Please help me! I’m so confused!! I will give BRAINLIEST :) A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.

If angle BAC = 22 degrees the angle ABC = ?

Answers

Answer 1

Answer:

Answer:

136 degrees

Step-by-step explanation:

if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136

Answer 2

Answer:

Answer:

Angle ABC is equal to 136 degrees.

Step-by-step explanation:

Since sides AB and BC are congruent (meaning they are equal to each other), they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.

Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.

136 + 22 + 22 = 180, so this works!

I hope this helps!

Answer:

We know that range is the set of outputs that shown on the y-axis of the graph, so we must find the endpoints of the graph on the y-axis. When we look, we get the endpoints -6 and 10, so we know that this is the range, and so we represent this in an expression:

-6 < y < 10

The difference of two numbers is 20 and their product is 125 what is the answer

Answers

The value of the two numbers will be -25 and -5.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the difference between the two numbers is 20 and their product is 125. Let the two numbers are x and y.

x - y =20 or x = y + 20

xy = 125

Solve the equations,

y(y+20) = 125

y² + 20y -125 =0

y² +25y - 5y -125=0

y(y + 25) --5(y + 25) = 0

( y + 25 )( y - 5 ) = 0

y = -25 and y = 5

x = y + 20

x = -25 + 20

x = -5

Therefore, the value of the two numbers will be -25 and -5.

Your answer is D. (x + 2)

Answer:

Step-by-step explanation:

A patient is given a 50 mg dose of medicine. The medicine's effectiveness decreases every hour at a constant rate of 40%. What is the exponential decay function that models this scenario? How much medicine will be left in the patient's system after 2 hours?

Answers

It should be noted that only 60% of the medicine of the previous hour is left n the patient's system every hour. Thus, the model of the scenario is,

D = 50 mg (0.6^n)

where D is the dosage at any hour n.

Using the model above with n equal to 2. D becomes 18. Therefore, only 18 mg is left in the patient's system after 2 hours.

The quantity of the medicine left in the patient's system after 2 hours is 18 mg.

What is exponential growth or decay function?

Consider the function:

$y = a(1\pm r)^m$

where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

It should be noted that only 60% of the medicine of the previous hour is left n the patient's system every hour.

Thus, the model of the scenario,

$D = 50 ( 1 - 0.4)^n\n\nD = 50 (0.6^n)$
