Plz help!!!

A summer camp counselor wants to
calculate a length, x, in feet, across a pond
as represented in the sketch. Segments AC
and DE intersect at B, and AEB and CDB
have the same measure. What is the distance
across the pond? Round to the nearest
hundredth.

Answer:

(x - 3)² = -9

Solution:

Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.

Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.

Answer:

x=3+3i, 3-3i

Step-by-step explanation:

-4(x-3)²+7=43

(x-3)(x-3)= x²-6x+9

-4(x²-6x+9)+7=43

-4x²+24x-36+7=43

-4x²+24x-29=43

-4x²+24x-72=0

-x²+6x-18=0

Quadratic formula: -b+√(b²-4ac)  / 2a

-(-6)+√((-6)²-4(1)(18))   /  2(1)

6+√(36-72)   /2

6+√(-36)   / 2

x=6+6i   / 2

x=3+3i, 3-3i

Answer:

x=-4

Step-by-step explanation:

5+4x=-11

4x=-11-5

4x=-16

x=-16/4

x=-4

5+4(-4)=-11

5-16=-11

-11=-11

Answer:

x = -4

Step-by-step explanation:

5 + 4x =  -11

4x = -11 - 5

4x = -16 (Divide 4 both sides)

x = -4

5 + 4x =  -11

5 + 4(-4) = -11

5 - 16 = -11

-11 = -11

Answer:

It is 6 inches long

Step-by-step explanation:

Since they are similar the ratio of width and length will be the same for both so the ratio for the first one is 2/3 so whats two thirds of 9? 6, and that's your answer. If you have any questions about this just leave a comment

Answer:

162°

Step-by-step explanation:

To convert from radian to degree measure

degree measure = radian measure × [tex]\frac{180}{\pi }[/tex] , then

degree = [tex]\frac{9\pi }{10}[/tex] × [tex]\frac{180}{\pi }[/tex] ( cancel π and 10/ 180 to simplify )

            = 9 × 18

           = 162°

Answer:

324.

Step-by-step explanation:

===================================================

Explanation:

See the diagram below. It shows there are 10 sides, so n = 10.

We'll plug this value of n into the formula below to find the sum of all ten interior angles

S = sum of interior angles

S = 180(n-2)

S = 180(10-2)

S = 180(8)

S = 1440 degrees

---------------

A different approach:

Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.

We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.

Each interior angle adjacent to this 36 degree exterior angle is

180-E = 180-36 = 144 degrees

Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees

Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.

Answer:

[tex]y = 2[/tex]

Step-by-step explanation:

1) Divide both sides by 2.

[tex]3y - 6 = 0[/tex]

2) Add 6 to both sides.

[tex]3y = 6[/tex]

3) Divide both sides by 3.

[tex]y = \frac{6}{3} [/tex]

4) Simplify 6/3 to 2.

[tex]y = 2[/tex]

Therefor, the answer is y = 2.

Answer:

Let's find the slope between your two points.

(4,2);(3,0)

Answer:

m=2

Answer:

Step-by-step explanation:

B = 22 × 3 × 52?—or is it supposed to be

B = 2² × 3 × 5² ?

A = 2² × 3 × 5

B = 2² × 3 × 5²

GCF = 2² × 3 × 5 = 60

A = 2² × 3 × 5

B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13

GCF = 2² × 3 × 5 = 60

Answer:

rectangle

Step-by-step explanation:

They want the most specific term. A rectangle is a parallelogram and quadrilateral, but not all parallelograms and quadrilaterals are rectangles.

Answer:

630 is the LCM

Step-by-step explanation:

Prime factorization of the numbers:

30 = 2 × 3 × 5

90 = 2 × 3 × 3 × 5

315 = 3 × 3 × 5 × 7

LCM(30, 90, 315)

= 2 × 3 × 3 × 5 × 7

= 630

hope this helps :)

Answer:

A. (-4,4)

B. (0,0)

C. (-5,-2)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The term added which completes the square is half of the linear coefficient squared. In a quadratic ax^2+bx+c, b is the linear coefficient, so in this case the added term would be

(13/2)^2=169/4=42.25

The term 13/2 is added to complete the square.

A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.

For the given situation,

The quadratic equation is x^2 + 13x -3 = 0.

This is not the perfect square term. So we can solve this by using the completing the square method.

⇒ [tex]x^{2} +13x-3=0[/tex]

⇒ [tex]x^{2} +13x=3[/tex]

⇒ [tex]x^{2} +13x + (\frac{13}{2})^{2} =3+(\frac{13}{2})^{2}[/tex]

⇒ [tex](x+\frac{13}{2} )^{2} =3+\frac{169}{4}[/tex]

⇒ [tex](x+\frac{13}{2} )^{2} =\frac{181}{4}[/tex]

⇒ [tex]\sqrt{ (x+\frac{13}{2} )}^{2} =\sqrt{\frac{181}{4}}[/tex]

⇒ [tex](x+\frac{13}{2})[/tex] = ± [tex]\frac{\sqrt{181} }{2}[/tex]

Hence  we can conclude that the term 13/2 is added to complete the square.

Answer:

Scale factor = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]

                    = [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]

                    = [tex]\frac{7}{35}[/tex]

                    = [tex]\frac{1}{5}[/tex]

Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]
