Answer:

Step-by-step explanation:

What this proves is that teachers shouldn't assume that people can figure out how the calculator displays things. Time should be taken so you'd know the answer from class.

The two answers you want are the second one form the bottom and the third one from the top.

The third one from the top is 8*10^3

10^3 = 10 * 10 * 10 = 1000

8 * 10^3 = 8 * 10 * 10 * 10 = 8000

8000 is the answer written as a number.

All three are the same thing 8E3 means 8 * 10^3 = 8000

Identify sinJ as a fraction and as a decimal rounded to the nearest hundredth.

KiRa [710]

In the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.

In trigonometry, for a right triangle, the sine (sin) of any angle θ is given as the ratio of its opposite side to the hypotenuse of the triangle, that is, sin θ = (opposite side)/(hypotenuse).

In the question, we are asked to find the trigonometric ratio, sin J, for the given right triangle JKL.

The side opposite to angle J is KL, which has a value of 3 units.

The hypotenuse of the given right triangle is JK, which has a value of 7.8 units.

Thus, sin J can be calculated as:

sin J = KL/JK = 3/7.8 = 5/13 = 0.39.

Thus, in the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.

What is the domain and range of g(x)= -|x+2| -1

solmaris [256]

g(x)= -|x+2| -1

The domain is the input values, or x values

it is all real number

The range is the output values, or g(x)

the absolute value at is smallest is 0

0-1 is -1 this is the max since the absolute value is multiplied by -1

g(x) <=-1

the output is less than or equal to -1
