Answer:

We can find the surface area of any pyramid by adding up the areas of its lateral faces and its base.

Surface area of any pyramid = area of base + area of each of the lateral faces

Example:A=lw+l(w2)2+h2+w(l2)2+h2=3·2+3·(2

2)2+82+2·(3

2)2+82≈46.46559

Jan is 2/3 of Karyn's age. Jan's age 8 years ago is 2/5 of Katyn's age 4 yeats from now. Jan is how many younger than Karyn?

Elden [556K]

Answer:

12 years younger.

Step-by-step explanation:

Let Jan's age be J and Karyn's age be K.

$J= \frac{2}{3} K$

Jan's age 8 years ago is 2/5 of Karyn's age 4 yeaRs from now.

$J-8 = \frac{2}{5} (K+4)$

=> $(\frac{2}{3} - \frac{2}{5} ) K = \frac{8}{5} + 8$

=> 4K = 48 X 3

=> K= 36.

=> J= 24.

So Jan is 12 years younger.

Please help!!!! the question is in screenshot

Answer:

$-\cos nw_0t$

Step-by-step explanation:

We can use the double angle identity for sine.

$\sin (A+B)=\sin A \cos B+\sin B\cos A$

The given expresion is

$\sin (nw_0t-90)$

We apply the identity to get:

$\sin (nw_0t-90)=\sin nw_0t \cos 90-\cos nw_0t \sin 90$

We simplify to obtain;

$\sin (nw_0t-90)=\sin nw_0t (0)-\cos nw_0t (1)$

This simplifies to:

$\sin (nw_0t-90)=-\cos nw_0t$ The correct answer is D
