a) Imagine you and your friend get a new card with an 18% APR and a $10 minimum payment and use this card to purchase the same mobile phone. If the first friend pays the minimum each month, while the second friend pays $20, what will their balances be after one month?
FYI THE PHONE COSTS 300$

Answer:

f(x) = -½x + 16

Step-by-step explanation:

Using two points in the line, (0, 16) and (4, 14), we can write an equation for the linear function in the slope-intercept form, f(x) = mx + b, by finding the slope (m) and the y-intercept (b), then substituting each of the value into f(x) = mx + b.

✔️Slope (m) = change in y/change in x

Using, (0, 16) and (4, 14),

Slope (m) = (14 - 16)/(4 - 0) = -2/4

m = -½

✔️y-intercept (b) would be the value of y when x = 0, or the point at which the y-axis is intercepted by the line.

Thus,

When x = 0, y = 16

Therefore,

b = 16

✅Write the equation of the function by substituting m = -½ and b = 16 into f(x) = mx + b

Thus:

f(x) = -½x + 16

Step-by-step explanation:

2x=10

divide through by 2

2X/2=10/2

X=5.

prove: 2x is simply 2 multiplied by the value of X.

when X is 5, it means 2 X 5= 10

The value of x makes the equation 2x = 10 true is x=5.

The given equation is

2x=10

We have to determine the value of x

We have to apply the opposite operation of multiplication.

The division is the opposite operation of multiplication.

divide through by 2

2X/2=10/2

X=5.

2x is simply 2 multiplied by the value of X.

when X is 5, it means 2 X 5= 10.

The exponential equation 3⁴ = 81 can be written as a logarithmic equation in the form will be 4 = ㏒₃ 81. Then the correct option is D.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The exponential equation is given below.

3⁴ = 81

Take log on both sides with base 3, then we have

Answer:

Its 67.9 but technically its 67.912 *hope this helps

Step-by-step explanation:

Right scalene triangle.

Sides: a = 66   b = 16   c = 67.912

Area: T = 528

Perimeter: p = 149.912

Semiperimeter: s = 74.956

Angle ∠ A = α = 76.373° = 76°22'23″ = 1.333 rad

Angle ∠ B = β = 13.627° = 13°37'37″ = 0.238 rad

Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 16

Height: hb = 66

Height: hc = 15.55

Median: ma = 36.674

Median: mb = 66.483

Median: mc = 33.956

Inradius: r = 7.044

Circumradius: R = 33.956

Vertex coordinates: A[67.912; 0] B[0; 0] C[64.142; 15.55]

Centroid: CG[44.018; 5.183]

Coordinates of the circumscribed circle: U[33.956; 0]

Coordinates of the inscribed circle: I[58.956; 7.044]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 103.627° = 103°37'37″ = 1.333 rad

∠ B' = β' = 166.373° = 166°22'23″ = 0.238 rad

Answer:

Point E

Step-by-step explanation:

Notice that point E is the only point where you can draw a straight line from E to A' to A, E to B' to B, etc. That is, the line doesn't have to turn or bend to reach these three points. This doesn't work with any other point, so you know E is the point of dilation.

You can more firmly determine this by looking at the ratios of the distances. Notice how E is the only point where the ratio from of E to A and E to A' is equal to the ratio from of E to B and E to B', and so on for each vertex of the quadrilateral.

Answer:

n = 2

Step-by-step explanation:

The intersecting chord theorem describes the relation between line segments in a circle formed by intersecting chords.

The product of line segments in a chord is equal to the product of line segments in the other chord if intersecting in a circle.

This means that:

(n + 16)(4) = (n + 6)(9)

4n + 64 = 9n + 54

–4n –4n

64 = 5n + 54

–54 –54

10 = 5n

5n = 10

÷5 ÷5

n = 2

________________

4n + 64 = 9n + 54

4(2) + 64 = 9(2) + 54

8 + 64 = 18 + 54
