mote1985 [20]

Answer:

36 ft

Step-by-step explanation:

Daniela facing a 12 ft tall statue that is 15 ft away. She can see the reflection of the top of the statue in a puddle on the ground 5 ft in front of her. How tall is Daniela?

Hence, this is calculated as:

5ft/15ft = 12 ft/Daniela's height

Cross Multiply

5ft × Daniela's height = 15ft × 12ft

Daniela's height = 15ft × 12 ft/5ft

= 36ft

Therefore, Daniela's height = 36 ft

What is an explicit equation?
artcher [175]
An explicit equation is an equation used to find a term in a sequence without using the any previous terms. For example, if I have the set of numbers 1, 3, 5, 7, 9, my explicit equation is F(n)=2(n-1)+1. If I plug 1 in for n, I get F(1)= 2(0)+1, which is 1, my first term.

Hope this made sense.

Yoshiko collected some bottle sto be recycled. Twelve were brown. There were 50 more clear bottles than brown ones. There were 3
snow_lady [41]
So we know there are 12 brown ones
brown=12
50 more than 12 is the number of clear bottles so 50+12=62

brown=12
clear=62

30 numbers down from 62 is the number of green ones so 62-30=32

brown=12
clear=62
green=32

12+62+32=106

so Yoshiko collected 106 bottles

What is the average rate of change of f(x), represented by the table of values, over the interval [-3, 4]? x f(x) -6 27 -3 6 -1
USPshnik [31]

Answer:

<em>The correct option will be:  C.  3</em>

Step-by-step explanation:

The given table is..........

x :      -6      -3      -1      0      1      4

f(x) :  27     6      2      3      6     27

<u>The formula for average rate of change</u> is:   \frac{f(b)-f(a)}{b-a} , where [a,b] is the given interval.

Here the interval is [-3, 4]. So,  a=-3 and b=4

Now, plugging the values of a and b into the above formula, we will get........

\frac{f(4)-f(-3)}{4-(-3)}

<u>From the given table,</u> we will get  f(4)=27 and f(-3)=6

So, the average rate of change will be:  \frac{27-6}{4-(-3)}= \frac{21}{7}=3
