5p-9=2p+12
5p-2p=12+9
3p=21
p=21/3
p=7

P=3
+9 on both sides cancels the 9 and makes it 7p=21 
7 divided by 21 is 3
p=3

A balloon is rising at a constant speed of 5 ftys. A boy is cycling along a straight road at a speed of 15 ftys. When he passes
Ket [755]

Answer:

  13 ft/s

Step-by-step explanation:

t seconds after the boy passes under the balloon the distance between them is ...

  d = √((15t)² +(45+5t)²) = √(250t² +450t +2025)

The rate of change of d with respect to t is ...

  dd/dt = (500t +450)/(2√(250t² +450t +2025)) = (50t +45)/√(10t² +18t +81)

At t=3, this derivative evaluates to ...

  dd/dt = (50·3 +45)/√(90+54+81) = 195/15 = 13

The distance between the boy and the balloon is increasing at the rate of 13 ft per second.

_____

The boy is moving horizontally at 15 ft/s, so his position relative to the spot under the balloon is 15t feet after t seconds.

The balloon starts at 45 feet above the boy and is moving upward at 5 ft/s, so its vertical distance from the spot under the balloon is 45+5t feet after t seconds.

The straight-line distance between the boy and the balloon is found as the hypotenuse of a right triangle with legs 15t and (45+5t). Using the Pythagorean theorem, that distance is ...

  d = √((15t)² + (45+5t)²)

Find an exponential function of the form y = ab* that passes through the points (0,4)
IrinaK [193]

Answer:

2nd option

Step-by-step explanation:

given an exponential function in the form y = ab^{x}

to find a and b use the coordinate points it passes through

using (0, 4 ) , then

4 = ab^{0} [ b^{0} = 1 ] , that is

a = 4 , so

y = 4b^{x}

using (2, 100 )

100 = 4b² ( divide both sides by 4 )

25 = b² ( take the square root of both sides )

\sqrt{25} = b , that is

b = 5

then exponential function is

y = 4 . 5^{x}
