The length of the ladder nearest hundredth of a foot is 23 feet.

We have given that,

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 20 feet up.

The ladder makes an angle of [tex]77^{\circ}[/tex]  the ground.

[tex]sin(\theta)=\frac{perpendicular \ side}{hypotenous}[/tex]

Therefore we get,

[tex]\implies\frac{22}{H} =sin(77)[/tex]

[tex]\implies H=22/sin(77)[/tex]

[tex]\implies 22.59ft\\\\=23ft[/tex]

Therefore, The length of the ladder nearest hundredth of a foot is 23 feet.

In any triangle, a side is longer than the difference between the other two.  A side is also less the the sum of the other two. If these two rules are not obeyed then a triangle cannot be formed by those sides.

a = 7 cm.   b = 3 cm.

    Then   c > 7-3 = 4 cm         and  also,   c < 7+3 = 10 cm.

                  4 cm < the third side < 10 cm

Answer:

okay

Step-by-step explanation:

calculate the areas of those rectangles separately

Commision is the percentage on a cost of good. The amount of commision you owe your broker is  $133.51

Commision is the percentage on a cost of good. GIven the following parameters

Cost of good = $2,617.75

If your broker charges a commission of 5.1% of the cost, the amount charged is given as:

Amount charged = 5.1% of $2,617.75
Amount charged = 0.051 * $2,617.75
Amount charged =  $133.51

I took the quiz on

Step-by-step explanation:

Using proportions, considering the cost of the taxi per mile, it is found that Gary traveled 9.375 miles, not including the first.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the company charges 2.95 for the first mile and $0.3 per each 1/8 mile next = $2.4 per mile. After the first mile, he was charged a total of $25.45 - $2.95 = $22.5. Hence the number of miles is given by:

22.5/2.4 = 9.375.

Answer:

other leg = 16 cm

Step-by-step explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the other leg , then

x² + 12² = 20²

x² + 144 = 400 ( subtract 144 from both sides )

x² = 256 ( take square root of both sides )

x = [tex]\sqrt{256}[/tex] = 16

  B.  least 2°; greatest 178°

Step-by-step explanation:

The measure of ∠ADC will be the sum of the measures of the two acute angles ADB and BDC.

__

Each acute angle with a measure that is a whole number of degrees will have a measure between 1° and 89°, inclusive.

The least sum of two such angles will be ...

  1° +1° = 2°

The greatest sum of two such angles will be ...

  89° +89° = 178°

Answer:

x>-2

Step-by-step explanation:

First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)

Answer:

area = 232.5

perimeter=71.243

Answer:

The first thing that we need to do is subtract 4.5 from both sides because that would removed the 4.5 from the left side and leave us with m by itself.  So we get the following [tex]m=5.5[/tex] and that is our solution.

Hope this helps!  Let me know if you have any questions

Answer:

5.5

Step-by-step explanation:

to find additional value, subtract the known

[because 4.5 plus (+) a number (m) is equal to (=) 10, the number (m) must be equal to (=) 4.5 minus (-) 10.]

10 - 4.5 = 5.5

to find if this is correct, add it back

4.5 + 5.5 = 10

m = 5.5

The length of the diagonal of the garden with 19.6 square feet and 4.3 length is : 6.3 feet

A rectangle is a quadrilateral with four sides and four vertices  each of angle 90°.

Analysis:

Area of rectangle: 19.6 square feet

length of one side = 4.3 feet

width of one side = Area/length = 19.6/4.3 = 4.6 feet

the diagonal and width and length of a rectangle for a right angle triangle.

To find the diagonal, we use Pythagoras theorem

[tex](diagonal)^{2}[/tex] = [tex](length)^{2}[/tex] + [tex](width)^{2}[/tex]

[tex](diagonal)^{2}[/tex] = [tex](4.3)^{2}[/tex] + [tex](4.6)^{2}[/tex]

[tex](diagonal)^{2}[/tex] = 39.7

diagonal = [tex]\sqrt{39.7}[/tex] = 6.3 feet

in conclusion, the diagonal of the rectangular garden is 6.3 feet

The function h(x) =  6x² - 60x + 147 is a quadratic function, and the axis of symmetry of the function is x = 5

The equation of the function is given as:

h(x) =  6x² - 60x + 147

Differentiate the function

h'(x) = 12x - 60

Set the function to 0

12x - 60 = 0

Add 60 to both sides

12x = 60

Divide both sides by 12

x = 5

Hence, the axis of symmetry of the function is x = 5

The length of the curve  r=√(1+cos 2θ) is 2π after integrating over the limit 0 to π√2

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

We have:

[tex]\rm r=\sqrt{(1 +cos 2 \theta)}[/tex]

[tex]\rm r=\sqrt{2cos^2 \dfrac{2 \theta}{2}[/tex]

[tex]\rm r = \sqrt{2}cos\theta[/tex]

[tex]\rm \dfrac{dr}{d\theta}= -\sqrt{2}sin\theta[/tex]

Length:

[tex]\rm L = \int\limits^{\pi\sqrt2}_0 {\sqrt{r^2+(\dfrac{dr}{d\theta}})^2} \, d\theta[/tex]

After the value of r and dr/dθ and solve the definite integral, we will get:

L = 2π

Thus, the length of the curve  r=√(1+cos 2θ) is 2π after integrating over the limit 0 to π√2

The correct answer ofr this question is option D

Answer:

The measure of angle s is 22°

Step-by-step explanation:

Given:

To find:

∠1 and 158° are both on a straight line and supplementary.

(Supplementary angles are those angles that sum up to 180 degrees. )

So solving,

⇒ ∠1=180°-158°=22°         ....> Angles ∠1 and S are interior angles

Due to lines A and B being parallel, all interior lines are equal.

As a result, the answer is therefore 22°.

The distance between the two planes 4x-5y+z=16 and 8x-10y+2z=2 will be 2.34 units.

What is a plane?

A plane is a flat surface on which a straight line joining any two points on it would wholly lie.

Given equations are

[tex]4x-5y+z=16[/tex]

[tex]8x-10y+2z=2[/tex]

The distance between two planes is given by the formula:

[tex]D=\dfrac{|d_2-d_1|}{\sqrt{a^2+b^2+c^2}}[/tex]

Here from equations  

[tex]4x-5y+z=16[/tex]

[tex]8x-10y+2z=2[/tex]

We can also write the equation  [tex]8x-10y+2z=2[/tex]  as:

[tex]4x-5y+z=1[/tex]

So now the two equations are:

[tex]4x-5y+z=16[/tex]

[tex]4x-5y+z=1[/tex]

here a=4  b=-5  c =1 and d1=16  d2=1

Putting the values in the equation.

[tex]D=\dfrac{|-16+1|}{\sqrt{4^2+(-5)^2+(10^2)}}[/tex]

[tex]D=2.34[/tex]

Hence the distance between the two planes 4x-5y+z=16 and 8x-10y+2z=2 will be 2.34 units.
