Answer:
5.2 in
Step-by-step explanation:
An equilateral triangle is a triangle with 3 equal sides
Divide the equilateral triangle into two congruent triangles and use Pythagoras theorem to find the height
The Pythagoras theorem : a² + b² = c²
where a = height
b = base = 6 in / 2 = 3 in
c = hypotenuse = 6 in
6² = 3² + h²
h = 36 - 9 = 27
√27 = 5.196 inch
to the nearest tenth = 5.2 in
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
If the radius of the circle below is 12 feet, find the area of the shaded region.
Answer:
The area of the shaded region is 195.84sqft.
Step-by-step explanation:
Area of shaded region = area of trapezium- area of circleArea of shaded region= 1/2(sum of parallel side)*height - π[tex](radius)^{2}[/tex]
Area of shaded region=1/2(20+34)*24 - π[tex](12)^{2}[/tex]

Step-by-step explanation:
answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4
step-by-step explanation:
polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!
complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.
the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7
verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.
a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

Complete the equation so it will have no solution. 5x - 8 = _ +2
Answer:
5x
Step-by-step explanation:
If the blank were to be occupied with 5x there would be no solutions
Observe...
5x - 8 = 5x + 2
* subtract 5x from each side *
5x - 5x cancels out
5x - 5x cancels out
we're left with -8 = 2
which is not true
Hence if the blank = 5x the equation will have no solution

Find the perimeter of the right triangle. If necessary, round to the nearest tenth. a. 13 in. b. 169 in. c. 60 in. d. 30 in.
Question: Find the perimeter of the right triangle. If necessary, round to the nearest tenth. 4 cm 15 cm a. 15.5 cm
b. 30 cm
c. 60 cm
d. 34.5 cm
Answer:
d. 34.5 cm
Step-by-step explanation:
Applying
Perimeter of the right triangle (P) = a+b+c
P = a+b+c.................... Equation 1
But we can find the hyotenuse (a) using pythagoras theorem
a² = b²+c²
a = √(b²+c²)............... Equation 2
Substituting equation 2 into equation 1
P = √(b²+c²)+b+c................... Equation 3
From the diagram,
Given: b = 4 cm, c = 15 cm
Substitute these values into equation 2
P = √(4²+15²)+4+15
P = √(241)+4+15
P = 15.5+4+15
P = 34.5 cm
Hence the right answer is d. 34.5 cm

Which shows how to determine the volume of the pyramid?
Answer:
d would be correct
Step-by-step explanation:
A pyramid is a polyhedron formed by connecting a polygonal base and an a a p e x. The basic formula for pyramid volume is the same as for a cone: volume = (1/3) times base area times height, where height is the height from the base to the a p e x. That formula is working for any type of base polygon and oblique and right pyramids.

Equilateral triangles are
acute triangles.
Scalene triangles are
acute triangles.
Right triangles are
acute triangles.
Obtuse triangles are
isosceles triangles.
Answer:
Equilateral triangles are always acute triangles.
Scalene triangles are sometimes acute triangles.
Right triangles are never acute triangles.
Obtuse triangles are sometimes isosceles triangles.
Step-by-step explanation:
Equilateral triangles are always acute because each angle is 60⁰.
Scalene triangles have sides that are different lengths. They can be right, obtuse, or acute.
A right triangle is never acute because it has a 90⁰ angle. Acute means all angles are less than 90⁰.
An obtuse triangle can be either scalene or isosceles. It always has one angle greater than 90⁰ (obtuse).
