Answer:

<em>h(x) = -3(x + 1)^2 + 8</em>

Step-by-step explanation:

<em>h=-3x^2-6x+5  subtract 5 from both sides</em>

<em />

<em>h-5=-3x^2-6x  divide both sides by -3</em>

<em />

<em>(5-h)/3=x^2+2x  halve the linear coefficient, square it, add it to both sides....</em>

<em />

<em>(2/2)^2=1 add 1 to both sides...</em>

<em />

<em>(5-h+3)/3=x^2+2x+1, now the right side is a perfect square...</em>

<em />

<em>(8-h)/3=(x+1)^2  multiply both sides by 3</em>

<em />

<em>8-h=3(x+1)^2  divide both sides by -1</em>

<em />

<em>h-8=-3(x+1)^2  add 8 to both sides</em>

<em />

<em>h=-3(x+1)^2+8</em>

h(x)= -3(x+1)^2+8

<em>BRAINLIEST PLS!!!</em>

Is 4/5 equal to 5/10?
vfiekz [6]
No, 4/5 does not equal to 5/10.

Because:- When you try to see if it is proportional, it does not equal it.

4/5 ≠ 5/10

Simplify to make sure.

4/5 ≠ 1/2

4/5 is NOT equal to 1/2.

Therefore, our final answer is that 4/5 does not equal 5/10.

Building A is 400 feet tall and Building B is 300 feet tall. Johnny is standing in between the two building. The angle of elevat
Free_Kalibri [48]

Answer:

389 feets apart

Step-by-step explanation:

Given that:

Building A

Height = 400feets

Angle of elevation = 70°

Building B:

Height = 300 feets

Angle of elevation = 52°

Distance from the foot of building A to where Jonny is standing = x (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 70 = 400/ x

2.7474774x = 400

x = 145.58809 feets

Distance from the foot of building B to where Jonny is standing = y (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 52 = 300/ y

1.2799416y = 300

y = 145.59

y = 234.38568 feets

x + y = distance between the two buildings

(145.58809 + 234.38568) feets

= 379.97377

= 380 feets apart

HELP PLEASE! The probability of drawing a penny from a bag of coins is 1/5. What is the probability of drawing a coin that is no
lutik1710 [3]
Okay so since with the penny it's 1/5 that means there's only one penny and 5 other coins and 100% is 5 then 80% will be 4 so your answer is 80% hope this helps

What are the missing reasons in the two-column proof?
Nesterboy [21]

Reasons:

1. Because, MO cuts Angle PMN in two equal parts.

2.As ∠PMN is cut in to equal parts thus:

∠PMN = ∠NMO + ∠PMO, where these two parts (∠NMO, ∠PMO) are equal.

3. Both are the same, common you can say..

4. Because, MO cuts Angle PON in two equal parts.

5. As ∠PON is cut in to equal parts thus:

∠PON = ∠NOM + ∠POM, where these two parts (∠NOM , ∠POM) are equal.

6. From the above statements, we have:

= ∠NMO + ∠PMO (Proved)

= ∠NOM + ∠POM (Proved)

= MO = MO (Proved)

Thus, ∆PMO ≅ ∆NMO, by AAS rule
