Answer:
1 : 2401
Step-by-step explanation:
Given that:
Area of solid = 1cm²
New area after dilation = 2401 cm²
The scale factor :
Old area : new area
1 cm² / 2401 cm²
Hence, the scale factor is

A car is valued at $35400 at the start of the year, and at $25700 at the end of that year. During that year, the car travelled 25000kms.
a) Find the total depreciation of the car in that year in dollars
b) Find the depreciation per kilometre for this car
c) Using (initial value) -> V₀ = 35400, write down a rule for the value of the car Vₙ after ₙ kilometres
d) How many kilometres are travelled when the value of the car is $6688?
e) Including the first year of travel, how many kilometres in total is this car expected to drive before it has a value of 0?
a. Total depreciation = $9700
b. Depreciation per kilometer = $0. 388 per kilometer
c. Vₙ = $35400 + ₙt
d. Distance = 4723. 16 kilometers
e. Total distance = 29723. 16 kilometers.
How to determine the depreciation
i. The formula for total depreciation is given as;
Total depreciation = Cost of asset - Residual value
Cost of car = $ 35400
Residual value = $25700
Total depreciation = $35400 - $25700
Total depreciation = $9700
b. Depreciation per kilometer = Total depreciation/ distance travelled in kilometers
Depreciation per kilometer = $ [tex]\frac{9700}{25000}[/tex]
Depreciation per kilometer = $0. 388 per kilometer
c. Vₙ = V₀ + ₙt
t = time of depreciation
V₀ = $35400
Vₙ = $35400 + ₙt
d. When the car costs $35400, it travelled 25000 kilometers
It costs $6688, it would travel 'x' kilometers
Cross multiply
$35400 × x = $ 6688 × 25000 kilometers
Make 'x' subject
x = [tex]\frac{6688 * 25000}{35400}[/tex]
x = [tex]\frac{167200000}{35400}[/tex]
x = [tex]4723. 16[/tex] kilometers
The car would travel 4723. 16 kilometers
e. To find the total distance
Total distance = 25000 + 4723. 16
Total distance = 29723. 16 kilometers.

If a wall is built in a room at a 36 degree angle. The angle formed in the other room by the wall is 144 degrees. What kind of angles are formed when they are added together
They form supplementary angles when they are added together.
Reason for Being Called Supplementary Angles
It is given that the angle made by the wall in one room is 36° and the angle formed by the same wall in the other room is 144°.
This implies that,
∠1 = 36°
∠2 = 144°
∠1 and ∠2 are adjacent angles and,
∠1 + ∠2 = 36° + 144°
⇒ ∠1 + ∠2 = 180°
Hence, these two adjacent angles make a straight-line angle. Hence, they are supplementary angles.
What are supplementary angles?
Two angles that form a straight line angle, that is, angle equal to 180°, when they are added together are said to be a pair of supplementary angles.

The distance between the skate and point X is 16 feet
Given that the distance between point X and kite is 12 feet
and the distance between stake and kite is 20 feet
We need to find the distance between the stake and point X
Here,
Perpendicular = 12 feet
Hypotenuse = 20 feet
Base = ?
According to Pythagoras Theorem
(Hypotenuse)² = (Perpendicular)²+(Base)²
(20)² = (12)² + (Base)²

The area of the sector in radians is calculated as: B. 8π units squared.
What is the Area of a Shaded Sector?The area of a sector where the central angle of the sector that is shaded in a circle is given in radians is calculated using the formula that is expressed as:
Area of sector = (1/2) × r²θ; where we have:
θ = the angle subtended at the center/central angle measure in radians
r = the radius of the circle
Given the following:
The shaded area is half of the circle. Its measure would be 180 degrees which when expressed in radians would be π.
Central angle measure in radians (θ) = π
Radius (r) = 4 units
Plug in the values into the area of sector formula
Area of sector = (1/2) × r²θ = (1/2) × (4²)(π)
Area of sector = (1/2) × (16)(π)
Area of sector = (1 × 16 × π)(2)
Area of sector = (16π)(2)

How to find the equation of the line for the height of a triangle
In this question we must find the equation of the line perpendicular to the segment BC and that goes through the point A(x, y) = (1, 3). First, the slope of the line segment BC is:
m = [1 - (- 3)]/[5 - (- 3)]
m = 4/8
m = 1/2
And the slope of the line is:
m' = - 1/(1/2) = - 2

Answer:

Step-by-step explanation:
We will use the order of operations to evaluate the expression.
From left to right , Multiplication/Division followed by Addition/Subtraction.
21 / 3 + 8 - 4
= 7 + 8 - 4
= 15 - 4
= 11
Therefore, the answer is D
Answer:
D) 11
Step-by-step explanation:
Division and multiplication always comes first in an equation. Since there is no multiplication in the expression, we can divde first.
21 / 3 = 7
Our new expression will be: 7 + 8 - 4
Now we can just add (7) , (8), and (-4) not caring about the order, since they are all addition or subtraction.
I'll do the addition first, but order does not matter.
7 + 8 = 15
15 - 4 = 11
So 11 is our final answer.

Now that we know g(-2) is -4, we can apply this to f:
