Answer: [tex]24\sqrt{3}[/tex]

Step-by-step explanation:

You need to remember that [tex]\sqrt[n]{a}[/tex] can be written in the following for:

[tex]a^{\frac{1}{n}}[/tex]

Knowing this and given the expression [tex](2*6)^{\frac{3}{2}}[/tex], you need to  multiply the numbers inside the parentheses:

 [tex](12)^{\frac{3}{2}}[/tex]

Rewrite it in this form:

[tex]=\sqrt{12^3}==\sqrt{1,728}[/tex]

Descompose 1,728 into its prime factors:

[tex]1,728=2*2*2*2*2*2*3*3*3=2^6*3^3[/tex]

Applying the Product of power property, which states that:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

You can say that:

 [tex]=\sqrt{1,728}=\sqrt{2^6*3^2*3}[/tex]

Simplifying, you get:

[tex]=2^3*3\sqrt{3}=24\sqrt{3}[/tex]

Answer:

Domain: All the real numbers

Range: All the real numbers

Step-by-step explanation:

The domain of a function is the complete set of possible values of the independent variable 'x'. That is to say, all the values that 'x' can take:

In this case, f(x)= 2x+1, the independent variable has no restrictions. Meaning that 'x' can take all the Real Values. In set notation: x∈ℝ.

The range of a function is the complete set of all possible resulting values of the dependent variable 'y'. In this case, given that the independent variable has no restrictions, the dependent variable 'y' can take any value. So, the range is: y ∈ ( −∞, ∞ ) - All the real numbers.

d = rt ( d = distance, r = rate (speed) and t = time)

14  = 7t

Divide both sides by 7:

t = 14/7

t = 2 hours

1 hour = 60 minutes.

2 hours x 60 = 120 minutes total.

Based on the distance Andrew went and the rate at which he went, Andrew's time in minutes was 120 minutes.

The distance formula is:

Distance = Rate x Time

Andrew's time is therefore:

14 = 7 x Time

Time = 14 / 7

= 2 hours

In minutes this is:

= 2 x 60 minutes per hour

= 120 minutes

In conclusion, Andrew covered that distance in 120 minutes.

~Just a girl in love with Shawn Mendes

Answer:

m = -1

Step-by-step explanation:

The slope is also called the gradient, m.

m=(y2-y1)/(x2-x1)

x1 = 0

y1 = 3

x2 = -4

y2 = 1

we therefore substitute for the values in the formula

m = (1-⁻3)/(⁻4-0)

m = -1

Answer: [tex]y=-\frac{5}{2}x-1[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

Write the equation of the given line in Slope-Intercept form by solving for "y":

[tex]5x + 2y = 12\\\\2y=-5x+12\\\\y=-\frac{5}{2}x+6[/tex]

You can observe that the slope of this line is:

[tex]m=-\frac{5}{2}[/tex]

Since the slopes of parallel lines are equal, then the slope of the other line is:

 [tex]m=-\frac{5}{2}[/tex]

Now, substitute the slope and the point (-2, 4) into  [tex]y=mx+b[/tex] and solve for "b":

[tex]4=-\frac{5}{2}(-2)+b\\\\4=\frac{10}{2}+b\\\\4-5=b\\\\b=-1[/tex]

Then the equation of the line parallel to the given line is:

[tex]y=-\frac{5}{2}x-1[/tex]

For this case we must indicate an expression equivalent to:

[tex]\sqrt {\frac {2x ^ 5} {18}}[/tex]

We rewrite 18 as 2 * 9:

[tex]\sqrt {\frac {2x ^ 5} {2 * 9}} =[/tex]

We simplify common factors:

[tex]\sqrt {\frac {x ^ 5} {9}} =[/tex]

We rewrite:

[tex]x ^ 5 = x ^ 4 * x = (x ^ 2) ^ 2 * x\\9 = 3 ^ 2[/tex]

So, we have:

[tex]\sqrt {\frac {(x ^ 2) ^ 2 * x} {3 ^ 2}} =\\\sqrt {(\frac {x ^ 2} {3}) ^ 2 * x} =[/tex]

Answer:

Step-by-step explanation:

this the gemetric  sequence  because : -12/6 =24/-12=-48/24=-2 (common rat)

the sum is : S=  u1 ×(d^n - 1)(d-1)

d = -2     u1  = 6     S= -2046

6((-2)^n -1) /(-2 -1) = -2046

(-2)^n -1  =1023

(-2)^n = 1024      but 1024 = 2^10 = (-2)^10

so : (-2)^n = (-2)^10

n=10  conclusion : 10 terms

The number of terms of the sequence is 10.

A geometric sequence exists a sequence of numbers where each term after the first term exists found by multiplying the earlier one by a fixed non-zero number, named the common ratio.

The terms of the sequence 6, -12, 24, -48, ...

Sum = -2046

Geometric sequence:

-12/6 = 24/-12 = -48/24 = -2

Sum of terms:

[tex]$S = u_{1} *(d^n - 1)(d-1)[/tex]

Let, d = -2, [tex]u_{1} = 6[/tex] and S = -2046

[tex]6((-2)^n -1) /(-2 -1) = -2046[/tex]

[tex](-2)^n -1 =1023[/tex]

[tex](-2)^n = 1024[/tex]

But the number of terms = 10

[tex]1024 = 2^{10} = (-2)^{10}[/tex]

so,[tex](-2)^{n} = (-2)^{10}[/tex]

4^(x- 3) = 18

ln[4^(x- 3)] = ln(18)

ln4(x - 3) = ln(18)

ln4x - ln4(3) = ln18

ln4x = ln18 + 3ln4

x = [ln18 + 3ln4]/ln4

x = 5.0849625007

x is approximately 5.085.

To solve the equation 4^x - 3 = 18, isolate the exponential term, take the logarithm of both sides, apply the power rule, and then divide to solve for x. The solution to the nearest thousandth is x ≈ 2.416.

To solve the equation 4^x - 3 = 18, first add 3 to both sides of the equation to isolate the exponential term:

4^x = 18 + 3

4^x = 21

Now, take the logarithm of both sides. You can use any logarithm base, but it's most common to use either the natural logarithm (ln) or the common logarithm (log base 10). For this example, we'll use the common logarithm.

log(4^x) = log(21)

Using the power rule for logarithms, which states that log(a^b) = b * log(a), you can write:

x * log(4) = log(21)

Now, divide both sides by log(4) to solve for x:

x = log(21) / log(4)

Use a calculator to find the value of x. Be sure to round your answer to the nearest thousandth, as the problem instructs. The answer comes out to:

x ≈ 2.416

This value of x solves the original equation when rounded to the nearest thousandth.

Answer:

Treat the lesser than sign as an equal sign. What you do to one side, you do to the other. Isolate the variable x. Do the opposite of PEMDAS.

PEMDAS = Parenthesis, Exponents ( & roots), Multiplication, Division, Addition, Subtraction.

Solve -6x + 14 < -28

First, subtract 14 from both sides:

-6x + 14 (-14) < -28 (-14)

-6x < -42

Next, divide -6 from both sides to isolate the variable x. Note that when you divide (or multiply) by a negative number, you must flip the greater than or less than sign.

(-6x)/-6 < (-42)/-6

x > (-42)/(-6)

x > 7

x > 7 is your answer.

Solve 3x + 28 < 25

First, subtract 28 from both sides.

3x + 28 (-28) < 25 (-28)

3x < -3

Isolate the variable x. Divide 3 from both sides. Note that because you aren't dividing by a negative number (rather a positive 3), you do not flip the sign.

(3x)/3 < (-3)/3

x < (-3)/(3)

x < -1

x < -1 is your answer.

Answer:

The correct option is 4. The value of f(-2) is 23.

Step-by-step explanation:

The given function is

[tex]f(x)=3x^2-2x+7[/tex]

We have to find the value of f(-2). It means we need to find the value of function f(x) at x=-2.

Substitute x=-2 in the given function to find the value of f(-2).

[tex]f(-2)=3(-2)^2-2(-2)+7[/tex]

On simplification we get

[tex]f(-2)=3(4)-(-4)+7[/tex]

[tex]f(-2)=12+4+7[/tex]

Second option: One solution. Independent.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

Since the equations of the system have this form, we know that they are lines.

We can identify that the y-intercept of the first equation [tex]y=-5x+1[/tex] is:

[tex]b=1[/tex]

Now we need to find the x-intercept. Substitute [tex]y=0[/tex] and solve for "x":

[tex]0=-5x+1\\\\5x=1\\\\x=\frac{1}{5}=0.2[/tex]

Then, we can graph the first line which passess through the points (0,1) and (0.2,0). Observe the graph attached.

The y-intercept of the second equation [tex]y=-2x-2[/tex] is:

[tex]b=-2[/tex]

Now we need to find the x-intercept. Substitute [tex]y=0[/tex] and solve for "x":

[tex]0=-2x-2\\\\2x=-2\\\\x=\frac{-2}{2}=-1[/tex]

Then, we can graph the second line, which passess through the points (0,-2) and (-1,0).

You can observe in the graph that the lines intersect at the point (1,-4). Therefore, that point is the solution of the system of equations.

Since the lines intersect, then there is one solution that is true for both equations. It is independent

The second set of brackets is a little bit tricker. Minus signs are not to be ignored.

Now put both together,

2r^2(2r + 5) - 5(2r + 5)            

Notice that there is a common factor on either side of that isolated minus sign. The common factor is 2r + 5. Use the distributive property to pull it out.

The solution to the system of equations given by the ordered pairs (7x+3y,2x+3y) and (24, 0) is x= -4.8 and y=3.2.

To solve for x and y, you need to equate each component of the ordered pairs and solve the resulting equations. In this case, you have:

Solving the second equation for x: x = -1.5y

Substitute x into the first equation: 7(-1.5y) + 3y = 24, which becomes -10.5y + 3y = 24, then -7.5y = 24

Solving for y, you get: y = -24 / -7.5 which equals y = 3.2.

Substituting y into the second equation 2x + 3(3.2) = 0, we get 2x = -9.6, so x = -9.6 / 2, so x = -4.8.

So, the values of x and y are -4.8 and 3.2 respectively.

Answer:

A

Step-by-step explanation:

Hihi. So, this is a nice application of interest rates as well as properties of exponentials/logarithms. As you know, the basic equation for interest rates is A= Pe^(rt) where A is your final amount, P is your initial, r is your rate of interest, and t is the time the money was accumulating interest. After cleaning up, you get in a situation due to you having e still lying around. Luckily, if you take the natural log of e, all you have left behind is the previous exponent. Thus, you can take the natural log of both sides, divide by 4, and then simplify to see that your final interest rate is ~6%

Answer:

A. 6%

Step-by-step explanation:

Since, the given amount formula is,

[tex]A=Pe^{rt}[/tex]

Where, P is the initial amount,

r is the periodic rate of interest,

t is the number of periods,

Here, P = $ 2000,

t = 4 years,

A = $ 2543,

By substituting the values,

[tex]2543=2000e^{4r}[/tex]

[tex]1.2715=e^{4r}[/tex]

Taking ln on both sides,

[tex]ln(1.2715)=4r[/tex]

[tex]\implies r = 0.06004932647\approx 0.06 = 6\%[/tex]

Hence, the rate of interest is 6 %.

Step-by-step explanation:

Given,

The original cost of the straw, P = $ 150.00,

The rate of decreasing per year, r = 1.5% = 0.015

Thus, the price after x years,

[tex]C(x)=P(1-r)^x[/tex]

[tex]\implies C(x) = 150(1-0.015)^x=150(0.985)^x[/tex]

Which is an exponential function,

∵ An exponential function [tex]f(x) = ab^x[/tex] has,

Decay : if 0 < b < 1,  ( decreasing from left to right )

Growth : if b > 1,  ( increasing from left to right )

Since, 0.985 < 1

Thus, the graph is decreasing from left to right,

if x = 2,

C(2) = [tex]150(0.985)^2[/tex] = 145.53375 ≠ 147.75,

I.e. (2, 147.75) does not lie on the graph,

If x = 3,

C(3) = [tex]150(0.985)^3[/tex] = 143.35 ≠ 141.20

i.e. (3, 141.20) does not lie on the graph.

Final answer:

The volume of the tilted solid is 1200 cubic feet.

Explanation:

The volume of the cube in the image is given as 1000 cubic feet. Let's call the height of the cube 'h'. The length and width of the cube are also 'h', so the volume of the cube is h x h x h = h³ = 1000. Solving for 'h', we find that h = 10 feet.

The tilted solid has the same base and height as the cube, but the length of each of its slanted sides is 2 units longer than the height. So the length of each slanted side is h + 2 = 10 + 2 = 12 feet.

To find the volume of the tilted solid, we can use the formula for the volume of a rectangular prism: volume = base area x height. The base area is h x h = h², and the height is 12 feet. Therefore, the volume of the tilted solid is h² x 12 = 10² x 12 = 1200 cubic feet.
