Answer:

0.6 m

Step-by-step explanation:

From the question,

The largest table top that could be cut from a rectangular piece of wood,

will have a diameter equal to the smallest dimension of the rectangular piece of wood. As shown in the diagram attached.

 If it is cut along the biggest dimension of the rectangular piece of wood, the tabletop won't be circular, rather, it will form a sphere. So the only way the tabletop can be cut out of the rectangular piece of wood to make it circular is to cut it along the smaller dimension of the rectangular piece of wood.

Given, the dimensions of the rectangular piece of wood as 1.2 m by 1.8 m.

Then the diameter of the table top formed = 1.2 m.

but,

radius = diameter/2

radius = 1.2/2

radius = 0.6 m

Hence, the radius of the largest tabletop that could be cut out of the rectangular piece of wood is 0.6 m

The given graph of g(x) is translated 4 units to left, so the function is g(x)=(x+4)². Therefore, option D is the correct answer.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

From the graph, f(x)=x².

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Up

Vertex: (0,0)

Focus: (0,1/4)

Axis of Symmetry: x=0

Directrix: y= -1/4

In the graph we can graph of g(x) is translated 4 units to left, so the function is g(x)=(x+4)²

Therefore, option D is the correct answer.

Answer: B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Let's look at A.

A simplified = 7x - 6

Let's look at B

B simplified = 2 + 7x

Let's look at C

C simplified = -6 + 7x OR 7x - 6

Let's look at D, lastly.

D simplified = 7x - 6

In conclusion, we can see that 7x - 6 is the answer we need to arrive at  to have equivalent expressions. Only B does not have that answer, so B is the answer.

The correct choice for the missing reason is,

⇒ Factor

An algebraic equation with the second degree of the variable is called an Quadratic equation.

We have to given that;

The steps for deriving the Quadratic Formula are shown.

Now, From fifth step;

⇒ x² + bx/a + b²/4a² + ----- - c/a + b² / 4a²

Hence, By factor we get;

⇒ (x + b/2a) (x + b/2a) +   ------ - c/a + b² / 4a²

So, The correct choice for the missing reason is,

⇒ Factor

Answer:

About 4.5 hours, you can say 5 hours

Step-by-step explanation

You can solve this by constructing a linear equation, which would turn out like this, 25x+60=172.50. How I got this is that it says his charge is 25 per hour, that is basically multiplication by an unknown number, so put that as a variable. Next it says he has a service fee of 60 dollars, this is what's called an initial fee. Now all we need to do is solve for x, which turns into 4.5. I don't know if they ask to round your answer or something, I hope this is right.
