Answer:

0.5 ft per min

Step-by-step explanation:

in 80 minutes the radius expanded by 40%

we can set up a proportion of percent change over minutes:

.4/80 = r/1

cross-multiply to get:

80r = .4

r = .005 or 1/2 of a foot per minute.

Hope It Helps :)

*SOMEONE WHO CAN SIMPLY ORDER INTERVALS!*
OlgaM077 [116]

Answer:

2.5 seconds.

Step-by-step explanation:

Find the value of t when the height is 28 feet:

-16t^2 + 56t + 4  = 28

-16t^2 +  56t - 24 = 0

-8(2t^2 - 7t + 3) = 0

-8(2t - 1)(t - 3) = 0

t = 0.5,  3 seconds.

So on the upward journey the rock is at 28 feet at 0.5 second after the throw and at 3 seconds it is at 28 feet again  while it is falling back.

Therefore the period when it is at least 28 feet above the ground is 3.0 - 0.5 = 2.5 seconds.

given two angles that measure 50 and 80 and a side that measures 4 feet how many triangles if any can be constucted
Ierofanga [76]

There is only one triangle possible having angle 50, 50, 80.

<h3>What is isosceles triangle?</h3>

An Isosceles Triangle has the following properties:

  • Two sides are congruent to each other.
  • The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.
  • The two angles opposite to the equal sides are congruent to each other.

It is given that, 2 angles of a triangle as:

∠1 = 50°

∠2 = 80°

Now we know the Angle sum property of a triangle that sum all three interior angle in a triangle is 180^{0}.

i.e., ∠1+∠2+∠3= 180^{0}.

So, 50° +80°+ ∠3 = 180^{0}

                       ∠3 =  50°

As two angles of the triangle are equal that means it is a isosceles triangle.

There is no possibility of getting a right angles triangle.

Hence, there is only one triangle possible with these measurements .
