A bird drops a stick to the ground from a height of 70ft. The function h = -16t^2 + 70 gives the​ stick's approximate height h above the​ ground, in​ feet, after t seconds. Graph the function. At about what time does the stick hit the​ ground?

Answers

Answer:

√ 80/16=t t=0.5590169943749474

Step-by-step explanation:

The function h(t) = -16t^2 + 70 is a quadratic function, and the stick hits the ground at about 2.092 seconds

Here, we have,

to determine the time it hits the ground:

The function is given as:

h(t) = -16t^2 + 70

Next, we plot the graph of the function h(t)

From the graph of the function h(t) (see attachment), we have the following highlight:

t = -2.092 and t = 2.092 when h(t) = 0

Time cannot be negative.

So, we have:

t = 2.092

This means that the stick hits the ground at about 2.165 seconds

when 25 percent is allowed,a customer pays Rs 1680 to buy a watch.Find the cost of the watch before the discount.​

Answers

Answer:

nobody knows, go to a shop

Step-by-step explanation:

Cost price percentage =100%
Percentage discount =25%
Therefore percentage that the customer bought = 100 - 25= 75%

If 75% = Rs 1680
then 100% =100 x 1680/75
= Rs 2240
Hence the cost of the watch before discount is Rs 2240

Answers

Billy's total annual health insurance premium is $4,712.54. Then the correct option is D.

What is the percentage?

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Billy’s employer pays for 65% of his annual health insurance premium.

Billy has the rest deducted in equal amounts from his paycheck.

If billy has $105.73 withheld from his paychecks twice each month.

His employer contributes towards his health insurance on an annual basis.

To get the amount of his employer to contribute towards his health insurance on an annual basis will be

105.73 × 24 = 2537.52

The next step is to calculate Billy's total annual health insurance premium will be

[tex]\rm Health \ insurance \ premium = \dfrac{2537.52 * 0.65}{0.35}\\\\Health \ insurance \ premium = 4712.54[/tex]

What is Algebra?

Algebra is a branch of mathematics that deals with symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables. In our real-life problems, we often see certain values that keep on changing. But there is a constant need to represent these changing values. Here in algebra, these values are often represented with symbols such as x, y, z, p, or q, and these symbols are called variables. Further, these symbols are manipulated through various arithmetic operations of addition, subtraction, multiplication, and division, with an objective to find the values.

Algebraic Expressions

An algebraic expression in algebra is formed using integer constants, variables, and basic arithmetic operations of addition(+), subtraction(-), multiplication(×), and division(/). An example of an algebraic expression is 5x + 6. Here 5 and 6 are fixed numbers and x is a variable.

Given:

John is 3 years older than Mary.

Five years ago he was four times as old as Mary was then.

let the age of mary be x

John's age= x+ 3

Five years age,

Mary's age= x-5

john's age = x-2

So,

x-2= 4( x-5)

x- 2 = 4x- 20

-3x= -18

x=3

Hence, john's age= 9 years

ロ The perimeter is 37.5 ft.
ロ The area inside the fenced in section is 60 sq ft
ロ The area inside the fenced section is 68 sq ft.

Answers

The missing side of the fence measures 15 ft

The perimeter of the fence is 40 ft

The area inside the fenced in section is 60 ft²

The fence is triangular and a right triangle.

Right triangle:

A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.

c² = a² + b²

17² - 8² = b²

b = 15 ft

AC = 15 ft

perimeter of the triangle = 15 + 8 + 17 = 40 ft

Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²

Therefore,

The missing side of the fence measures 15 ft

The perimeter of the fence is 40 ft

The area inside the fenced in section is 60 ft²

At an intersection, the red-light times are normally distributed with a mean time of 3 minutes and a standard deviation of 0. 25 minutes. Using the empirical rule, approximately what percent of red lights last between 2. 5 and 3. 5 minutes? 32% 68% 95% 99. 7%.

Answers

The red light lasts between 2.5 minutes and 3.5 minutes is 95 %. Then the correct option is C.

What is normal a distribution?

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

At an intersection, the red-light times are normally distributed with a mean time of 3 minutes and a standard deviation of 0. 25 minutes.

In this case, the mean is 3 and the standard deviation is 0.25, We move one space to the right that would represent 3.25 minutes, one more space to the right that is 3.50 minutes. Similarly, we move one space to the left, this would be 2.75, one more space to the left, and the shows 2.50 minutes.

Thus, the correct option is C.

what's 5 divided by 3 1/3?

Step-by-step explanation:

We can start by converting 3 1/3 to an improper fraction. Since 3 is equal to 9/3, 3 1/3 would be equal to 9/3 + 1/3 = 10/3.

Therefore, we are doing [tex]\frac{5}{\frac{10}{3}}[/tex].

Dividing 5 by 10/3 is the same as multiplying 5 and the reciprocal of 10/3, which is 3/10.

5*3/10 = 15/10 = 3/2.
