Answer: 1.3%
Step-by-step explanation:
To find rate of interest (r) per annum for a fund deposit by depositor .
Initial saving payment P= $1,000
Amount after three years A =$1,040.40
we know that
r=0.013×100=1.3%
Given:
Right triangle A: Base = 2 inches and Height = 7 inches.
Right triangle B: Base = 10 inches and Height = 35 inches.
To find:
The scale factor applied to Right triangle A to produce Right triangle B.
Solution:
We have,
Base of right triangle A = 2 inches
Base of right triangle B = 10 inches
Now,
Therefore, the scale factor of 5 applied to Right triangle A to produce Right triangle B.

Answer:
<h2>
70 dollars</h2>
Step-by-step explanation:
12·3=36
2·3=6 (this is the shipping cost for Hana's)
36+6= 42
Next
12·2=24
2·2=4
24+4=28
28+42= 70
Answer:
a-bi
Step-by-step explanation:
If a quadratic equation lx^2+mx+n=0 has one imaginary root as a+bi then the other root is the conjugate of a+bi = a-bi
Because we have l, m and n are real numbers and they are the coefficients.
Sum of roots = a+bi + second root = -m/l
When -m/l is real because the ratio of two real numbers, left side also has to be real.
Since bi is one imaginary term already there other root should have -bi in it so that the sum becomes real.
i.e. other root will be of the form c-bi for some real c.
Now product of roots = (a+bi)(c-bi) = n/l
Since right side is real, left side also must be real.
i.e.imaginary part =0
bi(a-c) =0
Or a =c
i.e. other root c-bi = a-bi
Hence proved.
