Line JM intersects line GK at point N Which statements are true about the figure? Check all that apply.

Likurg_2 [28]

we know that

Complementary angles are two angles whose sum is equal to $90$ °, while supplementary angles are two angles whose sum is equal to $180$ °.

Statements

case 1) GNJ is complementary to JNK

Is False

Angle GNJ is $90$ degrees and angle JNK is $90$ degrees. The sum of the angles GNJ and JNK is $180$ degrees. Therefore, GNJ is not complemetary to JNK.

$angle\ GNJ+angle\ JNK=180\ degrees$

GNJ is supplementary to JNK, not complementary

case 2) MNL is complementary to KNL

Is True

The sum of angles MNL and KNL is MNK which is $90$ degrees. Therefore, MNL is complementary to GNJ.

$angle\ MNL+angle\ KNL=90\ degrees$

MNL is complementary to KNL

case 3) MNG is complementary to GNJ

Is False

Angle MNG is $90$ degrees and angle GNJ is $90$ degrees. The sum of the angles MNG and GNJ is $180$ degrees. Therefore, MNG is not complemetary to GNJ.

$angle\ MNG+angle\ GNJ=180\ degrees$

MNG is supplementary to GNJ, not complementary

case 4) KNJ is supplementary to MNL

Is False

Angle KNJ is $90$ degrees and angle MNL is less than $90$ degrees. The sum of the angles KNJ and MNL is less than $180$ degrees. Therefore, KNJ is not supplementary to MNL

$angle\ KNJ+angle\ MNL < 180\ degrees$

case 5) GNM is supplementary to JNK

Is True

Angle GNM is $90$ degrees and angle JNK is $90$ degrees. The sum of the angles GNM and JNK is $180$ degrees. Therefore, GNM is supplementary to JNK.

$angle\ GNM+angle\ JNK = 180\ degrees$

GNM is supplementary to JNK

therefore

the answer is

MNL is complementary to KNL

GNM is supplementary to JNK

A city's population increases by 5% every year. If its population today is 300,000, write a function that models the population

ratelena [41]

Answer:

f(x) = 300,000(1.05)^x

Step-by-step explanation:

Use the exponential growth equation:

f(x) = a(1 + r)^x

Plug in 300,000 as a, since it is the original population:

f(x) = 300,000(1 + r)^x

The city's population is growing at 5% each year, so plug in 0.05 as r:

f(x) = 300,000(1 + 0.05)^x

f(x) = 300,000(1.05)^x

So, the function for the population growth is f(x) = 300,000(1.05)^x

*brainliest for best answer thank you* Solve for b.

vekshin1

Hello from MrBillDoesMath!

Answer:

The fourth choice, b = +\- sqrt( sg + a^2)

Discussion:

s = (b^2 - a^2)/g => multiply both sides by "g"

sg = b^2 - a^2 => add a^2 to both sides

sg + a^2 = b^2 => take the square root of each side

b = +\- sqrt( sg + a^2)

which is the fourth choice.

Thank you,

MrB
