16- let x represent the number:


x+ (x+1)+(x+2)=100

collect like terms

3x+3=100

3x=97

x=~32 but we need an odd number so round to 31, since 33 would be too great

31+33+35=99

therefore, the three numbers are 31, 33, 35

What is the measurement of ∠BAC and ∠ABC? Explain your process of solving.
Paraphin [41]

Answer:

<BAC = 78

<ABC = 68

Step-by-step explanation:

The remote angles theorem states that when one extends a side of a triangle, the angle formed between the extension and one of the sides of the triangle is equal to the sum of the two non-adjacent angles inside the triangle. One can apply this theorem here and state the following,

<BAC + <ABC = <ACD

Substitute,

(5y + 3) + (4y + 8) = (146)

Simplify,

9y + 11 = 146

Inverse operations,

9y + 11 = 146

     -11     -11

9y = 135

/9      /9

y = 15

Now substitute this value back into the expressions to find the numerical measurement of (<BAC) and (<ABC),

<BAC = 5y + 3

5(15) + 3

78

<ABC = 4y + 8

4(15) + 8

68

F(x) =(x+3)2−1 G(x) =−2x2+8x+3 H (t) =−16t2+28t Part A: What are the x- and y-intercepts of the graph of the function f(x)? Iden
fgiga [73]
Part 1) 
we have that
F(x) =(x+3)²<span>−1

using a graph tool
see the attached figure N 1

we know that
t</span><span>he x-intercepts of the graph  is when y=0
the points are (-4,0) and (-2,0)

</span><span>the y-intercepts of the graph is when x=0 
the point is (0,8)

the graph is a vertical parabola that opens up
so
the vertex of the parabola is a minimum
the vertex is the point (-3,-1)

Part 2) </span>Write the function g(x) in the form y=a(x−h)²<span>+k . Write the equation for the line of symmetry for the graph of g(x)
</span>
we have that
G(x) =−2x²<span>+8x+3 
</span><span>Group terms that contain the same variable
</span>G(x) =(−2x²+8x)+3 
Factor the leading coefficient 
G(x) =-2*(x²-4x)+3 
<span>Complete the square. Remember to balance the equation 
</span>G(x) =-2*(x²-4x+4-4)+3 
G(x) =-2*(x²-4x+4)+3 +8
G(x) =-2*(x²-4x+4)+11

Rewrite as perfect squares

G(x) =-2*(x-2)²+11


the answer Part 2) is

G(x) =-2*(x-2)²+11

see the attached figure N 2

the equation for the line of symmetry for the graph of g(x) is the vertical line that passes through the vertex

the vertex is the point (2,11)
so
the equation for the line of symmetry is x=2

Part 3) we have that
H (t) =−16t²<span>+28t

see the attached figure N 3

</span><span>the total length of time, in seconds, it took the dolphin to complete one jump is the difference for t=0 sec  and t=1.75 sec
(1.75-0)=1.75 sec

the answer Part 3) is 1.75 sec</span>
