Type the correct answer in each box. use numerals instead of words. consider the quadratic equation x2 10x 27 = 0. completing the square leads to the equivalent equation (x )2 = .
The equivalent equation using the completing the square method is (x+5)² = -2
Completing the square method.Quadratic equations are equation that has a degree of 2. Given the equations expressed as:
x^2+10x+27 = 0
Subtract 27 from both sides
x^2+10x = -27
Complete the squares
x^2+10x = -27

Rewrite and expand the given limand as the product
[tex]\displaystyle \lim_{t\to0}\frac{\sin(6t)}{\sin(2t)\cos(6t)} = \lim_{t\to0} \frac{\sin(6t)}{6t} \times \frac{2t}{\sin(2t)} \times \frac{6t}{2t\cos(6t)} \\\\ = \left(\lim_{t\to0} \frac{\sin(6t)}{6t}\right) \times \left(\lim_{t\to0}\frac{2t}{\sin(2t)}\right) \times \left(\lim_{t\to0}\frac{3}{\cos(6t)}\right)[/tex]

Does Anybody know this? Find the area of the shaded sector
Step-by-step explanation:
your teacher was very nice and warned you about the trap in the question.
so, really, what do we have to do ?
a full circle represents 360°.
the shaded sector is the full circle minus the white sector !
this is the same as directly calculating the shaded sector for 360-75 = 285°.
so, the area of a circle is
pi×r²
in our case
pi×20² = 400pi
the needed fraction of the whole circle is either
75/360, if we want to subtract it for the solution
or
285/360, if we want to calculate the solution directly.
both lead to the same result.
400pi×360/360 - 400pi×75/360 =
= 400pi × 285/360 = 10pi × 285/9 = 2850pi/9 =
= 316.6666666...pi ≈ 316.7pi

What is a square?It is a polygon with four sides. The total interior angle is 360 degrees. A square's opposite sides are parallel and all sides are equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
There are two squares.
The perimeter of square x is half the perimeter of square y.
Let the side of the square x be a and the side length of the square y be b. Then we have
Perimeter x = Perimeter y / 2
4a = 2b
2a = b
Then the area of the square x will be
Area of square x = (2a)²
Area of square x = 4a²
Then the area of the square y will be
Area of square x = (b)²
Area of square x = b²
Then the area of square x will be one-fourth of the area of square y.
Thus, the correct option is C.

The volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.
What is a sphere?It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.
We know the surface area of the sphere is given by:
SA = 4πr²
1465 = 4πr²
r = 10.79 cm
Volume of the sphere = 4πr³/3
V = 4π(10.79)³/3
V = 5262.03 cubic cm
Volume of five volleyballs = 5×5262.03 = 26310.15 cubic cm
Thus, the volume of five volleyballs is 26310.15 cubic cm if the volleyball has a surface area of 1465 square cm.

how do you measure the perimeter of a shape
Perimeter is a measure of the area or distance around a two-dimensional shape. On a rectangle, for instance, the perimeter is the total length of the rectangle's outline, including the two widthwise borders and the two lengthwise borders.
To determine the perimeter of a shape, therefore, you add together all the dimensions that make up the shape's outer edge. Being able to find the perimeter of a shape has many applications in the real world. Say, for example, that you wanted to build a fence around your backyard. In order to purchase materials, you need to know how much fencing you'll need, and to determine that you have to figure out the perimeter of the area you want to fence in.

130
Step-by-step explanation:
We have given in the question 'she put 10 apples into each of 4 baskets.
Into = Multiplywe have to Multiply 10 with 4
=> 10 × 4
=> 40 Apples
Similarly, in the case of oranges we have to Multiply 10 with 3
=> 10 × 3
=> 30 Oranges
Same method will be followed to find the number of peaches that she picked .
=> 12 × 5
=> 60 Peaches
Total fruits Amber picked = Number of apples + Number of oranges + Number of peaches
=> Total fruits = 40 + 30 + 60
=> Total Fruits = 130 .
