The answer is letter b 15mx20m
3 and 1 are your corresponding angles. So A.
The figure shows a right triangle at each corner with legs 3 and b and hypotenuse 4. The Pythagorean theorem tells you the sum of the squares of the legs is equal to the square of the hypotenuse:
3² + b² = 4² . . . . . . put the numbers into the Pythagorean formula
9 + b² = 16 . . . . . . . evaluate the squares
b² = 16 - 9 = 7 . . . . subtract 9 to isolate the variable
b = √7 . . . . . . . . . . undo the square operation by taking the square root
Answer:
x intercepts at (-3,0), and (1,0)
there is a minimum at (-1,-4)
Step-by-step explanation:
Please see attached image for the requested graph of the function 
, and observe that the crossings of the x-axis are at the points (-3,0), and (1,0) , marked in red in the image.
We can also see that there is no maximum, but a minimum value, and located at the point (-1,-4) [marked in green in the image]
Answer: $12 is % of $16.
Step-by-step explanation:
STEP 1: 100 ÷ 16 = 6.25
STEP 2: <u>12 x 6.25 </u>= <u>75</u>
16 x 6.25 = 100
Now we can see that our fraction is 75/100, which means that 12/16 as a percentage is 75%.
We can also work this out in a simpler way by first converting the fraction 12/16 to a decimal. To do that, we simply divide the numerator by the denominator:
12/16 = 0.75
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.75 x 100 = 75%
hope this helps!
