Answer:

SNITCHY SNATCH

Step-by-step explanation:

I actually don't know how to show how to graph it. Sorry. But I can give a few coordinates. For y < 1/3x + 3: (-1,2 2/3) (0,3) (1,3 1/3). For y > -2/3x - 3: (-1,-2 1/3) (0,-3) (1,-3 2/3).

stira [4]

Answer:

s= 30000+1500x

Step-by-step explanation:

Given data

Le the number of years be x

His salary for the first year is $30,000

5% of $30,000

=5/100*30000

= 0.05*30000

= $1500

Hence for x years the salary can be described as

s= 30000+1500x

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is $v(3) = 29.4 \ m/s$

Step-by-step explanation:

From the question we are told that

$s(t) = -4.9t^2 + 500$

And

$\lim_{t \to a} \frac{s(a) - s(t)}{a-t}$

Generally s(t) at t = a is mathematically evaluated as

$s(a) = -4.9a^2+ 500$

$s(a) - s(t) = -4.9a^2 + 500 - ( -4.9t^2+500)$

$s(a) - s(t) = -4.9a^2 + 500 +4.9t^2-500)$

$s(a) - s(t) = 4.9(t^2 - a^2)$

Thus the velocity is represented as

$v(t) =\lim_{t \to a} \frac{s(a) - s(t)}{a-t} \equiv \lim_{t \to a} \frac{4.9(t^2 - a^2 )}{ a-t}$

=> $v(t) = \lim_{t \to a} - 4.9(a + t )$

=> $v(t) = -4.9 (a + a )$

=> $v(t) = -9.8a$

Now at t = 3

=> $v(3) = -9.8 (3)$

=> $v(3) = 29.4 \ m/s$

Which expression is equal to 254−−√−424−−√ ?

hichkok12 [17]

Answer:

$-2\sqrt{6}$

Step-by-step explanation:

<u><em>The correct expression is</em></u>

$2\sqrt{54}-4\sqrt{24}$

we know that

$54=(2)(3^3)=(3^2)(2)(3)=(3^2)(6)$

$24=(2^3)(3)=(2^2)(2)(3)=(2^2)(6)$

substitute in the expression above

$2\sqrt{(3^2)(6)}-4\sqrt{(2^2)(6)}=2(3)\sqrt{6}-4(2)\sqrt{6}=6\sqrt{6}-8\sqrt{6}=-2\sqrt{6}$
