Answer:
f(7) = - 113
Step-by-step explanation:
When u see a function like this it just mean to place the 7 instead of the x(simply put)
so you just fill it in and then simplify:
(-4 x 49) + (10 x 7) + 13 = -113
In the problem, two legs measurement were given such as:
Leg 1 = 12 inches
Leg 2 = 15 inches
We need to solve for the third leg. Since it is a right triangle, we can use Pythagorean theorem in solving the missing leg:
c²=b²+a²
When we assume that the third leg is the "c", we can for the value such as:
c² = 12²+15²
c=19.21
When we assume that the third is either "a" or "b":
15² =a² + 12²
a=9
Then, the possible measurement of the third leg is 9 or 19.21.
The difference between the two possible answer is shown below:
Difference = 19.21 -9 = 10.21
Difference =10.21
make the decimal into into 3
then
3/10×3 =9/10=0.9
To subtract these two numbers, I will convert them into decimal form to make it much easier.
16 1/8 = 16.125
5 3/4 = 5.75.
Now that we have them in decimal form, we can subtract!
16.125 - 5.75 = 10.375
10.375 put into fraction form is 10 3/8.
A.) Matches 10 3/8, so A is your answer.
I hope this helps!
