A construction worker drops a hammer while building the Grand Canyon skywalk 4,000ft above the Colorado River. Use the formula t=h−−√4 to find how many seconds it takes for the hammer to reach the river. Round your answer to the nearest tenth of a second.

Answers

Answer:

15.8

Step-by-step explanation:

We are asked to find how many seconds it takes for an object to fall from a height of 4,000ft. We will use the given formula, t=h−−√4. Substituting h=4,000, we find

t=4000−−−−√4=15.8

So, the hammer reaches the river after 15.8 seconds.

If y varies directly as x and y =6 when x =2 ... find y when x=9

Answers

Answer:

27

Step-by-step explanation:

y = kx, where k is the constant of proportionality.  If x = 2 and y = 6, that constant is determined as follows:

6 = k(2), or k = 3.  Then y = 3x.  When x = 9, y = 27

Solve by factoring

Answers

Answer:

x= −1/4 or x = 5

Step-by-step explanation:

Step 1: Factor left side of equation.

(4x+1)(x−5)=0

Step 2: Set factors equal to 0.

4x+1=0 or x−5=0

Answer:

x= −1/4 or x = 5

The factored form of the equation  4x²- 19x - 5 = 0 is (4x+1)(x-5).

The given equation is 4x²- 19x - 5 = 0.

To factor the quadratic expression on the left-hand side into two binomials.

The binomial factors will have the form (ax + b)(cx + d).

We need to find two numbers whose product is equal to ac (the coefficient of x² term) multiplied by d (the constant term), which is (4)(-5) = -20, and whose sum is equal to the coefficient of the x term, -19.

After considering different factor pairs of -20, we find that -20 and +1 satisfy the requirements.

(4x² - 20x) + (x - 5) = 0.

4x(x - 5) + (x - 5) = 0.

(4x+1)(x-5)=0

Suppose a researcher compiled a data set consisting of the following variables for a sample of 100 retired men. For each variable, select whether it is discrete or continuous. Variable Discrete Continuous The number of meals eaten out in the last week The number of pets currently living in the household Pant size Height in inches Pounds of chocolate consumed in the past year

Answers

Step-by-step explanation:

A discrete variable can be defined as a definite variable that we can get it's possible values just by counting. With this in mind.

1. The number of countries ever visited is a discrete variable

2. Shoe size is definite, it is a discrete variable.

3. Number of pets living in a household is a discrete variable.

A continuous variable is one that we can get the value through measurements.

1. Pounds of chocolate consumed in the past is continuous

2. Height in inches is continuous

Cost of five lemons is $2.
What is the cost per lemon?
Answer: $
per lemon
Part B
At this rate, what is the cost of 9 lemons?

Answers

Answer:

Part a: $0.40 per lemon,  Part b: $3.60

Step-by-step explanation:

Because the cost of five lemons is $2, it would be: 5 lemon = $2

$2/5 lemons = $x/1 lemon

so divide by 5 on the numerator and denominator. 2 divided by 5 = 0.4

So part a: 40 cents or $0.40 per lemon!

Part B:

cost of 1 lemon compared to 9 lemons:

$0.40/1 = x/9

Multiply both numerator and denominator by 9

So, it costs $3.60 for 9 lemons.
