find the area of the shaded figure​

Answer:

cos(A) = 12/13

Step-by-step explanation:

There are several ways to remember trigonometric functions, but my personal favorite is:

SOH - CAH - TOA

Where Sin(angle) = Opposite/Hypotenuse

Cos(angle) = Adjacent/Hypotenuse

and Tan(angle) = Opposite/Adjacent

The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.

The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).

The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.

The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

Answer:

Since it is the case of independent the answer will be 6/22

Answer:

530.66 m²

Step-by-step explanation:

Area of circle= π×radius²

So the radius is 26/2= 13

13×13=169

So 3.14×169 would be the area

3.14×169= 530.66

(And if you have to round to the nearest tenth it would be 530.7)

Answer:

10.82

Step-by-step explanation:

6^2+9^2=x

36+81=117

Square root of 117 is 10.82

The value of the given side x  in the given circle is 10.82.

We have given that,

If necessary, round your answer to the nearest tenth. O is the center of the circle. The figure is not drawn to scale.

[tex]side^2+side^2=hypotenous^2[/tex]

6^2+9^2=x^2

36+81=117

117=x^2

taking square root on both sides.

The Square root of 117 is 10.82.

Therefore the square root of the 117 is 10.82.

Step-by-step explanation: Since the values of A and B are both negative (because they are below 0), adding them together will also make the sum negative.

Answer:

The selection of r objects out of n is done in

many ways.

The total number of selections 10 that we can make from 6+7=13 students is  

thus, the sample space of the experiment is 286

A.  

"The probability that a randomly chosen team includes all 6 girls in the class."

total number of group of 10 which include all girls is C(7, 4), because the girls are fixed, and the remaining 4 is to be completed from the 7 boys, which can be done in C(7, 4) many ways.

P(all 6 girls chosen)=35/286=0.12

B.

"The probability that a randomly chosen team has 3 girls and 7 boys."

with the same logic as in A, the number of groups were all 7 boys are in, is  

so the probability is 20/286=0.07

C.

"The probability that a randomly chosen team has either 4 or 6 boys."

case 1: the team has 4 boys and 6 girls

this was already calculated in part A, it is 0.12.

case 2, the team has 6 boys and 4 girls.

there C(7, 6)*C(6, 4) ,many ways of doing this, because any selection of the boys which can be done in C(7, 6) ways, can be combined with any selection of the girls.  

the probability is 105/286=0.367

since  case 1 and case 2 are disjoint, that is either one or the other happen, then we add the probabilities:

0.12+0.367=0.487 (approximately = 0.49)

D.

"The probability that a randomly chosen team has 5 girls and 5 boys."

selecting 5 boys and 5 girls can be done in  

many ways,

so the probability is 126/286=0.44

Answer:

true answer I'm search in Goole

The root of the quadratic equation x = -3/4[tex]\pm[/tex] √-31/ 4.

Suppose that we've a function y = f(x) such that f(x) is quadratic.

When y = 0, then the values of x for which f(x) = 0 is called solution of quadratic equation f(x) = 0

These solution gives values of x, and when we plot x and f(x), we'd see that the graph intersects the x-axis at its solution points.

Then its roots are given as

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Given; 2x^2 + 3x + 5 = 0

We know that a=2, b=3, c=5

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]x = \dfrac{-3\pm \sqrt{3^2 - 4(2) ( 5)}}{2(2)}\\\\\\x = \dfrac{-3\pm \sqrt{9 - 40}}{4}\\\\\\x = \dfrac{-3\pm \sqrt{-31}}{4}\\\\\\x = \dfrac{-3}{4}\pm \dfrac {\sqrt{-31}}{4}[/tex]
