In this case, the best way to work this out is to find what 1cm is equal to. In this case, you have to divide 51/3, giving you 17. You know that 17 feet. You can now divide 187/17, giving you 11. Therefore, 11cm is equal to 187 feet. Hope this helps

How to solve (3p⁴ + 2q⁴)²​
IRINA_888 [86]

Answer:

9p⁸ + 12p⁴q⁴ + 4q⁸

Step-by-step explanation:

(3p⁴ + 2q⁴)²​ ⇒ The square of (3p⁴ + 2q⁴)

Squares are such bases that multiply itself two times.

⇒ (3p⁴ + 2q⁴)(3p⁴ + 2q⁴)

<u>Simplifying the expression using (a + b)(a + b) = (a x a) + (ab) + (ab) + (b²)</u>

⇒ (9p⁸ + 6p⁴q⁴ + 6p⁴q⁴ + 4q⁸)

⇒ (9p⁸ + 12p⁴q⁴ + 4q⁸) = 9p⁸ + 12p⁴q⁴ + 4q⁸

The sum of the digits of a two-digit number is 12. The number formed by interchanging the digits is 54 more than the original nu
MArishka [77]
Let's call the digits of the number ab a and b. Then the information in the question can be expressed as

a+b=12 => b=12-a
a*10+b + 54 = b*10+a => 9a + 54 = 9b

9a + 54 = 9(12-a) => 18a = 54 => a=3

b=12-a; b=9

39 swapped gives 93, 39+54=93

Find an equation of the circle whose diameter has endpoints (2,3) and (-4,5)
natka813 [3]

Answer:

(x+1)² + (y-4)² = 10

Step-by-step explanation:

The diameter of a circle has the endpoints at (2,3) and (-4,5).

Therefore, the length of the diameter is given by

\sqrt{(2-(-4))^{2}+(3-5)^{2}} = 2\sqrt{10}

Hence, the radius of the circle is √10.

Now the midpoint of the line joining (2,3) and (-4,5) will be the center of the straight line.

Hence, the center will be at (\frac{2-4}{2},\frac{3+5}{2}) =(-1, 4)

Therefore the equation of the circle is  

(x+1)² + (y-4)² = (√10)²

⇒  (x+1)² + (y-4)² = 10 (Answer)
