A. Answer: y = 32.913(1.126)ˣ
<u>Step-by-step explanation:</u>
You are given two coordinates (2, 53) and (9, 122). Use these to create a system of equations:
53 = a(b)² and 122 = a(b)⁹
122 = a(b)²· (b)⁷
122 = 53 · (b)⁷
1.126 = b
Substitute the b-value into either of the equations to solve for "a":
53 = a(1.126)²
32.913 = a
Input the a- & b-values into the general form of an exponential equation:
y = a(b)ˣ
y = 32.913(1.126)ˣ

B. Answer: 23 minutes
<u>Step-by-step explanation:</u>
Substitute y = 500 into the equation above to solve for x:
500 = 32.913(1.126)ˣ
So the hypothenuse will have a length of x - so using pythagora's theorem you can calculi it easy
x^2 = 25 +16
x = sqrt41
20 minutes !!!! Hope this helps
Answer:
The answer to your question is below
Step-by-step explanation:
To solve this problem, for a and c, just look in the x-axis the value given and find the value of a and c in the y-axis.
To solve this problem, for b and d, just look in the y-axis the value given and find the value of b and d in the x-axis.
f(2) = -3 a = -3
f(b) = 0 b = -4
f(-2) = -1 c = -1
f(d) = -6 d = 8
Answer: 9.24
Step-by-step explanation:
4.9+ -1.2(0.7)- - 5.18
+ + = +
+ - = - + = -
- - = +
Therefore:
4.9+ -1.2(0.7)- - 5.18 = 4.9 - 1.2*(0.7) + 5.18 =4.9 - 0.84 + 5.18 = 9.24
