What is the discriminant of the quadratic equation, 4x^2-8x-5=0
Answers
Answer:
Step-by-step explanation:
4x^2-8x-5=0
The discriminant is the number under the √. In this case it's 144
Answer:
[tex]\Delta=144[/tex]
Step-by-step explanation:
For a quadratic in standard form, the discriminant is given by:
[tex]\Delta=b^2-4ac[/tex]
We have the equation:
[tex]4x^2-8x-5=0[/tex]
Hence, our a=4; b=-8; and c=-5.
Substituting into our formula, we acquire:
[tex]\Delta=(-8)^2-4(4)(-5)[/tex]
Evaluate:
[tex]\Delta=64+80[/tex]
Add:
[tex]\Delta=144[/tex]
Therefore, our discriminant is 144.
Notes:
Since our discriminant is a positive value, this tells us that our quadratic has two real roots.

340.1 ÷ 9.5 = 358
Answers
Answer:
35.8
Step-by-step explanation:
[tex]\frac{340.1}{9.5}[/tex] = 358
We know that our answer can never be greater than 358 since the dividend
is 340.1 and the divisor is 9.5;
Also,
Both values are to one decimal places and we can use this to solve the problem;
9 can divide 340 in about 37 place with a remainder of 7,
So, it is appropriate to make the solution 35.8
A rocket is 1.5miles above the earth in 20 seconds and is 8 miles above the earth in 2 minutes. What is the rockets rate of change in miles per seconds
Answers
Given:
A rocket is 1.5 miles above the earth in 20 seconds.
It is 8 miles above the earth in 2 minutes.
To find:
The rockets rate of change in miles per seconds.
Solution:
Let y be the height above the earth after x seconds.
A rocket is 1.5 miles above the earth in 20 seconds. So, the point is (20,1.5).
It is 8 miles above the earth in 2 minutes.
1 minute = 60 seconds
2 minutes = 120 seconds
So, the point is (120,8).
The rockets rate of change in miles per seconds is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{8-1.5}{120-20}[/tex]
[tex]m=\dfrac{6.5}{100}[/tex]
[tex]m=0.065[/tex]
Therefore, the rockets rate of change is 0.065 miles per seconds .

The property tax on a $60,000 home is $1,500. At this rate what will the property tax be on a home worth $75,000?
Answers
Answer:
The answer is $1,875
Step-by-step explanation:
1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750
2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000
3. So then $1,500 + $375 = $1,875
4. $75,000:$1,875

What would be the slope for a line perpendicular to y = -¼x + 2?
Answers
Answer:
m perpendicular= [tex]-\frac{1}{notlinear}[/tex]
Step-by-step explanation:
So if our slope is negative, the slope perpendicular to that would be the positive reciprocal.
Let m= -A/B so the slope perpendicular to that would be B/A
Here our slope is -1/4 so the slope perpendicular to that would be -(-4/1) which is just 4
Therefore your perpendicular slope would be 4

Al sumar su doble, su mitad y 15 se obtiene 99.
Answers
Answer:x = numero
2x= doble
x/2= mitad
sumamos todo : x+2x+x/2+15=99
7x/2= 99-15
7x= 84(2)
x=168/7
x=24
comprueba sumando 24+48+12+15=99 suerte!!!
Step-by-step explanation:
The value of the unknown number is 33.6
Let the unknown number be "x"
The half of the number is 0.5x
Double of the number is expressed as 2x
Adding this functions together and 15 and equating to 99 will give;
0.5x + 2x + 15 =99
Solve for x
2.5x = 99 - 15
2.5x = 84
x = 84/2.5
x = 33.6
Hence the value of the unknown number is 33.6

True or False? The blue radius is perpendicular to the green chord.
Answers
The statement that the blue radius is perpendicular to the green cord is false
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false
