An employee puts $3,000 into a retirement fund that offers 7% interest compounded annually. The employee makes no other deposits or withdrawals. Which amount is closest to the interest that the employee will have earned after 4 years?
Answers
Answer:
$840
Step-by-step explanation:
Given data
Principal = $3000
Rate= 7%
Time= 4 years
The expression for the simple interest is
SI= PRT/100
substitute
SI= 3000*7*4/100
SI= 30*7*4
SI= $840
Hence the interest is $840
640 divided by 16= 16 divided by 16 =1

Step-by-step explanation:
We can see that we need to plug in 2 for x in the first equation
We can also see that when x=2 we need to use the second part of the piecewise (because this one works when x is greater than or equal to 2)
so we have
3*(4*2+1)= 27
for g(x) we need to plug in x=1
we use the first piecewise equation because it's valid when x is less than 3
4(1²+2)=12
take their sum 27+12= 39

we have the adjacent and hypotonouse so it's easiest to use CAH
let theta (angle) = x
cos(x)=4/6
to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)
x=48.1896851

Answers
Answer:
odd; even; even; odd
Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.
Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

If a candy machine contains 76 green candies, 42 orange candies, 58 red
candies, and 24 yellow candies, what is the probability that a candy chosen at
random will be red?
Answers
Answer:
P(candy chosen is red) = 58/200
Step-by-step explanation:
0.29 is the probability that a candy chosen at random will be red.
What is probability?The probability exists the branch of mathematics involving numerical descriptions of how likely an event exists to happen, or how likely it exists that a proposition stands true. The probability of an event exists in a number between 0 and 1, where, roughly speaking, 0 reveals the impossibility of the event, and 1 demonstrates certainty.
A machine contains = 76 green candies
B machine contains = 42 orange candies
C machine contains = 58 red candies
D machine contains = 24 yellow candies
Probability = 58 / 76 + 42+ 58+ 24
= 58 / 200
= 0.29
0.29 is the probability that a candy chosen at random will be red.

5x−4y=−10
y=2x−5
x=x=x, equals
y=y=y, equals
Answers
Answer:
✎ ANSWER:-[tex]y = 2x - 5[/tex]
Substitute the value of y as 2x - 5 in the equation.
[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]
Now, find the value of y
[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]
⎇ x = x = x, equals 10
⎇ y = y = y, equals 15
Answer:
if y = 2x-5
then in the second equation we can find the value of x
5x-4(2x-5) = -10
5x-8x+20 = -10
-3x = -30
x = 10
then the value of y = 20-5 = 15
therefore the value of x = 10 and y =15 (ans)

Answer: tanA=3/4
Step-by-step explanation: If cosA=4/5 then
sinA=√(1−cos2A) {Because sin^2A+cos^2A=1}
=>sinA=√(1−16/25)
=>sinA=√(9/25)
=>sinA=3/5
Now as tanA=sinA/cosA
=>tanA=3/5×5/4 {Because 1/cosA=5/4}
=>tanA=3/4

{y= 16x+44
{y= -x^2 +8x+28
Answers
Answer:
x= -4, y= -20
Step-by-step explanation:
y= 16x+44
(y= -x²+8x+28) * (-1)
multiply both sides by -1
y= 16x+44
-y= x²-8x-28
add the equations to eliminate y
y-y= x²+16x-8x+44-28
0= x² +8x +16 this is the same with (x+4)²=0 so x= -4
go back to the first equation and substitute x with -4 and solve for y
y= 16*(-4) +44 = -64+44 = -20
