A hiker starts walking toward a waterfall that is 12 miles away. The hiker walks 3 miles each hour for 3 hours.
What graph represents the distance the hiker is from the waterfall over that time period?
Use the graphing tool to graph your answer.
Answers
The graph of the linear function d = 12 - 3t, representing the distance the hiker is from the waterfall over that time period, is given at the end of the answer.
What is a linear function?The slope-intercept representation of a linear function is given by the equation presented below:
y = mx + b
The coefficients of the function and their meaning are listed as follows:
m is the slope of the function, representing the change in the output variable y when the input variable represented by x increases by one.b is the y-intercept of the function, representing basically the initial value of the function.In this problem, the values of the parameters are given as follows:
m = -3, as each hour, the distance of the hiker from the waterfall decreases by 3, as he walks 3 miles each hour.b = 12, as the initial distance of the hiker from the waterfall is of 12 miles.Then the equation is:
y = 12 - 3x.
Which is graphed over the domain [0,3], as shown by the image at the end of the answer.

Answers
Answer:
125°
Step-by-step explanation:
Sum of all the internal angles in a triangle is 180°
So, we have,
67°+58°+ Adjacent angle of 1 = 180°
125°+Adjacent angle of 1 = 180°
Adjacent angle of 1 = 180° - 125° = 55°
Angle 1 and its adjacent angle are supplementary
So, Angle 1 + Adjacent angle of 1 = 180°
Angle 1 + 55° = 180°
Angle 1 = 180° - 55° = 125°
A man sold two radios at Rs. 4800 each. On one he gains 20% and on the another
he loses 20% . Find the gain or loss percent in the whole transaction.
Answers
SP of first Radio = Rs. 4800
Gain% on first radio = 20%
Find:The gain or loss percent in the whole transaction.
Solution:We know that,
CP = (100/100 + gain% ) * SP
Hence,
⟹ CP of first Radio = (100/100 + 20) * 4800
⟹ CP of first Radio = 100 * 4800/120
⟹ CP of first Radio = Rs. 4000
Similarly,
SP = (100 - loss%/100) * CP
⟹ 4800 = (100 - 20/100) * CP of second Radio
⟹ 4800 * 100/80 = CP of second Radio
⟹ Rs.6000 = CP of second Radio
Now,
Total SP of radios = 4800 + 4800 = Rs. 9600
Total CP of radios = 4000 + 6000 = Rs. 10000.
We observe that,
CP > SP
So, a loss is occured.
⟹ Loss = CP - SP
⟹ Loss = 10000 - 9600
⟹ Loss = Rs. 400
Now,
Loss% = (Loss/CP) * 100
⟹ Loss% = 400/10000 * 100
⟹ Loss% = 4%
∴ The loss occurred in the whole transaction is 4 %.
I hope it will help you.

O Vertical translation up by 5 units
O Vertical Translation down by 5 units
Vertical stretch by a factory of 5
O Reflection over the X – axis
10t
Answers
Answer:
Vertical translation up by 5 unitsExplanation:
From vertex form of quadratic function g(x)=a(x-h)²+k the h and k are coordinates of vertex transformed from point (0,0) which is the vertex of parental function f(x)=ax²
It means the h determines how many units we moved parental graph horizontaly (to the left if h<0, to the right if h>0) and the k determines how many units we moved parental graph verticaly (down if h<0, up if h>0)
g(x) = (x - 8)² + 5 ⇒ h = 8, k = 5
So if h and k are >0 it means the parental graph was moved to the right and up.

Sharon has 10 ½ gallons of paint. She plans on using 1 ½ gallons to paint each room in her house. How many rooms will she be able to paint if she shares the paint equally in each room?
Answers
Answer:
3 rooms can be fully painted if the paint is shared equally.
As well as 2/3 of another room.
Step-by-step explanation:
Sharon has 10 ½ gallons of paint. She plans on using 1 ½ gallons to paint each room in her house.
Hence:
1 ½ = 1 room
10 ½ = x
Cross Multiply
x × 1 ½ = 10 ½ × 1
x = 10 ½ × 1/1 ½
x = 11/2 ÷ 3/2
x = 11/2 × 2/3
x = 11/3
x= 3 2/3 rooms
How many rooms will she be able to paint if she shares the paint equally in each room?
Hence, she will be able to paint 3 rooms fully as well as 2/3 of another room.

How many different solutions does (x+1)(x-1)(x+2)(x+1) have?

Perhaps this will help. We have 11 identical candies, that we wish to distribute between 3 children C1. C2, and C3. (Possibly one or more of the children will get no candies.) For every solution of x1+x2+x3=11, we have a way of distributing the candies, x1 to C1, x2 to C2, and X3 to C3. conversely, every distribution of candies gives us a solution to x1+x2+x3=11.

A rectangular section of wilderness will be set aside for a new wildlife refuge. It's dimensions are 5.2 × 105meters by 3.7 × 106meters. Find the area of the land in square meters.
Answers
Answer:
The area of the land in square meters is 1.924 x 10⁷ m²
Step-by-step explanation:
Given;
length of the wilderness, L = 3.7 × 10⁶ meters
width of the wilderness, W = 5.2 × 10⁵ meters
Area of the land in square meters is given by;
A = L x W
Where;
A is the area of the land
L is length of the land
W is width of the land
A = 5.2 × 10⁵ meters x 3.7 × 10⁶ meters
A = 5.2 × 10⁵ meters x 37 × 10⁵ meters
A = 192.4 × 10⁵ m²
A = 1.924 x 10⁷ m²
Therefore, the area of the land in square meters is 1.924 x 10⁷ m²
