Answer:
Step-by-step explanation:
There's a graph only for (-5, 5), which is the domain of this function.
Answer:
The amount the car will be worth after 6 years is £21,917 and 22 pence
Step-by-step explanation:
The amount for which Colin buys the car, PV = £28,100
The amount by which the car depreciates each year, r = 4%
The number of years after which the value of the car is sought, n = 6 years
The future value, FV, based on an annual depreciation is given as follows;
Substituting the known values gives;
Therefore, the amount the car will be worth after 6 years, future value FV₆ = £21,917 and 22 pence
1) No, you cannot add term together if they are not like terms, this would only work if they were being multiplied.
2) Triangles that are congruent have the exact same size and shape, all angles and side lengths are equal to each other.
Triangles that are similar have the same shape but maybe not the same size. They have side lengths that have equal ratios to each other but don't need to be the same length.
EX: Congruent: sides are 3 4 and 5 for both triangles.
Similar: Sides are 3 4 and 5 for one triangle and 3 8 and 10 for the other
Answer:
The numbers are 87, 88, 89 and 90.
Step-by-step explanation:
Let the numbers be x, x+1, x+2 and x+3.
x + x +1 + x + 2 + x + 3 = 354
4x + 6 = 354
4x = 348
x = 348 / 4
= 87.
Answer:
Perimeter of the final star = 40 cm²
Step-by-step Explanation:
The perimeter of the six-pointed star is the sum of the sides of the 6 equilateral triangles that form a boundary around the star.
1 triangular tiles gas a perimeter of 10cm.
Only 2 out of the 3 equal sides of each of the 6 equilateral triangles form the boundary of the final star.
Therefore, perimeter of the final star = ⅔ of the total perimeter of 6 triangular tiles
= ⅔ of (10*6)
= ⅔*60
= 2*20
Perimeter of the final star = 40 cm²
