9514 1404 393

Answer:

  • Washington: 115 hits
  • Sanchez: 105 hits

Step-by-step explanation:

Let w represent the number of hits Washington got. Then their total is ...

  w + (w -10) = 220

  2w = 230

  w = 115 . . . . . . . the number of Washington's hits

  w -10 = 105 . . . the number of Sanchez's hits

Eli invested $ 330 $330 in an account in the year 1999, and the value has been growing exponentially at a constant rate. The val
Cloud [144]

Answer:

The value of the account in the year 2009 will be $682.

Step-by-step explanation:

The acount's balance, in t years after 1999, can be modeled by the following equation.

A(t) = Pe^{rt}

In which A(t) is the amount after t years, P is the initial money deposited, and r is the rate of interest.

$330 in an account in the year 1999

This means that P = 330

$590 in the year 2007

2007 is 8 years after 1999, so P(8) = 590.

We use this to find r.

A(t) = Pe^{rt}

590 = 330e^{8r}

e^{8r} = \frac{590}{330}

e^{8r} = 1.79

Applying ln to both sides:

\ln{e^{8r}} = \ln{1.79}

8r = \ln{1.79}

r = \frac{\ln{1.79}}{8}

r = 0.0726

Determine the value of the account, to the nearest dollar, in the year 2009.

2009 is 10 years after 1999, so this is A(10).

A(t) = 330e^{0.0726t}

A(10) = 330e^{0.0726*10} = 682

The value of the account in the year 2009 will be $682.

A 14.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the fire truck)
UkoKoshka [18]

Answer:

h = 7.47 m

Step-by-step explanation:

According to the question, we have a right triangle formed by the ladder with the wall and the floor.

The length of the ladder is the hypotenuse and the desired height is the opposite. This is due to the fact that "the ladder makes an angle of 21" 27" with the horizontal". Then, the trigonometric ratio to use is sine:

sin(\theta)=\frac{opposite}{hypotenuse}

Using the values given:

sin(\21"27")=\frac{h}{14.5}

Multiplying both sides by 14.5:

14.5*sin(\21"27")=14.5*\frac{h}{14.5}

14.5*sin(\21"27")=h

Then h = 7.47 m

3(x-1)=2x+9. Solve equation
Anna11 [10]

Hello.

In order to solve this equation, we need to isolate the variable (in this case, the variable is x)

The first step is to use the Distributive Property and distribute 3:

\mathrm{3(x-1)=2x+9}

\mathrm{3x-3=2x+9}

Now, add 3 to both sides:

\mathrm{3x-3+3=2x+9+3}

\mathrm{3x=2x+9+3}

\mathrm{3x=2x+12}

Now, subtract 2x from both sides:

\mathrm{3x-2x=2x-2x+12}\\\mathrm{3x-2x=12}

\mathrm{x=12}

Therefore, the answer is

\mathrm{x=12}

I hope it helps.

Have a nice day.
