Write an exponential function in the form y = abthat goes through points (0, 20)
and (2,180).
1 answer:
Answer:
y=20(6)^x
Step-by-step explanation:
the graph passes through the point (0,20) : when x=0 and y=20 :
20= ab^0 so a=20 because : b^0 = 1
the graph passes through the point (3,4320) : when x=3. and y=4320 : 4320= ab^3 but : a=20 so : 4320 = 20b^3
so : b^3 = 4320/20 = 216...... 216 = 6^3
b^3 = 6^3
b=6
the function is : y=20(6)^x

Answer:
138
Step-by-step explanation:
70 + 32 = 102
102 + 36 = 138
138 + 40 = 178
178 + 44 = 222
Check the picture below.
you can pretty much count the units for the base and its height off the grid.
first u multiply 94 ft times 46 ft to get the area. U get 4324. Next u multiply that by 3.25 to get the resurfacing cost
The answer is $14053.
Hope that helps!
It is a rational number because 98.45 can be turned into a fraction.
Answer:
Second option: -3x^2
Step-by-step explanation:
A is the product of -x and 3x, then:
A=(-x)(3x)→A=-3x^2
