Answer:
3 In²
Step-by-step explanation:
Talking about surface area, the total area of an object is taken into consideration.
NB: Kindly check the attached picture for the diagram of the 3D object.
In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.
Surface Area = 6 × k².
Surface area = 6 × ( 1.8 × 1.8) cm².
Surface Area = 19.44 cm².
The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------> x in².
19.44 × 0.155 in² = 3 in².
Answer:
C. The domain is (-1,+∞), and the range is all real numbers.
Step-by-step explanation:
The domain is (-1,+∞) because the expression ln(x+1) exists only if x>-1
and the range is all real numbers.

Answer:
(a)4 units, 3 units
(b) Right-angled triangle
Step-by-step explanation:
We are given that
Let location of drinking fountain, A =(-4,2)
Location of the bench, B=(0,2)
Location of the center of the slide ,C=(0,5)
a. Distance formula
Using the formula
units
Hence, the distance from the drinking fountain to the bench=4 units
The distance from the bench to the center of the slide=3 units
(b)
units
The triangle ABC satisfied the Pythagoras theorem. Hence, the triangle ABC is a right angled triangle.
