What is the rate of change of the function shown on the graph? Round to the nearest tenth.
Can someone help me with this math homework please!
Answer:
negative
Step-by-step explanation:
Let,
x1 = 0
x2 = 1
y1 = 50
y2 = 44
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 44 - 50 ) / ( 1 - 0 )
= - 6 / 1
= - 6
- 6 is a negative number.
So, the slope is negative.
2. The parameter "b": Compare the graphs of several different exponential growth functions in
Mathematica to discover the significance of the parameter "b". Explain in detail what the
parameter "b" tells you about the graph of an exponential growth function.
Answer:
See explanation
Step-by-step explanation:
Required
The significance of "b" in exponential function
An exponential function is represented as:
[tex]y = ab^x[/tex]
In the above equation, parameter "b" is the rate of the function
In other words, the constant multiplier of the function.
Take for instance;
[tex]y = 2*4^x[/tex]
By comparison:
[tex]b = 4[/tex]
Another instance is:
[tex]y = 2(-4)^x[/tex]
By comparison
[tex]b = -4[/tex]
Other significance of parameter b are:
If [tex]b > 0[/tex] then b represents a growth factor
If [tex]b < 0[/tex] the b represents the factor of decay
[tex]b \ne 0[/tex] i.e. b is never 0

Write an equation of the line that passes through the point (6, -9) with the given slope m = 3.
Answer:
y = 3x - 27
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , then
y = 3x + c ← is the partial equation
To find c substitute (6, - 9) into the partial equation
- 9 = 18 + c ⇒ c = - 9 - 18 = - 27
y = 3x - 27 ← equation of line

Answer: x = 16.9
Concept:
Here, we need to know the idea of basic trigonometry.
Sine = Opposite / Hypotenues = O / H
Cosine = Adjacent / Hypotenues = A / H
Tangent = Opposite / Adjacent = O / A
Solve:
Angle θ = 50°
Opposite = x
Hypotenues = 22
Given formula
Sine = Opposite / Hypotenues
Substitute the value into the formula
sin (50) = x / 22
Multiply 22 on both sides
sin (50) × 22 = x/22 × 22
x = 22 sin (50)
x = 16.9
Hope this helps!! :)
Please let me know if you have any questions

Today only, a desk is being sold at a 33% discount. The sale price is $268. What was the price yesterday?
Discount percent = 33%
Sale price = $268
Let the original price be $x.
So,
[tex]x - (33\% \: of \: x) = 268 \\ = > x - ( \frac{33}{100} \times x) = 268 \\ = > x - ( \frac{33x}{100}) = 268 \\ = > \frac{100x}{100} - \frac{33x}{100} = 268 \\ = > \frac{(100x - 33x)}{100} = 268 \\ = > \frac{67x}{100} = 268 \\ = > 67x = 268 \times 100 \\ = > 67x = 26800 \\ = > x = \frac{26800}{67} \\ = > x = 400[/tex]
So, yesterday the price was $400.

Factor the following polynomial 9x2 + 21x – 18
Answer:
factors are
21 and x
Step-by-step explanation:
equation 9 × 2 + 21x - 18
terms 9 , 2, 21x, -18
factors 21x = 21 and x
Answer:
3(x + 3)(3x - 2)
Step-by-step explanation:
Given
9x² + 21x - 18 ← factor out 3 from each term
= 3(3x² + 7x - 6) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 6 = - 18 and sum = + 7
The factors are + 9 and - 2
Use these factors to split the x- term
3x² + 9x - 2x - 6 ( factor first/second and third/fourth terms )
3x(x + 3) - 2(x + 3) ← factor out (x + 3) from each term
(x + 3)(3x - 2)
Then
9x² + 21x - 18 = 3(x + 3)(3x - 2) ← in factored form

Find the measure of one exterior angle for the following regular polygon
What is the prime factorization of 750
can someone please help me with this question!
Answer:
A
Step-by-step explanation:
The x value of the center = 0
The y value of the center = 220/2 + 11 = 110 + 11 = 121
so the center is at (0,121)
The radius is 220/2 = 110
The equation of the Ferris Wheel is
x^2 + (y - 121)^2 = 110^2
x^2 + (y - 121)^2 = 12100

Answer:
A=35 degrees, B=55 degrees, C=110 degrees
Step-by-step explanation:
The 35 degree given angle is vertical angles with A, so they are congruent
The sum of angles in a triangle is 180, and we already have 2 angles (35 and 90) so subtract those and you get 55
angle c and the other given angle (70 degrees) are supplementary so subract 70 from 180
A 1-pound bag of sunflower seeds provides 96 grams of protein, There
are 58.5 grams of protein in a 6.5-ounce bag of pumpkin seeds. Which
type of seed has more grams of protein per ounce? How many more
grams of protein are there in 24 ounces of the higher-protein seeds?
Answer:
Pumpkin seed has more grams of protein per ounce
216 grams of protein
Step-by-step explanation:
1 pound = 16 ounce
16 ounce of sunflower seeds = 96 grams of protein
6.5 ounce of pumpkin seeds = 58.5 grams of protein
Which type of seed has more grams of protein per ounce?
Sunflower seeds:
Protein per ounce = 96 grams / 16 ounce
= 6 grams of protein per ounce
Pumpkin seeds:
Protein per ounce = 58.5 grams / 6.5 ounce
= 9 grams of protein per ounce
Therefore,
Pumpkin seed has more grams of protein per ounce
How many more grams of protein are there in 24 ounces of the higher-protein seeds?
Quantity of protein = 24 ounces ×
9 grams of protein per ounce
= 216 grams of protein

Patricia has $34,000 to invest. She invests some at 17% and the balance at 20%. Her total annual interest income is $6245. Find the amount invested at each rate
Answer:
she invest $18,500 at the 17% rate and $15,500 at the 20% rate.
Step-by-step explanation:
Suppose that you invest some quantity A to an invest rate of x%
At the end, the amount you will have is given by:
Amount = A + A*(x%/100%)
Where:
A*(x%/100%) is the interest income
So, here she initially has $34,000
And she invest some quantity X to a 17% and a quantity Y to 20%
Then we have:
X + Y = $34,000
And we know that her total anual income is $6245
X*(17%/100%) + Y*(20%/100%) = $6245
Then we have a system of two equations:
X + Y = $34,000
X*(17%/100%) + Y*(20%/100%) = $6245
First we can rewrite the second one to a more simpler form:
X*(0.17) + Y*(0.20) = $6245
Now we can isolate one of the variables in the first equation to get:
X = $34,000 - Y
Now we can replace that in the other equation to get:
( $34,000 - Y)*0.17 + Y*0.20 = $6245
Now we can solve this for Y:
$34,000*0.17 + Y*(0.20 - 0.17) = $6245
$5,780+ Y*0.03 = $6245
Y*0.03 = $6245 - $5,780 = $465
Y = $465/0.03 = $15,500
And X = $34,000 - Y = $34,000 - $15,500 = $18,500
So she invest $18,500 at the 17% rate and $15,500 at the 20% rate.
