Find m<1 (1 point each)

We will know 8 complete names after 2 days and 20 complete names after 8 days.

Here, we are given an exponential function: f(t)= c{1- [tex]e^{-kt}[/tex]}

where f(t) = number of tasks learned.

c = total number of tasks to be learned

k = rate of learning

t = time

Now, when we move to a new school, number of names we need to learn ⇒ c = 25

learning rate for new tasks = 20%

⇒ k = 0.2

and time = 2 days

⇒ t = 2

Substituting these values in the given function we get-

f(2) = 25{1- [tex]e^{-0.2 *2}[/tex]}

= 25{1- [tex]e^{-0.4}[/tex]} [tex]e^{-0.4}[/tex]

= 0.67

Thus, f(2) = 25( 1-0.67 )

f(2) = 25(0.33)

f(2) = 8.25

Thus, we will be able to learn 8 complete names in 2 days.

If t = 8f(8) = 25{1- [tex]e^{-0.2 * 8}[/tex]}

= 25{1- [tex]e^{-1.6}[/tex]}

= 25(1- 0.20)= 25(0.80)

= 20

Thus, we will be able to learn 20 complete names in 8 days.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Total = 800 seats

On Monday 2/5

So, seats= 800*2/5 = 1600/5

=320 seats

On Tuesday

seats = 800 * 4/5

Answer:

[tex]\textsf{a)} \quad g'(x)=2x-4[/tex]

[tex]\textsf{b)} \quad y=2x[/tex]

[tex]\textsf{c)} \quad x=5[/tex]

Step-by-step explanation:

Given function:

[tex]g(x) = x^2-4x+9[/tex]

Differentiate the given function with respect to x:

[tex]\begin{aligned}g(x) & = x^2-4x+9\\\implies g'(x) & = 2 \cdot x^{2-1}-1 \cdot 4x^{1-1}+0\\& = 2x^{1}-4x^{0}\\& = 2x-4(1)\\& = 2x-4 \end{aligned}[/tex]

The y-value of the function at x = 3:

[tex]\begin{aligned}\implies g(3) & = (3)^2-4(3)+9\\& = 9-12+9\\& = -3+9\\& = 6\end{aligned}[/tex]

Therefore: (3, 6).

To find the slope of the function at x = 3, substitute x = 3 into the differentiated function:

[tex]\begin{aligned}\implies g'(x) & = 2(3)-4\\& = 6-4\\& = 2\end{aligned}[/tex]

Therefore, the slope of the function at x = 3 is 2.

Substitute the found slope and point (3, 6) into the point-slope form of linear equation to find the equation of the tangent line of g(x) at x = 3:

[tex]\begin{aligned} y-y_1 & =m(x-x_1)\\\implies y-6 & = 2(x-3)\\y-6 & = 2-6\\y & = 2x-6+6\\y&=2x\end{aligned}[/tex]

To find the value of x for which the slope of the graph is equal to 6, set the differentiated function to 6 and solve for x:

[tex]\begin{aligned}g'(x) & = 6\\\implies 2x-4 & = 6\\2x & = 6+4\\2x & = 10\\x & = \dfrac{10}{2}\\x & = 5\end{aligned}[/tex]

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

Answer: because if you have a argument you have all.

Step-by-step explanation:

Answer:

y = -1/3x + 2

Step-by-step explanation:

The slope of a line that is perpendicular has an opposite inverse of the slope of the line given.

The slope of the line given is 3.  The opposite inverse is -1/3.

Use the slope (-1/3), the x(3) and the y(1) to find the y-intercept (b) and to write the equation of the line.

y =mx + b

1 = -1/3(3) + b

1 = -1 + b  Add 1 to both sides

2 = b

y = -1/3x + 2

The total required cost of downloading books and videos is $57.92

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are:

Cost of downloading a book = $5.99

Cost of downloading a video = $7.99

The number of books and videos downlaoded are

Books = 3

Videos = 5

So, the total cost of downloading books and videos is

Total cost = Cost of downloading a book * x + Cost of downloading a video *  y

This gives

Total cost = Cost of downloading a book * Books + Cost of downloading a video *  Videos.

This gives

Total cost = 5.99 * 3 + 7.99 * 5

Evaluate

Total cost = 57.92

So, the total cost of downloading books and videos is $57.92

Hence, the total required cost of downloading books and videos is $57.92

Step-by-step explanation:

You need to divide 42 from 294.

If you are filling traffic cones with sand to keep them from blowing over and the cone has a radius of 7 inches and a height of 28 inches, then 1436 cubic inches of sand can fit inside the cone.

The volume of the cone can be described as the measure of a 3-D space occupied by matter.

The volume of sand in cubic inches that can fit inside the traffic cone can be calculated by the formula,

v = πr²h / 3

As the radius of the cone = 7 inches

Height of the cone = 28 inches

v = π(7)²28 / 3

v = (π)(49)(28) / 3

v = (π)(1372) / 3

As π = 3.14

v = (3.14)(1372) / 3

v = 4308.08 / 3

v = 1436.02 ≈ 1436 cubic inches

Hence, 1436 cubic inches of sand is calculated to fit inside the cone.

Let [tex]n[/tex] be an integer such that

[tex]\begin{cases} n \equiv 1 \pmod 3 \\ n \equiv 3 \pmod 4 \\ n \equiv 1 \pmod 5 \end{cases}[/tex]

Note that (3, 4, 5) are mutually coprime, so we can use the Chinese remainder theorem.

Starting with

[tex]n = 1 + 3 + 1[/tex]

we adjust to

[tex]n = (1\cdot4\cdot5) + (3\cdot3\cdot5) + (1\cdot3\cdot4)[/tex]

to make computing the residues a bit easier.

• Taken modulo 3, we have

[tex]n \equiv 20 + 0 + 0 \equiv 2 \not\equiv 1 \pmod 3[/tex]

so we need to further adjust the first term by introducing the inverse of 2 modulo 3. We have

[tex]2\cdot2 \equiv 4 \equiv 1 \pmod 3 \implies 2^{-1} \equiv 2 \pmod 3[/tex]

Then

[tex]n = (1\cdot4\cdot5\cdot2) + (3\cdot3\cdot5) + (1\cdot3\cdot4)[/tex]

• Taken modulo 4, we have

[tex]n \equiv 0 + 45 + 0 \equiv 1 \not\equiv 3 \pmod 4[/tex]

We need another inverse; we have

[tex]3\cdot3 \equiv 9 \equiv 1 \pmod 4 \implies 3^{-1} \equiv 3 \pmod 4[/tex]

and so

[tex]n = (1\cdot4\cdot5\cdot2) + (3\cdot3\cdot5\cdot3) + (1\cdot3\cdot4)[/tex]

• Taken modulo 5, we have

[tex]n \equiv 0 + 0 + 12 \equiv 2 \not\equiv 1 \pmod 5[/tex]

One more inverse:

[tex]2\cdot3 \equiv 6 \equiv 1 \pmod 5 \implies 2^{-1} \equiv 3 \pmod 5[/tex]

and so

[tex]n = (1\cdot4\cdot5\cdot2) + (3\cdot3\cdot5\cdot3) + (1\cdot3\cdot4\cdot3)[/tex]

Simplifying, we have [tex]n = 211[/tex], and by the CRT we have

[tex]n \equiv 211 \pmod{3\cdot4\cdot5} \implies n \equiv 31 \pmod{60}[/tex]

which is to say [tex]n=60k + 31[/tex] where [tex]k[/tex] is an integer.

The two integers that fall between 1 and 100 occur for [tex]k\in\{0,1\}[/tex]; they are 31 and 31 + 60 = 91, and their sum is 31 + 91 = 122.

Answer:

∠ ABC = 52° , ∠ CBD = 38°

Step-by-step explanation:

the 2 angles form a right angle and sum to 90° , that is

∠ ABC + ∠ CBD = 90

4x + 4 + 5x - 22 = 90

9x - 18 = 90 ( add 18 to both sides )

9x = 108 ( divide both sides by 9 )

x = 12

then

∠ ABC = 4x + 4 = 4(12) + 4 = 48 + 4 = 52°

∠ CBD = 5x - 22 = 5(12) - 22 = 60 - 22 = 38°

5x-12-6x=-10x+7-1
