Identify the name of the picture

Answer:

(3) 36

Step-by-step explanation:

3x + 1 = 9

Minus 1 from both sides.

3x = 8

Divide both sides by 3.

x = 2 2/3

Plug it in.

12 (2 2/3) + 4

32 + 4

The probability of choosing a red marble is 1/6.

Probability is the chance of occurring a certain event out of total possible events that can order in a given situation.

According to the given question an urn contains 19 red marbles, 29 blue marbles, and 43 yellow marbles.

So there are total of ( 19 + 29 + 43 ) = 85 marbles.

∴ No. of sample space N(s) = 85.

No. of red marble N(red) = 19.

One marble is to be chosen from the urn without looking the probability of choosing a red marble P(red) is N(red)/N(s) which is

P(red) = 19/85

P(red) = 1/5.

[1/2, sqrt(3)/2] and [-1/2, -sqrt(3)/2] are  the unit vectors that are parallel to the tangent line to the curve.

Explain what a unit vector is?

y=2sin(x)

dy/dx equals 2 cos x at pi/6 for x.

pi/6 = 2 cos pi/6 = 2 sqrt(3)/2 = sqrt = dy/dx(pi/6) (3)

the line sqrt(3) (x-pi/6) is the tangent to y at pi/6.

Atan Theta = sqrt is the angle with the x axis (3)

θ = pi/3 radians at 60 degrees

Step-by-step explanation:

Answer:

Step-by-step explanation:

x = -3 to 3

means that they are asking for the graph from -3 to 3 on the x-axis

gradient is (-1/2) which means rise is -1 when run is 2

y-intercept is 3.

go to 3 on the y axis which means the coordinate (0,3) go downwards by 1 and to the right by 2. This will lead you to coordinate (2,-1). Now connect both points by a straight line.

∠AOM ≅ ∠BOM  because they are both congruent to the same angle, not because they are vertical angles.

From the image of the angles attached, we are given that;

∠AOM ≅ ∠DON

Now, from the vertical angle theorem, we can say that;

∠AOM ≅ ∠CON

Similarly, by vertical angles theorem, we can also say that;

∠BOM ≅ ∠DON

From transitive property of congruence, we can equally say that since ∠AOM and ∠BOM are equal to the same angle, then;

If you are using the same function equation, than you should not get the same output if you use two different inputs.

The linear combination of u and v = <3,-27>=5U+4V.

A linear combination of two or more vectors is the vector formed by multiplying two or more vectors (with distinct directions) by scalar values. The above equation demonstrates that the vector is produced by adding two vectors to three vectors.

The term "linear" has two independent meanings: geometric and algebraic. Because linear combinations essentially linear in the both senses, the expression is accurate.

Let u= <3,3> and v= <-3,3>

<3,-27> = x< 3,3> + y<-3,3> = <3x - 3y, 3x + 3y>

3x - 3y = 3 => x - y = 1

3x + 3y = -27 => x + y = -9

Adding both, we get

2x = -8 => x = -4

y = -5

So <3,-27> = -4< 3, 3 > + (-5) < -3 , 3 >

The linear combination of u and v = <3,-27>=5U+4V.

Answer:

y=1/4 -2

Step-by-step explanation:

y =mx + c

m= slope

c= y-intercept

putting the valves of x and y ( 0,-2)

-2 = 1/4(0) + c

solve for C

C = -2

substituting back to the general equation of

y= 1/4x + C

y = 1/4x - 2( ans).

Given:

[tex]\begin{aligned}&x^2+y^2=16 \\&z=x y\end{aligned}[/tex]

Express 16 as [tex]4^{2}[/tex]: [tex]x^2+y^2=16[/tex]

[tex]x^2+y^2=4^2\\x^2+y^2=4^2 \times 1[/tex]

Trignometry,

[tex]\cos ^2(t)+\sin ^2(t)=1[/tex]

Now, substitute [tex]\cos ^2(t)+\sin ^2(t)[/tex] for 1:

[tex]\begin{aligned}&x^2+y^2=4^2 \times 1 \\&x^2+y^2=4^2 \times\left[\cos ^2(t)+\sin ^2(t)\right]\end{aligned}\\x^2+y^2=4^2 \times \cos ^2(t)+4^2 \times \sin ^2(t)[/tex]

Law of indicates:
[tex]\begin{aligned}&x^2+y^2=[4 \times \cos (t)]^2+[4 \times \sin (t)]^2 \\&x^2+y^2=[4 \cos (t)]^2+[4 \sin (t)]^2\end{aligned}\\x^2=[4 \cos (t)]^2 \text { and } y^2=[4 \sin (t)]^2[/tex]

Taking positive square roots as follows:

[tex]x=4 \cos (t), y=4 \sin (t)[/tex]

Recall that, z = xy.

Now, we have:

[tex]\begin{aligned}&z=4 \cos (t) \times 4 \sin (t) \\&z=16 \cos (t) \cdot \sin (t)\end{aligned}[/tex]

Now, substitute the values:
[tex]r(t)=x_t i+y_t j+z_t k[/tex]

So, the vector r(t) is: [tex]r(t)=(4 \cos (t)) i+(4 \sin (t)) i+(16 \cos (t) \cdot \sin (t)) i[/tex]

Therefore, the vector function r(t) is written as: [tex]r(t)=x_t i+y_t j+z_t k[/tex]

A function assigns the values. The output(y) of the function y=20x + 38 if the input is -9 is -142.

A function assigns the value of each element of one set to the other specific element of another set.

Given the function y=20x+38, therefore, if the input of the function is -9, then the output can be calculated by substituting the value of x as -9. Therefore, we can write the function as,

y = 20x + 38

y = 20(-9) + 38

y = -180 + 38

y = -142

Hence, the output(y) of the function y=20x + 38 if the input is -9 is -142.

Sal sold 7 pairs of type a socks and 9 pairs of type b socks

Let the number of type a socks sold by Sal be x

Let the number of type b socks sold by Sal be y

The selling price of type a socks = 45

The selling price of type b socks = 30

Total pairs sold = 16

Total income = 585

Therefore, the equations will be

x + y = 16-------(1)

45x + 30y = 585--------(2)

Multiplying equation (1) by 30 we get

30x + 30y = 480 ------(3)
