Answer:
196 in ^2
Step-by-step explanation:
Formula for area of trapezium is h ( a + b )/ 2 so.....
14(10 + 18)/2=196
61/100, because if it is 0.(value) than it is value / 100 assuming value is 2 digits long. We cannot simplify it further because 61 is prime number.
The next logical letter would be w.
This pattern starts at the first letter, then the last letter, then the second letter, then the second to last, the third, third to last, and so on.
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Answer:
The area of the larger frame is 300 square inches
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
In this problem the ratio of the perimeters is 3:5
so
The scale factor is 3/5
step 2
Find the area of the larger frame
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the smaller frame
y ----> the area of the larger frame
so

we have


substitute


solve for y


therefore
The area of the larger frame is 300 square inches
