The slope of the normal curve y=3x^2-5x is at the point (0,0)
Rufina [12.5K]

Answer:

\frac{1}{5}

Step-by-step explanation:

Consider the curve y=3x^2-5x

Differentiate with respect to x

\frac{dy}{dx} =3(2x)-5=6x-5

( Use \frac{d}{dx}(x^n)=nx^{n-1} )

Slope of normal curve is given by \frac{-1}{\frac{dy}{dx} }

Slope of normal curve = \frac{-1}{6x-5}

To find slope of normal curve at point (0,0) ,put x=0 in \frac{-1}{6x-5}

Slope of normal curve at point (0,0) = \frac{-1}{6(0)-5} =\frac{-1}{-5}=\frac{1}{5}

Identify the correct explanation and the similarity statement for the similar triangles.
Tatiana [17]

Answer:

Option B

Step-by-step explanation:

From the picture attached,

In ΔABC,

m∠B = m∠C = 75° [Isosceles triangles]

By applying triangle sum theorem,

m∠A + m∠B + mC = 180°

m∠A + 75° + 75° = 180°

m∠A = 180° - 150°

m∠A = 30°

In triangle PQR,

m∠P = m∠Q [Isosceles triangle]

By applying triangle sum theorem,

m∠P + m∠Q + m∠R = 180°

2(m∠P) + 30° = 180°

m∠P = 75°

m∠P = m∠Q = 75°

In ΔABC and ΔRPQ,

m∠B ≅ m∠Q [Given]

m∠C ≅ m∠R [Given]

Therefore, by AA property of similarity of two triangles, both the triangles will be similar.

ΔABC ~ ΔRPQ

Option B will be the answer.

<h2><u>ABSOLUTE VALUE</u></h2>

The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.

<h3>Exercise</h3>

Replace the value of x:

| x - 8 |

| -4 - 8 |

| -12 | = \large{\boxed{12}}

The absolute value of a number is the numerical value of the number, without regard to its sign.
