A diver is standing on a platform 24 ft above a pool. He jumps from the platform with an initial
upward velocity of 8 ft/s. Using the formula, h(t) = -16t2 + vt + s, where h is his height
above the water, t is the time, v is his starting upward velocity, and s is his starting height.
A) After how long will the diver reach its maximum height?
B) What is the maximum height the diver will reach?

Answers

Answer 1

Answer:

he Formula h = -16t^2 + vt + s; where

h = height after t seconds

t = time in seconds

v = upward velocity

s = initial height (t=0)

also note that

-16t^2 represents the downward force of gravity for t seconds

+vt = the upward force for t seconds

:

the height when he hits the water = 0 therefore:

0 = -16t^2 + 8t + 24

usually written

-16t^2 + 8t + 24 = 0

we can simplify this, divide by -8, then we have

2t^2 - t - 3 = 0

this will factor to

(2t - 3)(t + 1) = 0

the positive solution

2t = 3

t = 3/2

t = 1.5 seconds to hit the water

Answer 2

Form the actual equation

y=-16t²+vt+sy=-16t²+8t+24

What is the x-intercept of the line 3x – 7y = 42?
PLEASE HELP

Answers

Answer:   x-intercept = 42/3 = 14

Step-by-step explanation:  y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

Notice that when x = 0 the value of y is 6/-1 so this line "cuts" the y axis at y=-6.00000

 y-intercept = 42/-7 = 6/-1  = -6.00000

When y = 0 the value of x is 14/1 Our line therefore "cuts" the x axis at x=14.00000

 x-intercept = 42/3  =  14

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -6.000 and for x=2.000, the value of y is -5.143. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -5.143 - (-6.000) = 0.857 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.857/2.000 =  0.429

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  3x-7y-42  = 0 and calculate its properties

x-intercept = 42/3 = 14

A baker has a bag with 20 cups of flour. The baker plans to use the flour to make 4 loaves of bread. Each loaf of bread uses cups of flour. How many cups of flour will remain in the bag when the baker is finished?

Answers

Following our assumption, the number of cups that will be remained in the bag after the baker is finished is 4 cups.

Word Problems in mathematics are those methods involving the use of algebra, fractions, ratios, and other basic mathematical concepts to solve problems in real-life cases.

From the given information:

A bag of flour = 20 cupsThe baker plans to make = 4 loavesLet's assume that each flour make use of = 4 cups

Then, the number of cups to make 4 loaves of bread is:

= (4 × 4) cups

= 16 cups to make 4 loaves of bread.

The number of cups of flour remaining will be:

Step-by-step explanation:

mark me brainliest!!

Answer: A

Step-by-step explanation:

Let the length side of the TV = a

The width of the TV = b

The diagonal of a TV = c

In a 30-60-90 right triangle,

We have cos(30°) = [tex]\frac{\sqrt{3}}{2}[/tex] and sin(30°) = [tex]\frac{1}{2}[/tex]

Given that c = 28 inches:

sin(30°) = [tex]\frac{b}{c}[/tex]

[tex]\frac{1}{2} = \frac{b}{c}[/tex]

[tex]b = \frac{1}{2} \times 28 = 14[/tex]

That is, the width of the TV = 14 inches

cos(30°) = [tex]\frac{a}{c}[/tex]

[tex]\frac{\sqrt{3}}{2} = \frac{a}{c}[/tex]

[tex]a = \frac{\sqrt{3}}{2} \times 28 = 14\sqrt{3}[/tex]

That is, the length of the TV = 14√3 inches

So the exact width and length of the TV are 14 inches and 14√3 inches.

Therefore, option A is the correct answer

Analitically.

Collect [tex]9x^4[/tex] in the numerator under the square root, [tex]x^2[/tex] in the denominator.

[tex]\lim\limits_{x \to \infty} \frac{\sqrt{9x^4(1+\frac{1}{9x^4})}}{x^2(1-\frac{3}{x}+\frac{5}{x^2})} = \lim\limits_{x \to \infty}\frac{3x^2\sqrt{(1+\frac{1}{9x^4})}}{{x^2(1-\frac{3}{x}+\frac{5}{x^2})}} = 3[/tex]

Answer:

Step-by-step explanation:

39.75n ≤ 134.25

n ≤ 3.37

The greatest integer less than or equal to 3.37 is 3.

Answer: 3

The maximum number of people who can go to the amusement park will be 3.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that the group has $140 to spend on parking and admission. Parking is $5.75, and tickets cost $39.75 per person, including tax.

For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.

Suppose the number of people will be n.

39.75n + 5.75 ≤ 140

39.75n ≤ 134.25

n ≤ 3.37

The greatest integer value should be less than or equal to 3.37 is 3.

Thus, the maximum number of people who can go to the amusement park will be 3.
