Okay, let me first explain what the equation y = 8.77x + 686 means

y is the hikers elevation

Look at the graph and see what the y and x axis's are labeled as.

x is time.

8.77 is just the slop of the trend line.

686 is just the elevation the hiker starts at, or in technical terms, the y intercept. Y intercept is just where the lines touches the y axis.

The question asks what will be the hiker's elevation at 145 minutes.

To solve, just simply plug in 145 as X in the equation above. Remember x is time.

It will look like this :

y = 8.77 (145) + 686

Then solve.

y = 1271.65 + 686

y = 1957.65

Reminder: They want the nearest whole number!

Round 1957.65 feet to 1958 feet

One day, a pet supply store selected every 20th person on a customer list and asked each how many dogs he or she had at home. Te

BARSIC [14]

To find the number of dogs per customer on average, simply divide the total number of dogs by the number of customers that were asked. So we have 2+1+3+2+2+1+4+0+1+4/10 = 2. Hence the answer is 2.

Compute the total cost of the meal to the nearest cent: meal costs $24.62 plus 6% tax and 15% tip.

matrenka [14]

The total cost of the meal is $30.02

Step-by-step explanation:

Given,

Cost of meal = $24.62

Tax = 6%

Tax amount = 6% of cost of meal

$Tax\ amount=\frac{6}{100}*24.62\\Tax\ amount=\frac{147.72}{100}\\Tax\ amount=\$1.48$

Cost after sales tax = 24.62+1.48 = $26.10

Tip = 15%

Tip amount = 15% of cost after sales tax

$Tip\ amount=\frac{15}{100}*26.10\\\\Tip\ amount=\frac{391.5}{100}\\Tip\ amount=\$3.92$

Total cost of meal = Cost after sales tax + Tip amount

Total cost of meal = 26.10+3.92 = $30.02

The total cost of the meal is $30.02

Is domain of f(x,y) = 1 + (4 -y^2)^1/2 open, closed or neither is it bounded or unbounded?

omeli [17]

Answer:

Closed and Bounded.

Step-by-step explanation:

Hi there!

1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:

$f(x,y) = 1 + (4 -y^2)^{\frac{1}{2}} \:id\:est\:f(x,y)=1+\sqrt{(4 -y^2)}$

Since every quadratic root are defined for values $\geq$ 0 then, this help us to understand that we need calculate what interval this Domain is:

$4-y^{2} \geq 0\\4-y^{2}-4\geq -4\\-y^{2}\geq-4 \\y^{2}\leq4\\-2\leq y\leq 2$

$D=[-2,2]$

2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.

Bounded functions have all of their points contained by some circle origin centered. Check it out below.
