Answer:

<h2>b) 50in, 48in, 14in</h2>

Step-by-step explanation:

If <em>a ≤ b < c</em><em> </em>form of a right side, then <em>a² + b² = c²</em>

a) 3ft, 6ft, 5ft

3² + 5² = 6²

9 + 25 = 36

34 = 36        <em>FALSE</em>

b) 50in, 48in, 14in

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500     <em>CORRECT :)</em>

c) 53m, 48m, 24m

24² + 48² = 53²

576 + 2304 = 2809

2880 = 2809     <em>FALSE</em>

d) 8cm, 17cm, 14cm

8² + 14² = 17²

64 + 196 = 289

260 = 289    <em>FALSE</em>

Every year the population of students in a certain school district is recorded. In 2014, MVCSD had a population of 7,895 student
Fudgin [204]

Answer:

\boxed{2211}

Data:

Population in 2014 = 7895

            % increase = 28 %

Calculations:

              28 %  =  (Increase/Original number) × 100 %

                  28  =  (Increase/7895) × 100

28/100 × 7895 = Increase     Multiplied each side by 7895/100

         Increase = 2211

\boxed{ 2211} students were recorded in the MVCSD in 2018.

Point G is the centroid of the right △ABC with hypotenuse AB=18 in. Find CG.
Rama09 [41]
<h3>Answer:</h3>

6 in

<h3>Explanation:</h3>

Let M be the midpoint of AB. ∆CMB and ∆CMA are both isosceles triangles, so CM = (AB)/2 = 9 in.

CG = (2/3)(CM) = (2/3)(9 in)

CG = 6 in

_____

<em>Comment on centroid and median</em>

The centroid of a triangle is located 1/3 the distance from the midpoint of a side to the opposite vertex. This is true for any median in any triangle. The proof can be developed from the fact that every median divides the triangle's area in half. Here, we just take advantage of this fact.

Suppose that the function g is defined, for all real numbers, as follows g(x)=[-1/4x+1 If x&lt;-2} -(x+1)^ 2+1 If -2 ≤ x ≤ 2 2 I
Sergeeva-Olga [200]

Answer:

(a)0

(b)1

(c)2

Step-by-step explanation:

The function g is defined as follows:

g=\left\{\begin{array}{ccc}-\frac{1}{4}x+1, &x2\end{array}\right\\

(a)g(x)=-(x+1)^2+1, -2\leq -2\leq2\\g(-2)=-(-2+1)^2+1=0\\

(b)g(x)=-(x+1)^2+1, -2\leq -1\leq2\\g(-1)=-(-1+1)^2+1=1\\

(c)g(x)=2, x>2\\Therefore, g(4)=2
