Answer:
So the portion of the loan lent at 4% is 21000(0.5955) = $12,505.5
And the portion of the loan lent at 15% is 21000(0.4045) = $8494.5
Step-by-step explanation:
This problem can be solved in several ways. The way I like is as follows.
Ask yourself at what interest would $ 21,000 yield and interest of $ 2,215 in one year ? The equation to solve is:
21000(P) = 2215
P = 0.1055 or 10.55 %
This number is a weighed average of the 4% yield and the 15% yield so the next equation to solve is
10.55 = 4(1 – X) + 15X
Where X is the proportion of the loan given at the indicated interest. So
10.55 = 4 – 4X + 15X
6.55 = 11X
X = 0.5955
1-X = 0.4045
So the portion of the loan lent at 4% is 21000(0.5955) = $12,505.5
And the portion of the loan lent at 15% is 21000(0.4045) = $8494.5
I think its 2/5 = .4 <span>because of the negative in the exponent, it is 0.4</span> Hope I helped :)

1st Question:
(2,-3)
(3,-1)
(3,1)
(4,1)
(5,3)
2nd Question
y=-2+10x (graph in desmos to be sure)
Step-by-step explanation:
1st Question: just write the x and the y that the x is pointing to
2nd Question: type the points on a table in desmos and find a equation that goes through the same line
Answer:
(3,4) because only the y would change when it is being reflected over the x axis :)

Answer:
12,000 m³
Step-by-step explanation:
- Area of it's base = 900 m²
- Height of the pyramid = 40 m
The volume of a pyramid = 1/3 × area of base × height
= 1/3 × 900 × 40
= 300 × 40
= 12,000 m³
