Answer:

  b) The measure of angle B is 117°.

Step-by-step explanation:

Angles A and C are vertical angles, so are congruent. Angles C and 27° total 90°, so ...

  ∠C = 90° -27° = 63° . . . . . not 53°

The measure of angle B is the supplement of angle A or C, so is ...

  ∠B = 180° -∠C = 180° -63°

  ∠B = 117°

Only choice B is correct.

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of in
erastova [34]

Answer: x= 187.5p

Step-by-step explanation:

Given : An equation relating packets to bytes of information : b = 1,500p where<em> p</em> represents the number of packets and <em>b</em> represents the number of bytes of information.

1 byte = 8 bits

Let x= Number of bits such that 1 b = 8x

Put b = 8x in given equation , we get

8x=1500p

Divide both sides by 8 , we get

x= 187.5p

Hence, the equation represent the relationship between the number of packets and the number of bits : x= 187.5p

What is the first derivative of r with respect to t (i.e., differentiate r with respect to t)? r = 5/(t2)Note: Use ^ to show exp
adelina 88 [10]

Answer:

The first derivative of r(t) = 5\cdot t^{-2} (r(t)=5*t^{-2}) with respect to t is r'(t) = -10\cdot t^{-3} (r'(t) = -10*t^{-3}).

Step-by-step explanation:

Let be r(t) = \frac{5}{t^{2}}, which can be rewritten as r(t) = 5\cdot t^{-2}. The rule of differentiation for a potential function multiplied by a constant is:

\frac{d}{dt}(c \cdot t^{n}) = n\cdot c \cdot t^{n-1}, \forall \,n\neq 0

Then,

r'(t) = (-2)\cdot 5\cdot t^{-3}

r'(t) = -10\cdot t^{-3} (r'(t) = -10*t^{-3})

The first derivative of r(t) = 5\cdot t^{-2} (r(t)=5*t^{-2}) with respect to t is r'(t) = -10\cdot t^{-3} (r'(t) = -10*t^{-3}).
