Step-by-step explanation:
[tex] \frac{ { \cos}^{2} \theta}{1 - \sin \theta} \\ \\ = \frac{ { \cos}^{2} \theta}{(1 - \sin \theta)} \times \frac{(1 + \sin \theta)}{(1 + \sin \theta)} \\ \\ = \frac{{ \cos}^{2} \theta(1 + { \sin} \theta)}{(1 - { \sin}^{2} \theta)} \\ \\ = \frac{{ \cancel{ \cos}^{2} \theta}(1 + { \sin} \theta)}{ \cancel{{ \cos}^{2} \theta}} \\ \\ = 1 + { \sin} \theta[/tex]

Perimeter of triangle= sum of all sides of triangle
= 6+6+y
= 12+y
Answer:
Step-by-step explanation:
Perimeter is the length of any closed figure. So for a triangle, the Perimeter is equal to P = a + b + c.
You are told that the triangle is isosceles which means it has 2 equal. You are to presume that the third side is not equal to the other 2.
a= 6
b = 6
c = y
Perimeter = a + b + y
Perimeter = 6 + 6 + y
Perimeter = 12 + y

Find the image of the given point
under the given translation.
P(-9, -2)
T(x, y) = (x + 6, y − 4)
P' = ([?], [])
Explanation:
The notation [tex]T(x, y) = (x+6, y-4)[/tex] tells us to add 6 to the x coordinate and subtract 4 from the y coordinate.
An equivalent notation would be to write [tex](x,y) \to (x+6, y-4)[/tex]
Point P has the x coordinate of -9. Adding on 6 gets us the new x coordinate of -9+6 = -3
It also has the y coordinate of -2. Subtract off 4 to get -2-4 = -6
So,
[tex](x,y) \to (x+6, y-4)\\\\(-9, -2) \to (-9+6, -2-4)\\\\(-9, -2) \to (-3, -6)[/tex]
Answer:
P' (- 3, - 6 )
Step-by-step explanation:
the translation
(x, y ) → (x + 6, y - 4 )
means add 6 to the x- coordinate and subtract 4 from the y- coordinate , so
P (- 9, - 2 ) → P' (- 9 + 6, - 2 - 4 ) → P' (- 3, - 6 )

Find the area of the semicircle. Round your answer to the nearest hundredth.
Answer:
452.39
Step-by-step explanation:
area of circle = [tex]\pi r^{2}[/tex]
area of semi circle is [tex]\pi r^{2}[/tex] divided by 2 (because a semi circle is half of a circle)
diameter = 2 x radius, and radius = half of diameter
so
radius = 24 / 2 = 12
[tex]12^{2}[/tex] x π = 452.389342
to nearest hundredth = 452.39

Answer:
266.19 in²
Step-by-step explanation:
[tex]\sf Area\:of\:a\:circle=\pi r^2[/tex] (where r is the radius of the circle)
As a semicircle is half a circle
[tex]\implies \sf Area\:of\:a\:semicircle=\dfrac12\pi r^2[/tex]
From inspection of the diagram, we can see that the diameter (the widest part of a circle) is 24 in.
[tex]\sf Radius\:of\:a\:circle\:(r)=\dfrac12diameter[/tex]
Therefore, the radius of the circle = 24 ÷ 2 = 12 in
Substitute r = 12 into the equation for the area of a semicircle:
[tex]\begin{aligned}\implies \sf Area\:of\:a\:semicircle & =\dfrac12\pi 12^2\\ & =\dfrac12 \cdot \pi \cdot 144\\ & = 72\pi \\ & = 266.19\: \sf in^2 \:(nearest\:hundredth)\end{aligned}[/tex]

What is Greatest common factors?The highest number that divides exactly into two more numbers, is called Greatest common factors.
Given that;
The expressions are,
⇒ 48ab²
⇒ 32a²b
Now,
GCD of 32, 48 = 16
And, GCD of (ab²) and (a²b) = ab
Thus, The greatest common factors of the expressions 48ab² and 32a²b are,
⇒ 16 ab

The parabola in the image has its focus at (4,3).Its directrix is the line y=1.The point (8,6) is on the parabola.
The statements that are true for this parabola are:
C. The point (8, 6) is the same distance from the point (4, 3) as it is from the line y = 1.
Option D.
Given the following data:
Vertex (h, k) = (4, 3).Point (x, y) = (8, 6).How to determine the equation of the directrix?Mathematically, the standard equation of the directrix line for a parabola is given by: y = a(x - h)² + 2.
Next, we would determine the distance where point (8, 6) lie on the parabola as follows:
y = a(x - h)² + 2
6 = a(8 - 4)² + 2
6 = a(4)² + 2
6 = 16a + 2
16a = 6 - 2
16a = 4
a = 4/16
a = 1/4.
Therefore, the parabolic equation becomes:
y = 1/4(x - 4)² + 2
When x = 2, we have:
y = 1/4(2 - 4)² + 2
y = 1/4(-2)² + 2
y = 1/4(4) + 2
y = 1 + 2
y = 3.
In conlusion, the statements that are true for this parabola in the image above include:
The point (8, 6) is the same distance from the point (4, 3) as it is from line (y = 1).The point (2, 3) is on the parabola.Read more on directrix here: https://brainly.com/question/2346582

Answer:
2√30
Step-by-step explanation:
Since we have a right triangle, we first need to find the base of the big triangle, which is also the hypo of the smaller triangle.
We apply A²+B²=C²
We plug values in that we have
15²+B²=19²
Simplify
B²=136
B=√136=√2x2x2x2x17=4√17
Now that we have the hypo for the small triangle we apply the same formula to get X
4²+X²=√136
16+X²=136
X²=120
X=√120=√2x2x2x3x5=2√30
Answer:
11.0 mm (3sf)
Step-by-step explanation:
Let length of hypotenuse of smaller triangle be H mm. (this is referring to the only unlabelled length in the picture)
by the Pythagorean theorem (larger triangle),
19² = 15² + H²
H² = 361 - 225
H² = 136
by the Pythagorean theorem (smaller triangle),
H² = 4² + x²
136 = 16 + x²
x² = 120
x = 11.0 mm (3sf)
