Answer:
Option a is right.
Step-by-step explanation:
Parent funciton is
The new graph is
Since there is no change for x, there is no horizontal shift.
BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.
Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2
Option a is right
i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.
Answer:
105.12 ft²
Step-by-step explanation:
Let's first find the area of the rectangle.
ft², so the rectangle has an area of 80ft².
To find the area of the semi-circle, we find the area of a whole circle and divide by two.
The formula to find the area of a circle is 
. The radius is 4, as the diameter is 8.
Add 80 and 25.12:
Hope this helped!
Answer:
yeah your right
Step-by-step explanation:
Answer:
The null hypothesis is: u >= 1300 KN/m^2
And the alternative hypothesis is:
u < 1300 KN/m^2.
Step-by-step explanation:
The null hypothesis describes hat there is no difference or assiciation between variables of a specific population or that it is a particular average value while the alternative hypothesis states otherwise.
In this case study, the null hypothesis is: u >= 1300 KN/m^2
And the alternative hypothesis is:
u < 1300 KN/m^2.
Answer:
1933
Step-by-step explanation:
9 x (1 + 345) - 6 - 8 + 48 x 23 - 77
Use BODMAS method to solve these type of equation
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
_________________________________________________________
Brackets - 1 + 345 = 346
Multiplication
9 x 346 = 3114
48 x 23 = 1104
Lets rewrite the equation now
3114 - 6 + 1104 - 77
Addition
6 + 1104 = 1110
Subtraction
3114 - 1104 = 2010
2010 - 77 = 1933
Answer = 1933
