Use the discriminant to determine the number and type of solutions the equation has.
x2 + 6x + 12 = 0
two rational solutions
two irrational solutions
no real solution
one real solution
Answer:
no real solutions
Step-by-step explanation:
x² + 6x + 12 = 0
the general solution :
x = (-b ±sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 6
c = 12
the discriminate is (b² - 4ac).
so,
x = (-6 ± sqrt(6² - 4×1×12))/(2×1)
the discriminate is
6² - 4×12 = 36 - 48 = -12
this is negative, so via the square root of a negative number we get 2 complex (imaginary) solutions.
Find the distance from point L to point M, if the point L has coordinates (-10,-9)
and the point M has coordinates (-2,6).
Answer:
The distance from point L to point M is 17
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is calculated as follows:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Point L has coordinates (-10,-9) and point M has coordinates (-2,6).
Calculate the distance between L and M:
[tex]d=\sqrt{(6+9)^2+(-2+10)^2}[/tex]
[tex]d=\sqrt{15^2+8^2}[/tex]
[tex]d=\sqrt{225+64}=\sqrt{289}[/tex]

24.4 > 24.34
Step-by-step explanation:
Tenth place value can be any number more than the tenth value in 24.34.
In the decimal number 24.34, the tenth value is 3. So, it should be more than 3
Options can be any one of these
24.4 or
24.5 or
24.6
Answer:
Values (tenths) that would make the number comparison 24._ > 24.34 true would be:

If h(x) = x" for some positive constant a, and
h(27x) = 3h(x) for all positive values of x, what is
the value of a ?
By using the natural logarithm, we will see that the value of a is 0.33
How to get the value of a?
We know that:
h(x) = x^a
And we know that:
h(27x) = 3h(x).
We can rewrite this as:
(27x)^a = 3*(x)^a
And remember that we can distribute exponents, so the left side can be rewritten as:
(27*x)^a = (27^a)*(x^a)
Then we have:
(27^a)*(x^a) = 3*(x)^a
This means that:
27^a = 3
Now remember the rule:
ln(x^n) = n*ln(x)
If we apply the natural logarithm to both sides, we get:
ln(27^a) = ln(3)
a*ln(27) = ln(3)
a = ln(3)/ln(27) = 0.33

When solving an ______, use inverse operations to undo the operations.
Answer:
equation
Step-by-step explanation:
Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.
[RevyBreeze]
Answer:
equation
Step-by-step explanation:
To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation. Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.

Terry calculates how much wood he needs to build the desk shown in the diagram . He says the area is 600ft2
What error did terry make
Find the correct area and explain your answer
Answer:
He forgot to multiply by 1/2 when finding the area of the above triangle.
Now we find the correct area;
A = BH x 1/2 (formula for finding area of triangle)
A = 10 x 24 x 1/2
A = 240 x 1/2
A = 240/2
A = 120
Now the rectangle's formula which is just (W x L) where "w" is the width and "l" is the length;
A = W x L
A = 24 x 15
A = 360
Now we add both the sums of the two areas:
120 + 360 = 480 square feet, the information provided here is your explanation.
After a successful Friday night at the local BDubs, 92% of the daily allocated wings were sold to restaurant-goers. The kitchen staff was a bit upset because that meant there were only 96 wings left between them to take home at the end of night. How many wings did BDubs start off with that night?
Answer:
88
Step-by-step explanation:
92% = 0.92
0.92(96) = 88.32
88 is rounded to the nearest wing
There were 20 balloons at the beginning of a party. By the end of the party,n of them had popped. using n, write an expression for the number of the balloons that were left
expression: 20 - n
total balloons = 20popped balloons = nnumbers of balloons left = total balloons - popped balloons
numbers of balloons left = 20 - n
Answer:
20 - n balloons remained
Explanation:
To find how much balloons remained after the party, we need to subtract the number of balloons popped from the total balloons.Finding how much balloons remained:
We know that there were 20 balloons at the beginning of the party and n balloons popped when the party was over.20 - n balloons remained.
Krystal Ball's pulse rate is 30% higher than its normal rate of 70bpm. What is her pulse rate? After
lying down it decreased 20%. What is her heart rate now?
Starting bpm = 91
Resting bpm = 72.8
=========================================================
Explanation:
A 30% increase is represented by the multiplier 1.30 because
100% + 30% = 1.00 + 0.30 = 1.30
So Krystal's initial heart rate is 1.30*70 = 91 bpm.
If you wanted, you can think of it like this
30% of 70 = 0.30*70 = 21 is added onto the initial 70 bpm to get 70+21 = 91 bpm.
-----------
To decrease by 20%, we use the multiplier 0.80 since
100% - 20% = 1.00 - 0.20 = 0.80
Losing 20% of something means we keep the remaining 80%
So,
80% of 91 = 0.80*91 = 72.8 bpm.
-----------
Here's one way to find the final bpm in one single line
1.30*0.80*70 = 72.8
in which you could write it like this
(1 + 0.30)*(1 - 0.20)*(70) = 72.8
The second way may be a bit longer, but I find it's more descriptive to see where the percentage increases vs percentage decreases are.
A stock rises in value from $20 to $40. Then it decreases in value from $40 to $20. Is the percentage increase from $20 to $40 the same as the percentage decrease from $40 to $20? Explain.
Answer:
No
Step-by-step explanation:
To find how much something is a percent of another number, divide it by said other number
20/40 = 0.5
0.5 × 100 = 50%
The first one is a 50% increase
Then, 40/20 = 2
2 × 100 = 200%
It is a 200% decrease
So no, because 50% doesn't equal 200%
Lucy makes 5 digit numbers using all these cards
3 4 6 7 9
how meny different numbers greater than 50,000 can she make
The selection of the 5-digit number illustrates arrangements
There are 1875 different numbers greater than 50000
How to determine the numbers?The digits of the 5 digit numbers are given as:
3 4 6 7 9
For the number to be greater than 50000, the first digit must be 6, 7 or 9 i.e. 3 numbers.
The other four digits can be any of the 5 numbers.
So, the count of numbers greater than 50000 is:
Count = 3 * 5 * 5 * 5 * 5
Count = 1875
Hence, there are 1875 different numbers greater than 50000
