The distance between Franklin City and Williamsville on a map is 3.2 inches. If the scale of the map is 1 inch = 15 miles, how many miles apart are the two cities?
Answers
Answer: 48 miles
Step-by-step explanation:
From the question, the distance between Franklin City and Williamsville on a map is 3.2 inches and the scale of the map is 1 inch = 15 miles.
The distance between the cities will be to multiply 3.2 by 15 to get the number of miles since 1 inch = 15 miles. This will be:
= 3.2 × 15 miles.
= 48 miles
The distance between Franklin City and Williamsville is 48 miles.
Answer:
48 Miles

The equation x2 = d has how many real solutions when d > 0?
Answers
Answer:
Two: [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex].
Step-by-step explanation:
The question is asking for the number of real numbers [tex]x[/tex] whose square is equal to [tex]d[/tex] (where [tex]d > 0[/tex].)
Naturally, the square root of [tex]d[/tex]: [tex]\sqrt{d}[/tex] would satisfy the requirement. [tex]\left(\sqrt{d}\right)^{2} = d[/tex].
However, keep in mind that [tex](x)^2[/tex] and [tex](-x)^{2}[/tex] have the same value. Therefore, if [tex]x =\sqrt{d}[/tex] would satisfy the equation, the opposite [tex]x = -\sqrt{d}[/tex] would also do.
Since [tex]d > 0[/tex], [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would both take real values.
Because [tex]d \ne 0[/tex], the value of [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would be distinct.
Hence, [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would correspond to the two real solutions of this equation.

Slope = (difference of y-coordinates)/(difference of x-coordinates)
= (-3 - (-4))/(4 - 1) = 1/3
Answer:
slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (4, - 3) ← 2 points on the line

Step-by-step explanation:
to get this you use the point-slope formula
y-y1=m(x-x1) - plug in the coordinates and find the slope
y--3=-1(x-4) - change the sign and solve the parentheses
y+3=-x+4 - subtract 3 from both sides to get y by itself
y=-x+1

Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 12 units above the vertex of the graph of g(x) .
Which pair of functions could have been used to create the graphs of g(x) and h(x)?
h(x)=(x+12)2 and g(x)=x2
h(x)=x2−12 and g(x)=x2
h(x)=x2+12 and g(x)=x2
h(x)=(x−12)2 and g(x)=x2
Answers
Answer:
h(x) = x^2 + 12 and g(x) = x^2
Step-by-step explanation:
In this case there is a positive, vertical translation of 12 units up.
The original g(x) = x^2 has its vertex at (0, 0), whereas h(x) has its vertex at (0, 12). The function h(x) is found by adding 12 to g(x) = x^2:
h(x) = x^2 + 12
The third answer choice is the correct one: h(x) = x^2 + 12 and g(x) = x^2
