The answer to the problem is B.
Answer:
t is between 0 seconds and 4.878
Step-by-step explanation:
Given:
Inequality:
Required
Determine the value(s) of t
To answer this question, we simply solve the inequality
Subtract 10 from both sides
Multiply through by -1
Solve the value of t using quadratic formula
Where
<em>a = 4.9; b = -22 and c = -9.25</em>
So:
Split the expression
or
or
or
Since t cannot be negative; Then
<em>Hence; t is between 0 seconds and 4.878</em>
Answer:
x = 1
y = -1
Point = (1,-1)
Step-by-step explanation:
2x + 3y = -1 = y = -2/3 - 1/3
5x + 2(-2/3 - 1/3) = 3
5x - 1 1/3 - 2/3 = 3
5x - 2 = 3
<u> +2 +2</u>
5x = 5
<em><u>x = 1</u></em>
2(1) + 3y = -1
2 + 3y = -1
<u>-2 -2</u>
3y = -3
<em><u>y = -1</u></em>
Answer:
Sean's office is 8ft bigger than Beth's office.
Step-by-step explanation:
If you multiply 8 by 5 you get 40 which is how big Sean's office is.
If you multiply 4 by 8 you get 32 which is how big Bth's office is.
Then you subtract 40-36 you get 8 which is the difference between Sean and Beth's offices.
Hope that helped! :)
Answer:
Step-by-step explanation:
By looking at your graph, The y intercept is (0,4).
This is an exponential function so it is represented by
where a is the vertical stretched and b is the constant rate and x is the nth power.
let plug in 0,4
since anything to the 0 power is 1.
Know let plug it in to this equation.
Let use 2,1 another point on the graph
Divide 4 by both sides
take sqr root of 0.25
So
the answer is
