A rectangular city is 2 miles long and 7 miles wide. What is the distance between opposite corners of the city? The exact distance is ______________ miles How far is it to the closest tenth of a mile? Answer: The distance is approximately ___________ miles.
Answer:
√53 ≈ 7.3 miles
Step-by-step explanation:
The Pythagorean theorem can be used to find the length of a diagonal of a rectangle. The diagonal is effectively the hypotenuse of a right triangle with leg lengths equal to the side lengths of the rectangle.
__
If c represents the distance between opposite corners, and 'a' and 'b' represent the length and width of the city, then we have ...
c² = a² +b²
c² = 2² +7² = 53
c = √53 . . . . . exact corner-corner distance in miles
c ≈ 7.3 . . . . . . approximate corner-corner distance
The exact distance is √53 miles; to the nearest tenth, the distance is approximately 7.3 miles.

Answer:
3) D
5) C
3) 6m+5n-m --> 6(5)+5(3)-(5)
30+15-5 --> 45-5 --> 40
5) 4(x+4)+2
4x + 16 +2
4x +18
Answer:
3)
Given:
m = 5
n = 3
We plug in these values into our equation (6m + 5n - m);
6m + 5n - m
Now modified, would be:
6(5) + 5(3) - 5
30 + 15 - 5
45 - 5
= 40
5)
If we simplify this expression,
4(x + 4) + 2
We use the distributive property to multiply 4 to both x and 4 which are in the brackets.
Which will now be;
4x + 16 + 2
Now we combine like terms (our constants):
(16 + 2) = 18
So it would be, now:-
4x + 18, C is your answer.

Food poisoning occurs when bacteria like Salmonella and Listeria grow on food. These microorganisms grow at an
exponential rate. When an initial population of 100 bacteria are left at 98.6°F, they will grow at a rate of b= 100(8)". Which
graph could be used to calculate the number of bacteria after a certain number of hours?
The function that shows the number of bacteria after a certain number of hours is y = 100(8)ˣ
What is an exponential function?An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y represent the amount of bacteria after x hours. Hence:

Solution with Steps
1/7×2/3=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×2 and 7×3=2/21
This fraction cannot be reduced.
Therefore:
1/7×2/3=2/21
Solution by Formulas
Apply the fractions formula for multiplication, to
1/7×2/3
and solve
1×2 and 7×3
=2/21
Answer:
1/7 × 2/3 is 2/21
becuase, if you times the numerators, which are the top numbers; and then the denominators which are the bottom numbers; like if you multiply 1×2 you get 2 and 7×3 is 21.

A practice field is in the shape of a rectangle. The area of the practice field is represented by 5x^2 + 30x -7xy -42y. Find the expressions that represent the length and width of the practice field.
Answer:
length and width are x + 6 and 5x - 7y
Step-by-step explanation:
5x² + 30x - 7xy - 42y
= 5x(x + 6) - 7y(x + 6)
= (x + 6)(5x - 7y)
so
length and width are x + 6 and 5x - 7y

What is unitary method ?Unitary method is a mathematical way of first determining the value of a single unit then deriving the given unit from it.
According to the given question containers for international shipments measures 6 feet and 7 inches.
We know 1 feet is 12 inches.
∴ 6 feet is (12 × 6) = 72 inches.
So, 6 feet 7 inches is (72 + 7) inches which is 79 inches.
We know 1 inches is 0.0254 meter.
∴ 79 inches is ( 79 × 0.0254 ) meter which is

The graph of f ′ (x), the derivative of f(x), is continuous for all x and consists of five line segments as shown below. Given f (0) = 6, find the absolute maximum value of f (x) over the interval [0, 5].
2
8
11
13
The maxima of f(x) occur at its critical points, where f '(x) is zero or undefined. We're given f '(x) is continuous, so we only care about the first case. Looking at the plot, we see that f '(x) = 0 when x = -4, x = 0, and x = 5.
Notice that f '(x) ≥ 0 for all x in the interval [0, 5]. This means f(x) is strictly increasing, and so the absolute maximum of f(x) over [0, 5] occurs at x = 5.
By the fundamental theorem of calculus,
[tex]\displaystyle f(5) = f(0) + \int_0^5 f'(x) \, dx[/tex]
The definite integral corresponds to the area of a trapezoid with height 2 and "bases" of length 5 and 2, so
[tex]\displaystyle \int_0^5 f'(x) \, dx = \frac{5+2}2 \times 2 = 7[/tex]
[tex]\implies \max\{f(x) \mid 0\le x \le5\} = f(5) = f(0) + 7 = \boxed{13}[/tex]
