Now, consider a right triangle with legs of lengths 5 cm and 12 cm. what is the length c of the hypotenuse of this triangle? express your answer to t

Answers

Answer 1
Final answer:

The length of the hypotenuse of a right triangle with legs of 5 cm and 12 cm is 13 cm.

Explanation:

The length of the hypotenuse of a right triangle can be found by using the Pythagorean theorem. The theorem states that the square of the hypotenuse is equal to the sum of the squares of the two legs.

In this case, we have a right triangle with legs of 5 cm and 12 cm. To find the length of the hypotenuse, we can use the formula c = √(a² + b²).

Substituting the given values, we get c = √(5² + 12²) = √(25 + 144) = √169 = 13 cm.

Time sensitive question. Find the sum of the first 26 terms of an arithmetic series whose first term is 7 and 26th term is 93.

Answers

ANSWER

[tex]S_{26}=1300[/tex]

EXPLANATION

The sum of an arithmetic sequence whose first term and last terms are known is calculated using

[tex]S_{n}= \frac{n}{2} (a + l)[/tex]

From the given information, the first term of the series is

[tex]a = 7[/tex]

and the last term of the series is

[tex]l = 93[/tex]

The sum of the first 26 terms is

[tex]S_{26}= \frac{26}{2} (7 + 93)[/tex]

[tex]S_{26}= 13 (100)[/tex]

[tex]S_{26}=1300[/tex]

Final answer:

The sum of the first 26 terms of the given arithmetic series is 1300, obtained using the sum formula S = n/2 * (a1 + an) for arithmetic series.

Explanation:

To find the sum of the first 26 terms of an arithmetic series whose first term (a1) is 7 and the 26th term (a26) is 93, you can use the formula for the sum of an arithmetic series: S = n/2*(a1 + an). Here, n is the number of terms, a1 is the first term, and an is the nth term. In this case, we have n = 26, a1 = 7, and a26 = 93.

The sum, S, of the series is calculated as follows:
S = 26/2 * (7 + 93) = 13 * (100) = 1300.

Therefore, the sum of the first 26 terms of the arithmetic series is 1300.

Answers

$50 per day x 6 days = 300

20% = 0.2, times t = 0.2t

The equation would be: f(t) = 300 + 0.2t

Answer:

Option D:[tex]f(t)=300+0.2 t[/tex]

Step-by-step explanation:

We are given that Mikayla is a waitress

She makes a guaranteed per day =$50

Her tips per day =20 % of weekly tips t

We have to find a function that represents the amount of money makes by Mikayla in one week

[tex]20% of t=\frac{20}{100}t=0.2t[/tex]

She works per week=6 days

She earns in 6 days=[tex]50\times 6[/tex]=$300

Total earning of Mikayla in one week =[tex]300+0.2t[/tex]

[tex]f(t)=300+0.2 t[/tex]

Hence, option D is true.

Could you Help me there was 395 Lenin ice cups at thesnack shop. People bought 177 lemon ice cups . How many lemon ice cups are still all the snack shop.

Answers

Answer:

There are 288 cups left

Step-by-step explanation:

Take the amount that were there (395) and subtract the amount that were sold (177).  that is the amount that are left

395-177 = 218

There are 288 cups left

after selling 177 cups, there are 218 lemon ice cups still at the snack shop.

To calculate how many lemon ice cups are still at the snack shop after some were sold, we need to perform a simple subtraction operation. The initial quantity of lemon ice cups was 395. After selling 177 cups, we subtract 177 from 395 to find out how many are left.

Here's the calculation:

Start with the initial number of lemon ice cups: 395.Subtract the number of lemon ice cups sold: 395 - 177.Calculate the remaining number of lemon ice cups: 218.

So, after selling 177 cups, there are 218 lemon ice cups still at the snack shop.

The circumcenter of a triangel is the point equidistant from the vertices of the triangel. True or false

Answers

Answer:

True

Step-by-step explanation:

The circumcenter is the center of the circumscribing circle, the circle that intersects each of the vertices. Since the points on a circle are equidistant from its center, the vertices of a triangle are equidistant from the circumcenter.

Final answer:

The circumcenter of a triangle is the point that is equidistant from the vertices of the triangle.

Explanation:

True

The circumcenter of a triangle is the point that is equidistant from the vertices of the triangle. This means that the distance from the circumcenter to each vertex of the triangle is the same.

For example, in an equilateral triangle, the circumcenter is the point where all the perpendicular bisectors of the sides intersect.

9. A gear of radius 6.1 cm turns at 11 revolutions per second. What is the linear velocity of the gear in meters per second?

Show your work

Answers

Answer:

4.22 meters per second.

Step-by-step explanation:

First multiply the revs per second by pi:

= 11pi = 34.558.

Now multiply this by the diameter which is 2*6.1 = 12.2 cm = 0.122 m.

Linear velocity =  0.122 * 34.558

= 4.22 m/s.

Linear velocity of the gear in meters per second is  4.22 m/s.

What is linear velocity?

Linear velocity is the measure of “the rate of change of displacement with respect to time when the object moves along a straight path.” It is a vector quantity.

Given

Gear of radius = 6.1 cm

Gear of diameter = [tex]2 \times 6.1 = 12.2 cm[/tex] = 0.122 m

Revolutions per second = [tex]11\pi[/tex] = 34.558

Linear velocity of the gear  =  diameter × Revolutions per second

Linear velocity = 0.122 × 34.558

= 4.22 m/s

Linear velocity of the gear in meters per second is  4.22 m/s.

A square and a rhombus have the following in common EXCEPT:

A. Opposite pairs of sides are parallel

B. Opposite pairs of sides are congruent

C. Pairs of interior and exterior angles are supplementary

D. All interior angles are 90 degree

Answers

D.All interior angles are 90 degrees

Let's analyze each choice to determine which one is the exception, that is, a property that is not shared between a square and a rhombus:
A. Opposite pairs of sides are parallel:
This is true for both a square and a rhombus. By definition, both a square and a rhombus have opposite sides that are parallel.
B. Opposite pairs of sides are congruent:
This property also holds true for both squares and rhombi. In a square, all four sides are equal in length. In a rhombus, opposite sides are equal in length.
C. Pairs of interior and exterior angles are supplementary:
Again, this is a common feature of both squares and rhombuses. In any parallelogram (which includes both squares and rhombuses), each pair of interior and exterior angles on the same side are supplementary, totaling 180 degrees.
D. All interior angles are 90 degrees:
This is where we can find the exception. In a square, all four interior angles are indeed 90 degrees. However, this is not the case for a rhombus. A rhombus does not necessarily have right angles; its angles can be of any measure as long as opposite angles are equal and the sum of the angles is 360 degrees, which is true for any quadrilateral.
Therefore, the correct answer to the question is:
D. All interior angles are 90 degrees
This is the property that is not common between a square and a rhombus, making it the exception.

Formula please and solve

Answers

Answer:

The sum of the first 499 terms is 249001

Step-by-step explanation:

* Lets revise the arithmetic sequence

- There is a constant difference between each two consecutive

  numbers

- Ex:

# 2  ,  5  ,  8  ,  11  ,  ……………………….

# 5  ,  10  ,  15  ,  20  ,  …………………………

# 12  ,  10  ,  8  ,  6  ,  ……………………………

* General term (nth term) of an Arithmetic sequence:

- U1 = a  ,  U2  = a + d  ,  U3  = a + 2d  ,  U4 = a + 3d  ,  U5 = a + 4d

- Un = a + (n – 1)d, where a is the first term , d is the difference

 between each two consecutive terms n is the position of the

 number

- The sum of first n terms of an Arithmetic sequence is calculate from

 Sn = n/2[a + l], where a is the first term and l is the last term

* Now lets solve the problem

∵ The terms of the sequence are 1 , 3 , 5 , 7 , ......... , 997

∵ The first term is 1 and the second term is 3

∴ The common difference d = 3 - 1 = 2

∵ The first term is 1

∵ The last term is 997

∵ The common difference is 2

- Lets find how many terms in the sequence

∵ an = a + (n - 1) d

∴ 997 = 1 + (n - 1) 2 ⇒ subtract 1 from both sides

∴ 996 = (n - 1) 2 ⇒ divide both sides by 2

∴ 498 = n - 1 ⇒ add 1 for both sides

∴ n = 499

∴ The sequence has 499 terms

- Lets find the sum of the first 499 terms  

∵ Sn = n/2[a + l]

∵ n = 499 , a = 1 , l = 997

∴ S499 = 499/2[1 + 997] = 499/2 × 998 = 249001

* The sum of the first 499 terms is 249001

Final answer:

The sum of the series 1+3+5+7+...+997 is calculated using Gauss's approach for arithmetic series, resulting in a sum of 249500.

Explanation:

To find the sum of the series 1+3+5+7+...+997 using Gauss's approach, we first recognize that this is an arithmetic series where each term increases by a constant difference, in this case, 2. The first term, a, is 1 and the last term, l, is 997. We can find the number of terms, n, in the series using the formula: n = (l - a) / common difference + 1, which in this case is (997 - 1) / 2 + 1 = 499. Then, the sum of an arithmetic series can be found using the formula: Sum = n/2 * (a + l), so the sum of this series is 499/2 * (1 + 997) = 249500.

Express this number in standard form.

Renee is creating a rectangular garden in her backyard. The length of the garden is 8 feet. The perimeter of the garden must be at least 30 feet and no more than 32 feet. Use a compound inequality to find the range of values for the width w of the garden.

Answers

Answer:

The appropriate compound inequality is then 14 ft ≤ W ≤ 16 ft

Step-by-step explanation:

30 ft perimeter:  P = 30 ft = 2L + 2W = 2(8 ft) + 2W

Solving for W, we get:  30 ft - 16 ft = 14 ft.  The minimum width, W, is 14 ft.

32 ft perimeter:  

P = 32 ft = 2L + 2W = 2(8 ft) + 2W

Solving for W, we get:  32 ft - 16 ft = 16 ft.  The minimum width, W, is 16 ft.

The appropriate compound inequality is then 14 ft ≤ W ≤ 16 ft

Answer:

Range of width = [7,8]

Step-by-step explanation:

Let w be the width of garden,

The length of garden, l = 8 feet

We have perimeter = 2 x ( length + width)

Perimeter = 2 x ( 8 + w)

The perimeter of the garden must be at least 30 feet and no more than 32 feet.

That is

             30 ≤ 2 x ( 8 + w) ≤ 32

             15 ≤ 8 + w ≤ 16

              7 ≤ w ≤ 8

So range of width = [7,8]

Answers

Answer:

Step-by-step explanation:

This is a third degree polynomial because we are given three roots to multiply together to get it.  Even though we only see "2 + i" the conjugate rule tells us that 2 - i MUST also be a root.  Thus, the 3 roots are x = -4, x = 2 + i, x = 2 - i.

Setting those up as factors looks like this (keep in mind that the standard form for the imaginary unit in factor form is ALWAYS "x -"):

If x = -4, then the factor is (x + 4)

If x = 2 + i, then the factor is (x - (2 + i)) which simplifies to (x - 2 - i)

If x = 2 - i, then the factor is (x - (2 - i)) which simplifies to (x - 2 + i)

Now we can FOIL all three of those together, starting with the 2 imaginary factors first (it's just easier that way!):

(x - 2 - i)(x - 2 + i) = [tex]x^2-2x+ix-2x+4-2i-ix+2i-i^2[/tex]

Combining like terms and canceling out the things that cancel out leaves us with:

[tex]x^2-4x+4-i^2[/tex]

Remembr that [tex]i^2=-1[/tex], so we can rewrite that as

[tex]x^2-4x+4-(-1)[/tex] and

[tex]x^2-4x+4+1=x^2-4x+5[/tex]

That's the product of the 2 imaginary factors.  Now we need to FOIL in the real factor:

[tex](x+4)(x^2-4x+5)[/tex]

That product is

[tex]x^3-4x^2+5x+4x^2-16x+20[/tex]

which simplifies down to
