Find the value for 4x if x = 5

Answer: [tex]x\geq0[/tex] or [tex][0,\infty)[/tex]

Step-by-step explanation:

You have the function:

[tex]y=\sqrt{x}[/tex]

The domain of the function is the set of all the possible input values that the function can has.

We know that the square root of a negative number is not defined in the Real numbers. Therefore, "x" cannot be a negative number.

Then the domain of f(x) will be:

[tex]x\geq0[/tex] or [tex][0,\infty)[/tex]

Answer:

Step-by-step explanation:

Can you write this as y = √x?

The domain of the function y = √x is [0, ∞ ).  In elementary algebra, before you encounter imaginary numbers, y = √x is not defined for negative x.

ANSWER

The points (1,2) and (7,2) lie on the given curve.

EXPLANATION

The given parametric equations are:

[tex]x = 3t + 4[/tex]

and

[tex]y = 2 {t}^{2} [/tex]

We make t the subject in the first equation to obtain:

[tex]t = \frac{x - 4}{3} [/tex]

We substitute this into the second equation to get:

[tex]y =2{(\frac{x - 4}{3} )}^{2} [/tex]

When x=1,

[tex]y = 2 {(\frac{1 - 4}{3} )}^{2} = 2[/tex]

When x=2

[tex]y =2{(\frac{2- 4}{3} )}^{2} = \frac{8}{9} [/tex]

When x=7,

[tex]y =2{(\frac{7 - 4}{3} )}^{2} = 2[/tex]

Therefore the points (1,2) and (7,2) lie on the given curve.

The points are on a plane curve described by the following set of parametric equations are:(1,2), (7,2).

Given:

x= 3t+4 and y= 2t²

Hence:

x=3t +4 = t=(x-4)/3

y=2t² =y=2[(x-4)/3]

y=2[(x-4)/3]²

When x=1

y=2(1-4/3)²

y=2(-3/3)²

y=2(1)

y=2

When x=7

y=2(7-4/3)²

y=2(3/3)²

y=2(1)

y=2

Therefore the points are on a plane curve described by the following set of parametric equations are:(1,2), (7,2).

Answer:

  B:  -34

Step-by-step explanation:

The given angles are supplementary, so you have ...

  (2x+146) + (4x+238) = 180

  6x +384 = 180 . . . . . simplify

  6x = -204 . . . . . . . . . subtract 384

  x = -34 . . . . . . . . . . . .divide by 6

_____

Check

angle F is (2·(-34)+146)° = 78°

angle C is (4·(-34)+238)° = 102°

These angles indeed are supplementary, so the answer checks OK.

X=-34; add both expressions together and solve for x

For this case we must rewrite the following expression:

[tex]x ^ {\frac {9} {7}}[/tex]

By definition of properties of powers and radicals we have to:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

Then, the expression can be rewritten as:

[tex]x ^ {\frac {9} {7}} = \sqrt [7] {x ^ 9}[/tex]

If we want to simplify:

[tex]\sqrt [7] {x ^ 9} = \sqrt [7] {x ^ 7 * x ^ 2} = x \sqrt [7] {x ^ 2}[/tex]

ANswer:

[tex]x ^ {\frac {9} {7}} = \sqrt [7] {x ^ 9} = x \sqrt [7] {x ^ 2}[/tex]

Answer:

Step-by-step explanation:

(7y)² = 7²×y² = 49y²

In order to simplify the expression (7y)^2, we need to apply the exponent to both the numerical coefficient and the variable inside the parentheses. Here's how to do it step-by-step:
1. The expression (7y)^2 denotes that everything inside the parentheses is to be squared. That means we multiply 7y by itself.
2. When squaring a product, we square each factor separately. So we have to square both the 7 and the y.
3. Squaring 7 gives us 7^2, which equals 49.
4. Squaring the variable y gives us y^2.
5. Now, we multiply 49 by y^2 to combine our results.
Putting these steps together, we see that (7y)^2 simplifies to 49y^2.
The final simplified expression without parentheses is 49y^2.

Answer:

The diameter of the circle is [tex]D=36\ in[/tex] and the radius is [tex]r=18\ in[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=\pi D[/tex]

where

D is the diameter of the circle

we have

[tex]C=113.04\ in[/tex]

substitute and solve for D

[tex]113.04=(3.14)D[/tex]

[tex]D=113.04/(3.14)[/tex]

[tex]D=36\ in[/tex]

Find the radius r

[tex]r=36/2=18\ in[/tex] -----> the radius is half the diameter

Answer:

  see below

Step-by-step explanation:

The images are mirrored right/left, so the reflection must be across the y-axis. That only leaves two answer choices.

If you translate ABC to the left, you will put it entirely in quadrant II, so reflection across the y-axis will put it in quadrant I. Obviously, that is not the correct sequence of transformations.

If you translate ABC 3 units to the right, it will put line AB on x=2. Then reflection across the y-axis will put that vertical segment on x = -2, exactly where corresponding segment DE is located.

The appropriate choice is the one shown below:

Final answer:

To calculate the commission, multiply the sale price of $8,800 by the commission rate of 5% to get a commission of $440.

Explanation:

The question is asking to calculate the commission a salesperson earns from selling a used car. The salesperson earns a 5% commission on the sale price of the car, which is $8,800. To find the commission, we multiply the sale price by the commission rate:

Sale Price = $8,800
Commission Rate = 5% (or 0.05 in decimal form)

Commission = Sale Price × Commission Rate
Commission = $8,800 × 0.05
Commission = $440

Therefore, the salesperson earns a commission of $440.

Answer:

z = [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Given z is directly proportional to x and inversely proportional to y then the equation relating them is

z = [tex]\frac{kx}{y}[/tex] ← k is the constant of proportionality

To find k use the condition x = 7, y = 7 and z = 2

k = [tex]\frac{zy}{x}[/tex] = [tex]\frac{2(7)}{7}[/tex] = 2

z = [tex]\frac{2x}{y}[/tex] ← equation of proportionality

When x = 10 and y = 12, then

z = [tex]\frac{2(10)}{12}[/tex] = [tex]\frac{20}{12}[/tex] = [tex]\frac{5}{3}[/tex]

Answer:

100.8°

Step-by-step explanation:

∠POR = ∠POQ + ∠QOR

∠POQ is 20% of 360° ( measure of the angles in a circle )

= 0.2 × 360° = 72°

∠QOR is 8% of 360° = 0.08 × 360° = 28.8°

Hence

arc PR = ∠POR = 72° + 28.8° = 100.8°

Final answer:

To find the total cost of a CD with a 20% discount and 8% sales tax, calculate the discount on the original price, subtract it to find the discounted price, then add the sales tax to this discounted price. The total cost comes out to $12.10.

Explanation:

Calculating the Total Cost of a CD Including Discount and Sales Tax

Firstly, to determine the sale price of the CD that usually sells for $14.00 with a 20% discount, we apply the discount percentage to the original price. We convert 20% to its decimal form, which is 0.20, and multiply by $14.00 to find the amount discounted: $14.00 × 0.20 = $2.80. Subtracting this discount from the original price, $14.00 - $2.80, gives us the discounted price of the CD, which is $11.20.

Next, to calculate the total cost including a sales tax of 8%, we first convert the tax rate to its decimal form, 0.08, and multiply it by the discounted price: $11.20 ×0.08 = $0.896. Rounding to the nearest cent, the sales tax is approximately $0.90. Adding the sales tax to the discounted price, $11.20 + $0.90, gives us the total cost of the CD, which is $12.10.

Therefore, the total price of the CD, including the 20% discount and the 8% sales tax, is $12.10.

Answer:

8

Step-by-step explanation:

We want to evaluate the function f(x) = 3(log to the base 2 of x) + (log to the base 2 of 1/x) at x = 16.

Note that 2^4 = 16, so (log to the base 2 of 16) is 4.

Also note that 1/16 = 1/(2^4), so (log to the base 2 of 1/(2^4 is -4.

In summary, f(x) = 3(log to the base 2 of x) + (log to the base 2 of 1/x) at x = 16 is equal to 3(4) -4, or 8.

Answer:

  C)  f(x) = tan^-1(x)

Step-by-step explanation:

The question is equivalent to asking which trig function passes the horizontal line test over the domain (-90°, 90°). Both the sine function and the tangent function are defined on that domain and pass the horizontal line test.

The inverse sine function has a range of [-90°, 90°] (with square brackets, signifying the end points are part of the range). The inverse tangent function does not have a range that includes ±90°, so is a better match for the range in the question.

Answer:

∠H= 109º

∠F = 71º

∠G = 109º

Step-by-step explanation:

∠I = 71º

Interior opposite angles of parallel lines sums up to 180º.

∠H = 180 - 71 = 109º

Line IH is equal to Line FG.

∠F = ∠I

∠F = 71º

∠G = ∠H

∠G = 109º

Option a

[tex]f(x) = e^{x-1} -2[/tex]

Step-by-step explanation:

If the graph of the function [tex]y=f(x+h) +b[/tex]  represents the transformations made to the graph of [tex]y= f(x)[/tex]  then, by definition:

If [tex]b> 0[/tex] the graph moves vertically upwards b units.

If [tex]b <0[/tex] the graph moves vertically down  b units

If [tex]h<0[/tex] The graph moves horizontally h units to the right

If [tex]h>0[/tex] The graph moves horizontally h units to the left

In this problem we have the parent  function [tex]y=e^x[/tex]

We know that the parent function is translated 1 unit rigth and 2 units down.

This is:

[tex]h<0 = -1\\\\b < 0 = -2[/tex]

Finally the transformation is:

[tex]y=f(x-1) -2[/tex]

[tex]f(x) = e^{x-1} -2[/tex]
