Richard was faster on Sunday than Saturday.
What is average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.
The formula for average speed is found by calculating the ratio of the total distance traveled by the body to the time taken to cover that distance.
Average Speed = Total Distance traveled/Total Time taken
The average speed equation is articulated as:
Given,
Richard on Saturday,
kayaked distance = 7kms.
Time taken = 2 hours
Speed = Distance/ Time
Speed on Saturday = 7/2
Speed on Saturday = 3.5 km/hr.
Richard on Sunday,
kayaked distance = 12kms.
Time taken = 3 hours
Speed = Distance/ Time
Speed on Sunday = 12/3
Speed on Sunday = 4 km/hr.
Hence, by the above calculation Richard was 0.5 km/hr. faster on Sunday than Saturday.

Let f(x)=4^x. The new function g(x)=f(x-1)+3 represents transformations that were made to function f.
Write the new equation for g.
G=
Answer:
[tex]g(x) = 4^{x-1} + 3[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4^x[/tex]
[tex]g(x) = f(x-1) + 3[/tex]
Required
Determine g(x)
First, we need to calculate f(x-1)
Given that:
[tex]f(x) = 4^x[/tex]
Subtract 1 from x
[tex]f(x-1) = 4^{x-1}[/tex]
Add 3 to both sides
[tex]f(x-1) + 3 = 4^{x-1} + 3[/tex]
Recall that:
[tex]g(x) = f(x-1) + 3[/tex]
This implies that:
[tex]g(x) = 4^{x-1} + 3[/tex]
Sophia is making tomato sauce. She adds 12 grams of her secret ingredient to each liter of sauce she prepares. If she has 4 grams of her secret ingredient, how many liters of sauce can she make?
Answer:
[tex]\frac{1}{3}[/tex]liter
Step-by-step explanation:
To make her tomato sauce,
Sophia adds 12g to 1 liter of sauce;
Let us find the;
liter of sauce per gram of ingredient = [tex]\frac{1}{12}[/tex]liter/gram
Now;
liters of sauce required to make 4grams
liter of sauce = 4g x [tex]\frac{1}{12}[/tex]liter/g = [tex]\frac{1}{3}[/tex]liter

Last one: y = -6x-1
Step-by-step explanation:
If you graph the point (-1,5) and go down 6, right 1, the y-intercept will be at -1. That is what -1 represents. The slope of -6 is in the coefficient for x. Therefore, the answer is y = -6x - 1. Hope this helped.

is 40m, 50m, 60m a right triangle
The triangle with sides 40m, 50m, 60m is not a right angled triangle .
What is Pythagoras' theorem?Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
Pythagoras' theorem :
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
According to the question
Sides of triangle are 40m, 50m, 60m
As hypotenuses is the largest side
Applying Pythagoras' theorem
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
[tex]60 ^{2} = 40^{2} + 50^{2}[/tex]
3600 ≠ 1600 + 2500
3600 ≠ 4100
Hence, The triangle with sides 40m, 50m, 60m is not a right angled triangle ,

What is the correct factorization of:
x? - 11x + 18
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)
