Answer:
$584.92928
Step-by-step explanation:
If Sami starts with $500 and earns 4% and she doesnt take away any money, the equation would be:
y=500(1.04)^x
y being dollars and x in years
if we replace x with 4, the answers come out to be 584.92928
Answer:
Step-by-step explanation:
First, we express the annual interest rate r, in decimal form. Since it is 4%, the interest rate is
r=4%=4100=0.04.
The principal P=500, so the future value is
A=P(1+rt)=500(1+(0.04)(4))=$580.

A line passes through the point (-8, -9) and has a slope of -
5
4
Write an equation in slope-intercept form for this line.
Answer:
y = -5/4x -19
Step-by-step explanation:
It is often convenient to simplify a point-slope form of the equation.
y = m(x -h) +k . . . . . line with slope m through (h, k)
y = -5/4(x -(-8)) -9 . . . . fill in given values
y = -5/4x -10 -9
y = -5/4x -19

The customer Karen has a white rock. The rock has a mass of 14.3g and a volume of 3.2cm3. What is the density of the rock?
Answer:
The answer is 4.47 g/cm³Step-by-step explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 14.3 g
volume = 3.2 cm³
We have
[tex]density = \frac{14.3}{3.2} \\ = 4.46875[/tex]
We have the final answer as
4.47 g/cm³Hope this helps you
Answer:
The answer is 4.47 g/cm³

Answer:
Step-by-step explanation:
Explaining the Basic Concept:
This is a piecewise function, which means that it is made up of several different functions which all have different domains
In this question, we have 3 'pieces' in our piecewise function
the domain of each piece is:
1. x < -1
2. -1 ≤ x ≤ 2
3. x > 2
we will use the function related with the respective domain
Finding the values of the function:
h(-4)
Here, our input value is -4
we notice that -4 is in part of the first domain
therefore, -4 is in the domain of the first function
So, we will use the first function
h(x) = -(x/4) + 2 (for x < -1)
replacing x with -4
h(-4) = -(-4/4) + 2
h(-4) = 1 + 2
h(-4) = 3
h(1):
Here, our input value is 1
we notice that 1 is a part of the second domain
Hence, 1 is in the domain of the second function
So, we will use the second function
h(x) = -(x-1)² + 2 (for -1 ≤ x ≤ 2)
replacing x with 1
h(1) = -(1-1)² + 2
h(1) = -(0)² + 2
h(1) = 2
h(2):
Here, out input value is 2
We notice that 2 is a part of the second domain
Hence, 2 is a part of the domain of the second function
So, we will use the second function
h(x) = -(x-1)² + 2 (for -1 ≤ x ≤ 2)
replacing x with 2
h(2) = -(2-1)² + 2
h(2) = -(1)² + 2
h(2) = - 1 + 2
h(2) = 1
Therefore:
h(-4) = 3
h(1) = 2
h(2) = 1

Answer:
x=6
Step-by-step explanation:
The picture is a little unclear but I hope this is true...
To find the perimeter you need to add the sides of the triangles and the question says that the perimeters of the triangles are equal. So,...
(2x+4)+(2x)+(2x+3)=(3x+1)+(2x)+(2x)
2x+4+2x+2x+3=3x+1+2x+2x
4+2x+3=3x+1
7+2x=3x+1
2x-3x=1-7
-x=-6

The mass of a substance is 8×10⁹ micrograms. If one microgram is equal to 0.000001 grams, what is the substances mass in grams written in scientific notation?
Answer:
The mass of the substance is [tex]\mathit{8\cdot 10^{3}}[/tex] grams.
Step-by-step explanation:
Scientific Notation
The mass of a substance is [tex]8\cdot 10^9[/tex] micrograms and one microgram is 0.000001 grams.
This last unit needs to be expressed in scientific notation:
[tex]0.000001 grams = 1\cdot 10^{-6}[/tex]
The mass of the substance in grams is calculated by:
[tex]8\cdot 10^9 * 1\cdot 10^{-6}[/tex]
Multiply the magnitudes and add the exponents:
[tex]8\cdot 10^9 * 1\cdot 10^{-6}=8\cdot 10^{-6+9}=8\cdot 10^{3}[/tex]
The mass of the substance is [tex]\mathbf{8\cdot 10^{3}}[/tex] grams.

[tex]Solution: f(x)\ge-5\\Interval:[-5,\infty)[/tex]
Step-by-step explanation:
Equation: [tex]\frac{1}{4} x^2-5 = y[/tex]
1). [tex]\frac{1}{4} x^2-5 = y[/tex] →[tex]\frac{x^2}{4}-5=y[/tex]
2). [tex]\frac{x^2}{4}-5=y[/tex] ∴ [tex]a=\frac{1}{4}, b=0, c=-5[/tex]
3). [tex]x_v=-\frac{b}{2a}[/tex]
[tex]=-\frac{0}{2(\frac{1}{4})}[/tex]
[tex]=0[/tex]
4). now plug [tex]x_v[/tex] into [tex]y_v[/tex]
[tex]y_v=\frac{0^2}{4}-5[/tex]
[tex]=-5[/tex]
5). Minimum (0,-5) ∴ [tex]f(x)\ge-5[/tex]
which of the following describes controlled variables
A what you change for testing
B what you keep the same
C what you measure
Answer:
b, controlled variables are constant and unchanged
A controlled variable is what is held constant. When doing an experiment, it is ideal to only focus on one variable at a time while keeping everything else in check. This way you can compare two items effectively.
In contrast, a manipulated variable is one that is intentionally changed to see how it affects the subject. For example, if you're testing various fertilizers, then the fertilizer brand would be the manipulated variable. The soil, moisture, amount of sunlight, and other environmental factors are kept the same (each subject gets the same about of each) making them to be controlled variables.

Problem 1
Answer: Choice B) x = -2------------------
Explanation:
Add the equations straight down.
The x terms add to 5x+(-3x) = 2x
The y terms cancel out since 3y+(-3y) = 0y = 0
The right hand sides add to -7+3 = -3
After adding the equations you should get 2x = -4 which solves to x = -2
=====================================================
Problem 2
Answer: y = 4------------------
Explanation:
Since 5x = 0, this means x = 0 after dividing both sides by 5.
Use this to find y
y = -4x+4
y = -4(0)+4
y = 4
If you want the value of z, then
x = -3y+z+6
0 = -3(4)+z+6
0 = z-6
6 = z
z = 6

Answer:

Step-by-step explanation:
if 6 members has paid, then the remaining 8 will be 8 x 12.55 = 100.4
Answer:
The answer is $100.40
Step-by-step explanation:
ok. their are 14 members. 6 members payed their dues in week 1. so, subtract 6 from 14. 14 - 6 = 8. Now, the due is $12.55. 8 members payed their dues in week 2, so multiply 8 by 12.55. 8 x 12.55 = 100.50 the answer SHOULD be $100.50 i would think, but there is not an option for that. so, i would pick option 4, because that is .10 off from 100.50. Good luck!!
