What is the distance between the points (1, -4) and (1, 0)

tino4ka555 [31]

For this case we have that the distance between two points is given by:

$d = \sqrt{(y2-y1)^2+(x2-x1)^2}$

Given the points:

$(x1, y1) = (1, -4)(x2, y2) = (1,0)$

We substitute in the formula:

$d = \sqrt{(0 - (- 4)) ^ 2 + (1-1) ^ 2}$

$d = \sqrt{(4 ^ 2 + 0 ^ 2)}$

$d=\sqrt{16}$

$d = 4$

So, the distance is $d = 4$

Answer:

$d = 4$

Christopher has breakfast at a cafe and the cost of his meal is $36.00. Because of the service, he wants to leave a 10% tip.

Fofino [41]

The cost of his meal at a cafe is $36.00 and Cristofer wants to leave a 10% tip. So to find what is his total bill, you have to count 10% from $36.00.

Note that

$36.00 -- 100%,

$x -- 10%.

Write aproportion:

$\dfrac{\$36.00}{\$x}=\dfrac{100\%}{10\%}.$

Then

$\$x=\dfrac{\$36.00\cdot 10\%}{100\%}=\$3.60.$

Therefore, the total bill consists of $36.00 for the meal and $3.60 tip:

$36.00 + $3.60 = $39.60.

Answer: $39.60

Sarah inherited a sum of 1,539 dollars with an interest rate of 1% per year what is the accrued value after 5 years, 10 years, a

JulijaS [17]

Answer:

See explanation

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest,

P = principal,

r = rate (as decimal),

t = time

In your case,

$P=\$1,539\\ \\r=0.01$

If $t_1=5$ years, then

$I_1=1,539\cdot 0.01\cdot 5=76.95$ and the whole sum is $\$1,539+\$76.95=\$1,615.95$

If $t_2=10$ years, then

$I_2=1,539\cdot 0.01\cdot 10=153.9$ and the whole sum is $\$1,539+\$153.9=\$1,692.9$

If $t_3=15$ years, then

$I_3=1,539\cdot 0.01\cdot 15=230.85$ and the whole sum is $\$1,539+\$230.85=\$1,769.85$

For the expression 6 + y − 3, determine the coefficient for the variable term.

Aleksandr-060686 [28]

6 + y - 3

We cans simplify that to:

y + 3

The coefficient is the number in front of the variable. y is nothing by 1y. So the coefficient is 1.

The variable is y.
The constant is the number without the variable, which is 3.

The answer you are looking for is 1, which is the coefficient.

You are saving money for a summer camp that costs $1800. You have saved $500 so far, and you have 14 more weeks to save the tota

Arlecino [84]

Answer:

$92.86

Step-by-step explanation:

Since it's AT LEAST 1800, the inequality sign would be ≥ 1800

Equation:

500 + 14x ≥ 1800

14x ≥ 1800 - 500

14x ≥ 1300

x ≥ 92.86
