Answer:

The measure of angle JKM is 108°

Step-by-step explanation:

step 1

Find the value of x

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

∠M+∠L+∠MKL=180°

substitute the given values

4x+5x+6x=180°

15x=180°

x=12°

step 2

Find the measure of angle JKM

we know that

Angles MKL and JKM are supplementary angles

so

∠MKL+∠JKM=180°

6x+∠JKM=180°

substitute the value of x

6(12)+∠JKM=180°

∠JKM=180°-72°=108°

Answer:

108

Step-by-step explanation:

We know sum of all the 3 angles in a triangle is equal to 180. We can set up an equation for the triangle KML using the information given:

[tex]4x+5x+6x=180\\15x=180\\x=\frac{180}{15}=12[/tex]

So measure of Angle MKL is 6x, or 6(12) = 72

Now, we know Angle JKM + Angle MKL = 180 (straight line). Thus,

Angle JKM + 72 = 180

Angle JKM = 180 - 72 = 108

Step-by-step explanation:

The boxplot of the distribution 66, 62, 58, 52, 48, 46, 44, 34, 33, 31, 31, 30, 27, 25, 24, 21, and 19 is given below.

The correct option is B.

The given distribution is as follows: 66, 62, 58, 52, 48, 46, 44, 34, 33, 31, 31, 30, 27, 25, 24, 21, 19.

To create a boxplot, we need to identify the minimum, lower quartile (Q1), median (Q2), upper quartile (Q3), and maximum values.

Arranging the data in ascending order, we have: 19, 21, 24, 25, 27, 30, 31, 31, 33, 34, 44, 46, 48, 52, 58, 62, 66.

The minimum value is 19, the maximum value is 66, and the median (Q2) is the middle value of the sorted data, which is 33.

To find the quartiles, we need to locate the positions that divide the data into quarters. The lower quartile (Q1) is the median of the lower half of the data, and the upper quartile (Q3) is the median of the upper half.

Counting from the minimum, we find that Q1 is 27, and counting from the maximum, we find that Q3 is 48.

With this information, the box plot is given in the attached image below.

Therefore, the correct option is B.

Answer:

$2109

Step-by-step explanation:

We are given that Mr and Mrs Wilson payed a rent of $575 for the banquet hall and a per head of $13 for the catering dinner for their daughter's wedding.

We are to find the total amount they paid.

Amount paid for dinner for 118 people = [tex]118 \times 13[/tex] = $1534

Total amount payed by Mr and Mrs Wilson = $1534 + $575 = $2109

Inverse check:

2109 - 575 = 1534

1534/118 = 13

For this case we must find the domain of the following function:

[tex]y = ln (x + 2)[/tex]

By definition, the domain of a function is given by all the values for which the function is defined.

In this case, the argument of the expression must be greater than 0 to be defined.

[tex]x + 2> 0\\x> -2[/tex]

Thus, the domain of the function is given by all the values of x greater than -2.

Answer:

Domain: [tex]x> -2[/tex]

Answer:

1.5 hours is the correct answer !

Step-by-step explanation:

Speed is the rate of distance over time.

The equations are:

The given parameters are:

[tex]\mathbf{(t_1,d_1) = (1:30pm,35miles)}[/tex]

[tex]\mathbf{(t_2,d_2) = (4:30pm,230miles)}[/tex]

So, the time difference is:

[tex]\mathbf{t=4:30pm - 1:30pm}[/tex]

[tex]\mathbf{t=3\ hours}[/tex]

The distance traveled is:

[tex]\mathbf{d = 230miles - 35miles}[/tex]

[tex]\mathbf{d = 195miles}[/tex]

Speed is calculated as:

[tex]\mathbf{Speed = \frac{Distance}{Time}}[/tex]

So, we have:

[tex]\mathbf{Speed = \frac{195\ miles}{3\ hours}}[/tex]

Multiply both sides by 3 hours

[tex]\mathbf{3\ hours \times Speed = 195\ miles}[/tex]

Divide both sides by Speed

[tex]\mathbf{3\ hours = \frac{195\ miles}{Speed}}[/tex]

Hence, the equations are:

[tex]\mathbf{Speed = \frac{195\ miles}{3\ hours}}[/tex]

[tex]\mathbf{3\ hours \times Speed = 195\ miles}[/tex]

[tex]\mathbf{3\ hours = \frac{195\ miles}{Speed}}[/tex]

Answer:

(-∞, ∞).

Step-by-step explanation:

This function can have any real value.

Range = (-∞, ∞).

The range of f(x) = 3/4x – 4 is [tex]\( (-\infty, \infty) \)[/tex].

To find the range of the function [tex]\( f(x) = \frac{3}{4}x - 4 \)[/tex], we need to consider all possible output values of the function as x varies.

The function x is a linear function with a slope of [tex]\( \frac{3}{4} \)[/tex], which means it increases or decreases steadily as x increases or decreases, respectively. Since there are no restrictions on the domain of the function (i.e., x can take any real value), the range of the function is also unrestricted.

To find the range, we can examine the behavior of the function as x approaches positive infinity and negative infinity:

1. As x approaches positive infinity, [tex]\( f(x) \)[/tex] also approaches positive infinity.

2. As x approaches negative infinity, [tex]\( f(x) \)[/tex] also approaches negative infinity.

Therefore, the range of the function [tex]\( f(x) = \frac{3}{4}x - 4 \)[/tex] is all real numbers. In interval notation, we can represent the range as [tex]\( (-\infty, \infty) \)[/tex].

Answer:

The correct answer option is D. He multiplied the divisor by 100 and dividend by 10.

Step-by-step explanation:

We are given that Miguel completed the division where initially he had to divide 754 by 0.52.

To make it easier, he multiplied both the divisor and the dividend by the same number to get rid of the decimal in the divisor.

If he multiplied the divisor by 100, he should have multiplied the dividend by 100 too. But instead, he mistakenly multiplied the divisor by 100 and dividend by 10.

ANSWER

[tex] \log_{4}(3x + 4) = 2[/tex]

EXPLANATION

Consider the equation:

[tex] \log_{4}(3x + 4) = 2[/tex]

When we rewrite this logarithmic equation in the exponential form, we obtain:

[tex]3x + 4= {4}^{2} [/tex]

Note that to write a logarithmic equation in exponential form, the base of the logarithm is still the base in the exponential form.

We now simplify the RHS.

[tex]3x + 4 = 16[/tex]

Group like terms

[tex]3x = 16 - 4[/tex]

This implies that

[tex]3x = 12[/tex]

Divide both sides by 3

[tex] \frac{3x}{3} = \frac{12}{3} [/tex]

Simplify to get;

[tex]x = 4[/tex]

Hence the equation that has x=4 as a solution is

[tex] \log_{4}(3x + 4) = 2[/tex]

Another way to do this is to substitute x=4 into each equation. The equation that is satisfied is the correct choice.

Using the addition identity for sine

sin(x + y) = sinxcosy - cosxsiny

Consider the left side

cos²(45 - A) - sin²(45 - A)

cos²(45 - A) = 1 - sin²(45 - A), thus

1 - sin²(45 - A) - sin²(45 - A)

= 1 - 2sin²(45 - A) ← expand sin(45 - A)

= 1 - 2(sin45cosA - cos45sinA)²

= 1 - 2([tex]\frac{\sqrt{2} }{2}[/tex]cosA - [tex]\frac{\sqrt{2} }{2}[/tex]sinA)²

= 1 - 2([tex]\frac{1}{2}[/tex]cos²A - sinAcosA + [tex]\frac{1}{2}[/tex]sin²A)

= 1 - cos²A + 2sinAcosA - sin²A

= sin²A + 2sinAcosA - sin²A

= 2sinAcosA

= sin2A = right side ⇒ verified

By Using the addition identity for sine; sin(x + y) = sinx cosy - cosx siny.

It is proved that cos²(45 - A) - sin²(45 - A)= Sin2A.

We can use the fact that:

[tex]\sin(\theta ^\circ) = \cos(90 - \theta^\circ)[/tex]

To convert the sine to cosine (but the angles won't stay the same unless it's 45 degrees).

Using the addition identity for sine

sin(x + y) = sinx cosy - cosx siny

Now,

cos²(45 - A) - sin²(45 - A)

cos²(45 - A) = 1 - sin²(45 - A),

1 - sin²(45 - A) - sin²(45 - A)

= 1 - 2sin²(45 - A)  

Expand sin(45 - A)

= 1 - 2(sin45cosA - cos45sinA)²

= 1 - 2(√2/2 cosA - √2/2 sinA)²

= 1 - 2(1/2 cos²A - sinAcosA + 1/2 sin²A)

= 1 - cos²A + 2sinAcosA - sin²A

= sin²A + 2sinAcosA - sin²A

= 2sinAcosA

cos²(45 - A) - sin²(45 - A) = sin2A = right side

Hence, it is verified.

They're not equivalent.

[tex]|x|[/tex] (vertical bars) represents the absolute value of x. How it works is that it turns negative numbers positive but leaves 0 and positive numbers alone (hence it gets a number's distance from 0 on the number line).

[tex][x][/tex] (square brackets) usually represents the floor function, which returns the largest integer that is less than or equal to x. (The floor of x can also be written as [tex]\lfloor x \rfloor[/tex] --- it depends on what your textbook/source says).

To solve [tex]|x| - 3 = 7[/tex], you first transform it into the equivalent equation [tex]|x| = 10[/tex]. Then by definition of absolute value, there are only two solutions for the first equation: x = 10 or x = -10.

[x] = 10 has infinitely many solutions. For example, the floor of 10 is 10, so [tex][10] = 10[/tex], thus a solution for the second equation is x = 10

The floor of 10.1 is 10, so [tex][10.1] = 10[/tex], thus another solution for the second equation is x = 10.1.

The two equations do not have the same solution set (as x = 10.1 does not solve |x| - 3 = 7 but solves [x] = 10), so they're not equivalent.

Answer:

So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number. Proof: "The product of two rational numbers is rational."

Sum of two rational numbers is always a rational number is always true .

A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. For example, −3/7 is a rational number, as is every integer
