If a map shows the straight line distance between two cities as 3 1/2 centimeters and the map scale shows that 1 centimeteer equals 100 kilometers what would the actual distance be
Answer:
The actual distance between the two cities is 350 kilometers
Step-by-step explanation:
Information given to us to answer the question correctly:
Distance between two cities in the map = 3 1/2 centimeters
Scale of the map: 1 centimeter = 100 kilometers
2. What would the actual distance be?
Let's calculate the actual distance between the two cities, this way:
Actual distance = Distance between two cities in the map * Scale of the map
Replacing with the real values:
Actual distance = 3.5 * 100
Actual distance = 350 kilometers

Claudia is on a motorcycle trip. She checked the odometer at the beginning of the trip, and it showed 16,789 miles. After 15 days it showed 22,189 miles. If Claudia rode the same number of miles each day how many miles did she ride in a day?
A.360 miles
B 540 miles.
C.771 miles
D.1,479 miles
please help me
22,189 - 16,789 = 5,400
5,400 / 15 = 360
360 miles a day
for the function f(x)= -(x + 1)^2 + 4 identify the vertex, domain, and range
Answer:
Vertex = (-1, 4)
Domain = All real numbers i.e. R
Range = (-∞, 4)
Step-by-step explanation:
The vertex of the quadratic equation:
f(x) = a(x - h)² + k
Here, Vertex = (h,k)
Thus, Vertex = (-1, 4)
Domain = All real numbers i.e. R
Range = All real numbers less than or equal to 4 i.e. (-∞, 4) or f = ≤ 4.
Further, the possible values of x are called Domain.
And, the possible output we get as y is called Range.
Which of the following best describes the following set of numbers? 6 + 8 + 10 + 12 + ... + (4 + 2n) + ...
answers:
Arithmetic SequenceGeometric SeriesGeometric SequenceArithmetic Series
Answer:
The term that best describes the given set of numbers is:
Arithmetic Series.
Step-by-step explanation:
We are given a series of numbers as:
6 + 8 + 10 + 12 + ... + (4 + 2n) + ...
Clearly as wee could see that each term in the given expression is separated by a plus sign, Hence, the given expression is a series and not a sequence.
Also as we could see that each in the series is more than the preceding term by 2 i.e. the common difference of the term is 2.
( Since, the set of numbers is given as:
[tex]a_0+a_1+a_2+a_3+....[/tex]
where,
[tex]a_n=2n+4[/tex]
[tex]when,n=0\\\\a_1=4\\\\when,n=1\\\\a_1=6\\\\and\ so\ on[/tex]
Also,
[tex]a_0-a_1=2\\\\Simialrly\\a_2-a_1=2\\\\and\ so\ on[/tex]
Hence, the common difference is 2. )
Hence, the given series is an Arithmetic series.

Gio is studying the rectangular pyramid below.
He believes the surface area, in square millimeters, can be found by simplifying this expression.
(4.2)(9.6)+1/2(4.2)(6.5)+1/2(9.6)(4.8)
What error is Gio making?
He used the wrong values as the bases of the lateral faces.
He used the wrong expression to represent the area of the base of the pyramid.
He used two different values as the heights of the lateral faces. NOT C
He used an expression for surface area that did not include all the faces.
PLZZ HELP
the answer is A. hope this helps!!!!
The error that Gio is making in finding the surface area of the rectangular pyramid is that He used an expression for surface area that did not include all the faces.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Given a rectangular pyramid.
Pyramid consists of one rectangular side and 4 triangular faces of which each pair of triangular faces is identical.
Total surface area of the pyramid is the total surface area of each faces.
Area of rectangular face = (4.2) (9.6)
Area of the triangular faces = [2 × 1/2 × 4.2 × 6.5] + [2 × 1/2 × 9.6 × 4.8]
= (4.2) (6.5) + (9.6) (4.8)
Total area = (4.2) (9.6) + (4.2) (6.5) + (9.6) (4.8)
So his mistake is that he only find the areas of two triangular faces.
Hence the correct option is that He used an expression for surface area that did not include all the faces.

What is the domain of the function
Answer:
The domain of the function is x>=-7
Step-by-step explanation:
The domain is all the values that x can take so the function is defined, that means we can find a value of y
The sqrt is defined only for positive values and zero. So the expression in the sqrt must satisfy that
6x + 42 >=0
We only have to find x
6x >=-42
x>=-42/6
x>=-7
So the answer is D x>=-7
