Donetta is investing $6000 in a stock fund that is offering a constant annual interest of 5%.
The interest in investing $6000 in a stock fund that is offering a constant annual interest of 5% is $300
What is interest?
Interest is the amount of money made from investing a particular amount of money over a period of time. It is given by:
I = PRT
I is interest, P is principal, R is rate and T is period
Donetta is investing $6000 in a stock fund that is offering a constant annual interest of 5%. Hence in one year:
I = 6000 * 5% * 1 year = 6000 * 0.05 * 1 = $300
The interest in investing $6000 in a stock fund that is offering a constant annual interest of 5% is $300

Ash company reported sales of $580,000 for year 1, $630,000 for year 2, and $680,000 for year 3. Using year 1 as the base year, what is the revenue trend percent for years 2 and 3??
Answer:
Year 2: 109.4%
Year 3: 118.9%
Step-by-step explanation:
Given;Ash company reported sales of $580,000 for year 1$630,000 for year 2, $680,000 for year 3.Now,
For the revenue trend percent for year 2
Year 2: $580,000 / $530,000 × 100 = 109.4%
For the revenue trend percent for year 3
Year 3: $630,000 / $530,000 × 100 = 118.9%
Thus, The answer is 109.4% and 118.9%.

Angles on a straight line will always add up to 180°
The sum of interior angles in a triangle is 180°
Question 7
a + 134° = 180°
⇒ a = 180° - 134°
⇒ a = 46°
b + 119° = 180°
⇒ b = 180° - 119°
⇒ b = 61°
a + b + c = 180°
⇒ 46° + 61° + c = 180°
⇒ c = 180° - 46° - 61°
⇒ c = 73°
Question 8
r + 126° = 180°
⇒ r = 180° - 126°
⇒ r = 54°
s + 145° = 180°
⇒ s = 180° - 145°
⇒ s = 35°
r + s + t = 180°
⇒ 54° + 35° + t = 180°
⇒ t = 180° - 54° - 35°
⇒ t = 91°

A football is punted from a height of 2.5 feet above the ground with an initial vertical velocity of 45 feet per second.
Write an equation to model the height h, in feet, of the ball t seconds after it has been punted.
The football is caught at 5.5 feet above the ground. How long was the football in the air?
Answer:
1.451 seconds. Hurry.
Step-by-step explanation:
The position(height, h) of the foot ball will be given by the equation:
h = -32.2t^2 + 45t + 2.5
The term -32.2t^2 consists of the acceleration caused by gravity at Earth's surface ( -32 ft/sec^2) and the term +45t accounts for the initial velocity. The + is assigned since the ball is moving vertically from ground. The negative sign in -32t^2 is due to the acceleration being towards ground. The term 2.5 accounts for the fact that the initial height of the ball is 2.5 feet above ground.
We can either calculate or graph with this function to find the time the ball spends in the air:
Calculate:
h = -32.2t^2 + 45t + 2.5
We need a value of t that would cause h to be 5.5 feet, the level it was caught:
5.5 = -32.2t^2 + 45t + 2.5
-32.2t^2 + 45t + 2.5 = 5.5
-32.2t^2 + 45t -3.0 = 0
Solve for t using the quadratic formula. I get a value of 1.33 seconds.
Graph:
See the attached graph. It confirms the 1.33 second value

Answer:
hello
f (2 ) = 6 et f ( 0 ) = 3
( 3 - 6 ) / ( 0 - 2 ) = - 3/- 2 = 3/2
ax = 3 x /2
f (0) = 3 ⇔ b = 3
f (x) = 3 x /2 + 3
also f ( 0) = 0 + 3 = 3
sorry
y = ax + b
b = 3
since the line cuts the y-axis in 3
then for a ? which is the slope..
we take 2 points on the line (0 ; 3) and (2 ; 6)
we move 2 units to the left to go up 3 units
so a = 3/2
=> y = 3/2x + 3
