Sean and mason run out of gas while fishing from their boat in the bay. They set off an emergency flare with and initial velocit

y of 30 meters per second. The height of the flare in meters can be modeled by h(t) = -5t^2 + 30t, where t represents the number of seconds after launch. Sean wants to know how high the flare will reach above the surface of water. a. Write the function in vertex form, factoring so the coefficient of t^2 is 1. b. Complete the square using the vertex form of the function. c. How high will the flare reach?

Which equation represents the line that passes through the point (1,5) with a slope of-2
svlad2 [7]

Answer:

The equation of the line would be y = -2x + 7

Step-by-step explanation:

In order to solve this, use the point and the slope in point-slope form. Then solve for y.

y - y1 = m(x - x1)

y - 5 = -2(x - 1)

y - 5 = -2x + 2

y = -2x + 7

The pyramid shown has a square base that is 14 centimeters on each side. The slant height is 15 centimeters. What is the surface
Ksenya-84 [330]
We know that

surface area=area of the base+4*[area of one lateral triangle side]

area of the base=b²
b is the side length of the square
b=14 cm
area of the base=14²-----> 196 cm²

area of one lateral triangle side=b*h/2
b is the side length of the square
b=14 cm
h is the height of the lateral triangle side
h is equal to the slant height 
h=15 cm

area of one lateral triangle side=14*15/2----> 105 cm²

surface area=196+4*[105]------> 616 cm²

the answer is
the surface area is 616 cm²

Area = 5/6 x 3/4

= (5x3) / (6x4)

= 15/24
