Step-by-step explanation:
The equation expressing the number y of shopping centers in terms of the number x of years after 1992 will be LINEAR in nature
The standard equation is expressed as;
y = mx+c
m is the slope
c is the intercept
If in 1992, there were 41,984 shopping centers in a certain country and in 2002, there were 48,225 we can express this as coordinate points
(0, 41984) and (10, 48,225)
Get the slope
m = 48,225-41,984/10-0
m = 6241/10
m = 624.1
Get the intercept, substitute m = 624.1 and the point (0,48225) into the formula y = mx+c
48225 = 624.1(0)+c
48225 = 0+c
c = 48225
Get the required equation
y = 624.1x+48225
Given: AE= 7 5/8cm, AB=BC, CD= 1/2cm, and DE is 3/8 more than AB. What is the length of DE?
Answer:
Length of DE = 2.90 (Approx)
Step-by-step explanation:
Given:
AE = 7[tex]\frac{5}{8}[/tex]cm = 61 / 8 cm = 7.625 cm
AB = BC
CD = 1/2 cm = 0.5 cm
DE is 3/8 more than AB
Find:
Length of DE
Computation:
Assume;
AB = BC = x
So,
DE = x + 3/8(x) = [11 / 8]x = [1.375]x cm
AE = AB + BC + CD + DE
7.625 = x + x + 0.5 + [1.375]x
7.125 = 3.375 x
x = 2.1111 (Approx)
Length of DE = [1.375][2.111]
Length of DE = 2.90 (Approx)

Step-by-step explanation:
Enter the equation of the line in slope-intercept form.
The line passes through (1.4) and (3,18).
The equation of the line is
Answer: y = 7x - 3
graphed equation attached
Step-by-step explanation: Slope-intercept form . y= mx+b
m is the slope, b is the constant, the y-intercept.
First find the slope: rise/run
Rise is the difference in y-values 18-4 = 14
Run is the difference between x-values 3 - 1 = 2
The Slope is 14/2 simplify:
m = 7
Use this calculated slope with values of y and x from either of the given coordinates and calculate b
y = mx + b
18 = 7(3) + b
18 = 21 + b . subtract 21 from both sides 18 - 21 = 21 -21 + b
-3 = b
Put these calculated values for m and b into the slope-intercept equation"
y = 7x - b

Step-by-step explanation:
A line is represented by the equation y/x−2=3/11 . Select all the coordinates of points that lie on the line.
A. (−163, −2)
B. (0, 2)
C. (5, 911)
D. (0, 611)
To determine the answer, we must graph each point and the line.
According to this graph, the point that lies on the line is B. (0, 2).
*Note: the line shown on the graph is [tex]y = \frac{3}{11}x + 2[/tex], which is the equivalent of the one in the question. All I did was solve the equation for y to convert it to slope-intercept form.

(ASAPPP) The position of an object at time t is given by s(t) = -2 - 6t. Find the instantaneous velocity at t = 2 by finding the derivative.
Answer:
The instantaneous velocity at [tex]t = 2[/tex] is [tex]-6[/tex].
Step-by-step explanation:
We have the position as the function
[tex]s(t) = -2 - 6t[/tex]
As we know that the velocity is the rate of change of position over time, so it is basically the derivative of the function.
so finding the derivate of [tex]s(t) = -2 - 6t[/tex]
∴ [tex]s'(t)=-6[/tex]
The instantaneous velocity at [tex]t = 2[/tex]
[tex]s'(2)=-6[/tex]
Therefore, the instantaneous velocity at [tex]t = 2[/tex] is [tex]-6[/tex].
Please note that the negative value indicates the direction of movement, in this case, it would be backward.
Rosa is looking at a map of the park that is laid out on a coordinate plane. Rosa is at(1, -1). The shelter house is at (-2, -4) and the fossil exhibit is at (3, 2). Each unit on the map represents 100 feet. How much closer is rosa to the fossil exhibit than to the shelter house
Answer:
[tex]63.709feet[/tex]
Step-by-step explanation:
This deals with the distance between two pointsuse the equation [tex]distance=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}[/tex] So we do the follow stepsFind distance from Rosa to Shelter houseFind distance from Rosa to Fossil exhibitSubtract the two answers to see differenceSo distance from Rosa to Shelter, we use (1,-1) and (-2,-4) so you plug your points in as follows [tex](1,-1)=(x_1,y_1)[/tex] and [tex](-2,-4)=(x_2,y_2)[/tex] so then[tex]distance=\sqrt{((-2)-(1))^{2}+((-4)-(-1))^{2}}\\ distance=\sqrt{(-3)^{2}+(-3)^{2}}\\ distance=\sqrt{9+9}\\ distance=\sqrt{18}=4.24264[/tex] approximately (round off as they require)Now putting that into feet [tex]4.24264*100feet=424.264feet[/tex] Then next, distance from Rosa to Fossil exhibit, we use (1,-1) and (3,2) so you plug your points in as follows[tex]distance=\sqrt{((3)-(1))^{2}+((2)-(-1))^{2}}\\ distance=\sqrt{(2)^{2}+(3)^{2}}\\ distance=\sqrt{4+9}\\ distance=\sqrt{13}=3.60555[/tex] approximately (round off as they require)Now putting that into feet [tex]3.60555*100feet=360.555feet[/tex] So right away we know, Rosa is closer to the Fossil exhibit than the ShelterThen to know by how much we subtract the longer distance from the shorter so [tex]424.264feet-360.555feet=63.709feet[/tex]Rosa is closer to fossil exhibit than shelter house.
What is Distance Formula?The two points in the cartesian plane P(a, b) and Q(c, d) then the distance between P and Q is
PQ = √c-a )² + (d-b)²
The distance from Rosa to shelter house
d= √(-2-1)² + (-4 +1)²
d =√9 + 9
d = √18
d = 4.24
and, the distance from Rosa to fossil exhibit
d= √(3-1)² + (2+1)²
d =√4 + 9
d= √13
d= 3.6
