Write an exponential function to describe the given sequence of numbers, assuming that the first number in the sequence corresponds to x = 0.
5.30, 180, 1080, 6480...
Answer:
[tex]y = 5(6) {}^{x} [/tex]
Step-by-step explanation:
A exponential function is represented by
[tex]y = ab {}^{x} [/tex]
where a is the vertical stretch and b is the base and x is the nth
power of x
Since the first number corresponds with zero, that means our y intercept is the first number.
This means when x=0 , y=5 so let find the value of 5.
[tex]5 = ab {}^{0} [/tex]
b to the 0th power equal 1 so
[tex]5 = a \times 1[/tex]
[tex]a = 5[/tex]
Our equation is for now
[tex]y = 5b {}^{x} [/tex]
Now let plug in 1,30
[tex]30 = 5b {}^{1} [/tex]
Divide 5 by both sides
[tex]6 = b {}^{1} [/tex]
Anything to the 1st power is itself so b equal 6.
So our equation is
[tex]y = 5(6) {}^{x} [/tex]

Find the measure of the angle indicated in bold.
Answer:
125°
Step-by-step explanation:
16x - 3 = 14x + 13 (vertical angles)
16x - 14x = 13 + 3
2x = 16
x = 16/2
x = 8
(16x - 3)° = (16*8 - 3)° = (128 - 3)° = 125°

Answer: 15h^2 + 26h -21
Step-by-step explanation:
Use the foil method. Multiply in this order
First, 5h*3h= 15h^2
outer, 5h*7 = 35h
inner, -3*3h= -9h
last, -3*7= -21
Now add them all together
15h^2 + 35h + -9h + -21
Combine like terms
15h^2 + 26h -21

If x= 5 and y = 2, work out the value of a) 3x + y
b) 2x2
c) (x - y)2
Answer:
17, 50, 9
Step-by-step explanation:
Hello
We already know the values of x and y, 5 and 2.
All we have to do to figure out a, b, and c, is to plug in those known values.
a) 3x + y
Let's plug in x and y as 5 and 2
3(5) + 2
15 + 2
17
b) 2x^2
2(5)^2
2(25)
50
c) (x - y)^2

Answer:
A) 3(5)+2= 17
B) 2(5)2= 50

Answer: x= 10
Step-by-step explanation:
Same side exterior angles sum to 180.
Using this axiom we can say that
142+ (3x+8) = 180
Add like terms on the left side
150+ 3x = 180
Subtract 150 from both sides
3x = 30
Divide both sides by 3
X= 10

Answer: P(Quarter & Penny): 9/100
p(Two pennies): 9/25
Step-by-step explanation:
There are 20 coins in the bag, so you have a 3/20 chance of getting a quarter, 5/20 chances of getting a dime and 12/20 chance of getting a penny on each draw if the coins are always replaced.
Im this situation, you can simplify the fractions, the
Multiply the chance of each independent event times the chance of the next independent event.
3/20 × 3/5 = 9/100 for the quarter and the penny
3/5 × 3/5 = 9/25 for the two pennies

Answer: 9/7
Step-by-step explanation:
Use a product of two binomials to find a polynomial that represents the area of Roberto's plot.
Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2

Answer:
A. All motion is relative to the frame of reference chosen for measurement.
Step-by-step explanation:
Student 1 riding in the car is going at a certain speed. He sees the bus going a bit faster, so he thinks the bus is going at 20 km/h because to him, since he is also moving, it seems that the bus is only a little faster. Student 2 is on the sidewalk standing. He is not moving. When he sees the bus moving, the bus seems to be going fast because he is not moving. He estimates the speed of the bus to be 50 km/h.
The difference in estimates is due to their frames of reference.
Answer: A. All motion is relative to the frame of reference chosen for measurement.

Express the number of months in the year that are only 4 letters as a fraction in the simplest form, decimal rounded to the nearest thousandth and whole percent.
Answer:
There are only 2 months out of the 12 that have 4 letters in their name so it would be represented as 2/12, the numerator representing those 2 months and the numerator representing the 12 months in 1 year. 2/12 in its simplest form would be 1/6 because if you use the big one to simplify 2/12 and divided it by 2/2 you get 1/6. 1/6 as a decimal is 0.16 wich is 16% as a percent.

What is the domain of the function?
X+6
f(x)=(x-7)(x+5)
A all real numbers except 7
Ball real numbers except 5 and -7
Call real numbers except -5 and 7
D all real numbers
The required domain of the function is all real numbers except -5 and 7. Option C is correct.
Given that,
f(x) = (x + 6) /[(x-7)(x+5)]
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
Given function,
f(x) = (x + 6) /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.
Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

Today, Reza ate 20 grapes, which was 400% as many
grapes as he ate yesterday. Explain how to use
equivalent ratios to find the number of grapes Reza ate
yesterday. (help plz)
its not a sin to want to win cant see meflying like a bee i see a dreamer other there by the water but i
LOL
Answer:
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5

We have given that the
10x 10 x 10 x 10
We have to find the multiplication of the above 10.
What is multiplication?Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division.
here we have
10 x10=100
10x100=1000
10x1000=10000
Therefore the multiplication of 10x 10 x 10 x 10 is 10000.
