Find the discriminant and determine the number of real roots for each equation. Show steps.
-9x^2 + x - 7 = 0
Answer:
0 real roots
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then the roots are not real
- 9x² + x - 7 = 0 ← is in standard form
with a = - 9, b = 1, c = - 7 , then
b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251
Since b² - 4ac < 0 then the equation has no real roots
what is the sum of the measures of the angles of a convex quadrilateral? will this property hold if the quadrilateral is not convex?
Answer:
The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.
Which of the following is a one-to-one functions?
Answer:
A function f : X → Y is said to be one to one (or injective function), if the images of distinct elements of X under f are distinct, i.e., for every x1 , x2 ∈ X, f(x1 ) = f(x2 ) implies x1 = x2 . Otherwise, it is called many to one function.

What is the answer.. to this !
Answer:
A = 3.14
Step-by-step explanation:
A = π[tex]r^{2}[/tex]
A = 3.14 x [tex]1^{2}[/tex]
(diameter = 2)
(remember, radius is half of the diameter)
(radius = 1)
A = 3.14

the function of C gives the percentage of homes using only cell phone service X years after 2004 explain the meaning of each statement.
1. C(10)=35
2. C(x) = 10
3. how is C(10) different from C(x) = 10?
Answer:
Step-by-step explanation:
1. C(10)=35 is the percentage of homes using only cell phone service 10 years after 2004, that is, after 2014.
2. C(x) = 10 is the percentage of homes using only cell phone service x years after 2004. We must find x.
3. how is C(10) different from C(x) = 10?
In C(10), 10 measures time in years and is the independent variable here; C10) is the dependent variable. See (2), above. In C(x), x is the (unknown) independent variable, whereas 10 is the output vaue, the dependent variable.

Write the fraction or mixed number as a percent (7/20)
Answer:
it would be 35% and as a decimal its 0.35
Step-by-step explanation:
hope that helps
Answer:
35%
Step-by-step explanation:
7/20 = 35/100 (you multiply by 5)
35/100 = 35%
A rectangle is 6 feet long and 4 feet wide. If each dimension is increased by the same number of feet, a new rectangle is formed whose area is 39 square feet more than the area of the original rectangle. By how many feet was each dimension increased?
Answer:
Each dimension increased by 3 ft.
Step-by-step explanation:
Area of the original rectangle = 4 * 6 = 24 square feet
Increased dimension = x ft
New length = 6 + x
New width = 4 +x
New area = (6 + x)(4 +x) {Use FOIL method}
= 6*4 + 6*x + x*4 + x*x
= 24 + 6x + 4x + x²
= x² + 10x + 24
New area = 24 + 39
x² + 10x + 24 = 63
x² +10x + 24 - 63 = 0
x² + 10x - 39 = 0
x² + 13x - 3x - 3*13 = 0
x (x + 13) - 3(x + 13) = 0
(x + 13)(x -3) = 0 {Ignore x + 13, as it gives negative value}
x - 3 = 0
x = 3

Hayley took a total of 9 quizzes over the course of 3 weeks.After attending 7 weeks of school quater,how many quizzes will hayley have taken in total
Answer:
21 quizzes
Step-by-step explanation:
3 quizzes per week 9÷3=3
7 weeks = 3×7 so 21 quizzes
Answer:
21 quizzes
Step-by-step explanation:
What we know:
- Hayley takes 9 quizzes in 3 weeks
What we want to find:
- The number of quizzes Hayley would've taken after 7 weeks
We need to first find the number of quizzes Hayley would take in 1 week and then multiply that number by 7. To find the number of quizzes per week, divide 9 by 3:
9÷3=3
Therefore, every week, Hayley takes 3 quizzes.
Now, we multiply 3 by 7:
3×7=21
Therefore, after attending 7 weeks of school, Hayley would've taken 21 quizzes in total.
I hope this helps!

Sally would like to have an average of 92 in her math class. She has completed four assignments with the following grades: 88, 97, 91, 86. What is the lowest grade Sally will need to make on the last assignment to meet her goal?
Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5
This would get of / 5 so you don't need to divide by 5
362 + x = 460
Subtract 362 from each side
x = 98
if n is an integer, what is the sum of the next three consecutive even integers greater than 2n? a. 6n + 12 b. 6n + 10 c. 6n + 4 d. 6n + 8
Answer:
a) 6n + 12
Step-by-step explanation:
Next three consecutive integers are : 2n + 2 , 2n + 4 , 2n + 6
2n + 2 + 2n +4 +2n +6 = 2n+ 2n + 2n + 2 + 4 + 6
= 6n + 12
The distance from Earth to Pluto is about 5,750,000,000 km. How many light-years is this?
Answer:
The average distance between Earth and Pluto is same as average distance of Pluto from the Sun. This is 0.000628 light years, nearly.
Explanation:
The average distance obetween two planets is nearly the average distance of the outer planet from the Sun. Earth is inner to Pluto. Average Sun-Pluto distance = 5906.4 million km. Divide by 149597870 to get distance in Au. Further divide by 62900 to get distance in ly.
