Your answer for this is C
Answer:
Step-by-step explanation:
Here, we want to solve the given quadratic equation using the quadratic formula
We need to rewrite the equation in the standard form;
-4x^2 + 3x + 5 = 0
we have the value a as -4
value b as 3
C = 5
we then substitute these values into the quadratic formula as seen in the attachment
The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of cos(28°) is -0.9626.
<h3>What are Trigonometric functions?</h3>
The trigonometric function gives the ratio of different sides of a right-angle triangle.

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
The cosine is the ratio of the base of the triangle and the hypotenuse of the triangle. Therefore, The value of cos(28°) is -0.9626.

Answer:
Step-by-step explanation:
So we have : c + 2.5 < 4.3
And it's asking whether c = 1.8 is a solution.
Substitue c = 1.8 in, we get :
1.8 + 2.5 < 4.3
4.3 < 4.3 (not true)
So, c = 1.8 is NOT a solution.
