Answer:
1/2(n-5)
9
Step-by-step explanation:
n less 5 = n - 5
if she finds the half of the difference, divide the difference by 2 = 1/2(n-5)
If n = 23
1/2 x (23 - 5)
= 1/2 x 18 = 9

Building A is 490 feet tall and Building B is 754 feet tall. If the angle of depression from the top of Building B to the top of Building A is 46°, how far apart are the buildings?
Answer: [tex]254.94\ ft[/tex]
Step-by-step explanation:
Given
Building A is 490 feet tall and building B is 754 ft tall.
If the angle of depression from building B to the top of building A is [tex]46^{\circ}[/tex]
Difference in the height of the two buildings is [tex]754-490=264\ ft[/tex]
If the difference between them is [tex]x[/tex]
From the figure, we can write
[tex]\Rightarrow \tan 46^{\circ}=\dfrac{264}{x}\\\\\Rightarrow x=\dfrac{264}{\tan 46^{\circ}}\\\\\Rightarrow x=254.94\ ft[/tex]
Therefore, the two buildings are [tex]254.94\ ft[/tex] apart.

Find the input (x) of the function y = 1/4x+ 12 if the output
(y) is 6
Answer:
x = -24
Step-by-step explanation:
y = 1/4x+12 (Substitute 6 for y)
6 = 1/4x+12 (Subtract 12 from both sides)
6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal
4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)
-24 = x
Answer:
y=1/4x+12
6=1/4x+12
1/4x=6-12
1/4x=-6
0.25x=-6
x=-6÷0.25
x=-24
Step-by-step explanation:
first put the given value into the equation

What is the inverse of the function f(x) = 2x + 1?
o hex) = x-1
h(x) =
10x) = 3x-2
h(x) = 5x + 2
Answer:
y = x /2 - 1/2
Step-by-step explanation:
y = h(x)
y = 2x + 1 Interchange x and y
x = 2y + 1 Subtract 1
x - 1 = 2y Divide by 2
x/2 - 1/2 = y
y = x/2 - 1/2

Which are steps in the process of completing the square used to solve the equation 3 – 4x = 5x2 – 14x? Check all that apply.
3 = 5(x2 + 2x)
3 = 5x2 – 10x
4 = 5(x2 – 2x + 1)
8 = 5(x2 – 2x + 1)
3 = 5(x – 1)2
4 = 5(x – 1)2
StartFraction 8 Over 5 EndFraction = (x – 1)2
Answer:
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
Step-by-step explanation:
3-4x=5x^2-14x
3=5x^2-14x+4x
3=5x^2-10x
5x^2-10x-3=0
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
8/5=x^2-2x+1
Cross product
8=5(x^2-2x+1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
Answer:
3 - 4x = 5x2 - 14x
= 3 - 5x2 = - 14x + 4x
= 3 - 10 = 10x
= 7 = 10x
= x = 7/10
= x = 0.7

Yuri is 5 miles from home he walks home at a speed of 1.5 miles per hour. The variable x represents time in hours and y represents yuri's distance from home in miles. Which equation models this solution
Answer:
1.5x= y
Step-by-step explanation:
Speed = distance / time
The variable x represents time in hours and y represents yuri's distance from home in miles.
Therefore
Speed = y/ x
But distance = 5 miles and speed= 1.5 miles
1.5 = y/x
or
1.5x= y
How would someone Algebraically determine X-Y intercepts?
Answer:
y-int: -6
x-int: -2/5 and 3
Step-by-step explanation:
you can find the y-intercept by substituting zero in for every 'x' in the equation;
y = 5(0) - 13(0) - 6
y = -6
to find the x-intercept(s), factor the trinomial by trying to find a pair of factors that multiply to 6 and add to -13; the factors that work are:
(5x + 2)(x - 3)
now set each factor equal to zero and solve for 'x':
5x + 2 = 0
5x = -2
x = -2/5
x - 3 = 0
x = 3

8. A cellphone company charges $29.99 per month for the first 500 minutes of calls and $0.30 a minute for any calls over the 500-minute limit. . Last month Demetria made 615 minutes of calls on her cellphone. Excluding tax, what were the total charges for her cellphone calls last month? A. $29.99 B. $34.50 C. $64.49 D. $184.50
Answer:
C) $64.49
Step-by-step explanation:
let 'x' = #minutes
cost = 29.99 + 0.3(x-500)
= 29.99 + .3(115)
= 29.99 + 34.50
= $64.49

what is the area of triangle EDF?
Answer:
4.5
Step-by-step explanation:
∠BAC ~ ∠EDF means that the triangles are similar. So the legs of the triangle share the same proportions, even if the sizes are different.
Since they share the same proportions, the same operations can be performed on each base to find the area.
The answer can be found with the knowledge that the area of a triangle is half of the height * width. You know the width of ∠BAC is 4, and the area is 8, so 16 (the area doubled) / 4 is the height. The width and height of ∠BAC are the same, and since the proportions are also the same, the width and height of ∠EDF are both 3. So the area is the width (3) times the height (3) divided by 2.
3*3 = 9
9/2 = 4.5
So the area is 4.5
Stephen is merging onto a highway. The increase in Stephen's speed for the first 8 seconds can be described by the function f(t)=t2+13t, where t is time in seconds. Which is the average rate of change of f(t) between t=2 and t=6?
Answer:
21m/s
Step-by-step explanation:
The average rate of change is expressed as;
A(t) = f(b) - f(a)/b-a
a = 2, b = 6
f(2) = 2² + 13(2)
f(2) = 4 + 26
f(2) = 30
f(6) = 6² + 13(6)
f(6) = 36 + 78
f(6)= 114
b- a = 6-2
b-a = 4
Substitute;
A(t) = 114 - 30/4
A(t) = 84/4
A(t) = 21
Hence the average rateof change is 21m/s

i want to fined out the digree of polynomial 5 x^4 + 3 x^2 + 1
Answer:
4
Step-by-step explanation:
The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.
Example, the degree of 4x^8 is 8.
So the degree of 5x^4 is 4.
The degree of 3x^2 is 2.
The degree of 1 is 0 since there is no variable in this expression.
So the degree of 5 x^4 + 3 x^2 + 1 is 4.
