Answer: 14

Step-by-step explanation:

Since it is a right angles triangle , Pythagoras theorem will come into play,which states that;

the square of the hypotenuses = square of the adjacent + square of the opposite , that is

$22^{2}$ = $(RT)^{2}$ + $17^{2}$

Therefore:

$(RT)^{2}$ = $22^{2}$ - $17^{2}$

$(RT)^{2}$ = 484 - 289

$(RT)^{2}$ = 195

RT = $\sqrt{195}$

RT = 13.96

RT≈ 14

Answer:

c)14

Step-by-step explanation:

Pythagorean theorem:

TR² + RG² = TG²

TR² + 17² = 22²

TR² = 22² - 17² =(22+17)(22-17)

= 39*5 = 195 ≈ 196

TR =√196 = 14

A (103)(109)

=103*109

=(10*10*10)*(10*10*10*10*10*10*10*10*10)

=10*10*10*10*10*10*10*10*10*10*10*10

Trava [24]

Answer:

M(t) = M(16 - 2·t)

Step-by-step explanation:

The function is just formed by using the concept of composite functions.

B is cups of blueberries, and n is cups of blueberries,

So by substituting values the required equations formed are given by :

B(t) = 2·(8 - t)

M(n) = 12·n

n = B(t)

M(t) = M(n)

= M(B(t))

= M(2·(8 - t))

= M(16 - 2·t)

Therefore, this is the required function muffins M
