Answer:
x=10.29, x=-0.29
Step-by-step explanation:
Given data
x^2- 10x - 3 = 0
a=1
b=-10
c=-3
substitute into the following expression we have
x=(-b±√(b²-4ac))/(2a)
x=(-(-10)±√((-10)²-4*1*-3))/(2*1)
x=10±√100+12))/(2)
x=10±√112))/(2)
x=10±10.58/(2)
x=10+10.58/(2) , x=10-10.58/(2)
x=20.58/(2) , x=-0.58/(2)
x=20.58/2, x=-0.58/2
x=10.29, x=-0.29

Given that a - b = 3 and ab=5, find, without the use of a calculator,
the value of a +b?
Answer:
√29
Step-by-step explanation:
We are here given that ,
a - b = 3 ab = 5 .Now square the first equation ,
⇒ a - b = 3
⇒ ( a - b)² = 3²
⇒ a² + b² - 2ab = 9
⇒ a² + b² - 2(5) = 9
⇒ a² + b² -10 = 9
⇒ a² + b² = 9 + 10
⇒ a² + b² = 19
Adding 2ab both sides ,⇒ a² + b² + 2ab = 19 + 2(5)
⇒ (a + b)² = 19 + 10
⇒ ( a + b)² = 29
⇒ a + b = √29 .
The perimeter of a rectangle is 202020 centimeters. The length is 666 centimeters. What is the area of the rectangle?
Answer: 24 cm²
Step-by-step explanation:
To find the area, first find the width of the rectangle.
Perimeter = (2 * Length) + (2 * Width)
20 = (2 * 6) + (2w)
20 = 12 + 2w
2w = 20 - 12
w = 8/2
w = 4 centimeters
Area = Length * Width
= 6 * 4
= 24 cm²
The rectangle below has an area of x ^ 2 - 16 square meters and a width of x + 4meters . What expression represents the length of the rectangle?
Answer:
length=x-4

Simplify 2x^2-7x-4/x^2-5x+4 What are the excluded values
Answer:
x = 1
Step-by-step explanation:
Given
[tex]\frac{2x^2-7x-4}{x^2-5x+4}[/tex] ← factor numerator and denominator
= [tex]\frac{(x-4)(2x+1)}{(x-4)(x-1)}[/tex] ← cancel (x - 4) on numerator/ denominator
= [tex]\frac{2x+1}{x-1}[/tex]
The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
x - 1 = 0 ⇒ x = 1 ← excluded value

Find the volume of the cylinder
What is the exact volume in terms ofx?
What is the approximate volume using 3 14 forx?
9514 1404 393
Answer:
5000π mm³ ≈ 15,700 mm³
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr²h
For the given radius and height, the volume is ...
V = π(10 mm)²(50 mm) = 5000π mm³
Using 3.14 for π, the volume is ...
5000(3.14) mm³ = 15,700 mm³

Answer:
Step-by-step explanation:
2n = 3n - 5
This works out to n = 5.
The translates of ''Twice a number is five less than three times the number" as,
⇒ 2 x = 3 x - 5
Here,
The written expression is,
''Twice a number is five less than three times the number" .
What is Mathematical expression?
An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.
Now,
The written expression is,
''Twice a number is five less than three times the number" .
Let a number is ' x '.
Then, in mathematical expression it can be written as,
⇒ 2 x = 3 x - 5
After solving this, we get;
2 x = 3 x - 5
x = 5
So, The translates of ''Twice a number is five less than three times the number" as,
2 x = 3 x - 5

Michelle will sell her homemade necklaces for $8 each at a craft fair. It costs her $150 for the booth rental at the craft fair.
She made 200 necklaces to sell.
Part B Michelle wants to graph the equation for her profit from selling her necklaces. The y-intercept of this graph will be
her profit from selling none of her necklaces.
What is the y-intercept of the graph of the equation that represents Michelle's profit from selling her necklaces?
Answer:
The y-intercept is y = -$150
Step-by-step explanation:
We know that:
Each necklace is sold for $8.
The total cost for Michelle is $150.
The profit equation is:
Profit = Revenue - Cost.
We already know that Cost = $150
The revenue will depend on x, the number of necklaces sold, so if each one costs $8, and she sells x of them, the revenue is:
Revenue = $8*x
Then the profit, as a function of x, is:
y = P(x) = $8*x - $150
Where y represents the profit.
Now we want to find the y-intercept of the profit equation, where the y-intercept is the y-value when we use x = 0
Then the y-intercept is:
P(0) = $8*0 - $150 = -$150
Also the graph of the equation can be seen below, where you need to remember that x can be any value in [0, 200] and only can be an integer.
So you only need to graph the line between x = 0 and x = 200.

If \orange{\angle ADC}∠ADCstart color #ffa500, angle, A, D, C, end color #ffa500 measures 23^\circ23 ∘ 23, degrees, what does \blue{\angle ABC}∠ABCstart color #6495ed, angle, A, B, C, end color #6495ed measure?
Answer:
23 degrees
Step-by-step explanation:
First add a diameter. The triangle \pink{ABD}ABDstart color #ff00af, A, B, D, end color #ff00af is isosceles as \pink{AB}ABstart color #ff00af, A, B, end color #ff00af and \pink{BD}BDstart color #ff00af, B, D, end color #ff00af are radii, so must be equal. Therefore, \pink{\angle{BAD}}∠BADstart color #ff00af, angle, B, A, D, end color #ff00af and \orange{\angle{ADB}}∠ADBstart color #ffa500, angle, A, D, B, end color #ffa500 are equal. Since, the angles in a triangle sum to 180^\circ180 180∠ABD+∠BAD+∠ADB∠ABD+2⋅∠ADB∠ABD===180∘180∘180∘−2⋅∠ADB
So, \blue{\angle{ABE}} = 2 \cdot \orange{\angle{ADB}}∠ABE=2⋅∠ADBstart color #6495ed, angle, A, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, A, D, B, end color #ffa500. We can also create an isosceles triangle, \pink{BCD}BCDstart color #ff00af, B, C, D, end color #ff00af.Using the same argument we can find that, \blue{\angle{CBE}} = 2 \cdot \orange{\angle{CDB}}∠CBE=2⋅∠CDBstart color #6495ed, angle, C, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, C, D, B, end color #ffa500.∠ABC=∠ABE−∠CBEstart color #6495ed, angle, A, B, C, end color #6495ed, equals, start color #6495ed, angle, A, B, E, end color #6495ed, minus, start color #6495ed, angle, C, B, E, end color #6495ed
\orange{\angle{ADC}} = \orange{\angle{ADE}} - \orange{\angle{CDE}}∠ADC=∠ADE−∠CDEstart color #ffa500, angle, A, D, C, end color #ffa500, equals, start color #ffa500, angle, A, D, E, end color #ffa500, minus, start color #ffa500, angle, C, D, E, end color #ffa500
Hint #1010 / 11
Since \blue{\angle{ABE}} = 2 \cdot \orange{\angle{ADE}}∠ABE=2⋅∠ADEstart color #6495ed, angle, A, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, A, D, E, end color #ffa500 and \blue{\angle{CBE}} = 2 \cdot \orange{\angle{CDE}}∠CBE=2⋅∠CDEstart color #6495ed, angle, C, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, C, D, E, end color #ffa500, \blue{\angle{ABC}} = 2 \cdot \orange{\angle{ADC}}∠ABC=2⋅∠ADCstart color #6495ed, angle, A, B, C, end color #6495ed, equals, 2, dot, start color #ffa500, angle, A, D, C, end color #ffa500

Answer:
A. About 1/3 of the people prefer pie without ice cream
Step-by-step explanation:
We know there were 80 people surveyed, so that's our denominator. Pie without ice cream is the bottom row. 15 + 12 = 27. 27/80 = 0.3375, which is 33.75% (multiply 0.3375 by 100), which is about 1/3.
B is wrong, because the blueberry pie numbers are not double the cherry pie numbers
C is wrong because cherry with ice cream is 24, blueberry without is 15
D is wrong because the ratio of blueberry to cherry is 44:36, and with ice cream to without is 53:27
