Answer:

35 feets

Step-by-step explanation:

Initial Position = - 25 feets

Final height reached after jumping = 10 feets

The vertical distance traveled by dolphin :

Final height reached - Initial position

(10 feets) - (-25 feets)

10 feets + 25 feets

= 35 feets

Answer:

d = 2

Step-by-step explanation:

14d - 22 +5d = 12d - 8

19d -22 = 12d - 8

      +22         +22

    19d = 12d + 14

  -12d   -12d

     7d = 14

    /7       /7

      d = 2

Answer:

d = 2

Step-by-step explanation:

Simplifying

14d + -22 + 5d = 12d + -8

Reorder the terms:

-22 + 14d + 5d = 12d + -8

Combine like terms: 14d + 5d = 19d

-22 + 19d = 12d + -8

Reorder the terms:

-22 + 19d = -8 + 12d

Solving

-22 + 19d = -8 + 12d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-12d' to each side of the equation.

-22 + 19d + -12d = -8 + 12d + -12d

Combine like terms: 19d + -12d = 7d

-22 + 7d = -8 + 12d + -12d

Combine like terms: 12d + -12d = 0

-22 + 7d = -8 + 0

-22 + 7d = -8

Add '22' to each side of the equation.

-22 + 22 + 7d = -8 + 22

Combine like terms: -22 + 22 = 0

0 + 7d = -8 + 22

7d = -8 + 22

Combine like terms: -8 + 22 = 14

7d = 14

Divide each side by '7'.

d = 2

Simplifying

d = 2

Answer:

root3/ root2

Step-by-step explanation:

since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.

B = C / root2

x = root3 / root2

Answer:

y=4x-1

Step-by-step explanation:

We know that the slope equation is y=mx+b. M is the slope and B is the y-intercept. M is provided to be 4 and B is provided to be -1, so all we have to do is plug them in to get the answer.

Answer:

y = 4x - 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = price + 0.1*price

cost = 1.1 * price

price = cost / 1.1

price = 22 / 1.1 = 20

now we need 20% of that so that's

20 * 0.2 = 4

If she's simple-minded enough to tip that would amount to $4

Answer:

The function would be linear because the rate of change is constant.

Step-by-step explanation:

Given

[tex]Base= \$89.00[/tex]

[tex]Rate = \$0.10[/tex] per minute

See attachment for complete question and options

First, we write the function that calculates the cost (C(t)) for t minutes.

This is calculated as:

[tex]Cost = Base + Rate * t[/tex]

[tex]C(t) = 89.00 + 0.10 * t[/tex]

[tex]C(t) = 89.00 + 0.10t[/tex]

Rewrite as:

[tex]C(t) = 0.10t + 89.00[/tex]

A function that has the above format is referred to as a linear function which has the general format

[tex]f(x) = mx + b[/tex]

Where

m represents the slope/rate and it is constant

From the list of given options, (a) is correct.

Answer:

p = 2 or p = -2

Step-by-step explanation:

Solve for p over the real numbers:

16 p^2 - 64 = 0

Hint: | Factor constant terms from the left hand side.

16 p^2 - 64 = 16 (p^2 - 4):

16 (p^2 - 4) = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 16:

p^2 - 4 = 0

Hint: | Using the quadratic formula, solve for p.

p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:

Answer: |  

| p = 2 or p = -2Solve for p over the real numbers:

16 p^2 - 64 = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 16:

p^2 - 4 = 0

Hint: | Using the quadratic formula, solve for p.

p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:

Answer:

Negative

Step-by-step explanation:

Think about it this way, you cannot do something positive and then do something negative and it still be positive. You cannot do something negative and then do something positive for it to be positive. But you can do something positive and do something else positive for it to remain positive the same with negative. Therefore the answer is "negative."

Rules:

Positive ÷ Negative = Negative

Positive × Positive = Positive

Negative ÷ Negative = Positive

Answer:

$5.13

Step-by-step explanation:

Answer:

$5.13 :)

Step-by-step explanation: the second number after the decimal is the hundredths place :)

Answer:

23/5

is the 4.6 fraction

The decimal 4.6 is equivalent to the fraction 23/5.

The whole number part of the decimal, which is 4, will be the numerator of the fraction.

The decimal part, which is 0.6, will be the numerator of the fraction divided by the appropriate power of 10.

In this case, the decimal has one digit after the decimal point, so we divide it by 10¹.

0.6 / (10¹)

= 0.6 / 10 = 6/10

Simplify the fraction if possible.

Both the numerator and denominator can be divided by their greatest common divisor, which is 2 in this case.

6/10 = (6/2) / (10/2) = 3/5

Therefore, the decimal 4.6 is equivalent to the fraction 4 3/5 or simply 23/5 after simplification.

Answer:

they are parallels

Step-by-step explanation:

they have the same slope but different y intercepts so they are parallel

Answer:

Parallel

Step-by-step explanation:

First, you should put the second equation in slope-intercept form, it would be y=3x+8.

If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.
