Answer:

The correct option to tell whether a relationship is proportional or not is;

[tex]\dfrac{y}{x}[/tex]

Step-by-step explanation:

A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'

Therefore, y = k · x, from which we have;

[tex]\dfrac{y}{x} = k = Contant[/tex]

Therefore we can use [tex]\dfrac{y}{x}[/tex] to tell whether a relationship is proportional or not proportional.

Answer:

  x° = 29°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relevant trig relationships. Here, you have the hypotenuse and the side opposite the unknown angle. So, the appropriate relation is ...

  Sin = Opposite/Hypotenuse

  sin(x°) = 12/25

  x° = arcsin(12/25) ≈ 28.69°

The value of x is about 29.

Answer:

g has an average rate of change of zero at the intervals [-5,4] and [-2,2]

Step-by-step explanation:

When we talk of the average rate of change, we mean the change in y values divided by the change in x values

Once the change in y-values is zero, then over that interval, the average rate of change is zero

at the point t =- 5, g(t) = 6; at the point t = 4, g(t) = 6

As we can see here, within the interval [-5,4]; the average rate of change is 0

This same pattern is repetitive at points or ranges where we have same values for g(t)

such as;

[-2,2]

Answer:

90deg

Step-by-step explanation:

If the angles are supplementary, that means mA + mB = 180*

we know that

mA = (2x + 8)deg

mB = (2x + 8)deg = mA

mA + mB = 180deg

mB + mB = 2mB = 180deg

mB = 90deg

Note, that we did not need to compute x even, because the angles were the same.

Answer:

11.18

Step-by-step explanation:

Pythagorean Theorem:

a² + b² = c²

The hypotenuse is c.

10² + b² = 15²

Square 10 = 100

Square 15 = 225

100 + b² = 225

225 - 100 = 125

Find the Square Root of 125.

Answer:

$38.40

Step-by-step explanation:

20% of $48 is 9.60

48- 9.60= 38.40

Answer:

$38.40

Step-by-step explanation:

1. convert the percentage into a decimal by dividing x/100.

         20/100 =  0.2

2. multiply by the original price.

         0.2 * 48 = 9.6

3. subtract the discount.

         $48 - $9.60 = $38.40

Answer:

Step-by-step explanation:

The equation of a circle is (x-h)^2+(y-k)^2=r^2 where r is the radius of the circle and (h,k) is the coordinates of the center of the circle. We can see that the radius is 3 units and we are given the location of the center as (-3,1) so

Answer: $335,633

Step-by-step explanation:

First find the number of years difference:

= 2025 - 1985

= 40 years

Use the compound interest formula to find the answer:

= Value * ( 1 + rate) ^ no. of years

= 125,000 * ( 1 + 2.5%)⁴⁰

= $335,633

Answer:

6ft tall

Step-by-step explanation:

Given we know that the scale is 1 in 2ft.

Using this information we know we could divide 12/2=6. We also know that we could multiply 2×6=12. Therefore, we know that the model plane is 6ft tall.
