Answer:

-2, 1, 6 and 97

Step-by-step explanation:

Tn = n² - 3

First Term : T1 = (1)² - 3 = -2

Second Term : T2 = (2)² - 3 = 1

Third Term : T3 = (3)² - 3 = 6

Tenth Term : T10 = (10)² - 3 = 97

What is the final amount if 731 is increased by 7% followed by a 4% decrease? Give your answer rounded to 2 DP.
expeople1 [14]

Answer:

750.88 (rounded to 2 d.p.)

Step-by-step explanation:

100% --- 731

100% + 7% --- \frac{100+7}{100} × 731 = 782.17

100% --- 782.17

100% - 4% --- \frac{100-4}{100} × 782.17 = 750.88 (rounded to 2 d.p.)

Find an equation of the plane tangent to the following surface at the given point.z equals tangent Superscript negative 1 Baseli
Sergeeva-Olga [200]

Let <em>f(x</em>, <em>y</em>, <em>z)</em> = <em>z</em> - arctan(<em>x y</em>). Compute the gradient of <em>f</em> at the point (0, 3, 0):

∇ <em>f(x</em>, <em>y</em>, <em>z)</em> = (-<em>y</em> / (1 + <em>x</em>²<em>y</em>²), -<em>x</em> / (1 + <em>x</em>²<em>y</em>²), 1)

∇ <em>f </em>(0, 3, 0) = (-3, 0, 1)

This vector is orthogonal to the surface <em>z</em> = <em>f(x</em>, <em>y)</em>. Then the equation of the tangent plane is

∇ <em>f </em>(0, 3, 0) • (<em>x</em>, <em>y</em> - 3, <em>z</em>) = 0

(-3, 0, 1) • (<em>x</em>, <em>y</em> - 3, <em>z</em>) = 0

-3<em>x</em> + <em>z</em> = 0

<em>z</em> = 3<em>x</em>
