Answer:
C. 5.8
Step-by-step explanation:
We use the Pythagoras theorem here. which is a²+b²=c².
a and b are the replacements for the 5miles and 3miles here.
They are a and b because a and b are always on the right angle side.
The longest side of this triangle is called a hypotenuse which is the c in this case.
the other sides (a and b) are called the adjacent and the opposite.
it doesn't matter if you use adjacent or opposite for a and b in this case.
the only important thing is the hypotenuse here.
So it's a²+b²=c², which is 5²+3²=c².
5² is 25 and 3² is 9, so we add them and we get 34.
so c²=34, we don't want the square on c so we send it to 34 which becomes √34.
√34 gives us 5.8 miles which is up to just only one decimal place.
You might need to use calculators for square roots because they take long to calculate.

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group of answer choices g(x) = -8x + 9 g(x) = -8x - 9 g(x) = 8x - 9 g(x) = 8x + 9
Answers
Given:
The parent function is
[tex]f(x)=8x+9[/tex]
To find:
The function after the reflection over the x-axis.
Solution:
We know that, if a function f(x) reflected over x-axis to get the function g(x), then
[tex]g(x)=-f(x)[/tex]
Putting [tex]f(x)=8x+9[/tex], we get
[tex]g(x)=-(8x+9)[/tex]
[tex]g(x)=-8x-9[/tex]
The function after the reflection over the x-axis is [tex]g(x)=-8x-9[/tex].
Therefore, the correct option is B.

Answers
Answer:
D) (0,1) (2,3) (4,5)
Step-by-step explanation:
Explanation
Given Points are A(0,1) , B(2,3) , C(4,5)
slope of the AB
[tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{3-1}{2-0} =\frac{2}{2} =1[/tex]
Slope of BC
[tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-3}{4-2} =\frac{2}{2} =1[/tex]
Therefore slope of AB and BC are equal
The three points lie on same straight line
The three points are collinear points

Answers
Answer:
one solutionStep-by-step explanation:
Given the expression
3 -x = 2+x
We re to find the number of solutions we will have:
Subtract 2 from both sides
3-x-3 = 2+x -3
-x = x -1
subtract x from both sides
-x - x = x - 1 - x
-2x =-1
Divide both sides by -2
-2x/-2 = -1/-2
x = 1/2
Since the value of x is just 1, hence the equation has just one solution.

Whats values x= 2+/- i are the the roots of the quadratic equation?
Answers
Answer:
x^2 - 4x + 5 = 0
Step-by-step explanation:
:)
x = (2 + i) and (2 - i) are the roots of the quadratic equation f(x) = x² - 4x + 5.
What are roots of a quadratic equation?The values of variables satisfying the given quadratic equation are called its roots.
Given (2 + i) and (2 - i) are roots of the quadratic equation.
Let the quadratic equation be f(x).
(x - (2 + i)) and (x - (2 -i)) are the factors of f(x).
Since, f(x) is a quadratic equation, it has only two roots.
f(x) = (x - (2 + i))(x - (2 - i))
f(x) = x² - (2 - i)x - (2 + i)x + (2 - i)(2 + i)
f(x) = x² - 2x + ix - 2x - ix + 4 - i²
f(x) = x² - 4x + 4 + 1
f(x) = x² - 4x + 5

Addison wants to ride her bicycle more than 80 miles this week. She has already ridden her Bicycle 18 miles. Write an algebraic inequality use to determine the average number of miles m she would need to ride her bicycle each day for six more days to achieve her goal?
Answers
Answer:
18 + 6m > 80
Step-by-step explanation:
We are told that:
Addison wants to ride her bicycle more than 80 miles this week.
The inequality representing this sign is given as > (greater than).
Let the number of miles be represented as= m
Hence:
She has already ridden her Bicycle 18 miles.
The algebraic inequality use to determine the average number of miles m she would need to ride her bicycle each day for six more days to achieve her goal is given as:
18 + 6 ×m > 80
18 + 6m > 80
I walk each day to school. By what percentage would I need to increase my usual average speed in order for the journey to take 20% less time than usual? C:
Answers
Answer:
25%
Step-by-step explanation:
Let v, t be the current average speed and the time taken to reach the school respectively.
As distance = speed x time, so,
distance, d=vt...(i)
Let V be the new average speed in order to to take 20% less time than t.
So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t
As distance is constant, so
d= V(0.8t)= 0.8Vt
hBy using equation (i), we have
0.8Vt = vt
0.8 V = v
V= v/0.8=1.25v
Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]
[tex]=\frac{1.25v-v}{v}\times 100[/tex]
=25%
Hence, the percentage increase in the average speed is 25%.
