What is the length of the dotted line in the diagram below? Leave your answer in simplest radical form.

Pachacha [2.7K]

Answer:

$\sqrt{93}$

Step-by-step explanation:

8^2+5^2=c^2

64+25=c^2

89=c^2

c= $\sqrt{89}$ <-- this is the length of the rectangle at the bottom

2^2+( $\sqrt{89}$ )^2=c^2

4+89=c^2

c= $\sqrt{93}$ <-- length of dotted line (diagonal)

If f(1) = 10 and f(n) = f(n = 1) – 4 then find the value of f(5).

svetoff [14.1K]

Given:

$f(1)=10$ and $f(n)=f(n-1)-4$ .

To find:

The value of f(5).

Solution:

We have,

$f(n)=f(n-1)-4$

For $n=2$ ,

$f(2)=f(2-1)-4$

$f(2)=f(1)-4$

$f(2)=10-4$

$f(2)=6$

For $n=3$ ,

$f(3)=f(3-1)-4$

$f(3)=f(2)-4$

$f(3)=6-4$

$f(3)=2$

For $n=4$ ,

$f(4)=f(4-1)-4$

$f(4)=f(3)-4$

$f(4)=2-4$

$f(4)=-2$

For $n=5$ ,

$f(5)=f(5-1)-4$

$f(5)=f(4)-4$

$f(5)=-2-4$

$f(5)=-6$

Therefore, the value of $f(5)$ is $-6$ .

(a+b)2 ;a=1/2 and b=2

FrozenT [24]

Answer:

$\frac{25}{4}$

Step-by-step explanation:

a + b = $\frac{1}{2}$ + 2 = 2 $\frac{1}{2}$ = $\frac{5}{2}$ , thus

(a + b)² = ( $\frac{5}{2}$ )² = $\frac{5}{2}$ × $\frac{5}{2}$ = $\frac{5(5)}{2(2)}$ = $\frac{25}{4}$
