Answer:
x = 6, x = 8, x = 4
Step-by-step explanation:
You would just have to come up with a number to replace x in the equation that when you multiply it by 2 it is larger than 6. Sorry if that's not the right answer.
A researcher compared the heights and shoe sizes 50 men selected at random. The equation shown describes a line of best fit for the data,
where x is the shoe size and y is the height, in inches.
y = 1.6x +48
Based on the equation, what is the approximate shoe size for a man having a height of 60 inches?
Answer: 7 1/2
Step-by-step explanation: Convert 7 1/2 to a decimal then multiply it by 1.6 to get 12.00 then add 48 to get 60.
P.S i got it right
Write an
explicit formula for An, the nth term of the sequence 7, -42, 252, ....
Answer:
[tex]A_n = 7(-6)^{n-1}[/tex]
Step-by-step explanation:
Key skills needed: Explicit formula, Geometric sequence
1) This is a geometric sequence, meaning a constant (like 6 or 3.5) is being multiplied to every term. First we need to find the constant.
This can be done by doing -42 ÷ 7 or 252 ÷ -42
-42 ÷ 7 equals -6.
252 ÷ -42 also equals -6.
2) This means that constant is -6.
3) The general form for an explicit formula of a geometric sequence is:
[tex]a_n = a_1(r)^{n-1}[/tex]
--> r means the constant (or common ratio) that is being multiplied.
--> [tex]a_1[/tex] means the first term
--> [tex]a_n[/tex] means the "nth" numbered term (so [tex]a_3[/tex] is the 3rd term, [tex]a_{10}[/tex] is the 10th term and so on).
--> [tex]n-1[/tex] is just the "n" in [tex]a_n[/tex] minus 1.
4) We can use this formula to create an explicit formula for the geometric sequence in the problem.
--> [tex]r = -6[/tex] (Since we got -6 as the constant/common ratio).
--> [tex]a_1 = 7[/tex] (Since 7 is the 1st term)
This means that our formula would be --> [tex]A_n = 7(-6)^{n-1}[/tex]
Hope you understood and have a nice day!! :D

P +78<90 solve fast pls
Answer:
p is greater ta\han or equal to 13
Step-by-step explanation:
p + 78 is greater than 90
p has to be greater than the number plus 78 that equals 90
that would be 12
p is greater than or equal to 13

f(x) = — 3х2 – 6х +5
maximum and minimum value
9514 1404 393
Answer:
maximum: 8; no minimum
Step-by-step explanation:
A graph can be useful. I find a graphing calculator handy. It shows the maximum of the function is f(-1) = 8. Since the parabola goes to -∞ for large values of x, there is no minimum.
maximum: 8
__
You can also find the maximum by putting the function in vertex form.
-3(x^2 +2x) +5 . . . . factor the leading coefficient from the x terms
-3(x^2 +2x +1) +5 -(-3)(1) . . . . add the square of half the x-coefficient, subtract the equivalent amount
-3(x +1)^2 +8 . . . . . . the vertex form of the expression for f(x)
This form is ...
a(x -h)^2 +k . . . . . with a=-3, h=-1, k=8
so the vertex is (h, k) = (-1, 8) -- the same as shown on the graph. The negative value of 'a' tells you the parabola opens downward, so the vertex is the maximum. The maximum is 8 at x = -1.
which expression is equivalent to x + x + x + 5 + 5 no mater what value substituted in for x
Answer:
3x+10
Step-by-step explanation:
Answer:
3x+10
Step-by-step explanation:
So you're going to want to count the amount of X's their are (3) and put them together (3x). Then to simplify the expression, add the 5+5 together, since they are they same type of variables. Now, you put everything together (3x+10).

When the function f(x) = 3(5)x is changed to f(x) = 3(5)x + 22, what is the effect?
Answer:
The original function is an exponential growth function, and so is a new function, but it will be translated in to 2 units.
Step-by-step explanation:
The first function will have a horizontal asymptote at y = 0 and the second function will have a horizontal asymptote at y = 22.
