Answer:

y = 6x - 11

Step-by-step explanation:

An arithmetic sequence is a linear function. This means it steadily increases or decreases through addition/subtraction by a constant amount. Here the sequence grows by adding 6 each time.

-11 + 6 = -5

-5 + 6 = 1

1 + 6 = 7

etc....

Since this is linear, its equation has the form y = mx + b where m is the slope and b is the y-intercept. The slope is m = 6 and b = -11.

y = 6x - 11

Irina-Kira [14]

Answer:

t=0

Step-by-step explanation:

r=< $at^2$ +1, $t$ >

by differentiating the r vector component by component

r' = <2at, 1>

Two vector are orthogonal when the dot product between them is zero, so:

r'·r=0

< $at^2$ +1, $t$ >·<2at, 1>=2 $a^2t^3$ +2at+t=0

common factor

t( $2a^2t^2$ +2a+1)=0

Then, the only real value for t is zero.

-> t=0

I will give a brainliest to the person who has gets the correct answer with an explanation of how you solved it.

frutty [35]

Answer: $V = 24,416.64m^{3}$

Step-by-step explanation:

Solve for v by simplifying both sides of the equation, then isolating the variable.

Formula: $v = \frac{4}{3} \pi r^{3}$

Plugin the variable: $v = \frac{3}{4}\pi (18^{3})$

Solve:

$v = \frac{4}{3} 3.14 (5,832)$

$v = 4.18666666(5,832)$

$V = 24,416.64m^{3}$
