Answer:

The height of building is 21 m

Step-by-step explanation:

According to the Pythagorus Theorem

(Hypotenuse)² = (Base)² + (Perpendicular)²

We need to find out the perpendiclar so arranging the equation

(Hypotenuse)² - (Base)² =  (Perpendicular)²

Putting the values

(36)² - (29)² = (Perpendicular)²

1296 - 841 = (Perpendicular)²

455 = (Perpendicular)²

Taking Square root on both sides

√455 = √(Perpendicular)²

21.33 = Perpendicular

Rounding off the value is 21 m

Answer:

In short: 29 rounded to the nearest ten is 30.

Step-by-step explanation:

Locate  the tens place (2) then look at the digit to the right (9): In this case, the digit to the right (9) is 5 or above. So, we add 1 to the tens place (2).The digit(s) after the (2) are replaced by zeros (or dropped). Thus, we get 30 as the answer.

Answer:

Option 2. That is the best option for this problem

Answer:

A. (x,y)-(-x,y)

Step-by-step explanation:

1. Look at the first FG, It is Positive X and Positive Y

2. A reflection is simply flipping something to the opposite side, So now look at which part the 2nd FG is.

3. Now as we notice the G is in the Negative X, So that would be -X, But then when we look at the Y, It is in the positives!

Answer:

x = 23 and y = 15

Let one number be x and another be y

The sum of two numbers is 38

x + y = 38

x = 38 - y

The greater number is 8 more than the other number.

x - y = 8

x = 8 + y

solve both equations:

8 + y = 38 - y

y + y = 38 - 8

2y = 30

y = 15

solve for x:

x = 8 + y

x = 8 + 15

x = 23

Let one number be x and another be y

The sum of two numbers is 38

x + y = 38

x = 38 - y

The greater number is 8 more than the other number.

x - y = 8

x = 8 + y

solve both equations:

8 + y = 38 - y

y + y = 38 - 8

2y = 30

[tex]{{\bold{{{{{ \green{y = 15}}}}}}}}[/tex]

solve for x:

x = 8 + y

x = 8 + 15

Answer:

It should be 71

Step-by-step explanation:

every triangles equals to 180

so 180 - 38 - 71 = 71

Answer:

32units

Step-by-step Explanation :

Area of rectangle = length × Width

x = 8 × 4

x = 32

Given, 

• Length = 8 units

• Width= 4 units

Formula :-

★ Area of Rectangle = Length × Width

Now, Solve :

Area = 8 x 4 = > 32 square units

★ Hence, Area of Rectangle is 32 units.

Answer:

24

Step-by-step explanation:

The resulting solid will be a cylinder with a base radius of 14 cm and a height of 24cm. Then the correct option is D.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

The perimeter of the rectangle shown is 76 cm.

It is rotated about line b. A rectangle with a perimeter of 76 centimeters is shown.

The rectangle is rotated about line b at a side with a length of 24 centimeters.

Another side (x) of the rectangle will be

[tex]76 = 2 (24+x)[/tex]

then x is 14 cm

Then the resulting solid will be a cylinder of a base radius of 14 cm and height of 24cm. Then the correct option is D.

Answer:

[tex]x=3.099566703 \textsf{ (9 dp)}[/tex]

Step-by-step explanation:

Newton-Rhapson method

This iterative method finds roots of equations in the form f(x) = 0 when an equation cannot be solved using the usual analytical methods

This method works by finding the tangent to a function at a point [tex]x_0[/tex], and using its x-intercept for the next iteration, [tex]x_1[/tex].  Repeating the process iteratively gets you closer to the root.

Newton-Rhapson formula

[tex]x_{n+1}=x_n-\dfrac{f(x_n)}{f'(x_n)}[/tex]

Given function:

[tex]f(x)=4x^3-15x^2+10x-6=0[/tex]

First check that the function is in the form f(x) = 0 ← yes!

(if it is not, rearrange it so that it is equal to zero)

Now differentiate the function:

[tex]f'(x)=12x^2-30x+10[/tex]

Substitute the function and its derivative into the N-R formula:

[tex]x_{n+1}=x_n-\dfrac{4{x_n}^3-15{x_n}^2+10{x_n}-6}{12{x_n}^2-30{x_n}+10}[/tex]

To determine which value to set as [tex]x_0[/tex] examine the function.

[tex]f(x)=4x^3-15x^2+10x-6[/tex] is a cubic function with a positive leading coefficient.

Therefore, its endpoint behavior is:

[tex]f(x) \rightarrow \infty \textsf{ as } x \rightarrow \infty\\f(x) \rightarrow -\infty \textsf{ as } x \rightarrow -\infty[/tex]

Its y-intercept is (0, -6)

It's turning points are when [tex]f'(x)=0[/tex]

Therefore, using the quadratic formula, its turning points are:

[tex]x=\dfrac{-(-30)\pm\sqrt{(-30)^2-4(12)(10)}}{2(12)}=\dfrac{15\pm\sqrt{105}}{12}[/tex]

Sketching the graph (see attached) suggests that the x-intercept will be when:

[tex]x > \dfrac{15+\sqrt{105}}{12}[/tex]

[tex]\implies x > 2.1039...[/tex]

Let's start with inputting values of x = 3 and x = 4 into the function:

[tex]f(3)=4(3)^3-15(3)^2+10(3)-6=-3\\f(4)=4(4)^3-15(4)^2+10(4)-6=50[/tex]

The x-intercept will be between values where there is a change in sign.  As there is a change in sign between f(3) and f(4), the root is [tex]3 < x < 4[/tex]

Therefore, let [tex]x_0=3[/tex]

[tex]\implies x_{1}=x_0-\dfrac{4{x_0}^3-15{x_0}^2+10{x_0}-6}{12{x_0}^2-30{x_0}+10}[/tex]

[tex]\implies x_{1}=3-\dfrac{4(3)^3-15(3)^2+10(3)-6}{12(3)^2-30(3)+10}=\dfrac{87}{28}[/tex]

[tex]\implies x_{2}=x_1-\dfrac{4{x_1}^3-15{x_1}^2+10{x_1}-6}{12{x_1}^2-30{x_1}+10}=3.099605842...[/tex]

[tex]\implies x_{3}=x_2-\dfrac{4{x_2}^3-15{x_2}^2+10{x_2}-6}{12{x_2}^2-30{x_2}+10}=3.099566704...[/tex]

[tex]\implies x_{4}=x_3-\dfrac{4{x_3}^3-15{x_3}^2+10{x_3}-6}{12{x_3}^2-30{x_3}+10}=3.099566703...[/tex]

[tex]\implies x_{5}=x_4-\dfrac{4{x_4}^3-15{x_4}^2+10{x_4}-6}{12{x_4}^2-30{x_4}+10}=3.099566703...[/tex]

Therefore, [tex]x=3.099566703 \textsf{ (9 dp)}[/tex]

The total minimum credit card payment of Jimmy's credit card bill which he wants to pay as New Year's resolution is $449.24.

Interest is the amount charged on the principal amount with a fixed rate of interest for a time period.

As a New Year's resolution, Jimmy has agreed to pay off his 4 credit cards and completely eliminate his credit card debt within the next 12 months.

The balances and annual percentage rates for Jimmy's credit cards is,

Credit Card Current Balance        APR

A $563. 00 16%                            a. $321. 83

B $2,525. 00 21%                         b. $361. 45

C $972. 00 19%                            c. $374. 65

D $389. 00 17%                            d. $411. 25.

The monthly payment for credit car A is,

[tex]P_m=\dfrac{563}{{[1-(1+\dfrac{0.16}{12})]}^{\dfrac{-12}{0.16/12}}}\\P_m=51.08[/tex]

The total monthly payment is,

[tex]P_t=51.08\times12\\P_t=612.96[/tex]

Now, the charge of interest is,

[tex]I=612.96-563\\I=49.96[/tex]

Similarly, for credit card B is interset charge is $296.32 and for C is $102.96.

Thus, the total interest charge is,

[tex]I=46.96+296.32+102.96\\I=449.24[/tex]

Thus, the total minimum credit card payment of Jimmy's credit card bill which he wants to pay as New Year's resolution is $449.24.

Step-by-step explanation:

So let's start with what we know!

Gift certificate = $100

T-shirts = $15 each

Dress shirts = $22 each

You need to buy at least one dress shirt in the process and at least spend $90

You can simply find the combinations by going in desmos and writing in:

15x + 22y <= 100

y > 1

15x + 22y >= 90

Find the combinations by looking at the integer values of x, and using only the integer values of y ( do not round them, just cut them down to the integer). Look where all the regions are shaded

The possible combinations are as follows

Note: I am going to initial t-shirts to T and dress shirts to D

x ≥ 0

y ≥ (1/2)x

y ≤ 4 - x

Step-by-step explanation:

Solid lines: ≤ and ≥

Dashed lines:  < and >

You need to create linear equations for the diagonal lines.

Shaded areas are ≥ if it is shaded above the line, and ≤ if shaded below the line.

Inequalities:

vertical line:   x ≥ 0

The Z-score of an employee making an annual salary of $28000 is -1.5.

It is given that,

Mean μ = $34000

Standard deviation σ = $4000

Salary x = $28000

Z-score is a numerical measurement that describes a value's relationship to the mean of values.

Formula to calculate z-score = (x - μ)/σ

So, z-score = (28000-34000)/4000z = -1.5

Therefore, the z-score of an employee making an annual salary of $28000 is -1.5.
