The value of B using Pythagoras theorem is 20 cm.
Pythagoras theorem?Pythagoras' theorem states that the square of the hypotenuse in a right- angle triangle is equal to the sum of the square of the two other sides.
Formula:
A² = B²+C²........... Equation 1Make B the subject of the equation
B² = A²-C²B = √(A²-C²)................ Equation 2From the question,
Given:
A = 25 cmC = 15 cmSubstitute these values into equation 2
B = √(25²-15²)B = √(625-225)B = √(400)B = 20 cm.Hence, The value of B using Pythagoras theorem is 20 cm.

A.
6x + 9
B.
8x + 12
C.
12x + 18
D.
16x + 24
Answer:16X + 24 D

Answer:
x=2, y=-4
Step-by-step explanation:
If you put a vertical or horizontal line straight through the shape and it looks the same, then it is symmetrical. You can put a symmetrical line both vertically AND horizontally. To do this, you just need a line going through the points at the tips and the points at the sides of the quadrilateral. A line that is vertical will be an x=, because it only covers one x-value. So, the line for x will be x=2, because it goes through both tips of the quadrilateral. A horizontal line will be y= because it only covers one y-value. So, the line for the horizontal line will by y=-4, because this goes through both sides of the quadrilateral.

A quadratic function is represented as a (x - h)² + k, when a is negative then, the vertex of the function is a maximum. In both functions, the value of a is -1. This means that both functions are at a maximum
The values of k in both functions are k = 1 and k = 5. By comparison, 5 is greater than 1. Therefore, function 2 has larger maximum.

how do you find the perfect square (x+1)^2=0
Answer:
By multiplying the term by itself (x+1)(x+1)
Some people like to use the box technique, which formats like this:
x + 1
x x^2 1x
+
1 1x 1
The terms multiply in columns, and then add all together
So
x^2 + 1x + 1x + 1 can be simplified to x^2+2x+1 = 0, which is the perfect square of (x+1)^2 = 0

A chef has two dozen meatballs to add to a pot of sauce. Each meatball has a two-inch diameter. Before the meatballs are added, the sauce is 2 inches from the top of the 14-inch diameter pot. Will the sauce spill over when the chef adds the meatballs to the pot? Show all of your work to justify your answer.
Given the volume of the space in the pot and the volume of the meatballs, the sauce will not spill over.
Will the sauce spill over?
The first step is to determine the volume of the remaining space that the sauce is yet to fill. A pot usually has the shape of a cylinder, so the formula for the volume of a cylinder would be used.
Volume of a cylinder = πr²h
π x (14/2)³ x 2 = 98 in³
The second step is to determine the volume of the two dozen meatballs.
Volume of a sphere = 4/3πr³
24 x (4/3 x π x (2/2)³) = 32π in³
To learn more about the volume of a sphere, please check: https://brainly.com/question/13705125
#SPJ1
The sauce will spill over if the volume of the pot is less than 146π in³ and it will not spill over if the volume of the pot is more than 146π in³.
Volume of the sauce in the potThe volume of sauce in the pot is calculated as follows;
V = πr²h
V = π x (7)² x (2)
V = 98π in³
Volume of the two dozen meatballsArea of 1 meatball = πr² = π x (1)² = π in²
Area of the 2 dozen = (2 x 12) x A
= 24 x π in² = 24π in²
the height of each meatball = 2 in,
Volume of the 2 dozens = 2 in x 24π in² = 48π in³
Total volume of the meatball and sauce in the pot = 98π + 48π = 146π in³
Thus, the sauce will spill over if the volume of the pot is less than 146π in³ and it will not spill over if the volume of the pot is more than 146π in³.

Find the zeroes of the function and state their multiplicities.
q(x) = 10x^3 - 58x^2 + 40x
In rhombus ABCD, AB=12 and AC=22. Find the area of the rhombus to the nearest 10.
a) 195
b) 221.3
c) 105.5
d) 100.8
Answer:
c) 105.5 square units
Step-by-step explanation:
The area of a rhombus can be computed as half the product of the diagonal lengths.
__
Half the diagonal BD will be one leg of the right triangle formed by the diagonals and the sides of the rhombus. The length of that leg is found using the Pythagorean theorem:
a² +b² = c²
11² +b² = 12²
b² = 144 -121 = 23
b = √23 ≈ 4.796
This value is half the length of diagonal BD, so multiplying it by the length of diagonal AC will give the area of the rhombus.
Area = 1/2(AC)(BD) = (22)(4.796) ≈ 105.5 . . . . square units

What is the approximate length of arc s on the circle below? use 3.14 for pi. round your answer to the nearest tenth. a circle is shown. 2 rays form an angle of 45 degrees. the length of the rays is 8 inches. arc s contains the angle measuring 45 degrees. 5.6 in. 6.3 in. 14.3 in. 25.1 in.
The length of an arc with central angle of 45 degrees and radius of 8 inches is 6.3 inches.
How to find length of an arc?length of an arc = ∅ / 360 × 2πr
where
∅ = central angler = radiusHence,
r = 8 inches
∅ = 45 degrees
Therefore,
length of an arc = 45 / 360 × 2 × 3.14 × 8
