An object is launched from a platform.

Mathematics
1 answer:
Bess [88]4 years ago

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

h=h(x)=-5x^2+20x+60

where x is the time (in seconds) passed after the launch.

The time of launch is x=0 (0 seconds passed after the launch)

Substitute x=0 to find the height:

h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet

0/1 Autumn's dog eats the same amount of dog food every day. On day 3, the bag of dog food has 12 pounds of dog food. On day 7,
erma4kov [3.2K]

Answer:

y - 0.5x

Step-by-step explanation:

Given that the dog eats the same amount of food each day and on day 3, the available quantity of food

= 12 pounds

On day 7 (4 days after), the available quantity of food is 10 pounds. The difference in the amount of food in 4 days

= 12 - 10

= 2 pounds

This means that each day, the amount of food eaten by the dog in one day

= 2/4

= 0.5 pound

Hence the amount of dog food in the bag y for any day after opening the dog food x will be given as

= y - 0.5x

7. Suppose that y varies inversely with x. Write an equation for the inverse variation,
lys-0071 [83]

Answer:

The answer is

<h2>y =  \frac{24}{x}</h2>

Step-by-step explanation:

The statement

y varies inversely with x is written as

y =  \frac{k}{x}

where k is the constant of proportionality

To find k substitute the values of x and y into the equation

From the question

y = 4

x = 6

We have

4 =  \frac{k}{6}

Cross multiply

k = 4 × 6

k = 24

So the formula for the variation is

<h2>y =  \frac{24}{x}</h2>

Hope this helps you
