1a. y = 2(11/5)^-x
2b. y= e^-2x
3c. y= 1/4e^x
9514 1404 393
Answer:
decaydecaygrowthStep-by-step explanation:
If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.
Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.
__
1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay
2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay
3. y = 1/4e^x . . . . e > 1, so growth

e ≈ 2.71828 . . . an irrational number

Fill in the blank. In the triangle below, x =
decimal places.
Round your answer to two
Answer:
x = 44.80
Step-by-step explanation:
Apply trigonometric function to find x.
Reference angle = 52°
Opposite side to reference angle = x
Adjacent side = 35
Apply TOA:
Tan 52° = Opp/Adj
Tan 52 = x/35
35 × Tan 52 = x
44.7979571 = x
x = 44.80 (to 2 decimal places)

Home heating oil is sold by the gallon. Last winter, the Romano family used 370 gallons of oil at $2.56 per gallon. If the price increases 9% next year, what will their approximate heating expense be ? Round to the nearest ten dollars .
Answer:
$1030
Step-by-step explanation:
Last winter:
Total expense = 370 * 2.56 = $947.2
Next year,
price increases 9% per gallon
which means, per gallon cost is $2.7904
Approx. expense = 370 * 2.7904 = $1032.448 which is round down to $1030

The answer is D.............
the gradiant y=2x³-5x+1 at point (2,7)
Given:
The equation of the curve is:
[tex]y=2x^3-5x+1[/tex]
To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,
[tex]y=2x^3-5x+1[/tex]
Differentiate the given equation with respect to x.
[tex]y=2(3x^2)-5(1)+(0)[/tex]
[tex]y'=6x^2-5[/tex]
Now we need to find the value of this derivative at (2,7).
[tex]y'_{(2,7)}=6(2)^2-5[/tex]
[tex]y'_{(2,7)}=6(4)-5[/tex]
[tex]y'_{(2,7)}=24-5[/tex]
[tex]y'_{(2,7)}=19[/tex]
Therefore, the gradient (slope) of the given curve at point (2,7) is 19.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 8 N acts on a certain object, the accelerstion of the object is 4 m/s2. If the acceleration of the object becomes 9 m/s?, what is the force?
8N = 4m/s^2
2N = 1m/s^2
18N = 9m/s^2

I need help with Algebra 2. Thank you! :)
Answer:
B: 6.0
Step-by-step explanation:
-3t^2+9t+54 = 0
This is the equation that needs to be solved
Divide both sides by -3
t^2 - 3t - 18 = 0
The factors of 18 are: (1 18) (2 9) (3 6)
3 - 6 = -3 and 3 x -6 = -18
So: (t + 3) (t - 6) = 0
t = -3, 6
It can't be negative so the answer is 6

Nick is making bread.
He needs 103 cups of flour to make one whole loaf of bread.
He has 53 cups of flour.
Use the drop-down menus to complete the statements below about the bread that Nick can make.
Answer:
Well, I can't see the drop-down options but with that amount of flour, I suppose he could make one half of a loaf but he can't make an entire loaf.
Edit:
The answers for the drop-down options:
1.) Nick can make less than one whole loaf of bread.
2.) Nick can make exactly 1/2 loaf of bread with the flour he has.

A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
350 = 12(x + 20) to represent this situation. Solve the equation for x.
• Show your work or explain your answer.
Write your answer as a sentence that describes what the variable x represents.
Answer:
Step-by-step explanation:
350=12(x+20)
(divide both sides by 12)
29.1667=x+20
(subtract 20 from both sides)
x=9.16667
X (9.17) is the additional amount of money the student must save each month in order to reach his goal.
