Answer:

  • 1400 mi

Step-by-step explanation:

The triangle CHE is right, angle CHE is marked as right angle.

<u>We have:</u>

  • CD= CH = 3960 mi
  • DE = 240 mi
  • EH = ?

<u>Use Pythagorean theorem to find the value of EH:</u>

  • CE² = CH² + EH²
  • CE = CD + DE = 3960 + 240 = 4200

<u>Substitute known values and solve for EH</u>

  • 4200² = 3960² + EH²
  • EH² = 4200² - 3960²
  • EH² = 1958400
  • EH = √1958400
  • EH = 1399.42 ≈ 1400 mi (rounded)

spencer took 21$ with him to the mall. At the music store, he spent 2/3 of his money on a DVD, he spent 1/4 of what he had left
Sunny_sXe [5.5K]

Answer:

$5.25 Dollars

Step-by-step explanation:

I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)

<em>Hope this helped! :)</em>

The function f(x)=-10(x)(x-4) represents the approximate height of a projectile launch on the ground into the air as a function
ELEN [110]

Answer:

4 seconds.

Step-by-step explanation:

The function f(x)=-10(x)(x-4) ........ (1), represents the approximate height of a projectile launch on the ground into the air as a function of time in seconds x.

Now, we are asked that for how long from the launch does the projectile stays in the air.

Therefore, we have to solve the equation (1) making f(x) as zero.

Hence, 10x(x - 4) = 0

⇒ x = 0 or x = 4

(As x can not be zero since at x = 0 sec, the projectile was at the ground.}

Hence, x = 4 seconds.

Therefore, the projectile was in the air for 4 seconds. (Answer)
