Answer:
What is f(x) + f(x) + f(x)? 3f(x)
3f(x) = 3x^2
Evaluate 3f(2) = 12
The required value of the additions of the functios is 3x².
Given that,
f(x) = x2
What is fx) + f(x) + f(x) is to be determined,
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax + b is a polynomial.
Here,
f( x ) = x²
Now f(x) +f(x) + f(x) = x² + x² + x²
f(x) +f(x) + f(x) = 3x²
Thus, The required value of the additions of the functions is 3x².

What is the area of this figure? Use 3.14 for pi.
A. 4.5 mm2
B. 9 mm2
C. 11.56 mm2
D. 18.61 mm2
Answer:
Step-by-step explanation:
area of triangle = 1/2 * base * height = 1/2 * 9 = 9/2
area of semicircle = 22/7 * {3 root 2 / 2}^2 = 22/7 *18 / 4 = 22/7 *9/2 = 198/14=99/7
area of figure = 99/7 + 9 /2 =18.6mm2
mark me as the brainliest
Answer:
area of figure= area of semi circle + area of triangle
area of semi circle= 1/2πr²
1/2×3.14×2.12×2.12
1/2×14.11
= 7.06
area of triangle = 1/2×base×height
but I am going to use the Pythagoras theorem to find the its height
= hypotenus² = base²+height²
3²=2.12²+h²
9=4.5+h²
9-4.5=h²
√4.5=√h²
h= 2.12
so area of triangle= 1/2×4.24×2.12
=4.5
area of figure = 70.6+4.5
= 75.1mm²

Find the area of the shaded region below.
All shapes in the figures are regular polygons.
PLSS HELP
Answer:
Step-by-step explanation:
We have 2 hexagons there, so we need to use the area formula for the large hexagon - the area of the small hexagon. As long as both of these are regular (and they are), we will use the formula
[tex]A=\frac{1}{2}ap[/tex]
where a is the apothem and p is the perimeter of the hexagon. We'll start with the large one first.
Note that a hexagon has 6 central angles that are all equivalent in degree. 360 / 6 = 60 degrees. Each of those 6 triangles has a vertex angle of 60. If we extract one of those triangles and then cut it in half by dropping an altitude from the vertex angle to the base of the triangle, we get a right triangle. The vertex angle is 30, one base angle is 90 and the other is 60. The height of this right triangle is the apothem, for which we want to solve. Using right triangle trig,
[tex]tan(60)=\frac{a}{7}[/tex] The 7 comes from the fact that when we split the triangle in half by dropping an altitude, we not only split the vertex angle in half, we also split the base length in half...from 14 to 7. Continuing,
7 tan(6) = a and
a = 12.124
Filling in the area now for the large hexagon:
[tex]A=\frac{1}{2}(12.124)(84)[/tex] {the perimeter is 6 sides times a length of 4 per side} and
A = 509.208
Now for the small hexagon. We'll do the same thing...extract a triangle and cut it in half by dropping an altitude and solving for a which is the height of the triangle. This half triangle has a base of 3 (half of 6).
3 tan(60) = a and
a = 5.196
Filling in the area now for the small hexagon:
[tex]A=\frac{1}{2}(5.196)(36)[/tex] and
A = 93.528
Now subtract the smaller area from the larger:
509.208 - 93.528 = 415.68
Does anyone know this ??
Answer:
A
Step-by-step explanation:
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]
Rationalise the denominator by multiplying numerator/ denominator by [tex]\sqrt{34}[/tex]
sin x = [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{\sqrt{34} }{\sqrt{34} }[/tex] = [tex]\frac{3\sqrt{34} }{34}[/tex] → A

A jewelry store received 16 inches long, 10 inches wide, 12 inches high. The package contains 1-inch cube that each hold one ring. How many rings did the jewelry store receive? Explain how you found your answer.
Answer:
1920 rings
Step-by-step explanation:
We need to simply find the volume of the package and the volume of the cube and then divide the volume of the package by the volume of the cube.
The package is a rectangular prism. The volume of a rectangular prism is:
V = L * W * H
where L = length
W = width
H = height
The volume of the package is:
16 * 10 * 12 = 1920 [tex]in^3[/tex]
The volume of a cube is:
V = L^3
where L = length of side
The volume of the cube is:
V= 1^3 = 1 [tex]in^3[/tex]
The number of rings the jewelry store received is:
1920 / 1 = 1920 rings

given a force of 10 N and an acceleration of 5 m/s 2. What is the mass ?
Answer:
2 kg.
Step-by-step explanation:
F = m * a (Newton's Second Law of Motion).
10 = m * 5
The mass m = 10/5 = 2 kg.
Solution,
Here,
Given,
Force= 10N
Acceleration= 5m/s^2
Mass= ?
Therefore, as we know that
Force= Mass× Acceleration
10=M×5
10/5= M
Therefore, M= 5kg.

Answer:
Amy will need to read 1 page each day.
Step-by-step explanation:
Total number of page of the magazine = 137 pages
Read pages of the magazine = 42 pages
Remaining pages to be read = 137 pages - 42 pages = 95 pages
She spends 10 days reading the same number of pages each day until she finishes.
The number of pages read in each of the 10 days = 95 pages / 10 days
= 9.5 pages
In 10 days Amy reads 9.5 pages
In a day she reads ?
10 days -----------> 9.5 pages
1 day ----------------> ?
= 0.95 page
approximately 1 page per day
Thus, Amy will need to read 1 page each day.

A square tile measures 20cm by 20cm. A rectangular tile is 3cm long and 2cm narrower than the square tile what is the difference in area between the two tiles
Answer:
346 cm²
Step-by-step explanation:
Area of square:
Area = [tex]Length*Length[/tex]
A = 20*20
A = 400 cm²
Area of rectangle:
Length = 3 cm
Width = 20-2 = 18 cm
Now, The Area:
Area = [tex]Length * Width[/tex]
Area = 3 * 18
Area = 54 cm²
Now, The difference in their areas:
=> 400-54
=> 346 cm²

Which is the ordered pair for the point on the x-axis that is on the line parallel to the given line and through the given point (-6,10)
Answer:
Option (1). (6, 0)
Step-by-step explanation:
The given question is incomplete; here is the complete question.
Which is the ordered pair for the point on the x-axis that is on the line parallel to the given line and through the given point (–6, 10)?
(6, 0)
(0, 6)
(−5, 0)
(0, −5)
Line in orange color is passing through two points (-8, 6) and (4, -4)
Slope of this line = [tex]\frac{\triangle y}{\triangle x}[/tex]
= [tex]\frac{6+4}{-8-4}[/tex]
= [tex]-\frac{10}{12}[/tex]
= [tex]-\frac{5}{6}[/tex]
Other line parallel to this line will have the same slope 'm' = [tex]-\frac{5}{6}[/tex]
Parallel line passes through a point (-6, 10).
Let the other point through which the parallel line passes is (a, b)
Now, [tex]-\frac{5}{6}[/tex] = [tex]\frac{10-b}{-6-a}[/tex]
-5(-a - 6) = 6(10 - b)
5a + 30 = 60 - 6b
5a = -6b + 60 - 30
5a = -6b + 30
a = [tex]-\frac{6}{5}b+6[/tex]
By satisfying with all the options we find only (6, 0) satisfy this equation.
6 = [tex]-\frac{6}{5}(0)+6[/tex]
6 = 6
Therefore, (6, 0) is the other point lying on the parallel line.
Option (1) will be the answer.

In triangle ABC points M and N lie on sides AB and BC, respectively such that MN∥ AC . Segments AN and CM intersect at point K and AK = KC. Prove that △ABC is isosceles.
Answer:
Step-by-step explanation:
An isosceles triangle has two equal sides and two equal base angles.
Given that : AK = KC and MN∥ AC
ΔMNB is similar to ΔACB (congruence property)
ΔANB = ΔANC (SAS congruence property)
ΔCMB = ΔCMA (SAS congruence property)
[tex]\frac{AB}{BN}[/tex] = [tex]\frac{AC}{CN}[/tex] (Angle bisector theorem)
So that:
<BAC = <ACB (base angle property of an isosceles triangle)
/AB/ = /BC/ (side property of an isosceles triangle)
Therefore, ΔABC is an isosceles triangle.

Find the surface area of the cylinder. Round to the nearest hundredth.
Answer:
The surface area of the cylinder is 276.32m²
Step-by-step explanation:
To solve this problem we have to calculate the circle area and the lateral area
To calculate the area of the circle we use the following formula
a = area
r = radius = 2m
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (2m)²
a = 3.14 * 4m²
a = 12.56m²
The area of the circle is 12.56m²
To calculate the lateral area of the cylinder we use the following formula
a = area =
h = heighti = 20m
r = radius = 2m
π = 3.14
a = 2 * π * r * h
we replace with the known values
a = 2 * 3.14 * 2m * 20m
a = 6.28 * 40m²
a = 251.2m²
The lateral area of the cylinder is 251.2m²
Now we add the lateral area of the cylinder with 2 times the area of the circle and obtain the area of the cylinder
251.2m² + (2 * 12.56m²) = 276.32m²
The surface area of the cylinder is 276.32m²
