 = side^2 + side ^ 2

Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2

44^2 = 2s^2

1936 = 2s^2

2s^2 = 1936

s^2 = 968

s = 31.11 inches

The length of the side is around 31 inches

Perimeter = 4*s

Perimeter = 4 * 31

Perimeter = 124 inches

As a result, you will need a total of 124 inches to frame the rectangle.

Hope this helps you!!

Helen [10]

Answer:

y= 1/12(x-0)^2+0

this answer works as an upward parabola

Step-by-step explanation:

The formula for a veritcal parabola is y=1/4p(x-h)^2+k
(h,k)= coordinates of the vertex of the parabola
p= absolute value of the distance from the vertex to the focus/directrix
In this problem, it is given that the vertex is at the origin (0,0) and the focus (the bulb), is 3 centimeters away from the vertex.
Now, you know the values of the variables. Fill in the values
FROM THE FORMULA: 1/4p turns into 1/12 since p is 3.
(x-h)^2+k turns into (x-0)^2+0, since h and k where the values of the vertex which was 0,0
once all the variables are given values (except x and y) you have made your equation!
The answer is y=1/12(x-0)^2+0

MARK BRAINLIEST! this took forever, and I know this is the right answer since I got a perfect grade when I turned mine in.
