What is the value of c such that t^2+(10/3)t+c is a perfect-square trinomial?
Answers
The value of c such that the expression is a perfect-square trinomial is 25/9.
What is perfect square?A perfect square is a positive integer that is generated by multiplying an integer by itself. Perfect squares can be summed up as numbers that are the products of integers multiplied by themselves. Perfect squares are numbers that can be formed by squaring an integer or a whole number.
The given expression is t² + (10/3)t + c.
The identity of perfect square is given as:
(a+b)² = a² + 2ab + b²
Rewrite the given expression as:
t² + (10/3)t + c = (t + (5/3))² + (c - 25/9)
To make this a perfect-square trinomial, we need (c - 25/9) to be equal to zero, thus:
c = 25/9
Hence, the value of c such that the expression is a perfect-square trinomial is 25/9.

in the u.s government a memeber if the senate serves for 4 years longer than a member of the House of Representatives. If a member of the House of Representatives serves for h years, write an expression for how many years a member of the senate serves .
Answers
A member of the senate will serve for (h+4) years.
An expression, in mathematics, is a finite set of combinations and/ or numbers and variables that accurately represents the the context in question. When two or more expressions are connected using the equality sign then an equation is formed.
Here, we are given that in the US government a member of the senate serves for 4 years longer than a member of the House of Representatives.
Also the House of Representatives serves for- h years
Thus, the number of years a member of the Senate will serve will be 4 more than the number h
= h + 4
Thus, a member of the senate serves for (h+4) years.

13. Find the smallest number which when divided by 21,28,36 and 44 leaves a
remainder of 3 in each case?
Answers
Answer:
2775
Step-by-step explanation:
Well of course since the problem is not restricted, the smallest number is 3. I'm almost sure that's not what you mean. The next smallest number is 2775. I found that using a programing language. I'm sure as well that does not satisfy the question, either.
I think you are intended to do this by finding the lowest common multiple and adding 3.
21: 3 * 7
28: 2 * 2 * 7
36: 2 * 2 * 3 * 3
44: 2 * 2 * 11
LCM = 2 * 2 * 3 * 3 * 7 * 11 = 2772
Now add 3 and the number you want is 2775

Are:
x = 7.6x = 0.4How to solve the quadratic equation?Here we want to solve the quadratic equation:
x^2 - 8x = -3
First we can move all the terms to the left side so we get:
x^2 - 8x + 3 = 0
Using the quadratic formula (or Bhaskara's formula) we can get the solutions for x as:
\(x = \frac{8 \pm \sqrt{(-8)^2 - 4*¨1*3} }{2*1} \\\\x = \frac{8 \pm 7.2 }{2}\)
Then the two solutions for the quadratic equation are:
x = (8 + 7.2)/2 = 7.6
x = (8 - 7.2)/2 =0.4

How to find the expected winning ?The possible values of the net winning would be the amount you win at net if you win first prize, second prize, or nothing.
The possible values would therefore be:
$54,999, $14,999, and -$1.
These show that if you win the first or second prize, you will deduct the $ 1 you bet. And if you win nothing, you would have lost $ 1.
The expected winnings would be:

Answers
ANSWER
\(\frac{2}{52}\)EXPLANATION
In a pack of 52 cards, there are four suits: two black suits and two red suits.
Each suit of cards contains one king. This implies that there are 2 kings of black cards.
Therefore, the probability that the drawn card is a king of black is the number of kings of black cards divided by the total number of cards.
That is:
\(P=\frac{2}{52}\)That is the answer.
