Answer:
Lateral Surface Area = 94.25 cm²
Surface area = 150.8 cm²
Step-by-step explanation:
A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Step 1
We have to find the radius of the cylinder
We are told in the question that:
The circumference of one circle is 18.84 cm
Circumference of a circle = 2πr
18.84cm = 2πr
r = 18.84/2π
r = 2.9984791279cm
Approximately the radius = 3cm
Step 2
We find the Lateral Surface Area of the Cylinder
The formula =2πrh
r = 3cm
h = 5cm
=2×π × 3 × 5
= 94.24778 cm²
Approximately = 94.25 cm²
Step 3
We find the Surface Area of the Cylinder
The formula =2πr(r + h)
r = 3cm
h = 5cm
=2×π × 3 × 5(3 + 5)
= 150.79645 cm²
Approximately = 150.80 cm²

Answer:
60
Step-by-step explanation:
ez
Answer:
60
Step-by-step explanation:
to find the area of a trapezoid you do (a+b)/2 x h
so to find the area of yours you do (18+6)/2 x h
18 + 6 = 24
24 divided by 2 = 12
12 x 5 = 60

Which of those points does not lie on the line y = 3x + 5*
(1 Point)
O (1,8)
O (4, 17)
O (-2, 11)
0 (0,5)
Answer:
point (-2,11) does not lie on the given line
Step-by-step explanation:
To find : Which of the following points does not lie on the line ?
Solution :
To determine the point lie on line or not we have to put points in equation if it satisfy then it lie otherwise not.
a) Point (1,8)
Line y=3x+5
Substitute x=1 and y=8
8=3(1)+5
8=8
(1,8) point lie on the line.
b) Point (4,12)
Line y=3x+5
Substitute x=4 and y=17,
17=3(4)+5
17=12+5
17=17
(4,17) point does not lie on the line.
c) point (-2,11)
Line y=3x+5
substitute x=-2 and y=11
11=3(-2)+5
11=-6+5
11 is not equal to -1
d) Point(0.5)
Line y=3x+5
Substitute x=0 and y=5
5=3(0)+5
5=5

According to the US Census, the percent of residents aged 65 or older in the 50
states and District of Columbia has mean 13.26% and standard deviation of
1.67%. Find and interpret the standardized scoreſfor the state of Colorado, which
had 9.7% of residents age 65 or older. *
Answer:
z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean.
Step-by-step explanation:
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean

I need help im doing IXL right now (BB.3 Complete a function table: quadratic functions)
i just need help with this final question (posted with a picture)
Answer:
0, 2, 4
Step-by-step explanation:-2 + 2 = 0 + 2= 2 + 2 = 4
The function table is solved and the quadratic equation is f ( x ) = -3x²
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
f ( x ) = -3x²
when x = -2
f ( -2 ) = -3 ( -2 )²
f ( -2 ) = -12
And , when x = 0
f ( 0 ) = 0
when x = 2
f ( 2 ) = -12
when x = 4
f ( 4 ) = -48
Hence , the function table is f ( x ) = { -12 , 0 , -12 , -48 }

Hope it helps you in your learning process.
The triangle with no sides congruent and all angles less than 90° is called an acute scalene triangle option (C) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a statement:
A triangle with no sides congruent and all angles less than 90° is called a __________ triangle.
As we know, an acute scalene triangle is a triangle with no congruent sides and all angles smaller than 90 degrees.
Also,
A scalene triangle is one in which each side has a different measure.An isosceles triangle is one in which all sides are equal.An equilateral triangle is one in which all of its sides are equal.Thus, the triangle with no sides congruent and all angles less than 90° is called an acute scalene triangle option (C) is correct.
