Find the surface area
Brut [27]

Answer:

Step-by-step explanation:

area of top=7×6=42 yd²

area of bottom=3×6=18 yd²

area of two rectangles=2[4×6]=48 yd²

area of two trapezoids=2[1/2(7+3)×3.5]=35 yd²

total surface area=42+18+48+35=143 yd²

Complete the equation of the line through (-9 -9) and (-6 0)
Katena32 [7]

Answer:

y = 3x + 18

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 9, - 9) and (x₂, y₂ ) = (- 6, 0)

m = \frac{0+9}{-6+9} = \frac{9}{3} = 3, thus

y = 3x + c ← is the partial equation of the line

To find c substitute either of the 2 points into the partial equation

Using (- 6, 0), then

0 = - 18 + c ⇒ c = 0 + 18 = 18

y = 3x + 18 ← equation of line

The stream of water from a fountain follows a parabolic path. The stream reaches a maximum height of 12 feet, represented by a v
tia_tia [17]

Answer:

y=-3/16(x-8)^2+12

Step-by-step explanation:

Refer to the vertex form equation for a parabola:

y=a(x-h)^2+k where (h,k) is the vertex.

Therefore, we have y=a(x-8)^2+12 as our equation so far. If we plug in (16,0) we can find a:

0=a(16-8)^2+12

0=64a+12

-12=64a

-12/64=a

-3/16=a

Therefore, your final equation is y=-3/16(x-8)^2+12
