Answer: ( -3 1/2, -1 1/4 ) that's where it is on the coordinate plane...

Step-by-step explanation:

The point  ( -3 1/2, -1 1/4 ) on the coordinate plane is shown in the figure

The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.

It is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

Given;

( -3 1/2, -1 1/4 )

The given points are marked on the coordinate plane below;

Answer:

28%

Step-by-step explanation:

92-64=28

The percentage change in Alexandria's marks would be; 44%

A percentage is a minimum number or ratio that is measured by a fraction of 100. Percentage is the ratio of  the number for which you want to find  percentage to the total number with which you want to compare or out of and multiply this ratio with 100.

The percentage of change = (change in amount / original amount ) x 100

Alexandria's  marks in first attempt = 64

Alexandria's  marks in retake = 92

Then the Change in marks = 92-64 = 28

Thus Percentage of change on her tests

= ( change in marks / initial marks) ×100

=( 28/64)×100

= 43.75 %

≈ 44 %

Therefore, the percentage change in Alexandria's marks would be; 44%

Mi papa paga $ 4275 por la renta de la casa y le queda $ 8550 para el ahorro y los demás gastos.

Step-by-step explanation:

Mi padre recibe su paga, dedica una tercera parte para pagar la renta de la casa y dispone del resto, es decir, las dos terceras partes, para ahorro y demás gastos. Entonces, calculo los rubros correspondientes:

Rubro dedicado al pago de la renta de la casa

[tex]x = \$\,12825\times\frac{1}{3}[/tex]

[tex]x = \$\,4275[/tex]

Rubro dedicado al ahorro y los demás gastos

[tex]y = \$\,12825-x[/tex]

[tex]y =\$\,12825-\$\,4275[/tex]

[tex]y = \$\,8550[/tex]

Answer:

y = 2/5

Step-by-step explanation:

Here, we want to express the equation 5y = 2 in the form of a linear equation.

A linear equation is in the form y = mx + c

What this means is that we have to isolate y

Thus, we can isolate y by dividing both sides by 5

5y/5= 2/5

y = 2/5

Answer:

Never rational, always irrational.

Step-by-step explanation:

If 1 lunch =$2.50

2 lunches = $5.00 (2.50x2)

3 lunches =$7.50

4 lunches =$10.00

5 lunches= $12.50

basically just add $2.50

Using the multiplication principle, the completed table is shown below :

The total cost for any quantity given can be obtained by taking the product of the quantity and the cost per lunch ;

Hence, the cost of quantities 1, 2, 3, and 4 are $2.50, $5.00, $7.50 and $10.00 respectively.

Answer:

Step-by-step explanation:

Given the line 2x-7y = -25

First let us get the slope of the line:

Rewrite the equation in the form y = mx+c

2x-7y = -25

-7y = -2x-25

y = -2x/-7-25/-7

y = 2/7 x +25/7

The slope of the line is 2/7

Ffor two lines to be perpendicular, the product of their slope must be -1

mM = -1

m(2/7)= -1

2m = -7

m = -7/2

Hence the lines perpendicular to the given line must be a line that has a slope of -7/2. Since we are not given option, we can say example of such line is y = -7/2 x + 15

Answer:

For the particle to move to the right, 0 ≤ t ≤ a

Step-by-step explanation:

The particle under motion on the x-axis given by the equation x(t) = 12(a−t)² for t ≥ 0, where a is a positive constant.

To find the values of t for which the particle is moving to the right, this implies that the particle must move along the positive x-axis. This implies that x(t) ≥ 0.

So, to find the value of t for which the particle moves to the right, we solve the inequality x(t) ≥ 0 ⇒ 12(a−t)² ≥ 0

12(a−t)² ≥ 0

(a−t)² ≥ 0

taking square root of both sides, we have

√(a−t)² ≥ √0

(a−t) ≥ 0

a ≥ t ⇒ t ≤ a

So, for the particle to move to the right, 0 ≤ t ≤ a.

Using derivatives, it is found that the particle is moving to the right for [tex]t > a[/tex], that is, values of t in the interval [tex](a, \infty)[/tex].

A particle is moving to the right if it's velocity is positive.

The position of the particle is given by:

[tex]x(t) = 12(a - t)^2[/tex]

The velocity is the derivative of the position, hence:

[tex]v(t) = -24(a - t)[/tex]

If will be positive if:

[tex]-24(a - t) > 0[/tex]

[tex]-(a - t) > 0[/tex]

[tex]-a + t > 0[/tex]

[tex]t > a[/tex]

Answer:

The expectation is reasonable

Step-by-step explanation:

Since Jamal runs 1 mile in 5.05 minutes, and expected to run 5 km in 15.25 minutes, we need to find if this is true. So, we need to find if he can actually run 5 km in 15.25 minutes.

Now 1 mile = 1609 m and  5 km = 5000 m. So, 5 km = 5000 m × 1mile/1609 m

5 km = 5000/1609 mile

Also since Jamal runs 1 mile in 5.05 minutes, the time it takes to run 5 km = 5000/1609 mile is 5000/1609 mile × 5.05 minutes/1 mile = 25,250/1609 minutes = 15.69 minutes.

Since our calculation shows that Jamal runs a 5 kilometer race in 15.69 minutes, the expectation that he will break the record in 15.25 minutes is reasonable. He can only break the record if he runs faster since there is a difference of 15.69 - 15.25 minutes = 0.44 minutes = 0.44 × 60 = 26.4 seconds which is quite a short time. So the expectation is reasonable.
