Your friend has $90 when he goes to the fair. He spends $5 to enter the fair and $15 on food. Rides at the fair cost $1.50 per r

Maksim231197 [3]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that ,

Total money he takes while going to the fair = $90

Money he spends to enter the fair = $5

Money he spends on food =$15

Total he spent now is given by

$\$5+\$15=\$20$

Now, he spend on rides at the fair i.e. 1.50 per ride .

Let the number of rides be x

So, cost incurred on rides = 1.5x

So, the spending money can be expressed as

$20+1.50x$

Now, remaining money left to him after spending on x rides too is

$90-(1.50x+20)\\\\=90-1.50x-20\\\\=70-1.5x$

Let f(x) denotes the function used to determine the money he has left over after rides .

So it becomes

$f(x)=70-1.50x\\\\f(x)=-1.50x+70$

First differences are 2, 4, 8, 16, which is a geometric sequence. The parent function is not linear (constant first difference) or quadratic (first difference increases by the same amount from one to the next). When the first differences are a geometric sequence, the underlying sequence is a geometric (exponential) sequence.

1st blank: exponential

Translation up adds a constant to each of the f(x) values.

2nd blank: f(x)
3rd blank: increased by 5<span>

For the last blank, you're looking for an (x, f(x)) pair that is translated to (x, f(x)+5).

4th blank: </span><span>(2, 16)</span>

A juice can is in the shape of a cylinder with a diameter of 4 inches. It has a volume of 125 cubic inches. What is the height o

ludmilkaskok [199]

We know that
[volume of a cylinder]=pi*r²*h------> h=volume/[pi*r²]
diameter=4 in
r=4/2---> r=2 in
Volume =125 in³

h=125/[pi*2²]-----> h=9.95 in

the answer is
the height of the can is 9.95 in
