did you ever fine out the answer to this lol

Step-by-step explanation:

Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t

is measured in seconds. The rate at which the area covered by the oil is changing at time t = 10 is  A'(10).

Given that:

To determine the rate at which the area covered by the oil is changing with time, we need to differentiate  A(t) with respect to time t.

∴

By differentiation:

[tex]\mathbf{\dfrac{dA}{dt} =A'(t)}[/tex]

∴

[tex]\mathbf{\dfrac{dA}{dt} \Big| _{t=10}=A'(t)\Big|_{t=10}}[/tex]

[tex]\mathbf{\dfrac{dA}{dt} =A'(10)}[/tex]

Therefore, we can conclude that the rate at which the area covered by the oil is changing at time t=10 is  A'(10).

Answer:

Step-by-step explanation:

Evaluate x3−y2 if x=2 and y=34

substitute x=2 and y=32 into the expression:

= x3 - y2

= (2)3 - (34)2

= 6 - 68

= -62

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression x³−y², when x=2, y=34 is −1,148.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the expression x³−y² and the value of the expression when x=2 and y=34 can be calculated by substituting the values in the expression. Therefore, the expression can be written as,

x³ − y²

Substitute the value of x and y in the expression,

= (2)³ − (34)²

Opening the bracket,

= 8 − 1,156

= −1,148

Hence, the value of the expression x³−y², when x=2, y=34 is −1,148.

-2-(-4)-2

We can break down the problem first. The beginning of the problem is...

-2-(-4)

Two negatives make a positive. An equivalent way to say this is

-2+4

-2+4=2

Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!

2-2=0

The answer to this is 0!

Answer:

y=10x+28

Step-by-step explanation:

y=10x+28

y=(10*-2)+28

y=-20+28

y=8

The linear equation of the line is y + 2 = 10(x - 8)

The slope is given as:

m = 10

The point is given as:

(x1, y1) = (8, -2)

The equation in point slope form is calculated as;

y -  y1 = m(x - x1)

So, we have:

y + 2 = 10(x - 8)

Hence, the linear equation of the line is y + 2 = 10(x - 8)

Answer:

see explanation

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

(4)

Here d = 18, thus

C = 18π in

(5)

Here C = 50π, thus

πd = 50π ( divide both sides by π )

d = 50 in

The radius r is one half of the diameter , thus

r = 50 ÷ 2 = 25 in

Answer:

11 1/5 feet!

Step-by-step explanation:

He needs a total of 27 9/10 feet! 11 1/2 + 5 1/5 is 16 7/10 feet! If we need 27 9/10 feet, we subtract 16 7/10 ft from 27 9/10 ft to get 11 2/10, which we can reduce 2/10 to be 1/5.

So, he needs 11 1/5 feet of wood more to build the doghouse for his new puppy!

Answer:

  G)  $48,357.57

Step-by-step explanation:

The future value formula can be used to find the account value:

  FV = P(1 +r)^t

where P is invested at annual rate r for t years.

  FV = $50,000(1.07^10) ≈ $98,357.57

The amount of interest earned is the difference between this value and the value of the initial investment:

  interest = $98,357.57 -50,000 = $48,357.57

Hank earned $48,357.57 in interest after 10 years.

_____

At 7% interest, the "rule of 72" tells you the doubling time of the account is about 72/7 = 10.3 years. That is the account value will be not quite double the original investment after 10 years. So, the amount of interest earned is only slightly less than $50,000. If the account earned simple interest, the interest earned would be $35,000. Only one answer choice is more than $35,000 and less than $50,000.

Answer:

3/4 quarts of yellow paint is needed

Step-by-step explanation:

From the question, we are told that:

In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue.

3 quart of Purple paint mix requires 2quarts of red paint and 1 quart of blue paint.

We are also told that:

When George wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio.

This means 1 Purple paint to 1 Yellow paint

4/4 quarts of Yellow paint = 1 yellow paint

3/4 quarts of Yellow paint = 3/4 quarts of purple paint

Answer:

y = -3x - 11

Step-by-step explanation:

Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.

Point-slope formula: y - y = m(x - x)

Plug in the slope and point

y - (-5) = -3(x - (-2))

Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.

y + 5 = -3x - 6

Subtract the 5 from both sides

y = -3x - 11

The equation of the line is y = -3x - 11

Given the dimension

Length of the rectangle = 8cm

Width = 5cm

Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m

If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;

5 * 10 = 50m

Hence the width of the new stage will be 50 m

Step-by-step explanation:

Raia’s monthly car payments is $8160.

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that, Raia purchases a new car for $32,000 and finances it with a 6-year simple interest loan at a rate of 4.25%

We need to find;

What are Raia’s monthly car payments?

So, SI = PRT / 100

P = Principal amount

r = rate

T = time

So,

SI = 32000 x 4.25 x 6 / 100

= 8160

Hence, Raia’s monthly car payments is $8160.
