Answer:
See explanation
Step-by-step explanation:
Since banks use compound interest, then we write;
A = P(1 +r)^n
A = amount
P = principal
r= rate
n= time period
P = $7,500
n = 6
r = 6%
Substituting values;
A = P(1 +r)^n
A = 7,500(1 + 6/100)^6
A=$ 10,639
Interest = Amount (A) - Principal(P)
Interest = $ 10,639 - $7,500
Interest = $3139
Her final account balance after six years is $10,639
"All congruent triangles are similar, but all similar triangles are not congruent". Justify please!
Answer:
True similar triangles don't have to be the same size
Step-by-step explanation:
Answer:
Congruent means that the triangles are exactly the same in size and shape whereas similar means that the triangles have the same shape, but not the same size. Hope this helps!

Answer:
130.5ft²
Step-by-step explanation:
Hello There!
The figure shown is a composite figure ( so we can't find the area of it using one formula )
That being said we want to break the irregular figure into regular figures in which the area can simply be found using a formula
The figure would be broken in to the following shapes
A rectangle with a width of 4 ft and a length of 9 ft
A rectangle with a width of 8 ft and a length of 9 ft
A triangle with a height of 5 ft and a base of 9 ft
Now that we have broken the irregular figure into regular shapes we want to find the area of each individual shape
For the smaller rectangle:
The area of a rectangle can simply be calculated by multiplying the width and length
So A = 9 * 4
9 * 4 = 36
so the area of the smaller rectangle is 36ft²
For the larger rectangle
Once again the area can simply be found by multiplying the width and length
A = 8 * 9
8 * 9 = 72
so the area of the larger rectangle is 72ft²
For the triangle
To find the area of a triangle we want to use this formula
[tex]A = \frac{bh}{2}[/tex]
where b = base and h = height
We have already identified the base and height so all we have to do is plug in the values into the formula
[tex]A=\frac{5*9}{2} \\5*9=45\\\frac{45}{2} =22.5[/tex]
so the area of the triangle is 22.5ft²
Finally we add the areas of each regular figure
22.5 + 72 + 36 = 130.5
so we can conclude that the area of the composite figure is 130.5ft²

A= 530.66
Find a polynomial that has the given degree and zeros.
Degree 3 with -1, 3, and -5 as zeros
[tex]x^{3} + {?}x^{2} + {?}x + {?}[/tex]
You can write such a cubic polynomial in terms of its roots using the factor theorem:
(x - (-1)) (x - 3) (x - (-5)) = (x + 1) (x - 3) (x + 5)
Now just expand this:
(x + 1) (x - 3) (x + 5) = x ³ + (1 - 3 + 5) x ² + (-3 + 5 - 15) x - 15
… = x ³ + 3x ² - 13x - 15

Which equation has a slope of –2 and passes through the point (5, 0)?
A. y = 2x + 5
B. y = 2x + 10
C. y = –2x + 5
D. y = –2x + 10
Answer:
D. y = –2x + 10
Step-by-step explanation:
1) First, write the equation of the line in point-slope form with the given information. Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute -2 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of (5,0) into the formula as well. This gives the following equation:
[tex]y - 0 = -2(x-5)\\y = -2(x-5)[/tex]
2) Expand the right side of the equation to find the answer:
[tex]y = -2(x-5)\\y = -2x+10[/tex]
So, option D is correct.
HELP ME PLS!!!
I need help :(
Answer:
Step-by-step explanation:
Remark
I nearly found the length of a chord PQ. Be careful you don't make the same mistake. It is an arc which is part of the circumference.
Equation
Length of arc PQ = angle/360 * 2* pi * r
Givens
Angle = 110
r = 4 in
Solution
Length of arc PQ = 110/360 * 2 * 3.14 * 4
Length of arc PQ = 0.305555 * 6.28 * 4
Length of arc PQ = 7.67555
Length of arc PQ = 7.68

Moving a coordinate left will subtract from the x coordinate (left 3 means subtract 3 from x coordinate)
Moving a coordinate right will add to the x coordinate (right 3 means add 3 to x coordinate)
Moving a coordinate down will subtract from the y coordinate (down 3 means subtract 3 from y coordinate)
Moving a coordinate up will add to the y coordinate (up 3 means add 3 to y coordinate)
Reflect means flip the sign of the corresponding coordinate
reflect over x axis flip the sign of x coordinate
reflect over y axis flip the sign of y coordinate

Answer: The first solid's volume is 15/16 or 0.9375. The second solid's volume is 7/4, 1 3/4, or 1.75.
Step-by-step explanation:
First Solid
V= l*w*h
V= 5/8*3/4*2
V= 15/16
15/16 as a decimal is 0.9375
Second Solid
V= l*w*h
V= 6*7/12*1/2
V= 7/4
7/4 as a mixed fraction is 1 3/4. 7/4 as a decimal is 1.75.

You rent a boat for $1.00 per hour plus a $15.00 insurance fee. Your friend rents another boat for $4.00 per hour and no fee. For how many hours will you end up paying the same?
Answer:
5 hours
Step-by-step explanation:
x = per hour
y = total cost
You:
y = x + 15
Your friend:
y = 4x
To find the same:
y = x + 15
y = 4x (Multiply by -1)
y = x + 15
-y = -4x
0 = -3x + 15
-3x = -15
x = 5

Value of X. Please give step by step so I understand
Answer:
The value of x is 15.
Step-by-step explanation:
Since the base is 40 inches long, and the two triangles are congruent - both are right triangles and have sides x and their bases equal - you know that each base of a triangle is 20 inches long. Using the Pythagorean Theorem, you can get that [tex]x^2+20^2=25^2[/tex]. Solve for x by isolating the variable on one side: [tex]x^{2} =25^{2} - 20^{2}[/tex] ⇒ [tex]x^{2} = 625 - 400[/tex] ⇒ [tex]x^{2} = 225[/tex] ⇒ [tex]x^{2} =225[/tex] ⇒ [tex]x=\sqrt{225}[/tex] ⇒ [tex]x=15[/tex] inches.

Young company expects to double their profits every year for the next 10 years. If their profits were $5000 this year, which expression represents the profits after 10 years
A.5,000x2x10
B.5,000x2^10
C.5,000^2x10
D.5,000^10
Answer:
Suppose profits were $1
At 1 yr profit = 2 (2)^1
2 yr = 4 (2)^2
3 yr = 8 (2)^3
10 yr = 1024 (2)^10
So the correct answer should be 5000 * (2)^10
