Answer:

$\mathsf {SA = 112 in.^{2} }$

Step-by-step explanation:

$\textsf {Formula used :}\\\implies \textsf {SA = 2(length * width + width * height + length * height) }$

$\textsf {Given :}\\\textsf {Length = 5 in.}\\\textsf {Width = 4 in.}\\\textsf {Height = 4 in.}$

$\textsf {Solving :}$

$\implies \mathsf {SA = 2 (5 * 4 + 4 * 4 + 5 * 4)}$

$\implies \mathsf {SA = 2 (20 + 16 + 20)}$

$\implies \mathsf {SA = 2 (56)}$

$\implies \mathsf {SA = 112 in.^{2} }$

Verify the identity. Show your work. 1 + sec^2xsin^2x = sec^2x

allsm [11]

$\bf \textit{Pythagorean Identities}
\\\\
1+tan^2(\theta)=sec^2(\theta)\\\\
-------------------------------\\\\
1+sec^2(x)sin^2(x)=sec^2(x)
\\\\\\
1+\cfrac{1}{cos^2(x)}\cdot sin^2(x)\implies 1+\cfrac{sin^2(x)}{cos^2(x)}\\\\\\ 1+tan^2(x)\implies sec^2(x)$

Minchanka [31]

Answer:

i did not understant your question

i think u want the definition of relation

A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.
