What are the solutions to the quadric equation x^2-16=0
Answer:
x=4, x=-4
Step-by-step explanation:
x^2-16=0
Add 16 to both sides;
x^2-16+16=0+16
Simplify;
x^2=16
x=[tex]\sqrt{16}[/tex], x[tex]-\sqrt{16}[/tex]
[tex]\sqrt{16}[/tex]
=4
factor the number;16
[tex]\sqrt{4^2}[/tex]
=[tex]\sqrt{4}[/tex]
-[tex]\sqrt{16}[/tex]
Factor the number 16;
[tex]\sqrt{4^2}[/tex]
=-4
pls help me find the value of x!!!!
which answer would go with this problem (match the quadratic graph to an equation)
Answer:
Second (middle) option
Step-by-step explanation:
You can clearly tell from the graph that the y intercept is at 0,0
in [tex]ax^2+bx+c[/tex], c is always the y value of the y-intercept
in this case the value is 0 so there shouldn't be a visible "c" in the equation, which is why the answer is the middle option
Deandre is going bowling with some friends. He pays $5 to rent a pair of bowling shoes and $7 per game, g. If Deandre spent $26, how many games, g, did he play?
What is the equation the represents this situation and what is the amount of games that he played?
PLEASE HELP!
Answer:
3
Step-by-step explanation:
he spend 26 dollars and bought the shoes for 5 dollars
26-5=21 so therefore you have to divide the amount of money per game
26÷7=3
What is the value of s in the equation below? S + 1 1/2 = 10 1/2
Answer:
S=9
Step-by-step explanation:
10[tex]\frac{1}{2}[/tex] - 1[tex]\frac{1}{2}[/tex] = 9
Answer:
s=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
s+3/2=21/2
Step 2: Subtract 3/2 from both sides.
s+3/2−3/2=21/2−3/2
s=9
AD is the perpendicular bisector of BC.
BD = 5x – 10 and DC = 3x + 10.
Determine the value of x.
5x-10= 3x+10
5x-3x= 10+10
2x÷2= 20÷2
x= 10
Step-by-step explanation:
as AD bisects them they will be two equal parts so
5x-10=3x+10
5x-3x=10+10
2x=20
divide both sides by 2 and
x=10
Gravel is being dumped from a conveyor belt at a rate of 15 ft3/hr and its coarseness is such that it forms a pile in the shape of an inverted right cone whose height is three times its base radius. How fast is the height of the pile increasing when the pile has a height of 10 ft
Answer:
0.43 ft/hr
Step-by-step explanation:
dv/dt = 15ft³/hr
Height = 10ft
We are required to get dh/dt
h = 3r
r = h/3
Formula for volume = 1/3πr²h
We put value of h
1/3π(h/3)²h
= 1/3π(h²/9)h
= 1/3πh³/9
= πh³/29
dv/dt = 1/27π.3h²dh/dt
= dv/dt = πh²/9dh/dt
Remember dv/dt = 15
When we put this in we get
dh/dt = 15x9/3.142x10²
= 135/314.2
= 0.43 ft³/hr

At a park, 80 out of the 200 people there are men. The rest are women.
What percent of the people are women?
Answer: 3/5 of the park population is female, or 60 percent. How? 80:200 can be simplified to 40:100, and this in fraction form is 40/100. We can further simplify it by dividing both by 10 to get 4/10, and then by 2 to get 2/5. 5 - 2 = 3, so 3/5 is the answer.
I hope this helps!

Factorise the following.
Answer:
x²(9x– 11)(9x + 11)
Step-by-step explanation:
81x⁴ – 121x²
The expression can be factorised as follow:
81x⁴ – 121x²
x² is common to both term. Thus:
81x⁴ – 121x² = x²(81x² – 121)
Recall:
81 = 9²
121 = 11²
Therefore,
x²(81x² – 121) = x²(9²x² – 11²)
= x²[(9x)² – 11²]
Difference of two squares
x²(9x– 11)(9x + 11)
Therefore,
81x⁴ – 121x² = x²(9x– 11)(9x + 11)

Write an equation when Angle A and Angle B are vertical angles
Answer:
X + Y = 180°
Step-by-step explanation:
We know that vertical opposite angles are equal
So,
Angle A = Angle B
So,
Assume;
Angle A = x
So,
Angle A + Y = 180°
So,
X + Y = 180°

Line I is parallel to line m. If the
measure of 26 is 75°, what is the
measure of Z2?
1/2
4/3
5/6 = 75°
78
Answer:
75°
Step-by-step explanation:
All parallel lines will meet their transversal (the line going through them) at the same angle. We can imagine sliding line m up to line l until the two are overlapping, and naturally all of those angles at the intersection will overlap, too. ∠6 will overlap ∠2, so the two angles are congruent. If m∠6 = 75°, then m∠2 = 75°!

Answer:
x = 3
Step-by-step explanation:
Since, 2 is the arithmetic mean of 1-2x and 3x.
Therefore,
[tex] \frac{1 - 2x + 3x}{2} = 2 \\ \\ \frac{1 + x}{2} = 2 \\ \\ 1 + x = 4 \\ \\ x = 4 - 1 \\ \\ x = 3[/tex]
