Hunter invested $750 in an account paying an interest rate of 6\tfrac{5}{8}6 8 5 ​ % compounded continuously. London invested $750 in an account paying an interest rate of 6\tfrac{1}{2}6 2 1 ​ % compounded daily. After 18 years, how much more money would Hunter have in his account than London, to the nearest dollar?

Answer:

x = 12

Step-by-step explanation:

To get the value of x, we use the mid-segment theorem of trapezoid

The theorem is that the mid-segment is half the sum of the other two segments

We have this as

;

5x - 20 = 1/2(2x + 6 + 4x + 2)

2(5x-20) = 6x + 8

5x -20 = 3x + 4

5x -3x = 4 + 20

2x = 24

x = 24/2

x = 12

Answer:

245/999

Step-by-step explanation:

Step-by-step explanation:

given

as it is right angled triangle so

Let the unknown angle be x Then

90° + 40° + x = 180° ( being sum of angles of triangle)

130° + x = 180°

x = 180° - 130°

Therefore x = 50°

Hope it will help you :)❤

Answer:

The other angle will be 50°.

Step-by-step explanation:

Given that the diagram shows a right angle triangle (90°) and the total sum of angles of a triangle is 180°. In order to find the other angle, you have to subtract :

x + 40° + 90° = 180°

x + 130° = 180°

x = 180° - 130°

x = 50°

Answer:

Y=-3x+0 or Y=-3x

Step-by-step explanation:

Y=mx+b

m=slope

b=y-intercept (where the line crosses the y axis)

The line crosses the Y axis at (0,0), so:

Y=mx+0 or

Y=mx

Slope:

Rise/run= Change in y/Change is x= 9/-3=-3

So:

Y=-3x+0 or

Y=-3x

Answer: 3x + y = 0

Step-by-step explanation: Remember that slope is represented by

rise over run from one point to the next on our graph.

To get from the point (0, 0) to (3, -9), we go down -9 units

so our rise is -9 and we run 3 units so our run is 3.

Our slope therefore or m = -9/3 or -3.

Our y-intercept is represented by the point where this line

crosses the y-axis which in this case is up 0 units.

So our y-intercept or b = 0.

Since we have the slope and y-intercept of our line,

we can now write its equation in y = mx + b form.

Since m = -3 and b = 0, that gives us y =-3x + 0.

Now we convert this equation to standard form.

Just add 3x to both sides to get 3x + y = 0.

So the equation of this lie is 3x + y = 0.

Answer:

the walking rate miles per hour is 2 miles per hour

Step-by-step explanation:

The computation of the walking rate miles per hour is shown below;

Given that

She can walk half mile in one-fourth of an hour

= Miles ÷ hours

= (1÷ 2) ÷ (1 ÷4)

= 0.50 ÷ 0.25

= 2 miles per hour

Hence, the walking rate miles per hour is 2 miles per hour

Answer:

The point representing the y-intercept is: (0, -3)

The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.

The point representing the x-intercept is: (10.5, 0)

The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5

Step-by-step explanation:

Given the linear equation

-2x+7y=-21

Determining the y-intercept

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

substituting x = 0 in the equation

-2x+7y=-21

-2(0) + 7y = -21

0+7y = -21

7y = -21

divide both sides by 7

7y/7 = -21/7

y = -3

Therefore, the point representing the y-intercept is: (0, -3)

The black dot represents the y-intercept on the attached graph. It is very clear at y = 0, x = -3.

Determining the x-intercept

We know that the value of x-intercept can be determined by setting y = 0, and determining the corresponding value of x.

substituting y = 0 in the equation

-2x+7y=-21

-2x+7(0) = -21

-2x + 0 = -21

-2x = -21

divide both sides by -2

-2x / -2 = -21 / -2

x = 21/2

x = 10.5

Therefore, the point representing the x-intercept is: (10.5, 0)

The graph of the linear equation containing the y-intercept (0, -3) and x-intercept (10.5, 0) is shown and attached below.

The red dot represents the x-intercept on the attached graph. It is very clear at x = 0, y = 10.5

Please check the attached graph.

Answer:

  16. a: (-90°, (4, 3)); b: (90°, (0, 3)); c: (-90°, (0, 0))

  17. a: (down, (4, -1)); b: (right, (4, 3)); c: (up, (5, 2))

Step-by-step explanation:

We don't know what notation you're used to seeing for rotations. Here. we'll use the form [degrees CCW, (center)]. (CW angles are negative.) In any rotation, the center is the point that is invariant (remains in the same place)

16.

a) The tail is invariant, so the rotation is (-90°, (4, 3)).

b) The tip is invariant, so the rotation is (90°, (0, 3)).

c) The origin is invariant, so the rotation is (-90°, (0, 0))

__

17.

a) The tail is invariant, so the arrow is pointing down with the tip at (4, -1).

b) The center is invariant, so the arrow is reversed. It is pointing right with the tip at (4, 3).

c) Point (2, 3) is invariant, so the arrow is pointing up with the center at (5, 0). The tip is at (5, 2).

_____

Additional comment

If you have trouble visualizing these rotations, you might find it useful to trace the arrow on a piece of (semi-)transparent medium (plastic or tracing paper) so that you can move it as required to match the descriptions in the problem statement. A pin, or a dot on your tracing, can serve to fix the center of rotation. A little hands-on never hurts in math and geometry.

Answer:

neither

Step-by-step explanation:

Parallel lines need to have the same slope.

Perpendicular lines have opposite reciprocal slopes.

-5/2 and -2/5 are opposite reciprocals nor are they equal.

Given

1/2 ( 6a + 8)

Taking common

= 1/2 * 2( 3a + 4)

= 3a + 4

Hope it will help you :)❤

Answer:

3a+4

Step-by-step explanation:

Simplify  1/2

Then you should do 1/2*(6a+8)

Then you pull out the like terms

  6a + 8  =   2* (3a + 4)

Answer:

 3a + 4

Answer:

a) x = -2+√3 and -2-√3

b) x = -1 + 2√3/3 and -1 - 2√3/3

c) x = 3.185 and 0.315

Step-by-step explanation:

To solve the following quadratic equation, we will use the general formula

x = -b±√b²-4ac/2a

a) x²+4x+1 = 0

a = 1, b = 4 and c = 1

Substitute into the formula

x = -4±√4²-4(1)(1)/2(1)

x = -4±√16-4/2

x = -4±√12/2

x = -4±2√3/2

x  = (-4+2√3)/2 and  (-4-2√3)/2

x = -2+√3 and -2-√3

b) 3x²+6x-1 = 0

a = 3, b = 6 and c = -1

Substitute into the formula

x = -6±√6²-4(3)(-1)/2(3)

x = -6±√36+12/6

x = -6±√48/6

x = -6±4√3/6

x  = (-6+4√3)/6 and  (-6-4√3)/6

x = -1 + 2√3/3 and -1 - 2√3/3

c) 2x² - 7x + 2 = 0

a = 2, b = -7 and c = 2

x = -(-7)±√(-7)²-4(2)(2)/2(2)

x = 7±√49-16/4

x =7±√33/4

x = 7±5.74/4

x = 7+5.74/4 and 7-5.74/4

x = 12.74/4 and 1.26/4

x = 3.185 and 0.315

Answer:

A 2:3

Step-by-step explanation:

625-250= 375 which is the number of boys in the school now it's 375 and 250

250:375

= 250/375

Dividing by 5/5, we have,

50/75

Again, Dividing by 5/5, we have,

10/15

Again, Dividing by 5, we have,

2/3

Hence, the ratio 250:375 in the simplest form will be 2:3
