which function is nonlinear ?y=4x^3 , y=4x+3 , y=-4/3x

Answer:

cos(A) = 12/13

Step-by-step explanation:

There are several ways to remember trigonometric functions, but my personal favorite is:

SOH - CAH - TOA

Where Sin(angle) = Opposite/Hypotenuse

Cos(angle) = Adjacent/Hypotenuse

and Tan(angle) = Opposite/Adjacent

The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.

The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).

The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.

The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

10% raise in $20 is $2, so its only $2 more, so each hour she would earn $2 more.

Option D is the answer. $200

Answer:

Company A:

150 x 3 = $450

6/100 x 150 = $9

450 + 9 = $459

Company B:

3.10 x 150 = 465

4/100 x 150 = 6

465 + 6 = $471

Company C:

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

---------------------------

       23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

5x+2y =19

Substitute y=2

5x+2(2) =19

5x+4 = 19

Subtract 4 from each side

5x +4-4 =19-4

5x= 15

Divide by 5

5x/5 = 15/5

x=3

The solution is

Step-by-step explanation:

Considering the equation of the parabola in vertex form, it is found that a number of -100 would have to be added to complete the square.

The equation of a quadratic function, of vertex (h,k), is given by:

[tex]y = a(x - h)^2 + k[/tex]

In which a is the leading coefficient.

In this problem, the equation is:

[tex]x^2 - 20x + 24[/tex]

Placing it in vertex form, we would have:

[tex](x - 10)^2 + 24 + c[/tex]

Applying the square of the subtraction:

[tex](x - 10)^2 = x^2 - 20x + 100[/tex]

Hence, a number of -100 would have to be added to complete the square.

Answer:

A= 28.27 ft²

Step-by-step explanation:

if its trying to find area for a circle then we use the formula A=πr²

A=π(3)²

A= 28.27 ft²

Answer:

the answer is 18.85ft

Step-by-step explanation:

the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:

C = 2πr

input the values you have into the formula

C= 2 x π x 3

(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)

put that into your calculator and youll get the answer

C= 18.8495559215

(i rounded the answer to two decimal places = 18.85ft)

The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.

Answer:

The factors are 3 and -9

Step-by-step explanation:

The given trinomial is [tex]x^2-6x-27[/tex].

We need to find two factors. We know that,

3(9) = 27

So,

[tex]x^2-6x-27[/tex] can be written as :

[tex]x^2+3x-9x-27[/tex] as two factors add up to get -6 and multiply to get -27.

Hence, the factors are 3 and -9.

Answer:

x=-1, y=1

Step-by-step explanation:

Answer:

( -1, 1 )

Step-by-step explanation:

To solve, graph the equations and find the point of intersection.

when graphed these equations intersect at (-1, 1)

To double-check and make sure it's correct, plug in a solve.

x = -1

y = 1

y = 2(-1) + 3

1 = 2(-1) + 3

1 = -2 + 3

1 = 1

y = x + 2

1 = (-1) + 2

1 = 1

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work

Answer:

40 shots total.

Step-by-step explanation:

First, change the percentage to a decimal:

80% = 80/100 = 0.80

Next, divide the amount of baskets made (32) with the decimal gotten to get the  total amount of shots:

32/0.80 = 40

Brandon took a total of 40 shots.

Check. Divide 32 (shots made) with the 40 (total shots in all):

32/40 = 0.8 = 80%.

Answer:

y=2/7x+19/7

Step-by-step explanation:

Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7

Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:

y=2/7x+b

3=2/7(1)+b

3=2/7+b

21/7=2/7+b

19/7=b

Therefore, our final equation is y=2/7x+19/7
