Madeleine owes $36,000 to a private lender. The debt grows with 12% annual interest that compounds every week. How much will Madeleine owe in one year?
Answer:
A= $40584.28
Step-by-step explanation:
P = 36000
r = 12% = 0.12
n = 52 weeks
t = 1
[tex]A = P(1 + \frac{r}{n})^{nt}\\[/tex]
[tex]=36000(1 + \frac{0.12}{52})^{52 \times 1}\\\\=36000 (1.002307)^{52}\\\\=36000 \times 1.12734\\\\=40584.28[/tex]

Hello there! Please answer this question for me please. Brainliest and 35 points!
What is the area of figure ABCD?
A
104 square inches
B
120 square inches
C
136 square inches
D
168 square inches
Answer:
That's a Trapezium
Area =½( A + B)x H
A and B are the top and bottom of the shape.
H is the height.
Substituting...
Area = ½(13+17)8
=120 Square Inches
Answer:
B. 120 in.²
Step-by-step explanation:
13 × 8 = 104 in.²
17 - 13 = 4
4 × 8 = 32
32 ÷ 2 = 16
16 in.² + 104 in.²
120 in.²

What value do you square to get 9?
Answer:
3 or -3
Step-by-step explanation:
What number multiplied by itself will give you 9
1*1 =1
2*2 =4
3*3 =9
Also note that negative times negative will be positive so
-1*-1=1
That means -3*-3 = 9
Answer:
3^2 0r (-3)^2
Step-by-step explanation:
let the number be x
x^2=9
x=[tex]\sqrt{9[/tex]
x=[tex]\sqrt{3*3[/tex]
x=3
there fore x=plus or minus 3.since it is a sqauring a number if u square (-3)^2 along will the number sign also gets multiplied and (-*-)=+ so u we get positive number.
therefore if u square 3 then u will get 9

Answer:
x = 48
Step-by-step explanation:
To solve this problem, one must assume that the segment with a length of (7) bisects the segment with a length of (x).
It is given that the segment with a length of (7) is perpendicular (forms a right angle with) the segment that has a length of (x). This is indicated by the box around one of the angles, signifiying that it is a right angle, or (90) degree angle. Therefore, the triangle with sides measuring (25) and (7) is a right triangle. Thus, one can use the Pythagorean theorem to solve for the base length. Then multiply it by (2) to find the total length of (x).
The Pythagorean theorem states the following:
[tex]a^2+b^2=c^2[/tex]
Where (a) and (b) are the legs, or sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.
[tex]a^2+(7)^2=(25)^2[/tex]
Simplify,
[tex]a^2+49=625[/tex]
Inverse operations,
[tex]a^2=576\\\\a=24[/tex]
Multiply this value by (2) to find the total side length of the segment (x),
2(a)
Substitute,
2(24)
Simplify,
48
f(x) = 3x - 1 and g(x) = x + 2, find (f+9)(x).
Answer:
what is this it looks so hard I don't have the answer
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
f(x) = 3x - 1
g(x) = x + 2
(f + g)(x) = f(x ) + g(x)
= 3x - 1 + x + 2
= 4x + 1

A triangle has a perimeter of 9x² + 7x - 2.
One side of the triangle measures 6x + 7. Another side of the triangle measures 8x?.
What is the measure of the third side of the triangle?
Answer:
9x² - 7x - 9
Step-by-step explanation:
Two sides
(6x + 7) + 8x = 14x + 7
total perimeter - two sides = Third side
9x² + 7x - 2
- (14x + 7)
––––––––––
9x² - 7x - 9
can somebody help me pleeaaassseee? 5 star rate
Answer:
x < 3/14
Step-by-step explanation:
-14x > -3
divide each side by -14
however, whenever multiplying or dividing an inequality by a negative value then you must reverse the inequality symbol
x < 3/14
Answer:
divide by -14:
[tex]x<3/14[/tex]
when you divide by a negative the sign flips

Help urgent
I need this done quick
Answer:
It is supplementary.
Step-by-step explanation:
Supplementary angles are angles that have two angles adding up to 180°. You can tell by just finding the straight line that equals 180° then seeing a line that separates the whole measurement into two angles, but together making a 180° angle still. Hope this helps! :D
Meanings of the other Options:
Alternate Interior Angles - Angles formed when two parallel or non-parallel lines are intersected by a transversal. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal.
Corresponding Angles - Angles that are in the same relative position at an intersection of a transversal and at least two lines. If the two lines are parallel, then the corresponding angles are congruent.
Alternate Exterior Angles - Angles are the pair of angles that lie on the outer side of the two parallel lines but on either side of the transversal line. Exterior angles lie on opposite sides of the transversal but outside the two parallel lines.
Parallel Lines - Two lines that never intersect. Like an equal sign for example (=).
Transversal - A line the cuts through a parallel line. Like a non-equal sign for example (≠).

Answer:
360
Step-by-step explanation:
All circles can be divided into 360 units called degrees. Since there is 270 already we subtract 270 from 360.
360 - 270 = 90
90 + 150 + 120 = 360

A rhombus has the same properties as a square. True False
Answer: True
Step-by-step explanation: am i wrong
Answer:
false
Step-by-step explanation:
in a rhombus all interior angles are not equal even though they have equal sides.while in a square all sides are equal including interior angles. so no a rhombus does not have the same properties
Rotate triangle P 90° clockwise about the point (2, -1).
Please screenshot this and send me the answers cuz I really need help :(
Answer: (2,0), (2,1), and (6,1)
Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.
I hope this helps! Have a nice day.

Which value of x is in the domain of f(t) = squared x - 7
O A. x= 8
O B. x = 0
C. x= -3
O D. x = 6
SUBMIT
Given:
The given function is:
[tex]f(x)=\sqrt{x-7}[/tex]
To find:
The value of x that is in the domain.
Solution:
Domain is the set of input values.
We have,
[tex]f(x)=\sqrt{x-7}[/tex]
We know that the square root is defined for non negative values. So,
[tex]x-7\geq 0[/tex]
[tex]x\geq 0+7[/tex]
[tex]x\geq 7[/tex]
Thus, the domain of the given function is all real number that are greater than or equal to 7.
In the given options 0, -3, 6 are less than 7 but 8 in option A is the only value that is greater than 7. So, [tex]x=8[/tex] is in the domain of the given function.
Therefore, the correct option is A.
Evaluate 32 + (7 − 2) ⋅ 4 − 6 over 3 . (1 point)
Answer:
50
Step-by-step explanation:
Given:
32 + (7 − 2) ⋅ 4 − 6/3
Using the acronym PEMDAS
P = parenthesis
E = Exponential
M = Multiplication
D = Division
A = Addition
S = Subtraction
32 + (7 − 2) ⋅ 4 − 6/3
= 32 + (5) • 4 - 6/3
= 32 + 20 - 6/3
= 32 + 20 - 2
= 52 - 2
= 50
Therefore,
32 + (7 − 2) ⋅ 4 − 6/3 = 50

The cost of having a window fixed is $100 plus $20 per hour of labor. Using h for the number of hours of labor, write an expression that represents the total cost.
Answer: 100+20h=x
Step-by-step explanation:
100 for the cost of the window Plus $20 times amount of hours the person does i equal the total amount you want to get which is x
Answer:
100 + (20 x H)
Step-by-step explanation:
100 dollars plus the amount paid for each hour of labor, so it would be 20 x H. Altogether it should be 100 + (20 x H).
