Answer:

D. Translation 1 unit up and 5 units to the right, followed by a reflection across the x-axis

Step-by-step explanation:

→ Point B moves up to [-2, -4]

Translation up:

→ Point A moves up to [-5, -1]

→ Point B moves up to [3, -4]

Translation to the right:

→ Point A moves up to [0, -1]

→ [3, -4] >> B'[3, 4]

Reflections:

→ [0, -1] >> A'[0, 1]

This is a genuine statement!

I am joyous to assist you anytime.

Naddik [55]

240 = 16x is about an equation but you can make it more complicated by adding unneeded parts for example 240 = 16x - 81 + ((15x) + 15) - (x^2 / 2) - 45 - 1.5.

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:

The correct equation is

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

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

$74.683\ foot-pounds$

Please help me with Part A and B!

Illusion [34]

Answer:

A. When Katina has $280 in her bank account, 4 months have passed. Plug 4 months into Malorie's bank account equation:

a = 50(4) + 100

a = 200 + 100

a = $300

B. Malorie's bank account changes at a greater rate. Katina's bank account amount increases by $20 each month, whereas Malorie's bank account increases by $50.

Ex: month 5

Katina has 300, 20 more than the previous month.

Malorie has 350, 50 more than the previous month
