$\huge\text{Hey there!}$

$\mathsf{\dfrac{(-2^3)(3^2)}{6}+(-2^2)(3^2)}$

$\mathsf{(-2)^3=\bf -8}$

$\mathsf{= \dfrac{-8(3^2)}{6}+(-2^2)(3^2)}$

$\mathsf{3^2=\bf 9}$

$\mathsf{= \dfrac{(-8)(9)}{6}+(-2^2)(3^2)}$

$\mathsf{-8(9)= \bf -72}$

$\mathsf{= \dfrac{-72}{6}+(-2^2)+(3^2)}$

$\mathsf{\dfrac{-72}{6}=\bf -12}$

$\mathsf{= -12+(-2)^2(3^2)}$

$\mathsf{-2^2=\bf 4}$

$\mathsf{= -12+4(3^2)}$

$\mathsf{3^2=\bf 9}$

$\mathsf{= -12+4(9)}$

$\mathsf{4(9)= \bf 36}$

$\mathsf{-12 + 36 = \bf 24}$

$\boxed{\boxed{\large\text{Answer: \huge\bf Option C. 24}}}\huge\checkmark$

Pls help pefer if you can somewhat explain (Grade 11) (ASAP) (Urgent)

Vesna [10]

Answer:

17) h=I(1-cosθ); 18) h=1.404.

Step-by-step explanation:

17) h=I-BC;

In ΔABC: m(∠C)=90°, m(∠B)=θ, AB=I, then BC=AB*cos(∠B); ⇒ BC=Icosθ;

Then h=I-Icosθ or h=<u>I(1-cosθ)</u>.

18) if I=6 and θ=40°, then h=6(1-cos40°)≈6*(1-0.766)=<u>1.404</u>, where cos40°≈0.766.

For more details see the attachment.
