The velocity, V, of a specific object being dropped from a particular height, h, can be found by the radical function V equals t

he square root of the quantity 2 times h times a end quantity where a represents the acceleration in ft/sec2. If the acceleration due to gravity is 32.2 ft/sec2, at what height should you drop an object in order for it to have a velocity of 80 ft/sec? 5,152 feet 99.4 feet 71.8 feet 1.5 feet

<u>Complete Question:</u>

A park in the shape of a right triangle is set in the middle of 3 square rose gardens, with one garden along each side. Which statement is true about the 3 gardens?

A) The area of Garden B minus the area of Garden C is equal to the area of Garden A.

B) The area of Garden B plus the area of Garden C is equal to twice the area of Garden A.

C) The area of Garden C minus the area of Garden B equals the area of Garden A.

D) The area of Garden C minus the area of Garden A is equal to twice the area of Garden B.

<u>Correct Answer:</u>

The area of Garden C minus the area of Garden B equals the area of Garden A.

Thus, (C) is the correct option.      

<u>Step-by-step explanation:</u>

According to question , a right angle triangle with right angle at R and A is perpendicular , B is base and C is hypotenuse  of the triangle.

One square garden along  each side of triangle.

Area of square = Side × Side

So area of each square garden is :

A ( A) = A^2\\B ( B) = B^2\\C ( C )= C^2

According to Pythagoras theorem,

In  a right angle triangle, square of hypotenuse is equal to  sum of square of the remaining two sides.

By figure,

A^2 + B^2 = C^2

Area of garden A + area of garden B = Area of garden C

A^2 =  C^2 -B^2

The area of Garden C minus the area of Garden B equals the area of Garden A.

Thus, (C) is the correct option.

jasenka [17]
The equation would be y = (x+4)² + 7

Because adding 4 to 'x' creates a transformation 4 units left and adding 7 to the whole function moves the parabola up 7

Hope this helps!

Quadrilateral RJFT is similar to quadrilateral SYPA . JF=60 mm , AP=40 mm , and YP=25 mm . What is TF ?
Hoochie [10]
The two quadrilaterals are similar. Which means the ratios of respective sides of two quadrilaterals will be the same. 

So, for the given quadrilaterals, ratio of sides JF and TF of quadrilateral RJFT will be equal to the ratio of sides YP and AP of quadrilateral SYPA. Mathematically, we can write:

JF:TF = YP:AP \\  \\ &#10; \frac{JF}{TF} = \frac{YP}{AP}  \\  \\ &#10; \frac{60}{TF} = \frac{25}{40}  \\  \\ &#10;60* \frac{40}{25}=TF \\  \\ &#10;TF=96mm

So the measure of TF will be 96mm

Please help me simplify these expressions
Fantom [35]

Answer:

1.  -18x¹¹

2.  3n⁷

Step-by-step explanation:

For these problems, there are two things you need to worry about: negative signs and exponents.

1. Let's look at the signs first.  There is only one value with a negative sign, meaning that the negative sign will stay.

When multiplying with exponents, you have to add up the exponents.  Don't forget the numerical coefficients.

-3x² · 3x · 2x³ · x⁵ = -18x¹¹

2.  There are two negative signs in this probem, meaning that they will cancel out.  Multiply the rest like we did in the first problem.

3n² · -n² · -n³ = 3n⁷
