The answer is 65 I'm pretty sure because a reflection is a rigid motion and a rigid motion preserves angle measure and distance so the angle measure of BCD will be the same as angle measure B'C'D'

Is 21.8 x 10 to the power of 8 a scientific notation
Oksanka [162]

Answer:

\large\boxed{2.128\times10^9}

Step-by-step explanation:

The scientific notation:

a\cdot10^k\\\\1\leq a

We have:

21.8\times10^8

21.8 >10

21.8 = 2.18 × 10

Thereofre:

21.8\times10^8=2.18\times10\times10^8

Use

a^n\cdot a^m=a^{n+m}

21.8\times10^8=2.18\times10^1\times10^8=2.18\times10^{1+8}=2.18\times10^9

AUTOMOBILES The engine torque y (in foot-pounds) of one model of car is given by y = º3.75x2 + 23.2x + 38.8 where x is the speed
Scilla [17]

Answer:

Part 1) The engine speed that maximizes torque is 3,093 rev/min

Part 2)The maximum torque is 74.683\ foot-pounds

Step-by-step explanation:

<u><em>The correct equation is</em></u>

y=-3.75x^{2}+23.2x+38.8

This is the equation of a vertical parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

The x-coordinate of the vertex represent the engine speed that maximizes torque

The y-coordinate of the vertex represent the maximum torque

Solve the quadratic equation by graphing

using a graphing tool

The vertex is the point (3.093,74.683)

see the attached figure

therefore

The engine speed that maximizes torque is

3.093(1,000)=3,093 rev/min ---> because is in thousands of revolutions per minute

The maximum torque is

74.683\ foot-pounds
