factorise completely 15ab+24bc
To factor an expression is to rewrite the expression in a factored form
The factored expression of 15ab + 24bc is 3b(5a + 8c)
The expression is given as:
15ab + 24bc
Factor out b from the expression
15ab + 24bc = b(15a + 24c)
Factor out 3 from the expression
15ab + 24bc = 3b(5a + 8c)
The expression can no longer be factorized.
Hence, the factored expression of 15ab + 24bc is 3b(5a + 8c)

Answer:
20
Step-by-step explanation:
16/x = 80/100
16/x because 16 is your part and you are trying to find your whole (x)
80 is your part and 100 is your whole (this is from percent)
Cross multiply:
1600 = 80x
1600/80 = x
x = 20

THE TOTAL IS 20
The function f(x) is an increasing function about which little else is known about other than f(2)=7 and f'(2)=5. Find (f^-1)'(7).
Since f(x) is (strictly) increasing, we know that it is one-to-one and has an inverse f^(-1)(x). Then we can apply the inverse function theorem. Suppose f(a) = b and a = f^(-1)(b). By definition of inverse function, we have
f^(-1)(f(x)) = x
Differentiating with the chain rule gives
(f^(-1))'(f(x)) f'(x) = 1
so that
(f^(-1))'(f(x)) = 1/f'(x)
Let x = a; then
(f^(-1))'(f(a)) = 1/f'(a)
(f^(-1))'(b) = 1/f'(a)
In particular, we take a = 2 and b = 7; then
(f^(-1))'(7) = 1/f'(2) = 1/5
The function f(x) is an increasing function about which little else is known about other than f(2)=7 and f'(2)=5. Then the value of (f⁻¹)'(7) is 1/5
How did we arrive at this value?To find (f⁻¹)'(7), we can use the inverse function theorem. The formula for the derivative of the inverse function is given by:
[tex](f^{-1})'(y) = \frac{1}{f'(x)},[/tex]
where y = f(x). Since we know that f(2) = 7 and f'(2) = 5, we have x = 2 and y = 7. Substituting these values into the formula:
[tex](f^{-1})'(7) = \frac{1}{f'(2)} = \frac{1}{5}.[/tex]
Therefore,
[tex](f^{-1})'(7) = \frac{1}{5}.[/tex]

The graph of Fx), shown below, has
the same shape as the graph of
G(X)=x2 but is shifted right by 3 units
and down by 2 units. Write the
equation for F(x)
Answer:
f(x) = (x - 3)²- 2
Step-by-step explanation:
Given the graph of f(x), where it has the same shape as the graph of g(x) = x², but is shifted right by 3 units, and down by 2 units.
The horizontal translation of the parent graph parabola, g(x) = x², is represented by y = (x - h)², where the graph shifts by h units to the right, such that h > 0.
The vertical translation of the parent graph is represented by y = f(x - h)² - k, where the graph is vertically translated by |k | units downward, such that k < 0.
Therefore, the equation that represents the vertical and horizontal translations of the graph is: f(x) = (x - 3)²- 2.

Here are the options:
IF P = (-2, -4) THEN Q = (-6, -1)
IF P = (-2, -2) THEN Q = (-6, 1)
IF P = (7, -5) THEN Q = (3, -2)

A line passes through the points (3,21) and (8,26) Write a linear function rule in terms of x and y for this line.
Answer:
y = x+18
Step-by-step explanation:
I'm not too sure about the terminology but I hope this helps!
In order to find the equation of any line, one can use the equation
m (gradient) = (y1 – y2 ) ÷ (x1 – x2)(3,21) is the first named point; therefore, 3=x1 and 21=y1
Following the same logic, for the second point, 8=x2 and 26=y2.
Next, substitute these values into the equation above:
m = (21-26)÷(3-8)
m = -5/-5 = 1
Therefore, the gradient of this line is 1. So far our y=mx+c line equation has this information:
y=1x+c
Plugging in x and y values gives the y intercept (c):
21=3+c (the values from point (8,26) can also be used here)
c = 18
Therefore, the line equation is y = x + 18
As a function, this could be f(x) = x + 18 (although I'm not too sure about this part!)
I hope this helped.

45 48 $7.53 $17.56 $31.90
Answer:
About $437.25
Step-by-step explanation:
Using the table which gives the annual premium per $1000; the premium paid annually by the 40 year old male is $437.23
The total annual premium = $75000
Using the data in the table :
Annual premium per $1000 of coverage for a 40-year old male with a 10 - years life insurance policy = $5.83
The annual premium for $75,000 ;
Premium per $1000 × ($75000/$1000)
Annual premium = $5.83 × ($75,000/1000)
Annual premium = $5.83 × 75 = $437.25
Hence, the annual premium for the lifetime insurance based on the stated conditions is $437.25
The hour hand on a certain clock is 8.2 cm long. Find the tangential speed of of the tip of this hand during normal operation.
The tangential speed of the tip of this hour hand is 0.143 mm/s.
The tangential speed v = rω where r = length of hour hand = 8.2 cm = 0.082 m and ω = angular speed = 2π/T where T = period of hour hand = 60 min = 60 min × 60 s/min = 3600 s.
Substituting the values of the variables into the equation, we have
v = rω
v = r2π/T
v = 0.082 m × 2π/3600 s
v = 0.164π/3600 m/s
v = 0.5152/3600 m/s
v = 0.000143 m/s
v = 0.143 mm/s
So, the tangential speed of the tip of this hour hand is 0.143 mm/s.

Give the probability as a simplified fraction.
Answer:
1/6
Step-by-step explanation:
Probability that it does not snow either day is [tex]\frac{13}{144}[/tex]
What is probability?"Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are."
We have
The Probability that it will snow on Monday is [tex]\frac{8}{9}[/tex]
The Probability that it will snow on Tuesday is [tex]\frac{3}{16}[/tex]
According to the question,
The probability that it does not snow on Monday = 1 - [tex]\frac{8}{9}[/tex] = [tex]\frac{1}{9}[/tex]
The probability that it does not snow on Tuesday = 1 - [tex]\frac{3}{16}[/tex] = [tex]\frac{13}{16}[/tex]
So, the probability that it does not snow either day
= [tex]\frac{1}{9}[/tex] ×[tex]\frac{13}{16}[/tex]
= [tex]\frac{13}{144}[/tex]
Hence, Probability that it does not snow either day is [tex]\frac{13}{144}[/tex] .

Are the graphs of y=3x-5 and 9x+3y=1 parallel, perpendicular or neither?
Answer:
The two lines are neither parallel nor perpendicular to one another.
Step-by-step explanation:
The slope [tex]m[/tex] gives the orientation of a line.
Make sure that the equation of both lines are in the slope-intercept form [tex]y = m\, x + b[/tex] (where [tex]m\![/tex] is the slope and [tex]b[/tex] is the [tex]y[/tex]-intercept) before comparing their slopes.
The equation of the first line [tex]y = 3\, x - 5[/tex] is already in the slope-intercept form. Compare this equation with the standard [tex]y = m\, x + b[/tex]. The slope of this line would be [tex]m = 3[/tex].
Rewrite the equation of the second line [tex]9\, x + 3\, y = 1[/tex] to obtain the slope-intercept equation of that line:
[tex]3\, y = -9\, x + 1[/tex].
[tex]\displaystyle y = -3\, x + \frac{1}{3}[/tex].
Thus, the slope of this line would be [tex]m = (-3)[/tex].
Two lines are parallel to one another if and only if their slopes are equal. In this question, [tex]3 \ne (-3)[/tex]. Thus, the two lines are not parallel to one another.
On the other hand, two lines are perpendicular to one another if and only if the product of their slopes is [tex](-1)[/tex]. In this question, [tex]3\times (-3) = (-9)[/tex], which is not [tex](-1)\![/tex]. Thus, these two lines are not perpendicular to one another, either.
