The value of the exponent given as 2^18 times 2^9 is 2^27.
What is an exponent?The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.
In this case, 2^18 times 2^9 will be illustrated thus:
= 2^18 times 2^9
= 2^(18 + 9)
= 2^27
The value is 2^27.

using a similar argument to solve teh hw problem 1, show that if a is an integer, then 7 divides a^7 -a
The expression a⁷- a is divisible by 7 if a is an integer.
Given that,
7 divides a^7−a
To find that if a is an integer, then 7 divides a^7 -a or a⁷- a is divisible by the number 7
We can write, where k is an integer
a^7−a=7k
a(a^6−1)=7k
Now if a=k then
a^6−1=7
a^6=8
and a=±1.414 so a^7−a=9.898
If a is not equal to k then
a(a^6−1)=a(a^3+1)(a^3−1)=7k
since a(a+1)(a−1) is the not product of 3 consecutive integers, the expression is divisible by 7.
Hence, The expression a⁷- a is divisible by 7 if a is an integer.

Write the equation in standard form using integers
(no fractions or decimals): y= -2/3 x-1
The standard form of the equation y = -2/3 x - 1 is 2x + 3y = -3.
How to write linear equation in standard form?The standard form for linear equations in two variables is Ax + By = C. Where,
A, B and C are constant.x and y are the variables.The equation is represented in slope intercept form. So, let' represent it in standard form.
Therefore,
y = - 2 / 3 x - 1
add 2 / 3 x to both sides of the equation
y = - 2 / 3 x - 1
y + 2 / 3 x = - 2 / 3 x + 2 / 3 x - 1
y + 2 / 3 x = - 1
Let's multiply all through by 3 to eliminate the fraction
y + 2 / 3 x = - 1
3y + 3(2 / 3 x) = -3
Therefore, the standard form equation is 2x + 3y = -3

The inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).
From the question, we have
f(x) = ( 10/9x) + 11
x = ( 10 / 9y ) + 11
x - 11 = ( 10 / 9y )
9y / 10 = ( 1 / ( x - 11 )
9y = 10 / ( x - 11 )
y = ( 10 ) / ( 9x - 99 )

What number (let's call it x ) must be added to the numerator and denominator of the fraction 6/29 so that the new fraction is equal to 2/3 ?
Answer:
add 54 to the numerator and 61 to the denominator because after you add it the fraction, it should be 60/90: simplified to 2/3 if you divide the numerator and denominator by 30.
The number that must be added to the numerator and denominator is 40.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Fraction = 6/29
The new fraction = 2/3
Now,
(6 + x)/(29 + x) = 2/3
3(6 + x) = 2(29 + x)

A regulation baseball field measures 90 feet between each base what is the distance around the bases in yards
The distance around the bases in meters will be 27.432 meters.
How many meters are in 1 feet?
In one feet there are 0.3048 meters.
Given is a baseball field measures 90 feet between each base.
Distance between each base in feet = [d] = 90 feet
The distance between each base in meters will be -
D [meters] = 90 x 1 ft
D [meters] = 90 x 0.3048 meters
D [meters] = 27.432 meters
Therefore, the distance around the bases in meters will be 27.432 meters.

The image of the given point after the translation will be (-5,1).
The given point is (0,2).
We have to find out the image of the given point after a translation left 5 units and up to 1 units.
Since it is given that there is a translation left 5 units, starting from point (0,2), the image will be on the negative side of x-axis at point 3.
Similarly, it is given that there is also a translation up to 1 units. This implies starting from point (0,2), the image will be on the positive side of y-axis at point 1.

The side lengths of the fence he can build with the greatest area inside are of:
75 yards and 75 yards.
What are the area and the perimeter of a rectangle?Considering a rectangle of length l and width w, we have that the area and the perimeter of the rectangle are given as follows:
The area is given by the multiplication of the dimesions, that is, A = lw.The perimeter is given by twice the sum of the dimensions, that is, P = 2(l + w).A farmer has 300 yards of fencing, hence the perimeter is:
P = 300.
Then:
2(l + w) = 300
l + w = 150
l = 150 - w.
Then the equation giving the area of the fence is:
A = lw
A = w(150 - w)
A = -w² + 150w.
Which is a quadratic equation with coefficients given by:
a = -1, b = 150.
The width that will give the highest possible area is the x-coordinate of the vertex, hence:
w = -150/(2(-1)) = 75 yards.
The length is of:
l = 150 - w = 150 - 75 = 75 yards.
Which means that the third option is correct.

What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. △ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane. Equilateral, isosceles, scalene and right-angled triangles are the four different forms of triangles.So, the perimeter of the triangle is 392 cm.
The unequal side is 195.Then, let the rest 2 sides be x, where x = x.
x + x + 195 = 3922x + 195 = 3922x = 392 - 1952x = 197x = 197/2x = 98.5Now, we know that the rest 2 equal sides are of length 98.5 cm.

Step Two: Solve x +4y = 11 for x:
x +4y = 11
x +4y + −4y = 11 + −4y (Add -4y to both sides)
x = −4y +11
Step Three: Substitute −4y +11 for x in 3x +5y = 12:
3x +5y = 12
3(−4y +11) +5y = 12
−7y +33 = 12 (Simplify both sides of the equation)
−7y +33 +−33 = 12 +−33(Add -33 to both sides)
−7y = −21
(-7y/-7) = (-21/-7) (Divide both sides by -7)
y = 3

Sophia planted a tiny sunflower in her backyard at the start of spring.
When she planted the sunflower,

Now, The sunflower then began to grow at a rate of 3 inches per week.
Thus, the growth rate of the sunflower = 3 inches/week
The growth in 9 weeks = 3*9 = 27 inches,
The height of the sunflower after 9 weeks = initial height + growth = 25 +27 = 52 inches.
