Answer:
Q6. 49π or about 153.94
Q7. 42
Q8. 17.5
Step-by-step explanation:
6. the formula for the area of a circle is πr², and you have that r, or the radius, is 7. then, you just plug that in, which would be π·7² = π·49 = 49π.
7. the formula for the area of a parallelogram is base times height, and you have base = 6 cm and height = 7 cm. this means the area is 6 · 7 = 42.
8. The formula for the area of a triangle is base times height divided by 2, and you have base = 5 and height = 7. this means the area is 5 · 7 ÷ 2 = 35÷2 = 17.5
A relation is the relationship between variables. When each input has one output, the relation is a function. When the value of k is 5 or 3, the relation will not be a function.
Given that:
For S, not to be a function, 1 domain element must point to more than one range elements.
This means that:
Collect like terms
Multiply by -1
Remove absolute bracket
Solve for k
Hence, when k is 5 or 3, the relation will not be a function.
