Step-by-step explanation:
TRIANGLE 1
c = 2√5
= 2 × √5
= √4 × √5
= √20
a = 2
b = ?
b² = c² - a²
= √20² - 2²
= 20² - 4
= 400 - 4
= 396
b = √396
= √36 × √11
= 6 × √11
= 6 √11
TRIAGLE 2
a = 12
b = 6√11
= √396
c = ?
c² = a² + b²
= 12² + √396
= 144 + √396²
= 144 + 396
c = √540
= √36 × √15
= 6 × √15
= 6 √15

Answer: There will be $ 1687.02 in the account after 7 years.
Step-by-step explanation:
Formula to find the accumulated amount (A) in account on principal amount (P) with rate of interest (r) in 't' years is given by :-

As per given, P = $1400
r= 2.7% = 0.027
t= 7 years
Then,

Hence, there will be $ 1687.02 in the account after 7 years.
Suppose x is sold, $280 each , and y is the total financial cost. The first equation in the system is then certainly y = 280x.
The vertex form <span>y-k = a(x-h)^2 where (h,k) is the vertex, and y is the y-intercept.
So, plug the values in.
</span><span>11,000-24,000 = a(0-500)^2
-13,000=250,000a
a=-0.052
y-</span><span>24,000 = -0.052(x-500)^2
y= </span><span>-0.052(x-500)^2 + 24,000
This is the second equation in the system.
The answer is then A, which contain the system </span><span>of equations which can be used to determine must be sold for the company to make a profit.</span>
I think it's D. 58 because The triangle has a right angle (90 degrees), so all you have to do is subtract 32 from 90.
Answer: D. 58 degrees
