Solve for x in the equation 2x2-5x+1=3
Butoxors [25]
2x^2 - 5x + 1 = 3

Subtract 3 from both sides
2x^2 - 5x + 1  - 3 = 3  - 3

2x^2 - 5x - 2 = 0

Use quadratic formula with A = 2,  B =  - 5,   C =  - 2

x =  - b +- sqrt b^2 - 4ac/2a

x =  - ( - 5) +- sqrt (- 5)^2  - 4(2)( - 2)/(2)(2)

x =   5 +- sqrt 41/4

x =  5/4 + 1/4sqrt 41  or x = 5/4 + - 1/4 sqrt 41


Answer:  x = 5/4 + 1/4 sqrt 41
               x = 5/4 +  - 1/4 sqrt 41




Hope that helps!!!!! (D)

A triangular pyramid has lateral faces with bases of 8 meters and heights of 10
Vlada [557]

Answer:

147.7 m²

Step-by-step explanation:

Area of the triangular faces = 1/2 × base × height

A triangular pyramid has lateral faces with bases of 8 meters and heights of 10 meters.

Hence: 1/2 × 8 × 10 = 40 m²

A triangle has 3 faces, hence, area of the 3 faces = 3 × 40 m²

= 120m²

The area of the base of the pyramid is 27.7 square meters.

Hence, the surface area of the pyramid is calculated as:

Area of the 3 lateral faces of the pyramid + Base area

= 120m² + 27.7 m²

= 147.7 m²

The surface area of the pyramid is 147.7 square meters.
