I need help with this what would k be? Or is she correct

charle [14.2K]

Answer:

The value of k=1

So, Maura claim is incorrect. The value of k=1 and not k=1/2

Step-by-step explanation:

We need to determine the value of k if $2^4=16^k$

We are given:

$2^4=16^k$

Exponent rule, if bases are equal the exponents are equal

We can write $16= 2^4$

$2^4=(2^4)^k\\2^4=2^{4k}$

Now since the base is same, i,e 2 so, the exponents will be same

$4=4k\\k=1$

So, the value of k=1

So, Maura claim is incorrect. The value of k=1 and not k=1/2

Find the greatest number which divides by 1280 and 1371 leaves a remainder in each case?

vladimir1956 [14]

1279???
Because the gcf does not leave any remainders behind. The gcf could be 1280, but that would not leave a remainder behind if you divided 1280 by 1280. So, I think it is 1279, but i am probably wrong

There is a cereal box and the dimensions are 10 inches tall, 3 inches wide and 7 inches long. If you were to fill the box with c

JulsSmile [24]

Answer:

$6.30

Step-by-step explanation:

First, get the volume of the cereal box with the equation V = lwh.

V = 7(3)(10) = 210 cubic inches

Since it costs $.03 per cubic inch, multiply this cost by the volume to get the total cost to fill the box.

.03(210) = $6.30

Find the point slope equation for the line that passes through the points (7,-21) (-4,23)

zheka24 [161]

$\bf (\stackrel{x_1}{7}~,~\stackrel{y_1}{-21})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{23}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{23-(-21)}{-4-7}\implies \cfrac{23+21}{-11}\\\\\\ \cfrac{44}{-11}\implies -4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-21)=-4(x-7)\implies y+21=-4(x-7)$
