Sarah has 273 feet of wire to make bead necklaces. If each necklace requires 1 2/3 feet of wire, how many necklaces can she make
o-na [289]

Oh boy, here we go again

First we must convert  1 2/3 to an improper fraction.  By doing this, we get 5/3  (3/3 + 2/3)

So now we have 273 /  5/3

To divide this easier we can do something that when I learned it was called (keep, change, flip)  which basically means keep the first fraction, change the sign from division to multiplication, and flip the second fraction

This now turns into:  273/1 * 3/5

Combine 273 and 3/5

273⋅3/5

Multiply 273

by 3

819/5

is your answer

Write the following equation in slope intercept form. y – 3 = -2 (x -5)
Phantasy [73]
This equation is currently in Point Slope Form. You can easily convert this form to Y Slope Intercept by following these steps.

Add 3 to both sides.

y = -2(x-2)

Simplify.

y = -2x + 4

Someone explain this to me
e-lub [12.9K]

Answer: a) y = f(x - 6)

              b) y = f(x) - 2

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

For transformations we use the following formula: y = a f(x - h) + k

  • a = vertical stretch
  • h = horizontal shift (positive = right, negative = left)
  • k = vertical stretch (positive = up, negative = down)

a) f(x) has a vertex at (-1, 1)

    M has a vertex at (5, 1)

    The vertex shifted 6 units to the right  → h = +6

Input h = +6 into the equation and disregard "a" and "k" since those didn't change.     ⇒ y = f(x - 6)

b) f(x) has a vertex at (-1, 1)

    N has a vertex at (-1, -1)

    The vertex shifted down 2 units  → k = -2

Input k = -2 into the equation and disregard "a" and "h" since those didn't change.     ⇒ y = f(x) - 2

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h ( t ) = − 4.
Aleks [24]

Answer:

A.) 24.08 seconds

B.) 825.42 metres

Step-by-step explanation:

function of time is given as

h ( t ) = − 4.9 t 2 + 118 t + 115 .

Where a = -4.9, b = 118, c = 115

Let's assume that the trajectory of the rocket is a perfect parabola.

The time t the rocket will reach its maximum height will be at the symmetry of the parabola.

t = -b/2a

Substitute b and a into the formula

t = -118/-2(4.9)

t = 118/9.8

t = 12.041 seconds

Since NASA launches the rocket at t = 0 seconds, the time it will splash down into the ocean will be 2t.

2t = 2 × 12.041 = 24.08 seconds

Therefore, the rocket splashes down after 24.08 seconds.

B.) At maximum height, time t = 12.041s

Substitute t for 12.041 in the function

h ( t ) = − 4.9 t 2 + 118 t + 115

h(t) = -4.9(12.041)^2 + 118(12.041) + 115

h(t) = -4.9(144.98) + 118(12.041) + 115

h(t) = -710.402 + 1420.82 + 115

h(t) = 825.42 metres

Therefore, the rocket get to the peak at 825.42 metres
