Answer: 1.  1*f*(x)-(-(x+4)^2-4)=0

STEP

1

:

Equation at the end of step 1

 fx - x2 - 8x - 12  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   fx-x2-8x-12  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*f*(x)-((x-1)^2)=0

STEP

1

:

1.1     Evaluate :  (x-1)2   =    x2-2x+1

Equation at the end of step

1

:

 2fx - x2 + 2x - 1  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   2fx-x2+2x-1  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25
t=5

So in 5 seconds the camera will hit the water.

I will mark you as brainliest if you're answer is correct​
GalinKa [24]

Answer:

perimeter = 28.13 cm

Step-by-step explanation:

Calculate the length of a line drawn from A to C.

sin 85 = b/8, b = 7.97

cos 85 = c/8, c = 0.697

AC² =7.97² + (6 + 0.697)² = 63.52 + 44.85 = 108.37

AC = 10.41

Now you have a right triangle ADC with a known hypotenuse and  one leg.

Using the Pythagorean theorem:

DC² = 10.41² - 5²

DC² = 108.37 - 25 = 83.37

DC = 9.13 cm

perimeter = 5 + 6 + 8 + 9.13 = 28.13 cm

The Lynn’s family bought a house for $75,300 a few years later they sold the house for $80,250 how much greater was the selling
Zepler [3.9K]

Buying price: $75,300

Selling price: $80,250

You want to find out how much more the selling price was when compared to the buying price.

To find the difference in prices, simply subtract the selling price with the buying price.

$80,250 (buying price) - $75,300 (selling price) = $4,950 (price difference)

The selling price is greater than the buying price of the house by $4,950
