Answer:
14.5 hours/14 hours 30 minutes
Step-by-step explanation:
The distance between the two cities is 7.25•100=725 because you multiply the scale distance by the scale.The number hours is 725/50=14.5 hours because you divide the distance by 50 (the miles per hour).Nancy is knitting a scarf.

Type the correct answer in the box. If necessary, use / for the fraction bar and simplify the fraction. cos(75°)cos(15°) =
Answer:
1/4
Step-by-step explanation:
If you type cos(75)cos(15) into a scientific calculator, the answer comes out as 1/4.
The value of the trigonometric expression cos(75)cos(15) is 1/4 after applying the trigonometric identity.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a trigonometric expression:
= cos(75°)cos(15°)
As we know the trigonometric identity:
cos(a)cos(b) = (1/2)[cos(a + b) + cos(a - b)]
a = 75
b = 15
Plug the above values in the trigonometric identity:
cos(75)cos(15) = (1/2)[cos(75 + 15) + cos(75 - 15)]
cos(75)cos(15) = (1/2)[cos(90) + cos(60)]
The trigonometric ratio is the ratio of the pair of a right-angled triangle.
The value of cos90 = 0
cos60 = 1/2
cos(75)cos(15) = (1/2)[0 + 1/2]
cos(75)cos(15) = 1/4
Thus, the value of the trigonometric expression cos(75)cos(15) is 1/4 after applying the trigonometric identity.

The quotient of the synthetic division problem -1 | 2 8 6 in polynomial form is 2x + 6.
How to determine the quotient?The synthetic division problem is given;
-1 | 2 8 6
Remove the number before the | sign
2 8 6
Remove the middle number;
2 6
Introduce a variable starting from an exponent of 0 (let the variable be x);
2x¹ 6x⁰
Evaluate the exponents;
2x 6
2x + 6
Hence, the quotient of -1 | 2 8 6 in polynomial form is 2x + 6.

Which graph represents a linear function?
Answer:
If it is not a straight it is not considered a linear function. The image does not show all of the graphs, but it is not a linear function.
hence explain x²-8x+20 is always positive
Answer:
It is always positive because the discriminant is negative and therefore has no roots. This can also be interperted as the equation will always be above the x-axis on the parabola and therefore always be positive.
Step-by-step explanation:
The value of the quadratic expression (x - 4)² + 4 will be always positive.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic expression is given below.
⇒ x² - 8x + 20
Convert the expression into a vertex form, then we have
⇒ x² - 8x + 16 + 4
⇒ (x² - 2 · x · 4 + 4²) + 4
⇒ (x - 4)² + 4
Thus, the value of the expression (x - 4)² + 4 will be always positive.

Write a polynomial function f of least degree with the following zeros: 3, 4 + i
Answer:
[tex]f(x)=(x-3)(x^2-8x+17)[/tex]
Or:
[tex]f(x)=x^3-11x^2+41x-51[/tex]
Step-by-step explanation:
To find our factors, we can work backwards.
We know that 3 is a zero. This means that:
[tex]x=3[/tex]
Subtract 3 from both sides:
[tex](x-3)=0[/tex]
So, (x-3) is one of our factors.
We also know that (4+i) is a zero. So:
[tex]x=4+i[/tex]
First, let’s isolate the imaginary. So, subtract 4 from both sides:
[tex](x-4)=i[/tex]
Now, let’s square both sides:
[tex](x-4)^2=(i)^2[/tex]
Expand the left. Evaluate the right:
[tex](x^2-8x+16)=-1[/tex]
Add 1 to both sides. So, our factor is:
[tex](x^2-8x+17)=0[/tex]
Hence, our polynomial function is:
[tex]f(x)=(x-3)(x^2-8x+17)[/tex]
This is also the least degree since we did the most minimum we can do to solve backwards.
Further Notes:
If we want to convert this to standard form, we can distribute:
[tex]f(x)=(x^3-8x^2+17x)+(-3x^2+24x-51)[/tex]
Combining like terms will yield:
[tex]f(x)=x^3-11x^2+41x-51[/tex]

If 4(r + 2) – 13 = 11, what is the value of r?
Answer:
r = 4
Step by step explanation :
Step 1 : Add 13 to both sides.
4(r + 2) - 13 + 13 = 11 + 13
4(r + 2) = 24
Step 2 : Divide by 4 on both sides.
[tex]\frac{4(r+2)}{4} = \frac{24}{4}[/tex]
r + 2 = 6
Step 3 : Subtract 2 from both sides.
r = 4
The value of r is 4 in the given expression and this can be determined by using the arithmetic operation.
Given :
Expression - 4(r + 2) – 13 = 11
The following steps can be used to evaluate the given expression:
Step 1 - Write the expression.
4(r + 2) – 13 = 11
Step 2 - Add 13 on both sides in the above equation.
4(r + 2) – 13 + 13 = 11 + 13
4(r + 2) = 24
Step 3 - Multiply 4 by (r + 2) in the above expression.
4r + 8 = 24
Step 4 - Subtract 8 on both sides in the above expression.
4r + 8 - 8 = 24 - 8
4r = 16
Step 5 - Divide 4 on both sides in the above equation.
r = 4
The value of r is 4.

Answer:
a. x+6 = 0
b. y-2 = 0
Step-by-step explanation:
Given point is:
(-6,2)
a. Line perpendicular to x-axis:
A line perpendicular to x-axis means that the line is vertical and parallel to y-axis. Any equation parallel to y-axis has the form
x = k
where k is the x-coordinate of the point from which the line passes.
So the required equation is:
[tex]x = -6\\x+6 = 0[/tex]
b. Line perpendicular to y-axis:
A line perpendicular to y-axis will be a horizontal line parallel to x-axis having the equation of the form
y = b
where b is the y-intercept
Required equation is:
[tex]y = 2\\y-2=0[/tex]
Hence,
a. x+6 = 0
b. y-2 = 0
