Answer:

None of the Above

Step-by-step explanation:

As it is given that

cosФ= 3/2

and Ф lies in quadrant 4

Now in quadrant 4 we know that by the rules of trigonometry that

cos Ф is positive in 4th quadrant also in 4th quadrant

and sinФ is negative in 4th quadrant

also we know that by simple rules of trigonometry in a right angled triangle

cos Ф=[tex]\frac{Base}{Hypotenuse}[/tex] =[tex]\frac{3}{2}[/tex]

now from the law of trigonometry

cos²Ф+sin²Ф=1

From this we derive the value of sinФ

solving the equation

sin²Ф=1-cos²Ф

Putting in the values of cos Ф

sin²Ф=1-[tex](\frac{3}{2})^{2}[/tex]

sin²Ф=1-[tex](\frac{9}{4})[/tex]

solving the fraction

sin²Ф=[tex](\frac{4-9}{4})[/tex]

sin²Ф=[tex](\frac{-5}{4})[/tex]

so taking square root of both sides

[tex]\sqrt{sin^{2}\alpha}=\sqrt{\frac{-5}{4} }[/tex]

here

[tex]\alpha[/tex]=Ф

so it becomes

sin Ф=[tex]\frac{\sqrt{-5} }{2}[/tex]

as we know that in imaginary numbers

[tex]\sqrt{-1}[/tex] = ι

so the given becomes

sin Ф=[tex]\frac{{-5ι} }{2}[/tex]

Which is the value of sin Ф

And in the given values we can see that it is none of the values

Also seeing the question we can see that the question is absurd because

cos Ф= base / hypotenuse

in our question we can see that base =3 and hypotenuse = 2

but in real geometry this is the rule that hypotenuse can never be smaller then base either it is equal to base or greater then base

the formula for finding value of finding hypotenuse is

hypotenuse ² = base ² + perp ²

so this formula shows that if perp is 0 then hypotenuse will be equal to base

in other cases it would be greater then base

Answer:

- 1/ 2

Step-by-step explanation

-1\ 2

Use the Pythagorean identity, sin2Θ + cos2Θ = 1 to get sinΘ = ±1 - cos2Θ, then solve for sinΘ.

[tex]QR=\sqrt{68^2-60^2}\\QR=\sqrt{4624-3600}\\QR=\sqrt{1024}\\QR=32\\\\sinS=\frac{32}{68}\\sinS=\frac{8}{17}[/tex]

For this case, we have that by definition:

Be a rectangular triangle and an "x" angle.

[tex]Sine (x) = \frac {CO} {H}[/tex]

CO is the leg opposite the angle and H the hypotenuse

We want to find the Sine (S) according to the figure shown:

[tex]Sine {S} = \frac {QR} {68}[/tex]

We do not have the opposite leg, we must apply the Pythagorean theorem, which states:

[tex]H = \sqrt {(CO) ^ 2 + (CA) ^ 2}[/tex]

Where:

H: Hypotenuse

CO: Opposite leg

CA: Adjacent leg

In this case, we must find CO:

[tex]CO = \sqrt {H ^ 2- (CA) ^ 2}[/tex]

Where:

[tex]H = 68\\CA = 60[/tex]

Substituting:

[tex]CO = \sqrt {68 ^ 2-60 ^ 2}\\CO = \sqrt {4624-3600}\\CO = \sqrt {1024}\\CO = 32[/tex]

So, we have:

[tex]Sine (S) = \frac {32} {68}[/tex]

Answer:

[tex]Sine (S) = \frac {32} {68}[/tex]

[tex]Sine (S) = \frac {8} {17}[/tex]

Answer:

area = 6m + 51 feet²

Step-by-step explanation:

[tex]\frac{7}{9} +\frac{2}{9} = hyp^{2}[/tex]

1 = hyp²

1 = hyp

sin = [tex]\frac{opp}{hyp} =\frac{\sqrt{2}}{3}[/tex]

cos = [tex]\frac{adj}{hyp} =\frac{\sqrt{7}}{3}[/tex]

tan = [tex]\frac{opp}{adj} =\frac{\sqrt{2}}{sqrt\{7}=\frac{\sqrt{14}}{7}}[/tex]

Answer: (2, 9)

Step-by-step explanation:

3x - 8y = -66   →   2(3x - 8y = -66)   →   6x - 16y = -132

2x - 7y = -59   →  -3(2x - 7y = -59)   →  -6x + 21y = 177

                                                                        5y = 45

                                                                          y  = 9

2x - 7y = -59

2x - 7(9) = -59

2x - 63 = -59

2x         = 4

x          = 2

Answer:

Let x represents the ounces of first spice.

From the given statements, you draw a table as shown below:

                           ounces of spice         Percentage           ounces of salt

First spice                 x                              3%                            0.03x

Second spice           175                            6%                          175(0.06)

Final  mixture          x+ 175                         5%                        (x+175)(0.05)

Now, to solve for x;

Final spice = First spice + second spice

[tex]0.03x+175(0.06) = (x+175)(0.05)[/tex]

[tex]0.03x + 10.5 = 0.05x + 8.75[/tex]

Subtract 10.5 on both sides we have;

[tex]0.03x + 10.5 -10.5= 0.05x + 8.75-10.5[/tex]

Simplify:

[tex]0.03x= 0.05x -1.75[/tex]

Subtract 0.05x on both sides;

[tex]0.03x - 0.05x= 0.05x -1.75-0.05x[/tex]

Simplify:

[tex]-0.02x= -1.75[/tex]

Divide both sides by -0.02, we get;

x = 87.5 ounces

Therefore, 87.5 ounces of spices i.e 3% salt should be added to 175 ounces of a spice that is 6% salt in order to make a spice that is 5% salt

Answer:

16

Step-by-step explanation:

16

Answer:

16

18 minus 14 is 4. 4 times 4 is 16.

A scale factor of 1/2 makes the triangle half the size of the original.

The original is 4 units tall, so 1/2 scale makes the new one 2 units tall.

It is 6 units long, so 1/2 would be 3 units long.

Now since the scale factor is centered at (-1,3) fine the midpoint between The top left corner of the triangle and the center point:

Midpoint ( -1-5/2 , 3+7/2)

Midpoint = (-6/2 , 10/2)

Midpoint = -3,5

This is where the top left corner of the scaled triangle would be.

Answer:

∠NET = 63°

Step-by-step explanation:

We are given a figure with a circle A and a line ET which is tangent to the circle at the point T. Also, the measure of the angle TNG is given to be 27° and we are to find the measure of angle NET.

If we recall the point of tangency, we will remember that the point where a tangent touches the radius of a circle is always a right angle.

That makes the angle NTE to be 90°.

Putting the sum of these angles equal to 180 to get:

90 + 27 + ∠NET = 180

∠NET = 180 - 90 - 27

∠NET = 63°

[tex]4csc(2x) = 2csc^2(x) tan(x)[/tex]

We start with Left hand side

We know that csc(x) = 1/ sin(x)

So csc(2x) is replaced by 1/sin(2x)

[tex]4 \frac{1}{sin(2x)}[/tex]

Also we use identity

sin(2x) = 2 sin(x) cos(x)

[tex]4 \frac{1}{2sin(x)cos(x)}[/tex]

4 divide by 2 is 2

Now we multiply top and bottom by sin(x) because we need tan(x) in our answer

[tex]2\frac{1*sin(x)}{sin(x)cos(x)*sin(x)}[/tex]

[tex]2\frac{sin(x)}{sin^2(x)cos(x)}[/tex]

[tex]2\frac{1}{sin^2(x)} \frac{sin(x)}{cos(x)}[/tex]

We know that sinx/ cosx = tan(x)

Also  1/ sin(x)= csc(x)

so it becomes 2csc^2(x) tan(x) , Right hand side

Answer: C) 1

===========================================================

One way is to graph the function f(x) = ln(x)/(x-1) and you'll see the curve slowly approach y = 1 when x approaches 1 from either side. Check out the attached image labeled "figure 1" for this graph.

---------

You can use a table to see this in action. See figure 2 (attached below as well).

-----------

Another alternative is to use L'Hospital's rule. This is because we get the indeterminate form 0/0 after plugging x = 1 into the original function.

if y = ln(x), then dy/dx = 1/x

If y = x-1, then dy/dx = 1

So f(x) = ln(x)/(x-1) becomes (1/x)/1 = 1/x

If you plug in x = 1, you get 1/x = 1/1 = 1.

Regardless of which method you use, the limiting value is 1

Answer: sqrt(19)/10

Step-by-step explanation:

sinx=0.9

x=arcsin(0.9)

Insert x for cos(x):

cos(arcsin(0.9)=

Use identify [tex]cos(arcsin(x))=\sqrt{1-x^{2} }[/tex], so

[tex]\sqrt{1-(\frac{9}{10})^{2}} =\sqrt{\frac{19}{100} } =\frac{\sqrt{19}}{10}[/tex]

Sorry if this is confusing.

Final answer:

To find cos X given sin X = 0.9, use the Pythagorean identity, solve for cos2 X, take the square root, and round to the nearest thousandth to get cos X ≈ 0.436.

Explanation:

To calculate the value of cos X when sin X= 0.9, we can use the Pythagorean identity which states that sin2X + cos2X = 1. First, square the sine value: (sin X)2 = 0.92 = 0.81. Then, we subtract this value from 1 to find (cos X)2: 1 - 0.81 = 0.19. Finally, we take the square root of 0.19 to find the value of cos X. Since sin X is positive and assuming X is an angle in the first quadrant, cos X will also be positive. So, cos X = √0.19 ≈ 0.436.

Therefore, the value of cos X, rounded to the nearest thousandth, is 0.436.

Answer:

Use point slope form, by finding the slope between two of the points given on the line you can then input it with one of the points into the formula. Then simplify to convert to slope-intercept form. You can then graph it easily. After which, you can convert to standard form by getting the variables to one side. Be sure in standard form to clear negatives x may have or any fractions x or y may have through multiplication.

Step-by-step explanation:

To write an equation for linear equations, we use one of three forms: standard, slope intercept, and point slope. Slope intercept and point slope are the most common. After we choose our form, we need to find the information required for that form. Point slope is easiest since it requires the slope/rate of change and any point on the line.

Point slope:[tex]y-y_1=m(x-x_1)[/tex]

We must find the slope using the slope formula.

Slope:[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We substitute [tex]x_1=-3\\y_1=1[/tex] and [tex]x_2=3\\y_2=5[/tex]

[tex]m=\frac{5-1}{3-(-3)}[/tex]

[tex]m=\frac{4}{3+3}=\frac{4}{6} =\frac{2}{3}[/tex]

We will substitute [tex]m=\frac{2}{3}[/tex] and [tex]x_1=-3\\y_1=1[/tex].

[tex]y-1=\frac{2}{3} (x-(-3))[/tex]

We can simplify to get slope intercept form:

[tex]y-1=\frac{2}{3} (x+3))[/tex]

[tex]y-1=\frac{2}{3}x+\frac{2}{3}(3)[/tex]

[tex]y-1=\frac{2}{3}x+2[/tex]

[tex]y-1+1=\frac{2}{3}x+2+1[/tex]

[tex]y=\frac{2}{3}x+3[/tex]

This is the slope intercept form. We can graph it by finding 3 on the y-axis. Plot a point there.  Then move up two units and to the right three units. Plot a point. Connect the points.

To convert to Standard Form, we will rearrange the equation with x and y on the same side.

[tex]y=\frac{2}{3}x+3[/tex]

[tex]-\frac{2}{3}x+y=\frac{2}{3}x-\frac{2}{3}x+3[/tex]

[tex]-\frac{2}{3}x+y=3[/tex]

[tex]-3(-\frac{2}{3}x+y=3)[/tex]

[tex] 2x-3y=-9[/tex]

This is the standard form.
