Answer:
B) The domain is all integers 0 or greater.
Answer:
= 3 3/4 m^2
or 15/4 m^2
Step-by-step explanation:
The base is the triangle.
A =1/2 bh
A = 1/2 (3 1/3 * 9/4)
Change 3 1/3 to an improper fraction (3*3+1)/3 = 10/3
A = 1/2 * 10/3 *9/4
Re arranging
= 1/2* 9/3 * 10/4
= 1/2 (3) 5/2
=15/4
Now writing as a mixed number
= 3 3/4 m^2
a) your iterative rule would be: 22,28,34,40....... it is because there are 22 in first row and it is increasing by 6 at each step....
b) Now, a(n) = 100, a=22, d=28-22 = 6
we know, a(n) = a+(n-1)d
100 = 22+(n-1)6
100-22 = 6n-6
78+6 = 6n
n = 84/6
n= 14
b) 11 units, 10.2 units
c)4.9 units, 15.8 units
d)4.9 units, 14.2 units
e)5.2 units, 14.1 units
The length of the legs of a right triangle in which one acute angle measures 19° and the hypotenuse is 15 units are 4.9 units and 14.2 units.
A right angle triangle has one of its angles as 90 degrees. The sides can be found using pythagoras theorem or trigonometric ratios.
Therefore,
sin 19 = opposite / hypotenuse
sin 19 = h / 15
cross multiply
h = 15 sin 19
h = 4.88352231686 = 4.9 units
Hence,
cos 19 = adjacent / hypotenuse
cos 19 = x / 15
cross multiply
x = 15 cos 19
x = 14.182778634 = 14.2 units
Therefore, the other legs are 4.9 units and 14.2 units.
