Answer:

SAS Similarity Theorem

Step-by-step explanation:

we know that

SAS Similarity Theorem: States that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar

In this problem

∠HJZ=∠RJW ----> by vertical angles

and

WJ/HJ=JR/JZ

substitute the values

8/4=6/3

2=2 ----> is true

so

Two sides of triangle HJZ are proportional with the two corresponding sides of triangle WJR and the included angle is congruent

therefore

Triangles are similar by SAS Similarity Theorem

[2 1 | 1 0 ] • x = [5 | 10]

We multiply by the inverse of

[2 1 | 1 0 ]

det( [2 1 | 1 0] ) = -1

=> [2 1 | 1 0 ]^(-1) = (-1)•[0 -1 | -1 2 ] =

= [0 1 | 1 -2]

=> [2 1 | 1 0 ] • x = [5 | 10]

=> x = [2 1 | 1 0 ]^(-1) • [5 | 10]

=> x = [0 1 | 1 -2] • [5 | 10]

=> x = [0+10 | 5-20]

=> x = [10 | -15]

ANSWER

[tex]a_n= \frac{1}{2}( {2}^{n - 1} )[/tex]

EXPLANATION

The corresponding ordered pairs from the graph are:

(2,1) (3,2) (4,4) (5,8)

The y-values are:

1,2,4,8

The first term term is the term before 1,this has to be.

[tex]a_1= \frac{1}{2} [/tex]

The common ratio is

[tex]r = \frac{2}{1} = 2[/tex]

The nth term is given by

[tex]a_n=a_1 {(r}^{n - 1} )[/tex]

Let's substitute the values to get,

[tex]a_n= \frac{1}{2} \times {(2}^{n - 1} )[/tex]

This simplifies to,

[tex]a_n= \frac{1}{2} {(2}^{n - 1} )[/tex]

The graph represents a geometric sequence with a common ratio of 2, best defined by the function an = 2(2)^n – 1.

This graph represents a geometric sequence. A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the 'common ratio'. In this case, the common ratio is 2, because each y-coordinate is twice the y-coordinate of the point before it (2, 1), (3, 2), (4, 4), (5, 8). Therefore, the sequence is best represented by the option A an = 2(2)^n – 1.

5 unit to left, 3 units down is the correct answer.

Answer:

9 ft

Step-by-step explanation:

The ladder is 15 foot

The height the ladder reaches from the bottom of the wall is 12 ft

The distance (x) from the bottom of the wall to the foot of the ladder is:

Applying the Pythagorean theorem;

x = [tex]\sqrt{15^2 - 12^2}[/tex] = 9 ft

A 15 foot ladder needs to be placed at a distance of 9 foot from the base of the house so that it exactly reaches the top of a 12 foot wall.

In this case;

Therefore;

We are going to find the distance of the ladder from the base of the house on the ground which is the other leg.

Using Pythagoras theorem;

[tex]a^{2} + b^{2} = c^{2}[/tex]

Taking the horizontal distance of the ladder from the wall as b

Then;

[tex]b^{2} = c^{2} -a^{2}[/tex]

therefore,

[tex]b^{2} = 15^{2} -12^{2}[/tex]

[tex]b^{2} = 225 -144[/tex]

[tex]b^{2} = 81[/tex]

[tex]b = \sqrt{81} \\b= 9 ft[/tex]

Hence; the ladder needs to be placed at a distance of 9 foot from the base of the house.

Answer:

D. 40%

Step-by-step explanation:

You can fill in the table completely

[tex]\begin{array}{cccc}&\text{Hamburgers}&\text{Pizza}&\text{Total}\\\text{Adults}&0.24&0.36&0.6\\\text{Children}&0.11&0.29&0.4\\\text{Total}&0.35&0.65&1\end{array}[/tex]

From this table you can state that the probability that a randomly selected person is a child is 0.4 that is 40%.

The percentage of the people surveyed are children is:

                               40%

We are given a table as follows:

                            HAMBURGERS               PIZZA             TOTAL

ADULTS                   0.24                              0.36                0.6

CHILDREN                0.11                               0.29                 0.4

TOTAL                      0.35                              0.65                   1

Now we are asked to find the percent of students that were surveyed.

From the table we may see that the probability of children who were surveyed are:

     0.11+0.29=0.40

( since, the second column gives the total of the probability of children)

Hence, in percentage form it is given by:

0.40×100=40%

          Hence, the answer is:

               40%

Answer:

It ends at 7:30.

Final answer:

Tim's swimming practice starts at 7 o'clock and after adding the 30 minutes duration, it ends at 7:30.

Explanation:

The question pertains to adding time, specifically calculating the end time of an activity based on its duration. If Tim's swimming practice starts at 7 o'clock and ends 30 minutes later, the end time can be found by adding 30 minutes to the start time.

Here's how you calculate it:

Start with the initial time of the practice, which is 7:00.

Add the duration of the practice, which is 30 minutes.

Since there are 60 minutes in an hour, adding 30 minutes to 7:00 does not increase the hour value. Therefore, the practice ends at 7:30.

So, Tim's swimming practice ends at 7:30.

To analyze whether two algebraic expressions are equivalent, you can use an interactive tool such as an algebra solver or calculator to compare the results of the expressions for various values of x. Simplify the expressions if possible, compare the simplified expressions, and verify the results by substituting different x-values.

To determine if the expressions 7x – 4 and 6x – 4 – x are equivalent, you can use an interactive tool like an online algebra solver or calculator. This process usually involves comparing the results of the expressions for multiple values of x.

Step 1:

Firstly, simplify the expressions if possible. For the second expression, 6x – 4 – x, you can simplify it as 5x – 4.

Step 2:

Now, compare the simplified expressions, you can see that 7x - 4 and 5x - 4 are not equivalent as the coefficients of x (7 and 5) are not equal.

Step 3:

Last, for verification, you can substitute different values of x into both equations and see if the outputs are the same. If the outputs are different then, the equations are not equivalent.

Answer:

The ratio of x:y is 1/2

Step-by-step explanation:

Let

x----> the number of Kg of brand A

y ---> the number of Kg of brand B

we know that

400x+280y=320(x+y)

400x+280y=320x+320y

400x-320x=320y-280y

80x=40y

x/y=40/80

x/y=1/2

Final answer:

The ratio of Brand A coffee to Brand B coffee (x to y) required to achieve a mixture cost of $320/kg is 1 : 2. This is derived using the weighted average cost formula and simplifying the resulting equation.

Explanation:

To find the ratio of x to y for the mix of Brand A and Brand B coffee beans, we can use a weighted average cost formula since the mixture's cost is given to be $320/kg. Let's assume we have x kilograms of Brand A coffee at $400/kg and y kilograms of Brand B coffee at $280/kg. The total cost for all the coffee is then $400x + $280y.

The combined weight of the coffee is x + y kilograms, and for the mixture to cost $320/kg, the total cost divided by the total weight must equal $320. Therefore, we can set up the following equation:

($400x + $280y) / (x + y) = $320

Multiplying both sides by (x + y) we get:

$400x + $280y = $320x + $320y

Now, we subtract $320y from both sides to isolate terms with x:

$400x - $320x = $320y - $280y

$80x = $40y

Dividing both sides by $40 gives us the simplified ratio:

x : y = 1 : 2

Thus, the ratio of Brand A coffee to Brand B coffee in the mixture to get a $320/kg cost is 1 : 2.

ANSWER

36√3 square units.

EXPLANATION

The area of a parallelogram is obtained by multiplying the base by the height.

We use the sine ratio to obtain the height.

[tex] \sin(60 \degree) = \frac{h}{6} [/tex]

[tex]h = 6 \sin(60 \degree) [/tex]

[tex]h = 3 \sqrt{3} [/tex]

The area becomes:

[tex]12 \times 3 \sqrt{3} = 36 \sqrt{3} {units}^{2} [/tex]

1) domain of the first is ( R ) because of its root(3) and its range is (R) because of its root again

2)and domain of the last , is [0,+infinity)

and for its range , you can draw it such as picture and will be [0,- infinity)

Answer:

1. [tex]Dom(f)=\mathbb{R} [/tex], [tex]Ran(f)=\mathbb{R} [/tex].

2. [tex]Dom(f)=\{x\in \mathbb{R} : x\geq 0 \} [/tex], [tex]Ran(f)=\{x\in \mathbb{R} : x \leq 0 \}  [/tex].

Step-by-step explanation:

1. Since the degree of the radical is an odd number, the radicand can be any real number, then [tex] x [/tex] can take any real value, so the domain of [tex] f [/tex] is the set of all real numbers, [tex] \mathbb{R} [/tex].

Now, if [tex] x\in \mathbb{R} [/tex] , then [tex] x-3 \in \mathbb{R}  [/tex], so  [tex] \sqrt[3]{x-3} \in \mathbb{R}  [/tex], and thus [tex] f(x)\in \mathbb{R} [/tex], which leads us to affirm that the range of  [tex] f [/tex]  is the set of all real numbers, [tex] \mathbb{R} [/tex].

2. Since the degree of the radical is an even number, the radicand can not be a negative number, then [tex] x [/tex] can take only nonnegaive values, so the domain of [tex] f [/tex] is the set of all nonnegative numbers, [tex] \{x\in \mathbb{R} : x\geq 0 \}  [/tex].

Now, if [tex] x\geq 0 [/tex] , then [tex]  \sqrt{x}\geq 0  [/tex] so  [tex]  -3\sqrt{x}\leq 0  [/tex], and thus [tex] f(x)\in \mathbb{R} [/tex], which leads us to affirm that the range of  [tex] f [/tex]  is the set of all nonpositive numbers, [tex] \{x\in \mathbb{R} : x \leq 0 \} [/tex].

Check the picture below.

let's notice that 89/36 =>  2 and 17/36, namely 2π or two revolutions and then a bit more, the 17/36 slack, so then -89π/36 = - 2π - 17π/36.

the positive angle will of course be 2π - 17π/36 = 55π/36.

Since supplementary angles add up to 180°, you would subtracted the measurement that you have from 180°.

Ex.

180-x= y

X being the measurement that you have, and y being the missing measurement.

Answer:

$47, 17.5%

Step-by-step explanation:

When she buys the $20 book, she can get 40% off either the $15, $12, or $10 book.  She'll save the most by getting 40% off the $15 book.

Then, when she buys the $12 book, she'll get %40 off the $10 book.

The total she pays is:

20 + (0.60)(15) + 12 + (0.60)(10)

20 + 9 + 12 + 6

47

Without the discounts, the cost of the books would have been:

20 + 15 + 12 + 10

57

So she saves $10.  10 out of 57 is approximately 17.5%.

For this case we have by definition, that the area of a square base pyramid is given by:

[tex]V = \frac {L ^ 2 * h} {3}[/tex]

Where:

L: It's the side of the square base

h: It's the height of the pyramid

We have that[tex]L = 15 \ units[/tex], then [tex]L ^ 2 = 15 ^ 2 = 225 \ units ^ 2[/tex]

Substituting:

[tex]V = \frac {225 * 8} {3}\\V = 600 \ units ^ 3[/tex]

Finally, the volume of the pyramid is [tex]600 \ units ^ 3[/tex]

Answer:

[tex]600 \ units ^ 3[/tex]

Answer:

D.

Step-by-step explanation:

For this case we have:

Let k> 0:

To graph [tex]y = f (x) + k,[/tex] the graph k units is moved up.

To graph [tex]y = f (x) -k[/tex], the graph moves k units down.

Let h> 0:

To graph[tex]y = f (x-h)[/tex], the graph moves h units to the right.

To graph [tex]y = f (x + h),[/tex] the graph moves h units to the left.

So, we have:

[tex]y = f (x) = - \sqrt [3] {x}[/tex]

Shifted 7 units up and 4 to the right means:

[tex]k = 1\\h = 4[/tex]

[tex]y = f (x) = - \sqrt [3] {x-4} +7[/tex]
