Answer:
16. a = 13
Step-by-step explanation:
Equation: y = -4(-2) + 5
1) Multiply -4 with -2. Whenever you multiply two negatives, the product turn into a positive number; therefore, -4(-2) = 8
2) Then, add 8 and 5 which is 13.

What is the distance between the points (7, 8) and (–8, 0) on a coordinate grid?
Answer:
Hence, the distance between (7,8) and (-8,0) is:
17
Step-by-step explanation: (a,b)=(7,8) and (c,d)=(-8,0)
Hope this helps!!!!!!
The distance between the points (7, 8) and (–8, 0) = 17 units
Distance between two pointsThe distance between two points is given by the formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} [/tex]
For the line passing through the points (7, 8) and (–8, 0)
Substitute [tex]x_1=7, y_1=8, x_2=-8, y_2=0[/tex] into the equation above:
[tex]D=\sqrt{(-8-7)^2+(0-8)^2} [/tex]
This will be further simplified as shown below:
[tex]D=\sqrt{(-15)^2+(-8)^2} \\\\ D=\sqrt{225+64} \\\\ D=\sqrt{289} \\\\ D=17[/tex]
The distance between the points (7, 8) and (–8, 0) = 17 units

Answer:
(i) (x +4)^3 = x^3 +12x^2 +48x +64
(ii) (2m +1)^3 = 8m^3 +12m^2 +6m +1
(iii) (a -2b)^3 = a^3 -6a^2b +12ab^2 -8b^3
Step-by-step explanation:
Powers of a binomial have a pattern. The coefficients of the terms of the expanded product are the numbers in the corresponding row of Pascal's Triangle. Here, you want the 3rd power, so the coefficients of interest are ...
1, 3, 3, 1
The pattern is ...
(a +b)^2 = a^2 +2ab +b^2
(a +b)^3 = a^3 +3a^2b +3ab^2 +b^3
The total of powers of the variable is equal to the exponent of the binomial. The powers of the first variable decrease to 0 while the powers of the second variable increase from zero.
When 'a' or 'b' is something with a coefficient, that whole term is raised to the appropriate power.

The numbers in each row are the sums of the two numbers immediately above. For binomial expansion, you're only interested in the contents of a row. The "patterns" shown in the attachment are an extra added attraction, not particularly relevant to binomial expansion.

2. Your grandparents deposit $2000 into a bank account to start a college fund for you. They will
continue to deposit a fixed amount each month if you deposit $5 a month as well. In 36 months,
you would like to have $6500 in the account. How much will they have to contribute each
month?
Answer: $120
Step-by-step explanation:
Given the following :
Initial deposit = $2000
Let fixed monthly deposit = d + $5 ; where d = monthly amount saved by grandparents and $5 = amount saved by you
Period of deposit = 36 months = 36 monthly deposits
Total amount required at the end of 36 months = $6500
Hence ;
$2000 + 36(d + $5) = $6500
$2000 + 36d + $180 = $6500
36d = $(6500 - 2180)
36d = $4320
d = $4320 / 36
d = $120
Monthly Amount contributed by grandparents = $120

HHHEEEELLLPPPPP just 3 questions!!!!!!!!!!!!!!!!!!!!! 1. How does evaluating a function at specific points relate to graphing the function? 2. What is the process for finding x and y - intercepts from a graph? a table? an equation? 3. Can you think of a career or field of work that utilizes the skills of interpreting, comparing, and/or graphing functions? How might that career or field use the skill/concept?
Answer:
1) When we have a function y = f(x), evaluating this function in one given point (x0 for example ) is equivalent to changing the x inside the function by the value x0.
This will give us the point (x, f(x0)).
now, a graph is conformed by the set of all the points (x, f(x)).
2) The x and y-intercepts are the points where the graph intercepts the x-axis or the y-axis.
If you have a table with points (x, y), the y-intercept is the point (0, y') and the x-intercept is the point (x', 0)
Where x' and y' are known values.
If you have an equation:
y = f(x).
The x-intercept is the point (x', 0)
So you need to find the value x' such that f(x') = 0.
The y-intercept is the point (0, y')
So you need to evaluate the function in x = 0, and find the value of y.
y' = f(0).
3) The obvious answer is any science-related career, where graphs are used to transmit a lot of information with almost no words.
Another option can be an economist, where, for example, interpreting and comparing graphs can be useful to determine which option fits better the needs of a given company or what decision is better to be taken.

A sum of $ 2700 is shared among Eric, Jo and Richard. Jo's share is two times that of Richard's share. Eric's share is three times that of Jo's share. Find Eric's share.
Answer:
Eric's share is $1,800.
Step-by-step explanation:
You can write the following equations from the information given:
x+y+z=2,700 (1)
y=2z (2)
x=3y (3), where:
x=Eric's share
y= Jo's share
z=Richard's share
Now, you can replace (2) in (1) and (3) to have two equations:
x+2z+z=2,700
x+3z=2,700
x=3(2z)
x=6z
The two equations are:
x=6z (4)
x+3z=2,700 (5)
Then, you can replace (4) in (5) and solve for z:
6z+3z=2,700
9z=2,700
z=2,700/9
z=300
After this, you can replace the value of z in (4) to find x:
x=6*300
x=1800
Finally, you can replace the value of z in (2) to find the value of y:
y=2*300
y=600
According to this, the answer is that Eric's share is $1,800.

Find the equation of the exponential function represented by the table below:
x y
0 2
1 6
2 18
3 54
Answer:
y = 2[tex](3)^{x}[/tex]
Step-by-step explanation:
For the exponential function in the form
y = a[tex]b^{x}[/tex]
Use ordered pairs from the table to find a and b
Using (0, 2 ), then
2 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , thus
a = 2, so
y = 2[tex]b^{x}[/tex]
Using (1, 6 ) , then
6 = 2b ( divide both sides by 2 )
b = 3
Thus the exponential function is
y = 2[tex](3)^{x}[/tex]
divide if possible
