-5/6x-7/30x+1/5x-52 please help me guys cuz imk not good with math

Marina CMI [18]

Answer:

$\frac{-13}{15} x-52$

Step-by-step explanation:

$\frac{-5}{6}x-\frac{7}{30}x+\frac{1}{5}x-52$

$=\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x+-52$

Combine Like Terms:

$=\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x+-52$

$=(\frac{-5}{6}x+\frac{-7}{30}x+\frac{1}{5}x)+(-52)$

$=\frac{-13}{15}x+-52$

Therefore, $\frac{-13}{15}x+-52$ will be your final answer.

Find the range of the graphed function

Illusion [34]

Answer:

Correct choice is A

Step-by-step explanation:

The range of the function are all possible values which variable y can take.

From the given diagram you can see that the variable x changes from -4 to the 9. So the domain of the function is $-4\le x\le 9.$

Also the variable y takes its values from -4 to 8. Thus, the range is $-4\le y\le 8.$

Factor 1.21a^6+22a^3+100

Monica [59]

Answer:

$\frac{1}{100} (11 {a}^{3} + 100)(11 {a}^{3} + 100)$

Step-by-step explanation:

$1.21 {a}^{6} + 22 {a}^{3} + 100 \\ = 1.21 {a}^{6} + 11 {a}^{3} + 11 {a}^{3}+ 100 \\ = 11 {a}^{3} (0.11 {a}^{3} + 1) + 100(0.11 {a}^{3} + 1) \\ = (0.11 {a}^{3} + 1) (11 {a}^{3} + 100) \\ = ( \frac{11}{100} {a}^{3} + 1) (11 {a}^{3} + 100) \\ = ( \frac{11{a}^{3} + 100}{100} ) (11 {a}^{3} + 100) \\ = \frac{1}{100} (11 {a}^{3} + 100)(11 {a}^{3} + 100) \\ are \: the \: required \: factors.$

The electric potential, VVV, in volts, between two metal plates a distance of ddd millimeters from the left plate is given by th

LenKa [72]

V is the voltage or the potential difference between the plates, usually expressed in volts.

Infinite parallel plates have a uniform electric field between them.

So V = 245 (V/m) * 0.0037 (m) = 0.9065 volts
