Answer:

You would need to use the Pythagorean Theorem

Step-by-step explanation:

First, you would want to take the Hypotenuse of 3 and square. Do the same for the 2.25. After that, you want to put in a calculator (Desmos Graphing Calculator) √3²-2.25² adn get the answer for the line of C and D (-2.06). After that, you do the same but on the other side: Take the Hypotenuse of 4 and the -2.06 and form it into √4² -2.06². Your final answer would be...

x = 3.43

Answer:

Both triangles are right triangles because the angle d is 90 degrees in both sides

3 ^ 2 - 2.25^2 = 1.98

4^2 - 1.98^2 = 3.48

x = 3.48

Write the equation of the line that passes<br> through the points (3, 1) and (-2, 6).
tia_tia [17]

Answer:

Equation is Y=mx+c (that's how I know it, it may differ)

Step-by-step explanation:

First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x

6-1 /-2-3 = 5/-5

= -1

So now u gotta find c, C= Y-mx

And u have got two brackets, which have an x and y, and u now have m.

Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2

So C =4

The equation now is : Y = - 1x + 4

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

To graphically add two vectors, V + W, using the tip-to-tail method, place the tail of w to the tip of v.O TrueO False
Vilka [71]

In the tip to tail method of ading vectors, the tail of a second vector is moved to the tip(head) of the first vector.

So, in the addition of vectors, V+W, the tail of W is placed to the tip of V.

So, the given statement is true.

Ksju [112]

Answer:

The balance in the cash account at the beginning of last month = $5900


Step by step explanation

The cash account of a company had an ending balance of $6,750

Cash  in the beginning of last month = Ending cash balance + credit - debit

= $6750 + $10,500 - $11, 350

= $17250 - $11, 350

= $5900

Therefore, beginning cash balance is $5900


Thank you.
