A dolphin dives down into the ocean and resurfaces along a path that is modeled by x^2- 8x + 4y = 0, where the distances are in feet. How many feet is the dolphin from its starting point along the
water's surface?
8 feet
6 feet
4 feet
O feet
please guys i need help

Answers

Answer 1

Answer:

6ft

Step-by-step explanation:

Answer 2

The Dolphin is 8 feet apart from starting point along the water surface.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Equation: x²- 8x + 4y = 0

Now, solving for variable 'y' we get

y= (8x - x²) /4

y= 2x - x²/4

So, the Dolphin is 8 feet apart from starting point along the water surface.

The expression of sinU as a fraction is 12/13

Find the diagram attached.

To get the fraction represented by sinU, we will use the SOH CA TOA identity.

From the diagram;

Hypotenuse = SU = 13Opposite = ST = 12 (angle opposite to m<U)

Since sin theta = opp/hyp

SinU = ST/SU

SinU = 12/13

Translate and simplify: the product of –12 and the difference of p and q.

Answers

Hey there!

“Product” is multiplication so let’s say it means “multiply” & “difference” is subtraction so let’s say it means “subtract”

p & q is/are the variables, whereas -12 is a coefficient

“The [PRODUCT of -12] and the [DIFFERENCE of p & q]”

Product = multiply/multiplication

“-12 ×”

DIFFERENCE

“p - q”

So, based on that information we have your answer: “-12 × p - q”

Rob has dimes and quarters in a jar the ratio of dimes to quarters is 3 to 7 the jar contains 47 quarters what is the total amount of money in the jar.

Answers

Summarize given information. For every 7 quarters, theres three dimes. So divide 47 by 7 and multiply by 3 to find the amount of dimes. If there is a remainder left, further action must be taken.

47 / 7 = 6 (with remainder left over)  

In this case, only 42 would work therefore there are 5 extra quarters left. based on the number 6, there are 18 dimes and 42 quarters. Based on further calculations, of the five quarters left, there should be 2 dimes. So, the amount should become 20 dimes and 47 quarters leaving the percentage of 2.2 quarters per dime in this instant.

20 Dimes = $2

47 Quarters = $11.75

11.75 + 2 = 13.75

So there is about $13.75 in the jar.

Part D: Your parents put in fencing around the walkway for safety. If 110 feet of
fencing is used, what are the dimensions of the pool? Show your work.

Answers

Answer:

Step-by-step explanation:

Not near enough information to know.

I ASSUME that the pool is surrounded by a walkway of constant width (w = 2 ft, from comments)

The pool shape is important as well. No mention of  the shape

If the pool is circular and the walkway is 3 ft wide

the fence encloses a diameter of 110/π = 35 ft

so the diameter of the pool would be 35 - 2(3) = 29 ft.

POOL IS RECTANGULAR from comments

If the pool is square and the walkway is 2 ft wide, each side of the fence is

110 / 4 = 27.5 ft and the pool would be 27.5 - 2(2) = 23.5 ft on a side.

There are an infinite number of rectangular width and length dimensions and walkway dimensions which would result in a fence length of 110 ft.

Edit from comments

Still an infinite number of rectangular length an width dimensions for a pool with a 2 ft wide walkway around it.

Let's say that we are told the pool is 12 ft wide with 2 ft walkway.

Let L be the pool length

110 = 2(12 + 2(2)) + 2(L + 2(2))

110 = 32 + 2L + 8

70 = 2L

L = 35 ft

what equation is equivalent to 7-2x=5

Answers

Answer:

x = 1New equation: 7 - 2 = 5

Step-by-step explanation:

7 - 2x = 5=> 7 - 5 = 2x=> 2 = 2x=> x = 1

Conclusion:

Since:

x = 1

Our new equation will be 7 - 2 = 5

Hoped this helped.

Hey there!

7 - 2x = 5

-2x + 7 = 5

SUBTRACT 7 to BOTH SIDES

-2x + 7 - 7 = 5 - 7

CANCEL out: 7 - 7 because that gives you 0

KEEP: 5 - 7 because it helps solve for the x-value

NEW EQUATION: -2x = 5 - 7

SIMPLIFY IT!

-2x = -2

DIVIDE -2 to BOTH SIDES

-2x/-2 = -2/-2

CANCEL out: -2/-2 (on the LEFT SIDE) because that gives you 1

KEEP: -2/-2 (on the RIGHT SIDE) because it helps you solve for the x-value

NEW EQUATION: x = -2/-2

SIMPLIFY IT!

x = 1

Therefore, your answer should be: x = 1

Checking to make sure it is correct!

-2x + 7 = 5

-2(1) + 7 = 5

-2 + 7 = 5

So, this makes this statement TRUE
