Hi There!
The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of years since the tournament first started.
T(x)=4x+24
The entire fee paid by each team to enter the tournament can be modelfied by function F, where x is the number of years since the tournament first started.
F(x)=5x+45
Which function,R, best represented the total entry fees collected in the xth year since the tournament first started?
Answer - D. R(x)=9x+69
Option D makes the most sense for the following question because since whatever x is multipled by the number thats just added so you just combine like terms and do 24 + 45 = 69.
Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x²
For x = a,
f(a) = 8a²
Now substitute these values in the expression,
=
=
=
= 8(x + a)
b). =
=
=
= (8h + 16x)
= 8(h + 2x)
Answer:
78.5 un²
Step-by-step explanation:
A = π · r²
π · 10²
314 un²
314 un² ÷ 4
78.5 un²
Answer:
I agree with Claire's representation. Sea level is considered as zero, going up in the number line is positive and going down in the number line is negative.
The location 10 feet above sea level is correct. We have to count 10 spaces going upwards from zero. This location is represented by the integer 10.
The location 10 feet below sea level is correct. We have to count 10 spaces going downwards from zero. This location is represented by the integer -10.
Step-by-step explanation:
The attached picture shows two points:
The red point represents 10 feet above sea level. (Integer: 10)
The blue point represents 10 feet below sea level. (Integer: -10)
Sea level is zero.
