F(x)=(x+1)(x-3)(x-4)

Mathematics
1 answer:
denis23 [38]2 years ago
5 0

Answer:

x=-1, x=3, x=4

Step-by-step explanation:

1. Substitute 0 for f(x)

0=(x+1)(x-3)(x-4)

2. Set each set of parenthesis equal to 0

0=x+1, 0=x-3, 0=x-4

3. Solve for x

x=-1, x=3, x=4

<u>Answer:</u>

<h2><em>$18.5</em></h2>

<em></em>

<u>Step-by-step explanation:</u>

44-7=37  (we don't need the price of the planetarium ticket, so subtract 7)

37÷2=18.5   (since the entree fees are equal, divide 37 by 2)

A two-digit number is written at random. The probability that the number will be odd is . The probability that the number will b
Makovka662 [10]
Step-by-step explanation:
GIVEN: Two digit number means we will have to choose from numbers 0-9 for the second digit and 1-9 for the first digit. (since zero can't be in the tens place)
Formula: We will use m x n. That is, m is the number of elements we can use for the first digit and n will be the number of elements we can use for the second digit.
Sample Space: To get the probability, we must find the sample space or all the outcomes.
m - 9 elements (1-9)
m - 9 elements (1-9)n - 10 elements (0-9)
m x n = 9x10 =90
90 is our sample space.
A. An odd number
Conditions: For an odd number, the second number will determine whether or not it is an odd number. For the first digit, we can use 1-9.
Elements:
m - 9 elements (1-9)
m - 9 elements (1-9)n - 5 elements (1,3,5,7,9)
m x n=9x5=45
SOLVE (probability)
Probability= possible outcomes/sample space
P=45/90
P=1/2
B. Larger than 75.
Conditions: The first digit could be equal to 7 or greater. But n will only be greater than 5 if and only if m=7 and n could be any number if m>7.
Elements 1:
m - 1 element (7)
m - 1 element (7)n - 4 elements (6,7,8,9)
m - 1 element (7)n - 4 elements (6,7,8,9)m x n=1x4=4
Elements 2:
m - 2 elements (8,9)
m - 2 elements (8,9)n - 10 elements (0,1,2,3,4,5,6,7,8,9,)
m - 2 elements (8,9)n - 10 elements (0,1,2,3,4,5,6,7,8,9,)mxn=2x10=20
TOTAL: 4+20=24
SOLVE (PROBABILITY)
Probability= possible outcomes/sample space
P=24/90
P=4/15
C. multiple of 5
Condition: the second digit must be either 0 or 5 and the first digit could be any digit.
Elements:
m - 9 elements (1-9)
m - 9 elements (1-9)n - 2 elements (0,5)
m x n =9x2=18
SOLVE (PROBABILITY)
P=18/90
P=1/5
D. An even number smaller than 40
Condition: The first digit could be equal to 4 but the second digit must be even (excluding zero). Another situation is the first digit would be greater than 4 and the second digit would be any even number.
Elements 1:
m - 1 element (4)
n - 4 elements (2,4,6,8)
m x n = 1x4=4
Elements 2:
m - 5 elements (5,6,7,8,9)
n - 5 elements (0,2,4,6,8)
mxn=5x5=25
TOTAL: 25+4=29
SOLVE: Probability
P=29/90

What number must be added to the expression below to complete the square? x^2+x. a.1/4 b.1/2 c.2 d.1
torisob [31]

Option a. 1/4 is the right answer

Step-by-step explanation:

Given expression is:

x^2+x

Here

we know that

a = x

In order to find the number which should be added

comparing with the formula

(a+b)^2 = a^2+2ab+b^2

2ab = x\\2.x.b = x\\b=\frac{x}{2x}\\b = \frac{1}{2}

So, we will add the square of 1/2 which is 1/4

Hence,

Option a. 1/4 is the right answer
