Answer:

-3/5

Step-by-step explanation:

Answer:

[tex]-\frac{3}{5}[/tex]

Step-by-step explanation:

Remember that the tangent trigonometric ratio is the opposite side of right triangle divided by the adjacent side:

[tex]tan(\alpha )=\frac{opposite-side}{adjacent-side}[/tex]

[tex]tan(\alpha )=-\frac{4}{3}[/tex]

Comparing the equations we can infer that:

opposite side = 4

adjacent side = 3

Now we can use Pythagoras to find the hypotenuse of our right triangle:

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

[tex]hypotenuse^2=4^2+3^2[/tex]

[tex]hypotenuse^2=25[/tex]

[tex]hypotenuse=\sqrt{25}[/tex]

[tex]hypotenuse=5[/tex]

Remember that the cosine trigonometric ratio is the adjacent side divided by the hypotenuse; in other words:

[tex]cos(\alpha)=\frac{adjacent-side}{hypotenuse}[/tex]

We know that adjacent side = 3 and hypotenuse = 5.

Replacing values:

[tex]cos(\alpha )=\frac{3}{5}[/tex]

Now, remember that cosine means x and sine means y. In Quadrant 2 x is negative, which means that cosine is negative.

So, if [tex]tan(\alpha )=-\frac{4}{3}[/tex] in quadrant 2, then [tex]cos(\alpha )=-\frac{3}{5}[/tex]

Answer:

D, neither

Step-by-step explanation:

to determine whether a function is even, odd or neither, we need to know what it means

an even function is symmetric with respect to the y-axis

an odd function is symmetric with respect to the origin

to solve an equation to see if its even or odd, we would need to substitute x in the equation for -x.

in an even function when we substitute f(-x), it should be equal to to f(x)

in an odd function when we substitute f(-x), it should be equal to -f(x)

so lets test the function given to see if its even

f(x) = x³ + 4x

f(-x) = (-x)³ + 4(-x)

f(-x) = x³ - 4x

f(-x) = x³ - 4x ≠ f(x) = x³ + 4x

comparing this to the orignal function, we see that f(-x) = x³ - 4x is not even as we did not get the same output as the original function

now we should test to see if its odd. we have already seen what f(-x) is, now lets try -f(x) and compare it to f(-x) and f(x)

-f(x) = -(x³ + 4x) -->

-f(x) = -x³ - 4x ≠ f(-x) = x³ - 4x

f(-x) = x³ - 4x ≠ f(x) = x³ + 4x

comparing this to f(x) and f(-x), we see that it not odd as we did not get the same output

so the answer is D, neither even nor odd

Answer:

[tex]\sin\left(-180^o+\theta\right)=-\sin\left(\theta\right)[/tex]

Step-by-step explanation:

We need to find the value of [tex]\sin(-180^o+ \theta)[/tex]

So let's apply formula

[tex]\sin\left(A+B\right)=\sin\left(A\right)\cos\left(B\right)+\sin\left(B\right)\cos\left(A\right)[/tex]

[tex]\sin\left(-180^o+\theta\right)=\sin\left(-180^o\right)\cos\left(\theta\right)+\sin\left(\theta\right)\cos\left(-180^o\right)[/tex]

[tex]\sin\left(-180^o+\theta\right)=0\cdot\cos\left(\theta\right)+\sin\left(\theta\right)\cdot\left(-1\right)[/tex]

[tex]\sin\left(-180^o+\theta\right)=0-\sin\left(\theta\right)[/tex]

Final answer:

The missing length of the hypotenuse (c) in the right triangle with legs a=6 and b=8 is found using the Pythagorean theorem. By squaring both a and b, adding those squares together, and then taking the square root, we determine that c equals 10 units.

Explanation:

To find the missing length of the hypotenuse (c) of the right triangle when given the lengths of the other two sides (a and b), we can use the Pythagorean theorem. The theorem states that for a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). In mathematical terms, this is represented as a² + b² = c².

Given that side a is 6 and side b is 8, we can substitute these values into the theorem's formula:

Therefore, the length of the hypotenuse (c) is 10 units.

Please see the attached images below, to find more information about the graph

The correct answer is option

a) x ≥ -1 , x ≠ 6

Answer:

a) [tex]x\geq -1,x\neq 6[/tex]

Step-by-step explanation:

We have been given a function [tex]f(x)=\frac{\sqrt{x+1}}{(x+4)(x-6)}[/tex]. We are asked to find the domain of our given function.

We can see that our given function is a rational function and numerator of our given function is a square root.

To find the domain of our given function, we will find the number that will make our denominator 0 and the domain of square root function will be the values of x that will make our numerator non-negative.

Undefined points for our given function:

[tex](x+4)(x-6)=0[/tex]

[tex]x+4=0\text{ or }x-6=0[/tex]

[tex]x=-4\text{ or }x=6[/tex]  

The domain of denominator is all values of x, where x is not equal to negative 4 and positive 6.

Non negative values for radical:

[tex]x+1\geq 0[/tex]

[tex]x+1-1\geq 0-1[/tex]

[tex]x\geq -1[/tex]

The domain of numerator is all value of x greater than or equal to negative

Upon combining real regions and undefined points for our given function, the domain of our given function will be all values of x greater than or equal to negative 1, where x is not defined for 6.

Therefore, domain of our given function is [tex]x\geq -1,x\neq 6[/tex].

- x = - 14 ( multiply both sides by - 1 )

x = 14

corresponding angles

Answer: Corresponding angles.

Step-by-step explanation:

They cant be supplementary, two angles are supplementary when their addition is equal to 180°, in this case, the supplementary angles are 1 with 3, and 5 with 7, for example.

Vertical angles mean that they are in opposite quadrants, so this option can be discarded. (an example of this are angles 1 and 4)

Alternate interior angles mean that the angles are in a "touching" quadrant. so this option can be discarded (an example of this can be angles 1 and 6)

Corresponding angles mean that both angles are in the same quadrant. In this case, you can see that both angles are in the top left quadrant, so they are corresponding angles.

Determine the measure of angle AGC

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

so

[tex]m<AGC=\frac{1}{2}[81\°+59\°][/tex]

[tex]m<AGC=\frac{1}{2}[140\°][/tex]

[tex]m<AGC=70\°[/tex]

step 2

Determine the measure of angle FGC

we know that

[tex]m<AGC+m<FGC=180\°[/tex] ----> by supplementary angles

so

Step-by-step explanation:

AD is enlarged to JM

AD² = 2² + 1² = 4 + 1 =5

AD =  √5

then you plug in JM

JM² = 6² + 3² = 36 + 9 = 45

JM = √45 = 3 √5

so if

JM=3 AD

then

ML= 3 DC

then you add

5+3=8

the coordinates for point L are (8, 4)

Answer:

Option B is right.

Step-by-step explanation:

Given that an artist designed a badge for a school club.

ABCD is given in the picture.

AD = [tex]\sqrt{(-7+8)^2 +(7-5)^2} \\=\sqrt{5}[/tex]

If JKLM is enlargement of ABCD, then scale factor would b the ratio of AD to JM

JM = [tex]\sqrt{(5-2)^2+(4+2)^2} \\=\sqrt{45} \\3\sqrt{5}[/tex]

Scale factor = 3

AB = 3 hence JK = 9

DC = 1 and so ML = 3

ML is parallel to x axis with a distance of 3 units.

COordinates of L = (5+3, 4) = (8,4)

Option B is right
