Rania puts $15 000 into a savings account where it earns 4% per annum
compound interest.
a) What is her investment worth after two years?
b)How much interest has she earned?
Part (a)
I'll assume the interest compounds annually.
A = P*(1+r/n)^(n*t)
A = 15000*(1+0.04/1)^(1*2)
A = 16,224
Answer: $16,224====================================================
Part (b)
Subtract the result of part (a) and the original deposit amount to find the interest earned.
interest = A - P = 16,224 - 15,000 = 1,224
Answer: $1,224Answer:
The final balance is $16,236.48.
The total compound interest is $1,236.48
what is slope intercept form of a line?
Answer:
y= mx+c
Step-by-step explanation:
y= mx+c is the slope-intercept form of a line.
Where, m is the slope and c is the intercept.
Exapmle:
y=6x+5
In the above equation,
6 is the slope and 5 is the intercept.
Answer:
y = mx + b
Step-by-step explanation:
y = mx + b
m is the slope
b is the y-intercept
x and y are variables that represent points on the line

What is an equation of the line that passes through the points (3,-6) and
(-7, - 6)?
Answer:
If you want to show no work, the answer is y = -6
If you are required to show work:
The slope between the two points is(-6 - -6) / (-7 - 3) = 0/-10 = 0 and the y intercept has to be -6 so according to the slope intercept form of a line the equation would be y = 0x + (-6) or just y = -6

Evaluate the function when x = -1, 5, -10 *
[tex]f(x)=|x^{2} -x+3|[/tex]
fastest Correct answers gets brainliest
Step-by-step explanation:
f(x) = | x² - x + 3 |
f(-1) = |(-1)² - (-1) + 3| = |1 + 1 + 3| = |5| = 5
f(5) = |(5)² - (5) + 3| = |25 - 5 + 3| = |23| = 23
f(-10) = |(-10)² - (10) + 3| = |100 - 10 + 3| = |93| = 93

Brianna planted daffodils and tulips in her garden. She planted 4 daffodils for every 3 tulips. if Brianna planted 28 flowers in all, how many tulips did she plant?
Answer:
12
Step-by-step explanation:
4+3=7
7x4=28
3x4=12
Answer:
Step-by-step explanation:
The ratio is 4 daffodils to 3 tulips.
Let the daffodils = d
Let the Tulips = t
d/t = 4/3 Cross Multiply
3d = 4t Divide by 3
3d/3 = 4t/3 Combine
d = 4/3 * t
d + t = 28
4/3 t + t = 28 Change 1t to 3/3 t
4/3 t + 3/3t = 28 Add the fractions.
7/3 t = 28 Multiply both sides by 3/7
3/7 * 7/3t = 28 * 3/7
t = 4 * 3
t = 12
12 tulips were planted. This is the algebraic method of doing the question. If you are in an algebra class, the question really should be done this way.

The coordinates of the three vertices of a triangle are
(-2,5), (4,0), and (-2, 0). What is the area of the triangle?
Answer:
15
Step-by-step explanation:
Find side lengths.
(-2, 0) and (4, 0) are 6 apart.
(-2, 0) and (-2, 5) are 5 apart.
Triangle area is 1/2 of a rectangle [for this case].
6*5 = 30
30/2 = 15
Answer:
15 unit^2.
Step-by-step explanation:
The line between the points (4,0) an (-2, 0) is horizontal ( as the y coordinates are the same) and is of length
4- (-2) = 6 units.
The line between (-2,5) and (-2,0) is vertical and of length 5 - 0 = 5 units.
So it is a right triangle and the area is 1/2 * 5 * 6
= 15 unit^2.

Yuan makes punch by mixing cranberry juice and pineapple juice. For every 3 cups of pineapple juice, he uses 2 cups of cranberry juice. How much would make 10 cups? Please help me
call x is the amount of cup of pineapple, and y is the amount of cup of cranberry.
we have:
x + y = 10
x/y = 3/2 => x = (3/2)*y
x + y = 10
=> (3/2)y + y = 10
=> 3y + 2y = 20
=> 5y = 20
=> y = 4
x + y =10
=> x = 10 -4 = 6
=> 6 cups of pineapple and 4 cups of cranberry would make 10 cups

Given that the polynomial f(x) has 7 turning points, which of the following most accurately describes the degree of f(x)
Select the correct answer below.
The degree of f(x) is at least 8.
The degree of f(x) is at most 6.
The degree of f(x) is at least 7
O The degree of f(x) is at least 6.
The degree of f(x) is at most 8.
The degree cf) is at most 7
Step-by-step explanation:
the degree of f(x) is at least 8.
a squared function has 1 turning point.
a cubic function has 2 turning points.
and so on.
under certain circumstances some turning points or also zero points can merge into the same point.
formally they all count separately, but practically they are the same.
so, when we can SEE 7 turning points, there must be at least a degree of 8 or more.
a function with lower degree can never "create" additional turning points.
