Which number produces a rational number when added to 0.25

Mathematics
1 answer:
Tatiana [17]3 years ago
8 0

0.65 is the correct one if not up there try 0.45 other possible one

Step-by-step explanation:

A rational number is defined as any number which can be expressed in fractional p/q of two integers, where 'p' is the numerator and 'q' is the denominator. 'q' can never be zero. A rational number can also be expressed as a terminating decimal. So, when 0.25 is added in 0.45 it becomes 0.65 which is rational.

What will be the maximum height <br><br> h (t)=-16t^2+128t+320
Korvikt [17]
To determine the maximum height, h, from the given above. Differentiate the function and equate to zero. Then, determine the value of t. The value, when substituted to the original function, will give the maximum height. For this given, 
                                           dh(t)/dt = -32t + 128 = 0, t = 4

Substituting t = 4 to the original function gives 320. Thus, the maximum height is 320 units.

                R  x   t  = D

# to           X      3 = 3X

# Return   6      4 = 24

Simplify the expression 17c4. Show work please.
Damm [24]

The given expression is 17c^4

The meaning of term simplification is to break something into smaller parts.

If i am simplifying an integer it means i will break that integer into prime factors.

If i am simplifying an expression that is term containing a variable and constant we have to simplify Constant into prime factors and variable into lowest terms having degree 1.

17 c^4

Constant = 17 , which is a prime number.It can't be broken into prime factors.

c^4= c\times c\times c\times c\\\\17 c^4= 17 \times c \times c \times c\times c

2. If it is→→→ _{4}^{17}\textrm{C}=\frac{17!}{(4!)(17-4)!)}=\frac{17\times16\times15\times14\times 13!}{4\times3\times2\times1\times13!}

=17 \times 2\times5\times 14=238 \times 10=2380
