Write your answer using only positive exponets.
[tex]x {}^{n} .x {}^{m} = x {}^{n + m} [/tex]
Similarly:[tex]x { }^{ \frac{1}{2} } .x {}^{ \frac{ - 1}{6} } .x {}^{ \frac{ - 5}{2} } = x {}^{ \frac{1}{2} - \frac{1}{6} - \frac{5}{2} } [/tex]
We have to achieve a common denominator which is 6 here:[tex]x {}^{ \frac{3 - 1 - 15}{6} } =x {}^{ \frac{ - 13}{6} } [/tex]
To change our exponent to positive:
[tex]x {}^{ \frac{ - 13}{6} } = \frac{1}{x {}^{ \frac{13}{6}}} = \frac{1}{ \sqrt[6]{x {}^{13} } } = \frac{1}{x \sqrt[6]{x} } [/tex]
A fireplace arch is to be constructed in the form of a semi ellipse. The opening is to have the height of 1 foot at the center and a width of 6 feet along the base. The contractor cuts a string of a certain length and nails each end of the string at the foci of the base in order to sketch the outline of the semi ellipse. What is the total length of the string?
Answer:
6 feet.
Step-by-step explanation:
Remember that the foci of the semi-ellipse are two points in the base of the semi-ellipse from where you can create the full perimeter of the semi-ellipse, basically form there you can sketch it. And the sum of both to the same spot in the perimeter always adds up to the same number.
To calculate it you just need to remember that the major axis is always equal to that rope that you use to draw the semi-ellipse and since the major axis is the same as the base the rope will be 6 feet.

Answer:
I think the altimeter read this position as 10.6 ft
hope it help you
Answer:
10.6
Step-by-step explanation:
An altimeter measures the altitude of an object above sea level.
And the picture shows that Jenalle's position is 10.6 ft above water.
So the altimeter would measure 10.6

Sophie drove to the amusement park at a rate of 36 mph and arrived in 2.5 hours. How long will it take her to get home if Sophie drives 45 mph?
Answer:
Time= 2 Hours
Step-by-step explanation:
Using the formula attached we can first work out the distance from home to the amusement park. and then calculate the time it will take to get amusement park to home.
a) Distance= Speed x Time
= 90km
b) Time= Distance/speed
= 2 hours
Answer: 2 hrs
Step-by-step explanation: 36x2=72
1/2 of 36 is 18
72+18=90.
90mph/45 miles to cover = 2 hours.

A sphere has a radius of 15 inches. What is the volume of the sphere, in cubic inches? (Use 3.14 as an approximation of pi.)
Based on the calculations, the volume of this sphere is equal to 14,130 cubic inches.
Given the following data:
Radius of sphere = 15 inches.
[tex]\pi =3.14[/tex]
How to calculate the volume of a sphere.Mathematically, the volume of a sphere is given by this formula:
[tex]V=\frac{4}{3} \pi r^3[/tex]
Where:
V is the volume.r is the radius.Substituting the given parameters into the formula, we have;
[tex]V=\frac{4}{3} \times 3.14 \times 15^3\\\\V=\frac{4}{3} \times 3.14 \times 3375\\\\V=\frac{42390}{3}[/tex]
V = 14,130 cubic inches.

Two lines have the same slope and y-intercept. Describe the graph of the system of equations representing the two lines.
Answer:
Parallel lines.
Step-by-step explanation:
If the two linear equations have the same slope (and the SAME y-intercept), the equations represent the same line. Since a line intersects with itself everywhere, there will be an infinite number of solutions (intersecting everywhere.)
If two equations have the same slope and the same y-intercept, then they are the same line and an infinite solution .
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We have three cases in terms of slope and intercept:
The system has precisely one solution if the slopes of the two lines differ (whether the lines have the same intercept or different intercepts).There exists an infinite number of solutions to the system if they share the same slope and intercept, making them the same line.If they are parallel and have different intercepts but the same slope, there is no solution.So, The identical numerical values used for x and y in the first solution will also work for the second because these lines have an infinite number of solutions.

Solve for x =2.4x + 3.4=15.4
Answer :
5Explanation :
[tex]\longrightarrow \qquad \sf{2.4x + 3.4=15.4}[/tex]
Subracting 3.4 from both sides we get :
[tex]{\longrightarrow \qquad \sf{2.4x + 3.4 - 3.4=15.4 - 3.4}}[/tex]

Dividing 2.4 from both sides we get :

Represent 3200 divided by 100 in three different ways and simplify.
The answer of 3200 divided by 100 by three different ways is 32.
What is simplification?
Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given division is, 3200 divided by 100.
Since we know that division can be represented in three different way that is,
a) Factoring
b) Long division
c) Synthetic division
So,
a) Factoring 3200 divided by 100 we get,
(2x2x2x2x2x2x2x5x5)/(2x2x5x5)
= 2x2x2x2x2
= 32
b) Long division 3200 divided by 100
32
100| 3200
- 300
200
- 200
000
So,Quotient is 32
remainder is 0.
c) Synthetic division 3200 divided by 100
Let x = 100
Therefore, 3200 = 32x
now to divide 32x/x syntehtic division is given as,
1 | 32
1
Hence 32x/x by synthetic division we get 32 R 0.
Therefore, the required answer is 32.
