2.7
Step-by-step explanation:
Answer: <em>S</em> ≈ 48.2°
Step-by-step explanation:
We can use trigonometry functions to solve.
Looking at angle <em>S</em>, t = 18 is the hypotenuse and r = 12 is the adjacent side. This means we can use the cosine function.



Answer:
4y = -3x +30
Firstly you have to look for the gradient or slope using the points given in the question.
Then substitute the gradient (m) into y= mx+ c
I think it would a minimum because its positive. and the vertex would be (-.77,4.55) the minimum is 4.55
Step-by-step explanation:
Hi, I think correct variant is B
(28÷7)+7=4+7=11
