Answer:
1 solution. y= 5/4x - 1/2
a ≈ 5.2, B ≈ 50°, C ≈ 95°
Solution:
Given data:
A = 35°, b = 7, c = 9
Using cosine law,
Taking square root on both sides.
a ≈ 5.2
Using sine law,
Multiply by 7 on both sides.
Switch the sides.
Sin B = 0.772
B ≈ 50°
Sum of all the angles of a triangle = 180°
A + B + C = 180°
35° + 50° + C = 180°
85° + C = 180°
C = 180° - 85°
C = 95°
Hence a ≈ 5.2, B ≈ 50°, C ≈ 95°.

A future value ?
P principle 3700
i interest rate 0.0184
K compounded quarterly 4
N time 6 years
A=3,700×(1+0.0184÷4)^(4×6)
A=4,130.84
Interest earned=A-p
4,130.84−3,700=430.84
Hope it helps:-)
The given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0
<h3>Simplified Polynomials</h3>
From the question, we are to determine f(x) = -3 as a simplified polynomial
From the given information, we have that
f(x) = -2x^2 + 6x
Rewrite the the given equation properly.
Rewriting, we get
f(x) = -2x² + 6x
Also, from the given information
We have that
f(x) = -3
Thus, we can write that
- 3 = -2x² + 6x
Writing the above equation as a simplified polynomial, we get
- 3 = -2x² + 6x
2x² - 6x- 3 = 0
Hence, the given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0
