Answer:
Step-by-step explanation:
Notice that the difference is in the y-intercept. The first equation has a y-intercept of 0 since y = 4x + 0, the second has a y-intercept of 1 since
y = 4x + 1. In other words, the graph is translated up 1 unit to cross at (0,1) instead of (0,0)
Triangle DEF is similar to triangle D'E'F'.Triangle D E F is rotated about point F and is shrunk to form triangle D prime E prime F prime. Which similarity transformation could map △DEF to △D'E'F'? dilation and reflection dilation and translation rotation and dilation rotation and reflection
Answer:
The answer is "Rotation and dilation".
Step-by-step explanation:
The rotation is a spatial movement, which maintains at least one stage. The dilation of a transition affects a figure's dimensions. The center, as well as a scale factor k, are required Which meaning k determines if the expansion is an expansion or a decrease, therefore the above choice is correct because it just rotated and dilated from its original form.

Step-by-step explanation:
A population of rabbits in a lab, p(x), can be modeled by the function p(x)=20(1.014)^x, where x represents the number of days since the population was first counted.
Answer:
(a) 20 represents the initial population and
1.014 represents 1 + % growth of rabbits each day
(b) Average Rate of change = 0.8
Step-by-step explanation:
P.S - The exact question is -
Given - A population of rabbits in a lab, p(x), can be modeled by
the function p(x)=20(1.014)^x, where x represents the number
of days since the population was first counted.
To find - (a) Explain what 20 and 1.014 represent in the context of
the problem.
(b) Determine, to the nearest tenth, the average rate of
change from day 50 to day 100.
Proof -
(a)
Given that the function p(x) is represented as
[tex]p(x) = 20(1.014)^{x}[/tex]
Here,
20 represents the initial population and
1.014 represents 1 + % growth of rabbits each day
(b)
Given,
[tex]p(x) = 20(1.014)^{x}[/tex]
When x = 50
[tex]p(50) = 20(1.014)^{50}[/tex] = 40.08000 ≈ 40.1
When x = 100
[tex]p(100) = 20(1.014)^{100}[/tex] = 80.32033 ≈ 80.3
Now,
Average Rate of change = [tex]\frac{p(100) - p(50)}{100 - 50}[/tex]
= [tex]\frac{80.3 - 40.1}{50}[/tex]
= [tex]\frac{40.2}{50}[/tex]
= 0.804 ≈ 0.8
⇒Average Rate of change = 0.8

Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.
40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees. Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees. The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.----------------------------------------------------------------------------------------------------------
1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.
2) 140 + x + x = 180 (equation)
140 + 2x = 1802x = 180 - 1402x = 40 x degrees = 20 degreesANSWER: x = 20 DEGREES
----------------------------------------------------------------------------------------------------------
1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.
2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle
of left triangle.
2) 70 + 40 + y = 180
110 + y = 180y = 180 - 110y = 70 degreesANSWER: y = 70 DEGREES
----------------------------------------------------------------------------------------------------------

Find the area of the shaded region. Use 3.14 for pi.
Answer:
The shaded region is [tex]353.25m^2[/tex].
Step-by-step explanation:
The area of a circle is defined by the multiplication of the square of its radius, or half its diameter, by pi, or simply [tex]A=\pi r^2[/tex].
15m is the radius of the large circle, and also the diameter of the smaller circles.
The area of the shaded region will be the subtraction of the area of the two smaller circles from the area of the larger circle.
As such:
[tex]A=\pi(15)^{2}-2(\pi(\frac{15}{2} )^{2})\\\\A=(3.14)(15)^{2}-2(3.14)(\frac{15}{2} )^{2}\\A=706.5-353.25\\A=353.25[/tex]
Answer:
353.25 m²Step-by-step explanation:
Shaded region is the difference in the area of the bigger circle and two smaller circles.
Radius of bigger circle = 15 mRadius of smaller circles = 15/2 = 7.5 mThe shaded area:
A = π(15²) - 2π(7.5²) = π(225 - 112.5) = 3.14(112.5) = 353.25 m²Which of the following is an equation of a line that is parallel to one whose equation is y = 5x - 3?
It’s cost $3.75 to by 3/4 of a pound of walnuts.How many pounds of walnuts can your purchase with $11.25
Answer:
9/4 pounds of walnut
Step-by-step explanation:
First we divide 11.25/3.75=3 so we would know how many 3/4 pounds are there. Then, we know there are 3-3/4 pounds of walnuts. Mulitply them, you will get 9/4
Are these proportional? And I need to show work sooo for example on the first question we did in class we wrote down
-3/1
-6/2=-3/1
-9/3=3/1
I hope I’m not asking for too much but I want to start off my trimester strongly.
Answer:
Step-by-step explanation:
If y is proportional to x,
y ∝ x
y = kx
k = [tex]\frac{y}{x}[/tex]
Here, k = Proportionality constant
For y = -8 and x = -4,
k = [tex]\frac{-8}{-4}[/tex]
k = 2
For y = -4 and x = -2
k = [tex]\frac{-4}{-2}[/tex]
k = 2
For all values of x and y proportionality constant = 2.
For x = 0 and y = 0,
If we graph a line passing through these points, the line will pass through the origin (No y-intercept).
And we know that any line passing through the origin represents the proportional relation between x and y variables.
Therefore, given table represents the proportional relation.

Calculate the area
Answer:
140 feet squared
Step-by-step explanation:
Let's do this step by step. First, let's find the area of the rectangle, which is 8 times 10. It equals 80. Next, do the trangle. 6 times 10 is 60. So, 60 plus 80 equals 140.
Answer:
area of rectangle =L*B
8*10=80ft^2
area of triangle=1/2b*h
h is 8 ft
1/2*6*8
3*8
24ft^2
total area is 80+24

Find the location of the center of a circle if the endpoints of the diameter are at (-10,
-5) and (8,4).
Answer:
(- 1, - [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
The centre is located at the midpoint of the diameter.
Using the midpoint formula , then
centre = [tex]\frac{-10+8}{2}[/tex], [tex]\frac{-5+4}{2}[/tex] ) = ( [tex]\frac{-2}{2}[/tex], [tex]\frac{-1}{2}[/tex] ) = (- 1, - [tex]\frac{1}{2}[/tex] )

pens and paper. Carmen bought 5 packs of paper and 3 packs
of pens for $36.60. Alicia bought 6 packd of paper and 6
packs of pens for $53.40. What is the price of one pack of

The prices for both the things are $4.95 and $3.95 respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
Given that,
The price for 5 packs of paper and 3 packs of pens is $36.60.
And, for 6 packs of paper and 6 packs of pens is $53.40.
Suppose the price of one paper pack be x and of pens be y.
Then, the given case can be written in terms of equation as,
5x + 3y = 36.60 (1)
6x + 6y = 53.40 (2)
Solve the equations by multiplying equation (1) by 4 and (2) by 2 and then subtracting as follows,
2(6x + 6y) - 4(5x + 3y) = 2 × 53.40 - 4 × 36.60
=> 12x - 20x = 106.80 - 146.40
=> -8x = -39.60
=> x = 4.95
Substitute x = 4.95 in equation (2) to get,
6 × 4.95 + 6y = 53.40
=> 6y = 53.40 - 29.70
=> y = 23.70/6
= 3.95
Hence, the prices of one pack of paper and one pack of pens are $4.95 and $3.95 respectively.
