Answer:
P(t) = 282.2(1.009)^t
Step-by-step explanation:
Look at the attached image.
Hope you can read my handwriting. the image cut off the right side, b = 1.009213324... but question asks to round to nearest thousandth so it's 1.009
For the second part just use the equation to find P when t = -1 and see if P is less than (underpredicts) the number from the question or greater than (overpredicts) the number. I haven't calculated it but I think it will be smaller and thus underpredicts just from looking at the numbers when t = -1
Answer:
x = -2
Step-by-step explanation:
7x -6y = -20
y=1
7x - 6 = -20
7x = -14
x = -2
Answer:
Tried my best..... Hope it helps! :)
∠1 and ∠2 are supplementary angles, and so they will equal 180°
note that:
m∠1=4x+3
m∠2=3x−5
Plug in the corresponding expression for the angle
(4x + 3) + (3x - 5) = 180
Simplify. Combine like terms
7x - 2 = 180
Isolate the x. Note the equal sign. What you do to one side you do to the other.
Add 2 to both sides
7x - 2 (+2) = 180 (+2)
7x = 182
Divide 7 from both sides
7x/7 = 182/7
x = 182/7
x = 26
26 is your answer for x.
hope this helps
