Presumably d meanst distance and t means time.

When t = 1, d = 2.5
When t = 3, d = 4

d = mt + b
2.5 = m + b [t = 1]
4.0 = 3m + b [t = 2]
1.5 = 2m [subtract]
m = .75 = slope
b = 1.75 = d-intercept
d = .75t + 1.75
d = 15/4 + 7/4 [t = 5]
d = 22/4 = 5.5 m from sensor

What is the axis of symmetry for f(x) = 2x2 − 8x 8? x = −2 x = −3 x = 3 x = 2
Tatiana [17]

<span>The first part of the quadratic formula, x = - b/2a, is the equation of the axis of symmetry, and the x-coordinate of the vertex. </span>

<span>In standard form: - 2x² + 8x - 5 = 0, a = - 2, b = 8, c = - 5 </span>

<span>The axis of symmetry: x = - 8/2(- 2) = - 8/- 4 = 2 </span>

<span>Go back and solve for y to find the y-coordinate of the vertex. </span>

<span>y = - 2(2)² + 8(2) - 5 </span>

<span>y = - 2(4) + 16 - 5 </span>

<span>y = - 8 + 16 - 5 </span>

<span>y = 3 </span>

<span>Vertex is (2, 3)</span>

-20t^5u^2v^3<br> ———————-<br> 48t^7u^4v
Marat540 [252]

Answer:

B. \frac{-5v^2}{12t^2u^2}\\

Step-by-step explanation:

Recall:

\frac{a^x}{a^y} = a^{x -y}\\

a^{-x} = \frac{1}{a^x}\\

Solution:

\frac{-20t^5u^2v^3}{48t^7u^4v} \\ \frac{-20}{48} \cdot t^{5 -7} u^{2 -4} v^{3 -1} \\ -\frac{5}{12} \cdot t^{-2} u^{-2} v^2 \\ -\frac{5v^2}{12t^2u^2}
