Answer:9
Because,
Two number six’s is twelve.
And if you add twelve and negative three it would equal nine
Or subtract three from twelve
Answer:
The answer to your question is:
a) sinФ = -4/√17
b) cosФ= 1/√17
c) tanФ = -4
Step-by-step explanation:
Just draw a right triangle where the opposite leg is -4/√17 the adjacent leg is 1/√17 and the hypotenuse is 1.
then sine Ф = opposite / hypotenuse = -4/√17 / 1 = -4/√17
cosine Ф = adjacent /hypotenuse = 1/√17 / 1 = 1/√17
tan Ф = opposite / adjacent = -4/√17 / 1/√17 = -4/1
(I) $ 846
(II) 157.64 cm²
Step-by-step explanation:
(I)
The area of the rectangle is;
720 * 500 = 360,000
10,000 m2 = 1 hectare
Therefore to convert the area to hectare;
360,000 / 10,000
= 36
If the cost of spraying the pesticide is $23.50 per hectare, then total cost is;
36 * 23.50
= 846
(II)
To find the area of the trapezoid;
(sum of the parallel sides * height) / 2
Height is the diameter of the circle – 21 cm
((19 + 29)*21) / 2
= 504
Then the area of the circle;
πr²
π * (21/2)²
= 346.36
The shaded area;
Area of the trapezoid – area of the circle
504 – 346.36
= 157.64
