Roxanna invested $10,000 in an account that earns 8.5% interest that is
compounded monthly. Determine the amount of money in the account in
15 years. (Lesson 7-10b)
Answer:
$35,100
Step-by-step explanation:
Given data
Principal=$10000
Rate= 8.5%
Time = 15 years = 180 months
The expression for monthly compounded interest is
A=P(1+r/12)^t
substitute
A=10000(1+0.085/12)^180
A=10000(1+0.007)^180
A=10000(1.007)^180
A=10000*3.51
A=$35,100
Hence the balance is $35,100
What is the equation of the line through (2, –4) and (0, 4)?A.y = 4x – 4B.y = 4x + 4C.y = –4x + 4D.y = –4x – 4SUBMITarrow_backPREVIOUS
Answer:
C
Step-by-step explanation:
I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.
Sam went to the store to buy some supplies for school. He bought a binder that cost $6.50 and packages of filler paper that cost $1.25 each. If Sam spent a total of $11.50, how many packages of filler paper did he buy? LET p = the number of packages of filler paper
Answer:
4 packages
Step-by-step explanation:
Hi,
1.25x + 6.50 = 11.50
1.25x = 5
x = 4
He bought 4 packages.

[tex]given \: that \: p = {x}^{2} + 4x - 2 \: and \: q = 2x - 1 \: and \: q - p = 2 \: find \: x[/tex]
Answer:
x= -1
Step-by-step explanation:
p= x² +4x -2 -----(1)
q= 2x -1 ------(2)
q -p= 2 -----(3)
Substitute (1) and (2) into (3):
2x -1 -(x² +4x -2)= 2
2x -1 -x² -4x +2= 2 (Expand bracket)
-x² -2x +1=2 (Simplify)
x² +2x +2 -1= 0 (Bring all terms to one side)
x² +2x +1= 0
(x +1)²= 0 (Factorise)
x +1= 0 (Square root both sides)
x= -1 (-1 on both sides)
Find the measure of the exterior angle. *
b. If 3x - 3 and 5x + 7° are the angle of a linear pair, find their measurement the angle
Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°

Find the value of f(3) for the function f(x) = -4(x+1)-2
Answer:
f(3) = - 18
Step-by-step explanation:
To evaluate f(3) , substitute x = 3 into f(x) , that is
f(3) = - 4(3 + 1) - 2 = - 4(4) - 2 = - 16 - 2 = - 18

complete the table, vertex, and max or min. <3
Answer:
Step-by-step explanation:
The function describes a parabola
for find the value of y we have to substitute the value of x in the function
x = -1
y = (-1-2)^2 =9
(-1;9)
x = 0
y = (0-2)^2 = 4
(0;4)
x = 1
y = (1-2)^2= 1
(1;1)
x = 2
y = (2-2)^2 = 0
(2;0)
x= 3
y = (3-2)^2 = 1
(3;1)
for the second part we can solve the square of the binomial
y = x^2 -4x + 4
direction of opening : we have to see if the term that multiply x^2 is positive or negative. In this case is not expessed so it is 1, a positive number.
So the direction of opening is : upwards
line of symmetry: -b/2a where b is the term that multiply x and a the term that multiply x^2
x = 4/2 = 2
vertex: the x - coordinate of the vertex is the same of the line of symmetry
so x = 2
for find the y - coordinate we have to substitute the value of x in the equation
y = 4 - 8 + 4 = 0
vertex = (2;0)
the parabola has an upwards direction of opening so it has a point of minimum that is the vertex itself.
minimum of 0

Mark rides his bike from his house to the closest edge of the park, across the length of the park, and then back home. The distance from his house to the closest edge of the park is 0.9 km and the distance from the far side of the park to his house is 1.6 km. The map shows the path Mark took on his bike. If ∠B = 85° on the map, then use the law of cosines to determine the length of the park in kilometers.
Answer:
The length of the park is approximately 1.77 kilometers
Step-by-step explanation:
The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known
The given parameters of the question are;
The distance from Mark's house to the edge of the park, a = 0.9 km
The distance from the far side of the park to Mark's house, c = 1.6 km
Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;
b² = a² + c² - 2·a·c·cos(B)
Where;
b = The length of the park in kilometers
By plugging in the known values of 'a', 'b', and 'c', we get;
b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089
∴ b = √(3.11899146089) ≈ 1.76606666377
Therefore, the length of the park, b ≈ 1.77 km.

Given:
The triangle A'B'C' is the image of triangle ABC after a translation as shown in the given graph.
To find:
The rule of translation in ARROW NOTATION.
Solution:
The general rule for translation is:
[tex](x,y)\to (x+a,y+b)[/tex] ...(i)
Where, a and b are constants.
From the given graph it is clear that the coordinate of point A are (2,3) and coordinates of point A' are (4,-2).
Using (i), the image of A(2,3) is
[tex]A(2,3)\to A'(2+a,3+b)[/tex]
We have, A'(4,-2).
[tex]A'(2+a,3+b)=A'(4,-2)[/tex]
On comparing both sides, we get
[tex]2+a=4[/tex]
[tex]a=4-2[/tex]
[tex]a=2[/tex]
And,
[tex]3+b=-2[/tex]
[tex]b=-2-3[/tex]
[tex]b=-5[/tex]
Putting [tex]a=2[/tex] and [tex]b=-5[/tex] in (i), we get
[tex](x,y)\to (x+2,y+(-5))[/tex]
[tex](x,y)\to (x+2,y-5)[/tex]
Therefore, the rule in ARROW NOTATION for the given translation is [tex](x,y)\to (x+2,y-5)[/tex].
The circle below has center Z. Suppose that m XY = 122°. Find the following.
Answer:
m∠XZY = 122°
m∠XWY = 61°
Step-by-step explanation:
From the picture attached,
A circle has been given with center as Z.
∠XZY is a central angles subtended by the arc XY,
Therefore, measure of angle XZY will be equal to measure of ∠XZY.
m(∠XZY) = m(arc XY) = 122°
By another property of the circle,
"Inscribed angle measures the half of the central angle intercepted by the same arc."
Therefore, m∠XWY = [tex]\frac{1}{2}(\angle XZY)[/tex]
= [tex]\frac{1}{2}(122)[/tex]
= 61°
