pls help me someone, I’d appreciate it
Answer:
since A is getting smaller it cant be the last 2, so its either 1/2 or 3/4 and a 1/2 dilation would be wayy smaller than that. so I'm thinking its 3/4

an initial population of 327 pheasant increases at an anual rate of 15% write an exponential function to model the quail population
Answer:
y= 327(0.85)^t
Step-by-step explanation:
Given data
Initial Population= 327
Increase= 15%
The model for an exponential function is represented as
y= P(1-r)^t
Substitute
y=327(1-0.15)^t
y= 327(0.85)^t
Graph the equation using the point and the slope.
y-4= 1/2(x-4)
Answer:
Look at the explanation
Step-by-step explanation:
From this equation, we know our point slope form: y-4= 1/2(x-4)
From here, we also know our point: (4,4)
Our slope is 1/2
We first plot (4,4) on the graph. Then we graph the slope by moving one space up from (4,4) and moving over two spaces.
Our graph would look something like this:

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

I need help plzzzzzzz help24+4x=6x+2
Answer:
x = 11
Step-by-step explanation:
24+4x=6x+2
substract 2x from both sides 4x-4x and 6x -4x
24 = 2x + 2
Substract 2 from both sides 24-2 and 2-2
22 = 2x
Divide by 2 to both sides 22/2 and 2x/2
x = 11

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

An architect designs two similar triangular patios. The first patio has angle measures of (x + 5)°, (y + 15)°, and 80°. The second patio has angle measures of (x + 25)°, 40°, and 60°. Find the values of x and y. please answer fast! i just need this one!
Answer:
x = 55° and y = 25°
Step-by-step explanation:
Since we have two triangular patios with angles (x + 5)°, (y + 15)°, and 80° and the second patio has angles, (x + 25)°, 40°, and 60° respectively, and the sum of angles in a triangle is 180, we have that,
(x + 5)° + (y + 15)° + 80° = 180° and
(x + 25)° + 40° + 60° = 180°
Simplifying both expressions, we have
x + 5° + y + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
collecting like terms, we have
x + y + 5° + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
Adding the like terms, we have
x + y + 100° = 180° and
x + 125° = 180°
So,
x + y = 180° - 100° and
x = 180° - 125°
Thus,
x + y = 80° and
x = 55°
So, y = 80° - x = 80° - 55° = 25°
So, x = 55° and y = 25°
Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).
Plz help me someone
Answer:
(x+1)²+(y-2)² = 25
Step-by-step explanation:
Standard equation of the circle is expressed as;
(x-a)²+(y-b)² = r²
(a,b) is the center of the circle
r is the radius
Get the radius
r = √(x2-x1)²+(y2-y1)²
r = √(2+1)²+(6-2)²
r = √3²+4²
r = √9+16
r = √25
r = 5
Substitute into the formula
(x-a)²+(y-b)² = r²
a = -1, b = 2, r = 5
(x-(-1))²+(y-2)² = 5²
(x+1)²+(y-2)² = 25
This gives the required equation

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

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

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.
