Answer: 8.4
Answer:
(1) Please find attached the graph of the data
(2) 160.396 m
(3) The correlation that exist is a straight line correlation
Step-by-step explanation:
The given data are;
Distance, Time
(m), (s)
50, 6.1
100, 12
150, 18.3
200, 25.2
250, 31.7
(2)
Based on the linear regression formula, we have;
The line is
y = 7.7581×x+5.234
When t = 20 s, we have
y = 7.7581*20+5.234 = 160.396 m
(3) The correlation that exist is a straight line correlation
The function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
<h3>Exponential equation</h3>
The inverse of exponential equation is logarithmic equation. The standard exponential equation is expressed as;
y = ab^x
where
a is the initial value
b determine the growth rate or decay.
If the value if b < 1, then it is a decay otherwise it is growth.
Given the function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.

Answer:
are u a girl
Step-by-step explanation:
Answer:
E
Step-by-step explanation:
The parent function y = | x | has it's vertex at the origin
Here the vertex is at (- 4, 2)
That is shifted 4 units to the eft of the origin, thus
y = | x + 4 |
Shifted 2 units up is denoted by + 2, thus
y = | x + 4 | + 2 → E
