Answer:
y=-29.98
Step-by-step explanation:
y=2/3(6)^2-5(6)
y=2/108-30
y=1/54-30
54y=1-1620
y=-1619/54
y=-29.98
Answer:
c = 29.5 or
c = 59/2
Step-by-step explanation:
2 (4 + c) = 67
8 + 2c = 67
8 - 8 + 2c = 67 - 8
2c = 59
c = 29.5
Answer:
b = 11
Step-by-step explanation:
the standard form of a quadratic equation is ax² + bx + c = 0 ( a ≠ 0 )
given
x² + 28 = - 11x ( add 11x to both sides )
x² + 11x + 28 = 0 ← in standard form
with b = 11
This question is incomplete because it lacks the diagram of the right angled triangle. Find attached to this answer the diagram of the right angle triangle.
Answer:
d-50
Step-by-step explanation:
Looking at the attached diagram, the only way to solve for this is the use of the trigonometric function. The trigonometric function to be used is the cosine function.
From the diagram, we are given
Hypotenuse = AB = 14
Adjacent = AC = 9
The measure of angle A to the nearest degree is calculated as:
cos θ = Adjacent / Hypothenuse
cos θ = 9/14
θ = cos -¹ (9/14) or arccos(9/14)
θ = 49.994799115°
To the nearest degree = 50°
Therefore,the measure of angle A to the nearest degree = 50°
