9514 1404 393
Answer:
y = 1/3x 1
Stepbystep explanation:
The perpendicular line will have a slope that is the negative reciprocal of the slope of the given line. The given line's slope is the coefficient of x: 3. So, the perpendicular line's slope will be ...
m = 1/3
Only one answer choice has that value as the coefficient of x:
y = 1/3x 1
what does they y represent in the equation y=mx+b
Answer:
The yintercept of this line is the value of y at the point where the line crosses the y axis.
Stepbystep explanation:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the yintercept.

Stepbystep explanation:
Conversion
K H D____D C M
The number of miles did Tina ride when (1 mile ≈ 1.6 kilometers) so it should be considered as the 25 miles.
Calculation of the number of miles:Since
By the end of Tina’s bike ride, she traveled a distance of 40 kilometers.
And we know that
1 mile ≈ 1.6 kilometers
So,
[tex]= 40 \div 1.6[/tex]
= 25 miles
hence, The number of miles did Tina ride when (1 mile ≈ 1.6 kilometers) so it should be considered as the 25 miles.

The slope of a line is ¾. A different line passes through the points (6, 3) & (1, 5). Are the lines parallel? Why or why not?
Answer:
B. They are not parallel because their slopes are not equal.
Stepbystep explanation:
Find the slope of the line that runs through points (6, 3) and (1, 5):
[tex] slope (m) = \frac{y_2  y_1}{x_2  x_1} = \frac{5  3}{1  6} [/tex]
[tex] slope (m) = \frac{2}{7} = \frac{2}{7} [/tex]
Since the slope of the line that passes through points (6, 3) and (1, 5) is not the same with line that has a slope of ¾, therefore, both lines cannot be parallel.
The answer is "B. They are not parallel because their slopes are not equal."
What does it mean to divide a number by
a fraction (e.g., ¾)?
Answer: You can divide a number by a fraction by flipping over the fraction and multiplying them together.
Stepbystep explanation:
For example:
Lets say we wanted to divide 8 by 3/4
8÷[tex]\frac{3}{4}[/tex]
Change the division symbol into multiplication, and flip over the fraction (a great way to remember doing this is to remember the phrase Copy Dot Flip  Copy the first digit as it is, put a dot for multiplication, and then flip the fraction over)
8 ·[tex]\frac{4}{3}[/tex]
Now, just multiply and reduce/simplify the fraction if needed
Final answer is [tex]\frac{32}{3}[/tex], no need to simplify or reduce

A rocket is shot into the air. The function f (x) = 16x2 + 64x + 8 gives the
height of the rocket (in feet) as a function of the rockets horizontal distance from
where it was initially shot.
a. What was the initial height of the rocket when it was shot?
b. What is the maximum height the rocket reaches in the air?
a. The initial height of the rocket was
feet.
b. The maximum height the rocket reaches is
feet.
Answer:
A) 8 feet.
B) 72 feet
Stepbystep explanation:
We have the function [tex]f(x)=16x^2+64x+8[/tex] which gives the height of the rocket (in feet) as a function of the rocket's horizontal distance.
Part A)
We want to find the initial height of the rocket when it was shot.
At the initial height, the rocket has not moved anywhere. So, the horizontal distance will be 0.
Therefore, to find the initial height, we will substitute 0 into our function. This yields:
[tex]f(0)=16(0)^2+64(0)+8[/tex]
Evaluate:
[tex]f(0)=8[/tex]
Therefore, the initial height was 8 feet.
Part B)
Notice that our function is a quadratic.
Therefore, the maximum height will be given by the vertex of our quadratic.
To find the vertex, we use:
[tex](\frac{b}{2a},f(\frac{b}{2a}))[/tex]
Let's label our coefficients. We have [tex]16x^2+64x+8[/tex]
Therefore, a=16, b=64, and c=8.
Substitute them into the vertex formula to find the xcoordinate:
[tex]x=\frac{64}{2(16)}\\\Rightarrow x=64/32=2[/tex]
Now, to find the maximum height, substitute 2 back into our function f(x):
[tex]f(2)=16(2)^2+64(2)+8[/tex]
Evaluate:
[tex]f(2)=16(4)+64(2)+8\\\Rightarrow f(2)=64+128+8\\\Rightarrow f(2)=72\text{ feet}[/tex]
Therefore, the rocket reaches a maximum height of 72 feet.

All of the aforementioned represent the same function except: C. {(0, 1), (2, 3), (4, 5), (7, 8)}.
What is a function?A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.
The types of function.In Mathematics, there are different types of function and these include the following;
Modulus functionSignum functionPeriodic functionInverse functionPiecewise defined function.Logarithm functionFrom the first mapping, we can logically deduce the following:
when x = 1, y = 0
y = x  1
0 = 1  1
when x = 3, y = 2
y = x  1
2 = 3  1
when x = 5, y = 4
y = x  1
4 = 5  1
when x = 8, y = 7
y = x  1
7 = 8  1
For the ordered pair, we have:
when x = 0, y = 1
y = x + 1
1 = 0 + 1
when x = 2, y = 3
y = x + 1
3 = 2 + 1
when x = 4, y = 5
y = x + 1
5 = 4 + 1
Therefore, the function for these ordered pairs is equal to y = x + 1.
For the table of value, we have:
when x = 1, y = 0
y = x  1
0 = 1  1
In this context, we can reasonably infer and logically deduce that all of the aforementioned represent the same function except {(0, 1), (2, 3), (4, 5), (7, 8)}.
