Step-by-step explanation:

Answer: They both are located at (2,3)

Step-by-step explanation:

The sign that A and C are related is that they both have the same distance from the y axis.

a pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Given that the coordinates A and C how are related now as we can see that both A and C are the same amount of distance by the y-axis.

This also can be seen by the coordination of A and C.

Answer:

The D cells are worth $2.20, and the C cells are worth $1.90.

Step-by-step explanation:

This can be written as:

4x + 2y = 12.60

6x + 4y =20.80

Our goal is to find one variable, then use that information to find the other.

If we multiply the top function by -1.5, we get:

-6x - 3y = -18.90

We can add this to the previous equation.

  -6x - 3y = -18.90

+ 6x + 4y = 20.80

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

             y = 1.90

The C cells are worth $1.90.

Plug this value into one of the other equations and solve for x.

4x + 2y = 12.60  

4x + 2(1.90) = 12.60

4x + 3.80 = 12.60  

4x = 8.80

x = 2.20

The D cells are worth $2.20.

Check these values in the other equation.

6x + 4y = 20.80

6(2.20) + 4(1.90) = 20.80

13.20 + 7.60 = 20.80

20.80 = 20.80

Answer:

  C = $1.90 each

  D = $2.20 each

Step-by-step explanation:

Given:

  Power pack A:   4D + 2C = 12.60

  Power pack B:   6D + 4C = 20.80

Isolate any one variable:

  4D + 2C = 12.60

  4D = 12.60 - 2C

  D = 3.15 - 0.5C

Substitution to find cost of C cell battery:

  6D + 4C = 20.80

  6(3.15 - 0.5C) + 4C = 20.80

  18.9 - 3C + 4C = 20.80

  18.9 + C = 20.80

  C = 1.90

Substitution to find cost of D cell battery:

  4D + 2C = 12.60

  4D + 2(1.90) = 12.60

  4D + 3.8 = 12.60

  4D = 8.8

  D = 2.20

Answer:

49m/s

59.07 m/s

Step-by-step explanation:

Given that :

Distance (s) = 178 m

Acceleration due to gravity (a) = g(downward) = 9.8m/s²

Velocity (V) after 5 seconds ;

The initial velocity (u) = 0

Using the relation :

v = u + at

Where ; t = Time = 5 seconds ; a = 9.8m/s²

v = 0 + 9.8(5)

v = 0 + 49

V = 49 m/s

Hence, velocity after 5 seconds = 49m/s

b) How fast is the ball traveling when it hits the ground?

V² = u² + 2as

Where s = height = 178m

V² = 0 + 2(9.8)(178)

V² = 0 + 3488.8

V² = 3488.8

V = √3488.8

V = 59.07 m/s

Answer:

[tex]t=4820 y[/tex]

Step-by-step explanation:

a) The half-life equation is given by:

[tex]t_{1/2}=\frac{ln(2)}{k}[/tex]

b) Using the decay equation we have:

[tex]Q(t)=15e^{-0.0001438t}[/tex]

we need to find t when [tex]Q(t)=\frac{Q_{0}}{2}[/tex]

[tex]7.5=15e^{-0.0001438t}[/tex]

[tex]0.5=e^{-0.0001438t}[/tex]

[tex]ln(0.5)=-0.0001438t[/tex]

[tex]t=\frac{ln(0.5)}{-0.0001438}[/tex]

[tex]t=4820 y[/tex]

Therefore, it will take 4820 years to decay to half the original amount.

vertical angles theorem

Corresponding angles are two or more angles that have similar properties. Thus they have equal measures.

The required prove is given in the explanation below:

Considering the given diagram, it can be observed that:

<1 ≅ <3 and <2 ≅ <4     (vertically opposite angle theorem)

Also,

<5 ≅ < 7 and <6 ≅ <8    (vertically opposite angle theorem)

m ⊥ n and a ⊥ b             (given)

Thus,

<1 + <2 + <3 + <4 = [tex]360^{o}[/tex] (sum of angles at a point)

Also,

<5 + <6 + <7 + <8 = [tex]360^{o}[/tex]  (sum of angles at a point)

Therefore,

<1 ≅ <7                             (corresponding exterior angle property)

Therefore by corresponding exterior angle theorem, <1 ≅ <7.

Answer:

ST = 16

Step-by-step explanation:

The similar triangles are given as triangle PQR similar to triangle STU.

That makes sides PQ and ST corresponding sides. It also makes sides PR and SU corresponding sides. The ratios of the lengths of corresponding sides of similar triangles are equal.

[tex] \dfrac{ST}{PQ} = \dfrac{SU}{PR} [/tex]

[tex] \dfrac{5x + 1}{36} = \dfrac{11x - 5}{63} [/tex]

Multiply both sides by 9.

[tex] \dfrac{5x + 1}{4} = \dfrac{11x - 5}{7} [/tex]

Cross multiply.

[tex] 7(5x + 1) = 4(11x - 5) [/tex]

Distribute on both sides.

35x + 7 = 44x - 20

Subtract 44x from both sides.

-9x + 7 = -20

Subtract 7 from both sides.

-9x = -27

Divide both sides by -9.

x = 3

ST = 5x + 1 = 5(3) + 1 = 15 + 1 = 16

Answer: ST = 16

There's a way to think about it, in case you get other questions like this.

When you look at your problem, take out the 35. Out of the picture.

Look at 25%. 25% x 4 = 100% Meaning 4 is golden.

Then bring back the 35 and multiply it by 4. It gives you 140.
