Determine the number of real solutions of -2x^2+5x-3=0

Mathematics
1 answer:
Tema [17]3 years ago
8 0

Answer:

Two distinct real solutions.

Step-by-step explanation:

Given the equation in the form ax^2+bx+c=0, you need to find the Discriminant with this formula:

D=b^2-4ac

For the equation -2x^2+5x-3=0 you can identify that:

a=-2\\b=5\\c=-3

Then, substituting these values into the formula, you get that the Discriminant is:

D=5^2-4(-2)(-3)

D=1

 Since D>0, then -2x^2+5x-3=0 has two distinct real solutions.

Select the three equations that pass through the points (-4, -16) and (5,2).
dezoksy [38]

Answer:

The equation of the line is y-2 = 2(x - 5), that passes through points (-4, -16)\ and\ (5,2)

Step-by-step explanation:

Given points are (-4, -16)\ and\ (5,2)

We need to write the equation of the line that passes through these points

First, we will find slope of this line

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-(-16)}{5-(-4)}\\\\m=\frac{2+16}{5+4}\\\\m=\frac{18}{9}=2

So, our slope is 2. Now, we will plug the point (5,2) in the equation below.

(y-y_1)=m(x-x_1)\\y-2=2(x-5)\\

So, the equation of the line is y-2 = 2(x - 5).

Someone please please help me with this !
Elanso [62]

Answer:

551.8 feet

Step-by-step explanation:

We are given

Adjacent = 1300 feet

Opposite = x

Angle = 23°

We solve using the trigonometric function Tangent

tan θ = Opposite/Adjacent

tan 23 = x/1300 feet

Cross Multiply

x = tan 23 × 1300 feet

x = 551.81726107 feet

Approximately = 551.8 feet

The Length of the building = 551.8 feet
