Camilia wants to attach a string of lights around the perimeter of her patio for a party but does not want to include the side with the steps. Write a linear expression that represents the length of the string in feet she will need. Then find the length if x = 4.

Answer:

point-slope:x-y+3

slope-intercept: y=x-3

Answer:

Step-by-step explanation:

There is an error in the question.

x + y = 25 is NOT the equation of a circle.

It should be x^2 + y^2 = 5^2.

Parametric equations for the circle:

x = 5cosθ

y = 5sinθ

After 1 second, the object is at (4,3), so θ=arctan(3/4).

At 2 seconds, θ=2arctan(3/4). The object is at (5cosθ,5sinθ) = (1.4, 4.8).

At 3 seconds, θ=3arctan(3/4). The object is at (-1.76, 4.68).

360°/arctan(3/4) ≈ 9.764

The object returns to (5,0) after 9.764 seconds.

Problem 1

Two things you could measure is a person's height and the speed needed to reach the planet Mars. The person's height can be measured with a low level of precision, which means we don't need to be that accurate. We could say "that person is about 6 feet tall" and whoever is listening would get a sense of their height. In contrast, we need high precision for a rocket speed to Mars because getting this figure wrong would likely cause disaster down the road. Very complicated mathematics is essential to make sure we hit the target required in space.

===============================================

Problem 2

As mentioned, we need high precision when it comes to anything dealing with space travel. If the calculations are wrong, then the spacecraft could crash somehow. As one example where things went wrong, engineers used the wrong values and the Mars lander ended up crashing into the planet rather than landing safely. The high cost of such space exploration missions means that it's very crucial to get precise values as much as possible, to as accurate as possible. Things like discussing a person's height isn't that essential to be very precise as we can just relay estimates to whoever we're talking to. This informal setting doesn't demand as much accuracy compared to something like a rocket launch.

Answer:

C) Do the inverse or opposite operations

Step-by-step explanation:

Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.

Answer:

The previous number keeps getting multiplied by - 2

64 ×-2 = -128

-128 × -2 = 256

256 × -2 = -512

Answer:

D. 9 + 4√5

Step-by-step explanation:

What we're essentially doing here is squaring 2 + √5. (2 + √5 and 2 + 1√5 are essentially the same)

(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)

Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5

4 + 2√5 + 2√5 + (√5)²

Step 2: Combine 2√5 and 2√5 to get 4√5.

4 + 4√5 + (√5)²

Step 3: The square of √5 is 5.

4 + 4√5 + 5

Step 4: Add 4 and 5 to get 9.

9 + 4√5 is the final answer to this question.

Answer:

P is greater than -8

P is less than -5

When the circle is hollow that means its never equal to  

When the circle is full it means its equal to

it matters which direction the line is going  

if it goes to the right and it is hollow that it is greater than  

if goes to the left and it is hollow it is less than the number the circle is on  

If the circle is full when it goes to the right then that means its greater than or equal to from the number its going from  

same thing to the left

Answer:

b - 0.60b

= 0.40b

Step-by-step explanation:

The expression would be

here the original cost is b

And Juan sells it for 60% less than original price

So the expression is

= b - 0.60b

= 0.40b

This would be the expression that shows the selling price of the boat

Answer:

29

Step-by-step explanation:

We can use the pythagorean theorem to find the length of the ladder

[tex] {20}^{2} + {21}^{2} = c {}^{2} [/tex]

[tex]400 + 441 = {c}^{2} [/tex]

[tex]841 = {c}^{2} [/tex]

[tex]c = 29[/tex]

The answer is 29

Answer:

x = -2 is a function

Step-by-step explanation:

To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1

we have this as:

Let us try the value x = -2

-2^5 + 2(-2)^4 - 2 + 2

= -32 + 32 - 2 + 2 = 0

This means that the term x = -2 is a root of the equation

Answer:

one yard is equal to 3 feet so

Answer:

This function is a continuous linear function that's domain is all positive real numbers.

Step-by-step explanation:

This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.

It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.

The domain is all positive real numbers since time/years can not be negative.

Answer:

x = 29.4

y = 17

Step-by-step explanation:

sin 90° / 34 = sin 60° / x

x = 34·sin 60°

x = 29.4

sin 90° / 34 = sin 30° / y

y = 34·sin 30°

y = 17

Answer:

z is 95 degrees.

Step-by-step explanation:

Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.

Also in the first question P = 30, because 2(30) + 30 = 90

Answer:

x is less than or equal to negative 14.

Step-by-step explanation:

so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side

remove 5 from each side

-x/3=1/3-5

-x/3=14/3

multiply both sides by 3

-x=14

x=-14

so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14

Answer:

  35 feet square

Step-by-step explanation:

The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.

  70 = 2·35

  525 = 15·35

__

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.

  525/70 = 7 r 35

  70/35 = 2 r 0 . . . . . 35 is the GCD
