Answer:

$\large\boxed{\{x\ |\ -\sqrt5\leq x\leq\sqrt5\}}$

Step-by-step explanation:

$x^2-5\leq0\qquad\text{add 5 to both sides}\\\\x^2\leq5\iff x\leq\sqrt5\ \wedge\ x\geq-\sqrt5\Rightarrow-\sqrt5\leq x\leq\sqrt5$

Suppose you are asked to find the area of a rectangle that is 2.1-cmcm wide by 5.6-cmcm long. Your calculator answer would be 11

Answer:

12 square cm correct to 2 significant figures

Step-by-step explanation:

Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm

To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.

The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.

11.76 square cm = 12 square cm correct to 2 significant figures

Answer:

y'= 5x^4 + 5^x In(5)

Step-by-step explanation:

Differentiate with Respect to x

f(x)'=5x^4 + In(5^x)

f(x)'= 5x^4 + x In(5)

with respect to x, we have

y'= 5x^4 + y In(5)

y'= 5x^4 + 5^x In(5)
