Amelia earned $100 on a $1000 investment with a bank for a 3-year term. what rate did the bank offer her?
Answer:
3.33%
Step-by-step explanation:
Rate = 100xSI / PxT
P = 1000
SI = 100
T = 3
Rate = 100 x 100 / 1000 x 3 = 3.33%

[ (1 + p + p²)-(1 - p + p²)/(1 - p + p²)(1 + p + p²) ] - 2p/(1 - p² + p⁴) =

Find the circumference of the circle.
Answer:
the 3rd one 72.22 is the answer
Answer:
the formula for it is 2*3.14*r
so to get the radius you divide the diameter by two, so 23 divided by 2 is 11.50
so then we do 2*3.14*11.50= 77.22

2. A local t-shirt company sold 2000 t-shirts two weeks ago when they charged $10 for each shirt. The following week they sold 1120 t-shirts when they raised the price to $19 per shirt. Assuming that this rate of change continues find the following: a. Find a linear function S(p) that models the number of shirts sold as a function of the price p. b. Explain the meaning of the slope In terms of the problem. c. Predict the number of shirts the store would sell if they charged $25 for each shirt. d. If the store would like to maintain a weekly sales level of 1450 shirts how much should they charge per shirt?
9514 1404 393
Answer:
a) S(p) = -97.78p +2977.78
b) about 98 fewer shirts per week will be sold for each $1 increase in price
c) 533 shirts per week
d) $15.63
Step-by-step explanation:
a) You are given two ordered pairs: (p, s) = (10, 2000) and (19, 1120). The two-point form of the equation for a line can be used.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
s = (1120 -2000)/(19 -10)(p -10) +2000
s = -97.78(p -10) +2000
S(p) = -97.78p +2977.78
__
b) The slope is shirts/dollar, meaning about 98 fewer shirts will be sold for each dollar increase in price.
__
c) S(25) ≈ 533
At a price of $25, the store would sell about 533 shirts per week.
__
d) 1450 = S(p) = -97.78p +2977.78
-1527.78 = -97.78p
15.625 = p ≈ 15.63
The store should charge $15.63 per shirt to maintain sales of 1450 shirts per week.

Entomologists estimate that an average person consumed almost a pound of bug parts each year. There are that many insect eggs, larvae, and miscellaneous body pieces in the food we eat and the liquids we drink. The Food and Drug Administration (FDA) sets a Food Defect Action Level (FDAL) for each product. For example, the legal limit for peanut butter is 30 insect fragments per 100 grams. You just bought the crackers with 25 grams of peanut butter. What is the probability that the snack will include at least 3 crunchy critters
Answer:
0.9797
Step-by-step explanation:
We have X = number of insects in the 25bgrams of butter
Then the legal limit of concentration in peanut butter = 30 fragments/ 100 grams
Then insect amount in 25 grams =
E(X) = 30/100 x 25
= 0.3 x 25
= 7.5 fragments of insects
Using the poisson function in Excel, the probability of at least 3 crunchy critters
1 - p(X<=2)
p(X<=2) = POISSON (2, 7.5, TRUE) = 0.020156715
1 - 0.020156715
= 0.9797

Find the missing side. Round to the nearest tenth.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
1)
Hyp =40
∠48
x = Adj
use CAH since it's got these pieces in it
Cos(48) = x / 40
40* Cos(48) = x
26.76522 = x
x = 26.8 ( rounded to nearest 10th)
2)
∠29
Hyp = 35
Opp = x
use SOH since this problem has those pieces in it
Sin(29) = x / 35
35*Sin(29) = x
16.9683 = x
x = 17.0 (rounded to nearest 10th)
3)
40 = Adj
∠16
Hyp = x
use CAH again
Cos(16) = 40 / x
x = 40 / Cos(16)
x = 41.611
x = 41.6 (rounded to nearest 10th )
4)
∠55
Opp = 35
x = Adj
use TOA
Tan(55) =35/x
x = 35/Tan(55)
x = 24.5072
X = 24.5 ( rounded to nearest 10th)

Answer:
Step-by-step explanation:
[tex]Given \ f (p,q) = 8qe^{-p} + 4pe^{-q} \ where \ P_o(0,0) \\ \text{thus the gradient of f is: } \\ \\ \bigtriangledown f(p,q) = \Big(\dfrac{\partial f}{\partial p}, \dfrac{\partial f}{\partial q} \Big) \\ \\ \dfrac{\partial f}{\partial p} = -8qe^{-p} + 4pe^{-q} \\ \\ \dfrac{\partial f}{\partial p} = 8qe^{-p} - 4pe^{-q} \\ \\ Then: \bigtriangledown f(p.q) = (-4qe^{-p}+ 8qe^{-q}, 4qe^{-p}- 8qe^{-q}) \\ \\ f(0,0) = (-4*(0)e^{-0}+ 8*(0)e^{-(0)}, 4*(0)e^{-(0)}- 8*(0)e^{-(0)}) \\ \\ = (0+8,4-0) = (8.4)[/tex]
[tex]\Big| \Big | \bigtriangledown f(0,0) = \sqrt{(8)^2+4^2} \\ \\ = \sqrt{64+16} \\ \\ = \sqrt{80}[/tex]

Answer:
first one y: -3, 0, 3, 6, 12
second one y:5, 2, 0, 2, 5
Step-by-step explanation:
for the first one the equation is y=3x
so when it goes as x:-1, 0, 1, 2, 4
so you should multiply each number by 3 as the equation does
(just replace each number by x in the equation)
so y: -3, 0, 3, 6, 12
next one: equation is y=[tex]x^{2}[/tex]+1
so do the same as up there: replace x with every number
x:-2, -1, 0, 1, 2
so y will be
y:5, 2, 0, 2, 5
The millers are going to put a pool in their backyard this summer. The pool will have a depth of 5 feet, and the dimensions shown in the picture. What will be the total volume of water needed to fill the pool?
Answer:
D : 510 units
Step-by-step explanation:
NOTE:
Something to consider when solving problems like this is to break the large shape down into smaller, more managable shapes. So for this problem, you can break down this irregular shape into two rectangles. This will make solving problems similar to this easier in the future :)
WORK:
I broke down this shape into two rectangles with the following dimensions:
- 12 meters by 5 meters
- 3 meters by 14 meters
You also know that the depth has to be 5 feet (the problem itself did not account for differences in feet and meters, as when I converted the 5 feet to meters and solved that way, none of the answers were correct)
Using this information, you can now solve for the volume of each of the rectangles
12*5*5 = 300 units
3*14*5 = 210 units
Then, you simply add the two volumes together to find the total volume needed to fill the pool which equals
510 units

Step-by-step explanation:
China and the United States are playing each other in the championship match of the 1999 Women's World Cup soccer tournament. Brandi Chastain of the U.S. team is about to take a penalty kick against the Chinese team's goalkeeper, Gao Hong. Chastain will kick the ball from 18 yards away from the goal at 120 miles per hour. How many seconds does the goalkeeper have to react, dive, and reach the ball before it crosses the goal line
Answer:
The goalkeeper has 0.306 seconds to react, dive, and reach the ball before it crosses the goal line.
Step-by-step explanation:
We use the following relation to solve this question:
[tex]v = \frac{d}{t}[/tex]
In which v is the velocity, d is the distance, and t is the time.
Chastain will kick the ball from 18 yards away from the goal at 120 miles per hour.
Since the velocity is in miles per hour, the distance has to be in yards.
Each yard has 0.000568182 miles, so the ball will be kicked from 18*0.000568182 = 0.0102 miles.
This means that [tex]v = 120, d = 0.0102[/tex]
How many seconds does the goalkeeper have to react, dive, and reach the ball before it crosses the goal line?
We have to find t, first in hours. So
[tex]v = \frac{d}{t}[/tex]
[tex]120 = \frac{0.0102}{t}[/tex]
[tex]120t = 0.0102[/tex]
[tex]t = \frac{0.0102}{120}[/tex]
[tex]t = 0.000085[/tex]
An hour has 3600 seconds. So
3600*0.000085 = 0.306.
The goalkeeper has 0.306 seconds to react, dive, and reach the ball before it crosses the goal line.

A dilation centered at the origin with a scale factor of 6 is applied to this line.
A. What is the slope of the line after the dilation?
B. What is the value of the y-intercept of the line after the dilation?
Answer:
my guess would have to be
A. slope= 4
B. y-intercept= 23/3 or 7 2/3(simplified)
Step-by-step explanation:
im not sure how accurate my answer would be but what i did was put the equation in slope intercept form and added 6 for the dilatation to all factors of the equation.
The slope is 2/3.
The y-intercept is -5/3.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of the line.
6x - 3y = 5
Now,
To apply a dilation with a scale factor of 6 centered at the origin.
We multiply both sides by 6.
So,
6 (6x - 3y) = 6 x 5
Now,
Simplifying.
36x - 18y = 30
Dividing both sides by 18.
2x - y = 30/18
2x - y = 5/3
Now,
Writing in slope-intercept form.
y = mx + c
So,
y = 2x - 5/3
This means,
Slope m = 2
y-intercept c = -5/3
Thus,
The slope is 2/3.
The y-intercept is -5/3.
