Answer:
$100 left over
Step-by-step explanation:
well she starts off with $300 but then spends $125 so thats
300-125= 175 she made another $250 purchase so we subtract again then added $175
175+175-250 = $100
Find the area of the shaded figure in the diagram below. Use 3.14 for π and round your answer to the nearest hundredth.
A. 39.57in^2
B. 66.89 in^2
C. 200.67 in^2
D. 118.72 in^2
Answer:
D
Step-by-step explanation:
diameter of 1 circle = 21.3/3= 7.1
radius of 1 circle= 7.1/3=3.55
area of 1 circle =πr^2=3.14× (3.55)^2=39.57
area of 3 circle= 39.57×3=118.72
therefore,area of shaded portion= area of 3 circle =118.72
If the graph of f(x)=3^x is reflected over the x-axls, what is the equation of the new graph?
Answer:
Option B
Step-by-step explanation:
By the property of reflection,
If a function [tex]'f'[/tex] is reflected across [tex]x[/tex]-axis, new function [tex]'g'[/tex] will be defined by,
[tex]g(x)=-f(x)[/tex]
Therefore, equation of the function will be,
[tex]g(x)=-(3)^x[/tex]
Option B will be the correct option.
what is the surface area of this rectangular prism?
Answer:
Step-by-step explanation:
2 surfaces that are 5x7
2 surfaces that are 4x7
and the top and bottom that are 4x5
2*5*7 = 70
2*4*7 = 56
2*4*5 = 40
total surface is 166 [tex]cm^{2}[/tex]
Answer:
166 square centimeters
Step-by-step explanation:
Surface area of a rectangular prism can be found by finding the area of each of the six surfaces of the prism. Remember that opposite sides on a rectangular prism are equal to each other, as they have the same side lengths. Because of this, the equation for surface area can be described as: 2lw + 2lh + 2wh. In this case, the length l is represented by 5cm, the width w is 4cm, and the height h is 7 cm. Now you can solve for the surface area:
SA = 2lw + 2lh + 2wh
SA = 2(5 x 4) + 2(5 x 7) + 2(4 x 7)
SA = 2(20) + 2(35) + 2(28)
SA = 40 + 70 + 56
SA = 166
Recall that units of area are given as square units, and the measure of this rectangular prism is given in centimeters. The answer is then given in square centimeters.
SA = 166 square centimeters

Solve for x when sin(4x)=1/2
the most simple answere please
Answer:
x=7.5
Step-by-step explanation:
To cancel out the sin function we need to mulitplly it by sin⁻¹ (you can usually access this button if you press 2nd-->sin)
so sin⁻¹(.5)=30
30=4x
x=7.5
The rectangle below has an area of zº +82 + 15 square meters and a width of 2 + 3 meters.
What expression represents the length of the rectangle?
Length
2 +3
2° +8x + 15
Length
meters
Answer:
(x+5) metres
Step-by-step explanation:
correct question
The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?
Area of the rectangle = Length * width
Factorize the area
A(x) = x^2+8x+15
A(x) = x^2+3x+5x+15
A(x) = x(x+3) + 5(x+3)
A(x) = (x+3)(x+5)
Since the width is x+3, the length of the rectangle will be (x+5) metres

Answer:
469 miles
Step-by-step explanation:
1 in = 125 miles
3.75 in =?
3.75 x 125 = 468.75 miles

Let A be the first sequence, and denote by [tex]a_n[/tex] the n-th term in A.
Consider the forward differences of A :
16 - 7 = 9
30 - 16 = 14
49 - 30 = 19
73 - 49 = 24
Call this sequence of first differences B, so that for n ≥ 1,
[tex]b_n=a_{n+1}-a_n[/tex]
where [tex]b_n[/tex] is the n-th term of B.
Now consider the forward differences of B, which is another sequence we'll call C :
14 - 9 = 5
19 - 14 = 5
24 - 19 = 5
Then if [tex]c_n[/tex] is the n-th term of C, we have for all n ≥ 1,
[tex]c_n=b_{n+1}-b_n=5[/tex]
which gives
[tex]b_{n+1} = b_n+5[/tex]
This tells us B is an arithmetic sequence - the first term is 9 and the difference between consecutive terms is 5, so we have for n ≥ 1,
[tex]b_n = 9 + 5(n-1) = 5n + 4[/tex]
Plug this into the recurrence for A :
[tex]a_{n+1} = a_n + b_n = a_n + 5n + 4[/tex]
We don't need to solve for [tex]a_n[/tex], fortunately; we just want the next term, which would be
[tex]a_6 = a_5 + 5^2 + 4 = 73 + 25 + 4 = \boxed{102}[/tex]

Find the term named in the problem geometric sequence and series
1). -3,-6,-12,-24 find a10
2). -2,6,-18,54 find a12
Answer: See explanation
Step-by-step explanation:
The nth term of a geometric progression is calculated by:
= ar^n-1
1). -3,-6,-12,-24 find a10
a = first term = -3
r = common ratio = -6/-3 = 2
n = 10
Using the formula
a10 = ar^n-1
a10 = -3 × 2^10-1
a10 = -3 × 2^9
a10 = -3 × 512
a10 = -1536
2). -2,6,-18,54 find a12
a = first term = -2
r = common ratio = 6/-2 = -3
n = 12
Using the formula
ar^n-1
a12 = -2 × -3^12-1
a12 = -2 × -3^11
a12 = -2 × -177147
a12 = 354294

Answer:
area = 186.984
Step-by-step explanation:
The 3 rectangular surfaces are simply L * W of each so
left surface = 5.5 * 6.2 = 34.1
right surface = 5.5 * 8.5 = 46.75
bottom surface = 5.5 * 9.8 = 53.9
The front and back are the same so
front = 1/2 base * heigth = 1/2 * 9.8 * 5.33 = 26.117
front + back = 2 * 26.117 = 52.234
total = sum them all up = 34.1 + 46.75 + 53.9 + 52.234 = 186.984
