Answer: The shadow of the 26ft tree is 5 1/5ft

Step-by-step explanation: A 40ft tree with a 16 ft shadow would have a shadow that is 2/5 the length of the tree so you would need to find 2/5 of 26 feet which would be 5 1/5ft

Answer:

$7200 in the fund rose 6% n $2800 in the fund rose 9%

Step-by-step explanation:

let x be the amount in the fund rose 6%

gain in one year=x*6%=0.06x

total amount is 10000

so amount in the fund rose 9% = 10000-x

gain in one year=(10000-x)*9%=900-0.09x

total gain=0.06x+900-0.09x=900-0.03x

=684

900-684=0.03x

0.03x=216

x=7200

the other fund amount=10000-7200=2800

What are the solution(s) to the quadratic equation 50 – x2 = 0?

Dmitrij [34]

Answer:

x = ± $5\sqrt{2}$

Step-by-step explanation:

We have been given the quadratic equation;

$50-x^{2}=0$

The first step is to subtract 50 from both sides of the equation;

$50-x^{2}-50=0-50$

$-x^{2}=-50$

Multiplying both sides by -1 yields;

$x^{2}=50$

The final step is to obtain square roots on both sides;

$\sqrt{x^{2} }=\sqrt{50}\\x=+/-\sqrt{50}$

Therefore, x = ± $5\sqrt{2}$
