A student has a total of 233 points on three tests. The scores on the first and second tests are the same. The third score exceeds the second (or the first) by 14. Find the three scores.
Answer:
Let the scores on the first two test be x
Let score for third test be 14 exceeds second( or first) = x + 14
Total = 233
x + x + (x + 14) = 233
3x + 14 = 233
3x = 219
x = 73
Score of the third test = x + 14 = 73 + 14 = 87
Therefore, the scores are 73, 73, 87

100 points!
Answer:
The interval is [4,7]
Step-by-step explanation:
The rate of change is given by
f(x2) - f(x1)
-------------------
x2 -x1
We want the rate of change to be 56
f(x2) - f(x1)
------------------- = 56
x2 -x1
We also know that the x2 is 7 so f(x2) = 192
192 - f(x1)
------------------- = 56
7 -x1
192 - f(x1) = 56( 7 -x1)
192 - f(x1) = 392 -56x1
Now we need to pick points from the table and see where it is true
(6,96)
192 - 96 = 392 -56*6
96=56 False
( 5,28)
192 - 28 = 392 -56*5
164=112 False
(4,24)
192 - 24 = 392 -56*4
168=168 True
The interval is [4,7]

Step-by-step explanation:
On simplifying (3+√3 )(5- √2), the value is
A. 112
B. 18
C. 6
D. 21
no spam and please explain ur answer .
Answer:
18
Step-by-step explanation:
( 3 + √3 ) ( 5 - √2 )
= 3 ( 5 - √2 ) + √3 ( 5 - √2 )
= 15 - 3√2 + 5√3 - √6
√2 = 1.41 ( approximately )
3√2
= 3 x 1.41
= 4.23
√6 = 2.44
√3 = 1.73
5√3
= 5 x 1.73
= 8.65
15 - 3√2 + 5√3 - √6
= 15 - 4.23 + 8.63 - 2.44
= 15 + 8.63 - 4.23 - 2.44
= 15 + 8.63 - 6.67
= 15 + 1.93
= 16.93
Rounding of 16.93 = 17
17 is near to 18.
So, 18 can be the answer.
When a graph is symmetric about the origin, it is an function.
When a graph is symmetric about the y-axis, it is an function.
A function is considered if f(-x) =
f(x), and it is considered
=
if f(-x) = -f(x).
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.

Determine the approximate value of ø
a)41.89
b) 48.20
c)33.70
d)56.30
Answer:
B,48.2
Step-by-step explanation:
To solve this we need to use SOH, CAH, TOA
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
which rounds to 48.2
THIS IS AREA OF CIRCLES PLS ANSWER
Answer:
75ft^2
Step-by-step explanation:
A = pi*r^2
The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.
Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.
3*(5)^2 = A
Simplify
3*25
Multiply
Area=75ft^2
Solve the system by elimination.
{y= 16x+44
{y= -x^2 +8x+28
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

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?
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
