Answer:

4 and 5.

Step-by-step explanation:

4x^2 + 9x + 5 = 0

To solve this equation you need 2 numbers whose product is 20 and who add up to to +9.

These are 4 and 5.

(There are no 2 whole numbers whose product is 20 and sum is 5.)

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia
OleMash [197]

Answer:

Diameter of tank = 19.5 ft

Step-by-step explanation:

Volume of cylinder = Base area x Height.

Base area = Area of circle

\texttt{ Area of circle}=\frac{\pi d^2}{4}

Height = 20 ft.

Volume of tank = 6000 cubic feet .

\texttt{ Volume of cylinder = Base area x Height.}\\\\6000=\frac{\pi d^2}{4}\times 20\\\\d^2=381.97\\\\d=19.5ft

Diameter of tank = 19.5 ft

Which is an equation of the line with slope 2 that passes through (3, 1)? Ay-1 = 2(x-3) By + 1 = 2(x + 3) Cy-3 = 2(x - 1) Dy- 3
Flura [38]

Answer:

A

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 2 and (a, b) = (3, 1 ), thus

y - 1 = 2(x - 3) → A
