Answer:

AB = 40 units

Step-by-step explanation:

Given:

AC = 6 x - 2

AB = 2 x + 12

BC = 3 x

Find:

AB

Computation:

Assume, AC is a straight line

So,

AC = AB + BC

6 x - 2 = 2 x + 12 + 3 x

6 x - 5 x = 14

x = 14

AB = 2 x + 12

AB = 2 (14) + 12

AB = 40 units

Answer:

Domain: [tex](-\infty,\infty)[/tex]

Range: [tex][-5,\infty)[/tex]

C

Step-by-step explanation:

Please refer to the graph.

Recall that the domain is the span of x-values covered by the graph, while the range is the span of y-values covered by the graph.

So we have the equation.

[tex]y=(x+3)^2-5[/tex]

This is a quadratic.

The domain of a quadratic is all real numbers. If you look at the graph, we can also see that the x-values will go on infinitely in both direction.

In interval notation, this is:

[tex](-\infty,\infty)[/tex]

For the range, note that the lowest the parabola goes is y=-5.

Therefore, our range is all values greater than or equal to -5.

In interval notation, this is:

[tex][-5,\infty)[/tex]

Note that we use brackets for the -5 because it is included in our range.

So, our answer is C

Answer:

Step-by-step explanation:

the domain and range of  y = (x+3)^2 - 5

Doman: (-∞,∞). {x|x∈R}

Range:{-5,∞),{y|y≥-5}

the solution is C

Answer:

-2p+1

Step-by-step explanation:

-4p+2p+(-2)+3

-2p+1

The equivalent expression of the expression {-4p+(-2)+2p+3}−4p+(−2)+2p+3 is -4p+2.

An expression is a combination of numbers, variables, function, indeterminants, symbols like addition, multiplication, subtraction and division. It is not usually present in equal to form.

We have been given one expression {-4p+(-2)+2p+3}−4p+(−2)+2p+3 and we have to find the equivalent expression by solving the expression.

First we need to put appropriate signs by solving brackets and the expression will look like after opening brackets and after opening of brackets the signs may change:

=-4p-2+2p+3-4p-2+2p+3

=-4p+2p-4p+2p-2+3-2+3

=-4p+2

Hence the equivalent expression of {-4p+(-2)+2p+3}−4p+(−2)+2p+3 is -4p+2.

Answer:

y= 5.99(g) + 6.49(u)

Step-by-step explanation:

1) First you determine the variable in the equation $5.99, $6.49, g, and u.

2) Then analyze the equation and identify that each gold baseball trophy (g) is worth $5.99, and each uniform baseball trophy (u) is worth $6.49 each.

3) Since you are finding the total you insert a plus sign.

The expression that could represent the total cost of all of the trophies will be C = 5.99g + 6.49u

Cost of gold baseball trophies = $5.99

Cost of uniform baseball trophies = $6.49

Number of gold baseball trophies ordered = g

Number of uniform baseball trophies ordered = u

Therefore, the total cost will be:

= (5.99 × g) + (6.49 × u)

C = 5.99g + 6.49u

Therefore, the expression that could represent the total cost of all of the trophies is C = 5.99g + 6.49u

Answer:

The minimum width of the placemat is 10 inches.

Step-by-step explanation:

Let suppose that placemat has a square form, whose width must be at least equal to the diameter of the pizza, so that pizza does not touch the table. Hence, the following relationship is obtained:

[tex]w = D[/tex]

Where:

[tex]w[/tex] - Width of the placemat, measured in inches.

[tex]D[/tex] - Diameter of pizza, measured in inches.

The area of the pizza, measured in square inches, is determined by this formula:

[tex]A = \frac{\pi}{4} \cdot D^{2}[/tex]

The diameter is cleared afterwards:

[tex]D = \sqrt{\frac{4\cdot A}{\pi} }[/tex]

If [tex]A = 78.5\,in^{2}[/tex] and [tex]\pi = 3.14[/tex], then:

[tex]D = \sqrt{\frac{4\cdot (78.5\,in^{2})}{3.14} }[/tex]

[tex]D = 10\,in[/tex]

The minimum width of the placemat is 10 inches.

The minimum width of a placemat that can be placed underneath the pizza so that the pizza wouldn't touch the table is; 10 inches

We are told that the pizza has an area of 78.5 in². Thus;

A = 78.5 in²

Now, the pizza is circular in shape and the minimum width of a placemat that can be placed underneath the pizza so that the pizza wouldn't touch the table will be the diameter of the pizza

Thus, area of a circle with diameter d is;

A = πd²/4

Plugging in the relevant values, we have;

78.5 = 3.14d²/4

d² = 78.5 × 4/3.14

d² = 100

d = √100

d = 10 inches.

Answer:

Step-by-step explanation:

For two events A and B to be independent, it means they can occur at the same time i.e the occurrence of one does not affect the other occurring. It is represented as P(A∩B) = P(A)P(B)

Given P( A) = 0.60 and P( A| B) = 0.60, to find P(B), we will use the formula for the conditional probability P( A| B) = P(A∩B) /P(B)

P( A| B) = P(A)P(B) /P(B)

P( A| B) = P(A)

Since  P( A| B) = 0.60, therefore P(A) is also equal to 0.60 and P(B) cannot be determined since they cancelled out already

12x + 32 = 12x - 7

12x - 12x + 32 = 12x - 12x - 7

32 = -7

This is a false statement so the answer is A) 0.

Additionally, you can see that we have the quantity 12x on both sides but on one side, it's being added by 32 and on the other, it's being subtracted by 7. How can a quantity added by 32 be equal to the same quantity subtracted by 7? It is impossible for a real number to do so, therefore, the answer is 0.

Answer:

Hey there!

Original Equation: 12x+32=12x-7

Subtract 12x: 32=-7

32 does not equal -7, so there is no solution.

Answer:

C/r

Step-by-step explanation:

The ratio of the circle's circumference to its radius is 2π

Please find attached a diagram of a circle and its radius

A circle is a two dimensional figure bounded by one curved line. All the straight lines that are drawn from a certain point within it to the bounding line, are equal.

The radius of a circle is the distance from the center of a circle to its circumference.

The radius of a circle is represented by r

The circumference of a circle is the perimeter of a circle. It is the distance round a circle.

The formula for the circumference of a circle is 2πr

π = pi = 22/7

r = radius

A ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

The ratio of a circle's circumference to its radius is

2πr : r

Divide both sides of the equation by r

= 2π : 1

= 2π

Answer:

Step-by-step explanation:

The confidence interval boundaries is represented mathematically as shown below;

CI = p±E where;

p is the percentage of people surveyed

E is the margin of error

Given parameters

p = 40% = 0.4

E = 3.1% = 0.031

Required

Confidence interval corresponds to the given information.

Substituting the given parameters into the given formula:

CI = p±E

CI = 0.4±0.031

CI = (0.4-0.031, 0.4+0.031)

CI = (0.369, 0.431)

Hence the confidence interval that corresponds with the information is 0.369≤[tex]\mu[/tex]≤0.431.

Answer:

i) 3/4

ii) 1/3

iii) 1/3

iv) 5/6 cents

Step-by-step explanation:

Any ratio can be written as a fraction.

For example 3:4 can be writen as 3/4 or 14:42 as 14/42.

After you convert them to fractions you then simplify them by finding their highest common factor (HCF) and then divide both numerator and denominator by the HCF. When you cant simplify the fraction anymore, that is the fraction in its lowest terms.

Answer: 4

Step-by-step explanation:

Let the consecutive integers be x, x+1 and x+2.

There are three consecutive integers such that twice the sum of the smallest and the largest is eight more than twice the largest. This means that:

2(x + x+2) = 2(x+2) + 8

2(2x + 2) = 2x + 4 + 8

4x + 4 = 2x + 12

Collect like terms

4x - 2x = 12 - 4

2x = 8

x = 8/2

x = 4

The smallest integer in the sequence is 4

Step-by-step explanation:

When two letters are right next to each other, you multiply them. Since a and b are next to each other, we multiply them together.

[tex]A=\frac{5}{12}[/tex]

[tex]B=\frac{1}{3}[/tex]

To multiply fractions, you place them next to each other and multiply across.

[tex]\frac{5}{12}*\frac{1}{3} \\5*1=5\\12*3=36[/tex]

Answer:

2029

Step-by-step explanation:

We can write an equation:

0.28+0.006x=0.51

A few things explained:

The constant 0.28 comes from the fact in 1990, 28% of babies were born to parents who were not married. 28%=0.28

0.006 represents 0.6% and x represents the number of years will pass until 49% of babies will be born out of wedlock

0.51 represents 51%. 51% represents the percentage of babies who will be born to parents not married (100% - 49%=51%). You want to use 51% instead of 49% because the right side represents the babies born to parents not married.

We can solve the equation:

0.28+0.006x=0.51

0.006x=0.23

x=38.33

Since you can't have 38.3333 years, we'll say that 39 will pass until 49% of babies are born out of wedlock.

So, we add 39 years to 1990.

1990+39=2029
