Step-by-step explanation:

Use the Pythagorean Theorem to find the missing sides in the triangles.

c^{2} = a^{2} + b^{2}

Q2. c^{2} = 8^2 + 40^2

c^{2} = 1664

c = \sqrt{1664}

c = 8\sqrt{26}

Find the missing sides of the other triangles and figure out which ones are the same.

Q3. Do the same thing as Q2.

What is the common ratio between successive terms in the sequence? 2, -4, 8, -16, ​
Marianna [84]

Answer:

the answer is f(x) = n*(-2)

ratio is the wrong word to use, it is for contolled variation in probability. a sequence is controlled by what is known as a function - f(x) is the symbol for a function

Step-by-step explanation:

the following number of the previous one in the sequence is derived by the function f(x)=n*(-2)

2 x -2 = -4 (positive x negative = negative)

-4 × -2 = 8 (negative x negative = positive)

8 x -2 = -16 (positive x negative = negative)

so in the sequence, the trend of -,+ double will go on

What is 3 1/2 - 2 5/7 and show the work
Hunter-Best [27]
3 \frac{1}{2}  -2 \frac{5}{7} = \frac{(3\cdot2)+1}{2} -  \frac{(2\cdot7)+5}{7} =  \frac{7}{2} -  \frac{19}{7} \\\\= \frac{7\times 7}{2\times 7} -  \frac{19\times 2}{7\times 2} =  \frac{49}{14} - \frac{38}{14} \\\\= \frac{49-38}{14} =\boxed{\bf{\frac{11}{14}}}
