Alexander is a stockbroker. He earns 11​% commission each week. Last​ week, he sold ​$5,400 worth of stocks. How much did he make last week in​ commission? If he averages that same amount each​ week, how much did he make in commission in​ 2011?

Answer:

f( x) = x ^2 + 1

The equation  f( x) = x² + 1 makes the table true.

Two or more expressions with an equal sign is called as equation.

The given  table is

x     y

0     1

2     5

5     26

7      50

The table value satisfy with the function f( x) = x² + 1=y

if x=0, then y=f(0)=0² + 1=1

if x=2, then y=f(2)=2² + 1=4+1=5

if x=5, then y=f(5)=5² + 1=25+1=26

if x=7, then y=f(7)=7² + 1=49+1=50

Therefore f(x)=x² + 1 is the equation of table.

Step-by-step explanation:

350x.04= 14 for 1st year

350+14= 364 for 1st year

364×.04= 14.56 for 2nd year

364+14.56= 368.56 for 2nd year

368.56+15.14= 393.70 yr 3 yrs

Answer:

The answer is 42.

Step-by-step explanation:

We start by using the Simple Interest Formula.

I=P x R x T

Key

P: Principal, R: Rate and T: Time

>P=$350

>R=4% or .04

>T= 3 (for 3 years)

Answer:

∠ BAF = 140°

Step-by-step explanation:

Since BD is a tangent to the circle at point B , then

∠ ABD = 90°

The exterior angle of a circle is equal to the sum of the 2 opposite interior angles.

∠ BAF is an exterior angle, thus

∠ BAF = ∠ ABD + ∠ BDA = 90° + 50° = 140°

[tex]f(x) = {x}^{2} + 7 [/tex]

[tex]y = {x}^{2} + 7 [/tex]

Subtract the sides of the equation minus 7

[tex]y - 7 = {x}^{2} [/tex]

Take the square root of both sides of the equation

[tex]x = \sqrt{y - 7} [/tex]

So ;

[tex] {f}^{ - 1}(x) = \sqrt{x - 7} [/tex]

Yes; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

The side lengths  8, 15, and 20 form the sides of a .triangle

In order to determine whether the length of the sides forms a triangle, we will use the theorem that states that:

Given the side lengths 8, 15 and 20

Taking the sum of any two sides;

8 + 15 = 23

Since 23 > 20 (third side), this shows that the theorem is true

Similarly;

Also;

Since all the conditions are met, hence the side lengths form a triangle.

Answer:

B multiply -6 and 3

Answer:

Step-by-step explanation:

The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as;

M(X,Y) = {(x1+x2)/2, (y1+y2)/2}

Given the points A(h, k) and B(h,j)

x1 = h, y1 = k, x2 = h, y2 = j

Substitute into the formula;

M(X,Y) = {(x1+x2)/2, (y1+y2)/2}

M(X,Y) = {(h+h/2, (k+j)/2}

M(X,Y) = {(2h)/2, (k+j)/2}

M(X,Y) = {h, k+j/2}

hence the coordinates of point M is {h, k+j/2}

Answer:

[tex]\angle 1=39\textdegree[/tex]

Step-by-step explanation:

Remember that the sum of the interior angles of a triangle always equal 180. Therefore:

[tex]\angle 1+\angle Y+102=180[/tex]

Let's subtract 102 from both sides. This yields:

[tex]\angle 1+\angle Y=78[/tex]

Now, notice the that both ∠1 and ∠Y have exactly one arc mark.

Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:

[tex]\angle 1=\angle Y[/tex]

So, we can substitute ∠Y for ∠1 for our equation. This yields:

[tex]\angle 1+\angle 1=78[/tex]

Combine like terms:

[tex]2\angle 1=78[/tex]

Divide both sides by 2. So, the measure of our angle is:

[tex]\angle 1=39\textdegree[/tex]

Answer:

y=1.5x+1; x= -0.6

y= -0.25x-6; x= -24

Step-by-step explanation:

y=1.5x+1

0=1.5x+1 (To find x-intercept/xero, substitute y=0)

-1.5x=1

x= -2/3 or x= -0.6

y= -0.25x-6

0= -0.25x-6

0.25x= -6 (Move variables to the left-hand side and change its sign)

x= -24

Answer:

k = -3x

Step-by-step explanation:

To find the slope, use rise over run

I started from (0, 0)

To get to the next whole number point, you must go up (rise) 3 and go back (run) 1

Since we are going back, the slope is negative.

The rise over run is -3/1 which simplifies to -3

To find y-intercept, we look at the point when x = 0. When x = 0, y = 0 so the y-intercept is 0 (which means you don't have to include it into the equation

y = -3x or k if that's what you use

Answer:

y= 1/3x - 3

Step-by-step explanation:

The y-axis is -3

In order to find slope you do rise/run
