I keep explaining that I have blank 1 as 9 and blank 2 as 5. Blank 1 is not correct. please help me solve

Answers

Answer 1

We have the following expression:

$3\sqrt[]{45}$

First, we must find the prime factorization of the number inside the radical:

$45=3\times3\times5$

Next, determine the index of the radical. In our case the index is two because it is a square root, which means we need two of a kind:

$45=3\times3\times5=3^2\times5$

Then, we can move 3 outside the radical, that is

$3\sqrt[]{45}=3\sqrt[]{3^2\times5}=3\times3\sqrt[]{5}$

and finally, simplify the expression both inside and outside the radical:

$3\sqrt[]{45}=9\sqrt[]{5}$

Then, the answer is

Answer:

Step-by-step explanation:

using the sine ratio in the right triangle on the left to find the vertical side , h, and the exact value

sin60° = $\frac{\sqrt{3} }{2}$ , then

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{h}{11}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2h = 11$\sqrt{3}$ ( divide both sides by 2 )

h = $\frac{11\sqrt{3} }{2}$

using the sine ratio in the right triangle on the right and the exact value

sin45° = $\frac{\sqrt{2} }{2}$ , then

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{h}{x}$ = $\frac{\frac{11\sqrt{3} }{2} }{x}$ = $\frac{\sqrt{2} }{2} }$ ( cross- multiply )

x = $\frac{11\sqrt{3} }{2}$ × $\frac{\sqrt{2} }{2}$ = $\frac{11\sqrt{3(2)} }{2(2)}$ = $\frac{11\sqrt{6} }{4}$

So then square root of 353 is 18.8

how many integers between 2023 and 5757 have 12, 20, and 28 as factors

Answers

Answer:

9 integers between 2023 and 5757 that have 12, 20, and 28 as factors.

Step-by-step explanation:

An integer that has 12, 20, and 28 as factors must be divisible by the least common multiple (LCM) of these numbers. The LCM of 12, 20, and 28 is 420. So we need to find the number of integers between 2023 and 5757 that are divisible by 420.

The first integer greater than or equal to 2023 that is divisible by 420 is 5 * 420 = 2100. The last integer less than or equal to 5757 that is divisible by 420 is 13 * 420 = 5460. So the integers between 2023 and 5757 that are divisible by 420 are 2100, 2520, ..., 5460. This is an arithmetic sequence with a common difference of 420.

The number of terms in this sequence can be found using the formula for the nth term of an arithmetic sequence: an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, d is the common difference, and n is the number of terms. Substituting the values for this sequence, we get:

5460 = 2100 + (n - 1)420 3360 = (n - 1)420 n - 1 = 8 n = 9

So there are 9 integers between 2023 and 5757 that have 12, 20, and 28 as factors.

a student spends 18 out of 35 of his pocket money on transport and fruit what is the fraction left?

Answers

To find the fraction of pocket money left after spending on transport and fruit, we need to subtract the amount spent from the total pocket money and express it as a fraction.

The student spends 18 out of 35 of his pocket money, which means he has (35 - 18) = 17 units of his pocket money left.

Therefore, the fraction of pocket money left can be written as 17/35.

17 units would be your answer

What method of differentiation is necessary, and what is the derivative?

Answers

The given function is

$f(x)=In\frac{2x^3}{\sqrt[]{x}}$

We need to use the derivation of some standard functions.

Recall that

$\frac{d}{dx}\text{In u(x)}=\frac{1}{x}u^{\prime}.$

Derivation of rational functions with quotient rule.

$\frac{d}{dx}(\frac{u(x)}{v(x)})=\frac{vu^{\prime}-uv^{\prime}}{v^2}$

Differentiate the given function with respect to x, we get

$f^{\prime}(x)=\frac{d}{dx}(In\frac{2x^3}{\sqrt[]{x}})$

$\text{Use }\frac{d}{dx}\text{In u(x)}=\frac{1}{x}u^{\prime}.$

$f^{\prime}(x)=\frac{1}{\frac{2x^3}{\sqrt[]{x}}}\frac{d}{dx}(\frac{2x^3}{\sqrt[]{x}})$

$f^{\prime}(x)=\frac{\sqrt[]{x}}{2x^3}\frac{d}{dx}(\frac{2x^3}{\sqrt[]{x}})$

$\text{Use }\frac{d}{dx}(\frac{u(x)}{v(x)})=\frac{vu^{\prime}-uv^{\prime}}{v^2}.$

$f^{\prime}(x)=\frac{\sqrt[]{x}}{2x^3}\times\frac{\sqrt[]{x}(2\times3x^2)-2x^3(\frac{1}{2}x^{-\frac{1}{2}})}{(\sqrt[]{x})^2}$

$f^{\prime}(x)=\frac{\sqrt[]{x}}{2x^3}\times\frac{6x^2\sqrt[]{x}-\frac{x^3}{\sqrt[]{x}}}{x}$

$f^{\prime}(x)=\frac{\sqrt[]{x}}{2x^3}\times\frac{\frac{6x^2\sqrt[]{x}\times\sqrt[]{x}}{\sqrt[]{x}}-\frac{x^3}{\sqrt[]{x}}}{x}$

$f^{\prime}(x)=\frac{\sqrt[]{x}}{2x^3}\times\frac{\frac{6x^3-x^3}{\sqrt[]{x}}}{x}$

$f^{\prime}(x)=\frac{\sqrt[]{x}}{2x^3}\times\frac{5x^3^{}}{\sqrt[]{x}}\times\frac{1}{x}$

$f^{\prime}(x)=\frac{5}{2x}$

Hence the required differentiation is

$f^{\prime}(x)=\frac{5}{2x}$

Answers

Answer:

v - u = 10t

t = 1/10x(v-u)

2. 1/6 x (m - 19) = n

3. u = d/t - at

4.- 1/6 x (A - P)

T = 2.5

Step-by-step explanation:

v = u + 10t

v- u = 10t

divide both sides of the equation by 10

t = 1/10x(v-u)

2. m = 6n + 19

subtract 19 from both sides of the equation

m - 19 = 6n

divide both sides of the equation by 6

1/6 x (m - 19) = n

3. d = ut + at²

subtract at² from both sides of the equation

d - at² = ut

divide both sides of the equation by t

(d/t) - at = u

4. P = A - 6D

subtract A from both sides of the equation

P - A = -6D

divide both sides of the equation by -6

-1/6(P - A) = D

Answers

Taking into account the definition of a system of linear equations, a student has 24 dimes and 6 nickels.

System of linear equations

A system of equations is a set of equations in which there are two or more variables, the goal of which is to find all ordered pairs (x, y) that satisfy the equation, where x and y are real numbers.

In other words, a system of linear equations is a set of two or more first degree equations that relate two or more unknowns, in which it is desired to find the value of each unknown so that all the equations of the system are satisfied.

This case

In this case, a system of linear equations must be proposed taking into account that:

d = number of dimes.n = number of nickels.

You know that:

A student has 30 dimes and nickels. The total value is $2.70.

The system of equations to be solved is

d + n = 30

0.10d + 0.05n = 2.70

It is decided to solve it using the substitution method. This method consists of isolate one of the variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable "d" from the first equation:

d= 30 -n

Replacing the expression in the second equation:

0.10×(30 - n) + 0.05n = 2.70

Solving:

0.10×30 - 0.10n + 0.05n = 2.70

3- 0.10n + 0.05n = 2.70

- 0.10n + 0.05n = 2.70 -3

-0.05n= -0.3

n= (-0.3)÷ (-0.05)

n= 6

Remembering that d=30 -n you get:

d= 30 - 6

d= 24

There are 24 dimes and 6 nickels.

What is a line plot?

In Mathematics and Statistics, a line plot refers a type of graph that is used to graphically represent a data set above a number line, while using crosses, dots, or any other mathematical symbol.

Based on the data and information provided in the line plot shown in the image attached above, we can calculate the total amount of sugar that was consumed by Kylie in the past nine (9) days as follows:

Total sugar consumed = (1/8 + 1/8 + 1/8) + 1/4 + (3/8 + 3/8 + 3/8) + (5/8 + 5/8)

Total sugar consumed = 3(1/8) + 1/4 + 3(3/8) + 2(5/8)

Total sugar consumed = 3/8 + 1/4 + 9/8 + 10/8

Total sugar consumed = 22/8 + 1/4

Total sugar consumed = (22 + 2)/8

Total sugar consumed = 24/8

Total sugar consumed = 3 units of sugar.

The derivative of this function is 2x/15. This is the slope of a tangent at that point.
If Linda lets go at some point along the parabola with coordinates (t, t^2 / 15), then she will travel along a line that was TANGENT to the parabola at that point.
Since that line has slope 2t/15, we can determine equation of line using point-slope formula:
y = m(x-x0) + y0
y = 2t/15 * (x - t) + (1/15)t^2
Plug in the x-coordinate "t" that was given for any point.

d)
We are looking for some x-coordinate "t" of a point on the parabola that holds the tangent line that passes through the dock at point (30, 30).
So, use our equation for a general tangent picked at point (t, t^2 / 15):
y = 2t/15 * (x - t) + (1/15)t^2
And plug in the condition that it must satisfy x=30, y=30.
30 = 2t/15 * (30 - t) + (1/15)t^2
t = 30 ± 2√15 = 8.79 or 51.21
The larger solution does in fact work for a tangent that passes through the dock, but it's not important for us because she would have to travel in reverse to get to the dock from that point.
So the only solution is she needs to let go x = 8.79 m east and y = 5.15 m north of the vertex.
