Answer:

  D.  miles/hour

Step-by-step explanation:

The units analysis tells you the units are ...

  \dfrac{\text{m}}{\text{s}}\times\dfrac{\text{s}}{\text{h}}\times\dfrac{\text{mi}}{\text{m}}=\boxed{\dfrac{mi}{h}}

Units of meters and seconds cancel, leaving miles/hour.

If x(x - 5) = 14, then what is x equal to
Artyom0805 [142]

Answer:

x(x-5) = 14

x^2-5x-14 = 0

x^2 -7x+2x-14=0

x(x-7)+2(x-7)=0

(x+2)(x-7)=0

x = -2, 7

Hope this helps!

Criteria are the goals that a design must achieve. They are determined by what you want the cup to do. Criteria for the volume o
hichkok12 [17]

Answer:

Criteria for my Cup:

I want my cup to be short and wide.

Step-by-step explanation:

a) By the way, a cup can be measured in volume.  There are no tall and skinny cups.  They are not attributes of a cup.  However, a cup can be short (height).  It can also be wide, usually measured in diameter and radius.

b) Data:

Volume          cubic centimeters     milliliters    fluid ounces     cups

cold pack                   150                      150                 5               0.6

drink compartment  600                     600               20               2.5

total                           750                     750               25                3.1

Find the absolute maximum and minimum of the function f(x)=sin^2x+cosx
rosijanka [135]
Hello : 
f(x) = sin²(x) +cos(x)
the dirivate is : f'(x) = 2sin(x) cos(x) -sin(x) because : 
( sin²(x) )' =  2sin(x) cos(x)   and (cos(x))' = - sin(x)

f'(x) = 0  :  sin(x) (2cos(x) - 1) = 0
sin(x) = 0 : x = k <span>π    k in Z
</span>2cos(x) - 1 =0 : 2cos(x) =1
 cos(x) = 1/2 = cos( π /3)
 x =  π /3 +2k π  or   x = - π /3 +2k π 
in intervall : <span> <span>[0 , 2π] : 
k=0 : x= 0   f(0) = 1   ( </span></span>minimum<span>)
</span>k=1 :  x = π    f(π) = -1 (<span>minimum)
x= </span> π /3  f (  π /3 ) = 1.25 ( <span>maximum)</span>

The probability of tossing heads with a standard coin is 1/2, because it is one of two possible outcomes. The probability of tos
spayn [35]

Answer:

  a) 1/64

  b) 1/4096

Step-by-step explanation:

As you can tell from the example, the exponent of 1/2 is the number of heads in a row.

a) p(6 heads in a row) = (1/2)^6 = 1/(2^6) = 1/64

b) p(12 heads in a row) = (1/2)^12 = 1/(2^12) = 1/4096

_____

<em>Additional comment</em>

The probability of a head is 1/2 because we generally are concerned with a "fair coin." That is defined as a coin in which each of the 2 possible outcomes has the same probability, 1/2. Similarly, a "fair number cube" has 6 faces, and the probability of each is defined to be the same as any other, 1/6. Loaded dice and unfair coins do sometimes show up in probability problems.

someone help on the "how did basil know" part before i sue and quit school. i just wanna sleep it's 12 am.
PtichkaEL [24]
Well, the last digit in the product will only come from the last digits of the numbers that you're multiplying together. So for 0.303 & 4.48, that last digits are 3 & 8 so that last digit in the product would come from
3 \times 8 = 24
So 4. There are only two options that end in 4, 1.35744 & 0.13574. You can by the magnitude of the numbers that it isn't as small as 0.13574 so the answer must be 1.35744.
