Answer:
1/16Step-by-step explanation:
(-32)^-4/5 =(-2^5)^-4/5 =(-2)^-(5*4/5) =(-2)^ -4=16^-1=1/16At the start of a race, a runner’s velocity changes from 0 to 4,0 m/s. It takes him 2 seconds to speed up. His
acceleration is ___ m/s2.
Please answer with a explanation if you can.
Answer:
2 m/s²
Step-by-step explanation:
Given:
v₀ = 0 m/s
v = 4.0 m/s
t = 2 s
Find: a
a = (v − v₀) / t
a = (4.0 m/s − 0 m/s) / 2 s
a = 2 m/s²
Answer:
At the start of a race, a runner’s velocity changes from 0 to 4.0 m/s. It takes him 2 seconds to speed up. His acceleration is 2 m/s2.
Explanation:
Acceleration is the rate at which velocity changes. To find the acceleration, divide the change in velocity (final velocity − initial velocity) by the time interval. In this example, the change in velocity is 4.0 m/s in 2 seconds. So, divide 4.0 by 2.
I hope this explanation helps you understand accelerations!

PLEASE HELP Complete the table below to find solutions to the linear equation y=5x+35.
When answering the third column (x,y), use parentheses and a comma but do not include a space between numbers.
Answer:
x | y | (x,y)
0 | 35 | (0,35)
3 | 50 | (3,50)
-7 | 0 | (-7,0)
Step-by-step explanation:
Given the equation: [tex] y = 5x + 35 [/tex], to complete the table, plug in the value of x given in the table in each row, to find y.
When x = 0,
[tex] y = 5(0) + 35 [/tex]
[tex] y = 0 + 35 [/tex]
[tex] y = 35 [/tex]
(0,35)
When x = 3,
[tex] y = 5(3) + 35 [/tex]
[tex] y = 15 + 35 [/tex]
[tex] y = 50 [/tex]
(3,50)
When x = -7,
[tex] y = 5(-7) + 35 [/tex]
[tex] y = -35 + 35 [/tex]

What is greater? X or -X and Why?
Step-by-step explanation:
A negative number(or variable, in this case) is less than 0. For example, which is greater, 3 or -3? 3, right?
In variables, x or a or m or whatever, can also be represented as 1x or 1a or 1m, and so on. So in the question, it's asking which is greater, x or -x? Think of the variables as 1x or -1x.
So 1x is greater.

An identification code is to consist of 4 letters followed by 2 digits. Determine the following
a) How many different codes are possible if repetition of letters is permitted, repetition of numbers is not permitted, and the first three entries must all be the same letter
b) How many different codes are possible if the first letter must be an A, B, C, or D and repetition is not permitted?
explanation
Counting Possibilities with Repetition or No Repetition:
Counting the number of possibilities in a given situation can vary quite a bit depending on whether repetition is allowed or not. For example, if trying to find how many 6 letter passwords can be made with 10 letter choices, if the letters are allowed to be repeated then there are 10 choices for each letter in the password - resulting in... 10 x 10 x 10 x 10 x 10 x 10 = 10^6 =1,000,000 possible passwords.
However, if repetition of letters is not allowed, then there are 10 choices for the first letter, but only 9 for the second, 8 for the third, and so on. This results in only 10 x 9 x 8 x 7 x 6 x 5 = 151,200
Answer :
There are 26 letters to choose from and 10 digits (0 through 9).
(a) If the first three entries must all be the same letter, then there are 26 choices for the first entry, but only one choice for the second and third entries. The fourth entry can then be any letter, so there are 26 possible choices for the fourth entry. The fifth and sixth entry must be digits, but repetition of numbers are not permitted. So the fifth entry has 10 choices and the sixth entry only has 9 choices. This is a total of 26 x 1 x 1 x 26 x 10 x 9= 60,840
b) If the first letter must be one of A, B, C, or D, then there are 4 choices for the first entry. No repetition is allowed, so the second entry must be chosen out of the 25 remaining letters, and similarly the third and fourth entry will have 24 and 23 choices each. The fifth and sixth entry must be digits, but repetition of numbers are not permitted. So the fifth entry has 10 choices and the sixth entry only has 9 choices. 4 x 25 x 24 x 23 x 10 x 9=4,968,000 different codes

Step-by-step explanation:
[tex] \sf{ \frac{2}{3} \times \frac{1}{4} \times x = 1360}[/tex]
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term
[tex] \longrightarrow{ \sf{ \frac{2 \times 1}{3 \times 4} \times x = 1360}}[/tex]

Which best explains how to subtract one integer from another?
Answer:
Option (3)
Step-by-step explanation:
Integers are the numbers which don't have a fractional part (having positive of negative notations)
Example; -2, -1, 0, 1, 2,...
Let the two integers are 0 and 2,
Subtraction of these integers will be = 0 - 2
= 0 + (-2)
Here opposite of 2 has been added to 0.
That means subtraction of two integers is to add the opposite of the integer being subtracted.
Option (3) will be the answer.

Show that if x is any real number, there is a sequence of rational numbers converging to x.
Answer:
It has been proven from the explanation.
Step-by-step explanation:
If we assume that the real number x is greater than 0. Now, If on the contrary, a is less than 0, we can make the argument that;
Let us make n to be a natural number and m = m(n) to be the largest positive integer in such a way that;
m/n < x
Thus, (m+1)/n ≥ x and finally;
|x - m/n| < 1/n
If r_n = m/n. It will be easy to show from the definition of limits that the sequence (r_n) has limit x.
From earlier where we assumed that x > 0, the numbers that will be obtained by truncating the decimal expansion of "x" at the n-th place will be rational, and clearly have the limit "x". Although it implies we are now assuming every real number will have a decimal expansion.
Computer keyboard failures can be attributed to electrical defects or mechanical defects. A repair facility currently has 25 failed keyboards, 6 of which have electrical defects and 19 of which have mechanical defects. a. How many ways are there to randomly select 5 of these key boards for a thorough inspection
Answer:
Number of ways selection 5 key = 53,130
Step-by-step explanation:
Given:
Number of failed keyboard = 25
Number of electrical defects = 5
Number of mechanical defects = 19
Find:
Number of ways selection 5 key
Computation:
nCr
₂₅C₅
⇒ 25! / [5!(25! - 5!)]
⇒ 25! / [5!(20!)]
⇒ 53,130
Number of ways selection 5 key = 53,130

There are n applicants for the director of computing. The applicants are interviewed independently by each member of the three-person search committee and ranked from 1 to n. A candidate will be hired if he or she is ranked first by at least two of the three interviewers. Find the probability that a candidate will be accepted if the members of the committee really have no ability at all to judge the candidates and just rank the candidates randomly. In particular, compare this probability for the case of three candidates and the case of ten candidates.
Answer:
for n = 3
[tex]Z(3) = 0.26[/tex]
for n = 10
[tex]Z(3) = 0.028[/tex]
Step-by-step explanation:
from the question we are that
The number of applicant is n
The number of people on the committee is [tex]N = 3[/tex]
Generally given that the applicant ranking is random the probability of a candidate being accepted is mathematically represented as
[tex]Z(n) = N * \frac{1}{n} * \frac{1}{n} * \frac{n-1}{n} + \frac{1}{n} * \frac{1}{n} * \frac{1}{n}[/tex]
Now for n = 3
[tex]Z(3) = 3 * \frac{1}{3} * \frac{1}{3} * \frac{3-1}{3} + \frac{1}{3} * \frac{1}{3} * \frac{1}{3}[/tex]
[tex]Z(3) = 0.26[/tex]
Now for n = 10
[tex]Z(3) = 3 * \frac{1}{10} * \frac{1}{10} * \frac{10-1}{10} + \frac{1}{10} * \frac{1}{10} * \frac{1}{10}[/tex]
[tex]Z(3) = 0.028[/tex]

2 4/7 divided by 1 3/6=
Answer:
1.714
u can round it lol i just put it in a calculator
Answer: 1 and 5/7
Step-by-step explanation: To divide mixed numbers,
first write the mixed numbers as improper fractions.
So here, we can write 2 and 4/7 as the improper fraction 18/7
and we can write 1 and 3/6 as the improper fraction 9/6.
If you need a review of how to write a mixed number
as i improper fraction, let me know below and I will help.
So here, we have 18/7 ÷ 9/6.
Remember that dividing by a fraction is the same
as multiplying by the reciprocal of that fraction.
So here, 18/7 ÷ 9/6 is the same as 18/7 × 6/9.
So now we're simply multiplying fractions.
Remember that when we're multiplying fractions,
we want to cross-cancel first whenever possible.
So here, notice that we can cross-cancel 9 and 18 to 2 and 1.
However, we can't cross-cancel 7 and 6.
So we simply multiply across the numerators
and then across the denominators and we have 12/7.
We can write 12/7 as the mixed number 1 and 5/7.
