Answer:

D. x = -2; x = 3/4

Step-by-step explanation:

  • Read the values of a, b, and c from the quadratic equation:
  • a is the number in front of x^2, b is the number in front of x, c is the number at the end. In our case: a = 4,b = 5,c = −6 The formula for the roots is =  \frac{-b +-\sqrt{b^{2}-4ac } }{2a\\}

11 The net force on a vehicle that is accelerating at a rate of 1.5 m/s² is 2,800 newtons. What is
ololo11 [35]

Answer:

Mass = 1867kg

Step-by-step explanation:

Given

Force = 2800N

Acceleration = 1.5m/s^2

Required

Determine the mass of the vehicle

This question will be answered using Newton's second law

Force = Mass * Acceleration

Substitute values for Force and Acceleration

2800 = Mass * 1.5m/s^2

Make Mass the subject

Mass = \frac{2800N}{1.5m/s^2}

Mass = 1866.6667kg

Mass = 1867kg ---- approximated

<em>Hence, the mass of the vehicle is 1867kg</em>

The Eiffel Tower is 324 m tall. If a tourist is looking at it from 100 m away from the base,
romanna [79]

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

tan=\frac{opposite side}{adjacent}

tan=\frac{324}{100} =3.24

And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).

I hope it helped.

Find the value of x .. assume that segments that appear to be tangent are tangent .
Rus_ich [418]

Answer:

sqrt(277) =x

x is approximately 16.64331698

Step-by-step explanation:

This is a right triangle since 14 is tangent to the circle and 9 is a radius

We can use the Pythagorean theorem to solve this problem

a^2 +b^2 =c^2

9^2+14^2 =x^2

81+196 = x^2

277 = x^2

Taking the square root of each side

sqrt(277) = sqrt(x^2)

sqrt(277) =x

Can someone please help me?
Pachacha [2.7K]

Hello there!

So, remember that m = the slope, and slope intercept form is represented as y = mx + b. To find the y intercept, place the values of x, y, and the slope into the equation.

The first step, ____ = (____)____ + b should look like 3 = (2/5)10 + b once you plug the values for your x and y values and slope.

The second step, ___ = ____ + b should look like 3 = 4 + b since you should multiply 2/5 x 10.

The final step, -1 = b should look like  since you subtracted 4 from both sides of the equation.

Y = 2/5x - 1 is your final equation. I hope this helps, have a great rest of your day!
