To find the slope, you use the slope formula (m):
and plug in the two points
(-3, 4) = (x₁, y₁)
(2, -1) = (x₂, y₂)

[two negatives cancel each other out and become positive]


m = -1 The slope is -1
D, it increases then goes at a constant speed
Answer:
h(x) = -16x² + 192x + 208
784ft
6 sec
13 sec
Step-by-step explanation:
a)
h(x) = -16x² +vx + h
here v represent velocity
represent initial height of launch
h(x) = -16x² + 192x + 208
b)
h(x) = -16x² + 192x + 208
here a = -16
b = 192
c = 208
x = -b/2a
= -192/2(-16)
= 6
plug this value in the equation
h(x) = -16(6)² + 192(6) + 208
= 784ft
e)
Plug h(x)=0 in the equation
0 = -16x² + 192x + 208
divide equation by -16
x² - 12x - 13 = 0
Factors
1x * -13x = -13
1x - 13x = -12
Factorised form
x² - 12x - 13 = 0
x² + x - 13x - 13 = 0
x(x+1) -13(x+1) = 0
(x+1)(x-13) = 0
x = -1
x = 13
Since time can not be negative so we will reject x = -1
Answer: 5
Step-by-step explanation:
Answer:
At least 4 numbers of information is needed
The four are highlighted below in the explanation section
Step-by-step explanation:
1. Given that the shape has four right angles and that all its sides are congruent then it's a quadrilateral
2. If two sides are consecutively congruent it is a quadrilateral shape
3. If a rhombus contains a right angle, then it’s a square shaped rhombus
4. If a quadrilateral is both a rectangle and a rhombus, then it’s a square
