Answer:
3) D
4) D
5) B
6) B
Step-by-step explanation:
3) A "Pythagorean triple" is a set of 3 integers that could be the sides of a right triangle. The only triangle shown with integer side lengths is choice D.
__
5) The only triangle for which the square of the hypotenuse is the sum of the squares of the other two sides is choice D.
11² +2² = (5√5)²
121 + 4 = 125
__
6) The lengths of sides of each right triangle are 2/3 of those of choice D in problem 4. That is, they are a 7-24-25 triangle, multiplied by 2. That means the height is 24·2 = 48, and the area is ...
A = 1/2bh
A = 1/2(28 m)(48 m) = 672 m² . . . . matches choice B
__
7) The side lengths of a 30-60-90 triangle have the ratios 1 : √3 : 2. That is, the short leg is half the hypotenuse, a fact stated in A and D. Those true statements make it clear that statement B is false.

Answer:
-2.75
-1.75
-0.75
0.25
1.25
Step-by-step explanation:
<em>The</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>given</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>top</em><em> </em><em>row</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>table</em><em>.</em><em> </em><em>We</em><em> </em><em>can</em><em> </em><em>complete</em><em> </em><em>the</em><em> </em><em>rest</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>table</em><em> </em><em>by</em><em> </em><em>plugging</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>corresponding</em><em> </em><em>values</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>into</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>and</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>y</em><em>.</em>
<em>F</em><em>or</em><em> </em><em>example</em><em>:</em>
y = (-2) - 3/4 = -2.75
y = (-1) - 3/4 = -1.75
y = (0) - 3/4 = -0.75
y = (1) - 3/4 = 0.25
y = (2) - 3/4 = 1.25
The answer is B, 2.5x
2.5 is the average of how many times higher they can jump and x is the average person
