[tex]\left(x^{2}-6\right)(x+5)[/tex] are the factors of the expression by grouping
Step-by-step explanation:
[tex]x^{3}+5 x^{2}-6 x-30[/tex]
We have to group the terms as,
[tex]\left(x^{3}+5 x^{2}\right)-(6 x-30)[/tex]
We can take the common factors as,
= [tex]x^{2}(x+5)-6(x+5)[/tex]
So it can be written as,
= [tex]\left(x^{2}-6\right)(x+5)[/tex]

Gardner want to fence a circular garden of diameter 21 metre find the length of the wire he needs to purchase and cost of it at rupees 4 per metre
The cost of wire to purchase is Rs 264.
Step-by-step explanation:
Given,
The diameter of the circular garden is 21 m
The radius(r) = [tex]\frac{21}{2}[/tex] m
To find, the length of wire of the fence we need to find the circumference.
Formula
The circumference of the circle = 2πr meter
=2×[tex]\frac{22}{7}[/tex] ×[tex]\frac{21}{2}[/tex] m
=66 meter
So, the length of the wire = 66 m
The cost of wire Rs 4 per meter.
The total cost = Rs 4 × 66
= Rs 264
the filing cabinets need a total of 55 square feet of space.the doctor asked in which room the filing cabinets will fit
Square B
Explanation:The complete question is written in a comment above. The doctor's office where you work needs to store eight filing cabinets with patient information in one of three secure storage rooms. We know that the filing cabinets need a total of 55 square feet of space. You need to identify in which room the filing cabinets will fit. So we have three rooms:
FIRST OFFICE:
[tex]Square \ A = 8 \times 5[/tex]
In other words, for this room we have the following area:
[tex]Square \ A =40ft^2[/tex]
SECOND OFFICE:
[tex]Square \ B = 9 \times 7.5[/tex]
In other words, for this room we have the following area:
[tex]Square \ B =67.5ft^2[/tex]
THIRD OFFICE:
[tex]Square \ C = 5 \times 10[/tex]
In other words, for this room we have the following area:
[tex]Square \ C =50ft^2[/tex]
How can we know what is the room we need to choose?
Well, the room we need to choose is the one whose area is greater than the area of the filling cabinets. In other words, let's call square x the unknown room, then:
[tex]Square \ x>55ft^2[/tex]
From the, choices the only room that meets our requirements is square B because:
[tex]Square \ B>55ft^2 \\ \\ 67.5ft^2>55ft^2[/tex]
Measure the length and width of a room in feet to calculate its area. Multiply these dimensions to get the area in square feet. The filing cabinets need a room with at least 55 square feet.
Explanation:To determine whether the filing cabinets will fit into a room, we must calculate the area of the room and see if it is at least 55 square feet, the space required for the filing cabinets.
To calculate the area of a room in square feet, measure the length and width of the room in feet and then multiply these numbers together.
For example, if a room is 10 feet wide and 5.5 feet long, its area would be 10 feet times 5.5 feet, which equals 55 square feet. Therefore, the filing cabinets would fit in a room of this size.

10. An archery arrow is shot with a speed of 45 m/s at an angle of 10°. How for
horizontally can the arrow travel before hitting a target at the same height
from which it was released?
Answer:
The horizontal distance travelled by an arrow is 70.6 m.
Step-by-step explanation:
Given : An archery arrow is shot with a speed of 45 m/s at an angle of 10°.
To find : How for horizontally can the arrow travel before hitting a target at the same height from which it was released?
Solution :
The expression for the range of the projectile motion is
[tex]R=\frac{V^2\sin 2\theta}{g}[/tex]
Where, the velocity of an arrow is V = 45 m / s
The angle of release of an arrow is [tex]\theta=10^\circ[/tex]
The acceleration due to gravity is g =9.81 m/s²
Substitute the values,
[tex]R=\frac{45^2\sin 2(10)}{9.81}[/tex]
[tex]R=\frac{2025\sin (20)}{9.81}[/tex]
[tex]R=70.6\ m[/tex]
Therefore, the horizontal distance travelled by an arrow is 70.6 m.
The arrow travels approximately 70.9 meters.
To determine how far the arrow travels horizontally, we need to break the initial velocity into horizontal and vertical components and use the projectile motion equations.
Step-by-step solution:
Determine the horizontal and vertical components of the initial velocity:The arrow travels approximately 70.9 meters horizontally before hitting a target at the same height from which it was released.
The atmosphere balances the unequal heating of Earth’s surface by moving _____. cool air toward the east and warm air toward the west cool air toward high latitudes and warm air toward the equator warm air toward the east and cool air toward the west warm air toward high latitudes and cool air toward the equator
Answer:
warm air toward high latitudes
Step-by-step explanation:
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. From google
The atmosphere balances the unequal heating of Earth’s surface by moving warm air toward high latitudes and cool air toward the equator.
What is Atmosphere?An atmosphere is a layer of gas or layers of gases that envelop a planet, and is held in place by the gravity of the planetary body.
The atmosphere balances the unequal heating of Earth’s surface by moving warm air toward high latitudes and cool air toward the equator.
This is because the Earth's surface is heated unequally due to differences in solar radiation and other factors.
The equator receives more direct sunlight and is therefore warmer, while the poles receive less direct sunlight and are cooler.
As a result, warm air rises at the equator and cool air sinks at the poles, creating a circulation pattern in the atmosphere known as the Hadley cell.
Hence, the atmosphere balances the unequal heating of Earth’s surface by moving warm air toward high latitudes and cool air toward the equator.

x = 7 and x = –7.
Solution:
Given data:
[tex]$f(x)=x^{2}+15[/tex] and [tex]f(x)=64[/tex]
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
[tex]x^2+15=64[/tex]
To isolate the constant term subtract 15 from both sides.
[tex]x^2+15-15=64-15[/tex]
[tex]x^2=49[/tex]
49 can be written as 7².
[tex]x^2=7^2[/tex]
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.

The length of SK = 10 units while the length of BK = 8.6602 units.
Step-by-step explanation:
Step 1:
In the given triangle, there are two right-angles triangles with 60° angles. The central line BK is the opposite side for both the triangles. For triangle RK the hypotenuse's length is 10 m. Assume BK = x units and SK = y units.
Step 2:
So first we calculate the length of BK (x).
As we have the values of the angle of the triangle and the hypotenuse, we can calculate the sine of the angle to determine the value of x.
[tex]sin R = \frac{oppositeside}{hypotenuse}, sin 60 = \frac{x}{10}.[/tex]
[tex]sin 60 = 0.86602, x = 0.86602 (10) = 8.6602 units.[/tex]
So x = BK = 8.6602 units.
Step 3:
So now we calculate the length of SK (y).
As we have the values of the angle of the triangle and the opposite side's length, we can calculate the sine of the angle to determine the value of y.
[tex]sin S = \frac{oppositeside}{hypotenuse}, sin 60 = \frac{86.602}{y}.[/tex]
[tex]sin 60 = 0.86602, y = \frac{8.6602}{0.86602} = 9.999units = 10 units[/tex]
So y = SK = 10 units.

45°
The Question is Incomplete, the Complete Question is with figure is below.
Answer:
Therefore,
The Measure of angle 6 is
[tex]\angle 6 =45\°[/tex]
Step-by-step explanation:
Given:
m∠1 = 135°
Lines b and c are parallel.
To Find:
m∠6 = ?
Solution:
Linear Pair:
A linear pair of angles is formed when two lines intersect.
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Example
∠ 1 and ∠ 2 ∠ 1 and ∠ 3 ,etc
[tex]\angle 1 + \angle 3 = 180\°[/tex]
Substituting the values we get
[tex]135 + \angle 3 = 180\\\\\angle 3 = 180-135=45\°[/tex]
Now,
Lines b and c are parallel. .Given
When Two lines are Parallel Alternate interior angles are equal
∠ 3 and ∠ 6 are Alternate Interior angles
[tex]\angle 3 = \angle 6[/tex]
But [tex]\angle 3 =45\°[/tex]
[tex]\angle 6 =45\°[/tex] ...Transitive Property
Therefore,
The Measure of angle 6 is
[tex]\angle 6 =45\°[/tex]

The solutions to the quadratic equation x^2 - 3x + 3 = 0 can be found using the Quadratic Formula. The solutions are complex numbers: x = 3/2 ± (i*sqrt(3))/2.
Explanation:The given equation is a quadratic equation of the form ax^2 + bx + c = 0. To find the solutions to this equation, we can use the Quadratic Formula: x = [-b ± sqrt(b^2 - 4ac)] / (2a).
Here a=1, b=-3, c=3.
Plugging these values into the formula,
we get x = [3 ± sqrt((-3)^2 - 4*1*3)] / (2*1).
Simplifying this equation will give us x = [3 ± sqrt((9 - 12)] / 2.
Now, note that the value under the square root is negative, indicating that the solutions will be complex.
Finally, we have the solutions:
x = [3 ± sqrt(-3)] / 2
= 3/2 ± (i*sqrt(3))/2, where 'i' is the imaginary unit.

The radius of a fishing line is 2.5*10^-4 foot. Write this number in standard form. Then write your answer using inches.
To write the radius of the fishing line in standard form, it is 0.00025 foot. In inches, the length is 0.003 inches.
Explanation:The radius of the fishing line is given as 2.5*10^-4 foot. To write this number in standard form, we first need to convert it into decimal form.
To do this, we move the decimal point four places to the left, since the exponent is negative. This gives us 0.00025.
Therefore, the number in standard form is 0.00025 foot.
To convert this into inches, we know that there are 12 inches in a foot. So, we multiply the length in feet by 12 to get the length in inches.
Therefore, the length of the fishing line in inches is 0.00025 foot * 12 inches/foot = 0.003 inches.
