Answer : The perfect squares are, 36, 16, 81 and 64

Step-by-step explanation :

Perfect square : It is a number made by squaring a whole number.

For example:

2 × 2 = 2² = 4

So, 4 is a perfect square.

3 × 3 = 3² = 9

So, 9 is a perfect square.

4 × 4 = 4² = 16

So, 16 is a perfect square.

5 × 5 = 5² = 25

So, 25 is a perfect square.

6 × 6 = 6² = 36

So, 36 is a perfect square.

7 × 7 = 7² = 49

So, 49 is a perfect square.

8 × 8 = 8² = 64

So, 64 is a perfect square.

9 × 9 = 9² = 81

So, 81 is a perfect square.

and so on ............

Hence, from the given numbers we conclude that 36, 16, 81 and 64 are perfect squares.

Which represents the solution of the graphed system of equations, y=x^2-2x and y=-2x-1
elena55 [62]

Answer:

x = √(-1) = i

Since the value of √(-1) is not real.

The system has no real solution.

Step-by-step explanation:

The solution to the system of equations is at the point where they intercept each other.

y1 = y2

For the given equation;

y=x^2-2x and y=-2x-1

To get the where they intercept, we will equal both equations;

y=x^2-2x = -2x-1

x^2 - 2x = -2x - 1

x^2 - 2x + 2x + 1 =0

x^2 +1 = 0

x^2 = -1

x = √(-1) = i

Since the value of √(-1) is not real.

The system has no real solution.

sweet [91]

Answer:

36.67 [mile/hour].

Step-by-step explanation:

1) use the formula: V=S/t, where S - entire jorney, v - average speed (required to calculate), t - elapsed entire time.

2) according to the formula above S=50+60=110 miles; t= 50/40 + 1.75=1.25+1.75=3 hours.

3) after the substitutuion  110 and 3 into the formula above:

v=110/3≈36.67 miles/h.

Jonathan wants to buy a lid for his frying pan. The diameter of the pan is 10 inches. What is the approximate circumference Of a
mihalych1998 [28]

Answer: 31.42 inches.

Step-by-step explanation:

Since the circumference of a circle equation is C = πd (also C = 2πr, in which 2*r = d), you can just substitute d = 10.

Then you get C = π*10 ≈ 31.42 inches.
