Help I do not know how to do this!
Step-by-step explanation:
this is one of the formulas you should remember for life :
the general solution for a quadratic equation
ax² + bx + c = 0
is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case that is
x = (-4 ± sqrt(4² - 4×1×-1))/(2×1) = (-4 ± sqrt(16 + 4))/2 =
= (-4 ± sqrt(20))/2 = (-4 ± sqrt(4×5))/2 =
= (-4 ± 2×sqrt(5))/2 = -2 ± sqrt(5)
x1 = -2 + sqrt(5) = 0.236067977...
x2 = -2 - sqrt(5) = -4.236067977...
so, the negative solution is the x2 solution :
-4.236067977...
I don't know to how many decimal positions you are supposed to round. it is not specified in your problem definition.

What are all the real zeros of y=(x-20)^2 +5
Please show step by step I'm so lost
Simplify
[tex]\\ \rm\longmapsto y=(x-20)^2+5[/tex]
[tex]\\ \rm\longmapsto y=x^2-40x+405[/tex]
Graph attached
No real zerosAnswer:
no real zeros
Step-by-step explanation:
We are given the following quadratic function:
[tex]y = {(x - 20)}^{2} + 5[/tex]
firstly simplify it to standard form which is
[tex]y = {x}^{2} -40x + 405[/tex]
To figure out the real zeros, set y to 0:
[tex] {x}^{2} - 40x + 405 = 0[/tex]
recall that,a quadratic equations has real zeros in case its discriminant is greater than or equal to 0, therefore
b²-4ac≥0⇒real rootsconsider,
a=1b=-40c=405now substitute:
[tex] { (- 40)}^{2} - 4(1)(405) \stackrel{ ? }{ \geq}0[/tex]
simplifying yields:
[tex] 1600 - 1620 \stackrel{ ? }{ \geq}0 \\ - 20 \ngeq 0[/tex]
hence, The function has no real zeros
Identify the property that justifies the statement.
23. 614 = 614
24. If a = b and b = c, then a = c.
Answer:
23. Reflexive property
24. Transitive property
Step-by-step explanation:
In algebra, the reflexive property of equality states that a number is always equal to itself. Reflexive property of equality. If a is a number, then a = a
The Transitive Property states that for all real numbers x ,y, and z, if x=y and y=z , then x=z .

Find the circumference of the circle
Answer:50.3m
Step-by-step explanation:
Answer:
50.24 m[tex] \\ [/tex]
Step-by-step explanation:
To find the circumference of the circle, we must know this formula
[tex]\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: \: Circumference_{(circle)} = 2 \pi r}}}}}} \: \: \bigstar \\ \\ [/tex]
Where,
r denotes the radius of the circle. Here, the radius is 8 mWe'll take the value π as 3.14With the help of this formula, we can find the circumference of the circle.
[tex] \\ [/tex]
Now, we'll substitute the values in the formula :
[tex] \\ { \longrightarrow \qquad{ \sf{ \: \: Circumference_{(circle)} = 2 \times 3.14 \times 8}}} \: \: \\ \\ [/tex]
[tex]{ \longrightarrow \qquad{ \sf{ \: \: Circumference_{(circle) }= 3.14 \times 16 }}} \: \: \\ \\ [/tex]
[tex]{ \longrightarrow \qquad{ \pmb{ \frak { Circumference_{(circle) }= 50.24\: }}}} \: \: \\ \\ [/tex]
Therefore,
The circumference of the circle is 50.24 mSolve for x round to the nearest tenth

A karate studio charges $35 for the first course and $22. 50 for each course after that, even if the student leaves the course early. Cena paid $170 for her son to take courses. How many courses did he take? 6 courses 7 courses 8 courses 10 courses.
The Cena can take 7 courses
We have given that the karate charges $35 for the first course and $22.50 for each course after that. Our total is $170.
What is the condition we can write here?[tex]22.50x + 35 = 170[/tex]
for solving this linear equation
First, subtract 35 from both sides.
[tex]22.50x = 135[/tex]
isolate x so divide both sides by 22.50.
[tex]x=\frac{135}{22.50}[/tex]
Therefore we get x = 6
Remember to add the additional class, so x is actually 7.
So,the Cena can take 7 courses.

ANYONE GOOD AT MATH NEED HELP ON THIS QUESTION?!!
TOPIC: Compound Probability
Bernardo Flips a coin and rolls a 1-6 number cube. Draw a tree diagram to show the set of all possible outcomes.
Answer:
There are a total of twelve possible outcomes. This is because flipping a coin has two possible outcomes (either heads or tails) and rolling a number cube has 6 of them (1-6) so 2 times 6 is 12.
If you want to draw a tree diagram, first split your tree into two branches, one for heads and one for tails. Then, split both branches into 6 sub-branches each, so each branch has a full set of numbers from 1-6.
Or you can do it the other way around, first split your tree into 6 branches, then split all branches into 2 sub-branches each.
