Which of the following represents ninth root of x to the seventh power in exponential form?

Answers

Answer 1

The exponent is 7/9 like this x^⁷⁄₉.

Answer 2

Answer:

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

Step-by-step explanation:

write ninth root of x to the seventh power in exponential form

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

To write the radical in exponential form we use the below property

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

The radical becomes the base of the fraction

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

we cannot simplify the fraction.

The given expression in exponential form is

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

Plug x = -2 into f(x) to get:
f(x) = 9*x + 7
f(-2) = 9*(-2) + 7
f(-2) = -18 + 7
f(-2) = -11

Do the same for g(x):
g(x) = 5^x
g(-2) = 5^(-2)
g(-2) = 0.04

----------------------------------------
Plug x = -1 into f(x) to get:
f(x) = 9*x + 7
f(-1) = 9*(-1) + 7
f(-1) = -9 + 7
f(-1) = -2

Do the same for g(x):
g(x) = 5^x
g(-1) = 5^(-1)
g(-1) = 0.2

----------------------------------------
Plug x = 0 into f(x) to get:
f(x) = 9*x + 7
f(0) = 9*(0) + 7
f(0) = 0 + 7
f(0) = 7

Do the same for g(x):
g(x) = 5^x
g(0) = 5^(0)
g(0) = 1

----------------------------------------
Plug x = 1 into f(x) to get:
f(x) = 9*x + 7
f(1) = 9*(1) + 7
f(1) = 9 + 7
f(1) = 16

Do the same for g(x):
g(x) = 5^x
g(1) = 5^(1)
g(1) = 5

----------------------------------------
Plug x = 2 into f(x) to get:
f(x) = 9*x + 7
f(2) = 9*(2) + 7
f(2) = 18 + 7
f(2) = 25

Do the same for g(x):
g(x) = 5^x
g(2) = 5^(2)
g(2) = 25

----------------------------------------

Write each of the results into the table (again see attached)

In the last row of that table, we have x = 2 lead to f(x) = 25 and g(x) = 25

So f(x) = g(x) has the solution of x = 2

The solution is x = 2 and not x = 25
25 is the output f(x) and g(x) value. It is not the x value.

Answer: choice C) x = 2

For a, since a straight line is 180 degrees, that means that x+x+35=180. Subtracting 35 from both sides, we get 145=2x. Next, we can divide both sides by 2 to get 72.5=x

For b, since vertical angles (opposite angles from intersecting lines) are equal, that means that 3x+13=5x-3. Subtracting 3x from both sides as well as adding 3, we get 2x=16. Dividing both sides by 2, we get x=8

Questions 1 & 2??????????

Answers

1) C. Paul and Sarah 2) D. I, III and IV For the first problem, let's look at the three proposed transformations and see which one(s) work. Mark. The points were reflected across the line y = x. Point A (-6,8) would translate to (8,-6) which is not correct. So Mark's idea is wrong. Paul, Reflect over the X-axis, then the Y-axis. Point A(-6,8) => (-6,-8) => (6,-8) Correct Point B(-2,2) => (-2,-2) => (2,-2) Correct Point C(-8,5) => (-8,-5) => (8,-5) Correct So Paul's translation works. Sarah, Rotate 180 degrees around (0,0) Point A(-6,8) => (6,-8) Correct Point B(-2,2) => (2,-2) Correct Point C(-8,5) => (8,-5) Correct So Sarah's translation works. So both Paul and Sarah have a translation that works.Looking at the available choices, the correct answer is C. Paul and Sarah The triangle OCD is given as congruent to the triangle JAL. That means that all the angles and lengths for each triangle matches the angle and length in the other triangle. Basically, both triangles are identical to each other. So let's see about the choices. I. is line segment OC congruent to line segment JA? Yes. OC is the first segment in the triangle OCD and JA is the first segment in triangle JAL. So they're congruent by definition. II. Is line segment OD congruent to line segment AL? No. Segment OD would be congruent to segment JL, or segment CD would be congruent to segment AL. III. Is angle COD congruent to angle AJL? Yes. COD is the angle around point O which is the 1st point in triangle OCD and AJL is the angle around point J which is also the 1st point in the triangle JAL. So they're congruent by definition. IV. Is the angle DCO congruent to angle JAL? C is the second point in triangle OCD and A is the second point in triangle JAL. The measure of the angle doesn't matter which way you're going. So they're congruent as well. So I, III, and IV are all true with II being false. Looking at the available choices, you see that "D. I, III and IV" is the correct answer.

bill is on the school archery team. the target has a center bull's-eye and two rings around the bull's-eye. the table gives the probabilities of each outcome. what is the probability that bill will get the next arrow in the inner or outer ring?express your answer as a decimal

Answers

add the 2 probabilities together:

0.297 + 0.423 = 0.72

Answer is C

Final answer:

To determine the probability that Bill will hit the inner or outer ring, you would subtract the probability of hitting the bull's-eye from 1, assuming there are no other sections on the target. If the probability of hitting the bull's-eye is 0.70, the combined probability for the inner or outer ring would be 0.30.

Explanation:

The question asks about the probability that Bill will hit either the inner or outer ring on an archery target, knowing that he hits the bull's-eye with certain probabilities. To find this probability, we need additional information that specifies the probabilities of hitting the inner and outer rings. Assuming we know the probabilities of all possible outcomes (inner ring, outer ring, and bull's-eye), we would add together the probabilities of hitting the inner and outer rings to get the total probability of hitting one of those two sections.

If hitting the bull's-eye has a probability of 0.70 (70%), and since the sum of all possible probabilities must equal 1 (100%), the combined probability of hitting either the inner or outer ring would be 1 - 0.70 = 0.30 or 30%. This assumes there are no other sections to hit on the target. The probability in decimal form would be 0.30.

He tax rates are as shown. nevada mining currently has taxable income of $97,800. how much additional tax will the firm owe if taxable income increases by $21,000?

Answers

Although there is a bit of information missing, I can answer this question in a general sense. If taxable income is $97,800, then the tax liability is $97,800 * (Tax Rate). For example, if the tax rate is %15 then the tax liability will be $97,800 * .15 = $14,670. If taxable income increases by $21,000, then the additional tax liability in addition to the $14,670 reported earlier will be $21,00 * .15 = $3,150. Please substitute whatever tax rate is given in the original problem wherever i stated .15 or %15. This is just an arbitrary number I used because the information was missing from the problem.

Answer:

4. Option 3rd.

Step-by-step explanation:

In this question, three options are given.

We need to describe the same situation.

First option: y = 3 + 6x

this equation represent the equation of a line. In that line all the points are related with each other with same relation.

So, this equation describe the same situation.

Second equation:

y is two more than six times x.

We write this situation in equation form.

y = 6x + 2

this is also describe the same situation.

Third option:

this table shows the x-y relation table.

Here no two points are describe the same situation.

A circle and a square have the same area. find the length of the diagonal of the square divided by the radius of the circle.

Answers

Let us say that the square have edge = sqrt(pi), then its area is pi since A = edge^2, and therefore the diagonal is pi*sqrt(2).

Meanwhile the circle of radius 1 has area pi since area of circle is A = pi *radius^2.

Therefore we get that the diagonal of the square divided by the radius is:

diagonal / radius = pi*sqrt(2) / 1 = pi*sqrt(2)

A dealer purchased a car for $29,700 and marked it up 12% what is the sticker price of the car

Answers

29,700•1.12=33,264 when adding % you just make it a decimal and add 1, if subtracting just make it negative

Answer: $ 33264

Step-by-step explanation:

Since, the original price of the car = $ 29,700

Marked up price = 12 % greater than the original price of the car

= Original price of the car + 12% of the original price of the car

= 29700 + 12% of 29700

= 29700 + 0.12 × 29700

= 29700 + 3564

= 33264

Hence, the marked price of the car = $ 33264

A shop makes $37.50 for selling 15 calendars. If the shop wants to make $2450, how many calendars does it need to sell?

Answers

First find the price per calendar.

37.50/15=$2.5 per calendar

Next find the amount of calendars by dividing the amount the shop wants to sell by the price per calendar.

2450/2.5=980 calendars

The shop needs to sell 980 calendars to make $2450.

To find out how many calendars the shop needs to sell to make $2450, we first determine the price per calendar by dividing the total amount made from selling a batch of calendars by the number of calendars in that batch. The shop makes $37.50 from selling 15 calendars, so each calendar is sold for $37.50 / 15 = $2.50. To reach the goal of $2450, we need to calculate the number of calendars by dividing the target amount by the price per calendar.

$2450 / $2.50 = 980 calendars

If EF=2x-5, FG=3x-6, and EG=19 find the values of x, EF, and FG. The drawing is not to scale.

a. x = 6, EF = 17, FG = 24
b. x = 1, EF = 7, FG = 12
c. x = 1, EF = -3, FG = -3
d. x = 6, EF = 7, FG = 12

Answers

EG is the whole thing.
This means that EF + FG = EG

EF=2x-5
FG=3x-6
EG=19

Now all you do is plug in the numbers.
(2x - 5) + (3x - 6) = 19
5x - 11 = 19
5x = 30
x = 6

Now plug that x into EF and FG.
EF = 2x - 5
EF = 2(6) - 5
EF = 12 - 5
EF = 7

FG = 3x - 6
FG = 3(6) - 6
FG = 18 - 6
FG = 12

So your answers are:
x = 6
EF = 7
FG = 12
d. x = 6, EF = 7, FG = 12
