Which of the following formulas would you use in order to find the surface area of the solid figure below?
SA = r + r 2
SA = 4 r 2
SA =2 l + l 2
SA = 2 rh + 2 r 2
Answers
Answer:
SA = r (PI) + r (PI) 2
Step-by-step explanation:
The surface area of the solid figure would be; SA = πrl + πr²
What is the surface area of a cone ?The total surface area of a cone is given by:
The Surface area of the cone =[tex]\pi r(r+\sqrt{h^2+r^2} )[/tex]
where r is the radius of the cone, h is the height of the cone, l is the length of the cone
Since it is known that Right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
Length = [tex]\sqrt{h^2+r^2}[/tex]
Therefore, we can conclude that;
The total surface area of the cone is given by the following formula;
SA = πrl + πr²

The graph of which line intersects the graph of y + 10 = -5(x - 1) in only one point?
Answers
First, I’m going to the line is question into slope intercept form.
y + 10 = -5x + 5
y = -5x + 5 -10
y = -5x -5
y + 10 = -5 (x - 1) becomes y = -5x -5 in slope intercept form. I will call this line ‘line 1’
A becomes y = 5x -15 in slope intercept form
B becomes y = -5x + 25 in slope intercept form
C becomes y = -5x -5 in slope intercept form
D becomes y = -5x + 10 in slope intercept form
C is the same line as line 1. Any point that is on line 1 is also on line C, so C cannot be it.
Notice that line B and D have the same slope but different y-intercepts as line 1. That means these lines are parallel (not the same line though - different y intercepts) to line 1, so they will never intercept.
Line A has a different slope vs line 1, so they will eventually intersect only once
Find the slope that passes through the two points. (9,3) and (6,7)
Answers
Answer:
m=4/-3
Step-by-step explanation:
the equation for slope (m) when given two points is (y2-y1)/(x2-x1)
we are given the points (9,3) and (6,7)
we can label the points:
x1=9
y1=3
x2=6
y2=7
now substitute into the equation
m=(7-3)/(6-9)
subtract
m=4/-3
the slope is 4/-3

Given that, an equation, 3ˣ = 10, we need to find the solution of it,
So, solving for x,
3ˣ = 10
Taking log both sides,
㏒ 3ˣ = ㏒ 10
Since, ㏒ aⁿ = n ㏒ a
Therefore,
x ㏒ 3 = ㏒ 10
x = ㏒ 10 / ㏒ 3
x = 1/0.477
x = 2.095
x ≈ 2.1
Hence, the solution of the given equation is x = 2.1
