H(d)=height from water
when he reaches the water, his height from water=0

so set the equation equal to zero and solve

0=-d^2+2d+24
multiply both sides by -1 for ease
0=d^2-2d-24
now find what 2 factors of -24 add up to -2
answer is -6 and 4
0=(d-6)(d+4)
set each to zero
d-6=0
d=6

d+4=0
d=-4
you cannot have negative distance  because that means he hasn't jumped yet so get rid of this number

d=6

answer is 6 meters

Answer:

<h2>a) 24.39</h2><h2>b) 13.78</h2><h2>c) 7.92</h2><h2>d) expanding the business.</h2><h2>h) \frac{1}{5}</h2>

Step-by-step explanation:

a) The growing percentage for delivery of packages is \frac{5.1 - 4.1}{4.1} \times100 = \frac{10\times100}{41} = 24.39

b) The required percentage is \frac{454000 - 399000}{399000} \times100 = \frac{55000}{399000}  \times100 = 13.78(approximately)

c) Delivery vehicles has grown by \frac{119000 - 101000}{101000} \times100 = \frac{8000}{101000} \times100 = 7.921(approximately)

d) As it is cleared that UPS has increased the values with time, it can be possible that It was expanding with time.

e), f) and g) has shown in the given image.

h) The slope is \frac{5.1 - 4.1}{2017 - 2012} = \frac{1}{5}

Here the slope means the change of number of packages with time.

Answer:

11/40 + 1/4 + 1/20

Step-by-step explanation:

Draw a Venn diagram: (as shown)

Consumer Ed. : 22-4=18

French             : 20-4=16

Neither            : 80-18-16-4=42

Using probability notation where P(A) means probability of event A occurring.

P(Consumer Ed.) = 22/80

P(French) = 20/80

P(Both) = 4/80

<em>'or ' </em>in the question means you add.

=> 22/80 + 20/80 + 4/80

=> 11/40 + 1/4 + 1/20
