The order you have to work it out is is
Brackets
Indices
Divide
Multiply
Add
Subtract
There are no brackets or indices so you start with the dividing, then you add, then you subtract. This is called bidmas.

18/2=9
9+4=13
13-1=12

Komok [63]
The rules of exponents tell you to add exponents in the numerator and subtract those in the denominator. A power of a power causes the exponent to be multiplied.

\dfrac{(2x^{3}z^{2})^{3}}{x^{3}y^{4}z^2x^{-4}z^{3}}=2^{3}x^{(3\cdot3-3-(-4))}y^{-4}z^{(2\cdot3-2-3)}\\\\=\dfrac{8x^{10}z}{y^{4}}

which transformation causes the described change in the graph of the function y = cos x? the transformation results in a horizon
luda_lava [24]
The transformations that can occur to the graph of the function y = cos x that will exhibit changes would be changes to the angle, or changes to the coefficient. The transformations can be viewed as follows:

y = cos x transforms to y = cos (kx)

k > 1 ; a horizontal shrink occurs
0 < k < 1 ; a horizontal stretch occurs

y = cos x transforms to y = A cos x

|A| > 1 ; a vertical stretch occurs
|A| < 1 ; a vertical shrink occurs

The minimum value of f(x) = x3 – 3x2 – 9x + 2 on the interval [–4, 0] is
garri49 [273]

Answer:

-74

Step-by-step explanation:

Graph the function. See attached picture. Between the interval where -4 > x < 0, the graph rises up to a peak and descends back down when x = 0. This means the minimum value will be where x = -4.

Substitute x = -4 into the equation.

f(-4) = (-4)^3 -3(-4)^2 - 9(-4) + 2

f(-4) = -64 -3(16) +36 + 2

f(-4) = -64 - 48 + 36 + 2

f(-4) = -74

54 is 75% of what number?
Furkat [3]
<span>one way to solve this kind of problems is by doing a little bit of reversal 75 % * X = 54 75/100 * X = 54 (we move 75/100 to the right, since it's a fraction the top and bottom number will be reversed) X = 54 * 100/75 X = 5400 / 75 X = 72 Hope I helped! :) Cheers!</span>
