Answer:

Step-by-step explanation:

2,401 = 7^6 - 2x

2401 + 2x =  117649

           2x = 117649 - 2401

          2x = 115248

x = 115248 / 2

x = 57624

Hokiris ladder has two legs that are each 8 feet long. When the ladder is opened safely and locked for use, the legs are 4 feet
guajiro [1.7K]

To solve this problem you must apply the proccedure shown below:

1- The ladder forms an isosceles triangle, because it has two equal sides.

2- Let's call the angle \alpha. To calculate it , you can divide the triangle into two equal right triangles and the angle \alpha will be divided into two equal parts too. Therefore, you can calculate the half of the angle and then multiply it by two, as following:

Sin^{-1}(\alpha 1)=opposite/hypotenuse

Sin^{-1}(\alpha1)=8/2\\  \alpha1=14.47 degrees

\alpha =2\alpha 1\\ 2=2(14.47degrees)\\ \alpha =28.95degrees

The answer is: 28.95degrees

What is the center of the equation (x+12)^2 + (y-9)^2= 35
Reil [10]

Answer:

(-12,9)

Step-by-step explanation:

The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point on the graph.

Therefore, in the equation (x+12)^2 + (y-9)^2 = 35, the center point on the graph would be (-12,9).

Find the area of a triangle with legs that are 9mm 6mm and 12mm
Sidana [21]

Here we are given the three sides of the triangle.

So we have Heron's formula to find its area.

Heron's formula is given by :

A= \sqrt{S(S-A)(S-B)(S-C)}

where A, B and C are sides of triangle and S is semi perimeter which is given by,

S= \frac{A+B+C}{2}

plugging values of A, B and C to find S

S= \frac{9+6+12}{2}

S=13.5

Now plugging values of A, B , C and S in Heron's formula

A= \sqrt{13.5(13.5-9)(13.5-6)(13.5-12)}

A=26.14 mm²

Answer: Area of triangle is 26.14 mm².

What is the vertex and axis of symmetry for y=4x^2-12x+9?
VLD [36.1K]

Answer:

axis of symmetry   x=3/2

vertex  (3/2, 0)

Step-by-step explanation:

to find the axis of symmetry we use h = -b/2a

where ax^2 + bx+c


h = -(-12)/2(4)

h= 12/8

h = 3/2

the axis of symmetry is x = 3/2

the x coordinate of the vertex is h x=3/2

to find k, the y coordinate of the vertex, substitute x=3/2 into the equation

y=4x^2-12x+9

y=4(3/2) ^2-12(3/2)+9

 = 4 (9/4)  - 6*3 +9

  = 9-18+9

  = 0


the vertex (3/2, 0)
