you invested 5000 between two accounts paying 3% and 7% annual intrest. If the total intrst earned for the year was $310, how much was invested at each rate?
Answer:
The total interest of $320 will be the sum of the amount earned in each account.
Step-by-step explanation:
320 = x(0.04)(1) + (5000-x)(0.08)(1)
320 = 0.04x + 400 - 0.08x
-80 = -0.04x
2000 = x
5000 - x = 3000
$2,000 was invested at 4%
$3,000 was invested at 8%

Step-by-step explanation:
Hi there!
Given;
f(x) = 17x + 9
h(x) = 4x
To find: f(x)-h(x)
f(x)-h(x)= 17x + 9 - 4x
= 13x + 9
Therefore, f(x)-h(x) = 13x + 9.

what is the answer for 23/4 + -23/4 - -15/4 + 9/4
Answer:
[tex]-\frac{6}{4}[/tex]
Step-by-step explanation:
The first 2 numbers cancel, and -15/4+9/4 is the same as 9/4 - 15/4
Please mark me as brainliest if I am correct
Answer:
6
Step-by-step explanation:
In the equation, [tex]\frac{23}{4} + -\frac{23}{4} --\frac{15}{4} + \frac{9}{4}[/tex], we can see that [tex]\frac{23}{4} + -\frac{23}{4}[/tex] cancel each other out
This leaves us with [tex]--\frac{15}{4} + \frac{9}{4}[/tex]. The negatives "negate" themselves giving us [tex]\frac{15}{4} + \frac{9}{4} = \frac{24}{4}[/tex] or [tex]6[/tex]
Hopefully (some part of) this explanation makes sense (or at least somewhat). If this doesn't make sense, please tell me and I will try to make it more understandable as soon as possible.
It would help if you marked my answer as Brainliest, if I'm correct, so I can help even more people! (I would really appreciate it!)

Answer:
the point is (1.73, 3)
Step-by-step explanation:
Given a vector on an xy plot, the magnitude is the hypotinuse of the triangle formed, and the direction is the angle with x axis. So we have a right angle triangle that must be a 30-60-90 (sum = 180).
Then from the lower angle
sin(60) = opposite/hypotinuse = y/(2*3**(1/2))
0.866 = y/(2*1.732)
0.866 = y/3.464
0.866 * 3.464 = y
3 = y
Then from the top angle
sin(30) = opposite/hypotinuse = x/(2*3**(1/2))
sin(30) = x/(2*3**(1/2))
0.5 = x/(2*3**(1/2))
0.5 = x/3.464
0.5 * 3.464 = x
1.73 = x

Determine the DOMAIN in interval Notation
Answer:

Step-by-step explanation:
There are ‘n’ arithmetic means between 33 and – 3. If second last mean: second mean = 1: 5, find the value of n.
We know that:
There are n arithmetic means between the numbers 33 and -3
second last mean: second mean = 1:5
Using this, we can find that the value of n is 9.
Now let's see how we need to use the information.
"There are n arithmetic means between the numbers 33 and -3"
This means that we will have a sequence like:
33, a₁, a₂, ..., aₙ, -3
And by the given ratio, we know that:
aₙ₋₂:a₂ = 1:5
Also, because this is an arithmetic sequence we have:
a₁ = 33 + d
a₂ = 33 + d + d
aₙ ₋ ₂ = 33 + (n - 2)*d = -3 - 2*d
Because of the ratio, we will have that:
aₙ₋₂/a₂ = 1/5
We can replace what the left side by:
(-3 - 2*d)/(33 + 2*d) = 1/5
now we can solve this for d.
-3 - 2*d = (33 + 2*d)*(1/5)
5*(-3 - 2*d ) = (33 + 2*d)
-15 - 10d = 33 + 2d
-15 - 33 = 2d + 10d
-48 = 12d
-48/12 = -4 = d
So now we know that the value of d is -4.
Now we can use the equation
aₙ ₋ ₂ = 33 + (n - 2)*d = -3 - 2*d
to find the value of n:
33 + (n - 2)*d = -3 - 2*d
33 + (n - 2)*-4 = -3 - 2*-4
33 - 4n + 8 = -3 + 8
41 - 4n = 5
-4n = 5 - 41 = -36
n = 36/4 = 9
The value of n is 9.

Part A: If (2^6)^x = 1, what is the value of x? Explain your answer.
Part B: If (5^0)^x = 1, what are the possible values of x? Explain your answer.
2 points for each answer; 2 points for each explanation.
Answer:
Step-by-step explanation:
2^6 = 64 and the only power of 64 that gives us 1 is 64^0 = 1. S0 x = 1.
Now 5^0 is already 1. Then (5^0)^x =1^x is equal to 1 for any value of x.

Which fraction is greater,2/3 or 25/15?
Answer:
[tex]\frac{25}{15}[/tex] is greater.
Step-by-step explanation:
25÷15=1.67
2÷3=0.67
1.67 is greater than 0.67, so [tex]\frac{25}{15}[/tex] is greater.
Also, [tex]\frac{25}{15}[/tex] is an improper fraction, and [tex]\frac{2}{3}[/tex] is a proper fraction. Improper fraction mast be greater than a proper fraction.
How high up on a wall will a 20-foot ladder touch if the foot of the ladder is placed
4 feet from the base of the wall?
Step-by-step explanation:
by using the pythagoras theorem,
the height of the ladder touching the wall =
√(20²- 4²)
=√ (400-16)
=√384
= 8√6 feet
or 19.6 feet
Using Pythagorean theorem
[tex]\\ \rm\longmapsto P^2=H^2-B^2[/tex]
