Answer:
B
Step-by-step explanation:
I think its B dont quote me
Answer:
x =19.2
y=29.8
Step-by-step explanation:
We will use the law of sines to solve this problem
sinA sin B
----------- = -------------
a b
sin 55 sin 40
--------- = ---------------
24.5 x
Using cross products
x sin 55 = 24.5 sin 40
Divide by sin 55
x = 24.5 sin 40 / sin 55
x =19.22512011
To one decimal place
x =19.2
To find the angle opposite y, we know the three angles of a triangle add to 180
y = (180-40-55) = 85
sin 55 sin 85
--------- = ---------------
24.5 y
Using cross products
y sin 55 = 24.5 sin 85
Divide by sin 55
y = 24.5 sin 85 / sin 55
y =29.79516474
To one decimal place
y=29.8
Answer:
I think C i could be wrong tho
Step-by-step explanation:
Answer:
Complementary angles are 90 degrees
Step-by-step explanation:
Supplementary angles are 180
Hope this helps:))))
Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.
<h3>
What can we say about the discriminant?</h3>
For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ac
- If D = 0, there is only one real zero.
- If D > 0, there are two real zeros.
- If D < 0, there are two complex zeros.
In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.
