Answer:
Perimeter = 19.6 cm
Area = 9.3 cm squared
Step-by-step explanation:
Perimeter: Add sides: 3.1 + 9.3 + 7.2 = 19.6
Area: 9.3 x 2 x 1/2 = 9.3
Answer:
The result is 
units.
Step-by-step explanation:
The coordinates for A and B:
A = (-2, 0)
B = (2, 2)
-To find the distance between A and B, you need the distance formula:
Where the first coordinate is 
and the second coordinate is 
.
-Use the coordinates A and B for the equation:
-Then, you solve the equation:
So, therefore the distance is 
units.
Answer:
x=40°
Step-by-step explanation:
(x-5)+(x+15)=90°
2x+10=90
2x=80
x=40°
Answer:
Mean= 4
Median= 3
Step-by-step explanation:
Mean
add all the numbers together (24)
and divide them by the number of numbers (6)
gives you 4
Median
put them in order from least to greatest
2,2,2,4,7,7
2,2 2,4 7,7
it leaves you between 2 and 4
which the middle is 3
so there
Answer:
Step-by-step explanation:
diagram attached represents a function g(x).
Circle (1) (circle on the left) represents the set of domain (input values) and circle (2) represents the range (output values).
a). For input value x = 7, out put value of the function is y = 9.
Therefore, g(7) = 9 will be the answer.
b). Range of the function g(x) is the set of output values.
Range: {12, 9, 9, 17}
c). Inverse of the function g(x) will have,
Domain: {12, 9, 9, 17}
Range: {4, 7, 10, 15}
For input value of x = 9, there are two output values y = 7, 10.
Since, "a function can't have two output values for the same input value".
Therefore, inverse of the function g(x) will not represent a function.
