Answer:

(1.5, - 2.5 )

Step-by-step explanation:

Using the midpoint formula

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ )

with (x₁, y₁ ) = (- 1, - 4) and (x₂, y₂ ) = (4, - 1) ← coordinates of endpoints

midpoint = [ 0.5(- 1 + 4), 0.5(- 4 - 1) ] = [ 0.5(3), 0.5(- 5) ] = (1.5, - 2.5 )

How do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Katyanochek1 [597]

Answer:

Step-by-step explanation:

exponents raised to a - power  is an inverse function probably not the right word

       a^-b    =  1/(a^b)     example       4^-2   = 1/(4^2)     =  1/16

so   (7^-1)^-1  is a double inverse which is back to the original number  7

      inverted 7 twice

      (7^-1)^-1     = (1/7)^-1     =  1/(1/7)     =   7     trust me or use your calculator

since the coeffients are the same  just add the powers...  some exponent rule

     5^2 * 5^4 * 5^-3   = 5^(2+4-3)   = 5³

here is it written out

5^2 * 5^4 * 5^-3    = 5²  ×   5^4   ×  5^-3    =   (5×5) × (5×5×5×5)  × (1/5×1/5×1/5)

    5×5 × 5× (5×5×5  × 1/5×1/5×1/5)           (5×5×5  × 1/5×1/5×1/5)  = 1

    5×5×5    = 5³

   so

Here are two patterns made using identical rhombuses. Write one equation to show how to find the value of ​a​ and one equation t
algol13

Answer:

Equation 1​

6*a = 360°

Equation 2

2*a + 2*b = 360°

a = 60°

b = 120°

Step-by-step explanation:

From the first picture we can see that 6 angles a° made a complete circle, that is, 360°. So:

6*a = 360°

a = 360°/6 = 60°

From the second picture we can see that 2 angles a° and 2 angles b° made a complete circle, then:

2*a + 2*b = 360°

2*b = 360° - 2*60°

b = 240°/2 = 120°

54,984 rounded to the nearest ten thousand would be 50,000 since you are rounding to the nearest 10,000 you will round 4,000 to 50,000
