Can someone please tell me the degree measure of angles 1,2 3 and 4?
It’ll help even more if you explain.

Answers

Answer:

angle 1 is 42

angle 2 is 138

angle 3 is also 42

Step-by-step explanation:

for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal

for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces

for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42

this year Benny is 12 years old and his mom is 48 years old what percent of his mom's age is Benny's age ​

Answers

Answer:

25%

Step-by-step explanation:

Let's set up a percent proportion:

12/x = 48/100

To solve for x, we would do:

x = (12*100)/48 = 1200/48 = 25

x = 25%

In my opinion, the easiest way to do this would be to look at this and notice that 12 * 4 =48 so that means 12 is 1/4 of 48 and 1/4 = 25%.

Suppose there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 58.3°F​, what will be the temperature when the plane reaches an altitude of 2,000 ft​?

Answers

Answer: 55.1°F

Step-by-step explanation:

We are informed that there is a 1.6°F drop in temperature for every thousand feet that an airplane climbs into the sky, if the plane reaches an altitude of 2,000ft, the drop in temperature will be:

= 1.6° × 2

= 3.2°F

If the temperature on the ground is 58.3°F​, then the temperature when the plane reaches an altitude of 2,000 ft will be:

= 58.3°F - 3.2°F

= 55.1°F

Which parent function is represented by the graph?
5+
A. Linear parent function
A
B. Quadratic parent function
C. Absolute value parent function
D. An exponential parent function

Answers

Answer:

quadratic parent function

Step-by-step explanation:

squares cannot be negative no matter what you cannot square a number into a negative number which is why there are no negative y values because y is a function of X

The parent function is represented by the graph is an exponential parent function, the correct option is D.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The graph of function

Now,

To identify which parent function is represented by the graph, we can look at the shape and features of the graph. The graph shows a curve that starts from the lower left quadrant and rises rapidly as x increases. The graph passes through the point (0, 1) and has a horizontal asymptote at y = 0. These are the characteristics of an exponential parent function with a base greater than 1.

Therefore, the function will be an exponential parent function.
