Answer:
[tex]f(x) = 10*(b)^x[/tex]
Step-by-step explanation:
exponential function : [tex]y=a*(b)^x[/tex]
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x

Math Questions about graph
Answers
Answer:
(i) gradient: 2/3
(ii) equation: y -1 = 2/3(x +1)
(iii) area: 10 square units
(iv) length: 4.12 units
Step-by-step explanation:
The gradient of a line is found by using the slope formula with two points on the line. The length between points is found using the distance formula, which is based on the Pythagorean theorem. The equation of a line can be written in several forms. One is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
__
(i)The points A and B can be used in the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (5 -1)/(5 -(-1)) = 4/6 = 2/3
The gradient of the line is 2/3.
__
(ii)Using the found slope in the point-slope equation with point A, we find the equation of the line to be ...
y -1 = 2/3(x +1)
__
(iii)The area of a triangle is found from the formula ...
A = 1/2bh . . . . . triangle with base b and height h
The base length will be the difference in x-coordinates of the horizontal segment AC: 4 -(-1) = 5.
The height will be the difference in y-coordinates from that horizontal segment and point B: 5 -1 = 4
Then the area of ABC is ...
A = 1/2(5)(4) = 10 . . . . square units
The area of ΔABC is 10 square units.
__
(iv)The length of BC is found from the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -4)² +(5 -1)²) = √(1 +16) = √17
d ≈ 4.12 . . . . units
The length of BC is about 4.12 units.

Two car rental companies have the following payment plans: Cart: $90 per week and 15c per kilometre Renta: $110 per week and 10c per kilometre What is the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta?
Answers
Using linear function concepts, it is found that the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.For each car, Cart and Renta, the linear functions are given by:
C(k) = 90 + 0.15k
R(k) = 110 + 0.1k
Cart will cost less than Renta if:
C(k) < R(k)
Hence:
90 + 0.15k < 110 + 0.5k
0.05k < 20
k < 400
Hence, the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.

For the following system a) What is the value of x? b ) What is the value of y ?
Answers
Answer:
x = 12
y = -23
Step-by-step explanation:
to solve for this i think we have to do:
y = -3x + 13
-
y = -2x + 1
-----------------------
0 = -x + 12
-x = -12
x = 12
then i think.... i think you have to substitute to one of the equations
y = -3(12) + 13
y = -36 + 13
y = -23
then to check we substitute to the second equation
-23 = -2(12) + 1 ?
-23 = -24 + 1?
-23 = -23

Can the side lengths of 7, 10, and 9 form a triangle?
Answers
========================================================
Explanation:
Add the first two sides to get 7+10 = 17 which is larger than the third side (9)Add the first and last sides to get 7+9 = 16 which is larger than the second side (10)Add the last two sides to get 10+9 = 19 which is larger than the first side (7)As that list above shows, adding any two sides results in a sum larger than the third remaining side. The conditions of the triangle inequality theorem have been met to allow for a triangle to be formed.
In general the triangle inequality theorem is:
a+b > ca+c > bb+c > aThe order doesn't matter. All that's important is that all three conditions are met.
