Answer:
-6x^2+11x-4
Step-by-step explanation:
Answer:
6[tex]x^{2}[/tex]+11x-4
Step-by-step explanation:
(-3x+4)(2x-1)
Use the distributive property. The picture below will show it is supposed to be done.
i will first be using the distributive property on -3x
4(-3x(2x)-3x(-1))Complete the equation
4(2x-1)(-6x^2+3x)Now distribute the 4 into the equation.
8x-4-6[tex]x^{2}[/tex]+3xNow combine like terms
11x-4-6[tex]x^{2}[/tex]Write in standard form
-6[tex]x^{2}[/tex]+11x-4A store owner notes that 1 out of 4 customers do not make a purchase. How many customers need to come into the store in order for the owner to make 85 sales?
Answer:
340 customers.
Step-by-step explanation:
1 out of 4 = 25% purchase rate
85 × 4 = 340
To check our work:
25% of 340 = 0.25 × 340 = 85

Which of the following represents the general equation for the geometric sequence?
-1, -2, -4, …
a n = 2 n - 1
a n = -1 · 2 n - 1
a n = 1 · 2 n + 1
a n = 1 · 2 n - 1
Answer:
-1,-2,-4
an = a1 * r^(n - 1)
a1 = first term = -1
r = common ratio = 2
so the equation would be : an = -1 * 2^(n - 1)
the half-life of chromium-51 is 38 days. If the sample contained 510 grams. How much would remain after 1 year?
Answer:
About 0.6548 grams will be remaining.
Step-by-step explanation:
We can write an exponential function to model the situation. The standard exponential function is:
[tex]f(t)=a(r)^t[/tex]
The original sample contained 510 grams. So, a = 510.
Each half-life, the amount decreases by half. So, r = 1/2.
For t, since one half-life occurs every 38 days, we can substitute t/38 for t, where t is the time in days.
Therefore, our function is:
[tex]\displaystyle f(t)=510\Big(\frac{1}{2}\Big)^{t/38}[/tex]
One year has 365 days.
Therefore, the amount remaining after one year will be:
[tex]\displaystyle f(365)=510\Big(\frac{1}{2}\Big)^{365/38}\approx0.6548[/tex]
About 0.6548 grams will be remaining.
Alternatively, we can use the standard exponential growth/decay function modeled by:
[tex]f(t)=Ce^{kt}[/tex]
The starting sample is 510. So, C = 510.
After one half-life (38 days), the remaining amount will be 255. Therefore:
[tex]255=510e^{38k}[/tex]
Solving for k:
[tex]\displaystyle \frac{1}{2}=e^{38k}\Rightarrow k=\frac{1}{38}\ln\Big(\frac{1}{2}\Big)[/tex]
Thus, our function is:
[tex]f(t)=510e^{t\ln(.5)/38}[/tex]
Then after one year or 365 days, the amount remaining will be about:
[tex]f(365)=510e^{365\ln(.5)/38}\approx 0.6548[/tex]

22x4 is 88 and add the 2 zeros
Step-by-step explanation:
Answer:
0.088.
Step-by-step explanation:
0.22 * 0.4
Now 22 * 4 = 88 and
there are 3 numbers after the decimal points in 0.22 and 0.4 so there has to be 3 numbers after the decimal point in the answer, so it's:
0.088.

What is the constant in the expression 7x + 3
Answer:
3
Step-by-step explanation:
In expressions, there are 4 items to look at :
1. Terms
2. Coefficients
3. Like Terms
4. Constant Terms
Since 4. is the topic at hand, let's focus on that, constant terms are terms that cannot be changed value.
This would mean numbers without a variable, look at the expression below :
7x + 3
Since 3 doesn't have a variable, therefore 3 is a constant term.
Please be specific:(

A cashier can ring up 12 items per minute. How long will it take the cashier to ring up 72 items?
Answer:
So it will take 6 minutes to ring up 72 items.
Step-by-step explanation:
Well this seems pretty simple just have to reads the question and know what to find.
So what we know :
A cashier can ring up 12 items per minute
So :
1 minute = 12 Minutes
And we have to find :
How long for 72 items
So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.
So :
72 / 12
=
6
So it will take 6 minutes to ring up 72 items.
I hope this helps!
