We will see that we can write the function I(x) as:
I(x) = x + 1/2.
How to get the function I(x)?
We know that I(x) is a vertical dilation of scale factor 1/2 of P(x), where:
P(x) = 2x + 1.
The vertical dilation will be written as:
I(x) = (1/2)*P(x).
If we replace P(x) by the actual function, we will get:
I(x) = (1/2)*(2x + 1) = x + 1/2.
Then we can conclude that the function I(x) is:
I(x) = x + 1/2.

Step-by-step explanation:
the area of a triangle is
baseline × height / 2
the baseline (where the height hits at a 90° angle) is 4 m.
the height is 3.7 m.
so, the area is
4 × 3.7 / 2 = 2 × 3.7 = 7.4 m²

Find the length of the third side to the nearest tenth
Answer: ≈ 1.4.
Step-by-step explanation: To find the hypotenuse of a triangle (the longest side of a triangle), you need to add the legs (the two sides of the triangle that are not the hypotenuse). You need to have ^2 when adding each leg. For example, both legs are 1 so when you're adding them, the equation should look like this--> 1^2 + 1^2. Then, once you find the answer to that, you need to find the square root of the answer. The work is done below:
1^2 + 1^2 = 2.
√2 ≈ 1.41421356 or ≈ 1.4.
Therefore, your answer is ≈ 1.4.

i know this is probably simple but ive forgotten how to do it and i cant find it in my notes help appreciated!
Answer:
This is pythagoras
A squared plus b squared equals c squared.
The unknown side is c as its the hypotenuse,
So the length of the first side is 6.4 this squared = 40.96
The other length is 12 as 6 is the radius so the diameter of the circle amd therfore the length of the triangle is 12.
12 squared is 144
144 + 40.96 = 184.96
The length of c squared is 184.96
To find the length of c alone we calculate the square root.
The square root of 184.96 = 13.6
? = 13.6

Answer:
102 mm²
Step-by-step explanation:
You can split the shape into two different shapes: a trapezium and a rectangle.
Area of rectangle = length x width
= 10 x 3 = 30mm
Area of trapezium = a + b / 2 x h
h = 9 - 3 = 6mm
= 10 + 14 / 2 x 6
= 72 mm
Total area = 72 + 30 = 102 mm²

Find the area of a regular octagon with an apothem length of 10 and a side length of 6.
Answer:
A = 240 units²
Step-by-step explanation:
the area (A) of a regular polygon is
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then
A = [tex]\frac{1}{2}[/tex] × 48 × 10 = 24 × 10 = 240 units²
Answer:
Step-by-step explanation:
Preliminary task
Draw a regular octagon.
Draw a perpendicular from the side's midpoint to the center. (That is the apothem).
Draw two radii from the center of the side to the center of of the octagon. The endpoints of these two radii is the endpoints of the octagon's side.
The octagon has 8 such triangles.
Area one triangle
Area = 1/2 * side * apothem
side = 6
apothem = 10
Area = 1/2 6 * 10
Area = 30
Area of 8 such triangles.
Area = 8 * area of 1 triangle
area 1 triangle = 30
Area of 8 such triangles = 30*8 = 240

9. A cooler contains 4.5 gallons of water and is filling up
at a rate of 0.1 gallons per second. A second cooler
contains 7 gallons of water and is draining at a rate of
0.25 gallons per second. Which could be used to
determine the number of seconds it would take for each
cooler to contain the same amount of water?
The equation that can be used to determine when each cooler would contain the same amount of water is 2.5 = 0.75t.
When the coolers would have the same amount of water?Equation that can be used to determine the amount of water in the first cooler at time t : 4.5 + 0.1t
Equation that can be used to determine the amount of water in the second cooler at time t : 7 + 0.25t
Where t represents seconds
When they have the same amount of water, the two above equations would be equal
4.5 + 0.1t = 7 + 0.25t
Combine similar terms
7 - 4.5 = 0.1t - 0.25t
2.5 = 0.75t

Answer:
X=121, y=59, w=59, z=53
Step-by-step explanation:
To find w, we know that the interior angles of a triangle are 180°. Thus ↓
180-31-90=59
For y, we know that y and w are opposite angles. Therefore, y = w = 59.
To find x, we know that there is a one straight line, so therefore we use ↓
180-59=121
Lastly, to find z, we know that the interior angles of a triangle are 180°. Thus ↓
180-59-68=53

Enola owns a small business selling ice-cream. She knows
customers paid cash, 76 customers used a debit card, and 10 customers used a credit
card. .
Based on these results, express the probability that the next customer will pay with
something other than a credit card as a decimal to the nearest hundredth.
the probability that the next customer will pay with something other than a credit card as a decimal to the nearest hundredth is 0.93.
To calculate the probability that the next customer will pay with something other than a credit card, we need to know the total number of customers who paid cash or used a debit card.
The total number of customers who paid cash or used a debit card is the sum of the customers who paid cash and those who used a debit card:
Total customers who paid cash or used a debit card = customers who paid cash + customers who used a debit card = 76 + 10 = 86
Therefore, the probability that the next customer will pay with something other than a credit card is:
P = Total customers who paid cash or used a debit card / Total number of customers
P = 86 / (76 + 10 + 1) (adding 1 to account for the next customer)
P = 0.93
So the probability that the next customer will pay with something other than a credit card as a decimal to the nearest hundredth is 0.93.
