Step-by-step explanation:

first find out the area of sector ECF

π(10)² × 40°/360°

=100π×1/9

=100π/9 m²

now find the area of sector DCG

π(2)² × 40°/360°

=4π/9 m²*

so the area of the shaded region would be the big sector minus the small sector

100π/9 - 4π/9

=96π/9

=33.5 m² (3sig.fig.)

*Note that 4π/9 DOES NOT equal to 2π/3

4/9 DOES NOT EQUAL TO 2/3

So we know that x = 90º because it is a right angle. And angle B also has to be 47º because it is a reflection of angle C. And all the angles of any triangle are equal to 180º, so if we do 180-(90+47)=43. So now we know that y=43º and x=90º Your welcome, please give me brainlest.

In how many distinct ways can the digits in the number 7,511,111 be arranged?

Answers

The number of distinct ways in which the digits of the number 7,511,111 can be arranged is of:

42.

How to obtain the number of arrangements?

The total number of arrangements of n elements is given by the factorial of n, as follows:

A(n) = n!

When a few of the elements repeat, the number of arrangements with repetition is given by the equation presented as follows, also involving factorials.

[tex]A_n^{n_1, n_2, \cdots n_n} = \frac{n!}{n_1!n_2! \cdots n_n!}[/tex]

In which [tex]n_1, n_2, \cdots n_n[/tex] is the number of times that each element repeats.

For the number 7,511,111, we have that:

There are seven digits.The digit one repeats five times.

Hence the number of distinct arrangements of the number 7,511,111 is given as follows:

7!/5! = 7 x 6 = 42 distinct arrangements.

The graph of the function is positive on (2, 4).
The graph of the function is negative on (4, infinity).
The graph of the function is positive on (negative infinity, –7).
The graph of the function is negative on (–7, –1).

Answers

Answer:

C. The graph of the function is positive on (negative infinity, –7).

Step-by-step explanation:

With given conditions we can state:

The graph is positive between (-∞, -7)∪(-7, -1)∪(4, +∞), since it touches -7 and is positive either side of it.The graph is negative between (-1, 2) and (2, 4), since it touches 2 and is negative either side of it.Overall shape is U as leading coefficient is positive and is of even degree.

Comparing with the answer choices, correct choice is C.
