Answer:

9t + 8

Step-by-step explanation:

9t + (5+3)

Think of it like this. You have 9 oranges, 5 grapes, and 3 grapes. How many grapes and oranges do you have?

Math wise, we will have t representing oranges, and the normal numbers representing grapes. All you have to do is combine them using whatever sign separates them. If you need more help, let me know.

Need to get the values of each trig function using half angle formulas within the constraint

Marizza181 [45]

$\bf cot(u)=4\qquad \pi \ \textless \ u\ \textless \ \frac{3\pi }{2}\implies cot=\cfrac{-4}{-1}\cfrac{\leftarrow adjacent}{\leftarrow opposite}
\\\\\\
hypotenuse\implies \sqrt{(-4)^2+(-1)^2}\implies \sqrt{17}
\\\\\\
cos(\theta )=\cfrac{-4}{\sqrt{17}}\implies \cfrac{-4\sqrt{17}}{17}\\\\
-------------------------------\\\\
$

$\bf sin\left( \frac{u}{2} \right)=\pm\sqrt{\cfrac{1+\frac{4\sqrt{17}}{17}}{2}}\implies \pm\sqrt{\cfrac{\frac{17+4\sqrt{17}}{17}}{2}}\implies \boxed{\pm\sqrt{\cfrac{17+4\sqrt{17}}{34}}}
\\\\\\
cos\left( \frac{u}{2} \right)=\pm\sqrt{\cfrac{1-\frac{4\sqrt{17}}{17}}{2}}\implies \pm\sqrt{\cfrac{\frac{17-4\sqrt{17}}{17}}{2}}\implies \boxed{\pm\sqrt{\cfrac{17-4\sqrt{17}}{34}}}$

$\bf tan\left( \frac{u}{2} \right)=\pm\sqrt{\cfrac{\frac{17+4\sqrt{17}}{34}}{\frac{17-4\sqrt{17}}{34}}}\implies \boxed{\pm\sqrt{\cfrac{17+4\sqrt{17}}{17-4\sqrt{17}}}}$

You have to multiply 42x60 then add it to 35 then subtract the answer minus 10. Then multiply 60x5. Lastly you get both answers and add them I hope this is right

Answer:

Option D: (3, 5 , 7)

Step-by-step explanation:

From the given diagram:

f(x) = (1,3) , (2,5), (3,5), (4,5), (5,7)

So from the function given the range is:

f(x) = (3, 5, 7)
