Answer:
20 in³
Step-by-step explanation:
Area of a triangle is half the base times the perpendicular height:
A=0.5bh
=0.5*10*4
=20
QUESTION 10:
- The long edge of the paper is 11 inches long
- The frame is 4 long edges long
4 times 11 = 44 inches.
Now for the feet calculation!
- 1 foot = 12 inches
44 inches divided by 12 inches is 3 2/3 feet.
RESULT:
Cameron's poster frame is 44 inches long and 3 2/3 feet (OR 3.66666667 feet).
QUESTION 11:
- First, convert 3 yards into feet.
- 1 yard = 3 feet
- 3 yards = 9 feet
- 9 feet plus 2 feet = 11 feet.
- Converting feet into inches means multiplying the number of feet by 12 (since every foot has 12 inches)
-11 feet times 12 = 132 inches.
RESULT:
Use my explanation to determine that 3 yards and 2 feet = 132 inches.
Chain rule:
if
y=y(u) and u=u(x)
The dy/dx=(dv/du)(du/dx)
In our case
y=arcsin(u)
u=sin(x)
dy/du=1/√(1-u²) = 1/√(1-sin²x)
du/dx=cos x
dy/dx=cos x /√(1-sin²x)
Answer: dy/dx=cos x /√(1-sin²x)
Answer:
Cucumber (a)
Step-by-step explanation:
30 sprouts from 40 seeds is a ration of .75
checking the info in the table:
Cucumber .75
Marigold .83
Tomato .925
Watermelon .7
To find the ration divide sprouted amount by planted amount:
Cucumber 15/20 = .75
