A translation is a transformation in which the figure is simply moved across space; the preimage is congruent to the image.
We are told that the y-coordinate of the preimage increase by 8. We know that the y-coordinates have to do with vertical movement on a coordinate plane. Since the y-coordinates increased by 8, the preimage was moved up 8 units.
The correct option is A.

Answer:
About 428 N
Step-by-step explanation:
Weight = 1,500 * 9.8 = 14,700 N
Density = Mass ÷ Volume
1,030 = 1,500 ÷ V
V = 1,500 ÷ 1,030 = 1.46 m^3.
Buoyant force = Density * g * V
Buoyant force = 1,000 * 9.8 * (1,500 ÷ 1,030)
Buoyant force = 9,800 * (1,500 ÷ 1,030) = 14,272 N.
Net force = 14,700 – [(9,800 * (1,500 ÷ 1,030)]
Final answer:
The upward normal force on a 1500 kg submerged hippo is approximately equal to its weight, calculated as its mass times the acceleration due to gravity (1500 kg × 9.81 m/s²), resulting in a force of 14715 N.
Explanation:
The question is asking about the upward normal force on a submerged hippo in a lake. To find this force, we must understand that the upward normal force that the ground (or in this case, the lake bed) exerts on the hippo is equal to the weight of the hippo, which is the product of the hippo's mass (m) and the acceleration due to gravity (g).
In equation form: Normal Force = m × g. Plugging in the values, we have a 1500 kg hippo and the acceleration due to gravity is approximately 9.81 m/s². Therefore, the upward normal force is:
Normal Force = 1500 kg × 9.81 m/s² = 14715 N.
This is the approximate value of the upward normal force exerted on the hippo standing on the bottom of the lake.

1 jar of mayo costing £1.80
2 loaves of bread
she pays with a £10 note and gets £1.60 change. Barbra works out that the cost of 1 loaf of bread is £1.40 .
Is she correct? You MUST show your working out
Answers
Answer:
No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Barbara buys 3 boxes of eggs costing £1.20 each
1 jar of mayo costing £1.80
2 loaves of bread
she pays £10 note and gets £1.60 change
Barbara works out the cost of 1 loaf of bread as £1.40.
Is she correct? You MUST show your working out.
The explanation of the answer is now given as follows:
Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60
Cost of 1 jar of mayo = £1.80
Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40
Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00
Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50
Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.
