The number of subscribers y to a magazine after t years is shown by the equation below: y = 95(0.75)t Which conclusion is correct about the number of subscribers to the magazine? It increased by 25% every year. It decreased by 25% every year. It increased by 75% every year. It decreased by 75% every year.
Answers
Answer:
B. It decreased by 25% every year.
Step-by-step explanation:
We have,
Number of subscribers 'y' after 't' years is given by,
i.e.
i.e.
We see that the rate of number of subscribers is -0.25 i.e. -25%.
Since, the rate is negative.
Hence, we get that the number of subscribers are decreasing 25% every year.
if you multiply a number by a decimal you will get a smaller number than you originally had. for example, if you multiply 95 by .75 you will get 71.25 it is decreasing but only 25%

The vertex form of the equation is h(t) = -5 ( t - 2)² + 104.
At its highest point, the brick was 101 meters above the ground.
What is the vertex form of a quadratic function?
The factored form of a quadratic function is given as:
f(x) = a(x – h)2 + k
where a, h, and k are constants.
We have,
h(t) = -5t² + 20t + 105
h(t) = -5 ( t² - 4t ) + 105
h(t) = -5 ( t² - 4t + 2² ) - 2² + 105
h(t) = -5 ( t - 2 )² - 4 + 105
h(t) = -5 ( t - 2 )² + 101 _____(1)
The vertex form of the equation is h(t) = -5 ( t - 2)² + 104.
From equation (1) we can say that at its highest point the brick was at
101 meters above the ground.
Thus,
The vertex form of the equation is h(t) = -5 ( t - 2)² + 104.
At its highest point, the brick was 101 meters above the ground.

We have the hypotenuse and the angle.
We want to find the height.
For this, we use the following trigonometric relationship:
sine (x) = C.O / h
Where,
x: angle
C.O: opposite leg
h: hypotenuse
Clearing C.O we have:
C.O = 85 * sine (45)
C.O = 60.1040764
Round to the nearest tenth of a foot:
C.O = 60 feet
