Answer:

It is the graph of y=2x translated 4 units downward

Step-by-step explanation:

Given

[tex]y = 2x[/tex] to [tex]y' = 2x - 4[/tex]

Required

We have:

[tex]y = 2x[/tex]

Subtract 4 from both sides [In other words, shift downward by 4 units]

[tex]y - 4 = 2x - 4[/tex]

This implies that:

[tex]y' = y -4[/tex]

Substitute [tex]y = 2x[/tex]

[tex]y' = 2x -4[/tex]

Answer:

It is the graph of y = 2x translated 4 units downward.

It is the graph of y = 2x translated 2 units to the right.

Step-by-step explanation:

Recall that f(x) − k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x − 4 translates the function y = 2x down 4 units. But 2x − 4 is also equal to 2(x − 2), so y = 2x − 4 also describes a translation to the right by 2 units.

Answer:

1014 cm²

Step-by-step explanation:

We are to find the surface area of the cube

The formula for the surface area of a cube is given as

A = 6a²

Where a = side length

From the above diagram, side length = 13cm

The surface area = 6 × 13²

= 1014 cm²

Therefore, it would take 1014 cm² of paper to cover the gift

Answer:

78cm^2

Step-by-step explanation:

You'd want to separate the two shapes into a rectangle and triangle. So you'd have one rectangle with one side being 2 and the long side 12. (2 * 12 = 24). Then a triangle with a base of 9 and a height of 12. (9 * 12 = 108 / 2 = 54) Then you add both areas together to get 54 + 24 = 78.

Answer:

B: 78

Step-by-step explanation:

cut it in half into a rectangle and traingle

the rectangles area is 2x12=24

The area of the triangle is 9x12=108   108/2 = 54

then add the 2 areas to get B:78

Step-by-step explanation:

Using PEMDAS

1) [tex](4^2+3+2)[/tex]

= 16 + 3 + 2

= 21

2) [tex]7^2 + 3[/tex] * 21

Answer:

2.5 km

Step-by-step explanation:

15 minutes is

15 minutes * 1 hour/ 60 minutes = 1/4 hour

15 minutes = 1/4 of an hour

10 km/ hour * 1/4 hour = 10/4  km  = 2.5 km

Answer:

In total she ran 2.5km/h in 15 minuets.

Step-by-step explanation:

Since 15 minuets is a quarter of an hour you can divide the 10km/h by 4 to get 2.5km/h.

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)

The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.

A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.

Given:

The coordinate of the graph is shown in figure  (2, 0),

As we can see from the graph, the slope: f' (2) is negative (Downwards)

Again, from the graph

f(2) = 0

Thus, the curve concave upward: f'' (2) is positive (upward)

f' (2)<0

f (2)=0

0 < f'' (2)

f' (2) < 0 < f'' (2)

Therefore, f' (2) < 0 < f'' (2) is true in the given graph.
