Rounded to the nearest hundredth of an inch, the distance is 310.91 inches.
How would you define distance?How far apart or how far away items or locations are from one another is measured numerically as distance. A physical quantity, it is typically stated in terms of meters, kilometers, miles, or feet. Given that it simply has magnitude and no direction, distance is a scalar quantity.
Usually, a formula is used to determine the distance between two points. One example is the distance formula in Euclidean geometry, which includes computing the square root of the sum of the squares of the coordinate differences between the two points.
Distance can be measured in a variety of contexts, including physics, where it is used to describe an object's displacement through time, and geography, where it is used to define the separation between two points on the surface of the Earth. It is also frequently used in daily life when people go for walks or runs or when they drive from one area to another to calculate the distance they travel.
There are no holes in the first and last 2 inches of the metal strip, leaving 3410 inches (3414 - 2 - 2) as the remaining length.
We can divide the total remaining length by the number of gaps between the holes to determine the distance between the centers of two adjacent holes. The distance between the 12 holes is determined by the fact that there are 11 gaps between them.
distance = (total length - length of 2 end pieces) / (number of gaps)
distance = (3410 in.) / 11
distance ≈ 310.91 in.
Rounded to the nearest hundredth of an inch, the distance is 310.91 inches.

The measure of angle that is an exterior angle to B is 95°.
What are exterior angles?The angle created by any extended side of a triangle and its neighboring side is referred to as the external angle of a triangle. A triangle has three external angles. It should be noticed that every outside angle and corresponding interior angle constitute a linear pair. We are aware that a triangle's internal angle is created when its sides come together at its apex.
Given that,
The measure of angle 4 is 120°, and the measure of angle 2 is 35°.
Triangle A B C. Angle A is 2, angle B is 1, and angle C is 3. The exterior angle to angle B is 5, and the exterior angle to angle C is 4.
The sum of an interior and exterior angle is 180°,
∠4 + ∠3 = ∠1 + ∠5 = ∠2 + ∠6 = 180°
and ∠2+ ∠1 +∠3 = 180°
Also, ∠3 = 180 - ∠4
∠3 = 180 - 120 = 60°
Substitute the values,
∠2+ ∠1 +∠3 = 180°
35 + ∠1 + 60 = 180
∠1 = 180 - 95
∠1 = 85°
Now, ∠1 + ∠5 = 180
∠5 = 180 - 85
∠5 = 95°
Hence, the measure of angle that is an exterior angle to B is 95°.

What is the x-intercept of this equation? 3x + 5y = 9
To find the x-intercept of the equation 3x + 5y = 9, we set y = 0 and solve for x.When y = 0, the equation becomes 3x + 5(0) = 9, which simplifies to 3x = 9.Solving for x, we get x = 3.The x-intercept of the equation 3x + 5y = 9 is (3, 0).
What is x-intercept ?
An x-intercept is a point where a graph or a line crosses the x-axis. It is the value of the independent variable (x) when the dependent variable (y) is equal to zero. In other words, it is the point at which a function or equation intersects the x-axis, and its coordinates are of the form (x, 0). To find the x-intercept of a graph or equation, you can set y=0 and solve for x.
To find the x-intercept of the equation 3x + 5y = 9, we need to set y = 0 and solve for x.
So, we have:
3x + 5(0) = 9
3x = 9
x = 3
Therefore, the x-intercept of the equation 3x + 5y = 9 is (3,0), which means the point where the line intersects the x-axis is (3,0).
To verify, we can graph the equation and see that the point (3,0) is indeed on the x-axis.

Joel opened a
savings account and
deposited $3500 as
principal. The account
earns 7% interest,
compounded
semianually. What is the
balance after 48
months?
Answer:
Step-by-step explanation:
The balance of the savings account after 48 months can be calculated using the formula for compound interest:
A = P * (1 + r/n)^(nt)
where:
A is the balance after t years
P is the principal (initial amount)
r is the interest rate (as a decimal)
n is the number of times compounded per year
t is the number of years
Step-by-step, the calculation is as follows:
Convert the interest rate from a percentage to a decimal:
r = 7% = 0.07
Determine the number of times compounded per year:
n = 2 (compounded semi-annually)
Determine the number of years:
t = 48 months / 12 months/year = 4 years
Plug the values into the formula:
A = P * (1 + r/n)^(nt)
A = $3500 * (1 + 0.07/2)^(2 * 4)
Calculate the balance using the formula:
A = $3500 * (1.035)^8
A = $3500 * 1.306769
A = $4588.72
So, the balance in the savings account after 48 months is $4588.72.

Suppose an object moves along the y axis so that its location is yequalsf(x)equalsxsquaredplusx at time x (y is in meters, x is in seconds). Find (A) The average velocity (the average rate of change of y with respect to x) for x changing from 2 to 5. (B) The average velocity for x changing from 2 to 2+h. (C) The instantaneous velocity at xequals2 second. (A) The average velocity is 8 m/sec. (B) The average velocity is (nothing )m/sec. (C) The instantaneous velocity is 5 m/sec.
When x changes from 2 to 5, the average velocity (or average rate of change of y with respect to x) is 9.33 m/s. When x changes from 2 to 2 + h, the average velocity is 2 + hm/s.
How can the average velocity be determined?Average speed is determined by dividing the total distance you travelled by the total time, whereas average velocity is determined by dividing your displacement (a vector Throughout the entire period, position to your finish position).
(A) The following formula is used to get the average velocity when x changes from 2 to 5:
value of y at x = 2
= 2²+2 = 6 m
value of y at x = 5
= 5²+5 = 30 m
displacement equals 30 – 6 = 24 m.
Time is 5 - 2 = 3 seconds.
average velocity
= displacement /Time duration
= 24/3 = m/s
B) Value of y at x = 2 = 5 for x changing from x to x plus ie for minimal change in x.
Displacement during a little change in x will be 0 because the value of y will once again be 5.
C )
