Step-by-step explanation:
A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm
---> x^2 = h^2 + (b/2)^2
= (4.8 cm)^2 + (2.5)^2
= 23.04 cm^2 + 6.25 cm^2
or x = 5.41 cm
Therefore, the perimeter P is
P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
Answer:
s = 10500
Step-by-step explanation:
s/5 + 125 = 2225
Our mission is to isolate s. We can first begin to do this by subtracting 125 from both sides.
s/5 + 125 - 125 = 2225 - 125
s/5 = 2100
Since s is being divided by 5, we can multiply by 5 on both sides to get s alone.
s/5 x 5 = 2100 x 5
s = 10500
Answer:

Step-by-step explanation:
Answer:
y-intercept (0,1)
multiplicative rate of change: b
Step-by-step explanation:
If a table represents an exponential function of the form 
, then the y-value that corresponds to x=0 is 1.
In other words, the y-intercept (0,1) must be present in the table.
Also the ratio of a subsequent y-value to the previous y-value should give a value of b.
In other words the multiplicative rate of change from the table must be equal to b.
Answer:
In the problem, the sum of the two functions is 2x + 2
Step-by-step explanation:
For this problem, we have to add together f(x) and g(x).
<em>f(x) = 9 - 3x</em>
<em>g(x) = 5x - 7</em>
(f + g)(x) = (9 - 3x) + (5x - 7)
Combine like terms.
(f + g)(x) = 2x + 2
So, when you combine the two functions together, you will get 2x + 2.
