Answer:

c=\sqrt{65}=8.062.

Step-by-step explanation:

\text{Consider }  \bigtriangleup DBC, \text{by Pythagoras}\\DB^2+BC^2=DC^2 \\\Rightarrow  b^2=DC^2-BC^2\\\Rightarrow  b^2= 5^2-3^2=25-9\\\Rightarrow  b^2= 16\\\text{Then } , b=4.\\ \text{Consider }  \bigtriangleup DBA, \text{by Pythagoras}\\DB^2+BA^2=DA^2\\\Rightarrow c^2=b^2+BA^2\\\Rightarrow c^2=4^2+7^2\\\Rightarrow c^2=16+49\\\Rightarrow c^2=65\\\text{Then } , c=\sqrt{65}=8.062.

PLS EXPLAIN HOW THESE SEQUNCE IS FORMED<br><br>ALL ODD NUMBERS
scoundrel [369]

Answer:

7,21,27,81,87, 261, 267....

Step-by-step explanation:

All odd number series from the given figure is

7, 21, 27, 81 , 87....

We can write this series as

7, 7 x 3 , (7x3)+6, ((7x3)+6)x3, (((7x3)+6)x3)+6....

7, 21, 21+6 , 27 x 3, 81+6...

Now, the next term of the series will be

=((((7x3)+6)x3)+6) x 3

= 87 x 3

= 261

And another term of the series will be

= 261 +6

= 267

7,21,27,81,87, 261, 267....

In 2004, a magazine's circulation was about 1,000,000 readers. In 2014, the magazine had about 2,000,000 readers. Write a linear
Sever21 [200]

Answer:

m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000

And then we can use for example the first point (t_1, r_1) = (4, 1000000) to find the intercept:

1000000= 100000*4 + b

b=600000

So then the linear model for this case should be:

r = 100000 t + 600000

Step-by-step explanation:

For this case we want to find a linear model given by:

r =mt+b

Where r = represent the number of readers , t= years after 2000

m = the slope for the model and b the intercept

For this case we can define the following points from the data given:

(t_1, r_1) = (4, 1000000) 4 years after 2000

(t_2, r_2) = (14, 2000000) 14 years after 2000

We can find the slope with the following formula:

m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000

And then we can use for example the first point (t_1, r_1) = (4, 1000000) to find the intercept:

1000000= 100000*4 + b

b=600000

So then the linear model for this case should be:

r = 100000 t + 600000
