Answer:

\frac{27}{8}

Step-by-step explanation:

\left(\frac{16}{81}\right)^{\frac{-3}{4}}=\frac{16^{\frac{-3}{4}}}{81^{\frac{-3}{4}}}

=\frac{2^{-3} }{3^{-3} }

=\frac{\frac{1}{8}}{\frac{1}{27}}

=\frac{1*27}{8*1}

=\frac{27}{8}

Two mountain bikers take off from the same place at the same time. One travels north at 4 mph, and the other travels east at 3 m
Dafna1 [17]

Answer:

20 miles (Answer B)

Step-by-step explanation:

The northbound biker travels (4 mph)(4 hr) = 16 mi, and

the eastbound biker travels (3 mph)(4 hr) = 12 mi.

They travel at right angles to one another.  Thus, the Pythagorean Theorem applies here.  The distance between the two bikers is d = √( [12 mi]^2 + [16 mi]^2 ), or √(144 + 256) mi, or √400 mi, which works out to 20 miles.

Answer B is correct.

Compute the product AB by the definition of the product of​matrices, where Ab1 and Ab2 are computed​ separately, and by the​row-
nasty-shy [4]

Answer:

A * B = \left[\begin{array}{ccc}10&-6\\8&5\\19&-10\end{array}\right]

Step-by-step explanation:

Given

A =\left[\begin{array}{cc}2&-2\\3&4\\4&-3\end{array}\right]

B = \left[\begin{array}{cc}4&-1\\-1&2\end{array}\right]

Required

AB

To do this, we simply multiply the rows of A by the column of B;

So, we have:

A * B = \left[\begin{array}{ccc}2*4 + -2*-1&2*-1+-2*2\\3*4+4*-1&3*-1+4*2\\4*4-3*-1&4*-1-3*2\end{array}\right]

A * B = \left[\begin{array}{ccc}10&-6\\8&5\\19&-10\end{array}\right]
