We calculate for the circumferences of Earth and moon by using the equation,
                                C = 2πr
For Earth,
                                C = 2π(6371 km) = 40030.2 km
For Moon,
                               C = 2π(1737.5 km) = 10917.0 km
The difference between the two circumferences is 29113.2 km approximately.

To help explain how you get A for the answer:
work backwards
5(3a²+11a-4)
multiply everything by 5
5×3a²=15a²
5×11a=55a
5×-4=-20
15a²+55a-20

If f(x) =2x-6 then f(1)=​
marin [14]

Answer:

f(1) = -4

Step-by-step explanation:

Given that,

f(x) = 2x-6

We need to find the value of f(1).

Put x = 1 in the above expression.

f(1) = 2(1)-6

= 2-6

= -4

So, the value of f(1) is equal to -4.

A rectangle is transformed according to the rule R0, 90º. The image of the rectangle has vertices located at R'(–4, 4), S'(–4, 1
zalisa [80]
We are said that a rectangle has been transformed into the one indicated in Figure 1 according to this rule:

R_0, \ 90^{\circ}

We know that the center of rotation is origin and two rules are applied to rotate a point 90 degrees, namely:

1. Clockwise

In this case, the rule to transform a point is:

(x,y) \rightarrow (y,-x)

This rule was already applied to form the image, so all we need to do is to reverse the answer using this formula, therefore:

For \ Q(-3,4): \\ \\ (y,-x)=(-3,4) \\ \\ \therefore y=-3 \ and \ -x=4 \therefore x=-4 \\ \\ Thus, \ the \ point \ is: \\ \\ \boxed{Q(-4,-3)}

2. Counterc
lockwise

Applying the same previous concept but with the new rules for this case:

(x,y) \rightarrow (-y,x)

By reversing the answer, we have:

For \ Q(-3,4): \\ \\ (-y,x)=(-3,4) \\ \\ \therefore -y=-3 \therefore y=3 \ and \ x=4 \\ \\ Thus, \ the \ point \ is: \\ \\ \boxed{Q(4,3)}
