Answer:

i'm not sure if this is what you are looking for, but g(x)=f(x) just means both are equivilent. The graphs whould look the same. :)

10. A wire is of length 264 cm. It is bent into a circle. What is the radius of the circle so obtained. If it

Luden [163]

Answer:

$r = 42$ --- radius

$L = 66$ -- Length of the square

Step-by-step explanation:

Given

$Length = 264cm$

Solving (a): Find the radius (when it formed a circle).

The length of the wire represents the circumference (C) of the wire.

So, we have:

$C = 2\pi r$

Make r the subject

$r = \frac{C}{2\pi}$

Substitute 264 for C

$r = \frac{264}{2\pi}$

$r = \frac{132}{\pi}$

Take $\pi$ as 22/7

$r = \frac{132}{22/7}$

$r = \frac{132*7}{22}$

$r = \frac{924}{22}$

$r = 42$

Solving (b): Find the side length (when it formed a square).

The length of the wire represents the perimeter (P) of the wire.

So, we have:

$P = 4L$

Make L the subject

$L = \frac{1}{4}P$

Substitute 264 for P

$L = \frac{1}{4}*264$

$L = 66$

Jana knows that in ∆LET and ∆PVC, ET ≅ VC, ∠L ≅ ∠P and ∠E ≅ ∠V. Which congruence postulate or theorem can be used to prove that

LiRa [457]

Answer:

SAA theorem

Step-by-step explanation:

The given data with regards to ΔLET and ΔPVC are;

ET ≅ VC

∠L ≅ ∠P

∠E ≅ ∠V

From the given relationship, we have that two angles and the adjacent (nonincluded) side to the two angles in ΔLET are congruent to the corresponding two angles and adjacent (nonincluded) side of ΔPVC

Therefore, the congruence theorem that can be used to prove that the two triangles are congruent is the Side-Angle-Angle (SAA) congruency theorem

The SAA congruency theorem states that, two triangles that have two angles and a nonincluded side on one triangle being congruent to the corresponding two angles and a non included side on the other triangle, then the two triangles are congruent.

a person goes from a sauna at 115°F to an out side temperature of -30°F. what is the change in temperature?

Oksana_A [137]

Whenever you're interested in computing the (absolute) difference between two values of a certain variable, you have to subtract the final value and the initial value. This is often written as delta:

$\Delta x = x_{\text{final}} - x_{\text{initial}}$

So, in this case, the final temperature is -30°F. The initial temperature is 115°F. So, the variation is

$\Delta T = T_{\text{final}} - T_{\text{initial}} = -30 - 115 = -145$

A negative delta indicates that the value decreased, which is our case.
