Answer:

A) y = x² - 8x + 15

Step-by-step explanation:

We can see that the roots of this equation (the x-intercepts) are at x = 3 and x = 5. Plugging this into factored form gives us

y = (x-r₁)(x-r₂)

y = (x-3)(x-5)

Multiplying, we have

y = (x)(x)-5(x)-3(x)-3(-5)

y = x²-5x-3x--15

y = x²-8x+15

Answer:

Step-by-step explanation:

Given

$\left[\begin{array}{ccc}-2&3\\2&4\\\end{array}\right]$ + $\left[\begin{array}{ccc}3&1\\-1&2\\\end{array}\right]$

Add corresponding elements to obtain the sum, that is

= $\left[\begin{array}{ccc}-2+3&3+1\\2-1&4+2\\\end{array}\right]$

= $\left[\begin{array}{ccc}1&4\\1&6\\\end{array}\right]$ → C

Please help me:

Tasya [4]

Answer:

6 units

Step-by-step explanation:

This coordinate is a three dimensional coordinate, which involves positive and negative x,y, and z axis.

The y axis is from left to right, i.e from negative to positive.

So 6 unit left is = -6 but it explains moving left .

Thank you

Find the inverse laplace<br><br> F(s)=11s/ s^2-12s+52

lions [1.4K]

Answer:

$11e^{6t}\cos 4t+\frac{33}{2}e^{6t}\sin 4t$

Step-by-step explanation:

We can write $\frac{11s}{s^2-12s+52}$ as follows:

$\frac{11s}{s^2-12s+52}\\=11\left [ \frac{s}{s^2-12s+52} \right ]\\=11\left [ \frac{s}{(s-6)^2+16} \right ]\\=11\left [ \frac{s-6+6}{(s-6)^2+16} \right ]\\=11\left [ \frac{s-6}{(s-6)^2+16} \right ]+\frac{66}{(s-6)^2+16}$

To find:

$L^{-1}\left [ \frac{11s}{s^2-12s+52 \right ]}\\=L^{-1}\left [ 11\left [ \frac{s-6}{(s-6)^2+16} \right ]+\frac{66}{(s-6)^2+16} \right ]$

We will use formulae:

$L^{-1}\left \{ \frac{s-a}{(s-a)^2+b^2} \right \}=e^{at}\cos bt\\L^{-1}\left \{ \frac{b}{(s-a)^2+b^2} \right \}=e^{at}\sin bt$

we get solution as :

$L^{-1}\left [ 11\left [ \frac{s-6}{(s-6)^2+16} \right ]+\frac{66}{(s-6)^2+16} \right ]\\=L^{-1}\left [ 11\left [ \frac{s-6}{(s-6)^2+4^2} \right ]+\frac{66}{4}\left [ \frac{4}{(s-6)^2+4^2} \right ] \right ]\\=11e^{6t}\cos 4t+\frac{33}{2}e^{6t}\sin 4t$
