So
First find the Cos of the values using a triangle and the Pythagorean theorem
Triangle X missing side =Sqrt(5^2 - 4^2) = 3
Triangle y missing side = sqrt(13^2 - 12^2) = 5
So we now plug it into the equation
(4/5)(5/13) - (3/5)(12/13)
Multiply
4/13 - 36/65 = -16/65

What can you divide a2b5 by to get a quotient of 1?
Answers
9514 1404 393
Answer:
a^2b^5
Step-by-step explanation:
Anything divided by itself is 1.
That is, anything multiplied by its reciprocal is 1. This value (the reciprocal of the expression) is called the "multiplicative inverse." Its value is that the product of an expression and its multiplicative inverse is 1, the multiplicative identity element. (Anything times 1 is itself.)
So, to get 1 as a product, multiply by 1/(a^2b^5), which is to say, divide by a^2b^5 to get 1 as a quotient.

Show that the equation x^4/2021 − 2021x^2 − x − 3 = 0 has at least two real roots.
Answers
The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots
The equation is given as: [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] crosses the x-axis at approximately -2000 and 2000 between the domain -2500 and 2500
This means that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots

What is 3/7÷2/7
Also 3/4÷5/6
Answers
Answer:
3/7 ÷ 2/7 = 3/2
3/4÷5/6 = 9/10
Step-by-step explanation:
The key rule to understanding how to divide fractions is...
KEEP SWITCH FLIP!!!
Basically, you keep the first fraction, switch the sign from division to multiplication, and flip the other fraction...
Here's how you would go about this:
3/7÷2/7
Keep 3/7 and switch ÷ to multiplication
3/7 · 2/7
Now flip 2/7 so it becomes 7/2
3/7 · 7/2
Now multiply across!
3 · 7 = 21
7 · 2 = 14
You get 21/14...but don't forget to simplify!! Divide 21 and 14 by 7 to get 3/2!
And now...for 3/4 ÷ 5/6, you do the exact same thing!
Keep...3/4
Switch... ÷
Flip...5/6
And you should get:
3/4 · 6/5
Multiply across...
= 18/20
Simplify!
= 9/10
I hope this helps clarify any confusion you may have had!
Answer:
1 1/2 and 5/8
Step-by-step explanation:
problem 1
3/7 divided by 2/7
flip 2nd fraction then multiply is formula
so 3/7 times 7/2 which is 21/14 which is 1 7/14 simplify to 1 1/2
2
so 3/4 times 5/6 remeber formula
3/4 times 6/5
18/20 multiply numerators and denominators
you could also answer as 0.9
Suppose that Paul's checking account shows a balance of $725.35 at the beginning of the month. During this month,
he makes deposits of $472.25, $175.35, $194.50, and $317.85, and he writes checks for $150.30, $237.60,
$45.75, and $257.85. Find the end-of-the-month balance in his account.
Answers
Answer:
$ 1,193.80
Step-by-step explanation:
Balance + deposits =
725.35+472.25+175.35+194.50+317.85 = $ 1,885.30
$1,885.30 - withdrawals =
1885.30 - 150.30-237.60-45.75-257.85 = $ 1,193.80
