Answer:

$16x^{4}$

Step-by-step explanation:

$(a^{m})^{n}=a^{m*n} \\\\\\$ and $(a*b)^{m}= a^{m}*b^{m}$

$(-4x^{2})^{2} = (-4)^{2} *(x^{2})^{2}\\\\\\=16 * x^{2*2}\\\\=16x^{4}$

Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho

gulaghasi [49]

$1813\times10^9$ cells were not burnt when Jennie escaped from the fire.

<u>Solution:</u>

Given:

2% of skin cells were burnt i.e, $3.7\times10^{10}$ of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write $3.7\times10^{10} \text{ as } 37\times10^{9}$

Therefore, by equating the values we get,

2% of the cell is $37\times10^9$

1% of the cell is $\frac{37\times10^9}{3}=18.5\times10^9$

As, 1% of the cell is $18.5\times10^9$

98% of the cell will be $98\times18.5\times10^9=1813\times10^9$

$\therefore \text{ skin cells that are not burnt is } 1813\times10^9$

Select the equations that are parallel and perpendicular to y = −3x − 1 and that pass through the point (3, 1).

NemiM [27]

I think that that the answer is B because the slopes of parallel lines are the same but the slopes of perpendicular lines are related such that the slope of line B = the reciprocal of line A with a different sign either positive or negative
