Somebody helpl pls what is the approximate area

Serga [27]

Answer:

20.36

Step-by-step explanation:

The area of the whole circle is pi*3.6^2 = 40.715 (rounded). However, the shaded portion is only half of the circle, since the arc is 180 degrees, so we divide this by 2 to get about 20.36.

Which of the following statements is true

kolbaska11 [484]

Answer:

D. This quadratic equation two complex solutions.

Step-by-step explanation:

$5x^2 +6x +2= 0\\$

Equating it with

$ax^2 +bx +c= 0\\$

a = 5, b = 6, c = 2

$b^2 -4ac\\= 6^2 - 4\times 5\times 2\\= 36-40\\b^2 -4ac= - 4\\$

$\because b^2 -4ac$ is negative.

Therefore, this quadratic equation two complex solutions.

Question 1 (1 point)

insens350 [35]

Answer:

1. q = p - mn

2. c = -6

3. 10

Step-by-step explanation:

$mn=p-q\\\textsf{add q to both sides}\implies mn + q = p\\\textsf{subtract mn from both sides}\implies q = p-mn$

$5c+23=c-1\\\textsf{subtract 23 from both sides}\implies5c=c-24\\\textsf{subtract c from both sides}\implies4c=-24\\\textsf{divide both sides by 4}\implies c=-6$

$4f^2-g\\\implies 4(2)^2-3=13\\\\3f^2-3g\\\implies 3(2)^2-(3 \times3)=3\\\\13-3=10$

Which of the following is a geometric sequence?

anastassius [24]

The key thing to look for to determine whether a sequence is geometric is to see whether the ratio between consecutive terms - the number I would multiply one term by to get the next - is constant.

By inspection, we see that the fourth answer choice satisfies that, as $\frac{81}{27}=\frac{27}{9}=\frac{9}{3}=\frac{3}{1}=3.$ Why not the first? We have $2=\frac{12}{6}\ne\frac{6}{2}=3.$

The third choice is not a geometric sequence, but rather an arithmetic sequence, where the difference between consecutive terms is constant. Just to make sure that it isn't geometric, we compute $\frac{14}{9}\ne\frac{9}{4}.$

The second sequence is not geometric (although it does eventually converge to 1, but not its corresponding series), as $\frac{4}{3}=\frac{2/3}{1/2}\ne\frac{3/4}{2/3}=\frac{9}{8}.$

The area of a rectangle is 756 square centimeters. The of the long the width is 7:3. Find the length and the width

Fed [463]

Answer:

18 cm and 42 cm

Step-by-step explanation:

a = wl

7w = 3l, then l = 7/3w

756 = w(7/3w)

756 = 7/3w²

w² = 324

w = 18

l = 42
