The size of a population of fish in a pond is modeled by the function P, where P(t) gives the number of fish and t gives the number of years after the first year of introduction of the fish to the pond for 0≤t≤10. The graph of the function P and the line tangent to P at t=4 are shown above. Which of the following gives the best estimate for the instantaneous rate of change of P at t=4 ?
Answers
The slope (m) will be "279.33". A further solution to the question is provided below.
At one moment this same instantaneous modification rate would be the same with the functionality derivative assessed somewhere at the time. In certain other terms, the pitch of such tangent line towards the curvature is somewhere at a level equivalent to that as well.
According to the question,
(x₁, y₁) = (3, 0)(x₂, y₂) = (6, 838)As we know,
⇒ [tex]Slope (m) = \frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
⇒ [tex]=\frac{838-0}{6-3}[/tex]
⇒ [tex]=\frac{838}{3}[/tex]
⇒ [tex]=279.33[/tex]

The instantaneous rate of change is the rate of change at a particular point or instant in the graph. The instantaneous rate of change of P at [tex]t=4[/tex] is 250
I've added as an attachment, the graph that represents the population of the fish.
To determine the instantaneous rate of change at [tex]t=4[/tex], we simply calculate the slope (m) of the tangent line using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Because of the scale of the graph, I will use the following estimated points from the tangent line
[tex](x_1,y_1) = (3,0)[/tex]
[tex](x_2,y_2) = (4,250)[/tex]
So, the slope is:
[tex]m = \frac{250 - 0}{4 - 3}[/tex]
[tex]m = \frac{250}{1}[/tex]
[tex]m = 250[/tex]
Hence, the instantaneous rate of change of P at [tex]t=4[/tex] is 250

Amaya wants to jog 8 Miles this week she has jog 2 1/2 miles on Monday and 3 2/5 miles on Wednesday how many miles does amaya still need to jog to meet her goal
Answers
Answer:
2 1/10 miles.
Step-by-step explanation:
She has already jogged 2 1/2 + 3 2/5 miles. This is 2 5/10 + 3 4/10 or 5 9/10. 8 miles is also equal to 7 10/10 miles. So, to find the remaining amount of miles, we can do 7 10/10 - 5 9/10 = 2 1/10.
Amaya still needs 2.1 miles to jog to meet her goal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
Operators who let do basic mathematical calculations.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
Given that this week she has jog 2 1/2 miles on Monday and 3 2/5 miles on Wednesday
She has already jogged 2 1/2 + 3 2/5 miles.
⇒ [tex]2\dfrac{1}{2} + 3\dfrac{2}{5} = \dfrac{5}{2} + \dfrac{17}{5}[/tex]
Convert fractions into decimals,
⇒ 2.5+3.4
Apply the arithmetic operation,
⇒ 5.9
So, to find the remaining amount of miles,
⇒ 8 -5.9 = 2.1
Hence, Amaya still needs 2.1 miles to jog to meet her goal.

[tex] \sqrt{ \frac{45}{5} } [/tex]
Answers
Answer: 3
Step-by-step explanation:
[tex]\sqrt{ \dfrac{45}{5}} =\sqrt{9}=\bold3[/tex]
Answer:
3
Step-by-step explanation:
We don't really need to simplify this, but if you do:
45/5 is the same as 45 ÷ 5 so
45/5 = 9
Now we have to find the square root of 45/5(or 9). The square root of a number(x for example) is the number(y) that multiplied by itself once will equal x or y · y = x.
For this you can use a calculator:
[tex]\sqrt{\frac{45}{5} }[/tex] = 3
or
[tex]\sqrt{9}[/tex] = 3
Refer to the number line. Find the coordinate of point H that is 1/5 of the distance from C to F.
A B C
DEF
-7-6-5-4-3-2-1 0 1 2 3 4 5 6 7
Answers
Number lines are used to represent numbers on a line at regular intervals. The coordinate of point H is -2.2
From the number line, we have:
[tex]C = -4[/tex]
[tex]F = 5[/tex]
First, we calculate the distance between C and F using absolute functions
[tex]CF = |C - F|[/tex]
[tex]CF = |-4- 5|[/tex]
[tex]CF = |-9|[/tex]
Remove absolute bracket
[tex]CF = 9[/tex]
Point H is [tex]\frac 15[/tex] of the distance so, we have:
[tex]H = \frac 15 CF[/tex]
[tex]H = \frac 15 \times 9[/tex]
[tex]H = 1.8[/tex]
This means that point H is 1.8 from the right of C.
So, the coordinate of H is:
[tex]H = C + 1.8[/tex]
[tex]H = -4 + 1.8[/tex]
[tex]H = -2.2[/tex]
Hence, the coordinate of point H is -2.2

what is six over seven times two and three over fourteen?
Answers
and seven is equal to six times a number.
Word problems can be tricky no matter what level of math or science you are in.
First look at the question for words that indicate mathematical symbols.
"times" indicates multiplication
"and" indicates addition
"a number" means we have a variable, x, to solve for
Now we can go from left to right and write it in a mathematical equation
7x + 7 = 6x
Then, solve for x
7x + 7 = 6x
7 = 6x - 7x
7 = -1x
7/-1 = x
x = -7
Finally, we check our work.
7x + 7 = 6x
7(-7) + 7 = 6(-7)
-49 + 7 = -42
-42 = -42 √
The answer is x = -7

n the number
7n 7 times the number
7n + 7 7 times the number and 7
Then the problem says it is equal 6n , make the equation
7n + 7 = 6n
and solve:
7n - 6n = -7
n = -7 / is the answer

Seven times a number and seven is equal to six times a number.
Step 1: Translate the verbal to Algebra.
7x + 7 = 6x. ("And" means addition if no other operation is present.)
Step 2: Solve for x.
7x - 6x + 7 = 6x - 6x. (subtract 6x from both sides)
1x + 7 = 0. (Simplify)
1x + 7 - 7 = 0 - 7. (subtract 7 from both sides)
1x = -7. (Simplify)
1x/1 = -7/1. (Divide both sides by 1)
x = -7. (Simplify)
Step 3: Check 7 times the number -7 and 7 is equal to six times the number -7.
7(-7) + 7 = 6(-7)
-49 + 7 = -42
-42 = -42. (Both sides are equal!)
The number again is -7.

Let's subtract 7x from both sides...
7x+7-7x=6x-7x
7=-x
Let's multiply both sides by -1...
(-1)(7)=(-1)(-x)
-7=x
Let's check our work...
7x+7=6x
[(7)(-7)]+7=(6)(-7)
-49+7=-42
