Answer:

  A.  25.6 ft

  B.  28.2 ft

Step-by-step explanation:

The triangle inequality tells you the length of any side of a triangle lies between the sum and difference of the lengths of the other two sides:

  43.7 -30.7 < ? < 43.7 +30.7

  13.0 < ? < 74.4

Only two answer choices fall within that range:

  25.6 ft, 28.2 ft

Do this equation have one solution, many solution, or no solution?

Answers

9514 1404 393

Answer:

  1 solution

Step-by-step explanation:

The coefficients of x are different on each side of the equal sign, so this equation has one solution.

_____

Additional comment

If the x-coefficients are the same on each side of the equal sign, then you need to look at the constants. If they are the same, there are an infinite number of solutions; if they are different, no solutions.

This equation simplifies to ...

  3x -3 = 2x +9

  x = 12 . . . . . . . . add 3-2x to both sides

The solution of expression by applying distributive property and combining like terms,

⇒ x = 12

Given that,

The mathematical expression is,

⇒ 3(x - 1) = 2x + 9

Now, simplify the expression by applying distributive property and combining like terms,

⇒ 3(x - 1) = 2x + 9

Apply distributive property,

⇒ 3x - 3 = 2x + 9

Combine like terms,

⇒ 3x - 2x = 9 + 3

Therefore, the solution of expression is,

⇒ x = 12

A parabola has focus (5,7) and directrix y=0(the X-axis). Write an equation that says point (x,y) is on the
parabola.

Answers

Answer:

Step-by-step explanation:

focus of the parabola is (2,0) and directrix is x=-2. Here,a=2.So, Equation becomes, y2=4∗2x⇒y2=8x, which is the required equation of parabola.

The equation of a parabola with the given focus and directrix is x²-10x+74=14y.

What is an equation of a parabola?

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line

Given that, a parabola has focus (5,7) and directrix y=0.

When the focus (h, k) of a parabola and the equation of the directrix y = c are given, the equation of the parabola is given by (x-h)²+k²-c²=2(k-c)y

Here, y=c=0

Now, (x-5)²+7²-0²=2(7-0)y

x²-10x+25+49=14y

x²-10x+74=14y

Therefore, the equation of a parabola is x²-10x+74=14y.

10 friends decided to buy a joint gift for their best friend. But as it happens, the two gave up and decided to buy her a present themselves. Thus, the remaining 8 friends had to add 50 dollars each to buy the gift.
How much did the gift cost?

Answers

Answer:

The answer is $2000

Step-by-step explanation:

8 had to give an extra $50 each.

8 x 50 = 400

400 ÷ 2 ( the two that changed their mind) = 200

Each person was to give $200

10 × 200 = 2000

Solve system of equations

3x+6y=18
X+3y=15

Answers

Answer:

x = - 12, y = 9

Step-by-step explanation:

Given the 2 equations

3x + 6y = 18 → (1)

x + 3y = 15 → (2)

Multiplying (2) by - 3 and adding to (1) eliminates the term in x

- 3x - 9y = - 45 → (3)

Add (1) and (3) term by term to eliminate x

- 3y = - 27 ( divide both sides by - 3 )

y = 9

Substitute y = 9 into either of the 2 equations and evaluate for x

Substituting into (2)

x + 3(9) = 15

x + 27 = 15 ( subtract 27 from both sides )

x = - 12

Solution is (- 12, 9 )

B)y = -60.4x2+ 348.1x - 334.2
C)y = 0.001x2+ 35.672
D)y = -60.4x2 - 334.2

Answers

The table is an illustration of a quadratic regression model

The function that best models the data is y = -60.4x^2 +348.1x -334.2

How to determine the function that models the data?

To determine the function that models the data, we make use of a graphing calculator.

Using the graphing calculator, we have the following calculation summary

a = -60.4

b = 348.1

c = -334.2

A quadratic regression model is represented as:

y = ax^2 + bx + c

So, we have:

y = -60.4x^2 +348.1x -334.2

Hence, the function that best models the data is y = -60.4x^2 +348.1x -334.2

Step-by-step explanation: This is the correct answer on Edge 2021, just took the quiz and made a 100%. Hope this helps ^-^.

The value of 'x' is 108° . Option C

How to determine the value of x

From the illustration,

Angle RQS is at Q = x degrees

Angles KLM is at L = x - 36 degrees

Note that they are corresponding angles

Corresponding angles sum up to 180°

Then equate both angles to 180 degrees

x + x - 36 = 180°

Collect like terms

2x = 180 + 36

2x = 216

Make 'x' subject of formula

x = 216 / 2

x = 108°

Therefore, the value of 'x' is 108° . Option C
