A dolphin dives from the surface into the ocean at a rate of 6.2 feet per second estimate the approximate location of the dolphin after 25 seconds
The approximate location of the dolphin is 155 feet as it moves at the rate of 6.2 feet per second.
Rate in defined as the speed or the distance travelled by the dolphin in unit time.
rate or speed is calculated by dividing the distance travelled by the total time taken to cover that distance.The units of rate is given by unit of distance/unit of time .The units of rate are meter/second , miles/hour , feet/second etc..Velocity is defined as the rate in a specified direction. Velocity is a vector quantity while speed or rate is a scalar quantity.Given the rate of the dolphin is feet per second .
Time taken by the dolphin is 25 seconds.
∴ distance travelled is given by rate × time
Hence distance travelled is 6.2 × 25 = 155 feet
Therefore the approximate location is given by 155 feet from the starting point.

Question Collapse ^ Given slope (gradient) of a line is 3 and two points that lie on that line are N(-2,3) and D(3, d). Find the value of d.
The value of d is 18.
Given, the slope of the line is 3.
Slope equals a height change (Change in width) You may also say that a slope is a climb or a run. This formula changes if the graph's horizontal axis is represented by x and the vertical axis by y: Slope is equal to (y-change)/ (Change in x)
Two points which lie are N(₋2 , 3) and D(3,d)
slope of the line = y₂ ₋ y₁/x₂ ₋ x₁
let the points N(₋2 , 3) be (x₁ , y₁)
and D(3,d) be (x₂ , y₂)
therefore, 3 = d ₋ 3/3 ₋ (₋2)
3 = d ₋ 3/3 ₊ 2
3 = d ₋ 3 / 5
15 = d ₋ 3
d = 15₊3
d = 18
Hence we get the value of d as 18.

Number between 50 and 80 that has exactly 4 factors one which is 2
58, 62 and 74 are the numbers between 50 and 80 that has exactly 4 factors with 2 being one of them 4.
As per the question statement, we are required to find out the numbers between 50 and 80 that has exactly 4 factors with 2 being one of the factors.
To solve this question, we need to know that every or any number in the number system as has at least 2 factors: 1 and the number itself.
Since we are to find numbers with exactly 4 factors, 2 being one of the factors and as per the above mentioned concept, two of the remaining three factors will be 1 and the number itself, the fourth factor has to be a prime number as prime numbers have no other factors than 1 and itself.
That is, we will have to find prime numbers (say "n") which when multiplied by 2 lies within the range of 50 and 80,
[tex]or, 50\leq (n*2) \leq 80\\or, \frac{50}{2}\leq n\leq \frac{80}{2}\\ or, 25\leq n\leq 40[/tex]
That is, we will need to find the prime numbers between 25 and 40; They are 29, 31 and 37.
Hence, our required numbers are [(29 * 2) = 58], [(31 * 2) = 62] and
[(37 * 2) = 74]. They lie between 50 and 80 that has exactly 4 factors with 2 being one of them.
Factors: In mathematics, a factor "x" of a number, say "y" is such a number that, "y" when divided by "x", the division leaves no remainder.Prime Numbers: Any number greater than 1, that has only two factors, 1 and the number itself is known as a prime number.To learn more about Factors, click on the link below.

The function f ( x ) = 2 x² + 5 will have the value 23 for f (- 3).
We are given the function:
f ( x ) = 2 x² + 5
We need to find the value of f ( -3 ).
We will do this by substituting the value of x = - 3 in the function and then evaluating the expression.
Putting x = -3 in the function, we get that:
f ( x = - 3 ) = 2 (- 3)² + 5
Solving the square, we get that:
f (- 3) = 2 ( 9 ) + 5
Simplifying the expression, we get that:
f (- 3) = 18 + 5
f (- 3) = 23

the perimeter P. of any rectangle is given by the formula P = 21 + 2w, where I represents the length if the rectangle and w represents the width. let the length of a rectangle equal 3 ft more than 3 times its width and the perimeter equal 54 ft
Answer:
width = 6 ft
length = 21 ft
Step-by-step explanation:
Forming algebraic expressions and finding the dimensions of a rectangle:
Width = w ft
length = 3*w + 3 = (3w + 3) ft
2l +2w = P
2(3w + 3) + 2w = 54
Use distributive property to open the brackets,
2*3w + 2*3 + 2w = 54
6w + 6 + 2w = 54
Combine like terms,
6w + 2w + 6 = 54
8w + 6 = 54
Subtract 6 from both sides,
8w = 54 - 6
8w = 48
Divide both sides by 8
w = 48 ÷ 8
[tex]\sf \boxed{\bf w = 6 \ ft}[/tex]
l = 3w + 3

An integer, pronounced "IN-tuh-jer," is a whole number that can be positive, negative, or zero and is not a fraction. Integer examples include: -5, 1, 5, 8, 97, and 3,043. 1.43, 1 3/4, 3.14, and other numbers that are not integers are some examples.Three categories of integers exist: Zero (0) Good integers (Natural numbers) Integer Negatives (Additive inverse of Natural Numbers)The first integer will be called x. Consequently, the second integer is x+1 and the third is x+2 (this is because they are consecutive integers). The total of these three numbers is 51, so build up the following equation and answer it.
x+(x+1)+(x+2)=51

The Z–Score, also known as the standard score, gives the number of standard deviations, a raw score is far from the mean.
