Step-by-step explanation:
Answer:
y = 4[tex](2)^{x}[/tex]
Step-by-step explanation:
An exponential function in standard form is
y = a[tex]b^{x}[/tex]
Substitute points from the graph into the equation to find a and b
Using (0, 4 ), then
4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so
a = 4
y = 4[tex]b^{x}[/tex]
Using (1, 8 ), then
8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = 2
y = 4 [tex](2)^{x}[/tex] ← exponential equation

Steve is buying an $1160 T.V on the installment plan. He makes a down payments of 200 he has to make monthly payment of 55.25 fo 21/2 years what is his finance charge
Answers
Answer:
Finance charge = $200
Step-by-step explanation:
Cost of the T.V. = $1160
Steve did the down payment = $200
Monthly payment done by Steve = $22.5
Duration for the periodic payments = 2.5 years
Number of periodic payments to be done = 12 × 2.5
= 30
Amount paid in periodic payments = Number of periodic payments done × amount paid in each month
= 30 × $55.25
= $1657.5
Total payment done = Down payment + Amount paid in periodic payments
= $200 + $1657.5
= $1857.5
Therefore, finance charges = Total payments done - cost of T.V.
= 1857.5 - 1657.5
= $200

Answers
what percent is 52.8 of 55? also how did u get itttt
Answers
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55

11√2 is the right answer.At a campground, kayak rental company A charges a fixed amount of $10 plus $8 per hour for renting a one-person kayak. Company B charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
Answers
Answer:
2hours
Step-by-step explanation:
Given data
Company A
charges a fixed amount of $10 plus $8 per hour
let the number of hours be x
and the total be y
y= 10+8x----------------1
Company B
charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
let the number of hours be x
and the total be y
y= 6+10x----------------2
Equate 1 and 2 above
10+8x= 6+10x
collcet like terms
10-6= 10x-8x
4= 2x
x= 2hours
Hence after 2 hours the charges will be the same

Answer:
A. d = 0 -- one (1) solution
B. x = {1, 3.5}
Step-by-step explanation:
A. The discriminant for ax²+bx+c = 0 is ...
d = b² -4ac
For the given equation, this is ...
d = (-36)² -4(9)(36) = 0
The discriminant is zero (0).
The discriminant divided by the leading coefficient (a=2) will give the difference between the two roots of the equation. When the difference is zero, as here, both roots are the same. Effectively, there is one (1) solution to the equation.
__
B. The equation can be factored as ...
2x² -9x +7 = (2x -7)(x -1) = 0
The solutions are the values of x that make the factors be zero:
2x -7 = 0 ⇒ x = 7/2
x -1 = 0 ⇒ x = 1
The solutions are x = 7/2 or x = 1.

Answer:

Step-by-step explanation:
I think you ment 113. a triangle has 180 degrees, the 2 angles add up to 67, subtracted from 180 = 113
anyone got an answer for this (don't mind the 160 i put. That answer is wrong)
Answers
Answer:
140°
Step-by-step explanation:
Angles in a triangle add up to 180
we can see it's an isosceles triangle so the base angles are the same
The missing angle inside the triangle would be...
180 - (70 + 70) = 40°
Angles on a straight line add up to 180
so 180 - 40 = 140°

Answers
Answer: 1 / 3
Step-by-step explanation:
3/9 of the students in the school choir are fourth graders.
To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.
3 factors = 1 , 3
9 factors = 1, 3 , 9
Highest common factor = 3
Divide both numbers by 3
= (3/3) / (9/3)
