Answer:
(4, - 0.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 
, 
]
Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then
midpoint = ( 
, 
) = 
, 
) = (4, - 0.5 )
Answer:
<h2>64x³ - 432x² + 972x - 729</h2>
Step-by-step explanation:
Write the statement into an expression
<h2>(4x - 9)³</h2><h2 /><h3>Now multiply that out...</h3><h3 /><h3>(4x - 9)²(4x - 9)</h3><h3 /><h3> Foil the first binomial</h3><h3 /><h3> (16x² - 72x + 81)(4x - 9)</h3><h3 /><h3>Multiply the two polynomials together</h3><h3 /><h3> 16x²(4x) - 72x(4x) + 81(4x) + 16x²(-9) - 72x(-9) + 81(-9)</h3><h3 /><h3> 64x³ - 288x² + 324x - 144x² + 648x - 729</h3><h3 /><h3>combine like terms...</h3><h3 /><h3>64x³ - 432x² + 972x - 729</h3>
Hi,
if growth continue to the same rate, meaning +25% more every year, then B is the answer :
100 (1.25)^t
7. 55 + 35 + x = 180 x = 90 making the triangle a right triangle.
