You win $10 000 in a Best Math Student competition. Being a generous person, you decide to invest the money in two local busines

ses to help them get off the ground. The businesses are Paul’s Paper and Tiffany’s Tyres. They offer the following annual interest rates return to encourage your investment;
PP – 10% p.a.

TT – 5% p.a.

The investment's combined return is $620 after one year. How much was invested in each company?

The amount invested in each company is :

  • Amount invested in PP = $2400
  • Amount invested in TT = $(10000 - 2400) = $7600

Using the simple interest relation:

Simple interest = principal × rate × time

Total amount = 10000

Let :

principal invested in PP = r

HENCE, amount invested in TT = 10000 - r

Total interest earned on both investments = $620

PP investment return + TT investment return = 620

(r × 10% × 1) + (10000 - r × 5% × 1) = 620

0.1r + 500 - 0.05r = 620

0.05r = 620 - 500

0.05r = 120

r = 120 / 0.05

r = 2400

Hence,

Amount invested in PP = $2400

Amount invested in TT = $(10000 - 2400) = $7600

Which transformations could have taken place? select two options. r0, 90° r0, 180° r0, 270° r0, –90° r0, –270°
Lelechka [254]

The complete question is

"One vertex of a polygon is located at (3, –2). After a rotation, the vertex is located at (2, 3). Which transformations could have taken place? Select two options. R0, 90° R0, 180° R0, 270° R0, –90° R0, –270°"

The transformations that could have taken place are R0, 270°or R0, -90°

Let the vertex be V.

So, we have:

V = (3, –2)  before rotation

V' = (2, 3) after rotation

The possible transformations from V to V' are;

A 90 degrees counterclockwise rotation (r0, -90) is given :

(x, y) --(-y , x)

So,

(3, –2) --- (2, 3)

A 270 degrees clockwise rotation (r0, 270) is given :

(x, y) --(-y, x)

So,

(3, –2) --- (2, 3)

By comparing the endpoints of the rotations to V' = (2, 3), we can conclude that the transformations that could have taken place are: r0, 270°or r0, -90°.

The scatter plot below shows the relationship between the diameter (x), in mm, and mass f(x), in grams, of a berry: ordered pair
kkurt [141]
The function would be f (x) = 0.4x - 4.

Explanation
We can see that this is linear, since it increases at a constant rate.  We find the slope using the formula
m=(y₂-y₁)/(x₂-x₁) = (0.8-0.4)/(12-11) = 0.4/1 = 0.4

We use point-slope form to write the initial equation:

y-y₁ = m(x-x₁)
y-0.4 = 0.4(x-11)

Using the distributive property:
y-0.4 = 0.4*x - 0.4*11
y-0.4 = 0.4x-4.4

Add 0.4 to both sides:
y-0.4+0.4 = 0.4x-4.4+0.4
y=0.4x-4
