Answer:
Step-by-step explanation:
1) if the point A has coordinates (-1;10) and the point B - (5;2), then it is possible to write common view of the required equation of the line:
2) if to substitute the coordinates of A&B into the common equation, then:
3) finally, in slope-intersection form:
3y= -4x+26; ⇔ y= -4/3 x +26/3.
P.S. the suggested way of the solution is not the only one.
Answer:
67.029 cm ³
Step-by-step explanation:
Volume of cone = ¹/³ πr²h
π= 3.142 , r = diameter /2 so r =2cm , height (h) = 16cm
so V = ¹/³ π x (4) x 16
V = 62.029cm³
Answer:
lesser x = -4
greater x = 1
Step-by-step explanation:
here's the solution :-
=》
=》
=》
=》
now, there are two cases
case 1) where x + 4 = 0
=》x = -4
case 2) where x - 1 = 0
=》x = 1
30 should be right ur welcome
Answer:
P = 300
r = 0.15
n = 12
A(t) = 300(1.0125)^12t
Step-by-step explanation:
Given that:
Total credit taken for book purchase = $300
Annual Interest rate = 15% compounded monthly
Time or period = 4 years
P(1 + r/n)^nt
P in the expression above means the principal amount which is the total credit spent on book purchase = $300
r = annual interest rate on Emma's account = 15% = 15/100 = 0.15
n = number of compounding times per period ; loan which compounds monthly = number of months in a year = 12
Hence,
P = $300 ; r = 0.15 ; n = 12
Substituting into the equation :
P(1 + r/n)^nt
Simplified expression written in terms of t:
Final amount, A after t years
A(t) = 300(1 + 0.15/12)^12t
A(t) = 300(1 + 0.0125)^12t
A(t) = 300(1.0125)^12t
