4. - 4 < - 3

On the number line values further to the left are less than values to the right of them.

5(a) √701 = 26.47640459

(b) 26.5 (to 1 decimal place)

when rounding to 1 dec. place if the value in the second decimal place ≥ 5 then round up. If second decimal place < 5 then leave as is

here 7 ≥ 5 so round up

How do you find a missing side of a triangle using SOH CAH TOA

katrin2010 [14]

Answer:

See explanation and attachment

Step-by-step explanation:

SOH CAH TOA is a mnemonic.

SOH means $\sin \theta=\frac{Opposite}{Hypotenuse}$

CAH means $\cos \theta =\frac{Opposite}{Hypotenuse}$

TOA means $\tan \theta=\frac{Opposite}{Adjacent}$

Given an angle and a side of a right angle triangle, you can use the appropriate ratio to find the missing side.

For instance, find x in the diagram in the attachment.

In this case the best ratio to use is TOA.

$\tan 60\degree=\frac{\sqrt{3} }{x}$

$\implies x=\frac{\sqrt{3} }{\tan 60}$

$x=\frac{\sqrt{3} }{\sqrt{3} } =1$

All the other ratio also follow the same pattern

NB: Your calculator in degree should give $\tan 60\degree=\sqrt{3}$

If the area of a rectangle is x^2-9 and one dimension is x-3. what would be the other dimension?

Law Incorporation [45]

Answer:

Step-by-step explanation:

x2-9 = 0

Area of one dimension = x-3= 0

So, x2= 9

Square root on both sides;

x= +3 and -3

x-3 is one side

x+3 is the other dimension
