if sum of the angle measures total 360, you see in the diagram that adding all of thme up should get you 360

2a + a + 2a + a = 360

6a = 360

a = 60

the angles are 60, 60, 120, 120

What is the domain of the function f(x)= e^x/e^x+c if c is a constant greater than 0

Viktor [21]

Answer: Option d.

Step-by-step explanation:

To find the domain of the function we should look for the values for which the denominator is equal to zero, because the division by zero is not allowed.

We know by definition that the function $e^x$ is always greater than zero for all x.

We know that the constant c is greater than zero (c>0).

Then, the expression $e^x+c$ is never equal to zero.

Therefore, it does not exist a value for x that makes the denominator 0. Then, the domain of the function is all real numbers.

The answer is the option d.

If a watermelon weighs 6 255 grams and a scales measures the weight 6 475 grams. What is the scales percent error

Liono4ka [1.6K]

Answer:scales percent error=3.51%

Step-by-step explanation:

P ercent error = Experimental value - Theoretical value /Theoretical value x 100

Theoretical value = 6255 grams

Experimental value ( use of scale ) = 6475grams

Percent error =(6475- 6255)grams / 6255grams x 100

=220/6255 x 100

=3.51%

Find two consecutive even natural number whose product is 168

Oduvanchick [21]

$2n(2n+2)=168\\
4n^2+4n-168=0\\
n^2+n-42=0\\
n^2+7n-6n-42=0\\
n(n+7)-6(n+7(=0\\
(n-6)(n+7)=0\\
n=6 \vee n=-7\\
-7\not \in \mayhbb{N}\\\\
2n=12\\
2n+2=14$

These numbers are 12 and 14.
