During low tide, the beachfront in some places is about 350 from the ocean to the homes . High tide can change the width of a beach at a rate of -17 feet each hour . It takes 6 hours for the ocean to move from low to high tide . What is the change in the width of the beachfront from low to high tide ?
the change in width would be -17 * 6 = -102 feet
distance from the ocean to the houses would be 350-102= 248 feet

HURRY IM BEING TIMED!!
Answer:
Step-by-step explanation:
Given: –x² + 2x + 3 = x² – 2x + 3 .
To find: What are the solution(s) .
Solution: we have given that
–x² + 2x + 3 = x² – 2x + 3 .
On subtracting both side by x² .
-2x² + 2x + 3 = x² - x² - 2x + 3
-2x² + 2x + 3 = -2x +3
On Addition both side by 2x .
-2x² + 2x + 2x + 3 =-2x +2x +3
-2x² + 4x + 3 = 3
On subtracting both side by -3 .
-2x² + 4x + 3 -3 = 3 - 3
-2x² + 4x = 0
Taking common 2x .
2x (- x +2 ) =0 .
On grouping .
2x= 0
so x= 0
Now , -x +2 =0 .
-x = -2 .
On dividing by -1
x= 2
Therefore , option B is 0 and 2 .

Which fraction has a value greater than 0.4
the distance around the tire or a motorized scooter is 21.98. the tires make one revolutioneer 1/10 second.Find the speed of the scooter in miles per hour.
for every 1/10 second it travels 21.98 inches
for a full second it travels 21.98 x 10 = 219.8 inches
for 1 minute it travels 219.8 x 60 = 2820 inches / 12 = 235 feet per minute
235*60 = 14100 feet per hour
5280 feet per mile
14100/5280 = 2.67 = 2.7 miles per hour
The speed of the scooter with a tire circumference of 21.98 inches rotating at 1/10 second per revolution is approximately 12.5 mph after converting the distance traveled in inches per second to miles per hour.
To calculate the speed of the scooter in miles per hour, we first need to determine how far the scooter travels in 1 second. Since the tires make one revolution every 1/10 of a second, and the distance around one tire is 21.98 inches, in one second the tire will cover a distance equal to 10 revolutions (because 1 second divided by 1/10 second per revolution equals 10 revolutions). Hence, the scooter travels 21.98 inches imes 10 revolutions = 219.8 inches per second.
To convert this speed to miles per hour, we'll first convert inches to miles (1 mile = 63,360 inches), then seconds to hours (1 hour = 3600 seconds).
Calculate Miles per Hour
Speed in miles per second = 219.8 inches/s imes (1 mile / 63360 inches) = 0.003468 miles per second.
Speed in miles per hour = 0.003468 miles/s imes 3600 s/h = 12.4848 mph.
Therefore, the speed of the scooter is approximately 12.5 mph.

In order to build a scale model of the trail, the drawing is enlarged on the coordinate plane. If two corners of the trail are at point A(−2, 7) and point D(−10, −1), what is another point that could represent a corner of the trail?
(10, 7)
(14, 7)
(12, 7)
(8, 7)
From the coordinate plane, we can see that the enlarged point A refers to point F, and enlarged point D refers to point I. To solve for this problem, we know that the ratios of each side should be similar (both the original and enlarged). Since the given choices have all y values equal to 7, so we have to look for the enlarged point of point G. Let us call that point as point C.
In this case, we take the ratio of side IF and side FG. First solving for length using distance formula:
IF^2 = (2 – 4)^2 + (-4 - -2)^2
IF^2 = 8
IF = sqrt 8
FG^2 = (7 – 4)^2 + (-2 - -2)^2
FG^2 = 9
FG = 3
Therefore the ratio of IF/FG must be equal to the ratio of DA / AC:
IF / FG = DA / AC
Find DA first:
DA^2 = (-10 - -2)^2 + (-1 -7)^2
DA^2 = 128
DA = sqrt 128
So,
sqrt 8 / 3 = sqrt 128 / AC
AC = 12
Finding for point C: y of point C = 7
AC^2 = (x - -2)^2 + (7 – 7)^2
12^2 = (x + 2)^2
x + 2 = 12
x = 10

Write a conjecture for the pattern of the sequence
To conjecture a sequence, one must identify and extend the observable pattern, much like the quark hypothesis predicted unseen particles, or like recognizing the vowel sounds in specific linguistic patterns.
Explanation:In mathematics, creating a conjecture for a sequence involves analyzing the given numbers or patterns and predicting the next element based on the identified pattern. The process comparable to what the developers of the quark hypothesis did, working to predict unknown elements based on established patterns, can aid us in formulating a conjecture for the sequence in question.
For instance, if we refer to the resonance frequencies of a closed tube which form a pattern represented by the formula An = L / (4n) where n is an odd number, we can conjecture that the next frequency in the sequence would be determined by the next odd integer following the last one used.
Similarly, the binomial theorem expansion shows a pattern of coefficients that can be used to conjecture future terms in a binomial expansion. Analyzing patterns like VCC and VCle that determine whether the vowel sound should be long or short in English offer a linguistic parallel to mathematical pattern predictions.
To create a conjecture for a sequence, examine the values and look for a consistent relationship or rule. An example is adding 3 to the previous term in the sequence.
Explanation:A conjecture for the pattern of a sequence can be created by examining the values in the sequence and looking for a consistent relationship or rule. For example, if the sequence is 1, 4, 7, 10, 13, the conjecture may be that each term is obtained by adding 3 to the previous term. This can be represented mathematically as An = A(n-1) + 3, where An represents the nth term in the sequence.

I got up to this:
(cos x - 1)/ (cos x(1 - cos x)
Can you help me verify the following identity?
We are given the trigonometric equation:
(1 - sec x) / (1 - cos x) = - sec x
Since the left side has more terms, then let us work on that side to make it exactly like the right side.
We know that sec = 1 / cos, therefore:
(1 – 1 / cos x) / (1 – cos x) = - sec x
[(cos x – 1) / cos x] / (1 – cos x) = - sec x
[- (1 – cos x) / cos x] / (1 – cos x) = - sec x
Cancelling out the term (1 – cos x):
- 1 / cos x = - sec x
- sec x = - sec x

C.) d = 54 + t
D.) t = 54 + d
you would multiply the number of hours (t) by the speed (54) to find the distance (d)
so A) d=54t

How fast was Matt driving if he drove 415 miles in 7 hours?
The speed of Matt nearest to tenth place will be 59.3 miles per hour.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Matt drove 415 miles in 7 hours. Then the speed of Matt is calculated as,
Speed = 415 / 7
Simplify the equation, then we have
Speed = 59.2857 miles per hour
Speed = 59.3 miles per hour
The speed of Matt closest to the 10th spot will be 59.3 miles each hour.
