Y= -1/2(x+10)^2+14 Find the range
Andre45 [30]

Answer:

Step-by-step explanation:

y=-1/2(x+10)^2+14

2y=-(x+10)^2+28

(x+10)^2=28-2y

L.H.S.  is  positive.

zvonat [6]

Answer:

$15.00

Step-by-step explanation:

Suppose 1 rose bush costs r dollars,

Suppose 1 geranium costs g dollars.

Here are 2 equations:

1)6r+14g=146

3r+7g=73

2)r+7g=57

r=57-7g

Put 2) in 1)

3(57-7g)+7g=73

171-21g+7g=73

98=14g

g=7

r=8

7+8=$15.00

Hope I helped!

Which of the following is equivalent to
enot [183]

Answer:

Option (2) is correct.

18-\sqrt{-25}=18-5i

Step-by-step explanation:

Given expression 18-\sqrt{-25}

We have to find an equivalence value to the expression.

<u> Radical rule</u>,

\sqrt{-a}=\sqrt{-1} \sqrt{a}

Also,i=\sqrt{-1}

Consider the given expression,

18-\sqrt{-25}

Applying radical rule to \sqrt{-25}

\sqrt{-25}=\sqrt{-1}\sqrt{25}=5i

Thus, the expression becomes,

18-\sqrt{-25}=18-5i

Thus, option (2) is correct.
