Answer:
Step-by-step explanation:
to find percent you would simplify that fraction so that it’s a decimal (0.16) and multiply by 100 (16) and add a percent symbol so it would be 16%
basically the equation for finding percent would be
(x/y)100
We can notice that : Line Passes through the Points (1 , 2) and (4 , -4)
Let us find the slope of the line in order to write the Equation of the Line.
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
Points are (1 , 2) and (4 , -4)
here x₁ = 1 and x₂ = 4 and y₁ = 2 and y₂ = -4
Equation of the Line passing through (1 , 2) and having slope -2 is :
⇒ y - 2 = -2(x - 1)
⇒ y = -2x + 2 + 2
⇒ y = -2x + 4

Step-by-step explanation:
(a) Substitute t=2015 into the function:
p(t) = 1.32t - 2589.6
p(2015) = 1.32(2015) - 2589.6
p(2015) = 2659.8 - 2589.6
p(2015) = 70.2
So, there will be 70,200 people in 2015 who will be 100 years or older.
Substitute t=2025 into the function:
p(t) = 1.32t - 2589.6
p(2025) = 1.32(2025) - 2589.6
p(2025) = 2673 - 2589.6
p(2025) = 83.4
So, there will be 83,400 people in 2025 who will be 100 years or older.
(b) Substitute p(t)=100 into the function and solve for t:
p(t) = 1.32t - 2589.6
100 = 1.32t - 2589.6
2689.6 = 1.32t
2037.57 = t
2038 = t
Therefore, the number of people 100 years or older will reach 100,000 by 2038.

BCD
Step-by-step explanation:
Is that hegarty maths? Just curious. Anyway acute means a angle below 90
Answer:
Lines of latitude run in horizontal parallels and represent distance north or south from the equator, measured in an angle from the centre of the Earth. The equator represents 0° and each pole represents 90°
