Answer:
C. The discriminant is negative, so there are no solutions.
Step-by-step explanation:
We see that the given figure is a graph of a parabola.
The equation of the given parabola is
.
Simplifying the equation in quadratic form, we get,
The equation is
i.e.
i.e.
.
We know that the discriminant of a quadratic equation
is given by ![D=b^{2}-4ac](https://tex.z-dn.net/?f=D%3Db%5E%7B2%7D-4ac)
So, from the equation
, we have,
a = 1, b = -6 and c = 10
Thus, the discriminant is ![D=(-6)^{2}-4\times 1\times 10](https://tex.z-dn.net/?f=D%3D%28-6%29%5E%7B2%7D-4%5Ctimes%201%5Ctimes%2010)
i.e. ![D=36-40](https://tex.z-dn.net/?f=D%3D36-40)
i.e. ![D=-4](https://tex.z-dn.net/?f=D%3D-4)
So, the discriminant is -4 i.e. negative.
Hence, as the discriminant is negative, there are no solutions.
A. The graph is decreasing. For every time the x gets bigger the y value decreases.
Answer:
62.5 feet
Step-by-step explanation:
The perimeter of the composite figure is the distance around the figure. It is found by adding each of the side lengths around the figure.
Here P = 4 + 5.5 + 14 + 12.5 + 18 + 8.5 = 62.5
Answer:
2520
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference.
To find the number of terms given
= - 10 , d = - 2 and a₁ = 100, then
100 - 2(n - 1) = - 10 ( subtract 100 from both sides )
- 2(n - 1) = - 110 ( divide both sides by - 2 )
n - 1 = 55 ( add 1 to both sides )
n = 56 ← number of terms
Given n, a₁ and a₅₆ , then the sun of the terms is
=
(a₁ + a₅₆ )
=
(100 - 10) = 28 × 90 = 2520
