Answer:

TRUE

Step-by-step explanation:

Two circles are congruent if they are equal in term of size. You can measure the size by comparing their diameter, radius or circumference. If two circles have the same radius, then they are said to be Congruent.

Therefore, the statement is TRUE ✅

How to translate f(x)=ln(8-x) into g(x)=lnx

Andreyy89

Step-by-step explanation:

f (x) + n → shifts the function n units upward.

f (x) – n → shifts the function n units downward.

f (x + n) → shifts the function n units to the left.

f (x – n) → shifts the function n units to the right.

–f (x) → reflects the function in the x-axis.

f (–x) → reflects the function in the y-axis.

$f(x)=\ln(8-x)=\ln\bigg(-(x-8)\bigg)\\\\h(x)=f(x+8)=\ln\bigg(-(x-8+8)\bigg)=\ln(-x)\\\\g(x)=h(-x)=\ln\bigg(-(-x)\bigg)=\ln(x)$

STEP 1:

shift the graph 8 units to the left

STEP 2

reflect the graph in the y-axis

Applying the inscribed angle theorem, we have the following measures:

a. Measure of angle RQT = 79°

b. Measure of angle QTS = 51°

<h3>What is the Inscribed Angle Theorem?</h3>

Based on the inscribed angle theorem, the measure of an inscribed angle (i.e. angle RQT and angle QTS) of a circle is half the measure of each of their respective intercepted arcs (arc RQT and arc QRS).

Given the following:

Measure of arc RQT = 202°

Measure of angle QRS = 129°

a. Find the measure of angle RQT:

Measure of angle RQT = 1/2(360 - 202) [inscribed angle theorem]

Measure of angle RQT = 1/2(158)

Measure of angle RQT = 79°

b. Find the measure of angle QTS:

Measure of angle QTS = 1/2(360 - 2(measure of angle QRS)) [inscribed angle theorem]

Measure of angle QTS = 1/2(360 - 2(129))

Measure of angle QTS = 1/2(102)

Measure of angle QTS = 51°

In summary, applying the inscribed angle theorem, we have the following measures:

a. Measure of angle RQT = 79°

b. Measure of angle QTS = 51°

Paul [167]

Answer:

No, although the random and large counts conditions are met, the 10% condition is not met.

Step-by-step explanation:

The random condition is met because the student selects a random sample of 50 seniors. The large counts condition is met because there are 38 expected successes and 12 expected failures, which are both at least 10. The 10% condition is not met because n = 50 is not less than 10% of the size of the population (N = 274 seniors).

What is the length of the radius of a circle with a center at 2 + 3i and a point on the circle at 7 + 2i?

dem82 [27]

You can calculate the difference/vector of both points:
$7+2i-(2+3i)=5-i$
then calculate the magnitude/length like pythagoras
$radius=\sqrt{5^2+(-i*-i)}\\=\sqrt{5^2+i^2}\\=\sqrt{5^2-1}\\=\sqrt{24}\\=\sqrt{4*6}\\=2*\sqrt{6}$
