The population in a certain town is increasing linearly each year. The population at time t=3 is 1160 and at time t=5 is 1520, where t is the number of years after 1990
Answer:
1999
Step-by-step explanation:
The equation which represents the given situation is P=180t+620.
Given that, the population at time t=3 is 1160 and at time t=5 is 1520, where t is the number of years after 1990.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, the standard form of the population is increasing linearly is P = mt + b.
Where m is the slope = (y2-y1)/(x2-x1)=(1520-1160)/(5-3)
=360/2
=180
So, 1160=180 × 3 + b
⇒ 1160=540 × 3 + b
⇒ b=620
Then, the equation is P=180t+620
Therefore, the equation which represents the given situation is P(t)=180t+620.

b) Write the number 52100 as a power of 10.
Answer:
5.21 * 10^4.
Step-by-step explanation:
There are 4 more digits after the 5 so it is:
5.21 * 10^4.
[tex]52100 = 521 \times {10}^{2} = \\ [/tex]

If ΔABC = ΔDEF, angle m∠A = 50, and angle m∠E = 30, what is angle m∠C?
When you indicate triangle congruency, the order of the letters matter. As you see these statements, look at how the side length names correspond to how the letters are written in its order, ΔABC ≅ ΔDEF. (By the way, triangles aren't equal with an = sign. It's a ≅ congruency sign.)
AB is congruent or the same length as DE.
BC is congruent or the same length as EF.
AC is congruent or the same length as DF.
In the same way, all of the angles in the corresponding order are ALSO congruent. By the way, we say that angles are congruent and angle MEASURES (like 30 degrees) are equal.
m∠A = m∠D
m∠B = m∠E
m∠C = m∠F
In the same way, we can try to find m∠C, or measure C!
1. Let's find the missing angle!
So, we know that m∠A is 50 degrees and m∠E is 30 degrees. Since we know that m∠E = m∠B because of the order of the triangles, now we know two of the angles in triangle ABC.
m∠A = 50 degrees
m∠B = 30 degrees
m∠C = 180 degrees - (50 + 30) = 100 degrees
(We minus from 180 degrees because 180 degrees is the sum of the angles in a triangle!)
And that's it! If you have any questions, please feel free to ask questions. I'm not here to judge, and I'm only here to help. Again, ask questions if you need help. It's crucial that you know the basics of geometry!

Answer:
Rate of change for the second one (at the top) is 10
x- intercept is (-10,0)
y- intercept is (0,20)
Step-by-step explanation:
Answer:
in bold below
Step-by-step explanation:
Left Side
If we let the price be represented by p and the quantity by q, then a suitable equation is ...
p/30 +q/35 = 1 . . . . equation in intercept form
7p +6q = 210 . . . . . multiply by 210
p = -6/7q +30 . . . . solve for p
The slope is -6/7.
The "rate of change" is -6/7. (slope and "rate of change" mean the same)
The x-intercept is 35.
The number at the end is zero (35). (assuming "the end" is the right end of the graph)
The starting price is the y-intercept (30).
The rate of cost is the slope (-6/7).
__
Right Side
The cost starts at 20 and goes up 10 for each 5 games, so 2 per game. A suitable equation is ...
y = 2x + 20
The rate of change is 2.
The x-intercept is where y=0. It will be -20/2 = -10.
The y-intercept is 20.
_____
The graph has to do with games and cost, not minutes and feet. There is insufficient information to answer questions about minutes and feet.
_____
Comment on these questions
The notations "per billions" on the left graph cause it to make no sense whatever. The ideas of "starting" and "ending" are usually time- or sequence-related. The graph shows nothing to indicate time or sequence. The idea of "rate of cost" for TV's is nonsensical. (Cost is a rate: dollars per unit.)

Yolanda purchased stock for $7,000 and paid a 1.5% broker fee. She sold it for $6,325 and paid a 0.5% broker fee. Compute her net proceeds.
Answer:
$-748.38
Step-by-step explanation:
Net proceeds = Total cost of selling the stock - Total cost of purchasing the stock
Total cost of purchasing the stock = $7000 + ($7000 x 0.015) = $7105
Total cost of selling the stock = $6,325 + ($6,325 x 0.005) = $6356.63
Net proceeds = $6356.63 - $7105 = $-748.38
