A toy company is releasing a new catapult for water balloons that launches them at 9.8 meters per second from a stand 0.6 meters

tall. The function f(x) = −4.9x2 + 9.8x + 0.6 describes the path of the water balloon, where x is the amount of time since the launch. While the mathematical range is y ≤ 5.5, how does the reasonable range compare? The reasonable range is limited to y ≥ 0. The reasonable range is limited to y ≥ 0.6. The reasonable range is limited to 0 ≤ y ≤ 5.5. The reasonable range is limited to 0.6 ≤ y ≤ 5.5.

Andreyy89

Answer: 5%

Step-by-step explanation:

First and foremost, we need to know that 60 minutes = 1 hour. Therefore,

7 hours = 60 × 7 = 420 minutes.

Number of minutes awake = 21 minutes

Number of minutes supposed to be asleep = 7 hours = 420 minutes

The percentage of the seven hours that Frank was awake during the night will be:

= 21/420 × 100

= 1/20 × 100.

= 5%

Vanyuwa [196]

Answer:

(B) The citizens of the city, because they lose help they could have used to buy a home.

Step-by-step explanation:

Nul and alternative hypotheses are:

  • H_{0}: the rate of home ownership is the same after tax cut
  • H_{a}: the rate of home ownership is increasing after tax cut

Type II error occurs when one fails to reject null hypothesis when the null hypothesis was wrong.

In this case Type II error happens when the conclusion is the rate of home ownership is not increasing after tax cut, where actually it is.

With this conclusion city council does not continue tax cut, and citizens of the city is harmed because they lose help they could have used to buy a home.

Please help explanation if possible
Nookie1986 [14]

Answer:

y=-3x+5

Step-by-step explanation:

concepts: y=mx+b is slope intercept equation formula

m=slope

b= y intercept

Therefore we need to find the slope and y intercept

first find slope

m=\frac{y2-y1}{x2-x1}

let y2 be 2

let y1 be -4

let x2 be 1

let x1 be 3

\frac{2-(--4)}{1-3}

6/-2 = -3

m=-3

slope is -3

y= -3x+ b

we need find y intercept now

just plug in (1,2) into that equation

2=-3(1)+b

b=5

y=-3x+5

The difference between two numbers is 25. The smaller number us 1/6th of the larger number. What is the value of the smaller num
Nataliya [291]

Answer:

5

Step-by-step explanation:

Let L be the larger number and s be the smaller one.

Then we have two equations.

(1) L – s = 25

(2)       s = L/6     Multiply both sides by 6

        6s = L         Substitute the value for L in Equation(1)

 6s – s = 25        Combine like terms

       5s = 25        Divide both sides by 5

         s = 5

The value of the smaller number is 5.
