|-4| + |-5| i need help!!!

iren2701 [21]

Answer:

Step-by-step explanation:

The absolute value of any number is just its distance from 0.

-4 is 4 away from 0, so its absolute value is 4.

-5 is 5 away from 0, so its absolute value is 5.

Therefore, the equation is basically just asking what is 4 + 5, which is 9 :D.

Answer:

d) The probability spinner will land on black all three times is 1/8

Step-by-step explanation:

The probability of landing on black = 1/2

The probability of landing on red = 1/3.

Now, if the spinner is spun 3 times.

The probability it will land on black all three times

= $\textrm{ (The probability of landing on black)}^3$

= $\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{2 \times 2 \times 2 } = \frac{1}{8}$

Hence, the probability spinner will land on black all three times is 1/8.

Use Theorem 7.4.1. THEOREM 7.4.1 Derivatives of Transforms If F(s) = ℒ{f(t)} and n = 1, 2, 3, . . . , then ℒ{tnf(t)} = (−1)n dn

Answer:

$L\left(te^{2t }sin3t\right)=\frac{6s-12}{(s^2-4s+13)^2}$ .

Step-by-step explanation:

If F(s)= L{f(t)}

Then $L\left\{(t^nf(t)\right\}=(-1)^n\frac{\mathrm{d^n}F(s)}{\mathrm{d^n}s}$

$L\left\{te^{2t}sin3t\right\}$

f(t)= $e^{2t}sin3t$

$L\left\{e^{at}sinbt\right\}=\frac{b}{(s-a)^2+b^2}$

Therefore, $L\left\{e^{2t}sin3t\right\}=\frac{3}{(s-2)^2+(3)^2}$

$L\left\{e^{2t}sin3t\right\}=\frac{3}{s^2-4s+13}$

$L\left\{te^{2t}sin3t\right}=-\frac{\mathrm{d}F(s)}{\mathrm{d}s}$

=- $\frac{\mathrm{d}e^{2t}sin3t}{\mathrm{d}s}$

$L\left\{te^{2t}sin3t\right\}$

$=\frac{3(2s-4)}{(s^2-4s+13)^2}$

$L\left\{te^{2t}sin3t\right\}=\frac{6s-12}{(s^2-4s+13)^2}$ .
