Answer:

0<t<5/4  or B

edge

The interval of time, the acorn moving through the air is t > 5/4.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

An acorn falls from the branch of a tree to the ground below = 25 feet

The equation is [tex]S(t) = -16t^2 + 25[/tex], where t is the number of seconds and

S is the distance.

At t=0,

⇒ [tex]S(0) = -16(0)^2 + 25[/tex]

⇒ [tex]S(0) = 25[/tex]

Initially, the acron is at 25 feet above the ground level. So t > 0, for the acron to fly on air.

The interval can be found as,

⇒ [tex]-16t^2 + 25 > 0[/tex]

⇒ [tex]-16t^2 > -25[/tex]

⇒ [tex]t^2 > \frac{25}{16}[/tex]

⇒ [tex]t > \sqrt{\frac{25}{16} }[/tex]

⇒ [tex]t > \frac{5}{4} or \frac{-5}{4}[/tex]

since t > 0, the interval is [tex]t > \frac{5}{4}[/tex]

Hence we can conclude that the interval of time, the acorn moving through the air is t > 5/4.

Answer:

x^4 +y+1

Step-by-step explanation:

The quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].

The vertex form of a quadratic function is [tex]f(x) = a(x-h)^{2} + k[/tex] where a, h, and k are constants and (h, k ) is the vertex of the graph of the function.

According to the given question we have

The graph has the vertex is (1, 0) and passes through (2, -17)

Since, the general form of a quadratic function in a vertex form  is

[tex]y = a(x-h)^{2}+ k[/tex]

substitute, h = 1 and k = 0 in the above equation

⇒ [tex]y = a(x-1)^{2} +(0)^{2}...(i)[/tex]

Also, the graph passes through the point (2, -17)

⇒ [tex]-17 = a(2-1)^{2}[/tex]

⇒ -17 = a or a = -17

Substitute the value of a in equation (i).

⇒[tex]y = -17(x-1)^{2}[/tex]

Therefore, the quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].

Answer: 55 miles per hour

Step-by-step explanation:

Here is the complete question:

Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.

Find the average speed in miles per hour needed to make the trip in the desired.

From the question, Seth's family plans to drive 220 miles to their vacation spot and they would like to complete the drive in 4 hours.

Average speed is calculated as distance travelled divided by the time taken. This will be:

Speed = Distance/Time

Average speed = 220/4

Average speed = 55 miles per hour

Multiply the number of producers by $ 5,000.00

Question:

Members of a producer association

decided to donate $ 5,000.00 each to improve the production. Than

procedure allows know the total contribution?

A) Divide $ 5,000.00 between the

number of producers

B) Multiply the amount of producers for $ 5,000.00

C) Add the amount of producers plus $ 5,000.00

О

D) Subtract $ 5,000.00 from the amount of producers

Step-by-step explanation:

We are asked to find the total contribution

Each manufacture will contribute $5,000.00

We were not told the number of manufacturers that would be contributing the amount.

Total contribution = number of manufactures × $5000

The procedure that allows one to know the total contribution:

Multiply the number of producers by $ 5,000.00

Option has B stated 'amount' instead of 'number'. It may be a mistake

B) Multiply the amount of producers for $ 5,000.00

Answer:

Radius = 7.21 feet.

Height = 21.63 feet

- to the nearest hundredth.

Step-by-step explanation:

Let the radius be r feet, then the height will be 3r feet.

So the volume = 1,178.1 = 1/3 π r^2 h

1.178.1 = 1/3  π r^2 3r

1/3 π 3 r^3 = 1178.1

 π r^3 = 1178.1

r^3 = 1178.1/ π

r^3 =   375

r = 7.211 feet.

So the height = 3 * 7.211 ft

= 21.633 ft

The question is incomplete:

Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?

Answer:

$24

Step-by-step explanation:

From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:

x+0.05x=25.20

Then, you can isolate x to find the price before tax:

1.05x=25.20

x=25.20/1.05

x= 24

According to this, the price before tax of the food items is $24.

Answer:

The probability is 1/3

Step-by-step explanation:

Here, we are interested in calculating the probability that the spinner will land on the yellow section.

Firstly, we need to calculate the total number of sections. That would be = 2 + 3 + 4 + 3 = 12 sections

Now, the probability that the spinner will land on the yellow section = number of yellow sections/total number of sections

There are four yellow sections

Thus, the probability of the spinner falling on a yellow section = 4/12 = 1/3

For a line with a positive slope that passes through (0, 1), the points that can't be on the line are:

(-3, 1) and (5, -2)

We know that the line passes through the point (0, 1) and has a positive slope. This means that for values of x larger than x = 0, the values of y in the line will be larger than 1.

Then if we find a point with:

x > 0

y ≤ 1

That point clearly can't belong to our line.

And points with:

x < 0

y ≥ 1

Also can't belong to the line.

Then the correct options are: (-3, 1) and (5, -2)
