Which one does it simplify to? please
Answer:
[tex]1 + { \sin} \theta[/tex]
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]
Let's see
[tex]\\ \rm\Rrightarrow \dfrac{cos^2\theta}{1-sin\theta}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{1-sin^2\theta}{1-sin\theta}[/tex]
(a+b)(a-b)=a²-b²[tex]\\ \rm\Rrightarrow \dfrac{(1-sin\theta)(1+sin\theta)}{1-sin\theta}[/tex][/tex]
[tex]\\ \rm\Rrightarrow 1+sin\theta[/tex]

Please help me with this ill give you brainlist answer
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)

Solve the System of these Equations
Answer:
y=-9/2, x=7
Step-by-step explanation:
You can solve this via substitution. First solve for x in terms of y in one of the equations given. Lets use the first one:
25+4y=x
Now plug 25+4y in for x in the second equation
3(25+4y)-2y=30
75+12y-2y=30
75+10y=30
10y=-45
y=-9/2
Plug this into the first equation:
25-x=-4(-9/2)
25-x=18
x=7

The perimeter of a triangle is 42 yards. The first side is 5 yards shorter than the
second side, and the third side is 2 yards shorter than the first side. What is the length
of each side?
Answer: Is your question "What is the length of each side?"
Let x = the length of the second side
Let x - 5 = the length of the first side
Let (x - 5) - 2 = the length of the third side
P = a + b + c
x + x - 5 + x - 7 = 42
3x - 12 = 42
3x = 54
x = 18 yards
x - 5 = 13 yards
x - 7 = 11 yards

in a binomial experiemnt the probability of success is 0.16. what is the probability of two successes in seven trials
Answer:
0.2248307402
Step-by-step explanation:
Let 'success', p = 0.16,
and 'failure', q = 1 - 0.16 = 0.84
and the number of trials, n = 7
r = 2
[tex]P(X = r) = \binom{n}{r} {p}^{r} {q}^{n - r} \\ P(X = 2) = \binom{7}{2} {(0.16)}^{2} {0.84}^{5 - 2} \\ = 0.2248307402[/tex]
Find the image of the given point

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 )
Determine the equation of the line with the following characteristics.
Slope=3, passing through (-1, 10)
Answer:
y = 3x + 13
Step-by-step explanation:
The equation of a line is also known as slope-intercept form.
Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept.
To put an equation in slope-intercept form, we need the slop and the y-intercept.
In this case, we already have the slope which is 3.
So far, we have y = 3x + b
Now, we need to find the y-intercept.
Since you already have a point, we can plug in the x and y values from the point, into the equation.
10 = 3(-1) + b
Now, we can solve for b.
10 = -3 + b
Add three on both sides so it becomes:
13 = b
13 is the y-intercept
y = 3x + 13

The axis of symmetry of the quadratic equation y = 2x^2 + 3 is x = 0
How to determine the axis of symmetry?The equation is given as:
y = 2x^2 + 3
Differentiate the above equation with respect to x
y' = 4x + 0
This gives
y' = 4x
Set the equation to 0
4x = 0
Divide both sides by 4
x = 0
Hence, the axis of symmetry is x = 0
