Answer:
26. B(t) = 500·1.075^t; B(6) ≈ $772
27. G(t) = 70·0.72^t; G(3) ≈ 26 g
Step-by-step explanation:
The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.
__
26. B(t) = 500·1.075^t
B(6) = 771.65
The balance after 6 years is about $772.
__
27. G(t) = 70·0.72^t
G(3) = 26.127
About 26 grams are left after 3 days.
The student council has $800 to spend on homecoming t-shirts. The number of t-shirts they can buy is a function of the price of the price of the t-shirt p, in dollars, given by n(p)= 800 over p. As p gets larger and larger, what does the end behavior of the function tell you about the situation? *
Answer:
n will get lower and lower
Step-by-step explanation:
In this equation the number of shirts is being multiplied by the price of each individual shirt and ultimately equals a total of $800. This means that the total must always be equal to $800 and cannot surpass it or be blow this value. Therefore, if the value of p gets larger and larger the less the number of shirts (n) that the students will be able to buy. This is the only way for the total cost to remain steady.

what's the circumference of a circle is C centimetres. which expression best represents the value of pie?
Answer:
C=2πr
Step-by-step explanation:
Answer:
ok
Step-by-step explanation:
Give the center and radius of the circle x2+y2=25
A) (2,3)r=5
B) (0,0)r=5
C) (0,0)r=25
D) (3,2)r=25
Answer:
B) (0,0); r=5
Step-by-step explanation:
A circle's standard form is (x-h)^2+(y-k)^2=r^2
The center is (h, k) and the radius is r.
So, here the center would be (0, 0) and the radius would be square root 25, or 5.
Answer:
(0,0) r=5

The living room in the house has an area off 244 square feet and a width of 14 feet what is the length of the room
Answer:
14
Step-by-step explanation:
So if its 224 square feet and the width if 14 feet the length should be 14 also I think lol Here , imagine a square put 224 inside it for the area , then put down 14 on top and bottom because its the width , multiple 14×14=56+140=196+14=210+14=224 And the last 14's are the length which u have to add Im not sure if that made any sence lol but I hope it did .
Parallel Lines
How do you know two lines are parallel?
Determine if any of the sets of lines are parallel. Justify your answer.
Line a passes through (-2, 4) and (3, 14).
Line b passes through (7, 2) and (-1, 3).
Line c passes through (3, 1) and (0, -5).
Line a: y= -13x+4
Line b: 3x-y=7
Line c: 6x + 2y = 12
Write the equation of the line parallel to x+4y = 6 that passes through the point (4, -8).
How do you know two lines are parallel?:
if the lines were to continue forever they would NEVER EVER touch they would just go STRAIGHT like train tracks

what is the answer to w²-15w =0
Answer:
w = (0, 15)
Step-by-step explanation:
w²-15w =0
w(w-15)=0
w=0 , w=15
if w=0
0(0-15)=0
0(-15)=0
0=0
if w=15
15(15-15)=0
15(0)=0
0=0
Find the perimeter and the area of the figure.
6 cm
7 cm
9.5 cm
6.5 cm
The perimeter and the area of the composite figure are 29 centimeters and 49.5 square centimeters, respectively.
How to determine the perimeter and the area of the figure
In this problem we have the representation of a composite figure, the result of the combination of a rectangle and a triangle. The perimeter of the figure is the sum of the sides and the area of the composite figure is the result of suming the areas of the rectangle and triangle:
Rectangle
A = b · h
Triangle
A = 0.5 · b · h
Where:
b - Baseh - HeightA - AreaAnd the perimeter and the area of the composite figure are now computed:
Perimeter
p = 6 cm + 7 cm + 6.5 cm + 9.5 cm
p = 29 cm
Area
A = 0.5 · (6 cm) · (2.5 cm) + (6 cm) · (7 cm)
A = 7.5 cm² + 42 cm²
A = 49.5 cm²

Based on the diagram, which expresses all possible
lengths of segment AB?
A. AB = 25
B. 27 < AB <81
C. AB = 85
D. AB < 27 or AB > 81
Answer:
B
Step-by-step explanation:
Given 2 sides of a triangle then the third side is in the range
difference of 2 sides < AB < sum of 2 sides , that is
54 - 27 < AB < 54 + 27
27 < AB < 81 → B
