Answer:
1A: 29 units²
1B: √29 units
2, 3, 4. see below
5. between 8 and 8.5
Step-by-step explanation:
1A: Split the given square up into 4 triangles and a square in the centre. You'll get 4 triangles of sides 5 and 2, and a centre square of sides 3.
Area = 4(0.5)(5 x 2) + (3²) = 29 units²
1B: Square root your answer in 1A. √29 units
Alternatively you can use Pythagoras' theorem on one of the triangles. √(5² + 2²) = √29 units
2. The area is exactly 17 units, because the area of a square is the length of its side squared. (√17)² = 17, hence the square's area is 17 units.
3. A number that can be expressed as a fraction (includes whole numbers). E.g. 1/2, 1/7, 4
4. A number that cannot be expressed as a fraction. E.g. π, e, √3
5. Consider the closest square numbers to 70. 70 is closer to 64 than 81 (difference of 6 vs 11). Hence √70 should be closer to 8 than 9. Your answer should be between 8 and 8.5.

Step-by-step explanation:
Answer: 1,069,200
Step-by-step explanation:
We know that they paid 1.32 million and was 19% above what they paid in 2007.
Since they paid 19 percent above (1.19) 2007 we can reverse and do 0.81 * 1,320,000 to get our answer.
You may be wondering why it's 0.81 instead of 0.19 that is because 1.19 is over 1. Since 100 is equal to a whole we subtract 0.19 from 100 to get our value we multiply by.
1,320,000 * 0.81 = 1,069,200
We can also find the different simply by doing 1,320,000 * 0.19 which equals 250,800 and to get our answer from here we just subtract 1,320,00 by 250,800
Answer:
sin=0
cos=-1
tan=0
csc=undefined
sec=-1
cot=undefined
Step-by-step explanation:
On the unit circle, 
. The sin of theta is therefore 0, the cosine is -1, and the tangent is 0/-1=0. Since the following functions are just the reciprocals of the previous ones, the cosecant is 1/0=undefined, the secant is 1/-1=-1, and the cotangent is 1/0= undefined. Hope this helps!
