Lera25 [3.4K]

Answer:

(36π -72) cm²

Step-by-step explanation:

The area of a segment that subtends arc α (in radians) is given by ...

A = (1/2)r²·(α - sin(α))

Here, you have r = 12 cm and α = π/2 radians, so the area of the segment is ...

A = (1/2)(12 cm)²·(π/2 -1) = (36π -72) cm²

Find x<br> A. 22√2<br> B. 22<br> C. 11√3/3<br> D. 11√3

mel-nik [20]

Answer

$22\sqrt{2}$

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

$sin(45)=\frac{11}{Y} \\$ , Because sin(x)= op/hip

$cos(60)=\frac{Y}{x}$ , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

$Y=\frac{11}{sin(45)} \\Y=cos(60)*x$

we equal Y and solve

$\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\$

Then we rationalize

$x=22\sqrt{2}$

Hope you like it!

If a rock falls from a height of 40 meters on Earth, the height H (in meters) after x seconds is approximately

Julli [10]

Once the rock hits the ground, we know that its height will be equal to 0m
because of this, we can replace H(x) with 0
$40 - 4.9 {x}^{2} = 0$
now all we have to do is get x by itself
so..
$4.9 {x}^{2} = 40$
then
${x}^{2} = 40 \div 4.9$
${x}^{2} = 8.1632...$
now take the square root of each side
$x = 2.857...$
2.857 seconds (rounded to the third decimal)

What is the value of r of the geometric series n=11.3(0.8)n-1

jeyben [28]

the value of r of the geometric series n=11.3(0.8)n-1

$an=11.3(0.8)^{n-1}$

General formula for nth term of any geometric series is $a_n=a_1(r)^{n-1}$

Here 'r' is the common ratio

a_1 is the first term of the series

Now we compare the given formula with general formula

Compare $an=11.3(0.8)^{n-1}$ with $a_n=a_1(r)^{n-1}$

The value of r= 0.8

Solve for h please and thank you

KonstantinChe [14]

Answer:

35° (I may be wrong)

Step-by-step explanation:

An isosceles triangle has an interior angle sum of 180° (like all triangles).

So...

180°-40°= 140°

And because we know that isoceles triangles and two congruent sides, we just have to divide 140° by 2.

140°÷2=70°

But the picture says 2h and h is a side so...

70°÷2=35°
