Answer 1

Answer:

Answer:

The answer to your question is Perimeter = 24.1 u

Step-by-step explanation:

Data

F (-4, 5)

G (1, 10)

H (-9, 10)

Process

1.- Calculate the distance from FG

dFG = $\sqrt{(1 + 4)^(2) + (10 - 5)^(2)}$

dFG = $\sqrt{5^(2) + 5^(2)}$

dFG = $√(25 + 25)$

dFG = $√(50)$

dFG = $5√(2)$ = 7.07

2.- Calculate the distance from GH

dGH = $\sqrt{(-9 - 1)^(2) + (10 - 10)^(2)}$

dGH = $\sqrt{10^(2) + 0^(2)}$

dGH = $√(100)$

dGH = 10

3.- Calculate the distance from FH

dFH = $\sqrt{(-9 + 4)^(2) + ( 10 - 5)^(2)}$

dFH = $\sqrt{-5^(2)+ 5^(2)}$

dFH = $√(25 + 25)$

dFH = $√(50)$

dFH = $5√(2)$ = 7.07

4.- Calculate the perimeter

Perimeter = 7.07 + 10 + 7.07

= 24.1 units

Scott puts some sports in rowhe makes 6 rows with 5 stickers in each row.If he puts the same number of stikers in 5 equal row how many stickers would be in each row? How do you know

Answers

We know that Scott has put 6 rows with 5 stickers each.

The total number of stickers available with Scott = 5*6 = 30 stickers

These 30 stickers are now placed in 5 rows with equal number of stickers in each row.

Number of stickers in each row= Total number of stickers available/number of rows

Number of stickers in each row = 30/5 = 6 stickers

Number of stickers in each row now would be = 6 stickers

Using complete sentences, explain the key features of the graph of the sine function.

Answers

The trigonometric functions have features that are worthy of note. Among these features are the period and amplitude. The graph of f(x)=sin x repeats itself along the x-axis by a certain distance. This distance is called the period. For the sine function, the period is 2pi radians. It can also be observed that the graph goes up and then down by a certain distance. This distance is called the amplitude. For the curve of f(x)=sin x, the amplitude is 1.

Alex has $30,000 in his savings account that earns 10% annually. How much interest will he earn in on year?

Answers

Answer:

The interest he earns in one year is $3000

Step-by-step explanation:

We are given

Alex has $30,000 in his savings account that earns 10% annually

so,

P=30000

r=10%

t=1 years

now, we can find interest

$I=(P* r* 1)/(100)$

now, we can plug values

$I=(30000* 10* 1)/(100)$

now, we can simplify it

$I=3000$

So,

The interest he earns in one year is $3000

shella is participating in a multi-day bike trip. on the first day, she rode 100 miles in 8 hours. use the expression d/t where d is the distance traveled and t is the travel time to find her average rate of travel. include units when evaluating the expression.

Answers

To solve this problem, first we have to substitute our integers in for our variables in the equation we are using.

d/t= 100 miles/8 hours

Then, we have to simplify the integer equation.

100 miles/8 hours = 12.5 miles per hour

This means that Shella traveled at an average speed of 12.5 mph on her bike trip.

first let's change the "x1" to "A" Nd the "x2" to "B" __ so now the problem reads "6A + 3B = 60" And "6A - 2B= 80" we want to isolate variable. and the easiest one is the "B" by getting rid of the "A". set up a subtraction problem where you take one equation away from the other. 6a-6a=0. 3b - (-2b) = 5b and 60-80=-20. so your new equation reads 5B= -20. you wanna get B on one side so yu divide 5 on both sides giving you b= -4 or "x2"=-4. from there you can plug -4 into any one of the original equations. ex: 6A -2(-4)=80 then 6A + 8=80 then you subtract 8 from both sides because you're trying to isolate the "A" variable. which leaves you with 6A = 72. and now you wanna get"A" on one side so yu divide 6 from both sides and get A=12 or "x1"=12. do a quick check and plug in these numbers into any one of the equation.
