Answer:

  (d)  5a²

Step-by-step explanation:

  \displaystyle\sqrt[3]{125a^6}=\sqrt[3]{5^3a^6}=\sqrt[3]{(5a^2)^3}=\boxed{5a^2}

__

The applicable rules of exponents are ...

  (a^b)^c = a^(bc)

  ∛a = a^(1/3)

Write the slope intercept ​
mrs_skeptik [129]

Answer:

b = 4,

m = 4/3,

y = 4x/3 + 4

Step-by-step explanation:

We can see the line intercepts the x-axis in (-3,0) and the y-axis in (0,4). So, using the fact that the line equation in the slope-intercept form is:

y = mx+b

We can substitute the points we know:

→ (0,4):

y = mx+b\\\\4 = m\cdot0+b\\\\4 = 0+b\\\\\boxed{b=4}

→ (-3,0):

y = mx+b\\\\0 = -3m + 4\\\\3m = 4\\\\\boxed{m = \dfrac{4}{3}}

So, the line equation in form requested is:

\boxed{y=\dfrac{4}{3}x+4}

grandymaker [24]

Answer:

A

Step-by-step explanation:

We can break down what each term represents in the equation

60 is the constant. This is the base price that is paid regardless of workers and hours needed

Then there is 12nh. 12 represents the cost per hour for one worker. If the job takes only one hour, then it is 12 dollars per worker. Similarly, if the job only takes one person, then it is 12 dollars for each hour.

The most accurate answer is A

Please help how do i find the area of the shape?
Orlov [11]

Answer:

Do not listen to the other answer! Here is how you solve that.

Step-by-step explanation:

For the semicircle, here is the formula for area: A= \frac{1}{2}(\pi r^2)

For the triangle, here is the formula for area:A=\frac{1}{2}(bh)

Then, add.

So,

Triangle:

A=\frac{1}{2}(9*12)

A=54

Semicircle:

A=\frac{1}{2}(\pi 6^2)

A=18\pi

Your answer is Area = 54 + 18\pi
