Answer:
31*
Step-by-step explanation:
right triangle means 90* so 90*-59* = 31*
 
        
                    
             
        
        
        
11. 5x^2-30=0 
+30 to both sides 
5x^2=30
÷5 both sides 
x^2=6
 square root both sides 
x= +square root 6 ,- square root 6
12. 4x^2+10=26
-10 both sides 
4x^2=16
÷4 both sides 
x^2=4
square root both sides 
x=+2,-2
13. a=72yrd^2
l=2w
w=?
a=l×w
72=2w×w
72=2w^2
÷2 both sides 
36=w^2
square root both sides 
w=+6,-6 
a measurement can't be - so w=6 
Plug into l=2w 
l=2×6
l=12
w=6
        
             
        
        
        
Answer:
The resulting graph is  .
.
Step-by-step explanation:
The resulting function is of the form:

Where:
 - Independent variable, dimensionless.
 - Independent variable, dimensionless.
 - Dependent variable, dimensionless.
 - Dependent variable, dimensionless.
 - Amplitude, dimensionless.
 - Amplitude, dimensionless.
 - Midpoint value, dimensionless.
 - Midpoint value, dimensionless.
The sine function is bounded, between -1 and 1, and must be multiplied by a stretch factor. That is:  . According to the graph, the function is bounded between 5 (
. According to the graph, the function is bounded between 5 ( ) and -5 (
) and -5 ( ), and the midpoint value (
), and the midpoint value ( ) is 0. The amplitude is determined by the following calculation:
) is 0. The amplitude is determined by the following calculation:

If  and
 and  , then:
, then:

The resulting graph is  .
.
 
        
             
        
        
        
<span>The initial value is the value of the y-coordinate when the x-coordinate is equal to 0. That is the same to say the value at which the graph intercepts the y-axis. So, you justt have to pick the graph whose line intercepts the y-axis at 1/2. </span>
