In this question, we want to find the average rate of change of a function over an interval, it represents by how much f(x) changes when x changes by 1.
Average rate of change:
The average rate of change of a function over an interval [a,b] is given by:
[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]
In this question:
[tex]f(x) = 2x^3 + 4[/tex]
Between x = 4 and x = 6, so [tex]a = 4, b = 6[/tex]. Then
[tex]f(a) = f(4) = 2*4^3 + 4 = 132[/tex]
[tex]f(b) = f(6) = 2*6^3 + 4 = 436[/tex]
Then
[tex]A = \frac{436 - 132}{6 - 4} = 152[/tex]
Thus, the average rate of change of the function is of 152, that is, when x changes by 1, y changes by 152.

Answer:
Yes Ella has enough to make 30 mince pies
Step-by-step explanation:
Step-by-step explanation:
to make 36 mince pies you will need
400g of butter
500g of flour
300g of sugar
500g of mince meat
2 eggs
Ella has 1000g of butter
1000g of flour
500g of sugar
600g of meat
6 eggs
these ingredients are more than enough because
1000g-400g=600g-butter
1000g-500g=500g flour
500g-300g=200g sugar
600g-500g=100g mince meat
6-1= 5 eggs
if she were to follow the 36 pie recipe, which is two times the 18 pie recipe
but like I don't know, because it says a recipe for 18 mince pies, but in the box it says 12

Find The Surface Area Of The Prism
Answer:
360 cm^2
Step-by-step explanation:
Find the area of each face of the triangular prism.
Imagine the triangular prism as its net, it is composed with 2 triangular faces (these are tye bases of the prism) and 3 rectangular faces.
Areas of the 2 triangular bases (they are similar triangles):
1/2 x 8 cm x 6 cm = 24 cm^2
24 x 2 = 48 cm^2
Area of the rectangular face:
8 x 13 = 104 cm^2
Area of another rectangular face:
6 cm x 13 cm = 78 cm^2
Area of another rectangular face:
13 cm x 10 cm = 130 cm^2
Add up all the areas of all faces:
48 + 104 + 78 + 130 = 360
So the SA is 360 cm^2

Answer: IT IS CONGRUENT BY ASA POSTULATE.
Step-by-step explanation:
ACCORDING TO THE GIVEN IMAGE
CONSIDER TRIANGLE 1 AS TRIANGLE ABC AND TRIANGLE 2 AS TRIANGLE PQR
IN TRIANGLE ABC AND PQR
ANGLE B = ANGLE C ( 90 DEGREES )
AC = PR ( GIVEN IN FIGURE )
A TRIANGLE HAS SUM OF INTERIOR ANGLES AS 180 DEGREES
IF ANGLE B AND ANGLE Q ARE 90 DEGREES, ANGLE A + ANGLE C = ANGLE P + ANGLE R
WE HAVE ALREADY PROVED THAT AC = PR
If two triangles have one angle equal to one angle, two sides adjoining the equal angles equal, namely, one side adjoining the equal angles, and one opposite the equal angles, and the remaining angles either both less or both not less than a right angle, then the remaining side equals the remaining side and the remaining angles equal the remaining angles.
SO ANGLE A = ANGLE P
THEREFORE BY ASA CONGRUENCY TRIANGLE ABC IS CONGRUENT TO TRIANGLE PQR

Z=
Answer:
Step-by-step explanation:
To answer this, we need only solve for x and then use Pythagorean's Theorem to find z. We have the length of the hypotenuse which is 15, and we also have the base angle of 60. To solve for x we can use the trig ratio
[tex]cos60=\frac{x}{15}[/tex] and
x = 15cos60 which gives us that
x = [tex]\frac{15}{2}[/tex]
Now we can use Pythagorean's Theorem to find z, the other leg of the big triangle.
[tex](\frac{15}{2})^2+z^2=15^2[/tex] and
[tex](\frac{225}{4})+z^2=225[/tex] and
[tex]z^2=225-\frac{225}{4}[/tex] and getting a common denominator:
[tex]z^2=\frac{900}{4}-\frac{225}{4}[/tex] and
[tex]z^2=\frac{675}{4}[/tex] now we take the square root by simplifying the radical to get
[tex]z=\frac{15\sqrt{3} }{2}[/tex]
and that's what goes into the blanks there, one number per blank.

23. Two swimmers are training over a two-week period to increase the number of laps each can do consecutively. Swimmer A can do 14 laps to start, and increase her total by 3 laps each day. Swimmer B is charting her progress in the table below. Compare the initial values for each.
Answer:
Answer is A
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Answer is C because if swimmer A does 14 laps to start an 3 laps every day after that and on the chart swimmer B does 11 laps to start and 2 laps every day after that you would compare.
on day 3 swimmer B has 17 (shown on chart)
on day 3 swimmer A has 23 (14, 17, 20, 23)
if you would want it to complicate it 14:3 and 11:2
14 ÷ 14 is 1
3 ÷ 14 is .214
11 ÷ 11 is 1
2 ÷ 11 is .181

The angle measure of angle ∠1 is 31°.
The correct option is C.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given information:
The circle is centered at y.
As per the provided diagram,
The angle measure of an arc let a = 37°.
And b = 25°.
To find the angle measure of ∠1:
Apply formula (a + b)/2,
So as per the provided values of a = 37° and b = 25°.
Therefore,
m∠1 = (37 + 25)/2
m∠1 = 62/2
m∠1 = 31°.
Therefore, m∠1 = 31°.

what is constant in graphing ?
Answer:
the constant is the number without an x attaches to it.
Ex:
y = 2x + 9
9 is a constant because it is not attached to any x
y = x^3 + 2x^2 + 10x + 19
19 is a constant because it is not attached to any x

10 POINTS!! PLEASE HELP!!
Answer:
only the third answer is right.
Step-by-step explanation:
to solve it, we need to bring everything to the same denominator (the expression below the division line) or eliminate it completely.
how do we do it ? by multiplying everything with the same expression, so that we can eliminate the denominator for every term.
when looking for the best option I see that
(x² + 5x + 6) = (x + 2)×(x + 3)
that is great, because this covers all 3 denominators in our main expression.
so, we multiply everything by ((x+2)×(x+3)) and eliminate the denominators and the corresponding part of our multiplier.
that leaves us with
x×(x+3) + 2 = 5×(x+2)
now we simply simplify the expression
x² + 3x + 2 = 5x + 10
x² - 8x - 8 = 0
a squared equation has typically 2 solutions. and they are defined as
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = -8
c = -8
x = (8 ± sqrt(64 + 32)) / 2 = (8 ± sqrt(96))/2 =
= (8 ± sqrt(16×6))/2 = (8 ± 4×sqrt(6))/2 = 4 ± 2×sqrt(6)
x1 = 4 + 2×sqrt(6)
x2 = 4 - 2×sqrt(6)
both solutions are different from -2 or -3, therefore -2 and -3 are not solutions at all, and they cannot be extraneous solutions either for that reason.
and since we have 2 perfectly fine solutions, the answer options work no or only one solutions are wrong too.
Solve for ż in the following equation: 1 - iz=-1 +iz (where i? = -1). Simplify your answer as much as possible.
Answer:
z = -i
Step-by-step explanation:
1 - iz=-1 +iz
Add iz to each side
1 - iz+iz=-1 +iz+iz
1 = -1 +2iz
Add 1 to each side
1+1 = -1+1 +2iz
2 = 2iz
Divide by 2
2/2 = 2iz/2
1 =iz
Divide by i
1/i = iz/i
1/i =z
Multiply the left by i/i
i/i^2 = z
i/-1 =z
-i =z

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Rigid transformations are transformations that do not change the size or shape of the object. Types of rigid transformations are rotation, reflection and translation.

F(x) = 6x+2, find f (x+3)
Answer:
6x+20
Step-by-step explanation:
F(x) = 6x+2
f(x+3) means replace x with x+3
F(x+3) = 6(x+3)+2
= 6x+18+2
= 6x+20
Answer:
A; F(x+3) = 6x^2 + 20x + 6
Step-by-step explanation:
To find it you just would multiply F(x) onto the other side. So it would look like this:
F(x+3) = 6x + 2 (x+3)
F(x+3) = 6x^2 + 2x + 18x + 6 *combine like terms getting you
F(x+3) = 6x^2 + 20x + 6
