Since ∆STQ ≈ ∆SRQ, then
x=6
m<SRQ= 83°
m<RSQ= 42°
The circumference of a circle is the distance around the outside of the circle. The diameter is the distance across the circle. It must pass through the center or the circle. For any circle, regardless of diameter, there is a consistent ratio between the circle's circumference and the length of its diameter.
Answer:
y(x) = x + 4
Step-by-step explanation:
A function rule is nothing more than a process that correlates changes in input to changes in output. If y is the output and x is the input, the function must be of the form y(x). Since "The output is four more than the input", the value of y is always 4 units greater than the value of x. The function rule is:
Answer:
$13.85
Step-by-step explanation:
If the textbook decreases by 11% per year, this means it will be 89% of the previous year's value since 100% - 11% = 89%
89% in decimal form = 89/100 = 0.89
Therefore, the exponential function is:
, where is the number of years
So when ,
Answer:
x^2+27x+180
Step-by-step explanation:
okay so -12 and 15 are the only solutions
work backward
add 12 and add 15 from x
(x+12)(x+15)
then solve this
x*x=x^2
x*+15=15x
12*x=12x
12*15=180
now put it all together
x^2+15x+12x+180
then simplify
x2+27x+180
(x+12)(x+15)
Then solve again to try it.
x+12=0
x+15=0
x=-12
x=-15
Hope this helps.
